Problems solved by technology

[0002] When the harmless treatment products of livestock and poultry animals have defects such as raw materials and oily outputs are easily corrupted, raw materials, oily outputs, and heavy odors in the production process, and the existing harmless treatment plants for dead livestock and poultry The treatment capacity of the large odor treatment system is solved, which will virtually increase the investment and operating costs of the harmless treatment enterprises. For theoretical and practical research, it is urgent to develop a new process applicable to the industry for the harmlessness, environmental protection, resource utilization, and zero pollution of dead livestock and poultry.

Abstract

The invention provides a flaked meat and bone meal squeezing process which comprises the following steps: step 1, crushing livestock and poultry died of illness and distillers' grains, and pumping the crushed livestock and poultry died of illness and distillers' grains into a melting tank for melting; 2, transferring the materials in the step 1 into a twin-screw extruder through an auger, and transferring solid matters into a squeezer; 3, transferring the oil residue obtained in the step 2 to a three-phase horizontal centrifuge; and 4, transferring the oil residues treated in the step 3 to a presser. The method has the beneficial effects that the operation is simple, the squeezing efficiency is high, the energy consumption is low, the operation requirement on personnel is low, and the problems of high production cost and easiness in decay, mildewing and deterioration of the powder prepared from the livestock and poultry died of diseases are effectively solved.

Description

technical field [0001] The invention relates to the technical field of harmless treatment of sick and dead livestock and poultry, and more particularly to a pressing process for cake-shaped meat and bone meal. Background technique [0002] When the harmless treatment products of dead livestock and poultry have defects such as raw materials and oil-containing products that are prone to spoilage, raw materials, oil-containing products and heavy odors in the production process, and the existing harmless treatment plants for dead livestock and poultry add The large odor treatment system can solve the problem of processing capacity, which virtually increases investment and operating costs for harmless treatment enterprises. Therefore, the industry urgently needs scientific researchers in related fields to systematically analyze the whole process of harmless production of dead livestock and poultry. For theoretical and practical research, it is urgent to develop a new feasible and...
