As another example of the present invention, in the egg/larva inoculation means, a plurality of eggs of flies are inoculated in a heap at equal intervals on the surface of the prey contained in the prey storage container, and in the prey decomposition means, from the eggs. Immediately after hatching, the first-instar larvae are fed with a prey to grow into larvae exhibiting phagocytosis.

As another example of the present invention, the okara treatment system utilizes the active peristaltic discrete behavior of the 3rd instar larvae which has undergone the pupal metamorphosis stage after the second molting from the 1st instar larva immediately after hatching from an egg. It includes a separation means for separating the instar larvae and the degradation products of the prey.

As another example of the present invention, the okara treatment system collects a part of the 3rd instar larvae from the 3rd instar larvae after molting from the 1st instar larvae hatched from an egg, and collects the 3rd instar larvae. It includes a means for rearing flies by rearing and transforming pupae into adults and collecting flies eggs from the adults.

As another example of the present invention, the okara treatment system collects the remaining 3rd instar larva from the 3rd instar larvae of the fly, excluding the 3rd instar larva used for alternation of generations, and uses the remaining 3rd instar larvae for food. Insect food raw material making means for making insect food raw material is included.

As another example of the present invention, the Okara treatment system collects the remaining 3rd instar larva from the 3rd instar larvae of the fly, excluding the 3rd instar larva used for alternation of generations, and uses the remaining 3rd instar larvae for feeding animals. It includes a feed ingredient preparation means for producing the feed ingredient.

As another example of the present invention, the prey preparation means mixes a predetermined amount of okara with a predetermined amount of disaccharide to prepare a prey.

As another example of the present invention, the disaccharide is at least one of sucrose, lactulose, lactose, maltose, trehalose, and cellobiose.

As another example of the present invention, the agricultural waste is at least rice husk of rice husks and vegetable scraps, and the weight ratio of the agricultural waste to the total weight of prey is in the range of 5 to 10% by weight. It is in.

According to the okara treatment system according to the present invention, a predetermined amount of agricultural waste is mixed with a predetermined amount of okara, and a predetermined amount of agricultural waste is dispersed inside the predetermined amount of okara, thus larvae of a fly. Makes a predetermined amount of prey with a peristaltic space, and inoculates the prey contained in the prey storage container with a plurality of fly eggs, or inoculates the prey stored in the prey storage container with fly larvae. Then, while worming multiple larvae hatched from the eggs or larvae inoculated into the prey, the larvae are allowed to prey on the larvae by peristalting the voids of the prey contained in the prey storage container, and the larvae are growing. Since the prey is enzymatically decomposed in the body of the larva, the food habit of the fly larva that prefers to eat the prey eaten first is utilized to increase the appetite (feeding) of the larva and to remove a large amount of prey (prey). It can be processed efficiently in a short period of time. The Okara treatment system forms voids in the prey by agricultural waste, and multiple larvae hatched from eggs or larvae inoculated into the prey peristalticize the voids, so the larvae can easily peristalize inside the prey. In addition, the larvae of larvae of flies can be activated to enhance the appetite of the larvae, and a large amount of okara (prey) can be fed to the larvae in a short period of time. The okara treatment system can process a large amount of okara (prey) safely and inexpensively by utilizing the food habits of the fly larvae, because the okara (prey) is enzymatically decomposed in the body of the fly larva. ..

The Okara treatment system includes a sterilization means for sterilizing a predetermined amount of okara and a predetermined amount of agricultural waste and sterilizing the prey container, and sterilizing the okara, agricultural waste, and prey container. By doing so, it is possible to prevent the propagation of various bacteria in okara, agricultural waste, and prey storage containers, and to develop larvae that do not contain pathogens and do not generate odors in the processing of okara (prey). The larvae can be safely treated by utilizing the food habits of clean larvae. The okara treatment system can prevent the occurrence of disease in larvae and improve the survival rate of larvae.

The Okara treatment system, in which a plurality of prey storage containers containing prey are stacked vertically to form a breeding floor, and the breeding floor is stored in a treatment space of a predetermined volume, uses multiple prey storage containers and breeds them. By using the floor, you can efficiently treat a large amount of tofu (prey) at a time while keeping a large number of fly larvae at one time Can be processed.

After inoculating the prey with fly eggs, the temperature of the treatment space is kept in the range of 20 to 50° C. (preferably 20 to 40° C.) between the eggs and the hatching of the larvae, and the humidity of the treatment space is kept. 60 to 100% (preferably 60 to 90%), and the temperature of the treatment space is in the range of 20 to 50°C (preferably 20 to 40°C) after hatching of larvae from eggs or after inoculation of larvae. In the Okara treatment system, the temperature of the treatment space is maintained at 30 to 50° C. (preferably 20 to 40° C.) between the egg and the larvae hatching. By maintaining the humidity of the treatment space at 60 to 100% (preferably 60 to 90%) while keeping the temperature in the range of 60° C.), it is possible to improve the hatching rate of larvae that hatch from eggs, and The survival rate of larvae can be improved. The okara treatment system keeps the temperature of the treatment space in the range of 20 to 50° C. (preferably 20 to 40° C.) after hatching the larvae from the eggs or inoculating the larvae, and keeps the humidity of the treatment space at 65 to 65° C. By keeping it in the range of 80%, the survival rate of fly larvae can be improved, the growth of larvae can be promoted, and a large amount of larvae can be utilized by utilizing their vigorous appetite. Can be efficiently treated in a short period of time. The okara treatment system can optimize the growth environment for eggs and larvae, prevent death of eggs and larvae due to environmental degradation, and improve hatchability and survival rate.

In the prey preparation means, the okara treatment system in which the water content of the okara to be fed to the fly larvae is adjusted within the range of 60 to 80% causes the okara to harden when the water content of the okara is insufficient and ), the peristalsis of larvae is restricted, and the water content of okara is higher than necessary, the density of okara in the prey decreases, the growth environment for larvae deteriorates, and the appetite (feeding) of larvae decreases. However, since the water content of Okara is in the above range, the larval peristalsis in Okara (prey) is not hindered, and the density of Okara in prey becomes optimum. , A large amount of okara (prey) can be efficiently treated in a short period of time by vigorous peristalsis of fly larvae and active appetite (larvae) of larvae. The Okara treatment system can optimize the growth environment for eggs and larvae by setting the water content of Okara to the above range, prevent the death of eggs and larvae due to environmental deterioration and improve the hatching rate and survival rate. Can be made.

In the egg/larva inoculation means, a plurality of eggs of flies are inoculated on the surface of the prey housed in the prey storage container at equal intervals and inoculated on a heap, and in the prey decomposition means, the first-instar larvae immediately after hatching from the eggs are inoculated. The okara treatment system that grows into larvae that show feeding habits by feeding prey is a fly existing in nature that lays a plurality of eggs in a medium in a heaped state, thereby increasing the hatching rate from eggs, Since the survival rate of the species is improved, it is possible to similarly inoculate a plurality of eggs on the surface of the prey in a heap and improve the hatching rate of larvae that hatch from the inoculated eggs. The survival rate can be improved. The okara treatment system utilizes the characteristics of the fly larvae that prefer to eat the prey they eat first, and feeds the first-instar larvae immediately after hatching from the eggs to grow into larvae that show ocular feeding habits. It is possible to efficiently treat a large amount of tofu (prey) in a short period of time while improving the appetite (feeding) of larvae and utilizing the active appetite (feeding) of larvae.

Okara treatment system that separates the 3rd instar larva from the degradation product of prey by using the active peristaltic discrete behavior of the 3rd instar larva which has undergone pupal metamorphosis after the second molting from the 1st instar larva immediately after hatching from the egg Uses the vigorous peristaltic dispersal behavior of the 3rd instar larva that has undergone pupal metamorphosis to separate the 3rd instar larva from the okara (prey) degradation product, and thus the peristalsis is separated from the degradation product when the larva undergoes pupal metamorphosis. By utilizing the habit, the work of separating the fly larvae and the decomposed product from humans can be omitted, and the third-instar larvae and the decomposed product of Okara (prey) are separated without time and effort. can do. The Okara treatment system prevents the third-instar larva of the fly from remaining in the decomposed product of Okara (prey), and can prevent the generation of adult flies from the decomposed product of Okara (prey).

