Process for producing pet food by utilizing fresh meat grouting technology

Abstract

The invention discloses a process for producing pet food by utilizing a fresh meat grouting technology. The process comprises the following steps: S1, grinding fresh meat, controlling unfreezing temperature and combining a slicing machine, a meat grinder and a colloid mill so as to ensure the fineness of meat pulp from the first step; S2, performing heating and homogenization treatment on the fresh meat pulp, performing pipeline-type circulating self-control heating, and generating strong shearing force in high-speed rotation through a pipeline-type emulsifying pump and precise combination ofa rotor and a stator so as to achieve the purpose of homogenizing and emulsifying the meat pulp; S3, cleaning a meat pulp system by using a CIP online cleaning system so as to solve the technical problems that: in traditional technologies, only pure water is adopted for flushing, incomplete cleaning is likely to be caused, bacterial pollution is caused, and products go bad; and S4, enabling the meat pulp to enter a conditioner for conditioning treatment, and then enabling the meat pulp to enter a double-screw bulking machine so as to complete a bulking process. According to the process disclosed by the invention, the loss rate of proteins and vitamins in the meat raw material in multiple processing processes is reduced by utilizing the fresh meat grouting technology, and the natural freshfragrance of meat, fishes and shrimps is reserved.

Description

technical field [0001] The invention belongs to the technical field of pet feed preparation, and in particular relates to a process for producing pet food by utilizing fresh meat grouting technology. Background technique [0002] In order to achieve the protein level needed for pet growth, traditional pet food is mostly made of "meat powder" raw materials that have been processed at high temperature and then extruded at high temperature again. Repeated high temperatures lead to protein denaturation of meat raw materials, a sharp increase in the loss rate of vitamins, and the natural fresh flavor of fish, shrimp, and meat can hardly be presented. Adding fresh fish, shrimp, and meat to pet food, and then forming products through extruder puffing and granulation, is full of difficulties. Contents of the invention [0003] In order to overcome the technical defects of the protein denaturation of meat raw materials, the sharp increase in the loss rate of vitamins, and the diff...
