Application in Rice Whitening and Polishing
This double-body MNJ iron roller rice mill is used to increase rice whitening capacity with a left-right double-body structure. It is suitable for higher-output commercial rice milling plants.
Core FunctionRice whitening / milling for removing the bran layer from brown rice and producing white rice.
Buyer ValueProvides controlled friction or abrasion for stable whiteness, lower broken rate and cleaner bran discharge when matched with air suction and bran collection.
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 MNJ Side-by-Side Iron Roll Rice Whitener 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.
Technical Specifications
Technical Specifications
MNJ Side-by-Side Iron Roll Rice Whitener specifications are selected by milling capacity, rice variety, whitening degree, bran removal method and whether polishing or grading follows downstream.
| Item | Specification | Selection Note |
|---|---|---|
| Core function | Whitening, milling or polishing rice according to the machine type | Confirm whether the input is brown rice or pre-milled white rice |
| Capacity | Model-specific commercial rice milling capacity | Match upstream husker/separator and downstream grader |
| Power / air system | Model-specific motor and bran/dust removal system | Confirm local voltage and dust collection plan |
| Line integration | Installed before grading, color sorting and packing | Choose single-pass or multi-pass layout by finished rice quality target |
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.

FAQ
Common Questions
What is the difference between whitener and polisher?
A whitener removes bran; a polisher improves the surface quality of white rice.
Emery or iron roller?
Selection depends on rice variety, milling stage and required finish.
Can it be used in an automatic plant?
Yes, most models can be matched in a complete rice milling line.
