When the sample (brown rice) ground into the whitening chamber from the hopper into the drive, due to the pressure of thallium internal pressure and mechanical force, the brown rice extrusion in the whitening chamber, through self friction, and between brown rice and grinding against each other, which can quickly remove the brown rice to cortex, measured by grade the whitening degree in the regulation of a certain period of time.

Our small milling machine there are three main types: separation type rice mill, combined rice milling machine and air jet milling machine.

Separation type rice milling machine is easy to operate, the price is low, but the aging model of the milled rice quality is poor, has been gradually phased out.

Combined rice milling machine, machining quality is good, but its structure is complicated and expensive.

Spray type rice milling machine, has a good price performance, can be completed once the shelling, grinding white procedures, processed finished rice white bright, in recent years has become the mainstream market products.
