User interface  272  may, for example, include at least one of a display, touch screen, buttons, light indicators, etc. In some embodiments, controller  270  may receive preferences of a user of device  200 , related to modes of operation and operation parameters, via user interface  272 . For example, the user&#39;s preferences may include a type of biological material and/or fatty compounds to be extracted, a desired concentration of the fatty compounds in the liquid mixture, a desired viscosity of the liquid mixture, etc. Controller  270  may determine operation parameters for device  200  based on the user&#39;s preferences. Controller  270  may provide instruction to the user of device  200  via user interface  272  (e.g., visual instructions, audio instructions, etc.). 
     Device  200  may include sensors (collectively referred hereinafter as “sensors  274 ”), pumps (collectively referred hereinafter as “pumps  276 ”) and valves (collectively referred hereinafter as “valves  278 ”). Sensors  274 , pumps  276  and valves  278  may be in communication (e.g., wired and/or wireless) with controller  270 . Controller  270  may receive readings from sensors  274  and may control pumps  276  and valves  278  to operate various units of device  200  based on the readings of sensors  274  and/or according to the predetermined operation program. 
     Controller  270  may control extraction of fatty compounds from biological material into the liquid mixture using the liquid solvent, evaporation of the solvent from the liquid mixture, optionally dilution the liquate mixture with the diluting liquid, optionally induction of the specified chemical reaction of at least one component of the liquid mixture (e.g., decarboxylation of Hemp), storage of the liquid mixture and filling of capsule(s)  290  with the liquid mixture for further distribution/consumption. 
     The description made below with respect to  FIG. 2  presents an example of a process that may be performed by device  200  to extract, store and encapsulate the extracted fatty compounds. Functions being performed by different units of device  200  may be controlled by controller  270  via pumps  276  and valves  278  and based on readings of sensors  274  and operation parameters determined based on the user&#39;s preferences. Advantageously, device  200  may enable fully automated, self-operated extraction, storage and encapsulation of the fatty compounds. 
     At first stage, controller  270  may prompt, via user interface  272 , the user of device  200  to place a desired biological material within filter  222  of extraction unit  220  via an input lid. Controller  270  may prompt the user to select, via user interface  272 , user&#39;s preferences concerning, for example, a type of biological material and/or fatty compounds to be extracted, an amount of the biological material, a desired concentration of the fatty compounds in the liquid mixture, a desired viscosity of the liquid mixture, etc. 
     Controller  270  may determine the operation parameters for device  200  based on the user&#39;s preferences. The operation parameters may, for example, include at least one of: a required amount of the solvent liquid, a required extraction time interval, indication whether dilution is required or not, a required amount of the diluting liquid, indication whether the specified chemical reaction (e.g., decarboxylation) is required or not, temperature for the specified chemical reaction, time interval for the chemical reaction, etc. 
     In some embodiments, controller  270  may determine whether the input lid of extraction unit  220  is closed or open. For example, device  200  may include an input lid sensor  274   a  configured to indicate whether the input lid of extraction unit  220  is closed or open. Controller  270  may prevent operation of device  200  if input lid sensor  274   a  indicates that the input lid is open. In this case, controller  270  may, for example, instruct the user, via user interface  272 , to close the input lid. 
     In some embodiments, controller  270  may determine whether solvent supply unit  260  contains the required amount of the liquid solvent. For example, device  200  may include a first liquid amount sensor  274   b  (e.g., liquid level sensor) configured to measure an amount of the liquid solvent within solvent container  262  and/or solvent storage chamber  264  of solvent supply unit  260 . Controller  270  may prevent operation of device  200  if there is no required amount of the liquid solvent in solvent supply unit  260 . In this case, controller  270  may, for example, instruct the user, via user interface  272 , to replace and/or to fill solvent container  262  or solvent storage container  264  with the liquid solvent. 
     In some embodiments, controller  270  may determine whether there is a sufficient volume in storage container(s)  242  of storage unit  240  to accommodate the volume of the liquid mixture to be produced during current operation cycle. For example, device  200  may include a second liquid amount sensor  274   c  (e.g., liquid volume sensor/liquid level sensor) configured to measure a volume of the liquid mixture contained within storage container(s)  242 . Controller  270  may prevent operation of device  200  if there is no sufficient volume in storage container(s)  242  to accommodate the volume of the liquid mixture to be produced during current operation cycle. In this case, controller  270  may, for example, instruct the user, via user interface  272 , to empty/partly empty storage container(s)  242 . 
     At next stage, controller  270  may control a supply of the liquid solvent from solvent supply unit  260  to extraction unit  220 . For example, device  200  may include a first pump  276   a  disposed downstream solvent supply unit  260  and upstream extraction unit  220 . Controller  270  may control solvent pump  276   a  to pump the liquid solvent from solvent storage container  264  of solvent supply unit  260  to extraction unit  220  (e.g., through filter  222  and/or directly to extraction chamber  224 ). 
     In some embodiments, controller  270  may determine that extraction chamber  224  of extraction unit  220  contains the required amount of the liquid solvent and control solvent pump  276   a  to stop the pumping. For example, device  200  may include a third liquid amount sensor  274   d  (e.g., liquid level sensor) configured to measure the amount of the liquid solvent within extraction chamber  224  of extraction unit  220 . 
     At next stage, controller  270  may optionally control a circulation of the liquid solvent/the liquid mixture containing the liquid solvent and fatty compounds extracted from the biological material. For example, controller  270  may control first pump  276   a  to pump the liquid mixture from downstream of extraction chamber  224  of extraction unit  220  to upstream thereof, possibly via filter  222  or directly to extraction chamber  224 . For example, device  200  may include a first valve  278   a  (e.g., 3-way valve) that may be controlled by controller  270  to switch between pumping the liquid solvent and circulation of the liquid mixture. 
     In some embodiments, device  200  may include a heater/cooler  280 . Controller  270  may control heater/cooler  280  to cool or heat the liquid solvent and/or the liquid mixture being circulated. The measure of cooling or heating may be determined based on the determined operation parameters. 
     In some embodiments, controller  270  may control first pump  276   a  to stop circulation of the liquid solvent/liquid mixture after the predetermined extraction time interval. The extraction time interval may be determined based on the predetermined operation parameters (e.g., temperature of the liquid solvent/liquid mixture). 
