Description:
FIELD 
       [0001]    This invention relates to systems for the domestic and/or non-industrial preparation of cooled edible products, in particular, ice creams, frozen yogurts, sorbets, milkshakes, smoothies etc. 
       BACKGROUND 
       [0002]    In general, preparation of ice cream involves mixing of desired edible ingredients for forming a mixture, adding gas/air into the mixture (sometimes a by-product of the mixing itself) in order to soften the texture of the mixture and cooling of the mixture. 
         [0003]    At present, the majority of ice creams are produced in an industrial process. In this process, ice cream is produced in large volumes and then separated into packages of various sizes and shipped and sold as such to the end users. 
         [0004]    There are also known machines for domestic preparation of ice cream, allowing the user to prepare ice cream from a mixture of edible ingredients of his liking. 
         [0005]    In principle, in such domestic ice cream machines, the user prepares a mix made of ingredients selected by him and introduces the mix into the machine which then cools the mix while mixing. Some machines have a built-in cooling arrangement while others only perform mixing, wherein the user is required to transfer the mix, or the machine itself, into the freezer (or any other cooling chamber). 
       GENERAL DESCRIPTION 
       [0006]    The subject matter of the present application provides a novel system, machines and consumables, for preparation of cooled edible products from their ingredients, e.g. in a portioned amount constituting a defined number of servings which may be 1, 2, 3, etc. One example of such an edible product is ice cream. 
         [0007]    Under the subject matter of the present application, ingredients for production of the cooled edible product are contained in a receptacle (for example in the form of a Pod) which is brought into association with a machine in a manner permitting content of the receptacle (which may be most, or at times the entire content of the receptacle) to be extracted by the machine. The machine is then operated to produce the edible product. 
         [0008]    The receptacle carries data that is indicative of process parameters to be applied by the machine to prepare said product. The data is formatted so as to permit reading by a data reader in the machine. The data may be embedded in an optically-readable data label, e.g. a barcode, or may be embedded in an electromagnetic element such as an RFID element. Once the receptacle is brought into association with the machine, content thereof is extracted and the data is read by the data reader. Such data, once read, is fed into a controller of the machine that induces the machine to operate in a manner applying said process parameters to the processing of the edible ingredients to thereby obtain the cooled edible product. 
         [0009]    The cooled edible product is a product that when consumed has a solid or semi-solid consistency, such as ice creams, frozen yogurts, sorbets, milkshakes, smoothies etc. 
         [0010]    According to one aspect of the subject matter of the present application, there is provided a system for the preparation of a cooled edible product from ingredients, said system comprising:
       a receptacle holding at least some of the ingredients, and a processor for processing the ingredients and producing the cooled edible product therefrom, the processor comprising or being associated with a data reader;   the receptacle being configured for association with the processor in a manner permitting the majority of the content of the receptacle to be extracted by the processor;   the receptacle carrying data indicative of process parameters specific for said processing, the data being formatted in a manner permitting its identification by the data reader to thereby induce the processor to apply said process parameters to said processing.       
 
         [0014]    The processing arrangement of said machine can comprise a mixing chamber configured for mixing the edible ingredients contained within the receptacle to form a pre-cooled mixture. In particular, the mixing chamber can be configured for receiving therein at least one additional ingredient from a source other than the receptacle. 
         [0015]    The processing arrangement can also comprise an aeration arrangement configured for introducing gas into a given mixture to form an aerated mixture, and a cooling arrangement configured for reducing the temperature of a mixture contained therein to provide a cooled mixture. However, it is appreciated that the aeration of the mixture can also be performed as part of the mixing process in the mixing chamber, i.e. by mixing the ingredients, the mix is naturally aerated. 
         [0016]    The cooling arrangement may comprise a cooling chamber adapted for receiving the mixed ingredients and holding them for a time sufficient for them to cool. The cooling chamber may also, by one embodiment, serve as a mixing chamber and be provided with at least one rotating element configured for agitating, shearing and/or mixing the ingredients during cooling, as well as scraping off material from the inner walls of this combined cooling and mixing chamber. 
         [0017]    The rotating element can be constituted by, for example, a dasher, an auger and/or a combination thereof. Respectively, the ingress and egress directions of material into and out of the cooling chamber can vary. For example, in case of an auger, the ingredients ingress into the cooling chamber at one end of a longitudinal axis of the auger, be progressed therealong and discharged at the other end. By another embodiment, the cooling chamber or a combined cooling and mixing chamber, has a single opening serving for both ingress of the ingredients and egress of the cooled edible product. 
         [0018]    The machine can also be provided with a defrosting arrangement disposed between the mixing chamber and the cooling chamber, and configured for preventing the passageway between the chambers from being clogged due to freezing (as one side of the passageway is opened to the cooling chamber). 
         [0019]    In accordance with a particular example, the defrosting arrangement can comprise a heat source associated with the passageway and configured for heating thereof. 
         [0020]    In addition, the machine can also comprise a discharge arrangement configured for evacuating any residual material contained in the passageway between the mixing chamber and the cooling chamber, during or following the production of the cooled edible product. This can allow the machine to operate continuously without requiring any disassembling thereof between production sequences. 
         [0021]    In addition, the machine can be configured so as not to begin a new production sequence before the passageway between the mixing chamber and the cooling chamber is properly cleared of the cooled edible product prepared during a previous sequence. 
         [0022]    The machine may be formed with an outlet configured for dispensing the cooled edible product. The outlet may be adapted to receive and hold a patterning element, configured for providing the edible product discharged through the outlet opening with a particular shape and/or pattern. 
