Bulking machine extrusion mechanism capable of reducing damage rate of screw

Abstract

The invention relates to the technical field of food production and manufacturing, and discloses a bulking machine extrusion mechanism capable of reducing the damage rate of a screw. The bulking machine extrusion mechanism comprises a cavity, the screw is slidably installed in an inner cavity of the cavity, the outer side of the screw is movably sleeved with an inner cylinder, the middle position of the outer side of the inner cylinder is fixedly sleeved with a gear, the gear is engaged with a transmission gear I, the transmission gear I is meshed with a transmission gear II, the transmission gear II is movably connected to the outer side of a sliding rod in a sleeving mode, and a magnetic part I is fixedly installed at the left end of the sliding rod. Through the arrangement of the inner cylinder, materials can rub with threads of the inner cylinder in the process of pushing and extruding the materials by the screw, and compared with a flat inner wall of an original device, the friction force borne by the materials in the moving process is increased, so that the temperature of the materials is increased, water is evaporated, the air pressure in a cavity is increased, therefore, the puffing degree of the materials during discharging is increased, and the puffing effect of the materials is improved.

Description

Technical field [0001] The present invention relates to the field of food production and manufacturing, in particular a puffer extrusion mechanism that reduces screw damage ratio. Background technique [0002] The puffed food is a food product that is significantly increased by a puffed process. It is a main feature that it is good to help digestion, and existing puffed foods usually use a swivel machine. [0003] The existing expansion machine feeds the raw material into the screw extrusion chamber during operation, and then cuts the material from the material, the material and the inner wall of the body, and rubbing the material to the inner wall of the cavity in this process. , The material is sharply warmed, and then gelatinized, and finally the plated material is extruded from the discharge port, so that the extruded material is thrown, where the moisture is rapidly turned to steam, so that the material volume is rapidly expanded, and the puffed Process, but existing expansi...