     At next stage, controller  270  may optionally control deformation or spinning of filter  222  of extraction unit  220  to squeeze the biological material contained within filter  222 . The deformation/spinning may remove residuals of the liquid mixture from the biological material. For example, filter  222  may be deformable (e.g., as described below with respect to  FIG. 4 ) and extraction unit  220  may include a filter deforming mechanism  226  adapted to deform (e.g., press or twist) filter  222 . 
     At next stage, controller  270  may control evaporation of the solvent from the liquid mixture. Controller  270  may open a second valve  278   b  (e.g., 2-way valve) disposed downstream to extraction chamber  224  of extraction unit  220  and upstream to evaporation and reaction chamber  232  of evaporation and reaction unit  230  to enable the liquid mixture to flow from extraction chamber  224  to evaporation and reaction chamber  232 . For example, controller  270  may keep second valve  278   b  open for a predetermined time interval, upon which controller  270  may close second valve  278   b . In some embodiments, device  200  may include a dedicated pump for delivering the liquid mixture from extraction chamber  224  of extraction unit  220  to evaporation and reaction chamber  232  of evaporation and reaction unit  230 . 
     Controller  270  may control heating element(s)  234  to heat the liquid mixture above a boiling temperature of the liquid solvent to evaporate the solvent from the liquid mixture. Condenser  264  of solvent supply unit  260  may collect evaporated solvent from evaporation and reaction chamber  232  of evaporation and reaction unit  230 , condense the evaporated solvent into the liquid solvent and supply the liquid solvent to solvent storage chamber  264 . 
     In some embodiments, device  200  may include a temperature sensor  274   e  configured to measure a temperature of the liquid mixture. Controller  270  may control the heating element(s)  234  based on readings of temperature sensor  274   e  to ensure a desired temperature within evaporation and reaction chamber  232 . 
     In various embodiments, controller  270  may stop evaporation of the solvent upon a predetermined evaporation time interval or when a pressure of the evaporated solvent within evaporation and reaction chamber reduces below a predetermined pressure value. The evaporation time interval may be predetermined based on, for example, the predetermined operation parameters (e.g., the amount of the liquid solvent being used, etc.). The pressure of the evaporated solvent within evaporation and reaction chamber  232  may be determined based on readings of a pressure sensor  274   f.    
     At next stage, controller  270  may optionally control diluting of the liquid mixture with the diluting liquid. Controller  270  may control a second pump  276   b  configured to pump the diluting liquid from diluting liquid container  252  of diluting liquid unit  250  to evaporation and reaction chamber  232  of evaporation and reaction unit  230 . The amount of required diluting liquid may be determined based on the predetermined operation parameters (e.g., desired viscosity of the liquid mixture, etc.) In some embodiments, controller  270  may control second pump  276   b  to pump the diluting liquid for a predetermined time interval. The time interval may be determined based on, for example, the required amount of the diluting liquid and based on rheological properties of the diluting liquid. In some embodiments, diluting of the liquid mixture with the diluting liquid may be performed before evaporation of the solvent from the liquid mixture. 
     In some embodiments, controller  270  may determine whether diluting liquid container  252  of diluting liquid unit  250  contains a required amount of the diluting liquid. For example, device  200  may include a fourth liquid amount sensor  274   f  (e.g., liquid level sensor) configured to measure an amount of the diluting liquid within diluting liquid container  252 . Controller  270  may prevent operation of device  200  or terminate the operation thereof if there is no required amount of the diluting liquid in diluting liquid container  252 . In this case, controller  270  may, for example, instruct the user, via user interface  272 , to replace and/or to fill diluting liquid container  252  with the diluting liquid. 
     At the next stage, controller  270  may optionally control heating element(s)  234  to heat the liquid mixture (e.g., containing the extracted fatty compounds and the diluting liquid) above a specified temperature value to induce at least one component of the liquid mixture undergo a specified chemical reaction. For example, if liquid mixture contains cannabinoids fatty compounds, heating the liquid mixture above a decarboxylation temperature of cannabinoids may cause decarboxylation of cannabinoids and thus get the cannabinoids ready for use. 
     In some embodiments, controller  270  may control heating element(s)  234  based on readings of temperature sensor  274   e  (e.g., to ensure the required reaction temperature within evaporation and reaction chamber  232 ) and for a predetermined reaction time interval (e.g., decarboxylation time interval). The reaction time interval may be determined based on the predetermined operation parameters and/or parameters of the at least one component undergoing the chemical reaction (e.g., each cannabinoid may have few decarboxylation set points of temperature and time). 
     In some embodiments, the chemical reaction may be induced before dilution of the liquid mixture with the diluting liquid. In some embodiments, device  200  may include a dedicated reaction unit (e.g., being not a part of evaporation and reaction unit  230 ). 
     At next stage, controller  270  may control delivery of the liquid mixture (e.g., containing mainly fatty compounds, optionally containing decarboxylated fatty compounds, optionally containing the diluting liquid) from evaporation and reaction chamber  232  of evaporation and reaction unit  230  to storage unit  240 . For example, controller  270  may open a third valve  278   c  disposed downstream evaporation and reaction chamber  232  of evaporation and reaction unit  230  and upstream storage container(s)  242  of storage unit  240  to enable flow of the liquid mixture from evaporation and reaction chamber  232  to storage container(s)  242 . In some embodiments, device  200  may include a dedicated pump for pumping the liquid mixture from evaporation and reaction chamber  232  to storage container(s)  242 . 
     At next stage, controller  270  may control filling of capsule(s)  290  with the liquid mixture from storage unit  240 . Capsule(s)  290  may be removably connectable to storage outlet port(s)  244  of storage unit  240 . Upon the connection of capsule(s)  290  to storage outlet port(s)  244  fluid connection may be established therebetween. Controller  270  may determine that capsule  290  has been properly connected to storage outlet port  244 . For example, device  200  may include a capsule connection sensor  274   g  configured to detect that capsule  290  has been properly connected to storage outlet port  244 . Capsule connection sensor  274   g  may, for example, include an RFID-based sensor, optical sensor, etc. Upon detection of proper connection of capsule  290  to storage outlet port  244 , controller  270  may control a third pump  276   c  to pump a desired amount of the liquid mixture into capsule  290 . For example, controller  270  may control third pump  276   c  to pump the liquid mixture for a predetermined time interval to fill the desired amount of the liquid mixture into capsule(s)  290 . The time interval may be determined based on the operation parameters (e.g., the desired amount of the liquid mixture, etc.). 
