1. Clean onions: Before handling onions, make sure to wash them thoroughly to remove dirt and other impurities. This can be done by rinsing the onions under running cold water or soaking them in clean water. Then wipe it dry to ensure that no excess moisture is introduced during the drying process.

2. Cut the onions: Cut the onions into uniform slices or thin strips. This will help speed up the drying process and ensure that the onions dry evenly. You can use a knife or slicer to accomplish this step.

3. Arrange evenly: Arrange the cut onion slices evenly on the drying net, making sure there is enough space between them to allow air to circulate. This helps speed up the evaporation of moisture and the drying process.

4. Control the temperature: Choose the appropriate drying temperature according to the drying equipment you use and the thickness of the onions. Lower temperatures prevent the onions from overdrying or burning, while higher temperatures evaporate the water more quickly. Generally speaking, a temperature between about 50°C and 60°C is suitable.

5. Time control: The length of drying time also depends on temperature, humidity and thickness of onions. Generally speaking, onions need to be dried for 6 to 12 hours, but you should check the condition of your onions frequently to make sure they are drying without overdrying.

6. Store dried onions: Once the onions are completely dry, transfer them to an airtight container for storage. Make sure the container is dry to prevent the onions from absorbing moisture.
