Processing method for livestock and poultry died of illness

Abstract

The invention discloses a processing method for livestock and poultry died of illness. The processing method comprises the following steps that livestock and poultry died of illness are disintegrated through a disintegrator; disintegrated dead bodies are loaded into an disintegrated material receiving device; the disintegrated dead bodies are put into a drying chamber and subjected to direct sterilization drying through hot gas with the temperature being 120-320 DEG C, and grease flowing out in the sterilization drying process is collected and utilized; meat, hairs, bones and other substances subjected to sterilization drying are subjected to squeezing processing; the grease and surplus materials are obtained after squeezing processing, and after being smashed, the obtained surplus materials are added with a mixture to be made into raising raw materials; 100 mass parts of the raising raw materials are added with 0.5-1 mass part of EM original liquor, the raising raw materials and the EM original liquor are mixed and then ferment for 3-5 days, and raising materials with the water content being 55 wt%-70 wt% is prepared; black soldier flies are inoculated in the raising materials, and the raising materials are used for supplying food to black soldier fly larvae; after the raising materials are converted into small-granular residues, the larvae and the residues are separated, and the black soldier fly bodies and the surplus residues are obtained; and the surplus residues are used for making organic fertilizers.

Description

technical field [0001] The invention relates to the technical field of resources and environmental protection, in particular to a method for treating sick and dead livestock and poultry. Background technique [0002] Harmless disposal of sick and dead animals is an important measure to prevent the spread of animal diseases, effectively control and exterminate animal diseases, and prevent pathogens from polluting the environment. Since the 1980s, due to the frequent occurrence of major animal diseases such as foot-and-mouth disease, mad cow disease, and highly pathogenic avian influenza, society has paid more and more attention to the harmless disposal of animal carcasses. my country is a big country in poultry and livestock breeding, and its breeding scale ranks among the top in the world. During the breeding process of poultry and livestock, there is a certain mortality rate due to weather, epidemic diseases and other reasons. For dead poultry and livestock, it is necessar...

AI Technical Summary

Problems solved by technology

[0005] The traditional method can solve the environmental pollution caused by diseased poultry and livestock flowing into the market, and realize partial resource utilization of sick and dead livestock and poultry. However, the investment and treatment costs of harmless treatment are still high, and the value of resource utilization is not high. During the fermentation process will produce secondary pollution

At present, most enterprises dealing with diseased poultry and livestock need to rely on policy subsidies to operate. To fundamentally solve the problem of diseased poultry and livestock entering the market, it is still necessary to solve technical problems such as the high cost of harmless treatment.
