A Paddy Separator is a vital machine used in rice milling plants to efficiently separate unhusked paddy (rough rice) from brown rice after the husking process. It ensures that only properly dehusked grains move forward in the milling process, improving overall product quality and yield.
The separator operates using differences in specific gravity, surface friction, and grain movement characteristics between paddy and brown rice.
The working of a paddy separator is based on gravity and oscillation:
- Mixed material (paddy + brown rice) is fed into the machine
- Oscillating trays or decks create movement
- Due to weight and friction differences:
- Brown rice (heavier) settles downward
- Paddy (lighter) moves upward
- The machine separates output into:
- Pure brown rice
- Pure paddy
- Mixed grains (recycled for reprocessing)
This process ensures efficient separation with minimal grain loss.
