Problems solved by technology

The existing rice grading sieve is based on the principle of the difference between broken rice and whole rice, and forms classification when flowing on the plane rotating sieve surface. After continuous sieving with four layers of sieve surface, only whole rice and large rice can be separated. There are four grades of broken rice, medium broken rice, and small broken rice, which cannot clean the bran powder sticky matter produced during rice processing

Abstract

The invention discloses a rice grading and selecting sieve, which is composed of a power mechanism arranged in a frame and a grading and selecting mechanism arranged in a sieve body above the frame. The power mechanism includes a motor in the frame, a speed regulating mechanism, Transmission belt, bridge transmission mechanism, three sets of eccentric rotary mechanism, grading and selection mechanism include sieve grid, flow guide plate, discharge hopper, front sealing plate, feed hopper and receiving hopper in the sieve body. There are five layers of sieve grid. The diversion flow plate is set under each layer of sieve grid, the discharge hopper is set on the lower side of the second to fifth layer of sieve grid and the lower side of the flow guide flow plate, and a discharge port is set next to the first layer of screen to discharge the bran powder in the pipeline. Stickers are screened out. The invention can make the processed rice not mixed with bran powder cohesive matter, and the rice quality is better.

Description

technical field [0001] The invention relates to a rice grading and selecting sieve in the field of rice processing application. Background technique [0002] Grading and selection is an important process in rice processing, and the quality of rice grading will directly affect the quality of the product and the economic benefits of the processing plant. [0003] In the existing rice grading and screening process, it is composed of a power mechanism in the frame and a grading and selection mechanism in the sieve body above the frame; the power mechanism includes a motor in the frame, a speed regulating mechanism, The power mechanism composed of tension mechanism, bridge transmission mechanism and three sets of eccentric rotary mechanism; the sieve grid with sieve holes installed at an inclination angle installed in the sieve body above the frame, the flow guide plate installed at an opposite inclination angle, the matching discharge hopper, The detachable front sealing plate ...
