Technical Field

[0001] The utility model belongs to the technical field of feed puffing, and specifically refers to an extruding device for fish feed processing with a preheating function. Background Technique

[0002] Puffing processing is a new technology for feed processing that has developed in the past decade. Feed puffing is to extrude feed with an extruder, which expands, loosens, and cooks the raw materials under the action of high temperature and high pressure, and kills the germs and insects in them, making the feed easier to digest and more hygienic, which is beneficial to the health of animals.