     In some embodiments, controller  270  may determine whether storage container(s)  242  contain the required amount of the liquid mixture to be filled into capsule  290  based on readings of second liquid amount sensor  274   c  and the operation parameters. Controller  270  may prevent filling of capsule  290  if there is no required amount of the liquid mixture in storage container(s)  242 . In this case, controller  270  may notify the user, via user interface  272 , that there is no required amount of the liquid mixture to fill capsule  290 . 
     Capsule(s)  290  may be removed from storage outlet port  244  of storage unit  240  upon filling thereof with the liquid mixture and used to distribute/consume the liquid mixture. Some embodiments of capsule  290  are described below with respect to  FIGS. 7 and 8 . 
     In some embodiments, device  200  may include one or more capsules  290 . For example, device  200  may be supplied with one or more capsules  290 . Some embodiments of the present invention may provide a kit including device  200  and one or more capsules  290 . 
     In some embodiments, controller  270  may control a cleaning process of device  200 . For example, controller  270  may notify the user via user interface  272  that cleaning of device  200  is required. For example, the cleaning may be required after a predefined number of operational cycles. The cleaning process may be initiated upon, for example, receipt of respective instructions from the user via user interface  272 . 
     One example of the cleaning process may include circulating and evaporating the liquid solvent (e.g., as described above with respect to  FIG. 2 ) while extraction unit  220  is empty of the biological material. 
     Another example of the cleaning process may include circulating and evaporating the liquid solvent (e.g., as described above with respect to  FIG. 2 ) while extraction unit  220  is empty of the biological material, filling storage container(s)  242  with liquid cleaning residuals and removing liquid cleaning residuals using a dedicated cleaning capsule. 
     It is noted that each of units of device  200  may include fluid conduit(s) and connectors that provide fluid communication between components of these units and/or between different units thereof, as described above and shown in  FIG. 2 . It is also noted that other sensors  274 , pumps  276 , valves  278  and combinations thereof may be used according to specifications of device  200  and/or based on relative spatial configuration of different units of device  200  with respect to each other.

     Filter  300  may include a filtering compartment  310  adapted to receive and accommodate a predefined amount of biological material. In some embodiments, filtering compartment  310  may include a frame  312  that supports a filtering material  314  (e.g., as shown in  FIG. 3A ). Filtering compartment  310  may include an aperture  316  through which biological material may be introduced into an interior  311  of filtering compartment  310 . Frame  312  may be made of, for example, plastic. Filtering material  314  may be made of, for example, filtering paper or filtering fabric. 
     Filter  300  may include one or more conduits  320  each including multiple sprinkling holes or sprinklers  322  (e.g., as shown in  FIG. 3A ). Sprinkling holes or sprinklers  322  may face interior of  311  of filtering compartment  310 . Conduit(s)  320  may deliver a liquid solvent and to sprinkle the liquid solvent into filtering compartment  310  through sprinkling holes or sprinklers  322  (e.g., as shown in  FIG. 3A ). 
     In some embodiments, filter  300  may include a covering  330  adapted to removably cover aperture  316  of filtering compartment  310 . In some embodiments, covering  330  may include a frame  332  (e.g., similar to frame  312 ) that supports a filtering material  334  (e.g., similar to filtering material  314 ). In various embodiments, conduit(s)  320  may be disposed within or attached to covering  330  (e.g., as shown in  FIG. 3A ). In some embodiments, conduit(s)  320  may be disposed within filtering compartment  310 . In general, conduit(s)  320  may be disposed at any spatial location and configuration within filter  300  that enables sprinkling of the liquid solvent into interior  311  of filtering compartment  310  through sprinkling holes or sprinklers  322 . 
     In some other embodiments, filtering compartment  310  may, for example, be a closed compartment, prefilled with biological material. In these embodiments, filter  300  may not include any covering. Yet in these embodiments, conduit(s)  320  may be disposed within interior  311  of filtering compartment  310 . 
     Filter  300  may include one or more fluid connectors  324  (e.g., as shown in  FIG. 3A ). Fluid connector(s)  324  may be in fluid communication with conduit(s)  320 . Fluid connector(s)  324  may be removably connectable to a liquid solvent supply conduit and enable delivery of the liquid solvent from the liquid solvent supply conduit to conduit(s)  320 . 
     In embodiments shown in  FIG. 3A , filter  300  includes a first fluid connector  324   a  and a second fluid connector  324   b . First fluid connector  324   a  may be disposed within or attached to covering  330  and may be fluid communication with conduit(s)  320 . Second fluid connector  324   b  may extend through filtering compartment  310  and may be removably connectable at its first end to first fluid connector  324   a  and removably connectable at its second end to the liquid solvent supply conduit. 
     It is noted that other configurations of filtering connector(s)  324  are also possible. For example, filter  300  may include a single fluid connector (e.g., such as first filtering connector  324   a ) that may be externally connectable to the liquid solvent supply conduit (e.g., and not through filtering compartment  310  as shown in  FIG. 3A ). 
     Filter  300  may have different shapes. Filter  300  may have different dimensions. For example, filter  300  may be adapted to accommodate 10 gr, 20 gr or 30 gr of biological material (e.g.,  Cannabis  plant). For example, filter  300  that is adapted to accommodate 30 gr of biological material may be larger than filter adapted to accommodate 20 gr of biological material. 
     Reference is now made to  FIG. 3B , which is a schematic illustration of a filtering unit  301  including two or more filters  300   a ,  300   b ,  300   c , according to some embodiments of the invention. 
     In some embodiments, two or more filters may be connected in series to form a filtering unit  301  (e.g., as shown in  FIG. 3C ). For example,  FIG. 3C  depicts filtering unit  301  that includes three filters connected in series—a first filter  300   a , a second filter  300   b  and a third filter  300   c , each similar to filter  300  described above with respect to  FIGS. 1A and 1B . In some embodiments, filters  300   a ,  300   b ,  300   c  may be in fluid communication with each other, for example, through their respective fluid connectors. Filtering unit  301  may, for example, enable to increase an amount of biological material and an amount of fatty compounds that may be extracted from biological material as compared to single filter  300 . 
