1. Installation of Rice Mill The installation of the rice mill can be based on needs. For machines that do not need to move, it is best to install on the cement base. The size of the base is determined by the size of the rice mill power. High-power rice mill base size can be larger. If the rice mill needs to move often, the rice mill and the power machine can be mounted on the same movable base.
2. Power selection of rice mill The power matching of the rice mill must meet two conditions, one is power; the other is that the speed should meet the requirements. The power is mainly selected according to the calibrated power on the rice mill's nameplate. Its power is generally 1.2 to 2.3 times the power of the rice mill, and it is necessary to match the appropriate pulley to make the rice mill have a suitable rotation speed.
3. Check before using the rice mill Before use, check whether the safety device is safe and reliable, whether the connection part is connected reliably, and whether the bolt is firm. Check if there is any foreign matter in the indoor area and whether the rotation of the roller is flexible or not. Check whether the installation condition of the roller meets the requirements. If it is a rice machine with two rollers, the connecting end of the roller should be flat and the ribs and ribs must be aligned. When the alignment is impossible, the protruding direction of the ribs should follow the flow direction of the rice. • Check the installation of rice sieves. When the two-mesh rice machine splicing laps, it should always follow the flow of rice, and there must be no gap during the connection. The gap between the sieve and the roller should be the same. Check whether the oil and oil content in the bearing cavity and grease cup meet the requirements. If necessary, add or replace the oil. • Check that the direction of the rice-milling machine is correct. If it is confirmed that there is no abnormality in the safety and reliability of the rice-milling machine, it can be tested to idle. If problems are found, it must be resolved in time.
4. Milling machine adjustment Milling times when the rice mill requires a certain pressure, the greater the pressure, the higher the accuracy of whitening, to a white, often due to excessive pressure caused by increased broken rice rate; if the pressure is small , uneven whitening, draining the net is not clean. The best way is to do it in two or three times, whitening, high precision grinding, broken rice, high rate of rice. Roller speed adjustment The roller speed is related to the movement speed and pressure of rice grains in the whitening room, which must affect the productivity and quality of the rice mill. The first time the grind should reduce the speed, increase the pressure; two or three times when the pressure should be small, the speed can be slightly faster. When the moisture content of rice is high or belongs to silty rice, the rotation speed should be slower. Therefore, the roller speed should be adjusted according to the actual situation according to the product specification. Inlet and outlet gate adjustments The opening of the ltyJ board can adjust the flow rate and control the pressure of the whitening chamber, directly affecting the rice mill productivity, grinding accuracy, export rate and power consumption. In actual production, imported shutters are used to control the appropriate flow rate, and the outlet shutter is used to control the pressure of the whitening chamber to meet certain requirements. The size of the knives to adjust the size of the gap between the knives and the mixing drum affects the accuracy of the grinding and the broken rice rate. Therefore, the adjustment of the rice knives should be coordinated with the adjustment of the opening of the inlet and outlet gates. Generally, the entrance gate is opened first, and the outlet gate is used to adjust the accuracy of grinding. If it fails to meet the requirements and then adjust the meter, then check the opening of the inlet gate to see if it can increase the flow. After adjusting to meet the requirements, the fixing nut is tightened and is no longer arbitrarily changed. Rice sieve adjustment If you find that the whole rice grains are mixed in the rice bran, you should check whether the rice sieve has leaked rice. If the meter screen is improperly installed or damaged, it should be reinstalled or repaired, and new parts should be replaced when the damage is severe. If it is not due to improper installation and breakage of the rice screen, replace the smaller screen rice screen.
5. The operation method of the rice mill The pre-processing inspection and inspection requires that the milled rice should be suitable for the degree of wetness, and the grain must not contain iron, stone and other hard objects. The processed rice varieties should be the same or similar. • After the feed inlet and outlet materials are switched on, they can be fed only after they are operating normally. Feeding from less to more, gradually increase to the rated load. According to the requirements of whitening accuracy, the discharge gate should be adjusted until the rice quality meets the requirements. The operation adjustment should pay close attention to the operation of the rice mill and the power machine during the operation. When it is found that there is a change in the accuracy of whitening, it should be adjusted in time to stabilize the quality of the product. If the rice machine or power machine has abnormal noises or other abnormalities, it shall be stopped and checked immediately, and the trouble can be continued until the malfunction is corrected. Abnormal Shutdown In the event of a sudden power outage or other reasons that cause the rice machine to be blocked, the power source should be cut off, and the Panasonic drive belt should be used; slowly turn the rice mill pulley in both positive and negative directions to grind the rice in the white room. Drain to reduce the load at restart. When the rice needs to be stopped during the completion of grinding or work, the feed gate must be closed first to allow all the grains in the white room to be discharged before power is turned off. Safe operation operators should tighten the cuffs, wear masks and work caps, and no part of the body should be close to the belt or pulley to avoid unsafe accidents.
6. Maintenance of Rice Mills Rice knives and rice sieves are easy to damage and should be worn out. After the knife is blunt, the adjustable head can be turned over and it should be replaced when serious. • Always check the firmness of the pulleys and fastening bolts during work. If loose, tighten them in time. Check the bearing lubrication regularly and add or replace the oil regularly. After processing, the rice mill and power machine should be cleaned. When it is not used for a long time, all the materials in the whitening room should be cleared out, and the material entering and exiting the shutter plate should be closed so as to avoid moldy deterioration of the remaining grain in the whitening room. And Panasonic belt, in order to prevent the long-term tension in the belt and deformation.
