Title: SYSTEM AND METHOD FOR BREEDING FLIES, PARTICULARLY BLACK SOLDIER FLIES (BSFs)

Description:
TECHNICAL FIELD 
     The present invention relates generally to an industrial method for breeding flies, more particularly to a system and method for breeding flies, specifically Black Soldier Flies (BSFs) that can be used for bioconversion of organic waste into value added products such as fertilizers and animal feed. 
     BACKGROUND 
     Large amounts of organic waste are generated annually from agricultural plantations, animal farms, mills, food processing plants and industrial plants. The amount of organic waste generated has been increasing each year as the agro-food industries expand. These generated organic waste are a major cause of environmental pollution and are of less value to the human and animals. 
     Consequently, the safe disposal and proper utilization of these wastes has been a major concern in recent years. Different methods are available for safe disposal of these organic waste and for conversion of these waste into animal feed and fertilizers. The most acceptable methods for bioconversion of the organic waste into value added products often utilize microorganisms or insects such as different species of larvae of earthworms, house flies, or black soldier flies (BSFs) to efficiently treat the organic waste and produce high quality fertilizers and animal feed. 
     As the demand for such insects, particularly BSF larvae is increasing day by day, it is essential to mass produce or breed these insects/flies at an industrial level to meet ever increasing demand for such insects. 
     There are a number of characteristics of BSFs that have been considered advantageous in bioconversion processes due to which demand for BSFs is increasing. Particularly, BSFs larvae and pre-pupae are high in protein and fatty acid content and exhibit some natural behaviors that is very helpful and yield better results when these BSFs are utilized in the bioconversion process. In an experiment conducted, where 5000 BSFLs were placed into a container with 10 kg of organic wastes. The BSFLs managed to decompose more than 80% of the organic waste within a period of 5 days, which resulted in a reduced volume of the organic waste by 42% and weight by 70%. In comparison to the efficiency of house fly larvae and earthworm larvae widely used in the conventional treatment methods, the BSFLs are found to be more efficient in achieving the desired high value products such as fertilizers and animal feed. In contrast to the earthworm larvae and house fly larvae, the BSFLs spend much longer time decomposing the organic waste. Thus, culturing or reproducing these BSF larvae has become a necessity. 
     The BSF goes through full metamorphosis during its lifespan. The lifespan can be divided into egg, larval, pupae and adult life cycle stages. The larvae will hatch from the egg in about 4 days, and then the larvae will take about 2 weeks before they are ready to pupate (become adults). When they are ready to pupate they will try to find a dry sheltered area to bury themselves in before taking about 2 weeks to emerge as adult BSFs. Adult BSFs live for 5-8 days, this is all assuming that perfect conditions are present for breeding. The length of a Black Soldier Flies (BSF) life before it becomes an adult depends on several factors including weather conditions and how much food is available. BSFs in their pre-pupae larval stage are super-efficient in converting organic waste to nutrients (source: BSF Farming: blacksoldierflyfarming.com). In an appropriate weather conditions, the lifespan of BFSs are estimated to be approx. 37-41 days, thereby making them one of very suitable resource for bioconversion process. 
     A number of prior art discloses various methods and systems for production or breeding of BSFs. For example, U.S. Patent Application number 20110174222 describes about a specific breeding farm comprising a breeding net, induction medium, and a breeding induction apparatus having a plurality of breeding grooves, all of that facilitates breeding of Black Soldier Flies (BSF). 
     The U.S. Pat. No. 8,733,284 describes about an apparatus and method for breeding flying insects, particularly black soldier flies. The apparatus includes a cage and a covered bin. The bin contains a substrate (such as a high permeability/low water retention substrate such as perlite or vermiculite) where insect pupae develop into flies and then go to the cage for mating. The cage and the bin are provided with suitable water supply, air supply, and lighting means to facilitate the breeding process. 
     The Chinese Patent 103598148 describes a black soldier fly cultivation system and method. The system includes a pupation device and an adult black soldier fly cultivation chamber. The pupation device is used for incubating black soldier fly prepupa into black soldier fly pupa, and pupation media with water is disposed inside the pupation device to facilitate this incubation. The adult black soldier fly cultivation chamber is used for cultivating the black soldier fly pupa into adult black soldier fly. 
     The U.S. patent Ser. No. 10/159,229 describes apparatus and method for culturing Dipteran insects, particularly BSF. The apparatus in particular include a mating chamber to hold adult insects, and adaptations for various inputs such as: empty egg laying substrate, prepupae, bedding, carbohydrate, and various outputs such as egg laying substrate containing eggs, exuvia and bedding, and/or dead adults. The apparatus may also include adaptations to optimize the use of space including the use of controlled environmental conditions within a confined space. 