From the first-instar larvae that hatched from the eggs, a part of the third-instar larvae was collected from the group of the third-instar larvae after molting, and the collected third-instar larvae were bred and transformed from pupae to adults. The Okara treatment system, which changes the generation of flies by collecting eggs, uses the larvae that hatched from the eggs to cause the adults, who have grown a part of the third-instar larvae group, to lay the next-generation eggs. Since the tomato (prey) is processed, it is not necessary to newly procure the fly eggs from the outside, the fly can be used in a semi-permanent cycle, and the tofu (prey) can be processed at a low price.

The Okara treatment system that collects the remaining 3rd instar larva excluding the 3rd instar larvae used for generational change from the 3rd instar larvae of the fly and produces the insect food material used for food from the remaining 3rd instar larvae By feeding clean okara, the fly larvae can be converted into an insect food material used for food, and okara can be effectively used without waste. Okara processing system can produce insect food raw materials by using the okara that has been discarded so far, so it is possible to obtain the insect food raw materials used for insect food from the discarded okara, which will be generated in the future. You can make up for food shortages by doing fly larvae and okara. It should be noted that the insect food material contains high protein and abundant chitosan, and by eating an insect food made from the insect food material, the immunity and natural healing power can be enhanced.

The Okara treatment system that collects the remaining 3rd instar larva excluding the 3rd instar larva used for generational alternation from the 3rd instar larvae of the fly and makes the feed material for farm animals from the remaining 3rd instar larvae By feeding okara, the fly larvae can be converted into a feed material for domestic animals, and the okara can be effectively used without waste. The okara treatment system can produce feed ingredients for domestic animals using the okara that has been discarded up to now, so it is possible to obtain the feed ingredients to feed the animals from the discarded okara, The shortage of feed material for domestic animals that occurs in the future can be compensated by fly larvae and okara. It should be noted that the feed raw material contains high protein and abundant chitosan, so that it is possible to enhance the immunity and natural healing power of the animal fed with the feed raw material.

In the prey preparation means, a predetermined amount of dill is mixed with a predetermined amount of disaccharide to make a prey, and an okara treatment system mixes the okara with the disaccharide to produce an appropriate sugar content for the okara (prey). Larvae that eat okara (prey) contain sugars, and fly larvae can be converted to edible insect food materials that contain sugars, and fly larvae contain sugars. It can be converted into feed material for domestic animals. Since the insect food raw material contains sugar and abundant chitosan, it is possible to make an insect food with high protein and nutritive value. Since the feed raw material contains sugar and abundant chitosan, high protein and nutritive value can be obtained. It can make high feed ingredients.

The okara treatment system in which the disaccharide is at least one of sucrose, lactulose, lactose, maltose, trehalose, and cellobiose, the okara is mixed with at least one of sucrose, lactulose, lactose, maltose, trehalose, and cellobiose. By doing so, an appropriate amount of sugar can be added to the okara (prey), the larvae that ate the okara (prey) contain sugar, and the fly larvae are used as an edible insect food material containing sugar. The larvae of the fly can be converted into a feed material for a feed animal containing sugar. Since the insect food raw material contains sugar and abundant chitosan, it is possible to make an insect food with high protein and nutritive value. Since the feed raw material contains sugar and abundant chitosan, high protein and nutritive value can be obtained. It can make high feed ingredients.

An okara treatment system in which the agricultural waste is at least rice husks of rice husks and vegetable scraps, and the weight ratio of the agricultural wastes to the total weight of prey is in the range of 5 to 10% by weight. By adding rice husks and vegetable scraps in the above weight ratio, an appropriate gap can be created in the prey, so that the larvae can easily peristalize inside the prey, and activate the peristaltic habit of the fly larvae. In addition, the vegetable scraps become appetite (appetite) enhancers that enhance the appetite (appetite) of the larvae, which can enhance the appetite of the larvae, and the active peristalsis of the fly larvae and the robust appetite of the larvae (appetite). With, a large amount of okara (prey) can be efficiently processed in a short period of time.

At the lower part of the side plates 32, a positioning recess 45 is formed which is recessed upward in the vertical direction and into which the positioning projection 44 is removably inserted. In the prey storage tray 20, a bottom plate 31 and side plates 32 define a prey storage recess 46 having a predetermined volume. In the prey storage recess 46 of the prey storage tray 20, a reference line 47 that serves as a guide when the prey 19 is spread is displayed.

In the prey accommodation recess 46, three partition plates 48 are installed that are spaced apart at equal intervals in the lateral direction and extend straight in the front-rear direction. The one partition plate 48 extends from the front end portion 37 of the front portion 34 of the bottom plate 31 toward the central portion 33 and reaches the center of the central portion 33. The other partition plate 48 extends from the front end portion 41 of the rear portion 35 of the bottom plate 31 toward the central portion 33 and reaches the center of the central portion 33. The number of partition plates 48 is not limited to the three shown in the figure, and four or more partition plates 48 may be installed in the prey accommodation recess 46.

The prey storage trays 20 are installed and fixed inside the fixed frame 28, and six of them are stacked in a state that they are vertically spaced at equal intervals. The number of prey storage trays 20 on the breeding floor 15 is not particularly limited, and seven or more storage trays 20 may be stacked. In the prey storage tray 20, the positioning projections 44 of the storage tray 20 located above are fitted into the positioning recesses 45 of the storage tray 20 located below, and the storage trays 20 are fixed in a state of being vertically aligned. There is.

FIG. 7 is a side view of the breeding floor 15 in which a plurality of prey storing trays 20 are vertically stacked, and FIG. 8 is a top view of the prey storing tray 20 in the breeding floor 15 of FIG. 7. FIG. 9 is a side view of the breeding floor 15 in a state in which the 1st instar larva 50a or the 2nd instar larva 50b is eating the prey 19, and FIG. 10 is a top view of the prey storage tray 20 in the breeding floor 15 of FIG. is there. FIG. 11 is a side view of the breeding floor 15 showing a state in which the third-instar larva 50c falls into the collection container 27, and FIG. 12 is a top view of the prey storage tray 20 in the breeding floor 15 of FIG. 7 and 8, the prey 19 is stored in the prey storage tray 20, and the surface of the prey 19 is inoculated with the egg 49. 11 and 12, a part of the prey 19 eaten by the larva 50 is changed to a decomposed product 51 (low-concentration organic decomposed product) (fertilizer base material). The partition plate 48 is not shown in FIGS.

Each means implemented in the organic fertilizer manufacturing system 10A of FIG. 1 will be described below. A certain amount of tofu 17 generated in the tofu manufacturing plant is transferred from the tofu manufacturing plant to the Okara processing plant (Okara processing system 10A) by a predetermined transportation means (transport vehicle, belt conveyor, transport carriage, etc.) (not shown). It is transported to and is temporarily stored (pool) in the temporary storage box of the Okara processing plant. Okara 17 stored in the Okara temporary storage box is processed within the same day when it is picked up from the tofu manufacturing plant, or within 24 hours after being received by the Okara processing plant. Rice husks 18a (agricultural waste 18) and vegetable scraps 18b (agricultural waste 18) mixed in Okara 17 are stored in the Okara processing factory after being collected from farmers, agricultural cooperatives, industrial waste contractors, etc. Be stored.

Okara 17 stored in the Okara temporary storage box is sterilized (heated steam sterilization) (sterilization means (sterilization process)). The rice husk 18a (agricultural waste 18) mixed in the okara 17 is subjected to hot water sterilization, hot air sterilization, and cleaning with hypochlorous acid water before use (sterilization treatment means (sterilization treatment step)), The vegetable waste 18b (agricultural waste 18) mixed in the okara 17 is washed with hypochlorous acid water (sterilization treatment means (sterilization treatment step)). The vegetable waste 18b that has been sterilized is crushed by a crusher and processed into a vegetable waste crushed product 18b. The collection container 27 and the prey storage tray 20 are subjected to hot water disinfection, hot air disinfection, and cleaning with hypochlorous acid water (sterilization processing means (sterilization processing step)). The sterilization means (sterilization step) can be omitted.

