Sweet potato roots can be processed into dehydrated forms such as dried chips and flour for storage and uses in food preparations. Sweet potato drying usually performed traditionally with the use of sun, which is a time consuming method (about 56 hours) and produces an inferior quality product with high health risk due to high contamination. The most employed way to reduce the drying time and obtain good quality product is the use of mechanical dryers, and it also lowers the product mass and volume which improves the efficiency of storing, packaging and transportation. And hot air drying is commonly used in producing sweet potato dried chips which are pulverized into flours. Process operations for processing sweet potato dried chips and flour involve cleaning,trimming, washing, slicing, drying, milling, packing and storage.
