A rice thresher is a machine that puts grains in and naturally produces rice. In rural areas, many families use egg beaters to beat rice. When the rice thresher is threshing rice, the chaff comes out from the other side, and the chaff is the broken chaff. Bran can be used to feed chickens and domestic pigs.

Key points for operating a rice thresher

Before the brown rice enters the discharge hopper of the rice mill, check if there are any metal objects or stones to avoid damaging the grinding wheel.

After the rice thresher finishes threshing, the front rotating block should be pulled out to clean up the remaining rice sugar in the threshing room to avoid affecting the accuracy of sample loading.

3. The milling accuracy of the rice mill needs to be determined based on the type of brown rice, the quantity of samples and the milling time. The quantity of low-precision samples is 17-18g, and the whitening time is slightly shorter. The quantity of high-precision samples is 20g. The whitening time is a bit longer.

4. When the rice mill has been in use for a long time and is grinding high-moisture brown rice, the rice bran adheres to the grinding wheel, affecting the fineness and whiteness. You can remove the grinding wheel with a wrench and apply a rice bran powder wire brush with a brush. It can be used in its original state.

The operation steps of the rice thresher are as follows:

Before starting work, check whether all parts of the rice mill are firm and whether the pressure rollers are normal.

2. Check if the counter is in good condition and adjust the clamping distance according to the hose specification.

3. Set the counter to zero before hitting the rice.

When feeding the hose into the pressure roller, keep your hand 20 centimeters away from the pressure roller to prevent your hand from being squeezed.

5. If any problem occurs during the rice milling process, the machine should be stopped immediately for resolution. It is strictly prohibited to move the rice during the operation.

6. When handling the hose, ensure it fits well to prevent it from being smashed or crushed.

7. Shutting down: After work is completed, turn off the power and clean up.

Viii. Others: When using a toothless saw, follow the technical operation procedures of the toothless saw.

The principle of a rice thresher

The structure of the grinding type sand roller rice mill consists of a frame and an exhaust fan. The rice milling chamber is fixed on the frame, the feeding device is installed on the upper part of the rice milling chamber, and the rice husk collection hopper is installed on the lower part of the rice milling chamber.

2. The main shaft of the rice milling chamber is a hollow shaft. The air inlets are located at both ends of the hollow shaft. The rice outlet is equipped with a rice cleaning and cooling device. The rice outlet is equipped with an inclined guide plate, and a device for cleaning and cooling the rice is installed at the bottom of the guide plate. The feature of the grinding type sand roller rice mill is that the pressure in the rice milling chamber is relatively low and the linear speed of the rice milling roller is relatively high.

3. As the milling only occurs between the rice roller and the brown rice, as well as between the brown rice and the bran drum, and with the negative pressure bidirectional multi-channel air intake, the rate of broken rice during the rice milling process is low. During the working process, brown rice enters the end of the rice milling chamber from the hopper through the flow regulation mechanism and is pushed into the rice milling chamber by the rotating propeller. When the brown rice fills the rice milling chamber, the advancing spiral is still constantly pushing the brown rice in.

4. The pressure in the rice milling chamber keeps increasing. When the pressure of the brown rice group is large enough to overcome the resistance of the pressure door at the discharge port, open the discharge port and discharge the rice group from the rice milling chamber. Under the effect of grinding, the outer layer gradually peels off to form rice bran, which is discharged through the holes in the bran discharge cylinder, completing the rice milling process. The discharge port is equipped with a cooling and rice-cleaning device to further cool the rice grains.
