Livestock and poultry bone grinding-tooth-type crushing apparatus and method

Abstract

The invention discloses a livestock and poultry bone grinding-tooth-type crushing apparatus which includes a rack having a hollow structure and arranged in the perpendicular direction; a primary crushing apparatus, which is arranged horizontally along a transversal shaft of the rack in the hollow structure, wherein two ends of the first crushing apparatus are rotatably fixed respectively to the two sides of the rack and are driven to rotate by a driving mechanism; a secondary crushing apparatus, which is arranged horizontally along a transversal shaft of the rack in the hollow structure and is arranged under the primary crushing apparatus, two ends of the secondary crushing apparatus are also rotatably fixed respectively to the two sides of the rack and are driven to rotate by the driving mechanism. The invention also discloses a livestock and poultry bone grinding-tooth-type crushing method with the apparatus. The apparatus and the method solve the problems of poor universality, complex operation and high requirement of land occupation and auxiliary equipment in a conventional crusher, and greatly reduce energy consumption and production cost of crushing bones. The apparatus is simple in operation, is low in maintenance rate and is suitable for crushing various bone raw materials in the type of grinding teeth.

Description

technical field [0001] The invention is suitable for the processing and production of livestock and poultry bones, and in particular relates to a rodent crushing device and method for livestock and poultry bones. Background technique [0002] my country produces about 12 million tons of edible livestock and poultry bones every year, accounting for about 30% of the world's output, equivalent to about 2 million tons of animal protein, which can meet the annual protein demand of 75 million people. Livestock and poultry bones are rich in nutrients such as protein, lipids, and minerals, and have high development value. [0003] When processing livestock and poultry animal bones, the early crushing treatment is very critical. The crushing particle size has a great influence on the processing difficulty and yield of the subsequent process of bone processing. There are several kinds of bone rolling machines commonly used in the past, but they all continue to use other non-food ind...
