What is a Winnower?

A winnower is a machine that works on the principle of air flow to separate lighter impurities from heavier grains. When grains are poured into the machine, a controlled stream of air blows away lighter materials while the heavier grains fall separately. This process helps in cleaning grains like wheat, paddy, maize, and pulses efficiently.

⚙️ Types of Winnowers

1. Manual Winnower:
Operated by hand, suitable for small-scale farms and traditional farming areas.

2. Pedal Operated Winnower:
Works with foot operation and is more efficient than manual winnowing.

3. Power Operated Winnower:
Runs on an engine or motor and can clean large quantities of grain quickly.

4. Combined Winnower and Cleaner:
A modern type that performs both cleaning and winnowing in one process for better efficiency.

🌾 Benefits of Winnowers

• Separate grains from husk and dust effectively.

• Improve the purity and quality of grains.

• Save time and labor compared to traditional winnowing methods.

• Reduce post-harvest losses and increase productivity.

• Prepare grains for safe storage or further processing.
