2.Arrange the lettuce: Arrange the cut lettuce evenly on the tray of the dryer, taking care to avoid overlapping, to ensure that each slice of lettuce is fully heated.
3.Drying stage: Start the drying equipment and start the drying process. In the drying process, the temperature and humidity should be adjusted in a timely manner according to the degree of dryness of the lettuce and the actual situation of the equipment. Generally speaking, the drying time can range from a few hours to a dozen hours, depending on the variety of lettuce, the thickness of the slices and the performance of the drying equipment.

When the lettuce is dried to a certain extent, the appliance can be turned off and the dried product can be removed. Dry products are placed in a ventilated place to cool naturally to room temperature before packaging and storage. When packing, choose a bag with good sealing and add an appropriate amount of desiccant to prevent moisture and mildew of dry products.
