1. Remove all packaging materials before use, then rinse with clean water and dry. 2. Storage after use: After cleaning after use, dry the drying rack before storing. 3. Cut the food into thin slices. The drying time of the food depends on its thickness. The thinner the food, the faster it will dry. Place the sliced ingredients on the baking rack. Even if you do not have enough food to put the drying racks full, please install all the drying racks and place the food on the top level. For example, you only need to bake one layer, but please fill all the drying racks and ensure that the food that needs to be dehydrated is on the top layer. 4. After putting all the food in, close the top cover. Adjust to the required temperature. Fruits and vegetables should not exceed 60 degrees. Adjust the drying rack according to the drying conditions of the food. For example, the closer it is to the power supply, the faster it will dry. You can adjust the drying rack as needed.