The okara treatment system 10A (including the okara treatment system 10B) sterilizes the okara 17, the agricultural waste 18, the prey storage tray 20 (prey storage container), and the collection container 27, so that the okara 17 and the agricultural production Propagation of various bacteria in the waste 18, the prey storage tray 20, and the collection container 27 can be prevented, and no foul odor is generated in the treatment of Okara 17 (prey 19) and no pathogenic bacteria are propagated. By using the food habits of the clean larva 50, Okara 17 (prey 19) can be safely treated. The okara treatment system 10A (including the okara treatment system 10B) can prevent the occurrence of a disease in the larva 50 and improve the survival rate of the larva 50.

The tofu 17, rice husk 18a, and crushed vegetable scraps 18b that have been sterilized are put into the stirrer 11 from a sterilization plant or a crusher by a belt conveyor (not shown) (water may be added in some cases). .. The okara 17 and the rice husk 18a and the crushed vegetable scraps 18b are stirred and mixed in the stirrer 11 to prepare a prey 19 (prey preparation means (prey preparation step)). In the prey preparation means (prey preparation step), the housefly larvae 50 are easily peristaltic by mixing and dispersing a predetermined amount of rice husks 18a and vegetable scraps 18b (agricultural waste) in the predetermined amount of tokara 17. Voids are formed. It should be noted that only the okara 17 and the rice husk 18b excluding the crushed vegetable scraps 18b are charged into the stirrer 11 (water may be added in some cases), and the okara 17 and the rice husk 18a are stirred and mixed in the stirrer 11 to prey 19 May be produced (prey preparation means (prey preparation step)). In addition to okara 17, rice husk 18a and crushed vegetable scraps 18b, sake lees, stepped lees, mirin lees, coffee lees, shochu lees, beer lees, rapeseed lees, pine lees, tea lees, wine lees, starch lees There is a case where at least one of the above is charged into the stirrer 11 (water may be charged in some cases), and in the stirrer 11 they are stirred and mixed to form the prey 19 (prey preparation means (prey preparation step)).

Agricultural waste 18 (rice husk 18a, crushed vegetable waste 18b, lees) not only enhances the appetite (food habit) of the housefly larva 50, but also functions as a water regulator for Okara 17 (prey 19). When the okara 17 contains a large amount of water, the input amount (mixing amount) of the rice husk 18a is increased. When the water content of the okara 17 is insufficient, the amount (mixed amount) of the crushed vegetable scraps 18b and the lees is increased. If water is still insufficient, add water to Okara 17. In the Okara treatment system 10A (including the Okara treatment system 10B), by mixing agricultural waste 18 (rice husk 18a, crushed vegetable scraps 18b, lees) and water into Okara 17, prey 19 (Okara) The water content (17) is adjusted, and the water content (viscosity) of the prey 19 is adjusted.

The weight ratio of the agricultural waste 18 to the total weight of the prey 19 is in the range of 5% by weight to 10% by weight. If the weight ratio of the agricultural waste 18 to the total weight of the prey 19 is less than 5% by weight, it is not possible to form a proper gap in the prey 19, and it is impossible to activate the peristaltic habit of the housefly larva 50, and the housefly Cannot increase the appetite (feeding) of the larvae 50 of. When the weight ratio of the agricultural waste 18 to the total weight of the prey 19 exceeds 10% by weight, the amount of the okara 17 with respect to the prey 19 decreases, and a large amount of the okara 17 cannot be efficiently treated in a short time.

The Okara treatment system 10A (including the Okara treatment system 10B) is a prey by adding the rice husk 18a, the crushed vegetable scraps 18b, and the lees of the above weight ratio (5 wt% to 10 wt%) to Okara 17. Since a proper gap can be made in the larva 19, the larvae 50 can easily peristalize inside the prey 19, which can activate the peristaltic habit of the housefly larvae 50, and the crushed vegetable scraps 18b and lees Becomes an appetite (appetite) enhancer that enhances the appetite (appetite) of the larvae 50, and can enhance the appetite of the larvae 50, and the active peristalsis of the housefly larvae 50 and the vigorous appetite of the larvae 50 A large amount of tokara 17 (prey 19) can be efficiently treated in a short period of time.

The water content of the okara 17 fed to the housefly larvae 50 is adjusted by the agricultural waste 18 in the range of 60% to 80%. When the water content of Okara 17 is less than 60%, the water content of Okara 17 is insufficient and the viscosity of the prey 19 increases, and the prey 19 (Okara 17) hardens, and the larvae 50 in the Okara 17 (prey 19) The peristalsis is limited, the larva 50 cannot actively move around in the prey 19, and the larva 50 cannot eat the prey 19 (okara 17) smoothly. When the water content of Okara 17 exceeds 80%, the water content of Okara 17 becomes unnecessarily high, the density of Okara 17 in the prey 19 decreases, the growth environment for the larva 50 deteriorates, and the appetite of the larva 50 increases. (Food habit) deteriorates, and a large amount of tokara 17 (prey 19) cannot be efficiently treated.

Okara treatment system 10A (including Okara treatment system 10B) adjusts the viscosity of prey 19 (Okara 17) by setting the water content of Okara 17 (prey 19) to the above range (60% to 80%). Since it can be moderately done, the peristalsis of larva 50 in Okara 17 (prey 19) is not disturbed, the density of Okara 17 in prey 19 is optimized, and the peristaltic habit of housefly larva 50 is activated. The larva 50 can smoothly feed on the prey 19 (okara 17), and a large amount of tora 17 (or eating habit) due to the active peristalsis of the housefly larva 50 and the vigorous appetite of the larva 50 (food habit). Prey 19) can be treated efficiently in a short period of time. The Okara treatment system 10A (including the Okara treatment system 10B) can optimize the growth environment for the egg 49 and the larva 50 by setting the water content of the Okara 17 in the above range, and the egg 49 caused by the environmental deterioration. It is possible to prevent the death of the larvae 50 and larvae and improve the hatching rate and survival rate.

After the prey 19 is prepared by the prey preparation means, the prey 19 is transferred from the stirrer 11 to the quantitative cutting machine 12. In the fixed quantity cutting machine 12, the prey 19 is weighed and the set amount of the prey 19 is discharged from the discharge port. The set amount of prey 19 discharged from the outlet of the fixed amount cutting machine 12 drops to the prey storage tray 20 located below the cutout machine 12, and the prey of the prey storage tray 20 placed on the belt conveyor 13 is fed. It is accommodated in the accommodation recess 46 (prey accommodation means (prey accommodation step)). The prey 19 is flattened so as to fit the reference line 47 of the prey storage tray 20. The loose treatment system 10A (including the okara treatment system 10B) uses a plurality of prey storage trays 20 (prey storage containers) and a plurality of breeding floors 15 to store a large number of houseflies at a time. The larvae 50 can be bred and a large amount of Okara 17 (prey 19) can be treated at one time.

The prey storage tray 20 in which the prey 19 is stored is moved by the belt conveyor 13 from the constant amount cutting machine 12 toward the lifting lifter 14. In the process in which the prey storage tray 20 moves on the belt conveyor 13 from the constant amount cutting machine 12 to the lifting lifter 14, a plurality of housefly eggs 49 of a predetermined amount are inoculated (supplied) on the surface of the prey 19 (egg. Larva inoculation means (egg/larva inoculation process)). In addition, in the process in which the prey storage tray 20 moves on the belt conveyor 13 from the quantitative cutting machine 12 to the lifting lifter 14, the plurality of first instar larvae 50a or the first instar larvae 50a of the housefly immediately after hatching from the egg 49 are grown. The second instar larvae 50b are evenly and uniformly inoculated (supplied) throughout the prey 19 (egg/larva inoculation means (egg/larva inoculation step)).