         [0023]    In particular, a patterning element can be in the form of a perforated disc, so that when the edible product is pressed through the perforation(s) it assumes a cross-sectional shape which is that of the perforation(s). 
         [0024]    The process parameters can be any parameter of an operation constituting part of the preparation of the cooled edible product and affecting its final characteristics. For example, the process parameters can be at least one of the following:
       mixing time of the at least one ingredient;   quantity of an additional ingredient;   introduction time of an additional ingredient;   aeration time of a mixture of the at least one ingredient;   amount of gas introduced into a mixture of the at least one ingredient during its aeration time;   cooling time of an aerated mixture of the at least one ingredient;   revolution velocity of the dasher of the cooling chamber;   temperature reduction of an aerated mixture of the at least one ingredient;   pressure within the mixing and cooling chambers;   diameter of an outlet through which said edible product is provided;   provision rate of said edible product through an outlet;   size of the valve opening between the mixing chamber and the cooling chamber;   opening frequency/time of the valve opening between the mixing chamber and the cooling chamber.       
 
         [0038]    The arrangement can be such that said process parameters are configured for determining processing of the at least one edible ingredients after its extraction from said receptacle. In other words, the process parameters relate to all steps of preparation of the cooled edible products, not only operations taking place within the receptacle. 
         [0039]    The controller can also be configured for controlling the valve opening between the mixing chamber and the cooling chamber, for example, for providing a gradually increasing/decreasing opening diameter thereof. Such control may allow optimizing the preparation process of the cooled edible product. 
         [0040]    In addition, the controller can be configured for regulating operation of the dasher of the mixing chamber, e.g. by providing a variable revolution speed during the preparation process depending on various stages. 
         [0041]    The controller can also be programmed to alert the user regarding required cleaning of the machine and to prevent use of the machine if such cleaning is not performed. This can happen under various circumstances, non-limiting examples of which are:
       a predetermined amount of time has passed without proper cleaning of the machine;   residual ingredients are left within the machine, in particular within the passageway leading from the mixing chamber to the cooling chamber;   the controller does not receive an indication regarding parameters pointing to a successful emptying of the cooled edible product from the machine at the end of a previous manufacturing sequence;   different types of cooled edible products are attempted to be prepared successively, e.g. sorbet following yogurt.       
 
         [0046]    In all of the above cases, the controller can prevent the machine from preparing the cooled edible product and alert the user that a cleaning process should be performed before performing another preparation sequence. 
         [0047]    Per the above, the controller can be programmed to monitor different parameters of operation of the machine, for example, the last time of use, type of edible products prepared etc. The controller can also be fitted with a memory unit for storing the required data and providing statistics based thereon. 
         [0048]    In addition, the controller can be provided with the ability to download data for maintenance purposes, for example, firmware updates from the manufacturer website. 
         [0049]    The process parameters may also include other elements such as, for example, configuring the machine so that unless mixing was properly performed and accomplished and/or unless the outlet opening was properly opened for a predetermined amount of time, the machine will not allow use of another receptacle. Another example is a control of the revolution speed of the mixing element upon discharge of the edible product from the machine, as well as the amount of time in which the outlet is opened for such discharge. 
         [0050]    Typically, the operation of the machine is so that one or both of the following is prevented:
       mixing of ingredients from different receptacles; and   ingredients from previous run of the machine remaining within the cooling and/or mixing chamber before a new run of the machine.       
 
         [0053]    The receptacle can be in the form of a pod, and can be configured for forming, once received in the machine, a functional component in addition to being the carrier and source of said ingredients. For example, once in situ in the machine the pod may define at least part of the mixing chamber. In this case, mixing of the edible ingredients may take place, at least partially, within the pod itself. 
         [0054]    Alternatively, according to another example, said receptacle can be configured for being externally associated with said machine, i.e. with the majority of the receptacle protruding from the machine. 
         [0055]    Nonetheless, in both of the above examples, said receptacle can be configured for mixing therein of the at least one edible ingredients. 
         [0056]    According to a specific design, the pod can be constituted by a pod assembly and comprise at least a first receptacle and at least a second receptacle, each containing a different ingredient for producing the cooled edible product. 
         [0057]    The arrangement can be such that each pod assembly is part of a type of desired cooled edible product, for example, pod assemblies configured for producing sorbets, pod assemblies configured for producing frozen yogurts etc. 
         [0058]    Per the above, it could be possible, for example, for an individual to obtain a first type receptacle, and attach thereto a variety of second receptacles of the same type and vise versa. In particular, an individual can equip a first, sorbet type receptacle containing the solid ingredients for producing the sorbet (for example) with a plurality of second, sorbet type receptacles containing a variety of fluid ingredients, e.g. juices of different flavors, and so produce a variety of sorbets. 
         [0059]    However, it is appreciated that the first receptacle and the second receptacle can be sold/provided independently. It is noted that although the receptacles can be mixed and matched, assembling the right types of first and second receptacles can be required in order to obtain an optimal quality of the cooled edible product. 
         [0060]    In order to prevent mismatch between different types of pod assemblies, a first receptacle of one type can only be assembled/attached to a second receptacle of the same type (e.g. a first, sorbet receptacle can only be attached to a second, sorbet receptacle but not to a second, frozen yogurt receptacle). 
         [0061]    By an embodiment of the current disclosure, the receptacle can be provided as part of an assembly that includes also an element configured for receiving the edible product produced by the machine, whereupon the edible product may be consumed directly therefrom. Thus, the assembly constitutes a complete set, comprising a receptacle providing the ingredient and an element for receiving and for eating the edible product out of. 
