Abstract

The invention relates to the technical field of food production and manufacturing, and discloses an extruder extrusion mechanism for reducing the damage rate of a screw. The inner cylinder, the position of the outer middle of the inner cylinder is fixedly sleeved with a gear, the gear meshes with the transmission gear I, the transmission gear I meshes with the transmission gear II, and the transmission gear II is movably sleeved on the outer side of the sliding rod , the left end of the sliding rod is fixedly installed with a magnetic piece I. Through the arrangement of the inner cylinder, the material will rub against the thread of the inner cylinder during the process of pushing and extruding the material by the screw. Compared with the flat inner wall of the original device, the device makes the material suffer from the friction during the moving process. The increase of the friction force increases the temperature of the material, thereby evaporating the water, and increasing the air pressure in the cavity, thereby increasing the puffing degree of the material when it is discharged and improving the puffing effect of the material.

Description

technical field [0001] The invention relates to the technical field of food production and manufacture, in particular to an extruder extrusion mechanism for reducing screw damage rate. Background technique [0002] Puffed food is a kind of food that is made of grains and other raw materials by the puffing process with a significantly increased volume. Its main feature is that it has a good taste and is helpful for digestion. The existing puffed food is usually produced by an extruder. [0003] The existing extruder feeds the raw materials into the screw extrusion cavity during operation, and then conveys and extrudes through the screw, and in this process, the material and the material, and the material and the inner wall of the cavity are sheared, kneaded and rubbed. , make the material heat up rapidly, and then gelatinize, and finally extrude the gelatinized material from the discharge port, so that the extruded material is rapidly reduced in pressure, and the moisture in ...
