The working principle and daily maintenance of small rice milling machine
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 can be symmetrical, and there are three key points to prevent insufficient rice milling or partial over-milling.

Inrice millIn the whole process of rice milling, 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 or partial over-milling of rice.
1.rice millThe speed direction and broken line of rolling rice grains caused by grinding white roller ribs form an angle of view when they leave the ribs, so that the impact frequency of rice grains on a diameter is more, and the rolling frequency is more.
2.rice millThe rice knife, the round hole sieve and the tumbling rice grains move at a speed. When they reach the rice knife and the like, they bounce back home at the forefront of the rice knife and the like. The different "angles" make the rice grains cause the 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 millThe rolling and rolling of rice caused 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 and the working pressure decreases, resulting in gas mixing, and the rice grains produce tumbling motion 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 produced and processed by rice milling machine shall maintain a certain dry humidity, and the general water content shall 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 to solve the rice sieve, rice knife, barrel core and other parts to carry out inspection, see if the anchor bolts, nuts are tight
5. Rotate the barrel before starting to check whether there is a card.
6, after the daily work, rightrice millAnd service facilities to carry out an inspection, found that the problem is properly handled, to ensure thatrice millOften in an intact condition