         [0062]    In accordance with another embodiment, the receptacle itself has a dual function: as a carrier of the ingredients and subsequently as a receptacle for finished edible product. Thus, the receptacle may thus be extracted from the machine and thereafter be used as a receptacle for the edible product. 
         [0063]    By one embodiment the machine is configured for revolving said receptacle, thereby allowing mixing of the material contained therein. According to another embodiment, the machine comprises a mixing member configured for mixing said at least one edible ingredient within the receptacle. 
         [0064]    The machine can further comprise an arrangement configured for the provision of at least one additional edible ingredients into said mixing chamber to be mixed with the at least one ingredient contained within said receptacle. 
         [0065]    By an embodiment of the current disclosure, the machine can be configured for simultaneously receiving therein more than one receptacle, for producing cooled edible products from a mixture of ingredients provided by the more than one receptacle. Furthermore, the arrangement can be such that the ingredients of some pods are provided to the mixing chamber while ingredients of the remaining pods are provided directly to the cooling chamber or directly to the outlet port. 
         [0066]    It is appreciated that under the above example, the machine can comprise a plurality of readers, each being configured for obtaining the data provided by its respective pod. The controller can be configured for integrating the data received from various pods in order to determine the process parameters for preparation of the edible product from the different pods. 
         [0067]    Furthermore, according to a particular example, the machine can be formed with different ports, each being configured for receiving therein pods of different designs, each pod carrying a different set of ingredients and configured for contributing to the production of the cooled edible product. 
         [0068]    In particular, by the embodiment of the previous paragraphs, at least the following combinations are made possible:
       a first pod containing edible ingredients and a second pod containing fluids. For example, the first pod can contain the ingredients for producing chocolate ice cream (e.g. sugar, cocoa and functional ingredients) while the second pod can contain a flavored fluid (e.g. orange juice), thereby producing orange flavored chocolate ice cream;   a first pod containing edible ingredients and a second pod containing a topping of some sort, e.g. sprinkles, chocolate chips etc.;   several pods containing different ingredients for producing an enlarged dose of ice cream having a mixed flavor; and   a plurality of pods, each containing ingredients for the production of the edible product, allowing successively producing of consecutive portions of the edible product without re-charging the machine with a pod after every batch.       
 
         [0073]    In general, the machine can be provided with a data reader, a controller and a drive motor, such that the data reader is configured for obtaining the data provided on the receptacle and transfer it to the controller, and the controller is configured for using this data for controlling the operation of the drive motor operating the various arrangements of the machine. 
         [0074]    It is also appreciated that the controller can be configured for controlling any other of the machine&#39;s components and functions, e.g. the cooling chamber, provision of fluids, operation of the valve/s etc. 
         [0075]    The data reader of said machine and the data provided on said receptacle can be, for example, at least one of the following:
       a barcode scanner and a barcode;   an RFID reader and an RFID tag;   an optical scanner and a graphic pattern;   a magnetic strip and a magnetic reader;   depressible elements and a pattern of bulges for depressing said depressible elements.       
 
         [0081]    The controller can also be responsible for handling malfunctions and tech-support of the machine. In particular, in the event of a malfunction, the controller can be configured to output a malfunction code which can be provided to a service company. The malfunction code can either be provided to the company by the user or automatically by the machine, allowing the service company to form a record regarding repeating malfunctions etc. 
         [0082]    Furthermore, the data transferred between the pod and the controller can also comprise authentication information regarding the pod (e.g. indication of a genuine pod or a ‘third party’ pod). Authentication can be performed, for example, by a serial number associated with the pod, optionally including some mathematical algorithm applied to the serial number. This also facilitates preventing re-use of the same pod and/or serial number/code twice within the same machine. 
         [0083]    In addition, the data can also include information regarding the expiration date of the ingredients within the pod, preventing the use of pods, the date of ingredients of which has already expired. This feature can also be particularly useful for facilitating constant replacement of series of receptacles and complementary authentication codes, thereby preventing a third party from using the authentication codes of old receptacle series (not sold anymore on the market). 
         [0084]    In addition, the machine can also comprise a mechanism configured for deforming the used receptacle/pod/capsule after use thereof, e.g. crushing or compressing it. Such a mechanism may allow for a more compact waste volume of the used capsules as well as for preventing re-use of the pod itself. 
         [0085]    In accordance with a particular design of the above described system, it can furthermore comprise a complementary cooling arrangement configured for accelerating the cooling process taking place in the cooling chamber. 
         [0086]    In particular, the complementary cooling arrangement can be provided with a cooling fluid at below-zero temperature configured for either mixing with the ingredients of the receptacle within the mixing chamber and/or cooling chamber or coming into contact with an external surface of the mixing chamber and/or cooling chamber in order to facilitate cooling. 
         [0087]    The cooling fluid can be a solid (e.g. CO 2  in solid form at about 80° C. below zero), a fluid (e.g. liquid Nitrogen at 180° C. below zero, liquid Oxygen at 220° C. below zero) or even a gas. 
         [0088]    According to one example, the cooling arrangement can comprise a cooling port configured for receiving therein a pod containing a pre-determined amount of cooling fluid, commensurate to the portioned amount of cooled edible product to be prepared using the machine. However, it is appreciated that the cooling arrangement can alternatively comprise a receptacle configured for containing the cooling fluid and distributing a required amount of cooling fluid during the manufacturing process of the cooled edible product. 
         [0089]    Per the above, the complementary cooling arrangement can provide the option for expedited preparation (also referred herein a ‘turbo mode’) of the cooled edible product, requiring considerably less time than when using the cooling chamber in its own. 
