The design concept of the rice whitener from ricepolisher's blog

The design concept of the rice whitener is the result of the accumulation of many years of vertical milling engineering expertise. This machine has incorporated all of the most modern techniques of vertical milling and has been proven to be "The Machine" in many major mills throughout the United States and Europe, and in Asian countries such as Thailand and India. The versatility for milling all degrees of milled rice has given the industry the ideal machine.

Two important qualitative indices, degree of milling and percentage of broken kernels, were considered as input variables and the level of pressure on the discharge section of the whitening machine was selected as the output variable in the fuzzy inference unit. Results of the evaluations indicated that the developed ACS had 89.2% accuracy in determining the desired working conditions for the whitening machine.

The abrasive rolls are easily withdrawn out of the top of the unit, because the cantilever main shaft design makes a bearing at the top of the machine unnecessary. The screens are of a 'lift away design' which makes screen changes quick and easy and can be performed without having to remove the frame from the machine. All other parts are easily accessible and readily interchangeable. 

rice destoner is used to remove the epidermis (aleuron) on brown rice to produce white rice that is ready to be marketed or cooked. This machine uses the screw extruder system in the cylinder which has the inner surface uneven. When brown rice fed into the cylinder it will jostle and rub against the cylinder surface which causes the epidermis to be eroded.
