[0002] Feed is a general term for food for animals raised by all people. In a narrower sense, general feed mainly refers to the food for animals raised in agriculture or animal husbandry.

[0003] Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, and feed additives. During the production process of feed, the surface of the dried feed usually carries a lot of dust and its own temperature is also relatively high, so it needs to be dusted and cooled before it can be packaged and transported.

[0004] However, a large amount of dust is often generated when pouring and crushing raw materials. Since the feed hopper is connected to the crushing chamber and is fixedly connected, the dust generated when the crushing roller handles the raw materials will spread from the feed hopper to the workshop, and the dust raised when pouring the materials will also spread to the workshop. A large amount of dust is flying in the workshop, resulting in a poor working environment for the workers. Summary of the invention
