Yes, you should sun-dry wheat grains before long-term storage. Learn how this crucial step reduces moisture content and prevents spoilage.

Yes, wheat grains should be sun-dried before storage to reduce moisture content, preventing mold growth and insect infestation, thus preserving their quality and extending their shelf life.
Detailed Explanation:
Sun-drying wheat grains is a crucial step in post-harvest handling. Freshly harvested wheat often contains a significant amount of moisture. High moisture levels create an ideal environment for the growth of mold, fungi, and bacteria, which can spoil the grains and make them unfit for consumption. Additionally, insects thrive in moist conditions and can rapidly infest and damage the stored wheat.
The process of sun-drying involves spreading the wheat grains in a thin layer on a clean, dry surface, such as a concrete floor or a tarpaulin, and exposing them to direct sunlight. The sun's heat evaporates the moisture from the grains, reducing their water content to a safe level, typically around 12-13%. This lower moisture content inhibits the growth of microorganisms and reduces the risk of insect infestation. Regular turning of the grains ensures even drying and prevents the formation of mold in localized areas. The duration of sun-drying depends on the intensity of the sunlight and the initial moisture content of the wheat, but it usually takes several days.
Pro Tip:
To ensure even drying and prevent spoilage, avoid piling the wheat grains too thickly during sun-drying. A thin, even layer allows for better air circulation and faster moisture evaporation.