In the egg/larva inoculation means (egg/larva inoculation step), the eggs 49 are not evenly spread over the entire surface of the prey 19, but a plurality of eggs 49 are on the surface of the prey 19 and the central portion 33 of the bottom plate 31. And the front and rear portions 34, 35 are inoculated on the heaps in a state of being laterally spaced apart (see FIG. 7). Since houseflies present in nature spawn multiple eggs in the medium in a heaped state, thereby increasing the hatchability from eggs and improving the survival rate of seeds, similarly, multiple eggs 49 are also produced. Inoculate a heap on the surface of the prey 19. As a result, the hatching rate of the larvae 50 that hatch from the inoculated eggs 49 can be improved, and the survival rate of the larvae 50 can be improved.

In the egg/larva inoculation means (egg/larva inoculation step), a plurality of housefly eggs 49 are inoculated on the surface of a predetermined medium in a state of being evenly spaced and inoculated in a heap, and first-instar larvae immediately after hatching from the eggs 49. 50a is collected, and the prey 19 is inoculated with the first-instar larva 50a. Alternatively, a plurality of housefly eggs 49 are inoculated on a surface of a predetermined medium in a state of being equally spaced, and the first instar larva 50a immediately after hatching from the eggs 49 is prepared by a prey preparation means (prey preparation step). The prepared prey 19 is fed to grow into larvae that are feeding habits to the prey 19 created by the prey preparation means (prey preparation step), and the second instar larva 50b after one molting is collected from the first instar larva 50a. The second instar larva 50b is inoculated into the prey 19.

In the egg/larva inoculation means (egg/larva inoculation step), the weight ratio of egg 49 to the total weight of prey 19 (inoculation amount of egg 49 to inoculate prey 19) is 0.002% by weight to 0.005% by weight. In range. When the weight ratio (inoculation amount) of the eggs 49 is less than 0.002% by weight, the number of larvae 50 hatched from the eggs 49 is small, the larvae 50 cannot eat most of the prey 19, and the prey 19 remains. However, a large amount of tokara 17 (prey 19) cannot be efficiently processed in a short period of time. When the weight ratio of the eggs 49 (inoculation amount) exceeds 0.005% by weight, the number of larvae 50 hatched from the eggs 49 is too large, the prey 19 is insufficient, and the growth of the larvae 50 is delayed. (Prey 19) cannot be efficiently processed in a short period of time. In the Ooka treatment system 10A (including the Okara treatment system 10B), the weight ratio of the egg 49 to the total weight of the prey 19 is within the above range, and therefore the balance between the prey 19 and the number of larvae 50 hatched from the egg 49 is balanced. Therefore, the larva 50 hatched from the egg 49 does not become short of the prey 19, and the larva 50 hatched from the egg 49 can be used to feed all of the prey 19 in a short time without wasting the egg 49. Therefore, a large amount of tokara 17 (prey 19) can be efficiently processed in a short period of time without the prey 19 remaining.

In the egg/larva inoculation means (egg/larva inoculation step), the inoculation number of the larva 50 per 1 kg of the prey 19 is in the range of 20 to 50. If the number of larvae 50 inoculated to 1 kg of prey 19 is less than 20, the number of larvae 50 to prey 19 is small, the larvae 50 cannot eat most of the prey 19, the prey 19 remains, and the large amount of prey 19 remains. To 17 (prey 19) cannot be efficiently processed in a short period of time. If the number of larvae 50 inoculated exceeds 50, the larvae 50 will be oversupplied, the prey 19 will be insufficient and the growth of the larvae 50 will be delayed, and a large amount of Okara 17 (prey 19) will be efficiently treated in a short period of time. I can't. In the Ooka treatment system 10A (including the Okara treatment system 10B), the number of inoculations of the larva 50 to 1 kg of the prey 19 is within the above range, so that the numbers of the prey 19 and the larva 50 are balanced, and the larva 50 is the prey. The larva 50 can be used to feed all of the prey 19 in a short time without causing a shortage, and a large amount of tokara 17 (prey 19) can be efficiently processed in a short time without the prey 19 remaining. be able to.

After the eggs 49 are inoculated into the prey 19 or the larvae 50a and 50b are inoculated into the prey 19, the prey storage trays 20 are vertically stacked by the elevating lifter 14 to form the breeding floor 15 having a hierarchical structure. As shown in FIG. 2, a plurality of breeding floors 15 are housed in an internal airtight space 21 of a breeding chamber 16 (a processing space having a predetermined volume). Rails (not shown) are laid in the breeding room 16, the wheels of the breeding floor 15 are fitted to the rails, and the breeding floor 15 is fixed to the breeding room 16 so that it can travel.

When the breeding floor 15 is housed in the internal airtight space 21 of the breeding room 16, the light emitting device 26 of the lighting equipment is above the breeding floor 15 and the front end portions of the front and rear portions 34, 35 of the prey storing tray 20 located at the top. It is located near 37 and 41. In FIG. 2, three breeding floors 15 are housed in the breeding room 16, but the number of breeding floors 15 is not particularly limited, and four or more breeding floors 15 may be housed in the breeding room 16. After housing the breeding floor 15 in the breeding room 16, the door is closed and the door is locked. When the breeding floor 15 is housed in the breeding room 16, the air conditioning equipment, lighting equipment, controller, temperature sensor, humidity sensor, illuminance sensor, and room pressure sensor are operating.

The controller maintains the temperature of the internal airtight space 21 of the breeding room 16 at the set temperature via the air conditioning equipment while comparing the measured temperature (temperature signal) output from the temperature sensor with the set temperature, and outputs from the humidity sensor. While comparing the measured humidity (humidity signal) and the set humidity, the humidity of the airtight space 21 is maintained at the set humidity via the air conditioning equipment. Further, the side illuminance (illuminance signal) output from the illuminance sensor is compared with the set illuminance, and the illuminance of the airtight space 21 is maintained at the set illuminance through the lighting equipment. The controller adjusts the brightness of the internal airtight space 21 according to the time of sunrise and sunset 24 hours a day, and switches the airtight space 21 to darkness (night) or sunshine (daytime).

At the time of inoculation of the house fly egg 49 into the prey 19 (after inoculation of the house fly egg 49 into the prey 19 until hatching into the larva 50 from the egg 49), the controller controls the internal airtight space 21 (treatment) of the breeding room 16. The temperature of the space) is maintained in the range of 20 to 50°C (preferably 20 to 40°C), and the humidity of the internal airtight space 21 (treatment space) is set to 60 to 100% (preferably 60 to 90%). Hold. When the temperature of the internal airtight space 21 is less than 20° C. and the humidity is less than 60%, hatching of the eggs 49 is delayed, and a large amount of tokara 17 (prey 19) cannot be efficiently processed in a short period of time. When the temperature of the internal airtight space 21 exceeds 50° C., the hatching rate of the eggs 49 decreases due to heat, the number of larvae 50 decreases, and the appetite (feeding) of the larvae 50 decreases, resulting in a large amount of okara 17. (Prey 19) cannot be efficiently processed in a short period of time.

The Okara treatment system 10A (including the Okara treatment system 10B) is used for inoculation of the housefly egg 49 into the prey 19 (after inoculation of the housefly egg 49 into the prey 19 and before hatching of the larva 50 from the egg 49). While maintaining the temperature of the internal airtight space 21 (treatment space) of the breeding room 16 in the range of 20 to 50° C. (preferably 20 to 40° C.), the humidity is 60 to 100% (preferably 60 to). 90%) makes it possible to create an optimal hatching environment for housefly eggs 49, so that the hatching rate of larvae 50 that hatch from inoculated eggs 49 can be improved, and hatching due to environmental deterioration It is possible to prevent the rate from decreasing. The loose treatment system 10A (including the okara treatment system 10B) can not only ensure the survival of the egg 49 during the hatching process of the housefly egg 49 and improve the hatching rate of the egg 49, Using the larva 50, a large amount of tokara 17 (prey 19) can be efficiently treated in a short period of time.

