Grain Drying and Storage

The primary purpose of drying grain is to reduce moisture content, preventing spoilage, mold growth, and insect infestation.
Maintaining a relative humidity of 70% or lower in storage structures prevents moisture accumulation and preserves grain quality.

Drying Methods

Heated air drying utilizes heat to vaporize water from grain, efficiently lowering moisture content.
Sundrying is a cost-effective method that leverages natural sunlight, requiring no energy for heating compared to heated air-drying.

Storage Guidelines

The recommended moisture content for safe storage of cereal crops is typically around 13-15% to prevent deterioration.
Peanuts and soybeans are particularly sensitive to moisture, with a significant risk of spoilage if stored improperly.

Drying Timing

It is essential to start the drying process as soon as possible after harvesting, ideally within 24 hours, to minimize spoilage risk.

Optimal Conditions

The optimal relative humidity for storage structures is preferably below 50% to ensure adequate preservation of stored grains.
Reducing moisture content in grains is crucial for extending shelf life and maintaining grain quality during storage.

Learn about the importance of drying and proper storage techniques to prevent spoilage and maintain grain quality. Understand the ideal moisture content levels for safe storage and common drying methods.
