The working principle of rice rolling machine rolling rice

The principle of rice milling is very simple, it is by extrusion and friction. A cast iron cylinder, divided into upper and lower parts, the lower part is fixed on the pedestal, there is a rice outlet underneath.

The upper part has a rice inlet that can be opened to clean the inside. There are bearing frames on both sides of the cylinder, fixing an intermediate iron shaft, with a small gap between the shaft and the cylinder, and the intermediate shaft has six winding thumb-thick knife strip axes, with the angle of winding getting smaller and smaller, and there is a pulley on one side of the intermediate shaft, which is driven by a diesel engine.

The rice is poured into the rice inlet (there is a big funnel on it, which can put a lot of rice), the rice is extruded into the cylinder by its own weight and rotation, and the extrusion pressure is getting bigger and bigger, and the paddy is extruded and rubbed so that the bran is refuted, and the bran and the hulled rice fall out from the rice outlet together.

Expanded information

Note:

1, brown rice into the hopper, should be checked for metal objects and stones, so as not to damage the grinding wheel.

2, milling white finished should be pulled out in front of the rotating block, the residual milling chamber of the rice sugar to clean up, so as not to affect the accuracy of the specimen.

3, milling accuracy needs to be determined by the variety of brown rice to determine the number of specimens and milling time, low precision specimen number of 17-18g appropriate, milling time is slightly shorter; high-precision specimen number of 20g appropriate, milling time is slightly longer.

4, when the machine is used for a long time and milled high water brown rice, rice bran bonding wheel affects the fine white degree, can be used to remove the wheel, with a wire brush to remove the chaff powder, according to the original sample can be loaded back to continue to use.
