The rice husking process
Husking removes the outer husk from paddy to produce brown rice. The resulting stream requires separation before brown rice moves on to whitening.

Input and output
| Stream | Material |
|---|---|
| Input | Prepared paddy |
| Main product | Brown rice |
| By-product | Detached husk |
| Material to separate | Remaining unhusked paddy |
How the stage fits
Cleaning and removal of unwanted dense material belong upstream. Downstream separation directs brown rice forward and unhusked paddy back to the appropriate husking route.
Machine used
A rubber roll husker is one machine type used for this transformation. Its documented settings and roll specifications apply to that design, not to every husker.
Important observations
Record the incoming batch, feed consistency, remaining paddy and any change in broken grain. Do not evaluate husking by the appearance of white rice because bran removal happens at another stage.
Common problems
If too much paddy remains, inspect the sampling method and input conditions before considering settings. If newly broken grain increases, compare roll condition and operating records with the documented baseline.
Quality check
Keep an inlet and outlet sample from the same run. This helps distinguish pre-existing damage from a change introduced at husking.
Next process
The next material-control task is paddy separation. Follow the brown-rice stream toward whitening only after checking that routing and separation are functioning as intended.
