Mesh belt dryers are commonly used to dry a variety of food products, including onions. The dryer transports food through the drying chamber via a conveyor belt to achieve uniform drying. The effectiveness of onion drying is determined by multiple factors:

1. Temperature and humidity control: The drying of onions requires appropriate temperature and humidity control. The mesh belt dryer can intelligently and accurately adjust temperature and humidity to provide good environmental conditions.

2. Drying time: Drying time that is too short or too long may affect the quality of onions. The appropriate time can be set according to the characteristics of onions.

3. Hot air circulation: The mesh belt dryer is equipped with a hot air circulation system, which helps to distribute heat more evenly and improve the drying effect.

4. Ventilation performance: Good ventilation performance helps to eliminate moisture in the drying room, ensuring that onions can be dried quickly without getting damp.

When using a mesh belt dryer, it is recommended to adjust relevant parameters according to the specific requirements and process flow of onions to achieve the best drying effect. Maintain and clean equipment regularly to ensure proper operation and long-term stability.
