An onion dryer is a specialized machine used in agriculture and food processing industries to efficiently dry onions. Onions are a widely cultivated crop globally and are used in various culinary dishes, making their preservation crucial. The process of drying onions involves reducing their moisture content to extend shelf life, prevent spoilage, and retain nutritional value and flavor.

Drying Chamber: The core of an onion dryer where onions are placed for drying. It typically contains trays or racks on which onions are spread out evenly.

Air Circulation System: Utilizes fans and ducts to circulate heated air throughout the drying chamber. This ensures even distribution of heat and moisture removal from the onions.

Heating Mechanism: Often powered by electricity or gas, the heating system generates the heat required for drying. Controlled temperature settings are crucial to prevent over-drying or damaging the onions.

Control Panel: Allows operators to set and monitor drying parameters such as temperature, humidity, and drying time. Modern dryers may feature automated controls for precise operation.

Air Exhaust System: Removes moist air from the drying chamber, maintaining optimal drying conditions and preventing condensation.
