Grain washer is a device used to clean grains in the production of grain and oil processing. It is a kind of equipment that separates and reduces impurities by making use of differences in the physical properties of grain and impurities.

Grain washers can be divided into two categories according to their separation principles: one is gravity type, which uses the difference in the bulk specificgravity of grain and impurities to separate them; the other is sieving type, which uses the difference in the sieve aperture of the sieve to separate them.

The specific application of the grain washer depends on the type of grain and the level of impurity. If the grain is small, such as rice, millet, and corn, a gravity-type grain washer should be used for cleaning. The specific process is: firstly, the ore is fed into the funnel through the vibration hopper, then it enters the body of the washer, and during the whole process, the mixture of ore and impurities passes through multiple layers of sieves with different mesh sizes, and falls into the respective tanks in accordance with the particle size distribution. Finally, the clean grain is collected.

If the grain has more impurities, the sieving type grain washer can be used. The structure of the sieving type grain washer includes the vibrating unit, the sieving unit, the wind selection unit and the dust removal system. During the process, the grain is fed into the vibrating unit through the vibrating hopper, and the vibrating force generated by the vibrating unit can make the grain and impurities move forward and backward repeatedly, and thus effectively separate the impurities from the grain. After the sieving chamber, the wind selection unit selects the grain and the impurity with different specific gravity, and finally the impurity is discharged out through the dust removal system.

The grain washer has the advantages of simple structure, low power consumption, and environmental protection. It plays an important role in the oil and grain processing industry, and can effectively reduce the energy consumption of the whole production process and enhance the economic benefit.
