Before milling, rice from silos is cleaned again before moving to a rice destoner and paddy husker and turned into brown rice and rice husk. The rice husk will become fuel for electrical generation at the BioMass Power Plant (Bua Yai Bio Power Plant).

The brown rice is passed to the most advanced whitener to become “white rice” and “rice bran” that will be used in animal feed plant and rice bran oil plant later.

The white rice is further moved through the polisher for shiny and transparent grains, then to the length grader to separated the broken rices.


With the evolution in today technology, Tong Hua rice is processed through the most advanced color sorter in order to get the most refined white grain, free from any impurities.
