RICE WHITENING MACHINE (MRW series) is our invention with the following feautures:
- Rice grains are abraded between the surface of the abrasive roller and abrading rubber bars.
- The air are blown into the slots close by the rubber bars to relieve the heat of rice and separate the bran completely.
- The abrading chamber is divided into many independent abrading columms; particularly the ribs of the screens make rice grain towards a fixed route in the abrading chamber.
- The gap between screen and abrasive roller can be adjusted without stopping machine.
 
RICE WHITENING MACHINE (MSW series) is our lastest invention with the following feautures:
- Feeding material by screw conveyor connected to the abrasive roller with screens surrounding. 
- The screen are separated by metal bars that divide the material chamber and the abrading chamber into ever columms.
- Air are blown into the material chamber and the abrading chamber through the slots next to the metal bars to shape abrading columms and separate bran completely from rice lengthwise.