Immediately after hatching from eggs 49 to larvae 50 (first-instar larvae 50a), or at the time of inoculation of prey 19 with larvae 50 (first-instar larvae 50a or second-instar larvae 50b) (raising process of larvae 50), the controller raises them. The temperature of the internal airtight space 21 (processing space) of the chamber 16 is maintained in the range of 20 to 50°C (preferably 20 to 40°C), and the humidity of the internal airtight space 21 (processing space) is in the range of 65 to 80%. Hold on. When the temperature of the internal airtight space 21 is less than 20° C. and the humidity is less than 65%, an optimal environment for the growth of the larvae 50 cannot be created, and the appetite (feeding) of the larvae 50 is reduced, resulting in the larvae 50. Growth is delayed, and a large amount of tokara 17 (prey 19) cannot be efficiently treated in a short period of time. When the temperature of the internal airtight space 21 exceeds 50° C. and the humidity exceeds 80%, an optimal environment for the growth of the larva 50 cannot be created, and the appetite (feeding) of the larva 50 decreases, and the larva Growth of 50 is delayed and large amount of tokara 17 (prey 19) cannot be efficiently treated in a short period of time.

The Okara treatment system 10A (including the Okara treatment system 10B) is used as a prey for the larva 50 (1st instar larva 50a or 2nd instar larva 50b) immediately after hatching from the egg 49 to the larva 50 (1st instar larva 50a) 19. By keeping the temperature of the internal airtight space 21 (treatment space) in the range of 20 to 50° C. (preferably 20 to 40° C.) and the humidity in the range of 65 to 80% during inoculation of the housefly, Since an optimal breeding environment for the larvae 50 can be created, the larvae 50 can be prevented from dying due to environmental deterioration, the survival rate of the larvae 50 can be improved, and the appetite (feeding) of the larvae 50 can be improved. The growth of the larvae 50 can be promoted. The Okara treatment system 10A (including the Okara treatment system 10B) can surely make the larva 50 survive in the growth process of the housefly larva 50, and not only can improve the survival rate of the larva 50, Using the larva 50, a large amount of tokara 17 (prey 19) can be efficiently treated in a short period of time.

In the prey storage tray 20 stored in the internal airtight space 21 (treatment space) of the breeding room 16, eggs 49 are inoculated into the prey 19 (okara 17), and the larvae 50 hatch from the eggs 40 on the first day. The larvae 50 hatched from the eggs 49 are the first instar larvae 50a immediately after hatching, the second instar larvae 50b after one molting from the first instar larvae 50a, and the second instar larvae 50a after two moltings (from the second instar larvae 50b to 1 It is divided into 3rd instar larvae 50c before pupal metamorphosis (after molting). The 1st instar larva 50a is the larva 50 from the second day after inoculation of the egg 49 into the prey 19 and the second instar larva 50b is the first day after the second day from the inoculation of the egg 49 into the prey 19 Larvae 50 up to the eye (3 days after inoculation of egg 49 into prey 19). The 3rd instar larva 50c is from the first day to the third day after the third day after inoculation of the egg 49 into the prey 19 (from the fourth day to the seventh day after inoculation of the egg 49 into the prey 19). 50 larvae. The larvae 50a to 50c grow in a short period of time by using the prey 19 (Okara 17, rice husk 18a, crushed vegetable waste 18b) stored in the prey storage tray 20 as food.

In the okara treatment system 10A, the prey 19 (okara 17) is fed to the larvae 50a to 50c to raise the larvaes 50a to 50c, and the larvae 50a to 50c grow on the prey 19 as a food. When the larvae 50a to 50c are enzymatically decomposed in the body and excreted from the larvae 50a to 50c, the prey 19 (okara 17) is changed to a decomposition product 51 (low-concentration organic decomposition product) of the prey 19 (prey-decomposition means). (Prey decomposition process)), (Larvae breeding means (larva breeding process)). The decomposition product 51 of the prey 19 is used as a fertilizer base material for organic fertilizer. In the prey decomposition means (prey decomposition step), air (oxygen) is supplied to the internal airtight space 21 (processing space) of the breeding room 16 by the air supply fan 23, and the air in the internal airtight space 21 (processing space) is exhausted by the exhaust fan. It is exhausted to the outside (atmosphere) by 25. It should be noted that impurities, miscellaneous bacteria, and viruses contained in the air are collected by the medium-performance filter and the HEPA filter, and clean air is supplied to the internal airtight space 21 of the breeding room 16.

In an example of the prey decomposition means (prey decomposition step), as shown in FIG. 6, the first instar larvae 50a are reared in the dark in the rearing room 16 (internal airtight space 21) in the dark (first rearing means (first rearing step). )), the second-instar larva 50b is bred in the twilight breeding room 16 (internal airtight space 21) in the twilight (second breeding means (second breeding step)), and the bright breeding room 16 (internal airtight space 21). In 3), the third instar larvae 50c are reared in the light (third rearing means (third rearing step)).

In the first breeding means (first breeding step), the controller does not turn on the lighting equipment until the second day (two days have passed) after inoculating the egg 49 or immediately after hatching from the egg 49. From the egg 49 to the 1st instar larva 50a, the breeding room 16a (inner airtight space 21) is kept dark until the first day (1 day has passed) after inoculation of the 1st instar larva 50a without turning on the lighting equipment. Breed in the dark (at night). The breeding room 16 has a structure that does not allow light to enter from the outside. In the first breeding means (first breeding step), the controller supplies the air supply fan 22 and the exhaust air so that the room pressure of the internal airtight space 21 of the breeding room 16 becomes the first set room pressure (approximately the same pressure as the atmospheric pressure). The output of the fan 24 is adjusted, air (oxygen) is supplied to the internal airtight space 21 (treatment space) of the breeding room 16 by the air supply fan 22, and air is exhausted from the internal airtight space 21 (atmosphere) by the exhaust fan 24. The chamber pressure of the internal airtight space 21 of the breeding chamber 16 is maintained at substantially the same pressure (±0 Pa) as the atmospheric pressure while being exhausted.

The loose treatment system 10A (including the okara treatment system 10B) breeds the first-instar larvae 50a in the dark (darkness) (at night) in the first breeding means (first breeding step), and at the same time, the first-instar larvae 50a. Is maintained at approximately the same pressure as the atmospheric pressure, the oxygen necessary for the growth of the first-instar larva 50a is supplied without stimulating the first-instar larva 50a with light, and the first-instar larva 50a moves downward from the prey 19. It is possible to prevent burrowing and hiding inside the prey 19 and feed the first instar larva 50a from the surface of the prey 19 and the first instar larva 50a to the second instar as scheduled (deadline). The larvae 50b can be reared.

In the second breeding means (second breeding step), the controller is on the first day (one day has elapsed) after the second day after inoculating the egg 49 (the third day after inoculating the egg 49). Or, from the inoculation of the 2nd instar larva 50b to the 1st day (1 day has passed), the illumination facility is turned on while adjusting the illuminance of the illumination facility to make the breeding room 16b dim, and the 2nd instar larva 50b. Breed in dim light. In the second breeding means (second breeding step), the controller controls the air supply fan 22 and the exhaust fan 24 so that the chamber pressure of the internal airtight space 21 of the breeding chamber 16 becomes the second set chamber pressure (slightly positive pressure). The output is adjusted, air (oxygen) is supplied to the internal airtight space 21 (treatment space) of the breeding room 16 by the air supply fan 22, and the air is exhausted from the internal airtight space 21 to the outside (atmosphere) by the exhaust fan 24. Meanwhile, the room pressure of the internal airtight space 21 of the breeding room 16 is maintained at a slight positive pressure (+0.1 Pa to +0.5 Pa). The Okara treatment system 10A (including the Okara treatment system 10B) raises the 2nd-instar larva 50b in the dim light (sunrise and sunset) and the 2nd-instar larva 50b at a slight positive pressure.

