How to Properly Maintain The Rice Milling Machine?

Carefully and practically do well in the maintenance of the rice better, so that you can maintain in good working attitude,

You must first maintain below four things:
That is, the surface of the roller used in the rice mill plant should be level, the rice knife or sieving bar should be vertical without gaps, the rice sieve connector should be flush, the screw booster should be flush with the roller, and the roller and roller connector should be a flush direction.

Secondly, the roller rolling equipment should be kept in common with the spindle bearing to do a good job of balancing and dynamic balance of the rotor. When the assembly rice mill plant is sprayed with rheumatism rollers, the rheumatism spray groove and the rheumatism spray hole on the spindle bearing must be pointed to prevent displacement.

After the spiral booster and the protruding rib of the feed iron roller are damaged, they should be replaced immediately.

The rice sieve is usually applied after one work shift, and it should be replaced around or up and down.

Rice knives and sieve bars are usually used for one work shift and should be turned around or replaced left and right.

The input of the rice knife can be slightly larger when it is close to the whitening chamber, and the entrance and exit are slightly smaller. "Inverted drag" is forbidden, that is, the entrance is small, and the entrance and exit are slightly larger.

Again, the adjustment parts such as the working pressure gate of the rice outlet, the steam control valve of the feed, the adjustment screw for the victory or defeat of the rice knife, and the adjustment organization of the gas should be kept flexible.

The rice screen is kept intact during the feeding. After each shift, the congestion on the screen must be cleaned to maintain smooth feeding.

Finally, often check the belt tension, such as in the air-jet rice machine, or double-roll rice machine, you should pay attention to the upper chamber main shaft bearing pushing the lower chamber main shaft bearing, or pushing the air-jet centrifugal fan main shaft bearing belt tension.

The spindle-bearing speed ratio does not need to be changed casually. If it is necessary to change, it should be approved by the production process unit, and it should be noted that the centrifugal fan speed ratio remains unchanged to prevent the actual effect of rheumatism from being harmed.

Check the chaff suction status anytime and anywhere. The centrifugal fan and the ventilation duct for sucking and transporting the chaff are checked once a month at least to eliminate the chaff accumulation.

Import and export trade shaft sleeves should be replaced when they are about to wear out.

You should also pay attention to cleaning the rolling bearings on time and filling them with lubricating grease. Rice knives and rice sieves are easily damaged, so pay attention to the damage. After the rice knife is blunt, it can be turned around and used. If the damage is serious, it must be replaced. Check the tightening level of the belt pulley and the anchor bolts frequently during work, and tighten them immediately if they are loose. 

Regularly maintain the lubrication status of rolling bearings, and add or remove grease on time.
After production and processing, rice mill plants such as rice beaters and power machines should be cleaned and tidied.

When it is not needed for a long time, all the raw materials in the whitening room should be cleaned up, the inlet and outlet gates should be closed to prevent the remaining grains in the whitening room from becoming mildewed, and the transmission belt should be loosened to prevent the transmission belt from being stretched for a long time. The situation changes.

Common problems are to improve the quality of the rice mill machinery, reduce the rate of broken rice, and ensure the normal operation of the rice beater. 

Pay attention to the following matters: 
a. The water content of rice should be ≤15%. When the water content of rice is too high, millet grains The crushing is large, which endangers the quality of rice, and the driving force consumption increases accordingly.

b. Pay attention to check whether there are nails, stones, and other dirt in the rice to prevent them from entering the whitening room to block or destroy the rice sieve.

c. Before starting, check the parts such as the rice sieve, rice knife, drum core, etc., and tighten related anchor bolts and nuts.

d. Rotate the drum before starting to check if there is a stuck condition.

e. When starting, first run the empty load to all normal speed ratios, and then pour the rice into the feeding hopper, and pay attention to the running status of the rice beater anytime and anywhere.

f. After the daily work, inspect the rice beater and service facilities, find that the problem is handled properly, and ensure that the rice beater is in good condition.