     Many other inventors also envisioned several methods and systems for mass-rearing of black soldier fly larvae (BSFL) or flies of like nature, some of those systems and methods are described in the US20180360008, U.S. Pat. No. 8,322,302, KR100654253, U.S. Pat. No. 9,462,795, KR101044636, and U.S. Pat. No. 5,351,643. 
     Despite various improvements and proposals, there exists a need for an improved and more reliable solution, particularly a system and method for massive culturing or breeding of the Black Soldier Flies (BSFs).

Thus, these terms are not necessarily intended to indicate temporal or other prioritization of such elements. 
     Described herein are systems and methods for breeding insects/flies particularly Black Soldier Flies (BSFs) that can be used for bioconversion of organic waste into value added products such as fertilizers and animal feed. The system and method disclosed herein allow for the breeding and harvesting of the BSF, also known as Hermetia illucens, and their larvae. However, the disclosed system and method are not limited to this insect species and, according to some embodiments, may be applied to other insect species as well. 
     The described system and method facilitates the full lifecycle of the BSFs and their larvae, and attempts to automate the lifecycle on a commercial scale. The system disclosed herein for breeding is capable of being scaled up for larger production of the BSFs. 
     The various features and embodiments of the present system and method for breeding flies, particularly the BSFs are better explained in conjunction with  FIGS. 1-11 . 
     Referring to accompanying figures, particularly the  FIGS. 1-4 , the system  100  primarily includes a treatment chamber  102 , a dark chamber  104 , a fly chamber  106 , and a hatching chamber  108  all operationally interconnected to each other to facilitate breeding of BSFs. The treatment chamber  102  as best shown in the  FIG. 5 , is preferably made circular or semi-circular in shape. The treatment chamber  102  may be made of any suitable metallic or non-metallic material. The treatment chamber  102  is made hollow inside and include two open ends  150 , and  151 . The treatment chamber  102  further includes an integral pathway  102   a  that leads to a first circumferential opening  102   b  associated therewith. The pathway  102   a  is inclined at a predetermined angle. In an example, the predetermined angle is about 40 degrees. The circumferential opening  102   b  associated with the treatment chamber  102  is of a predetermined width. In an example, the predetermined width is about 1″. 
     The treatment chamber  102  is configured to receive pre-pupae larvae or early stage pre-pupae larvae, and receive feed material for the pre-pupae larvae to feed on, and undergo pupation. The feed material preferably include but not limited to organic food material such as rotten vegetables. The feed material and the early stage pre-pupae larvae may be disposed into the treatment chamber  102  using several known techniques, however in the light of present invention, the feed material and the early stage pre-pupae larvae may be disposed or deposited inside the treatment chamber  102  using pumping systems known in the art. 
     Further to facilitate proper weather conditions within the treatment chamber  102 , the treatment chamber  102  may include provisions such as one or more passageways, for example passageways  111  to pump in/channel in air inside the treatment chamber  102 , and passageways  112  to pump out/channel out air from the treatment chamber  102 . This is necessary in order to maintain adequate level of moisture inside the treatment chamber  102  so that the early stage pre-pupae larvae can actively consume the feed material. The treatment chamber  102  further facilitate the pre-pupae larvae to develop into pupae in the provided suitable weather conditions therein. The passageways  111  and  112  may be provided with mesh filters to prevent escaping out of any pre-pupae larvae through those passageways. 
     The system  100  further includes the dark chamber  104  in communication with the treatment chamber  102 . The dark chamber  104  as best shown in the  FIG. 6 , is preferably made circular or semi-circular in shape. The dark chamber  104  may be made of any suitable metallic or non-metallic material. The dark chamber  104  is made hollow inside and include two open ends  160 , and  161 . The dark chamber  104  includes a second circumferential opening  104   a , and a third circumferential opening  104   b  associated therewith. The circumferential opening  104   a  associated with the dark chamber  104  is of a predetermined width, preferably equal (but not necessary) in width to the first circumferential opening  102   b  of the treatment tower  102 . The width of the circumferential opening  104   a  is preferably made equivalent to the width of the circumferential opening  102   b  so that during the engagement of the treatment chamber  102  and the dark chamber  104 , those two openings  102   b ,  104   a  can coincide with each other to form a common passageway leading to the dark chamber  104 . The width of the circumferential opening  104   a  should be made suitable such that it forms a passageway and can allow pupated larvae from the treatment chamber  102  to crawl and get into the dark chamber  104 . Specifically, allow the pupated larvae to crawl over the pathway  102   a  via the first circumferential opening  102   b , and the second circumferential opening  104   a  to reach the dark chamber  104 . It is the dark chamber  104  that permit the pupated larvae to transition into adult flies. The dark chamber  104  is configured to be very dark (without any light) and dry that helps in the transition of the pupated larvae to the adult flies. The third circumferential opening  104   b  of the dark chamber  104  is of a predetermined width. The width of the circumferential opening  104   b  may or may not be equivalent to the width of the circumferential opening  104   a . In an example, the width of the circumferential opening  104   b  is 1.5″. 
