Description

Treatment of slaughter waste and method of rearing larvae in Dongae, etc.{METHOD FOR TREATING SLAUGHTER WASTE AND BREEDING BSF LARVA}

The present invention relates to a method for treating slaughter waste and rearing larvae in Dongae, and more particularly, to a method for mass-proliferating larvae in Dongae, etc., while treating slaughter waste including blood and intestines using larvae in Dongae, etc. About.

In general, meat such as beef, pork, and chicken, which we eat a lot in our diet, is slaughtered in a slaughterhouse and distributed only for food to be eaten by ordinary consumers. , Slaughter wastes (by-products) containing internal organs and blood are produced.

These slaughter wastes (by-products) have been solved by incineration or landfilling and dumping in the ocean, but in recent years, due to environmental pollution problems, treatment of the above method has become increasingly impossible.

In order to solve this problem, in recent years, various treatment devices have been developed to recycle as feed or compost (manure) using slaughter waste. As an example, Korean Patent Registration No. 10-175311 discloses a slaughter waste removal apparatus for removing moisture contained in internal organs using a screw shaft. Such a slaughter waste treatment device removes moisture so that slaughter waste does not spoil, and then processes it so that it can be used as feed or compost. However, even if slaughter waste is processed, it should not be fed to ruminants such as cattle, even if it is fed as food for its own livestock. Also, blood in slaughter waste was difficult to use as feed or compost because of its perishables.

In recent years, attempts have been made to treat organic wastes such as food using larvae in Dongae and the like. In Dongae, the period from egg to adult is 37-41 days, and the period of larvae acting as a decomposer is about 14 days. Dongae and other larvae have a habit of crawling out to find a dry place to become a pupa after a period of time (about 14 days) to decompose organic waste. If 5000 caterpillars are added to Dongae etc. to 10kg of food waste, more than 80% of the food waste is decomposed in 5 days, and the volume of the decomposed food waste is about 42% and the weight is reduced to about 70% compared to before the larvae were added.

However, until now, Dongae, etc., have been applied to food waste discharged from homes, organic wastes generated in industrial sites, human meals from livestock sheds, etc., and there has been no example applied to slaughterable wastes containing a large number of blood.

The present invention is to provide a method for treating slaughter wastes including blood and intestines using larvae in Dongae et al., and at the same time proliferating larvae on Dongae et al.

The present invention is to provide a method for removing odors generated in the process of rearing larvae in Dongae.

One aspect of the present invention

Providing larvae to slaughter wastes including blood and intestines, moisture regulators, and dongae in a larva breeding ground with a rearing space provided therein; And

It relates to a method of rearing larvae in slaughter waste treatment and larvae including the step of growing larvae by maintaining the temperature of the larvae at 27±3°C and humidity at 60±20%.

In the method of treating slaughter waste and rearing larvae in Dongae, etc. of the present invention, the moisture content of the slaughter waste is controlled and fed so that water contained in a large amount of blood and intestines can be easily ingested by Dongae, etc. using a moisture control agent. Accordingly, the method of the present invention shows that most of the slaughter waste including blood can be treated using Dongae et al., and this slaughter waste can be feed for larvae in Dongae et al.

It can be seen that the fecal soil generated after breeding in Dongae, etc. of the present invention contains phosphoric acid, gari, magnesium, alkali powder, etc. in addition to the constituent nitrogen, and thus can be used as compost through the process of maturation.

That is, organic additives can increase the growth rate by supplying carbohydrates, fats, vitamins, or inorganic substances to the larvae to Dongae. Depending on the type and ratio of useful organic additives, the weight of the larva can be increased by 5% to 20% or more.

In the present invention, the larva can be reared by maintaining the temperature of the larvae at 27±3°C and the humidity at 60±20%.

Each 550g was added. Was paid extra. ⑤ When fecal soil accumulates over 3cm, the fecal soil was removed to improve feeding efficiency. ⑥26~27℃, feeding efficiency in an environment of 60~80% humidity, growth period until homeless larvae and 500g of pupalized larvae after fasting for 3 days were randomly collected, and the average weight of 300 animals per group was repeated 3 times, and fecal soil was placed in a box to measure the volume. And compared. Table 1 below (Group A: 42.3kg (average of two repeated experiments)) and Table 2 (Group B: 47.9kg (average of two repeated experiments)) are tables summarizing the experimental conditions of groups A and B.

Table 4 below shows the average weight (average weight of 300 animals per group 3 repetitions) of larvae in Dongae, etc. bred in Examples.

A weight (kg) B weight (kg) 45.0 47.4

Referring to Tables 3 and 4, it was confirmed that the weights of fecal soil and larvae were not significantly different from those in which food waste was added even under A condition in which no separate food waste was provided. That is, Tables 3 and 4 show that slaughter waste consisting of blood and intestines can be treated as larvae in Dongae, etc., and also show that such slaughter waste can be feed for larvae in Dongae, etc.

In addition, in the case of group B, the weight of fecal soil and larvae increased by 5% compared to the case of group A. This showed that the addition of food waste (additives) can increase the growth rate in Dongae, etc. by supplementing insufficient nutrients in slaughter waste.

3 is a report on the composition of fecal soil generated in Group A of Example 1. Referring to FIG. 3, it can be seen that in Example 1, Group A contains phosphoric acid, gari, magnesium, alkali powder, etc. in addition to the constituent nitrogen, and thus can be used as compost through a process of composting.