From the 4th day to the 7th day after that, the lighting equipment is turned on while adjusting the illuminance of the lighting equipment to brighten the breeding room 16c (the internal airtight space 21) (in the daytime state), and the 3rd instar larva 50c Keep in the light. The light from the lighting equipment illuminates the front end portions 37, 41 of the front and rear portions 34, 35 of the prey storage tray 20, and moves to the front end portions 37, 41 of the front and rear portions 34, 35 of the storage tray 20 for the third instar larva 50c. Facilitate.

In the third breeding means (third breeding step), the controller outputs the air supply fan 22 and the exhaust fan 24 so that the room pressure of the internal airtight space 21 of the breeding room 16 becomes the third set room pressure (positive pressure). The air supply fan 22 supplies air (oxygen) to the internal airtight space 21 (treatment space) of the breeding room 16, and the exhaust fan 24 exhausts the air from the internal airtight space 21 to the outside (atmosphere). The room pressure of the internal airtight space 21 of the breeding room 16 is maintained at a positive pressure (+1 Pa to +3 Pa), and the internal airtight space 21 of the breeding room 16 is maintained in an aerobic atmosphere (excess oxygen atmosphere).

After the larva 50 eats the prey 19 (Okara 17), the larva 50 becomes the third-instar larva 50c, and the pupa metamorphosis time comes. The third instar larva 50c has a discrete habit (peristaltic discrete habit) when it undergoes pupal metamorphosis, and actively peristaltes in search of a place to become a pupa. Okara treatment system 10A (including Okara treatment system 10B) raises the 3rd instar larva 50c in the light (daytime state) and the 3rd instar larva 50c by positive pressure (aerobic atmosphere).

In another example of the prey decomposition means (prey decomposition step), the first day of a natural one-day (24 hours) cycle (sunrise (light)→daytime (light)→sunset (light)→night (dark)) Larvae 50a to 3rd instar larvae 50c are bred. The controller operates until the second day (2 days has elapsed) after inoculation with the egg 49 or the first day (1 day has elapsed) after inoculation of the 1st instar larva 50a immediately after hatching from the egg 49. In the meantime, while adjusting the illuminance of the lighting equipment (issuing device 26) according to the cycle of the natural day (24 hours), the lighting equipment is turned on and the lighting equipment is turned off, and the natural day (24 hours) The first-instar larvae 50a are reared in a cycle (sunrise (light)→daytime (light)→sunset (light)→night (dark)) (first rearing means (first rearing step)).

In the first breeding means (first breeding step), the controller supplies the air supply fan 22 and the exhaust air so that the room pressure of the internal airtight space 21 of the breeding room 16 becomes the first set room pressure (approximately the same pressure as the atmospheric pressure). The output of the fan 24 is adjusted, air (oxygen) is supplied to the internal airtight space 21 (treatment space) of the breeding room 16 by the air supply fan 22, and air is exhausted from the internal airtight space 21 (atmosphere) by the exhaust fan 24. The chamber pressure of the internal airtight space 21 of the breeding chamber 16 is maintained at substantially the same pressure (±0 Pa) as the atmospheric pressure while being exhausted (ventilated).

The okara treatment system 10A (including the okara treatment system 10B) raises the first-instar larvae 50a in a cycle of 1 day (24 hours) in the first rearing means (first rearing step), and the first-instar larvae 50a. Is maintained at about the same pressure as the atmospheric pressure, the first-instar larva 50a is raised in the same environment as the natural environment, and oxygen necessary for the growth of the first-instar larva 50a is supplied to grow the first-instar larva 50a. The 1st instar larva 50a can be reliably fed with the prey 19 (Okara 17), and the 1st instar larva 50a can be reared to the 2nd instar larva 50b as scheduled (deadline).

The controller, until the first day (one day has elapsed) after the second day of inoculation with the egg 49 (the third day after the inoculation of the egg 49) or the second instar larva 50b is inoculated. From the 1st to 1st day (1 day has passed), while adjusting the illuminance of the lighting equipment (light emitting device 26) according to the cycle of a natural day (24 hours), the lighting equipment is turned on and the lighting equipment is turned off. Then, the second instar larvae 50b are reared in a natural 1-day (24 hours) cycle (sunrise (light)→daytime (light)→sunset (light)→night (dark)) (second rearing means (second rearing means (second)). 2 Breeding process)).

In the second breeding means (second breeding step), the controller controls the air supply fan 22 and the exhaust fan 24 so that the chamber pressure of the internal airtight space 21 of the breeding chamber 16 becomes the second set chamber pressure (slightly positive pressure). The output is adjusted, air (oxygen) is supplied to the internal airtight space 21 (treatment space) of the breeding room 16 by the air supply fan 22, and the air is exhausted from the internal airtight space 21 to the outside (atmosphere) by the exhaust fan 24 ( Ventilation) while maintaining the room pressure of the internal airtight space 21 of the breeding room 16 at a slight positive pressure (+0.1 to +0.5 Pa).

The okara treatment system 10A (including the okara treatment system 10B) raises the second instar larva 50b in a cycle of one day (24 hours) in the second rearing means (second rearing step), and the second instar larva 50b. By raising the 2nd instar larva 50b in the same environment as the natural environment, the oxygen necessary for the growth of the 2nd instar larva 50b is supplied to activate the peristalsis of the 2nd instar larva 50b. Along with promoting the growth of the 2nd instar larva 50b, the 2nd instar larva 50b can be reliably fed with the prey 19 (Okara 17), and the 2nd instar larva 50b is bred to the 3rd instar larva 50c as scheduled (deadline). be able to.

From the first day (1 day elapsed) to the 3rd day (3 days elapsed) after the third day after inoculating the egg 49, the controller (fourth to seventh days after inoculating the egg 49) During the period, while adjusting the illuminance of the lighting equipment (light emitting device 26) according to the cycle of the natural day (24 hours), the lighting equipment is turned on and the lighting equipment is turned off, and the natural day (24 hours) The third-instar larvae 50c are bred in the cycle (sunrise (light)→daytime (light)→sunset (light)→night (dark)) (third breeding means (third breeding step)).

In the third breeding means (third breeding step), the controller outputs the air supply fan 22 and the exhaust fan 24 so that the room pressure of the internal airtight space 21 of the breeding room 16 becomes the third set room pressure (positive pressure). The air supply fan 22 supplies air (oxygen) to the internal airtight space 21 (treatment space) of the breeding room 16, and the exhaust fan 24 exhausts the air from the internal airtight space 21 to the outside (atmosphere). While maintaining the room pressure of the internal airtight space 21 of the breeding room 16 at a positive pressure (+1 Pa to +3 Pa), the internal airtight space 21 of the breeding room 16 is maintained in an aerobic atmosphere (excess oxygen atmosphere). After the larva 50 eats the prey 19 (Okara 17), the larva 50 becomes the third-instar larva 50c, and the pupa metamorphosis time comes. The third instar larva 50c has a discrete habit (peristaltic discrete habit) when it undergoes pupal metamorphosis, and actively peristaltes in search of a place to become a pupa.

The okara treatment system 10A (including the okara treatment system 10B) raises the 3rd instar larva 50c in a cycle of 1 day (24 hours) in the third rearing means (third rearing step) and the 3rd instar larva 50c. By raising the larvae under positive pressure (aerobic atmosphere), the third-instar larva 50c is reared in the same environment as the natural environment while supplying oxygen necessary for the growth of the third-instar larvae 50c, and the peristalsis of the third-instar larvae 50c. Can be activated and the growth of the third instar larva 50c can be promoted, and the third instar larva 50c can be surely fed with the prey 19 (Okara 17).

