Grading & Sorting Selection
How to Choose Rice Grading or Color Sorting Equipment
Select by the defect you need to remove: broken rice, size variation, length difference, thickness difference or color defects.
Broken Rice & SizeUse white rice graders or rotary graders when the goal is to separate whole rice and broken rice by size.
Length or ThicknessUse length graders or thickness graders when rice shape consistency is important for the target market.
Color DefectsUse a color sorter when yellow, chalky, black, spotted or foreign-color grains must be removed.
