1. Experimental Purpose:
To verify the drying time of yam and to determine the yield ratio
2. Experimental Materials:
Drying box, yam, slicing knife, timer, electronic scale
3. Experimental Steps
1. Clean with fresh yam
2. The yam needs a knife to remove the outer skin
3. Cut the yam into raw materials of yam about 3m
4. Put the yam in an oven with a temperature of 60℃ for drying

5.Experimental Conclusions
The thickness of yam slices is about 2-3mm, and it is dried at a temperature of 60°C with
yam chips frying machine. After 12 hours, a dried yam with better color can be obtained.
After measuring, the moisture content of the yam before drying is 75%, the moisture content after drying is 6%, the moisture removal rate is 70%, and the yield ratio is about 3.3:1
