We begin the process with getting the rice directly from farmers, we source from the best paddy fields possible. Every single grain has to go through strict standard quality control and advance production processes with high technology macinery. The result is the rice in the best quality internationally.


Raw Material Receive

Raw Material Recieve

We have carefully sought out the best source of Thai Jasmine Rice and we buy the rice paddy directly from farmers. The grains have to pass through physical and chemical inspection before entering the whole production process in order to ensure the purity of the rice.

All the paddies are cleaned to rid of any impurities, then they are proceeded to the Dryer to decrease the moisture content before getting stored in hygenic silos.


Rice Mill

Rice Mill

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, Tonghua rice is processed through the most advanced color sorter in order to get the most refined white grain, free from any impurities.




For quality assurrance, every grain of Tong Hua Bua Yai’s rice has to go through rice refining process, from destoning, polishing, sifting, length grading, and color sorting before being packaged.