Okara treatment system 10A (including Okara treatment system 10B) mixes a predetermined amount of okara 17 with a predetermined amount of agricultural waste 18 (rice husk 18a, crushed vegetable waste 18b) to obtain a predetermined amount of okara. By dispersing a predetermined amount of the agricultural waste 18 inside 17, the housefly larva 50 creates a predetermined amount of prey 19 having a void that facilitates peristalsis, and prey stored in the prey storage tray 20 (prey storage container). 19 were inoculated with a plurality of housefly eggs 49, or prey 19 housed in a prey storage tray 20 was inoculated with housefly larvae 50a and 50b, and eggs 49 were inoculated into a plurality of hatched larvae 50a or prey. The larvae 50a and 50b are allowed to grow by allowing the larvae 50a to 50c to feed the prey 19 while causing the voids of the prey 19 to be accommodated in the prey accommodation tray 20 to perturb. Since the prey 19 is enzymatically decomposed in the body of the larvae 50a to 50c in the process, the feeding habits of the housefly larvae 50a to 50c, which prefer to eat the prey 19 eaten first, are utilized, and the appetite of the larvae 50a to 50c (feeding) It is possible to efficiently treat a large amount of Okara 17 (prey 19) in a short period of time while promoting

The okara treatment system 10A (including the okara treatment system 10B) forms a void in the prey 19 by the agricultural waste 18 (rice husk 18a, crushed vegetable waste 18b), and a plurality of larvae 50a hatched from eggs 49 or Since the larvae 50b inoculated into the prey 19 are peristaltic in the space, the larvae 50a to 50c can easily peristalize inside the prey 19 and activate the peristaltic habits of the housefly larvae 50a to 50c to activate the larvae 50a to The appetite of 50c can be enhanced, and a large amount of tokara 17 (prey 19) can be fed to the larvae 50a to 50c in a short period of time. Okara treatment system 10A (including Okara treatment system 10B) utilizes Okara 17 (prey 19) in the body of housefly larvae 50a to 50c, and thus utilizes the food habits of housefly larvae 50a to 50c. Therefore, a large amount of tokara 17 (prey 19) can be safely and inexpensively processed.

The okara treatment system 10A (including the okara treatment system 10B) can add a proper amount of the rice husks 18a and the vegetable scraps 18b to the okara 17 to form a proper gap in the prey 19, so that the larvae can be made. 50a to 50c can easily peristalize inside the prey 19, and can activate the peristaltic habits of the housefly larvae 50a to 50c, and the vegetable scraps 18b enhance the appetite (food habit) of the larvae 50a to 50c. It becomes an appetite (feeding) enhancer and can enhance the appetite of the larvae 50a to 50c. Due to the active peristalsis of the housefly larvae 50a to 50c and the vigorous appetite of the larvae 50a to 50c, a large amount of (Prey 19) can be efficiently processed in a short period of time.

The prey 19 is eaten by the larvae 50 and the larvae 50 grow, and the larvae become the 3rd instar larvae 50c, and the pupa metamorphosis time comes. The 3rd instar larva 50c has a discrete habit (peristaltic discrete habit) when it undergoes pupal metamorphosis (the 3rd instar larva 50c which has reached the pupal metamorphosis time). The third-instar larva 50c, which has reached the pupa metamorphosis stage, is illuminated by lighting equipment (fluorescent lamp 26, LED lighting 26). The 3rd instar larva 50c, which has reached the pupa metamorphosis stage, actively peristalticly separates in search of a place where it will become a pupa, and while moving around the bottom plate 31 of the prey storage tray 20, its lighting performance (fluorescent lamp 26, LED lighting 26) ), climbs up the slopes 38 and 42 from the central portion 33 of the bottom plate 31 and moves from the central portion 33 toward the tip portions 37 and 41 of the front and rear portions 34 and 35. The third instar larva 50c that has moved to the tip portions 37, 41 of the front and rear portions 34, 35 of the prey storage tray 20 enters the slopes 38, 42 between the convex portions 39, 43 formed on the tip portions 37, 41, and It further climbs up the slopes 38 and 42, gets over the tips of the tip portions 37 and 41, and drops from the tips toward the collection container 27 as shown in FIG.

The third-instar larva 50c heading from the central portion 33 of the bottom plate 31 toward both side plates 32 hits the partition plate 48 and crawls along the partition plate 48 from the central portion 33 of the bottom plate 31 to the slopes 38, 42 to reach the central portion. It moves from 33 toward the tip portions 37, 41 of the front and rear portions 34, 35, gets over the tips of the tip portions 37, 41 and drops toward the collection container 27. Or, it abuts on both side plates 32 and crawls up the slopes 38, 42 from the central portion 33 of the bottom plate 31 along the both side plates 32, and moves from the central portion 33 toward the tip portions 37, 41 of the front and rear portions 34, 35, It goes over the tips of the tip portions 37, 41 and falls toward the collection container 27.

In the okara treatment system 10A (including the okara treatment system 10B), the third-instar larva 50c that has reached the pupal metamorphosis time is transferred from the tips of the front and rear portions 34, 35 of the prey storage tray 20 to the collection containers 27. Since it falls, the larva 50c and the decomposition product 51 are separated using the discrete habit of the 3rd instar larva 50c (peristaltic discrete habit) (sorting means (sorting step)). The okara treatment system 10A (including the okara treatment system 10B) separates the larva 50c and the decomposed product 51 without human intervention by utilizing the discrete habit of the 3rd instar larva 50c (peristaltic discrete habit). be able to. In addition, by illuminating the 3rd instar larva 50c that has reached the pupa metamorphosis time from the lighting equipment (fluorescent lamp 26, LED illumination 26), the photocatalyst of the 3rd instar larva 50c is utilized to separate the larva 50c and the decomposed product 51. It can be reliably separated.

In the okara treatment system 10A (including the okara treatment system 10B), the separation of the third-instar larva 50c and the decomposition product 51 (low-concentration organic decomposition product) starts on the fourth day after inoculating the prey 19 with the egg 49. On the 7th day, starting on the 3rd day and ending on the 6th day after inoculation of the 1st instar larva 50a. Alternatively, the prey 19 is inoculated with the second-instar larva 50b, and starts on the second day and ends on the fifth day. Therefore, the egg 49 grows into the third instar larva 50c before pupal metamorphosis in a maximum of 7 days. In the okara treatment system 10A (including the okara treatment system 10B), an insect food raw material is prepared from a group of the third instar larvae 50c (third instar larvae group) separated from the decomposed product 51 (insect food raw material preparation means (insect food). Raw material preparation process)). Alternatively, a feed raw material for a domestic animal is produced from a group of third-instar larvae 50c (third-instar larvae group) separated from the decomposed product 51 (feed raw material producing means (feed raw material producing step)).

In the insect food raw material preparation means (insect food raw material preparation step) and the feed raw material preparation means (feed raw material preparation step), the third-instar larvae 50c are subjected to hot water treatment (boil treatment), dehydration treatment, and frozen and stored. Alternatively, the third-instar larvae 50c are subjected to hot water treatment (boil treatment), dehydration treatment, and vacuum packaging. Alternatively, the third-instar larvae 50c are subjected to a hot water treatment (boil treatment), dehydration treatment and drying treatment, and stored at room temperature. Alternatively, the third-instar larvae 50c are subjected to hot water treatment (boil treatment), dehydration treatment, drying treatment, powder treatment, and stored at room temperature. The insect food raw material produced by the insect food raw material preparation means (insect food raw material preparation step) becomes an insect food ingredient. The feed raw material produced by the feed raw material producing means (feed raw material producing step) serves as a raw material for the feed for the domestic animal.

Okara treatment system 10A (including Okara treatment system 10B) can feed housefly larva 50 with clean tokara 17 to convert housefly larva 50 into an edible insect food ingredient. 17 can be effectively used without waste. Since the okara treatment system 10A (including the okara treatment system 10B) can make an insect food raw material by using the okara 17 that has been discarded so far, it is used for the insect food from the discarded okara 17 Insect food raw materials can be obtained, and food shortages that occur in the future can be supplemented by housefly larvae 50 and Okara 17. It should be noted that the insect food material contains high protein and abundant chitosan, and by eating an insect food made from the insect food material, the immunity and natural healing power can be enhanced.

