Harmless treatment system for dead livestock and method thereof

Abstract

The invention discloses a harmless treatment system for dead livestock and a method thereof. The dead livestock are directly crushed into minced meat or small-sized meat pieces, and extruded by an extruder, and the crushed dead livestock are processed into cooked minced livestock meat. On one hand, bacteria can be killed in the process of high-temperature extrusion, and on the other hand, the crushed livestock minced meat is heated and cured into fermentation raw materials, and in the extrusion process of the extruder, generated waste is led out to a waste treatment device for purification treatment, the air pollution problem and the odor problem of a processing site are avoided, and the sanitary safety of treatment is improved; and the processed cooked livestock minced meat can be transferred to a fermentation bed or a high-temperature dry anaerobic fermentation tank for fermentation treatment, so that finally obtained residue can be prepared as an organic fertilizer raw material, biogas generated by fermentation can be led out as a gas fuel, and the economic utilization value of products in various links of harmless treatment can be realized.

Description

technical field [0001] The invention belongs to the technical field of livestock treatment, in particular to a harmless treatment system and method for sick and dead livestock. Background technique [0002] The existing harmless treatment of sick and dead livestock usually adopts the method of burying and then throwing lime for treatment. This method can to a certain extent inhibit the spread of germs and isolate the dead livestock from rotting, causing further environmental pollution. However, , on the other hand, this has also brought large economic losses and land occupation problems, because the soil used to bury sick and dead livestock will definitely not be able to be used for normal reclamation in the short term, although there have been some cases of dead livestock After the livestock is dismembered, the technical literature of adding fungi to decompose is publicized. However, there are no companies that have implemented specific applications so far. Not only the cos...