         [0090]    According to another aspect of this disclosure there is provided an appliance for the preparation of a cooled edible product, said appliance comprising a processor for processing the ingredients and producing the cooled edible product therefrom; the processor comprising or being associated with a data reader; said machine being further configured for association with a receptacle containing one or more of the edible ingredients to be processed and carrying data indicative of process parameters specific for said processing, the data being formatted in a manner permitting its identification by the data reader to thereby induce the processor to apply said process parameters to said processing. 
         [0091]    The appliance can further be configured for receiving a cleaning receptacle containing at least one cleaning agent and for the initiation of a cleaning sequence for cleaning the appliance. The cleaning receptacle contains cleaning agents and typically carries a data unit indicative of process parameters to be applied by the appliance for cleaning. 
         [0092]    In particular, the cleaning receptacle can comprise a data unit containing data associated with predetermined process parameters for the cleaning of the appliance. However, it should also be appreciated that a cleaning pod can be provided with data indicative of process parameters which are unique for a cleaning process and differ from the process parameters required for the preparation of cooled edible products. 
         [0093]    The appliance can be configured to use the cleaning receptacle in order to rinse elements of the appliance, e.g. mixing chamber, cooling chamber etc. The fluid used for rinsing the components can be discharged from the appliance to the outside environment (for example into an external receptacle). Alternatively, the appliance can be configured with proper conduits allowing the discharge of rinsing fluids directly into a drainage system (for example to a drain pipe of a sink). 
         [0094]    In addition, the appliance can comprise a rinsing arrangement configured for providing the appliance with heated rinsing fluid during a cleaning process using the cleaning receptacle. According to one example, the rinsing arrangement can be configured for connection to a water supply network external to the appliance. Alternatively, according to another example, the rinsing arrangement can comprise as a rinsing chamber containing therein rinsing fluid and means for heating thereof prior to its provision to the appliance. 
         [0095]    It is noted that the rinsing fluid does not have to include any detergents or cleaning agents and can simply be constituted by water. As previously described, the appliance can be configured for receiving therein a cleaning receptacle containing the required detergents and configured for operating in conjunction with the rinsing fluid. 
         [0096]    The rinsing arrangement can also comprise at least one cleaning nozzle configured for providing a directional jet of rinsing fluid to various components of the appliance, for example, the valve between the mixing chamber and the cooling chamber, and the outlet opening in order to rinse therefrom any residual ingredients or leftovers of the cooled edible product. 
         [0097]    According to another aspect of the subject matter of the present application there is provided a receptacle containing at least one edible ingredient for the preparation of a cooled edible product by applying process parameters, and carrying data indicative of the process parameters, said data being readable by a data reader of a processor that can be configured for applying said process parameters to said ingredients. 
         [0098]    According to a further aspect of the subject matter of the present application there is provided a system for the preparation of a cooled edible product from ingredients, said system comprising a receptacle holding at least some of the ingredients, and a processor for processing the ingredients and producing the cooled edible product therefrom, the processor comprising or being associated with a data reader; the receptacle being configured for association with the processor in a manner permitting at least some of the content of the receptacle to be extracted by the processor; the receptacle carrying data indicative of process parameters specific for said processing, the data being formatted in a manner permitting its identification by the data reader to thereby induce the processor to apply said process parameters to said ingredients during processing also after being extracted from the receptacle. 
         [0099]    According to still another aspect of the subject matter of the present application there is provided a system for the preparation of a cooled edible product from ingredients, said system comprising a receptacle holding at least some of the ingredients, and a machine for processing the ingredients and producing the cooled edible product therefrom, the receptacle being configured for association with the machine in a manner permitting at least some of the content of the receptacle to be extracted by the machine; wherein the receptacle carries data indicative of process parameters specific for said processing, the data being formatted in a manner permitting its identification by a designated data reader of the machine to thereby induce the machine to apply said process parameters to said processing; and wherein said processing includes processing the edible ingredients after their extraction from said receptacle. 
         [0100]    A further aspect of the subject matter of the present application is directed to a system for the preparation of a cooled edible product from ingredients, said system comprising a receptacle holding at least some of the ingredients, and a processor for processing the ingredients and producing the cooled edible product therefrom; the processor comprises a receptacle port for matchingly receiving therein the receptacle in a manner permitting at least some of the content of the receptacle to be extracted by the processor; the processor being configured for processing the edible ingredients after their extraction from said receptacle 
         [0101]    In accordance with a further aspect of the disclosed subject matter, there is provided a temperature regulation module configured for being interposed between a liquid source and a home appliance making use of said fluid, said temperature regulation module being configured for receiving liquid from the liquid source, regulating its temperature and transferring into the appliance, said module comprises a controller in communication with a controller of the appliance, so that control of the temperature is performed in accordance with data provided by the controller of the machine. 
         [0102]    The above temperature regulation module can also be used in conjunction with additional devices requiring provision thereto of a fluid at a certain temperature, e.g. espresso machines, coffee machines, percolators, water bars), wherein it is configured for communicating with the controller of such devices in order to determine the temperature of the fluid based on data therefrom. 
         [0103]    In addition, the temperature regulation module can also be configured for providing the heated/cooled fluid directly to the user for such purposes as preparing hot beverages, baby bottles etc. 
         [0104]    It should be appreciated that modern kitchens are equipped with a plurality of devices, each being provided with its own heating/cooling module and a corresponding controller. In accordance with the above aspect, the temperature regulating module can be configured for servicing any such device, thereby eliminating the need for an individual heating/cooling module in each of the devices. 
