Description

Technical Field

[0001] The utility model mainly relates to the field of feed additives, and in particular to a feed additive screening device. Background Art

[0002] Feed additives refer to small or trace substances added during the production, processing and use of feed. They are used in small amounts in feed but have significant effects. Feed additives are raw materials that must be used in the modern feed industry. They have obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of livestock products. Feed additives mainly include: bile acid, acidifier, calcium formate, sodium diacetate, trace elements, vitamins and amino acids, etc.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] Before adding powdered feed additives to feed, the feed additives need to be screened through a screening device to screen out large particles to prevent large particles of the additive from entering the feed and being unable to mix with the feed. However, during the screening process, large particles of the additive will remain in the screening device, and the screening device needs to be stopped periodically to take out the large particles of the additive, resulting in a decrease in the screening efficiency of the screening device for the feed additive.

[0005] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content
