Description

Technical Field

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

[0002] Fish feed is feed for fish, and its main components are protein, fat, vitamins and minerals. Protein is an important nutrient for the survival of fish and shrimp, and is an important component of the body's cells, tissues and organs. Therefore, the use of fish feed is of vital importance. During the production and processing of fish feed, the specifications are large or small, and it needs to be screened by a screening device. The existing screening devices for fish feed production and processing have certain disadvantages when used. Fish feed is screened by vibration, and the fish feed is easily splashed with the vibration, resulting in material waste. In addition, the produced feed contains large pieces of feed that are not completely broken. These pieces of feed are difficult to pass through the screen and accumulate on the screen, which can easily cause blockage. In addition, the feed contains a large amount of water, which is easily attached to the screen due to the high humidity during the screening process. Therefore, we propose a screening device for fish feed production and processing. Utility Model Content
