Application in Rice Whitening and Polishing
This SB combined rice milling machine is used to process paddy into white rice by integrating husking and milling functions in a compact unit. It is suitable for small commercial rice milling, not for industrial 20–1000 TPD plant positioning.
Core FunctionCompact milling / whitening unit for converting cleaned paddy or brown rice into white rice in smaller commercial lines.
Buyer ValueCombines key milling functions in a compact machine, helping small mills reduce layout complexity while producing marketable white rice.
Line IntegrationWorks after paddy separation and before polishing, grading, color sorting or packing, where brown rice is milled into white rice.
Process Result & Line Integration
How SB Combined Rice Milling Machine Fits in the Rice Milling Line
See how brown rice or pre-whitened rice is processed, how bran is removed and where the rice goes next.
Processing Action
Bran removal by friction and abrasion
Output / Next Step
White rice for polishing, grading, color sorting or packing
Key Features
For Rice Whitening, Bran Removal and Surface Finish
Processes brown rice into white rice and, where required, improves the final rice surface before grading and sorting.
Controlled Whitening
Removes bran layer while balancing milling pressure, output and broken rice rate.
Air and Bran Handling
Air suction and bran discharge help keep the milling chamber cleaner and reduce blockage risk.
Appearance Upgrade
Polishing equipment can improve rice surface brightness and market presentation after whitening.
Working Principle
How It Works in the Process
Use emery/iron roller and air flow to remove bran layer and whiten brown rice.
Input
Brown rice or pre-whitened rice enters the whitening or polishing section.
Milling / Polishing
The machine removes bran or improves the rice surface according to the required finish.
Bran & Dust Removal
Bran, dust or polishing by-products are separated through the designed outlets.
Output
White or polished rice moves to grading, color sorting or packing.

Whitening & Polishing Selection
How to Choose Rice Whitening or Polishing Equipment
Choose according to brown rice condition, required whiteness, bran removal, broken-rice control and finished rice appearance.
Milling StageUse rice whiteners to remove bran from brown rice; use polishing equipment when better surface brightness is required.
Rice Variety & QualityMatch emery roll, iron roll, jet-air or water polishing structure to long grain, short grain and final quality target.
Bran & Heat ControlCheck air suction, bran discharge and milling pressure to reduce heat, blockage and excessive broken rice.
