Description

Larvae breeding device using food waste {CATERPILLAR BREEDING DEVICE USING FOOD WASTE}

The present invention relates to larva rearing device technology using food waste.

Organic waste, such as food waste from homes and restaurants, organic waste from industrial sites, livestock waste and human waste from livestock farms, etc., causes serious natural environmental problems in soil and rivers when discharged without treatment.

Conventionally, organic waste was mainly used to recycle organic waste as livestock feed or compost through a specific treatment process, while landfilling it in a certain area or dumping it in the ocean. In this case, the problem of very low economic feasibility in terms of installation and maintenance costs of the processing device was revealed.

In order to solve the above conventional problems, organic waste treatment devices are being developed using living organisms such as earthworms and housefly larvae. In this case, the discharged fecal soil is highly ineffective and is useful for cultivation of agricultural land, horticulture, orchards, etc. It can be used effectively and is known to play a role in increasing the growth of plants and the yield of products.

Because black soldier fly larvae have a longer period of time to decompose organic waste than earthworms or houseflies, it is much more effective to raise and use black soldier fly larvae.

Referring to FIG. 1, a larva rearing device using food waste according to an embodiment of the present invention may include a larva growth chamber 100, a discharge pipe 200, and a filter unit 300.

Although the present invention is described for black soldier flies, the present invention is not limited to black soldier flies and can be equally applied to other insects that can decompose organic waste.

The larva growth room 100 is a space where organic waste is supplied to grow insect larvae 10. The larva growth chamber 100 can grow larvae 10 using food waste.

Black soldier flies are insects belonging to the Diptera family Stratiomyidae. Their larvae are carnivorous or herbivorous and live in various habitats (water, rotten organic matter, vegetables, etc.). In other words, the larvae of black soldier flies can decompose food waste.

Black soldier flies are not pests, and unlike common flies, adult flies do not harm humans. Additionally, the adult mouthparts are unique and do not regurgitate after feeding, so they do not transmit disease.

Black soldier fly larvae generate almost no odor, methane gas, or CO2 gas when decomposing organic waste resources (food waste, livestock manure, agricultural product residues, etc.), and can reduce the occurrence of houseflies by 94% when decomposing organic waste resources.

The growth period from egg to adult is 37 to 41 days, and the larvae that can decompose food waste take about 14 to 20 days.

It can be said that one larva has the ability to decompose about 2g of food. For example, if 5,000 black soldier fly larvae are added to 10kg of food waste, more than 80% of the food waste is decomposed in 5 days, and the decomposed food waste decreases by about 42% in volume and weight by about 70% compared to before adding larvae. You can.

Black soldier fly larvae decompose food waste during the 1st to 5th instar larval stages, and when they become old larvae after the 6th instar, they turn brown. As the larvae grow, they change color to white, milky white, or dark brown. Old-aged larvae have a habit of crawling out to find a dry, shady, cool place to pupate.

Black soldier fly larvae (10) can grow up to the stage before pupation in the larval growth room (100).

The larva growth chamber 100 may include a main body with a space therein. The main body may be formed in a box shape, and at least a portion of one side may be open or openable. For example, one side of the main body is open, but it can be slidably coupled to the growth equipment in a drawer style. Alternatively, the main body may be open on one side and may be coupled with a cover that can be opened and closed.

The main body of the larva growth chamber 100 can accommodate organic waste and larvae 10 therein. Larvae (10) can grow by feeding on organic waste. If necessary, more sawdust can be accommodated in the main body of the larva growth chamber 100.

Meanwhile, organic waste may be food waste and/or wet feed made from food waste. Wet feed can be manufactured by heating food waste. However, in the present invention, organic waste is not limited to food waste, and may include various wastes such as animal carcasses.

Organic waste that serves as food for the larvae (10) is supplied periodically, and after the organic waste is supplied, the organic waste and the larvae (10) can be mixed. Larvae (10) can grow and form feces while decomposing organic waste for 14 to 20 days. When the larvae (10) are discharged after 14 to 20 days, they may be discharged together with at least one of sawdust, food waste, and feces.

The discharge pipe 200 is a pipe that discharges the larvae 10 from the larva growth chamber 100. The discharge pipe 200 may be coupled to the main body of the larva growth chamber 100. For example, as shown in FIG. 1, the discharge pipe 200 may be coupled to the side of the main body of the larva growth chamber 100.

The discharge pipe 200 may include a vacuum suction pipe. As the inside of the discharge pipe 200 (vacuum suction pipe) is depressurized, the larvae 10, etc. in the larvae growth chamber 100 can be sucked in. A pressure reducing device 250 is coupled to the discharge pipe 200 (vacuum suction pipe), and according to the operation of the pressure reducing device 250, the discharge pipe 200 (vacuum suction pipe) can suction and transport larvae 10, etc.

As described above, the discharge pipe 200 absorbs feces in addition to the larvae 10. Additionally, the discharge pipe 200 may suck in sawdust and food waste in addition to larvae 10 and feces.

The discharge pipe 200 discharges larvae 10 and the like to the filter unit 300. The filter unit 300 can separate the larvae 10 from feces, etc. (feces, sawdust, food waste) while transporting the larvae 10 discharged from the discharge pipe 200. That is, the filter unit 300 can filter out feces, etc. of the larvae 10 while transporting the discharged larvae 10, etc.

The filter unit 300 may be disposed inclinedly. Larvae 10 discharged to one side of the filter unit 300 may move downward by gravity along the slope of the filter unit 300. As the larvae 10 move along the filter unit 300, feces other than the larvae 10 may be filtered. In Figure 1, larvae 10 are referred to as 10, sawdust and/or food waste are referred to as 20, and feces are referred to as 30.