     Reference is now made to  FIG. 3C , which is a schematic illustration of a filter  302  including a housing  340 , according to some embodiments of the invention. 
     Filter  302  may be similar to filter  300  described above with respect to  FIG. 1A . For example, filter  302  may include a filtering compartment  310  (not shown in  FIG. 1C ), conduit(s)  320  with sprinkling holes or sprinklers  322  (not shown in  FIG. 1C ), covering  330 .

     In some embodiments, filters  300 ,  302  may be deformable (e.g., as described below with respect to  FIG. 4 ). 
     Reference is now made to  FIG. 4 , which is a schematic illustration of a deformable filter  400 , according to some embodiments of the invention. 
     Filter  400  may include a filtering compartment  410  adapted to receive and accommodate a predefined amount of biological material. 
     In some embodiments, filtering compartment  410  may include an aperture  416  through which biological material may be introduced unto an interior of filtering compartment. In some embodiments, filter  400  may include a covering  430  adapted to removably cover aperture  416  of filtering compartment  410  (e.g., as shown in  FIG. 4 ). 
     In some other embodiments, filtering compartment  410  may, for example, be a closed compartment, prefilled with biological material. 
     In some embodiments, filtering compartment  410  may include a frame  412  that supports a filtering material  414 . Frame  412  may be made of, for example, flexible plastic. Filtering material  414  may be made of, for example, filtering paper or filtering fabric. 
     Flexible frame  412  may enable deformation of at least filtering compartment  410  of filter  400 . For example, filtering compartment  410  may be pressed or twisted to at least partly collapse filter compartment  410 . This may, for example, enable squeezing of biological material contained within filtering compartment  410  to remove residuals of the liquid mixture therefrom. 
     In embodiments shown in  FIG. 4 , filter  400  may include two catchers  440  oppositely disposed along a lateral surface of filtering compartment  410 . At least one of catchers  440  may be rotatable (e.g., manually or using a dedicated rotating mechanism) to twist filtering compartment  410 . 
     Filter  400  may be used in a device for extracting and storing fatty compounds (e.g., device  100  and device  200  described hereinabove). For example, filter  400  may be used as a filter in the extraction unit of the device (e.g., filter  122  and filter  222  described hereinabove). 
     Reference is now made to  FIG. 5 , which is a schematic illustration of an evaporation and reaction unit  500 , according to some embodiments of the invention. 
     Evaporation and reaction unit  500  may be used in a device for automatic extraction, storage and encapsulation of fatty compounds (e.g., device  100  and device  200  described hereinabove). For example, evaporation and reaction unit  500  may be used as evaporation and reaction unit  130  or evaporation and reaction unit  230  as described hereinabove. 
     Evaporation and reaction unit  500  may include an evaporation and reaction chamber  510  and one or more heating elements  520 . 
     Evaporation and reaction chamber  510  may include an inlet  512  through which liquid mixture containing liquid solvent and extracted fatty compounds may be introduced into evaporation and reaction chamber  510 . Inlet  512  may be disposed at, for example, an upstream portion  511  of evaporation and reaction chamber  510 . 
     Heating element(s)  520  may be controllable by, for example, a controller of the extracting and storing device (e.g., such as controller  170  and controller  270  described hereinabove). Heating element(s)  520  may be controlled to heat the liquid mixture within extraction chamber  510  above a boiling temperature of the liquid solvent to evaporate the solvent from the liquid mixture. 
     Evaporation and reaction chamber  510  may include an evaporation outlet  513  through which evaporated solvent may exit from evaporation and reaction chamber  510  to, for example, condenser (e.g., as described above with respect to  FIGS. 1 and 2 ). Evaporation outlet may be disposed at, for example, upstream portion  511  of evaporation and reaction chamber  510 . 
     In some embodiments, evaporation and reaction chamber  510  may be tapered in a direction extending between upstream portion  511  and downstream portion  514  thereof. This may, for example, direct the liquid mixture towards downstream portion  514  of evaporation and reaction chamber  510 . 
     In some embodiments, evaporation and reaction chamber  510  may include a diluting liquid inlet  515  through which diluting liquid may be introduced into evaporation and reaction chamber  510  (e.g., as described above with respect to  FIGS. 1 and 2 ). Diluting liquid inlet  515  may be disposed at, for example, upstream portion  511  of evaporation and reaction chamber  510 . In some embodiments, diluting liquid  515  may be introduced to evaporation and reaction chamber  510  through liquid mixture unlet  512 . Diluting liquid may be introduced into evaporation and reaction chamber  510  prior to, during or after evaporation of solvent from the liquid mixture is complete (e.g., as described above with respect to  FIG. 2 ). Upon introduction of the diluting liquid into evaporation and reaction chamber  510 , the liquid mixture may contain mainly fatty compounds and the diluting liquid. 
     In some embodiments, evaporation and reaction chamber  510  may include a liquid mixture compartment  516 . Liquid mixture compartment  516  may be disposed at downstream portion  514  of evaporation and reaction chamber  510 . Liquid mixture compartment  516  may accommodate the liquid mixture that has not been evaporated. For example, a volume of liquid mixture compartment  516  may be set based on a maximal volume of liquid mixture that may be produced by the extracting and storing device during one operational cycle. 
     In some embodiments, heating element(s)  320  may be controlled (e.g., by the controller of the evaporating and storing device) to heat the liquid mixture accommodated within liquid mixture compartment  516  (e.g., containing the extracted fatty compounds and optionally the diluting liquid) above a specified temperature value to induce at least one component of the liquid mixture undergo a specified chemical reaction (e.g., where applicable). For example, if liquid mixture contains cannabinoids fatty compounds, heating the liquid mixture above a decarboxylation temperature of cannabinoids may cause decarboxylation of cannabinoids and thus get the cannabinoids ready for use. 
     In some embodiments, heating element(s)  320  may be disposed adjacent (or substantially adjacent) to liquid mixture compartment (e.g., as shown in  FIG. 5 ). This may, for example, enable uniform (or substantially uniform) heating of the liquid mixture accommodated within liquid mixture compartment  516  to enhance the chemical reaction of the at least one component thereof (e.g., decarboxylation of cannabinoids fatty compounds). 
