White Rice Grading Screen
Category：
Four suspenders are connected to the frame and the structure adopts an inertial transmission mechanism without eccentricity. This machine adopts self-developed technological achievements and increases the screening area through a unique screen configuration, greatly improving the grading accuracy of rice. Its processing property and mechanical property have reached the domestic advanced level. This machine uses the differences in grain shape between broken rice and whole rice grains to execute overlapping slewing and friction advancement on the surface of the gyratory vibrating screen for automatic grading. After the material passes through the feeding and mixing devices (meanwhile, the rice bran is sucked away through the duct and the rice temperature is lowered), then, enters the screen body. Through the unique screen surface configuration and at appropriate rotating speeds, four grades of rice are selected: special rice, ordinary rice, big broken and small broken rice.

The gravity paddy separator separates the brown rice from the husked rice mixture by utilizing different physical parameters such as specific gravity, friction coefficient and particle size of the brown rice and paddy in the husked rice mixture. The paddy mixture produces relative motion between materials under the sine movement of the separating plate, eventually layering the mixture. As a result, the brown rice with high specific gravity and small particle size occupies the lower space and pushed upward by the convex tip of the separator plate. At the same time, the brown rice gradually moves toward the brown-rice outlet due to the longitudinal tilt of the separating plate. On the contrary, the paddy with small specific gravity and large particle size slides towards the bottom direction of the separating plate relative to the brown rice; meanwhile, the paddy gradually slides towards the grain outlet subjected to the longitudinal tilt of the separating plate.
