A static screen structure of polishing machine that can effectively reduce the broken rice rate

Abstract

The invention discloses a static screen structure of a polishing machine capable of effectively reducing the rate of broken rice, relates to a polishing machine, and includes a polishing screen surface, the polishing screen surface is a split combination structure, and is buckled and combined to form a hollow column of a polygonal mesh surface Solid structure, between the cylindrical surface is provided with a screen hole working angle of 120 ~ 170 °. The present invention adopts the combined structure of screen surfaces with large working angles, which overcomes the disadvantages of combined screen surfaces with small working angles in the prior art. Due to the excessive rebound impact force of rice grains in the screen, the broken rice rate is too high, and the working angle is increased. And set the arc transition angle in the working angle to reduce the impact force, and increase the number of cylinders at the same time to increase the number of abrasions and make up for the lack of abrasive force; and the hole edge structure of the zigzag sieve hole of the present invention can effectively improve the abrasion resistance. Efficiency, thereby effectively reducing the broken rice rate in the polishing process and improving the rice yield of rice processing. The invention has a simple structure and is easy to manufacture and can effectively reduce the broken rice rate.

Description

technical field [0001] The invention belongs to the technical field of grain processing equipment, and in particular relates to a static screen structure of a polishing machine with simple structure, easy implementation and the ability to effectively reduce the broken rice rate. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for the deep processing and processing quality of grains. They not only require the processed rice grains to be smooth but also more complete, which is not only delicious but also beautiful. The original processing method can meet the integrity requirements, but the production efficiency is too low. The mechanical revolution has affected people's lives and brought about improvements in production efficiency. However, the damage to rice caused by mechanical processing of rice is relatively serious. First, the broken rice rate of rice increases, and the smoothness is affected. In...
