Rice milling plant is a set of five major machines consisting of cleaning, hulling, grain separation, rice milling, and grading. Customers can add polishing, color sorting, packaging scales and other three parts according to the needs of the test machine. The machine can complete the continuous operation from husking the clean grain to grinding into white rice, and at the same time discharge the chaff out of the machine, and the fine bran is collected by the dust collector. , less power consumption, easy operation and maintenance.
The determination of the inclination of the screen surface is generally between 10 and 13° according to the size of the test screen surface inclination. If the inclination is too large, the resistance to the upward movement of the stone will be large, and the speed of entering the selection room will be slow, or even difficult. At the same time, due to the accelerated flow rate of the grains on the screen surface, the stones may be washed away by the grains. If the inclination is too small, although the resistance of the upward movement is small and it is easy to be discharged, the movement speed of the grains on the screen surface is too slow, which affects the output, and the grain content in the equipment will increase accordingly, so the inclination of the screen surface should be keep it appropriate.
Adjustment of air volume, under certain other conditions, the air volume of rice milled noodles can be judged according to the movement state of the material on the screen and the quality of the two products. When the air volume is too large, the material on the screen will not only float, but also There will even be blow-through, turning bubbles, etc., which not only destroys the automatic classification, but also blows up some flake mud from the bottom of the material layer and discharges it from the mouth along with the rice. In this case, the small damper must be closed or Reduce fan speed.
Control of the flow rate, if the flow rate of rice milled noodles is too large or too small, the stone removal efficiency will be reduced. The surface is seriously unevenly distributed, resulting in unclear separation. The flow rate is too large, the grain layer is thick, and the stones and grains cannot be fully graded, which will also reduce the effect of the equipment. Therefore, the control of the flow rate should be adapted to the rated output of the equipment and the characteristics of the sand and gravel contained in the raw grain.
The working screen surface should be flat, and there should be no unevenness. Before starting the machine, check whether each bearing seat is tightened, whether other important connecting screws are tightened, and the screen surface should be covered with a layer of material in advance, so as to avoid uneven airflow distribution due to the fact that the material cannot cover the screen surface in time when starting the machine. From time to time, it is necessary to frequently check the situation of stones and grains in the net grains, and find out the reasons in time to take corrective measures.
For rice processing manufacturers, safety is always the primary issue. Manufacturers of rice processing plant should manufacture high-quality equipment to ensure the safety of rice processing manufacturers in use and operation, and to reassure the processing manufacturers. At the same time, it is also required to improve the service life of rice milled lines, and the operation and maintenance are simple and convenient. Minimize the maintenance time of rice milled lines as much as possible, reduce the long-term operating costs of manufacturers, and do a good job in after-sales service.
