Description

Technical Field

[0001] The utility model relates to the technical field of screening, in particular to a screening device for feed processing. Background Art

[0002] Feed is a general term for food for animals raised by all people. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Nowadays, with the rapid development of the current economy, a variety of foods have appeared on people's tables. For this reason, livestock breeding is a very important link in the current food supply chain. Currently, livestock breeding mostly adopts the method of feeding feed. The feed mainly consists of soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, feed additives and other ingredients. During production, the feed needs to be screened according to the particle size.

[0003] The existing feed screening equipment generally places the screen plate at an angle, and the feed is quickly screened through the screen plate. The feed rolls to a lower position through the height of the screen plate and is screened only once. The screening is insufficient, resulting in a poor screening effect for the feed. The screening effect of the feed is increased by increasing the length of the screen, but the size of the screening equipment is increased, which makes the equipment inconvenient to move and occupies a large space.
