Why is it necessary to dry grains before storage

Oct 6, 2023

Drying grains before storage is a crucial step in the agricultural process. Whether you are a farmer or a business involved in grain production or trading, understanding the importance of drying grains cannot be overstated. In this article, we will explore the reasons behind drying grains before storage, the methods involved, and the implications it has on quality and spoilage prevention.

Preserving Grain Quality

Grains, such as wheat, corn, rice, and barley, are highly valuable commodities, and their quality directly impacts their market value. Properly drying grains before storage is essential to maintain their quality by preventing mold growth, insect infestation, and mycotoxin formation.

When grains are harvested, they typically contain a high moisture content. If these grains are stored without proper drying, moisture creates a favorable environment for mold and fungi to thrive. Mold can lead to a degradation in quality, affecting the taste, nutritional value, and appearance of the grains. Furthermore, certain molds produce mycotoxins, which are toxic substances that can pose serious health risks when consumed by humans or animals.

Drying grains effectively reduces the moisture content, creating unfavorable conditions for mold growth and reducing the risk of mycotoxin formation. By controlling moisture levels, farmers and grain traders can maintain the marketability and safety of their grain products.

Preventing Spoilage

Grains that are not properly dried before storage are prone to spoilage. Spoilage can occur during storage due to the presence of moisture, heat, and pests. Moisture inside storage facilities can result in grain clumping, fermentation, and heating, leading to spoilage and economic losses.

A high moisture content in stored grains also creates a breeding ground for pests, including insects and rodents. These pests can consume and contaminate the grains, causing further deterioration and reducing the overall quality.

Drying grains to the appropriate moisture levels significantly reduces the risk of spoilage. Dry grains discourage pest infestation and minimize the chances of fermentation or heating, ultimately ensuring that the grains remain viable for longer periods.

Drying Methods and Techniques

Various methods and techniques are employed to dry grains effectively. The choice of drying method depends on several factors, including the type of grain, environmental conditions, and available resources. Some common drying methods include:

  • Natural Air Drying: This method involves allowing the grain to dry naturally, by exposing them to ambient air. The grains are spread in thin layers, facilitating airflow and moisture evaporation. Natural air drying is a cost-effective method, but it requires favorable climatic conditions and may be slower compared to other techniques.
  • Artificial Drying: Artificial drying involves using mechanical devices, such as grain dryers, to reduce the moisture content of the grains. Grain dryers employ heated air or a combination of heat and airflow to accelerate the drying process. This method is advantageous in regions with high humidity or when quick drying is required.
  • Sun Drying: Sun drying is a traditional method that relies on solar energy to dry the grains. The grains are spread on a clean surface under direct sunlight, allowing the heat to evaporate moisture. While sun drying is a low-cost method, it is highly dependent on weather conditions and may not be suitable for all types of grains.

It is important to note that each drying method has its own benefits and considerations. Farmers and grain handlers should evaluate their specific requirements and opt for the most appropriate drying technique to achieve optimal results.


Ensuring grains are properly dried before storage is essential to maintain quality, prevent spoilage, and uphold safety standards. By carefully managing moisture levels, farmers and grain traders can protect their investment and deliver high-quality products to the market. Utilizing appropriate drying methods and techniques, such as natural air drying or artificial drying, enables effective control of moisture content and reduces the risk of mold growth, mycotoxin formation, and pest infestation.