         [0105]    The temperature regulating module can be provided with a fluid inlet port and at least one fluid outlet port which can be selectively coupled to a device of the user&#39;s choosing. The module can further comprise a valve configured for directing the fluid into a specific outlet port in accordance with the controller.

     DETAILED DESCRIPTION OF EMBODIMENTS 
       [0134]    Attention is first drawn to  FIG. 1 , in which a system for the domestic preparation of a cooled edible product (e.g. ice cream) is shown, generally designated as  1 . The system  1  comprises a housing  10 , a mixing module  20 , and cooling module  30 , both modules  20 ,  30  being contained within the housing  10 . The system  1  further comprises a pod  40  (shown in  FIG. 3 ) containing at least one ingredient of the cooled edible product, the pod  40  configured for being received within the housing  10 . 
         [0135]    The housing  10  also comprises a cooling arrangement  12  configured for removing heat from the cooling module  30 , and a drive motor  14  configured for driving ingredients of both the mixing module  20  and the cooling module  30 . It is appreciated that individual motors can be provided for each of the mixing module, cooling module etc. 
         [0136]    The housing  10  further comprises a cover  17  located over an inlet  21  of the mixing module, a user fluid inlet  15  and a built-in fluid inlet  16 , both inlets  15 ,  16  leading to the mixing module  20 . 
         [0137]    With additional reference being made to  FIG. 2 , the mixing module  20  is formed with a cavity  22  configured for receiving therein a pod  40  (shown in  FIG. 3 ) via the inlet  21 . The mixing module  20  further comprises a valve  24  configured for selectively allowing/preventing fluid communication between the mixing module  20  and the cooling module  30 . 
         [0138]    It is appreciated that the arrangement can be such that the pod  40  comprises the valve itself while the machine is formed with a corresponding engagement port configured for operating the valve. 
         [0139]    The mixing module  20  also comprises a mixing arrangement (not shown) powered by the drive unit  14  and configured for revolving the pod  40  about a central axis X 1  thereof in order to allow mixing of the substance contained therein. 
         [0140]    The cooling module comprises a chamber  31  having a main cavity fitted with a dasher having a central shaft  32  and mixing elements  34 . The shaft  32  and mixing elements  34  are configured for revolving about the axis X 2  of the shaft in order to provide further mixing of the substance contained therein. 
         [0141]    The chamber  31  is cooled by the cooling arrangement  12  so that the substance contained within the cooling module  30  and coming in contact with the wall of the chamber  31  is reduced in temperature. In this connection, it is important to note that the mixing element  34  are also configured for scraping off portions of the mixture which stick to the inner wall of the chamber  31 , as they freeze. 
         [0142]    The cooling module  30  also comprises an outlet port  36  configured for providing the cooled edible product to the user of the system  1 . 
         [0143]    The operation of the cooling arrangement  12  and the drive motor  14  is configured for being controlled by a controller  18 . The controller can be further configured for receiving data signals from a transmit-unit  19  associated with the mixing module  20 , and issuing corresponding commands to the cooling arrangement  12  and the drive motor  14 . 
         [0144]    Turning now to  FIG. 3 , a basic design of a pod  40  is shown, comprising a body  42  with a central cavity  41 , an outlet port  44  and inner side winglets  46  and top winglet  48 , configured for mixing the ingredients contained within the pod  40 . 
         [0145]    In addition, the pod  40  comprises a data unit  49  which is configured for providing the system  1  with data regarding preparation parameters of the cooled edible product. The parameters in the data unit  49  are specific for the edible substance contained within the pod  40  and its state (solid, slurry, fluid etc.). 
         [0146]    The data unit  49  is configured for communication with the transmit-unit  19  of the housing  10  in order to provide it with the necessary parameters which can then be transmitted to the controller  18 . 
         [0147]    Reference is now made to  FIG. 5 , in which the outlet port  44  can be formed with a thread  45  configured for secure attachment of the pod  40  to the mixing chamber  20 , which is, in turn, formed with a corresponding threaded portion. 
         [0148]    With particular reference to  FIG. 5 , the pod  40  illustrates a “wet-pod”, i.e. a pod comprising an edible substance which is mixed with fluid, so that at least the majority (if not all) of the ingredients required for the preparation of the edible product are already contained within the pod  40 . In this case, the pod can be inserted into the mixing module  20  and no additional fluid may be required for producing the cooled edible product. 
         [0149]    Alternatively, with reference to  FIG. 4 , the pod  40 ′ can be a “dry-pod”, only containing some of the edible ingredients for the preparation of the edible product. In this case, the user can be provided with an additional member  50 , configured for providing the “dry-pod”  40 ′ with the required fluids for the preparation of the edible product. In particular, the user can fill the additional member  50  with a desired fluid of his/her choice and then attach the additional member  50  to the dry-pod  40 ′, thereby forming a pod assembly similar to that of the pod  40 . 
         [0150]    The dry-pod  40 ′ and the portion  50  can be configured for engagement with one another via a thread  47 ′,  55 , but it is appreciated that various means of connection therebetween can be provided, not limited to threading. In case of the dry-pod  40 ′, the pod  40 ′ resembles a capsule (similar to that which can be found in coffee machines). 
         [0151]    With reference to  FIGS. 6 and 7 , another embodiment of the machine is shown in which the dry-pod  40 ′ is configured for insertion into the machine (without an additional member  50 ), similar to a pod for a coffee machine. In this case, the required fluids are provided directly into the mixing chamber  20  of the machine to be mixed with the substance of the dry-pod  40 ′. 
