Abstract
Description
Technical Field

[0002] Freshly harvested rice typically has a high moisture content, generally around 18% to 25%. However, the recommended moisture content for safe storage is usually around 13% to 14%. Rice dryers effectively remove moisture from rice through heating and ventilation, bringing it to a safe storage standard. High-moisture rice is prone to overheating, mold, and insect infestation during storage. After drying, the appropriate moisture content disrupts the growth and reproduction environment for microorganisms and pests, allowing for smoother processing. During milling, rice with the right moisture content results in better hulling and peeling, producing rice with higher integrity and a better appearance.
