Abstract

We made a sensitivity study of the potato flake process using the ERRC Food Process Simulator computer program with cost as the primary objective function. The study showed that labor was the largest component of the processing cost followed by capital related expenses. Pilot plant operation demonstrated the feasibility of reducing labor requirements. Capital related expenses could be minimized by using four drum dryers to more closely match the through put of the rest of the process. In addition, the drum dryers should be run as close to 8% moisture as possible without exceeding 8% to optimize the yield of finished product. This study demonstrates the feasibility of using the ERRC Food Process Simulator to do a sensitivity study of potato processing.