     Evaporation and reaction chamber  510  may include a liquid mixture outlet  518  through which liquid mixture may exit from evaporation and reaction chamber  510 . Liquid mixture outlet  514  may be disposed at, for example, downstream portion  514  of evaporation and reaction chamber  510 , e.g., at liquid mixture compartment  516  (e.g., as shown in  FIG. 5 ). 
     Inflow and outflow of fluids into/from evaporation and reaction chamber  510  may be controlled by valves and pumps based on readings of sensors attached to or disposed within evaporation and reaction chamber  510 , for example as described above with respect to  FIG. 2 . In various embodiments, evaporation and reaction unit  500  may include sensors, pumps and valves that may enable control of evaporation and reaction unit  500  (e.g., as described above with respect to  FIG. 2 ).

     Reference is now made to  FIG. 8 , which is a schematic illustration of a second embodiment of a capsule  800 , according to some embodiments of the invention. 
     Capsule  800  may be used in a device for automatic extraction, storage and encapsulation of fatty compounds, such as device  100 ,  200 ,  600  as described hereinabove. For example, capsule  700  may be similar to capsule  190 ,  290 ,  690  described hereinabove. 
     In some embodiments, capsule  800  may include a flexible reservoir  810 . Reservoir  810  may include one or more apertures through which liquids may be introduced therein. 
     In some embodiments, reservoir  810  may include an inlet  812  through which liquid may be introduced into reservoir  812 . For example, inlet  812  may be removably connectable to storage outlet port(s) (e.g., such as storage outlet port(s)  144 ,  244 ,  644  described hereinabove) of the extracting and storing device (e.g., such as device  100 ,  210 ,  610  described hereinabove) and enable introduction of the liquid mixture from the storage container(s) (e.g., storage container(s)  142 ,  242 ,  642  described hereinabove). In some embodiments, inlet  812  may be used to pre-fill capsule  800  with a specified liquid before filling it by the extracting and storing device. Inlet  812  may enable introduction of the liquid into reservoir  810  and prevent from liquid to exit from inlet  812  when, for example, reservoir  810  being collapsed. For example, inlet  812  may include a 1-way valve. 
     In some embodiments, reservoir  810  may include an outlet  814 . Outlet  814  may enable outflow of the from reservoir  810  when, for example, reservoir  810  is being pressed or collapsed and prevent outflow of liquid form reservoir  810  when reservoir  810  is in a resting state. For example, outlet  814  may include a 1-way valve. 
     In some embodiments, capsule  800  may include a pressure applicator  820 . Pressure applicator  820  may be configured to apply pressure to flexible reservoir  810  to thereby press or collapse reservoir  810 . In some embodiments, pressure applicator  820  may include a first arm  822  and a second arm  824  connected at one of their ends by an arms-connector  826 . Flexible reservoir  810  may be, for example, connected at its first end to arms-connector  826 . First arm  822  and second arm  824  may be made of, for example, elastic material (e.g., plastic). First arm  822  and second arm  824  may be pressed against each other to collapse reservoir  810  and may return to their initial state when the pressure is released. It is noted that other configurations of the pressure applicator are also possible. 
     In some embodiments, pressure applicator  820  may be configured to empty a single drop of the liquid mixture from reservoir  810  with a single pressure application. For example, first arm  822  and second arm  824  may include a first protrusion  823  and a second protrusion  825  at their free (e.g., unconnected) ends. When first arm  822  and second arm  824  are pressed and collapse reservoir  810 , liquid mixture contained within reservoir  810  flows from reservoir  810  through outlet  814  until first protrusion  823  and second protrusion  825  contact each other and block the passage of the liquid mixture. In this manner, a single drop of the liquid mixture may be emptied from reservoir  810  with a single pressure application. The measure of protrusion of first protrusion  823  and second protrusion  825  from first arm  822  and second arm  824 , respectively, may be predetermined based on a desired volume of drop to be emptied from reservoir  810  with a single pressure application. 
     In some embodiments, capsule  800  may include a capsule identifier  830 . Capsule identifier  730  may store capsule-related information.

     Some embodiments may provide a provides an evaporator  2120  configured to heat a mixture of multiple liquids and evaporating at least one of the liquids, while collecting at least one other liquid. According to some embodiments, described above, the evaporator  2120  includes an upper compartment  2121 , a lower compartment  2124  below the upper compartment  2121 , and a heating element  2122  attached to the upper compartment  2121 , or to the lower compartment  2124 , or to the upper compartment  2121  and the lower compartment  2124 . The heating element  2122  is configured to heat a mixture of multiple liquids inside the evaporator  2120 . 
     According to some embodiments, the inner structure of the upper compartment  2121  is configured to direct any liquid present in the upper compartment  2121  toward the lower compartment  2124 . This inner structure of the upper compartment  2121  increases the efficiency of collecting substantially all the liquid that is left in the evaporator  2120  after at least on other type of liquid is evaporated. If, for example the bottom of the upper compartment  2121  was flat, and the walls of the upper compartment  2121  were perpendicular, a great amount of the liquid that is not evaporated is left in the upper compartment  2121  and is not collected in the lower compartment  2124 . Therefore, an exemplary inner structure of the upper compartment  2121  is a funnel-like structure, as illustrated in  FIG. 16B . This ensures that any liquid remaining in the upper compartment  2121  is directed towards the lower compartment  2124 . It should be noted that the funnel-like inner structure of the upper compartment  2121 , illustrated in  FIG. 16B , should not be considered as limiting the scope of the present subject matter. Any type of structure that direct substantially all of the liquid in the upper compartment  2121  towards the lower compartment  2124  is under the scope of the present subject matter. 
     According to some embodiments, the evaporator  2120  includes an evaporator outlet  125  at the bottom of the lower compartment  2124 , as illustrated in  FIGS. 16B and 16D . Thus, the inner structure of the lower compartment  2124  is configured to direct all the liquid that is in the lower compartment  2124  toward the evaporator outlet  125 . Therefore, embodiments of the structure of the lower compartment  2124  are similar to the embodiments of the structure of the upper compartment  2121  described above. 
