The working principle of the new millet rice mill in Linyi: Millet is manually or screw transported into the hopper of the rice mill, controlled by a gate, enters the rice milling chamber, and is propelled by a screw propeller in the rice milling chamber. Under the joint action of the iron drum, semicircle, and rice sieve frame, the outer skin of the rice is ground off. At the same time of rice milling, the high-pressure air of the jet fan passes through the main shaft aperture and is blown into the rice milling chamber. The bran powder is blown through the rice sieve and enters the crushing system to be crushed into fine bran. Then, the air is sent to the bran storage bag, and the milled rice enters the polished rice polishing chamber. The polishing accuracy is adjusted by the pressure valve at the rice outlet, and the cleanliness of the rice is controlled by the air volume adjustment handle on the right side of the rice hopper If the air volume is too strong, the rice grains will be sucked into the bran. If the wind is too weak, the finished rice will contain bran. When using, adjust it appropriately according to the actual situation to separate the bran and rice.
