The third step is soaking: Immediately soak the peeled sweet potatoes in clean water at room temperature for one hour.

The fourth step is steaming: Remove the soaked sweet potatoes and place them in a sealed steamer for about two hours, until they are completely soft.

The fifth step is cutting: Cut the steamed sweet potatoes into even pieces or strips.

Finally, dry them. Arrange the cut sweet potato strips evenly on trays, then place them on a cart and roll them into the drying room. The drying process is then set to an initial temperature of 65°C for four hours.
