Double Body Paddy Separator

Double Paddy Separator: Improve Rice Milling Efficiency and Increase Head Rice Yield

In modern rice milling plants, efficient separation of paddy rice and brown rice is one of the most critical processes affecting milling performance and finished rice quality.

The Double Paddy Separator is a high-efficiency rice separation machine designed to separate unhusked paddy from brown rice after the husking process. By utilizing differences in specific gravity, friction coefficient, and particle movement characteristics, the machine achieves highly accurate separation while minimizing rice loss.

As a key machine in complete rice milling lines ranging from 30T/D to 500T/D, the Double Paddy Separator helps rice millers improve production efficiency, increase head rice yield, reduce recirculation load, and optimize overall plant performance.

What Is a Double Paddy Separator?

A Double Paddy Separator is an advanced gravity-type separation machine that divides mixed material from the rice husker into:

• Pure Brown Rice
• Pure Paddy Rice
• Small Amount of Mixed Material

The machine adopts a double-body structure, effectively doubling the separation area and significantly increasing processing capacity compared with traditional single-body separators.

This design ensures:

✔ Higher separation accuracy

✔ Larger processing capacity

✔ Stable continuous operation

✔ Lower power consumption

✔ Reduced rice loss

Why Is Paddy Separation Important?

After husking, the discharged material contains:

• Brown Rice
• Unhusked Paddy
• Small Impurities

If unhusked paddy enters the rice whitening section directly, it can:

• Reduce milling efficiency
• Increase broken rice rate
• Damage whitening rollers

• Lower final rice quality

The Double Paddy Separator eliminates these issues by accurately separating paddy before milling.

Benefits

✅ Increase head rice recovery

✅ Reduce broken rice generation

✅ Improve milling efficiency

✅ Protect downstream equipment

✅ Lower operating costs

✅ Enhance finished rice quality

Double Paddy Separator Working Principle

The machine operates based on the difference in:

• Density
• Surface friction
• Flow behavior

Separation Process

1. ✅ Mixed material enters the feed hopper.
2. ✅ The material is evenly distributed onto specially designed sieve plates.
3. ✅ The reciprocating movement causes stratification.
4. ✅ Brown rice moves in one direction.
5. ✅ Paddy rice moves in the opposite direction.
6. ✅ Mixed material is automatically discharged and recycled.

The double-body design provides a larger separation surface, ensuring higher separation accuracy and stable operation even under heavy loads.