The larva 10 may move from one side of the filter unit 300 to the other end of the filter unit 300 along the filter unit 300. The larva 10 may temporarily stay at the other end of the filter unit 300 or may be accommodated in the larva receiving unit 430 installed at the rear end of the filter unit 300.

The filter unit 300 may include a mesh-structured filter plate. The pores of the filter plate are smaller than the size of the larva (10). Larvae (10) moving downward along the filter plate do not pass through the pores of the filter plate, but sawdust, food waste, and feces other than the larvae (10) pass through the pores of the filter plate. Therefore, as the larvae (10), etc., move down the filter plate, only the larvae (10) remain on the filter plate, and other feces, etc., may fall away from the larvae (10), pass through the pores of the filter plate, and accumulate under the filter plate. there is.

When the filter unit 300 includes a mesh-structured filter plate, a portion (A) of the filter plate may be formed to have no voids, as shown in FIG. 5(a). The portion (A) of the filter plate in which no pores are formed may be located at the end of the filter plate. Although not shown in the drawing, the portion A of the filter plate without pores may be bent to be flat with the ground.

Meanwhile, voids may be formed throughout the filter plate as shown in Figure 5(b).

In addition, the filter plate of the mesh structure is not flat as shown in FIG. 5, but may have a shape that is convex downward like a semicylindrical column. In this case, the larvae 10 can move downward along the central side of the filter plate, and the sides of the filter plate can act as guides and walls so that the larvae 10 do not fall outward.

The filter unit 300 may vibrate. As the larvae 10, etc. move downward along the filter unit 300, when the filter unit 300 vibrates, it may become easier to separate feces, etc. from the larvae 10. A vibration device is installed in the filter unit 300, and the vibration device can vibrate the filter unit 300 in one direction or multiple directions.

The filter unit 300 may include a feces receiving part 350 that can accommodate feces in addition to the larvae 10. When the filter unit 300 includes a mesh-structured filter plate, the feces receiving unit 350 may be installed below the filter plate.

The feces receiving part 350 is formed to extend to correspond to the length of the filter part 300 (filter plate), and can sufficiently accommodate feces, etc. that are separated as larvae 10, etc., move down the filter part 300. . For example, as shown in FIG. 1, the feces receiving part 350 may be formed to be the same length as the filter part 300.

Referring to FIG. 2, the feces receiving part 350 may be formed shorter than the filter part 300 (filter plate). The filter unit 300 is formed longer than the fecal container 350 so that the larvae 10 can move to the outside of the fecal container 350.

Referring to FIG. 3, the end of the filter unit 300 may be bent and flat with the ground. In this case, the larvae 10 may be loaded on a flat point at the end of the filter unit 300.

The collection unit 400 can collect the larvae 10 from which feces, etc. have been removed by the filter unit 300. The collection unit 400 may include an inhaler 410. The inhaler 410 can inhale the larvae 10 and transport them to another location.

The suction device 410 of the collection unit 400 can inhale the larvae 10 from which feces, etc. have been removed, while the internal pressure is reduced. A decompression device 450 is coupled to the inhaler 410, and according to the operation of the decompression device 450, the inhaler 410 can inhale and transport the larva 10.

The collection unit 400 may further include a post-collection chamber 420. The inhaler 410 can transfer the larvae 10 to the post-collection chamber 420. The post-collection chamber 420 may store the larvae 10 for at least one of washing and packaging the larvae 10.

As shown in FIG. 1, the larvae 10 may be temporarily located at the end 310 of the filter unit 300 and then transferred to the next process by the collection unit 400. That is, the larvae 10 move downward along the filter unit 300 from one side of the filter unit 300, and when located at the other end 310 of the filter unit 300, the inhaler 410 of the collection unit 400 ) can inhale the larvae (10).

As shown in Figure 2, the larvae 10 are temporarily located at the end 310 of the filter part 300 outside the feces receiving part 350 and then can be transferred to the next process by the collection part 400. there is. Here, compared to the case of FIG. 1, the problem of feces contained in the feces containing portion 350 being inhaled by the inhaler 410 may not occur.

As shown in FIG. 3, the larvae 10 may be loaded on the flat end 310 of the filter unit 300 and then transferred to the next process by the collection unit 400. The larva 10 moves downward along the filter unit 300 from one side of the filter unit 300, and when located at the other flat end 310 of the filter unit 300, it may no longer move downward, After being stably loaded, the inhaler 410 of the collection unit 400 can inhale the larvae 10.

Meanwhile, referring to FIG. 4, the collection unit 400 may further include a larva receiving unit 430. The larva receiving unit 430 is installed at the rear end of the filter unit 300 to collect the larvae 10. When the collection unit 400 includes a larva receiving unit 430, the larvae 10 are not sucked directly from the end 310 of the filter unit 300, but are sucked in via the larva receiving unit 430. The filter unit 300 may cause the larvae 10 to fall toward the larvae accommodating part 430, and the larvae 10 may be loaded into the larvae accommodating part 430. That is, the larva 10 may move downward along the filter unit 300 and fall toward the larva receiving unit 430.

The larvae 10 accommodated in the larva receiving unit 430 may be sucked in by the inhaler 410 and transferred to the post-collection chamber 420. The inhaler 410 may be coupled to the side of the larva receiving portion 430, but in the present invention, the coupling position of the inhaler 410 is not limited.

The larva accommodating part 430 may be formed in a box-shaped configuration, and the larva accommodating part 430 may be arranged side by side with the fecal accommodating part 350. To prevent feces detached from the larvae 10 from flowing into the larvae accommodating part 430, the feces accommodating part 350 and the larvae accommodating part 430 may be spaced apart at a predetermined distance.
