The following article briefly introduces the operation of the rice huller. Mainly for flow rate, roller pressure, roller hardness and installation, as well as suction shell air volume, the following is a detailed introduction from the Shandong rice huller manufacturer.

1. Traffic

The flow rate mainly affects the hulling rate of the huller, the damage rate of brown rice, the level of gel consumption, and the yield of brown rice. Excessive flow rate leads to an increase in the number and disorderly arrangement of rice grains between the two rollers, resulting in a low chance of rice grains coming into contact with the rubber rollers. Therefore, during husking, the husking rate decreases, the roughness increases, the rubber consumption increases, and the yield may decrease. Low flow rate results in fewer rice grains between the rollers and more opportunities for contact with the rubber rollers. Although it can improve the hulling rate, the yield may decrease and the rubber consumption may increase.

2. Roll pressing

When the online speed difference is constant, the appropriate roller pressure has a higher hulling rate, less damage to the surface of brown rice, lower rough crushing and bursting waist, and less glue consumption, according to the Shandong hulling machine manufacturer; Excessive rolling can cause severe damage to the surface of brown rice, resulting in rough and broken grains and an increase in adhesive consumption; Low roller pressure results in low squeezing force on the rice between the rollers, leading to a decrease in rubbing and tearing force, a decrease in hulling rate, and poor processing efficiency.

3. Roller hardness and installation

Suitable rubber roller hardness, good shelling rate, and low adhesive consumption; Excessive hardness of rubber rollers can easily cause brown rice to break and burst; Low hardness of the rubber roller can cause the surface of brown rice to turn black during hulling, resulting in increased glue consumption. The hardness of rubber rollers is generally Shore 80 90. Generally, fast rollers have a Shore degree 5 higher than slow rollers. For processing japonica rice or in winter, hard rollers with lower hardness should be selected.

4. Suction shell air volume

Appropriate suction air volume can ensure high suction efficiency while reducing the occurrence of grain leakage. Excessive suction air volume can improve the efficiency of absorbing rice husks, but it can also easily cause the grains to be sucked away, resulting in high energy consumption; If the suction air volume is too low, it will cause a decrease in the efficiency of rice husk suction, an increase in the shell content of the grain rough mixture, and affect the grain rough separation effect. Therefore, the corresponding suction shell air volume should be equipped according to different hullers
