The extrusion and puffing process is to place the powdered feed in the conditioner of the extruder, and in a high temperature, high pressure and high humidity environment, the material temperature and pressure continue to rise after being extruded by the spiral extruder. When a certain temperature and pressure are reached, the material is suddenly released from the die hole to normal temperature and pressure, and is cut into products of the required shape and length by a cutter.

[0003] In the prior art, the utility model patent with publication number: CN219308956U discloses an expander for feed processing, which performs primary crushing operation on the feed entering into the crushing box by arranging a rotating motor to drive the opposite rotating gears to drive the opposite crushing rollers, and performs multi-stage crushing processing operation on the feed falling onto the arc-shaped screen plate by arranging a rotating motor to drive the rotating shaft to drive the crushing knife to rotate, thereby further improving the crushing processing effect of the feed, making the feed have a better crushing effect, being able to fully crush the feed with larger particles, and making the crushing of the feed more uniform.
