The Sago industries are traditional agro-based processing industry with huge employment potential in India. Tapioca roots are one of the richest sources of starch and it contains 30% of starch. The sago industries are extracted the starch from tapioca roots using conventional method and mechanical method. The recovery of starch from tapioca root is 16-18% by conventional method and 22-25% by mechanical method. The average loss of starch is only 5% while peeling the roots using mechanical peeler where as the starch loss is 10-15% in manual peeling. In mechanical process, the time required for e
