I. Preliminary work
Clean the sweet potatoes first, then put them in the boiler for cooking. Take out the sweet potatoes when they are about seven or eight ripe, and wait for them to cool before slicing manually.
In the slicing process, first of all, the thickness must be consistent, and secondly, the specifications of the sweet potato chips should not be too different.
After these steps are completed, the cut sweet potato chips are placed on a rack where the materials are placed. Achieve uniform thickness and neat placement
Second, the drying process
1. Put the sweet potato chips inside the oven when the temperature in the oven rises to about 30 ° C. The set temperature is 40 ° C. The drying time is one to two hours.
2. The temperature is set to 55 ° C. The drying time is two hours.
3. The temperature is set to 65 ° C. The drying time is two hours.
4. The temperature is set to 70 ° C. The drying time is one hour.
5. Turn off the power and remove the material after one hour.
Packaging into bags
After taking out the materials, the sweet potato chips need to be completely cooled before being packed into the bag. In general, the batch drying time is about 8 hours, and the maximum temperature does not exceed 70 ° C.
