Description

Apparatus for separating musca domestica larvae and system for processing food-waste using the same}

The present invention relates to a housefly larvae separation apparatus and a food waste treatment system using the same, and more particularly, to decompose food waste and obtain organic fertilizer, larvae feed and pupa feed in a semi-automatic system considering the ecological characteristics of housefly. It is about the system.

Recently, many efforts and attempts have been made to effectively treat and recycle food waste. In general, there is a method of using food waste as an animal feed, but it requires complicated processes and devices such as selecting foreign substances from food waste, adding various auxiliary feeds, and going through processes such as sterilization and fermentation. It has a disadvantage. In addition, the animal feed thus prepared has been limited in its use due to the danger of mad cow disease in recent years, so the throughput of food waste does not increase significantly.

On the other hand, biological methods that use enzymes, bacteria, earthworms, fly larvae (egg maggots) to treat food waste are environmentally friendly, enable more complete sanitary treatment, and additionally feed or compost such as food and compost. It is attracting attention because it can be recycled and used. However, the method using the microorganisms such as enzymes, bacteria, etc. has a drawback that it takes a lot of time, the method using the earthworm is the most common among them, but because of the degrading capacity of waste, it takes a lot of time, breeding earthworms It is difficult to collect the earthworms for the surroundings, and there are many problems such as the need to add a separate additive to the waste so that the earthworms can inhabit.

On the other hand, the use of fly larvae can shorten the processing time of food waste, but because it is difficult to breed large numbers of fly larvae, there was a problem that it is difficult to apply to waste disposal.

Korean Patent Application No. 99-14619 discloses an automatic waste treatment system using fly larvae, but since it does not take into account the ecological characteristics of the housefly, the spawning rate and hatching rate are very low. Since the decomposition rate of the waste is very low without consideration, there is a problem that it is difficult to substantially achieve the object of the invention. In addition, in the food waste treatment system using fly larvae, it is essential to separate the larvae in a live state because some of the fly larvae must be collected and reused as adults in the post-treatment step of the decomposed food waste. However, since it is very difficult to isolate the larvae in a live state as well as after sterile heating treatment, the object of the present invention cannot be substantially achieved without overcoming these problems. In addition, Korean Patent Application No. 98-042403 discloses an automatic device for inoculation and hatching of fertilizer for livestock meal, but still has the same problem as above.

Since the waste treatment method or system using the housefly is a biological one, it is essential to consider its ecological characteristics. Although the methods proposed in the prior art are composed of automatic systems, the spawning rate, hatching rate and survival rate of larvae There was a difficulty in achieving the desired purpose because it was so low that food waste could not be completely disassembled.

Accordingly, an object of the present invention is to provide a separation device for breeding fly larvae using food waste and efficiently separating the degradation products and larvae to minimize the loss of the reared larvae so that some of them can be reused as adults. It is.

Another object of the present invention is to solve the problems of the prior art by using a semi-automatic system in consideration of the ecological characteristics of the housefly, improve the decomposition rate of food waste food waste treatment system that can be directly used as organic fertilizer decomposition products To provide.

Sugar and whole milk powder were used as food for fly flies, and sugar was supplied to one part of the feeder 7 and whole milk powder was separately supplied to the other part. Breeding was 28 ± 1 ℃, 65% RH, 16: 8 LD conditions, the water for adult growth was supplied to the water supplying sponge (8) by the automatic water supply device (70) in 500ml intervals every 6 hours. .

The food waste used in the present invention may use food waste itself, but is preferably a food waste transfer material processed therefrom. The food waste transfer material refers to a food waste fermented, solids, synthetic resins, etc. are removed and evenly crushed, and then dried and mixed with busy or lime for desalination. Such food waste pretreatment devices or methods are well known and commercially available and will be apparent to those skilled in the art. Therefore, the food waste treatment system according to the present invention may further include the above food waste pretreatment device, and may purchase and use food waste transfer material on the market.

In the above, the medium provided in the egg sheller 6 is a mixture of food waste transfer material and water, so that the fly adults scatter only the egg sheller 6. In this case, since the amount of scattering varies depending on the mixing ratio of moisture to the amount of food waste transfer material, it is shown in Table 1 by measuring the amount of scattering while varying the moisture.

Scattering amount according to moisture content Hydrogen amount (ml) --------------------------------------------- ---------- 0 25 50 75 100 Scattering Amount (g) 0 0.06 1.5 3 3