         [0152]    In particular,  FIGS. 6 and 7  demonstrate two configurations of insertion of the pod  40 ′ into the machine, one from the side ( FIG. 6 ) and one from the top ( FIG. 7 ). 
         [0153]    In both the wet-pod  40  and the dry-pod  40 ′, the arrangement is such that the pod  40 ,  40 ′ is configured for constituting a part of the mixing cavity  22 . 
         [0154]    In addition, regardless of which pod is used, fluid can be provided to the mixing cavity  22  either manually by the user via opening  15  or via a built-in inlet  16  which can be connected to the domestic water supply, bottle-port, etc. 
         [0155]    In operation, the pod  40 ,  40 ′ is first inserted into the mixing chamber  20 . Once inserted, the data unit  49  provides the transmit unit  19  with the necessary preparation parameters which are then transmitted to the controller  18 . 
         [0156]    The processing parameters can be either one of a variety of parameters, for example:
       mixing time of the at least one ingredient;   quantity of an additional ingredient;   introduction time of an additional ingredient;   aeration time of a mixture of the at least one ingredient;   amount of gas introduced into a mixture of the at least one ingredient during its aeration time;   cooling time of an aerated mixture of the at least one ingredient;   temperature reduction of an aerated mixture of the at least one ingredient;   diameter of an outlet through which said edible product is provided; and   provision rate of said edible product through an outlet.       
 
         [0166]    Once the process parameters are acquired by the controller  18 , preparation of the cooled edible product can commence. 
         [0167]    The controller  18  first determines whether or not an additional fluid is required, and in the positive, either alerts the operator of the machine to add the fluid via the inlet  15  or automatically provides it via the inlet  16 . 
         [0168]    Once all the ingredients are contained within the mixing chamber  20 , the drive unit  14 , controlled by the controller  18 , begins its operation and the edible ingredients are mixed together to form a mix. The mixing time, mixing rate etc. are all determined by the process parameters previously provided to the controller  18 . 
         [0169]    Once the ingredients are properly mixed within the mixing module  20 , the controller  18  operates the valve  24  in order to allow the mix to flow into the mixing chamber  31  of the cooling arrangement  30 . 
         [0170]    The mix is then aerated and cooled to the necessary temperature (also determined based on the process parameters) and once it reaches a desired temperature/pressure/texture etc., the cooled edible product can be delivered to the user via the opening  36 . 
         [0171]    It is appreciated that for different types of ice cream, different process parameters are required in order to properly accentuate the flavors of that particular ice cream type, including texture, temperature sensation on the tongue and palate, stability of the ice cream before melting etc. 
         [0172]    Several examples are provided below:
       when making chocolate ice cream having a high sugar/dextrose level, it may be desired that the ingredients are cooled for a longer duration of time; The same may hold true for the preparation of a sorbet with an alcoholic substance; and   when making a nut ice cream with a high fat percent, it may be desired to reduce the revolution speed of the dasher.       
 
         [0175]    In addition:
       A “wet-pod” will normally require a shorter/slower mixing process, then a “dry-pod” which content is mixed with additional materials.   A product based on a mix calculated for a low freezing point, may require a longer cooling process and or a higher level of temperature reduction.   A product based on a high level of solids, and planned for a low level of over-run, may require slower turning of the dasher and or a longer process.       
 
         [0179]    With reference being made to  FIGS. 8 to 11 , the opening  36  can be of various configurations, for example, in the case of  FIGS. 8 and 9  to tilt about a pivot point and in case of  FIGS. 10 and 11 , to slide up and down. 
         [0180]    It is noted that the cooling module  30  comprises a mixing arrangement (shaft  32  and elements  34 ) which is configured so as to propel the product towards the opening  36 . So long as the opening is closed, pressure is applied to the edible product and, when a desired pressure is reached (also determined by the process parameters), the controller can signal the outlet  36  to open. 
         [0181]    With reference to  FIGS. 12 and 13 , provision of the cooled edible product to the user can be made either solely by pressure applied on the product by the mixing shaft  32  and elements  34 . In particular, the shaft  32  and elements  34  can be configured for propelling the edible product towards the opening as indicated by arrow  37 . In addition, in case the chamber  31  is slightly tilted ( FIG. 13 ) to use gravitational forces to let the product come out. 
         [0182]    It may be desired to clean the system  1  and/or rinse it between the preparation of different types of cooled edible products. For this purpose, there can be provided a cleaning pod (not shown) having a shape similar to that of the pod  40 ,  40 ′, and containing a cleaning agent which is configured to flow through the system  1  (similar to the edible ingredients and product) when the pod is connected to the machine. 
         [0183]    Turning now to  FIGS. 14A and 14B , another design of a system for the preparation of a cooled edible product is shown, generally designated as  101 , and comprising, similar to the previously described system  1 , a main housing  110  accommodating therein a mixing chamber  120 , a cooling chamber  130 , a drive motor  115 , a reader  118  and a controller  116 . 
         [0184]    The housing  110  is provided with a dispenser opening  136  configured for providing the cooled edible product (once prepared), a base  138  configured for positioning thereon a receptacle for receiving therein the cooled edible product dispensed from the opening  136  and a handle  111  for operating the system  101 . 
         [0185]    In operation, a receptacle portion  144  of a pod  140  (see  FIGS. 15A ,  15 B) is provided through a top opening  113  of the housing into the mixing chamber  120  and positioned so as to be aligned with the position of the reader  118 . The reader  118  is then configured for obtaining from the pod the required process parameters for the preparation of the cooled edible product, and provide the same to the controller  116 . 
         [0186]    Once all the required information is obtained by the controller  116 , the latter can regulate operation of the mixing chamber  120 , cooling chamber  130  and drive motor  115  for producing the edible product. 
