Insect breeding system for processing agricultural food by-products {INSECT BREEDING SYSTEM FOR DISPOSING BY-PRODUCTS OF AGRI-FOOD}

The present invention relates to an insect breeding system for processing agro-food by-products using insects that can treat agro-food by-products such as food waste in the process of growth.

Currently, agricultural food by-products such as food waste discharged from homes and restaurants, organic wastes generated from industrial sites, and organic wastes such as livestock manure and human waste generated from barns can cause serious environmental problems such as soil and rivers if discharged without treatment. there is.

According to the conventional method, a method of recycling organic waste as livestock feed or compost through a specific treatment process, a method of landfilling in a certain area or dumping in the sea has been mainly used. In this case, there is a problem of low economic feasibility in terms of installation cost and maintenance cost of the treatment device. In addition, in the case of using the discharged material as feed, side effects such as generation of gangrene are large, and in the case of composting, there are problems such as reheating and ineffective imbalance.

In addition, in order to solve the above problems, organic waste treatment systems using organisms such as earthworms and house fly larvae have been developed. In this case, the discharged fecal soil has excellent inefficiency and can be usefully used for cultivation of farmland, horticulture, orchards, etc., and is known to play a role in increasing the growth of plants and the yield of products.

Among them, Dongae, etc., grows from egg to adult in 37 to 41 days, and the period of larvae serving as decomposers is about 14 days. Dongae larvae have a habit of crawling out to find a dry place to pupate after a period of time (about 14 days) in which organic waste can be decomposed. If 5,000 caterpillars are added to 10 kg of food waste, more than 80% of the food waste is decomposed in 5 days, and the decomposed food waste is reduced by about 42% in volume and about 70% in weight before the larvae are introduced. Black soldier flies have a longer period of time to decompose organic waste than earthworms or house flies, so it is much more effective to breed and use them.

However, organic waste treatment devices using earthworms or flies have problems such as being applied only to a small amount of organic waste generated in homes, odors generated during decay of organic waste, and difficulty in separating fecal soil from larvae.

Therefore, since Dongae larvae can be used not only for processing organic waste but also for animal feed and oil extraction, it is necessary to develop an automatic collection device for homeless larvae that can efficiently breed and multiply them. Therefore, there is a need for an automated processing device capable of reducing labor by developing an automatic larva rearing device for Dongae, etc., which can continuously breed larvae and automatically collect homeless larvae.

On the other hand, in the process of breeding larvae in Dongae, etc., it is necessary to feed agricultural food by-products and treat the decomposed feces when feces occur. At this time, the peculiar odor generated from the breeding container and feces of the larvae of Dongae etc. is released into the air, and this odor gives discomfort to workers or people near the treatment plant. In addition, there is a problem in that a lot of workers' hands are involved in the process of feeding agricultural food by-products, the work of breeding, and the work of handling feces. In particular, manual breeding is difficult to manage 24 hours a day, so it is difficult to properly respond to changes in the breeding environment, there is a problem that mass mortality occurs at too high or low temperatures, and an environment unsuitable for breeding can be created even within the same space.

Therefore, it is necessary to develop a larva breeding device for dongae, etc., which enables unmanned breeding and can minimize the odor emitted to the outside during breeding of larvae in dongae, etc.

The insect breeding system according to the present invention includes a housing 10, an exhaust device 20, a cooling and heating device 30, a breeding box moving module 40, an agricultural food by-product supply device 50, and a control unit 60. .

The housing 10 has a plurality of chambers 11 arranged along the longitudinal direction and separated from each other. Each chamber 11 may be formed of, for example, a glass material. A chamber fixing frame 12 for detachably fixing the chambers 11 is installed between adjacent chambers 11 . In each chamber 11, a plurality of breeding boxes p containing insects and agricultural food by-products are stacked in several layers (only the lowest breeding box is shown in the drawing). Spaces within the plurality of chambers 11 are separated from each other by side walls of the plurality of breeding boxes p. Each breeding box (p) is designed to allow air to communicate with the outside of the breeding box (p) in a stacked state.

In each chamber fixing frame 12, a separation curtain 14 for separating the chambers 11 is installed (only one is shown in the drawing). The separation curtain 14 is provided with a contact sensor 15 for determining whether or not the top surface of the uppermost layer of the plurality of breeding boxes p is reached. When the separation curtain 14 descends and reaches the top surface of the uppermost layer of the plurality of breeding boxes p, the movement of the separation curtain 14 is stopped. Accordingly, each of the chambers 11 is separated from each other by the side walls of the plurality of breeding boxes p and the separation curtain 14.

The plurality of chambers 11 include an introduction chamber 11a, an exit chamber 11b, and a plurality of growth chambers 11c. The introduction chamber 11a is disposed on one side of the housing 10 in the longitudinal direction and has an entrance door a through which the breeding box p is introduced from the outside. The discharge chamber (11b) is disposed on the other side of the longitudinal direction of the housing (10) and has an exit door (b) for discharging the breeding box (p) to the outside. A plurality of growth chambers 11c are disposed on the moving path of the breeding box p between the introduction chamber 11a and the discharge chamber 11b.
