Rice milling chamber structure

The rice milling chamber has a hollow shaft, sand roller, iron roller, rice screen, etc. Hollow shaft, spiral head and main shaft sleeve. The sand roller with ventilation holes is sleeved on the outside of the hollow shaft, the rice screen is sleeved on the outside of the sand roller, and the rice screen strip is fixed on the rice screen. The spiral head is fixed to the feeding end of the hollow shaft, the main shaft sleeve is fixed to the outside of the spiral head, and the spiral head has an air inlet hole 1, the main shaft sleeve has an air inlet hole 2, and air inlet 1 and air inlet 2 are provided at both ends of the hollow shaft, so that a sandwich air inlet channel is formed outside the hollow shaft in the rice milling chamber.
It can be seen that air inlet 1 and air inlet 2 constitute the two-way air inlet of the main shaft, and the air inlet channel becomes a four-channel. The increase in air inlet volume and pressure in the rice milling chamber makes the material in a suspended state, greatly reducing the influence of gravity on the material and improving the rice milling efficiency. The pressure in the rice milling room gradually tends to be consistent with the expansion of the air inlet area. The negative pressure strong ventilation fully reduces the rice temperature, makes the bran discharge more complete, is not easy to be blocked, the screening area is effectively utilized, the breakage rate is reduced, and the output is increased.