         [0187]    When the edible product is ready, the operator of the machine can be prompted by the system  101  (either by a visual or auditory aid) to operate the handle  111  of the system  101  in order to open the dispensing opening and allow the cooled edible product to be dispensed therefrom into a designated receptacle (not shown) placed on the base  138 . 
         [0188]    As appreciated from above, since the entire information regarding process parameters is provided by the pod itself, the entire system  101  can include a single handle (and possibly an on/off button) required for operating it, making the system  101  extremely simple and user friendly. 
         [0189]    Turning now to  FIGS. 15A and 15B , a ‘wet pod’ is shown generally being designated as  140 , and comprising a receptacle portion  144  and a cap  142 . The receptacle portion  144  is formed with a cavity  141  configured for containing therein ingredients for the production of the cooled edible products and a mixing port  146  configured for operating in conjunction with the mixing chamber  120 . The cap  142  is formed with a cavity configured for accommodating, almost fully, the receptacle portion  144 . 
         [0190]    It is appreciated that the term ‘wet pod’ refers to a receptacle which does not necessarily require the addition of a fluid to its contained ingredients in order to produce the cooled edible product. In other words, the wet pod can contain therein all the required ingredients for producing the cooled edible product, without requiring any additional ingredients. 
         [0191]    In operation, the cap  142  of the pod can be removed before its insertion into the housing  110 , and be placed on the base  138  to be used as the receptacle configured for receiving therein the cooled edible product. It is also appreciated that while the volume of the cap  142  is smaller than that of the receptacle portion  144 , it is still appropriately sized for receiving therein the cooled edible product, similar to an ice cream cup/cone which normally accommodates a greater amount of ice cream than its volume. 
         [0192]    With reference to  FIG. 16 , another design of a ‘dry pod’ is shown, generally designated as  140 , which is configured, contrary to the ‘wet pod’, for containing therein only some of the ingredients for the preparation of the cooled edible products, and required the addition of a fluid and/or further ingredients. On the other hand, the use of a ‘dry pod’ allows reducing the overall volume of the pod. 
         [0193]    Attention is now turned to  FIGS. 18A to 18D , in which another example of the machine is shown, generally being designated as  200 . As in previous examples, the machine  200  includes a housing  210  accommodating therein a mixing chamber  220  configured for receiving therein a pod  240 ,  240 ′ containing at least some ingredients for the preparation of the chilled edible product, a cooling chamber  230  for cooling the edible product/ingredients and a compressor  214 . 
         [0194]    The machine  200  is further provided with a dispensing opening  236  configured for dispensing of the chilled edible product to a user of the machine and a receptacle tray  238  for positioning thereon a receptacle for the chilled edible product. Control over dispensing is performed using a utility handle  211  articulated to the dispensing opening. 
         [0195]    With particular reference to  FIG. 18C , the mixing chamber  220  has a cavity  222  configured for receiving therein the pod  240  and is fitted with data reader  219  configured for receiving data from a data source  249  of the pod  240  and transmit the data to the control unit  218 . 
         [0196]    Reference is now made to  FIG. 18D  in which a cross-section of the machine  200  is shown. It is observed that the mixing chamber  220  comprises at the bottom end thereof a piercing element  228  configured for puncturing a closure of the pod  240  when received within the mixing chamber  220  (see also  FIGS. 19A to 20B ), to allow extraction of the ingredients from the pod into the cooling chamber  230  after mixing takes place in the mixing chamber  220 . For this purpose, the piercing element  228  is of a tapering shape ending with a tip sharp enough to pierce the closure. 
         [0197]    The piercing element  228  is mounted on a rotor plate  224  configured for revolving the pod  240  and/or mixing the ingredients therein. It is also noted that the piercing element  228  is designed to be wide enough to assist in the mixing of the ingredients contained within the pod  240  during the mixing stage. Mixing is further facilitated by winglets  246  formed within the receptacle  240 . 
         [0198]    The passageway between the mixing chamber  220  and the cooling chamber  230  is provided with a valve  229  configured for regulating passage of mixed ingredients between the chambers  220 ,  230 . The valve  229  is also associated with the controller  218  and the operation of which is regulated thereby. 
         [0199]    As in previous examples, the cooling chamber  230  comprises a mixing motor and a mixing element  234 , and is slightly inclined towards the outlet nozzle  236  so as to utilize gravitational forces in dispensing of the cooled edible product. In addition, the cooling chamber  230  is provided with a valve  239  configured for regulating dispensing of the cooled edible product therefrom. In particular, the valve can be configured for preventing emission of the cooled edible product from the cooling chamber  230  before it is fully ready. 
         [0200]    Turning now to  FIGS. 19A and 19B , an integral pod  240  is shown being in the form of a receptacle  242  defining therein a cavity for containing the required ingredients for producing the cooled edible product. 
         [0201]    The receptacle  242  is formed with a threaded attachment port  245  and has an opening sealed by a foil closure  244 . When the pod  240  is received within the mixing chamber  220  of the machine  200  (see  FIG. 18D ), the piercing element  228  is configured for puncturing the foil, allowing the ingredients to be received within the mixing chamber  220 . 
         [0202]    It is appreciated that the mixing of the ingredients within the mixing chamber  220  actually takes place within the pod  240 , as the pod is sized and shaped to be precisely received within the mixing chamber  220 . It is noted here that the mixing chamber  220  is only configured, in the example, for operating in conjunction with a genuine pod  240  of the machine. 