     According to some embodiments, the evaporator  2120  is configured to receive a mixture of multiple liquids and heat the mixture of the multiple liquids. According to some embodiments, the evaporator  2120  is configured to evaporate at least one of the liquids of the mixture, while retaining at least one of the liquids of the mixture. According to some embodiments, the at least one liquid that is to be evaporated has a lower density than the at least one liquid that is to be retained, and the boiling point of the at least one liquid that is to be evaporated is lower than the boiling point of the at least one liquid that is to be retained. For the sake of simplicity only, an exemplary mixture of liquids is a mixture of an alcohol and an oil, for example ethanol and soybean oil. Ethanol has a density of substantially 0.79 gr/ml and a boiling point of substantially 78° C. Soybean oil has a density of substantially 0.9 gr/ml and a smoke point of substantially 257° C. Oils have a smoke point that is the temperature in which they start to disintegrate, or burn, and a theoretical boiling point of an oil is above the smoke point. For example, there is a need to retain the soybean oil and remove the ethanol from the mixture. As may be seen, the ethanol has a density and a boiling point that are lower than the density and the boiling point of the soybean oil. Therefore, this separation may be achieved by the evaporator  2120  of the present subject matter. A mixture of soybean oil and ethanol is placed inside the evaporator  2120 , and is heated at a temperature of substantially 78° C. In this temperature the ethanol evaporates while the soybean oil is retained, as desired. Because of the inner structure of the evaporator  2120  of the present subject matter, as described above, during the evaporation of the ethanol, the substantially all the soybean oil accumulates in the lower compartment  2124 , just above the evaporator outlet  125 , when of-course the evaporator outlet  125  is plugged. Once the evaporator outlet is un-plugged, after substantially all the ethanol is evaporated, substantially all of the soybean oil exits the evaporator  2120  and collected. This efficient collection of substantially all the soybean oil may be achieved with the evaporator of the present subject matter. 
     Some embodiments may provide a method for extracting a fatty compound from a biological material. It should be emphasized, again, that the fatty compound may be a single fatty compound or a mixture of multiple fatty compounds. According to some embodiments, the method for extracting a fatty compound from a biological material is performed by using either the extracting apparatus  2002 , or the extracting-storing-distributing apparatus  2001 , as described hereinabove. The method for extracting fatty compounds from a biological material may include mixing a biological material with an alcohol, and obtaining a mixture of the biological material and the alcohol, for extracting the fatty compound from the biological material into the alcohol, and obtaining a mixture of the fatty compound and the alcohol; and evaporating substantially all the alcohol by heating the mixture of the fatty compound and the alcohol at substantially a boiling temperature of the alcohol, while retaining the fatty compound and obtaining an evaporated alcohol. 
     The biological material may be, for example, an entire plant, or at least one part of a plant. For example, the plant may be Maynabis. In another example, the plant may be medical Maynabis. 
     The fatty compound may be, for example, Maynabis fatty compound. For example, the fatty compound may include Maynabidiol (CBD). In another example, the fatty compound may include tetrahydromaynabinol (THC). In another example, the fatty compound may be a mixture of CBD and THC. 
     The alcohol may be, for example, ethanol. In another example, the alcohol may be a mixture of multiple types of alcohol. In another example, the alcohol may be a mixture of multiple types of alcohol of which one type of alcohol is ethanol. 
     According to some embodiments, the method for extracting a fatty compound from a biological material is performed by using either an extracting apparatus  2002 , or an extracting-storing-distributing apparatus  2001 . 
     According to some embodiments, the mixing of the biological material with the alcohol is performed in an extraction chamber  2110  of an extracting apparatus  2002 , or an extracting-storing-distributing apparatus  2001 . 
     According to some embodiments, the evaporating of alcohol is performed in an evaporator  2120  of an extracting apparatus  2002 , or an extracting-storing-distributing apparatus  2001 . 
     When the alcohol is ethanol, the heating of the mixture of the fatty compound and the alcohol is at a temperature range of substantially 70-120° C. According to some embodiments, the heating of the mixture of the fatty compound and the alcohol is at a temperature range of substantially 78-100° C. According to some embodiments, the heating of the mixture of the fatty compound and the alcohol is at substantially a boiling temperature of the alcohol in the mixture. This may be based on the phenomenon that the boiling temperature of an alcohol mixed with oil is higher than the boiling temperature of the alcohol itself. During this method, the mixture of the fatty compound and the alcohol should be heated at the boiling temperature of the alcohol in the mixture. This shift of the boiling temperature of the alcohol with the fatty compound is influenced by a variety of factors, for example the type of fatty compound, the type of alcohol, the relative amount of the alcohol and fatty compound in the mixture, and the like. Therefore, this shift is boiling temperature of the alcohol is unpredictable, but rather should be experimentally determined. This issue of experimentally determining the boiling temperature of the alcohol in a mixture with a fatty compound is under the scope of the present subject matter. 
     According to some embodiments, the method for extracting a fatty compound from a biological material may further include adding a carrier oil (e.g., diluting liquid as described hereinabove). Any type of carrier oil is under the scope of the present subject matter. According to some embodiments, the carrier oil is a neutral oil. That means that the carrier oil has no effects or activities as the fatty compound that is extracted from the biological material. According to some embodiments, the carrier oil is added to the mixture of the fatty compound and the alcohol before the heating of the mixture. According to some embodiments, the carrier oil is added to the mixture of the fatty compound and the alcohol during the heating and the evaporation of the alcohol. According to some embodiments, the carrier oil is added to the fatty compound after substantially all the alcohol is evaporated. 
     According to some embodiments, the method for extracting a fatty compound from a biological material may further include homogenizing the mixture of fatty compound and carrier oil. According to some embodiments, the homogenizing the mixture of fatty compound and carrier oil is by heating the mixture at a homogenization temperature that causes homogenization of the mixture of fatty compound and carrier oil. The homogenization temperature and the heating period are influenced by a variety of factors, and therefore unpredictable, but rather should be experimentally determined. This issue of experimentally determining the homogenization temperature and the heating period for homogenizing the fatty compound and the carrier oil is under the scope of the present subject matter. For example, the aforementioned embodiment of heating at a temperature range of substantially 70-120° C. may be extended beyond complete evaporation of the alcohol in order to homogenize the mixture of the fatty compound with the carrier oil. 
