The usage skills of onion drying production line mainly include the following aspects:

1. Raw material selection and processing: Choose fresh, healthy, and tightly structured onions as raw materials. When slicing, you can use a slicer to cut the onions into thin slices with a thickness of 2 to 3 mm to improve drying efficiency.

2. Preheating and temperature control: Before using the drying equipment, preheating is required to ensure that the internal temperature of the equipment reaches the set value. During the drying process, the temperature must be strictly controlled, generally set between 55 and 60°C. Too high a temperature will destroy the nutritional value of onions, and too low a temperature will affect drying efficiency.

3. Humidity control: Onions have a high moisture content, so humidity needs to be controlled during the drying process. By controlling humidity, you can ensure that onions are fully dehydrated during the drying process while maintaining their nutrition and quality.

4. Ventilation and circulation: Good ventilation and circulation should be maintained inside the drying equipment to ensure that the onions are heated evenly during the drying process.

5. Maintenance and maintenance: Drying equipment needs to be maintained and maintained during long-term use to ensure its normal operation and extend its service life. Clean and inspect the equipment regularly, and replace worn parts and consumables in a timely manner; at the same time, pay attention to the lubrication and rust prevention of the equipment to ensure that the equipment operates in good condition.

By mastering the above skills and using the onion drying production line rationally, the onion drying efficiency and quality can be improved, production costs can be reduced, and greater economic benefits can be created for the enterprise.
