2. Cut the peeled yam into pieces with a thickness of about 0.4 cm with a knife. When cutting, the thickness should be uniform. Too thick is not easy to dry, while too thin is easy to burn during baking.
3. Preheat the burning box and set the temperature at 120. Spread a layer of tin foil on the baking tray, put the cut yam slices on the tin foil, put them in the oven, bake for 20 minutes, then take them out and turn them over, and bake for about 20 minutes. At this time, the yam tablets inside can be dehydrated, and the taste can become crispy and delicious, which is much better than the purchased dried yam slices.
