Description

Technical Field

[0001] The utility model relates to the technical field of puffing equipment, in particular to an extrusion screw-type puffing machine. Background Art

[0002] Extrusion puffing is a technology that uses an extruder to make finely crushed materials into puffed particles. The main process is as follows: the material is crushed and put into the extrusion barrel, and the rotating spiral is used to extrude the material to form a high-temperature, high-pressure gelatinized material, which is rapidly expanded and cooled, and then extruded through the extrusion hole, and then cut by a blade to form puffed particles.

[0003] The puffed particles extruded by the puffing machine are usually of a columnar structure, and the particle size of the puffed particles is usually determined by the size of the extrusion hole of the puffing machine and the cutting process of the blade (where the extrusion hole determines the cross-sectional size of the puffed particles, and the cutting process of the blade determines the length of the puffed particles). The particle size of the puffed particles extruded by the puffing machine (especially the cross-sectional size of the puffed particles) is usually difficult to adjust, and during fishing, as the fishing environment changes, the particle size of the required bait also needs to change accordingly. Therefore, the output of the existing puffing machine is difficult to adapt to the changes in the fishing environment, and the configuration of multiple models and types of puffing machines will increase production costs.