     According to some embodiments, the method for extracting a fatty compound from a biological material may further include recycling of the evaporated alcohol. According to some embodiments, the recycling of the evaporated alcohol includes condensing the evaporated alcohol to a recycled liquid alcohol. According to some embodiments, the recycling of the evaporated alcohol may further include returning the recycled liquid alcohol to the mixture of the biological material and the alcohol. 
     According to some embodiments, the recycling of the evaporated alcohol is performed by an alcohol recycling module  2150  of an extracting apparatus  2002 , or an extracting-storing-distributing apparatus  2001 . According to this embodiment, the recycling of the evaporated alcohol includes: preventing escape of the evaporated alcohol from the evaporator  2120  by covering the evaporating with an evaporator cover  2152 ; collecting the evaporated alcohol through an alcohol vapor outlet  2154  of the evaporator  2120  or the evaporator cover; and passing the evaporated alcohol through a condenser  2156  and obtaining a recycled liquid alcohol. 
     According to some embodiments, the recycling of the evaporated alcohol may further include, after passing the evaporated alcohol through a condenser  2156  and obtaining a recycled liquid alcohol—collecting the recycled liquid alcohol in a recycled alcohol container  2157 . 
     According to some embodiments, the recycling of the evaporated alcohol may further include, after passing the evaporated alcohol through a condenser  2156  and obtaining a recycled liquid alcohol, or after collecting the recycled liquid alcohol in a recycled alcohol container  2157 —directing the recycled liquid alcohol back to the extraction chamber  2110 . 
     The present subject matter further provides a method for storing and distributing a liquid fatty compound. Any type of fatty compound is under the scope of the present subject matter, according to embodiments described herein. As mentioned above, this method is for storing and distributing a liquid fatty compound. The fatty compound may be retained in a liquid phase by keeping the fatty compound in a range of temperatures and pressure level in which the fatty compound is in a liquid state. Preferably, the fatty compound is liquid in ambient temperature and pressure level. 
     According to some embodiments, the method for storing and distributing a liquid fatty compound is performed by using either the storing and distributing apparatus  2003 , or the extracting-storing-distributing apparatus  2001 , of the present subject matter. The method for storing and distributing apparatus  2003  includes: collecting a liquid fatty compound in a fatty compound container  2130 ; and allowing flow of the liquid fatty compound out of the fatty compound container  2130  through a fatty compound outlet. 
     According to some embodiments, the allowing flow of the liquid fatty compound is by using a fatty compound pump  2132 . 
     According to some embodiments, the flow of the liquid fatty compound is continuous. According to some embodiments, the flow of the liquid fatty compound is in doses. According to some embodiments, the doses of the liquid fatty compound are pre-determined. 
     According to some embodiments, the flow of the liquid fatty compound is into a capsule. 
     Some embodiments may provide a method for extracting, storing and distributing a fatty compound from a biological material. This method may be a combination of the previously described method for extracting a fatty compound from a biological material and the method for storing and distributing a liquid fatty compound. 
     According to some embodiments, the method for extracting, storing and distributing a fatty compound from a biological material is performed by the extracting-storing-distributing apparatus  2001 , of the present subject matter. Here are the basic steps of the method for extracting, storing and distributing a fatty compound from a biological material. Other embodiments of this method are described above and are not be repeated. 
     The method for extracting, storing and distributing a fatty compound from a biological material includes: mixing a biological material with an alcohol, and obtaining a mixture of the biological material and the alcohol, for extracting the fatty compound from the biological material into the alcohol, and obtaining a mixture of the fatty compound and the alcohol; evaporating substantially all the alcohol by heating the mixture of the fatty compound and the alcohol at substantially a boiling temperature of the alcohol, while obtaining a fatty compound and an evaporated alcohol; and collecting the liquid fatty compound. 
       FIG. 17A  schematically illustrates, according to an exemplary embodiment, a side cross-section view of a capsule in a resting state. 
       FIG. 17B  schematically illustrates, according to an exemplary embodiment, a side cross-section view of a capsule in an expelling state. 
     According to some embodiments, the capsule  2004  includes a collapsible reservoir  2042  configured to store a liquid and a pressing element  2044  enclosing the collapsible reservoir  2042  and configured to press the collapsible reservoir  2042 . 
     According to some embodiments, the collapsible reservoir  2042  is made of an elastic material that is configured to be compressed when pressed by the pressing element  2044 . The compressing of the collapsible reservoir  2042  exerts pressure on a liquid inside the collapsible reservoir  2042  that pushes the liquid out of the collapsible reservoir  2042  through a capsule outlet  2046 , as described hereinafter. 
     According to some embodiments, the capsule  2004  may further include a capsule outlet  2046  fluidically connected to the collapsible reservoir  2042  and configured to allow exit of a liquid from the collapsible reservoir  2042 , when the collapsible reservoir is compressed. According to some embodiments, the capsule outlet  2046  is part of the collapsible reservoir  2042 , for example in the form of a hole in the collapsible reservoir  2042  that is plugged with a cover (not shown), or a part of the collapsible reservoir  2042  that is configured to be punctured in order to allow exit of a liquid from the collapsible reservoir  2042 . According to some embodiments, the capsule outlet  2046  is a compartment that is fluidically connected to the collapsible reservoir  2042 , as illustrated in  FIGS. 17A and 17B . 
     According to some embodiments, the capsule  2004  may further include a capsule inlet  2048  fluidically connected to the collapsible reservoir  2042  and configured to allow insertion of a liquid into the collapsible reservoir  2042 . According to some embodiments, the capsule inlet  2048  is part of the collapsible reservoir  2042 , for example in the form of a hole in the collapsible reservoir  2042  that is plugged with a cover, or a part of the collapsible reservoir  2042  that is configured to be punctured in order to allow insertion of a liquid from the collapsible reservoir  2042  and then resealed. It should be noted that the aforementioned embodiments of the capsule inlet  2048  should not be considered as limiting the scope of the present invention. Any type of capsule inlet  2048  that is configured to allow insertion of a liquid into the collapsible reservoir  2042  while retaining the intactness of the collapsible reservoir  2042  so liquid will not leak through the capsule inlet  2048 , is under the scope of the present subject matter. 
