Cleaning
Because the uneven quality of raw paddy, the purpose of cleaning is to remove all kinds of impurities in the paddy through various cleaning equipment, making it meet the quality requirement of further processing.
Sifting:
Removing large, small and light impurities in rice according to their different size and shape from the paddy.
Gravity grading:
Separating impurities base on their differences in density, friction coefficient, suspended speed and other physical characteristics with the paddy through the gravity grading equipment.
Magnetic separation:
By putting the paddy through the magnetic field, the ferromagnetic impurities are separated hence avoid damaging to the processing facilities.
Features
Low power consumption;
Good cleaning effect;
Easy operation, low maintenance.
Hulling & Separating
INTRODUCE:
The cleaned paddy enters into the hulling process, and the husks are removed by the hulling equipment to obtain pure brown rice.
Features
Complete separation of paddy and husks;
Low broken rate.
Milling
INTRODUCE:
Rice milling is the process of to separate and remove the husk and bran to obtain the edible portion of paddy. It is the process which transforms paddy into edible rice. The process has to be accomplished with care to prevent excessive breakage and improve the quality of rice.
To reduce breakage and the grain temperature during the whitening process, the paddy is normally passed through several whitening and polishing machines connected in series. The arrangement of machines to process the rice is dependent on the physical characteristics of paddy. Proper sequencing and arrangement of the machines will help lower the broken rate. 
According to the quality requirement of end product, we provide reasonable configuration and arrangement of machines in the process design ensuring the quality standard of finished product with lower energy consumption. 
Features
High yield with less broken rice;
Further processing
INTRODUCE:
After being processed by the mill, the rice can still contain some bran powder, broken rice and discolored rice, which would affect the quality of the finished product. The purpose of the further processing section is to remove them in order to ensure the quality of the finished rice.
Rice grading:
The purpose of rice grading is to separate broken rice which are not up to the standard quality requirements. The common equipment is the rice grader, which can separate rice into different grades.
Polishing:
To remove the bran powder attached to the surface of rice, so as to make the rice clean and bright.
Color sorting:
The color sorter adopts optoelectronic technology, using the difference of reflection rate between discolored rice and white rice to separate the rice with different colors, thus ensuring the quality of the finished product.
Features
Complete removal of rice with different colors and broken rice;
The finish product has good appearance.
