Pig feed preparation raw material pretreatment process

Abstract

The invention provides a pig feed preparation raw material pretreatment process. According to the pig feed preparation raw material pretreatment process, a pig feed preparation raw material pretreatment processing device is adopted, the pig feed preparation raw material pretreatment processing device comprises a processing shell, a smashing unit and a screening unit, circular sliding grooves are formed in the upper portion of the middle of the inner wall of the processing shell in a bilateral symmetry mode, the smashing unit is slidably arranged in the circular sliding grooves, and the screening unit is arranged on the inner wall below the middle of the processing shell. The problems that when a common feed raw material preparation device is used for processing pig feed, most of feed raw materials are smashed through a double-roller type smashing machine and then granulated, so that raw material powder is prone to adhering to smashing pieces, the smashing pieces need to be cleaned frequently, and unnecessary workloads are increased can be solved; and when feed raw materials are screened, most of the feed raw materials are screened in a vibrating mode, impurities in feed cannot be effectively and completely removed, and therefore it cannot be guaranteed that the processed feed meets the using requirement.

Description

technical field [0001] The invention relates to the technical field of pig feed processing and production, in particular to a raw material pretreatment process for pig feed preparation. Background technique [0002] In the process of raising pigs, pig feed is extremely important; pig feed is usually a feed for raising domestic pigs composed of protein feed, energy feed, roughage, green feed, silage, mineral feed and feed additives. Energy feed includes corn, barley, rice, protein feed includes vegetable and animal protein feed, rapeseed cake in vegetable protein, and mineral feed. These feeds mainly meet the needs of pigs for minerals such as calcium and phosphorus. Feed This type of feed can improve the palatability of pigs, and roughage includes hay and crop straw; the raw materials for the preparation of the feed that are initially selected need to be screened to remove impurities in between, so as to obtain feed preparation materials that meet the requirements.

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the processing and production of pig feed raw materials at present: when the general feed raw material preparation device is processing pig feed, most of them use a pair of roller mills to pulverize the feed raw materials first, and then granulate them, so that The crushed pieces are easy to adhere to the raw material powder, which needs to be cleaned frequently, which increases unnecessary workload; and when screening the feed raw materials, most of them use vibration screening, which cannot effectively remove the impurities in the feed completely , so there is no guarantee that the processed feed meets the requirements for use
