Product Detail



CDA Rice Whitening machine is the latest invention with the following characteristics:

  • Rice grains are abraded between the surface of the emery-stone of a rotary cylinder and abrading rubber bars.
  • Currents of air are blown into the slots close by the rubber bars to relieve the heat of rice, and to separate the bran completely.
  • The abrading chamber is divided into many independent abrading columns; particularly the screen ribs make rice grains towards a fixed route in the abrading chamber.

There are two types of the machine:

  • CDA with automatic rubber adjuster: the automatic section adjusts the rubber bars towards the abrasive roller at a fixed speed correspondingly the wear of rubber bars during operating. The horn will alarm when rubber bars are worn out and the process of the operation of rubber bars will be stopped.
    For CDAC, all the adjustment is done on a touch screen.
  • CDS with manual rubber adjuster: the rubber bars are adjusted at the same time by a hand-wheel. The hand-wheel cannot be adjusted to move rubber bars towards the abrasive roller when rubber bars are worn out.


  • High percentage of whole rice, less brokens.
  • Husking paddy mixed in brown rice.
  • Finished rice with high whiteness.
