Abstract

The invention relates to a harmless treatment process for sick and dead livestock and poultry. The harmless treatment process comprises the following steps of (1), disinfecting sick and dead livestockand poultry corpses with disinfectants; (2), transporting the disinfected corpses of the sick and dead livestock and poultry to a crusher for crushing, and crushing the corpses into 5 cm meat pieces;(3), spraying the disinfectants on the surfaces of the meat pieces, and pumping the meat pieces into a rendering pot for rendering; and (4), after separating oil and fat, transferring materials intoa reactor, adding medicines into the reactor, stirring uniformly, standing, discharging the upper layer of clean water into a sewage treatment tank, transferring the lower layer of the materials to afilter press for filter pressing, and drying filter cakes to obtain meat and bone meal. The harmless treatment process for the sick and dead livestock and poultry has the advantages of simple operation, low energy consumption, low production cost, low water content of the meat and bone meal and the like, and the quality of raw sewage water is stable.

Description

technical field [0001] The invention relates to the field of harmless treatment of sick and dead livestock and poultry, in particular to a harmless treatment process of sick and dead livestock and poultry. Background technique [0002] With the rise of the harmless treatment of sick and dead livestock and poultry industry, the high-temperature process for the harmless treatment of livestock and poultry has always been a routine treatment method for the harmless treatment of sick and dead livestock and poultry. However, the high-temperature process produces a large amount of waste water and raw water The defects of unstable water quality, long production cycle and high energy consumption have brought great treatment costs and difficulties to enterprises in the harmless treatment of sick and dead livestock and poultry. need to be resolved. Therefore, experts in different fields such as chemical industry, equipment and animal husbandry conduct research on how to efficiently de...
