Dry high-temperature harmless treatment process for livestock and poultry died of diseases

Abstract

The invention discloses a dry high-temperature harmless treatment process for livestock and poultry died of diseases. The process comprises the following steps: (1) disinfecting carcasses of livestock and poultry died of diseases with a disinfection liquid; (2) conveying the disinfected carcasses of livestock and poultry died of diseases to a pulverizer for cutting and crushing into particles with particle sizes no more than 5 mm; (3) adding the particles into a mixer, adding accessory materials and carrying out uniform mixing under stirring so as to obtain a mixture; and (4) conveying the mixture to an extruder and carrying out dry extrusion so as to allow water content of the mixture to be no more than 10%. According to the invention, dry high temperature extrusion is employed, so disinfection, sterilization, dehydration and degreasing of livestock and poultry died of diseases can be effectively realized; moreover, the carcasses of livestock and poultry died of diseases are cut to a particle size of no more than 5 mm, so the obtained mixture can be subsequently recycled, e.g., different fertilizers can be prepared from the obtained mixture.

Description

technical field [0001] The invention relates to a dry high-temperature harmless treatment process for sick and dead livestock and poultry. Background technique [0002] With the rapid development of the breeding industry, the death of livestock and poultry will inevitably occur during the breeding process, especially when a major epidemic occurs. Existing methods are mainly the methods such as corpse pond dissolving, cooking method, incineration, deep burial. The corpse method cannot completely solve the spread of germs, and the corpse method itself will also pollute the environment. The cooking method also cannot solve the secondary pollution, and the investment is large and the income is low. Similarly, incineration will also cause air pollution, and deep burial will not only consume a lot of land and manpower, waste precious land resources, but also cause pollution of soil and water resources. Contents of the invention [0003] Aiming at the deficiencies of the prio...
