Fish feed refers to the feed for fish, which contains various important nutrients. Since the particle size of fish feed is different during production, and it will contain more impurities, the use of screening device can be used to filter the fish feed raw materials. Impurities are cleaned, and fish feed with different particle sizes can be graded so that fish feed with different particle sizes can be fed to different types of fish, which is beneficial to the digestion of fish.

However, the structure of the existing raw material screening device is not perfect and there are still certain defects:

1. When existing raw material screening devices screen fish feed, the fish feed is usually poured from the feed port, and then the raw materials of different particle sizes are separated on the screen plate and moved toward the discharge port. , since the fish feed enters from the same feed port, the position of the fish feed falling on the screen plate is relatively concentrated, making the fish feed more crowded when passing through the screen plate, which is not conducive to the rapid screening of fish feed.

2. Existing raw material screening devices are usually designed with a multi-layer structure, which makes it easier for fish feed to produce debris during screening. When cleaning the secondary structure located inside the device, the structure is closed and the opening process is relatively complicated.
