What is a Dryer?

A dryer is a machine used to reduce the moisture content of harvested crops to a safe level for storage. It works by passing heated air through the grains, which removes the excess water content. Dryers are commonly used for crops like rice, wheat, maize, pulses, and oilseeds. By using dryers, farmers can store their produce safely for longer periods without the risk of damage.

⚙️ Types of Dryers

1. Sun Dryers:
Traditional method where crops are spread under the sun for natural drying. It is cost-effective but depends on weather conditions.

2. Batch Type Mechanical Dryers:
Used for small and medium-scale drying. Crops are loaded, dried with hot air, and then unloaded after drying.

3. Continuous Flow Dryers:
Used for large-scale drying. Grains move continuously through the drying chamber while hot air passes through them.

4. Fluidized Bed Dryers:
Modern dryers that use air pressure to keep grains in motion during drying, ensuring uniform moisture removal.

🌾 Benefits of Dryers

• Remove excess moisture and prevent fungal or bacterial attack.

• Increase storage life and maintain grain quality.

• Reduce post-harvest losses caused by improper drying.

• Save time compared to traditional sun drying.

• Improve overall efficiency in grain handling and storage.
