Description

Technical Field

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

[0002] With the rapid development of modern animal husbandry, higher and higher requirements are placed on the quality and safety of feed. As an environmentally friendly and efficient form of feed, biological feed has received more and more attention and application. However, the raw materials of biological feed come from a wide range of sources, including various grains, oil crop by-products, etc. These raw materials often contain impurities and unqualified particles, which need to be screened and removed. Screening devices for biological feed have emerged. These devices use advanced mechanical, electronic and automation technologies to achieve efficient and accurate screening of biological feed raw materials. Through reasonable screen configuration and precise control systems, they can remove impurities and unqualified particles from raw materials and improve the purity and quality of feed. The development of screening devices for biological feed is an important manifestation of technological progress in animal husbandry and the feed industry.

[0003] However, the screen of a general screening device is usually fixed on the device, so once the screen is damaged, workers need to remove the screen, which is very troublesome and greatly consumes the screening time of the screening device for biological feed and reduces the screening efficiency. For this reason, we propose a screening device for biological feed. Utility Model Content