         [0203]    The pod  240  has fitted thereto and/or integrally formed therewith a data label  249  configured for communicating with the data reader  219  of the machine  200 , for providing the controller  218  with the required information for producing the cooled edible products. 
         [0204]    With attention being turned now to  FIGS. 20A and 20B , a pod assembly  240 ′ is shown comprising a first receptacle  242 ′ and a second receptacle  252 ′, being configured for attachment to one another. The receptacle  242 ′ is essentially similar to the receptacle  242  with the difference being in the size (it is smaller) and in the amount and/or type of ingredients contained therein. 
         [0205]    However, as opposed to the previously described pod  240 , the receptacle  242 ′ has a top foil closure  248 ′ and an auxiliary attachment port  247 ′ configured for attachment with a corresponding port  255  of the receptacle  252 . 
         [0206]    The receptacle  252  is an open receptacle and is configured for containing therein any desired liquid medium by choice of the user, which can be mixed with the ingredients of the receptacle  242 ′ (e.g. juices, water etc.). The receptacle  252  is also formed with a piercing member  259  configured for puncturing the foil closure  248 ′ of the receptacle  242 ′ when the receptacles  242 ′,  252  are properly attached to one another. 
         [0207]    In assembly, the receptacle  252  can be an open end receptacle which can be filled with the desired liquid of choice and then the receptacle  242 ′ can be mounted on the receptacle  252 . 
         [0208]    When attached, the receptacles  242 ′,  252  form together a pod assembly which is very similar in shape and size to the original pod  240  and may thus function in the same way within the machine  200  and the mixing chamber  220 , while providing the user with a greater variety of options and flavors. 
         [0209]    Attention is now drawn to  FIGS. 21A to 21E  in which another example of the machine is shown, generally being designated as  200 ″. As in the previous example, the machine  200 ″ includes a housing  210 ″ accommodating therein a mixing chamber  220 ″ configured for receiving therein a capsule  240 ″ (see  FIG. 22 ) containing at least some ingredients for the preparation of the chilled edible product, a cooling chamber  230 ″ for cooling the edible product/ingredients and a compressor  214 ″. 
         [0210]    However, as opposed to the previously described example, the machine  200 ″ is configured for receiving therein a capsule  240 ″ containing mostly ‘dry’ ingredients (solids, powders etc.) and the mixing chamber  220 ″ is provided with a cover  217 ″ configured for sealing the chamber  220 ″ and a fluid inlet  215 ″ leading thereto through the cover  217 ″. 
         [0211]    With particular attention being drawn to  FIG. 21B , the capsule  240 ″ is smaller than the mixing chamber and does not fill the entire cavity thereof (like the previously described pods  240 ,  240 ′). Instead, fluid is configured for being passed through the cover  217 ″ and into the capsule, so that a mix of the external fluid and ingredients from the capsule  240 ″ are provided into the mixing chamber  220 ″ where they are then mixed. 
         [0212]    In order to provide better diffusion and mixing of the external fluid with the ingredients within the pod, the cover  217 ″ is provided with multiple fluid outlets leading into the capsule  240 ″. The outlets are also designed to puncture a top foil closure of the capsule  240 ″ once placed within the mixing chamber  220 ″ and the cover  217 ″ is properly closed. 
         [0213]    Once the mix of external fluid and ingredients are provided into the mixing chamber  220 ″, mixing takes place there and from then on the manufacture process is very similar to the previously described process of producing the cooled edible product. However, it is appreciated that during mixing, some of the ingredients may remain within the capsule and be mixed there as well, though, not as efficiently as within the mixing chamber. 
         [0214]    Attention is now drawn to  FIG. 22 , in which a capsule  240 ″ is shown comprising a housing  242 ″, a top foil closure  244 ″, a bottom closure  243 ″ (seen in  FIG. 21B ) and a data label  249 ″. The capsule  240 ″ is considerably smaller than the pods  240 ,  240 ′ previously descried and is similar, in general, to coffee capsules. The capsule  240 ″ is configured for being placed within the mixing chamber  220 ″ so that the bottom foil closure  243 ″ thereof is punctured by the piercing element  228  while the top foil cover thereof  244 ″ is configured for being punctured by the outlets formed in the cover  217 ″ when it is properly closed. Turning now to  FIG. 17 , a domestic water supply piping P is shown comprising a faucet F and a hot and cold regulation handles H and C respectively. According to the disclosed subject matter there is provided a water temperature regulation module  300  being in fluid communication with the piping P. 
         [0215]    The module  300  comprises an inlet for receiving fluid from the main piping P, an heating/cooling unit (not shown) and a plurality of ports  310  configured for outputting the received fluid at a desired temperature. 
         [0216]    The module  300  is configured for allowing a plurality of different kitchen appliances (e.g. coffee machine, cooler, the systems  1 ,  101  of the present application) to connect to the ports  310  and receiving from the module the fluid at a desired temperature. 
         [0217]    At present, each of these kitchen appliances is provided with its own heating/cooling module and/or heating body etc. Employing the use of the temperature regulating module  300  allows eliminating the need for a corresponding module in each of the kitchen appliances. This may allow reducing the size and shape of each of these appliances. 
         [0218]    The module  300  can also be provided with a controller (not shown) configured for regulating the temperature of the incoming fluid and controlling provision of the heated/cooled fluid to the relevant port. 
         [0219]    It should be understood that the controller can also be configured for being in communication with each of the connected kitchen appliances, so that the user is not required to operate the module  300 , but rather only the desired appliance. 
         [0220]    Those skilled in the art to which this invention pertains will readily appreciate that numerous changes, variations, and modification can be made without departing from the scope of the invention, mutatis mutandis.
