Description

Technical Field

[0001] This utility model relates to the technical field of food processing, and in particular to a snowflake powder particle grading sieve device. Background Technology

[0002] Snowflake powder is a type of fishing bait, named for its snowflake-like shape and texture. It has a low specific gravity and good atomization effect, and is usually used as a supplementary bait.

[0003] Existing snowflake powder particle grading and screening devices, such as the particle grading and screening device disclosed in utility model patent application number 202421995749.X, mainly include a frame and a shaking frame. The shaking frame is slidably connected to the frame, and a vibration mechanism for controlling the forward and backward movement of the shaking frame is provided in the frame. In use, the frames are stacked vertically, which is convenient for workers to disassemble and assemble. When the screening frames are stacked, the thermoplastic elastomers that have been screened can be pushed out, which is convenient for workers to remove and take away the screening frames after the subsequent screening work is completed.

[0004] However, most existing grading screens rely on vibration to enhance the screening effect, which is noisy. The equipment is easily damaged by long-term vibration, and the screen is easily clogged after long-term screening, affecting the screening efficiency. Utility Model Content
