Grading Sifter SF-31

It uses a woven screen to separate head rice, broken grains, and bran balls by size.

Note that this machine was designed specifically for short and medium grains — it is not suitable for processing long grains.

Product Features

High Precision Sifting

Our grading sifters refine milled rice using the complex horizontal oscillation of an inclined screen combined with a circular motion. The screen angle is adjustable between 5–8 degrees.