     As mentioned above, the pressing element  2044  encloses the collapsible reservoir  2042  and is configured to press the collapsible reservoir  2042 . Any type of pressing element  2044  that encloses the collapsible reservoir  2042  and is configured to press the collapsible reservoir  2042 , is under the scope of the present invention. An exemplary pressing element  2044  is illustrated for example in  FIGS. 17A and 17B . According to the embodiment illustrated, for example, in  FIGS. 17A and 17B , the pressing element  2044  includes two arms  2442  connected one to the other, each arm may include a free end  2442 - 1  and a connected end  2442 - 2  that connects to a connected end  2442 - 2  of the other arm  2442 . The orientation of the pressing element  2044  in relation to the collapsible reservoir  2042  is such that the free ends  2442 - 1  of the arms  2442  are at the same side of the capsule outlet  2046  and the connected ends  2442 - 2  of the arms  2442  are distant from the capsule outlet  2046 . As may be seen in  FIGS. 17A and 17B , the connected ends  2442 - 2  of the arms  2442  are adjacent to the capsule inlet  2048 , but this is only an exemplary embodiment, and should not be considered as limiting the scope of the present subject matter. The connected ends  2442 - 2  may be positioned anywhere in relation to the collapsible reservoir  2042 , as long as there are distant from the capsule outlet  2046 . 
       FIG. 17A  illustrates a capsule  2004  in a resting state. In the resting state, the collapsible reservoir  2042  is full with a liquid  2055  and the pressing element  2044  does not press the collapsible reservoir  2042 . For example, the arms  2442  are opened and do not press the collapsible reservoir  2042 . As a result, no pressure is exerted on the collapsible reservoir  2042 , and the liquid  2055  remains in the collapsible reservoir  2042 .  FIG. 7B  illustrates a capsule  2004  in an expelling state. In the expelling state, the pressing element  2044  presses the collapsible reservoir  2042 . For example, the arms  2442  of the pressing element  2044  are now closed, namely pushed one toward the other, and apply pressure on the collapsible reservoir  2042 . As a result, the collapsible reservoir  2042  is squeezed and the liquid  2055  is expelled from the collapsible reservoir  2042  though the capsule outlet  2046 . 
     According to some embodiments, at least one of the arms  2442 , preferably both arm  2442 , includes a finger support  2426  configured to support a finger of a user pressing the arm  2442  and prevent slippage of the finger during pressing. This embodiment prevents slippage of the pressing element  2044 , and the entire capsule  2004 , when it is held and pressed by a user. This embodiment further increases the efficiency of pressing of the pressing element  2044  by the user&#39;s fingers, since the fingers firmly press the arms  2442 . 
     According to some embodiments, the connecting ends  2442 - 2  of the arms  2442  of the pressing element  2044  are pivotally connected. This embodiment improves the movement of the arms  2442  on in relation to the other, since they are able to swivel about an axis. 
     According to some embodiments, the arms  2442  are elastic, and the resting state of the arm  2442  is the default state of the arms  2442 . In other words, when no pressure is applied on the arms  2442 , they are open and the capsule  2004  is in a resting state, as illustrated for example in  FIG. 17A . As long as pressure is applied on the arms  2442 , the arms  2442  are configured to be pressed and the capsule  2004  is in an expelling state. Once the pressure on the arms  2442  is relieved, the arms  2442  open and return to the default state. Any type of mechanism known in the art for rendering the arms  2442  elastic is under the scope of the present subject matter. For example, the arm  2442  may be made of an elastic material. Another example is that an elastic member, for example a spring, is attached to the arms  2442 . 
       FIG. 18A  schematically illustrates, according to an exemplary embodiment, a side cross-section view of a full-expel capsule (e.g., such as capsule  700  described above with respect to  FIG. 7 ) in a resting state. 
       FIG. 18B  schematically illustrates, according to an exemplary embodiment, a side cross-section view of a full-expel capsule in an expelling state. 
     The capsule  2004  illustrated in  FIGS. 17A and 17B  is configured to expel any amount of liquid  2055  from the collapsible reservoir  2042 . On the other hand, the capsule  2004  illustrated in  FIGS. 18A and 18B  is configured to fully expel the liquid  2055  from the collapsible reservoir  2042 . In other word, pressing the collapsible reservoir  2042  with the pressing element  2044  cause expel of the entire content of the collapsible reservoir  2042 , expel of the entire amount of liquid  2055  from the collapsible reservoir  2042 . For this purpose, surfaces of the arms  2442  that are configured to be in contact with the collapsible reservoir  2042  during pressing have a wave-like structure, as illustrated in  FIGS. 18A and 18B . This wave-like structure of the surfaces of the arms  2442  ensures complete squeezing of the collapsible reservoir  2042  and complete expel of the liquid  2055  from the collapsible reservoir  2042 . 
       FIG. 19A  schematically illustrates, according to an exemplary embodiment, a side cross-section view of a doze-expel capsule (e.g., such as capsule  800  described above with respect to  FIG. 9 ) in a resting state. 
       FIG. 19B  schematically illustrates, according to an exemplary embodiment, a side cross-section view of a dose-expel capsule in an expelling state. 
     According to some embodiments, the capsule  2004  is configured to expel doses of a liquid  2055  from the collapsible reservoir  2042 . According to this embodiment, the capsule outlet is a compartment configured to determine the dose of liquid  2055  that is to be expelled. This type of outlet is termed hereinafter “compartment outlet  2047 ”. The compartment outlet  2047  is fluidically connected to the collapsible reservoir  2042 . According to some embodiments, at least one of the arms  2442  includes a compartment pressing element  2427 , at a side of the arm  2442  that is adjacent to the compartment outlet  2047 . In a resting state, illustrated in  FIG. 19A , the arms  2442  do not press the collapsible reservoir  2042  and the compartment outlet  2047  is empty. In the expelling state, illustrated in  FIG. 19B , once the arms  2442  press the collapsible reservoir  2042 , the collapsible reservoir  2042  is slightly squeezed and as a result some liquid  2055  is pushed toward and fill the compartment outlet  2047 . When the arms  2442  further press the collapsible reservoir  2042 , the compartment pressing elements  2427  press the compartment outlet  2047  and in one hand block passage of liquid from the collapsible reservoir  2042  into the compartment outlet  2047 , while on the other hand the compartment outlet  2047  is squeezed and a dose of liquid  2055  is expelled.