     The circumferential opening  104   b  is selectively openable and closable by a gate  140  that&#39;s controllable by an actuator  140   b . The actuator  140  may be an electrical actuator or a hydraulic actuator. As seen in the  FIG. 10 , the gate  140  includes a ring member  140   a , semi-circular in shape complementing to the shape of the dark ring  104 . The width of the ring member  140   a  is made equal to the width of the circumferential opening  104   b . The actuator  140   b  is connected to the ring member  140   a  using a shaft  140   c . According to the embodiment, and as best shown in the  FIG. 4 , the actuator  140   b  is housed or disposed within a central shaft  110 . Further, the actuator  104   b  nay be provided with one or more bearings to ensure the gate  140 , particularly the ring member  140   a  doesn&#39;t rotate when the central shaft  110  is made to rotate for rotating the rotating member  110   a . The central shaft  110  is partially or fully opened on top to facilitate the operation of the actuator  140   b  disposed therein. The central shaft  110  includes a rotating member  110   a  mounted thereon and configured in a way to engage with the treatment chamber  102  and the dark chamber  104 . The engagement of the rotating member  110   a  with the treatment chamber  102  and the dark chamber  104  completes the semi-circular shapes of the treatment chamber  102  and the dark chamber  104 . The central shaft  110  when rotated using a motor (not shown) facilitate internal cleaning of the treatment chamber  102  and the dark chamber  104  to rinse of any remaining waste or died flies or larvae present therein. In operation, the two ends  150 , 151  of the treatment chamber  102 , and the two ends  160 ,  161  of the dark chamber  104  are open and thus facilitate the solid rotating member  110  to rotate therein when the central shaft  110  is rotated. 
     Besides being dark and dry, the dark ring  104  according to the embodiments may also require an appropriate atmospheric condition inside for the pupated larvae to convert to the flies. The atmospheric condition inside the dark chamber  104  may be maintained using air supply provisions or one or more passageways, such as  113  for channeling in/pumping in air inside the dark chamber or pumping out/channeling out the air out of the dark chamber  104 . The passageway  113  may be provided with mesh one or more filters to prevent escaping out of any adult flies through those passageway. 
     In operation, when the pupated larvae is converted to the adult flies, the actuator  140   b  may be activated to move the piston in upward direction and open the gate  110  (that&#39;s initially in closed state). This would allow the adult flies to fly out of the dark chamber  104  and be collected into a fly chamber  106  in communication with the dark chamber  104 . According to the embodiment, an additional light source (not shown) may be positioned at a suitable location over the fly chamber  106  may be selectively activated to act on the adult flies and urge them to leave the dark chamber  104  and fly into the fly chamber  106  for mating and spending rest of their lifecycle. In an example, the light source is a LED light source. In another example, the light source may be halogen lamps readily available in the market. Although not explicitly shown, the light source may preferably be configured on top of the fly chamber  106 . As shown in the  FIG. 7 , the fly chamber  104  may have an opening or spacing  106   c  at bottom to allow the flies from the dark chamber  104  to fly into the fly chamber  106 . When in the fly chamber  106 , the flies usually don&#39;t require any feed material and only water supply is sufficient to keep them lively. Thus, one or more passageways may be used, such as passageways  114 ,  115  for supplying water, and also for pumping in air and out of the fly chamber  106 . The passageways  114  and  115  may be provided with one or more mesh filters to prevent escaping out of any flies through those passageways. 
     According to various embodiment, the fly chamber  106  may be provided with a vibration source (not shown) positioned at a suitable location over the fly chamber  106  that can be selectively activated to act on the adult flies to urge them to participate in matting for higher yield of the eggs. In an example, the vibration source is an audio speaker that can play music. Further, according to the embodiment, the fly chamber  106  may further be provided with a plant like motivation element (not shown) positioned at a suitable location inside the fly chamber  106  (on top preferably) to urge the flies to sit thereon and mate. 
     The fly chamber  106  is cylindrically shaped and made of wire mesh material  106   a  sufficient enough to prevent the flies from escaping away. Further, the fly chamber may  106  be lined with a transparent screen  106   b  from outside. The wire mesh material  106   a  may be metallic or non-metallic. The transparent screen  106   b  adapted for covering the wire mesh material  106   a  may be made of thin plastic material. The transparency in the screen  106   b  may assist in visualizing internal environment conditions within the fly chamber  106 . Further, the transparent screen  106   b  may also help with letting the adequate sunlight enter inside the fly chamber  106 , which is essential for this stage of their lifecycle. The fly chamber  106  is configured to permit the adult flies to mate and oviposit eggs utilizing an oviposition arrangement. 