The okara treatment system 10A (including the okara treatment system 10B) can change the housefly larva 50 into a feed material for a domestic animal by feeding the housefly larva 50 with the okara 17. Can be effectively used without waste. The okara treatment system 10A (including the okara treatment system 10B) can use the okara 17 that has been discarded so far to produce a feed material for farm animals. It is possible to obtain the feed raw material to be fed to the animal, and the deficiency of the feed raw material for the fed animal that occurs in the future can be supplemented by the housefly larvae 50 and Okara 17. It should be noted that the feed raw material contains high protein and abundant chitosan, so that it is possible to enhance the immunity and natural healing power of the animal fed with the feed raw material.

In the okara treatment system 10A (including the okara treatment system 10B), the prey 17 is inoculated with the egg 49 from the fifth day onward, and the prey 17 is inoculated with the first instar larva 50a from the fourth day onwards. 1% to 5%, preferably 2% to 3% of the group (3rd instar larvae) of 3rd instar larvae 50c separated from the degradation product 51 on the third day after inoculation of the 2nd instar larvae 50b into The third-instar larvae 50c are collected, and the collected third-instar larvae 50c are bred and transformed from pupae to adults, and the adults are allowed to lay the next-generation eggs, and the eggs are collected to change the generation of houseflies. Perform (housefly breeding means (housefly breeding process)).

In the housefly breeding means (housefly breeding process), the pupae of the third-instar larva 50c collected from the collection container 27 are installed in a breeding facility (not shown) provided inside the building of the Okara treatment plant (inside the plant). While moving to a collection container (not shown) and maintaining the temperature of the pupa collection container at a set temperature (20 to 50°C (preferably 20 to 40°C)) using the air conditioning equipment installed in the breeding facility, The humidity of the pupa collection container is maintained at the set humidity (65 to 80%), and the 3rd instar larva 50c is transformed into pupae.

Next, pupae are collected from the pupa collection container, the pupae are transferred to a breeding gauge (not shown) installed in a breeding facility, and the temperature of the breeding gauge is set to a set temperature (20 to 50°C ( Preferably, the humidity of the breeding gauge is maintained at a set humidity (65 to 80%) while maintaining the temperature of 20 to 40° C.), and the pupae are hatched by adult houseflies. In the housefly breeding means (housefly breeding process), food (milk) is given to the adult housefly after hatching, and the housefly is bred while the adult housefly is laid and the next-generation egg is collected. By inoculating the prey 19 (Okara 17) with the next-generation egg 49 and the larva 50 hatched from the egg 49, the larva 50 hatched from the next-generation egg 49 is treated with Okara 17.

The okara treatment system 10A (including the okara treatment system 10B) causes the female adults, who have grown a part of the group of the third instar larvae 50c (third instar larvae group), to lay the next-generation eggs, and then from the eggs. Since the hatched larvae 50 are used to treat the prey 19 (Okara 17), it is not necessary to newly procure house fly eggs from the outside, and the housefly can be used in a semi-permanent cycle. Can be processed at low cost, and at the same time, it is possible to produce insect food materials and feed materials at low cost.

FIG. 13 is a schematic configuration diagram of an okara processing system 10B shown as another example. The okara treatment system 10B of FIG. 13 is different from that of FIG. 1 in that the disaccharide is mixed into the prey 19 in the prey preparation means (prey preparation step), and other configurations are the okara treatment of FIG. Since it is the same as the system 10A, the same reference numerals as those in FIG. 1 are attached, and the description of FIG. 1 is cited, and the detailed description of the other configuration of the system 10B is omitted.

The okara treatment system 10B of FIG. 13 uses the okara temporary storage box, the stirrer 11, the constant amount cutting machine 12, the belt conveyor 13, the lifting lifter 14, the breeding floor 15, and the breeding room 16 to process the okara of FIG. Similar to the system 10A, sterilization means (sterilization step), prey preparation means (prey preparation step), prey accommodation means (prey accommodation step), egg/larva inoculation means (egg/larva inoculation step), prey decomposition means ( Larva rearing means) (prey decomposition process), sorting means (sorting step), housefly rearing means (housefly rearing step), insect food raw material preparation means (insect food raw material preparation step), feed raw material preparation means (feed raw material preparation step) Implement each means (each step). Sterilization treatment means (sterilization treatment step), prey storage means (prey storage step), egg/larva inoculation means (egg/larva inoculation step), prey decomposition means (larva rearing means) (prey decomposition step), separation means (sorting step) ), a housefly breeding means (housefly breeding process), an insect food raw material creating means (insect food raw material creating process), and a feed raw material creating means (feed raw material creating process), each means (each process) of the Okara treatment system 10A in FIG. ) Is the same.

Okara 17 and rice husks 18a and vegetable shavings 18b, which have been subjected to the sterilization treatment means (sterilization treatment step), are put into the agitator 11 from a sterilization plant or a pulverizer by a belt conveyor (not shown), and a predetermined amount. The disaccharide 52 of (2) is charged into the stirrer 11 (water may be added in some cases). Okara 17, rice husk 18a, crushed vegetable waste 18b, and disaccharide 52 are stirred and mixed in the stirrer 11 to form the prey 19 (prey preparation means (prey preparation step)). In the prey preparation means (prey preparation step), the housefly larvae 50 are easily peristaltic by mixing and dispersing a predetermined amount of rice husks 18a and vegetable scraps 18b (agricultural waste) in the predetermined amount of tokara 17. Voids are formed. As the disaccharide 52, at least one of sucrose, lactulose, lactose, maltose, trehalose, and cellobiose is used (preferably trehalose).

In addition, the okara 17, excluding the crushed vegetable scraps 18b, the rice husk 18a, and the disaccharide 52 are charged into the stirrer 11 (water may be added in some cases), and the okara 17, the rice husk 18a, and the disaccharide 42 are stirred in the stirrer 11. May be mixed with stirring to form the prey 19 (prey preparation means (prey preparation step)). In addition to okara 17, chaff 18a, crushed vegetable scraps 18b, and disaccharide 52, sake lees, stepped lees, mirin lees, coffee lees, shochu lees, beer lees, rapeseed lees, pine lees, tea lees, wine lees, wine lees, At least one of the starch meal may be charged into the stirrer 11 (water may be added in some cases), and in the stirrer 11 they may be stirred and mixed to form the prey 19 (prey preparation means (prey preparation step)). ..

The weight ratio of the agricultural waste 18 to the total weight of the prey 19 is in the range of 5% by weight to 10% by weight as in the case of the okara processing system 10A in FIG. The water content of the tofu 17 fed to the housefly larvae 50 is adjusted in the range of 60% to 80% by the agricultural waste 18 like the okara treatment system 10A of FIG. The weight ratio of the disaccharide 52 to the total weight of the prey 19 is in the range of 1% to 3% by weight. If the weight ratio of the disaccharide 52 is less than 1% by weight, the amount of sugar contained in the prey 19 (okara 17) is small, and an appropriate amount of sugar cannot be added to the okara 17 (prey 19). The larva 50 that ate the (prey 19) cannot contain an appropriate amount of sugar. When the weight ratio of the disaccharide 52 exceeds 3% by weight, the amount of sugar contained in Okara 17 (prey 19) is too large, and the larva 50 consuming Okara 17 (prey 19) contains excessive sugar. Get lost.

Okara processing system 10B of FIG. 13 has the following effects in addition to the effects of Okara processing system 10A of FIG. Okara treatment system 10B mixes Okara 17 with at least one of disaccharide 52 (sucrose, lactulose, lactose, maltose, trehalose, cellobiose, preferably trehalose) to produce Okara 17 (prey 19 ), an appropriate amount of sugar can be added, and the larva 50 that has eaten Okara 17 (prey 19) contains sugar, and the housefly larva 50c can be converted into an insect-containing edible raw material containing sugar. Thus, the housefly larvae 50c can be converted into a feed material for feed animals containing sugar. Since the insect food raw material contains sugar and abundant chitosan, it is possible to make an insect food with high protein and nutritive value. Since the feed raw material contains sugar and abundant chitosan, high protein and nutritive value can be obtained. It can make high feed ingredients.
