Rice polisher is equipped with water-cooling system, which can control the processing temperature and ensure the material has no invariance during processing. Inside of the whole grain milling machine is installed the air classification system. These machines are corrosion resistant and are offered with latest advanced functions.

Rice polishing machine gives superior whiteness to rice and is well suited for raw and single boiled rices. In the complete maintenance of rice polisher machine, we can disassemble the motor and maintain it, clean the motor bearing and infuse oil, check the insulation monitoring, make the cooling system perfect, ensure the motor work in the good condition and so on.The rice polishing machine is equipped with water-cooling system, which can control the processing temperature and ensure the material has no invariance during processing.

About 2.8 kg each from raw paddy rice samples were soaked in plastic containers and covered at a level just above the paddy, drained with sieve and then steamed for about 30 min, during which paddy kernels were split from top to bottom. Paddy rice samples were soaked in hot water at 80°C for 3 h, as used by Ituen and Ukpaka. The steaming (at boiling point) was done for 25-30 min, the samples were taken out and allowed to temper for 3 h (aiming at reducing the moisture content to prevent cracking while drying) as suggested by Dauda. The samples were sun dried for about 3 h, being the rainy season and shade dried for 1-4 days, by spreading paddy thinly on matted bags and stored in airtight bags and plastic containers before dehulling.

Separation of paddy and rice on an oscillating type paddy separator takes place due to difference in specific gravity and surface characteristics of paddy and rice. When a mixture of paddy and rice falls on a separator having a serrated surface and is oscillated at the appropriate frequency, rice settles down under the layer of paddy. If the inclination of deck exceeds the angle of friction between the rice and paddy, the paddy moves down the deck on top of the layer of rice. This angle of inclination exceeds the angle of rolling friction between the paddy and the material of the deck and the paddy after having been separated from the layer of rice rolls down on the deck surface.
