The principle of small rice milling machine is the movement of rice grains rotating and turning. Rotation is the rotational movement of the short axis orientation of the rice grain, and flip is the rotation of the short axis orientation of the rice grain. In the whole process of rice milling by the rice milling machine, the rice grains must have tumbling motion so that each position of the rice grains can accept the efficacy of the rice milling machine with equal opportunities, so that the rice milling is symmetrical and there are three key points to prevent insufficient rice milling or partial over-milling.

In the whole process of rice milling by the rice milling machine, the rice grains must have tumbling motion so that each position of the rice grains can accept the efficacy of the rice milling machine with equal opportunities, so that the rice milling can be symmetrical, and there are three key points to prevent insufficient rice milling or partial over-milling.
1.rice millRoll-over caused by grinding white roller bars
The speed direction of the rice grains when leaving the tendon and the broken line form an angle of view, so that the rice grains cause more impact frequency and more rolling frequency on a diameter.
2.rice millRice knife, round hole sieve, tumbling caused
The rice grains move at a speed. When they arrive at the rice knife and other places, they bounce back home at the forefront of the rice knife and other places. The different "angles" of the rebound speed and the speed azimuth make the rice grains cause tumbling exercise. Grinding white room rice knife, round hole sieve, more time, rolling frequency is more, on the contrary, less; However, it cannot be increased indefinitely, and it is limited by the factors that affect the structure of the grinding white room and the actual effect of the processing technology.
3.rice millRoll over caused by air spray
Rice milling by wind spraying has been gradually widespread. Under a certain working pressure, the wind is sprayed from the inside of the white roller to the holes or grooves on the surface. The wind force sprayed out generally exceeds the floating rate of rice grains. When the gas enters the white chamber of the rice mill, the volume expands, the working pressure decreases, and the gas mixed flow is generated. The rice grains produce tumbling exercise in the vortex.
Rice milling machine is a machine and equipment for people to process grain and oil. Therefore, we need to maintain it frequently in the whole process of application to increase its service life. So what is the usual maintenance work of rice milling machine?
1、rice millThe production and processing of rice, to maintain a certain dry humidity, the general water content can not exceed 14%-15%. When the water content of rice is too high, the rice grain is crushed, which endangers the quality of rice, and the driving force of consumption is also accompanied by expansion.
2. Pay attention to check whether there are steel nails, stones and other dirt in the rice to prevent blocking or damaging the rice sieve when entering the white grinding room.
3. When starting, run the empty load to all normal speed ratios, then pour the rice into the hopper, and pay attention to the operation status of the rice mill anytime and anywhere.
4. Before starting, check the rice sieve, rice knife, barrel core and other parts to see if the anchor bolts and nuts are tightened.
5. Rotate the barrel before starting to check whether there is a card.
6, after the daily work, to carry out an inspection of the rice mill and service facilities, found that the problem is properly handled, to ensure that the rice mill is often in good condition
