AI Technical Summary

Technical Problem

Existing high-oleic peanut screening devices are not convenient for quickly screening out debris from peanut kernels, and the screen plates are inconvenient to replace.

Method used

A screening device for high oleic peanuts, including a shaking screening component, was designed. The device uses a power motor to drive the transmission shaft and cam to drive the lifting rod, thereby realizing the up-and-down reciprocating motion of the screening box. Combined with the screening box and screening plate made of 304 stainless steel, it has the functions of rapid screening and convenient replacement of the screening plate.

Benefits of technology

It achieves efficient separation of debris from peanut kernels and facilitates the disassembly and replacement of the sieve plate, thereby improving screening efficiency and the practicality of the device.