     In the context of the present invention, the oviposition arrangement refers to arrangements or components that in general help the flies in laying eggs. According to the embodiment, the oviposition arrangement includes an attractant holder  108   b  configured onto a hatching chamber  108  or one that forms a part of the hatching chamber  108  as shown in the  FIG. 8 . The attractant holder  108   b  according to an embodiment holds attractant (not shown). The attractant may include but not limited to the feed material and antibiotics added therein to preserve the feed material for a longer duration. At this stage, the flies have strong senses, thus the flies are attracted towards this attractant for laying eggs (oviposition), and this also helps the flies to fly towards the region of attractant and sit and lay eggs on a plurality of bio-balls configured over top of the attractant holder  108   b.    
     The bio-balls  109   a  forming a part of the oviposition arrangement, such as bio-balls  109   a  (as shown in the  FIG. 11 ) is configured to receive the eggs deposited by the adult flies. The bio-balls  109   a  may be made of any suitable materials, such as but not limited to wood. The bio-balls  109   a  are configured in but not limited to circular shape with apertures distributed over their surface so that the adult flies can lay eggs into the balls  109   a . The bio-balls  109   a  are preferably stuffed with sponge or like soft material for preventing any accidental damage to the eggs deposited therein. The balls  109   a  are mounted over a framework  109   b . The framework  109   b  is coupled to an L-member  109   c ,  109   d  (configured as two pieces attached to each other or as a one piece item). The L-member  109   c ,  109   d  may be selectively operated to rotate the framework  109   b , which in turns rotate the bio-balls  109   a  mounted thereon. In operation, once the bio-balls or balls  109   a  has eggs deposited therein, then the framework  109   b  may be rotated using a motor (not shown) preferably a step motor in 180 degrees to move the bio-balls  109   a  from the fly chamber  106  to the hatching chamber  108 . This rotation is along horizontal plane along the direction P. The hatching chamber  108  is further provided with a brush (not shown) configured to remove the flies present over the bio-balls  109   a  when the bio-balls  109   a  are rotated from the fly chamber  106  to the hatching chamber  108 . In the preferred embodiment, the L-member  109   c ,  109   d  and the framework  109   b  are configured to rotate the bio-balls  109   a  along a horizontal plane, it should be understood that the framework  109   b  may be suitably configured to rotate the bio-balls  109   a  along a vertical plane along the direction ‘R’ as shown in the  FIG. 13 . 
     The hatching chamber  108  is configured to facilitate hatching of the eggs contained inside the bio-balls  109   a  to produce early stage larvae, which may be collected and maintained in a hollow hatch box region  108   a  of the hatching chamber  108 . Like other chambers, namely the treatment chamber  102 , the dark chamber  104 , the fly chamber  106 , it is also essential to maintain appropriate atmospheric conditions suitable for the growth of the early stage larvae. According to the embodiments, the hatching chamber  108  may be supplied by a source of diet food that&#39;s required for the growth of the early stage larvae and may be provided with air circulation provisions (one or more passageway) such as passageway  116  to maintain the perfect atmospheric condition for the growth of the larvae. The passageway  116  may be provided with one or more mesh filter to prevent escaping out of any flies through the passageway. The larvae after hatching will feed in the hatch box region  108   a  for a couple of days or so until water start to spray on the surface of the box  108   a . Once the larvae has spent desired number of days and evolved into appropriate larvae preferably 5 days old larvae (DoL), an ejector pump  117  at the bottom of the hatching chamber  108  may be opened to transfer the 5 DoL to a shaker/separator means where the 5 DoL will be separated and suitably stored for use in conversion of the organic waste to the value added product such as quality fertilizers or animal feed. According to the embodiment, the hatching chamber  108  is preferably half-moon shaped. According to some other embodiment, the hatching chamber  108  may be made square in shape. Although, the embodiment of present invention is describes harvesting of larvae out of the hatching chamber  108  when they are 5 days old, it should be understood that within the scope of the scope of present invention, even larvae of 3 days old, 4 days old, 6 days old, 7 days old etc. can also be harvested, it is just that, 5 days old larvae (SDoL) is capable of yielding better results to act on the organic waste to convert them into value added products. 
     Referring to the  FIGS. 12-13 , an alternative embodiment of the system  100  is shown. Particularly, the elements/components shown in the  FIG. 12  are identical to the components shown and described with respect to the  FIGS. 1-11 , except the hatching chamber  108 .
