Techno economic analysis of the production of potato powder applying potato starch purification system in Japan

To implement the technology for producing potato powder, significant investment is required. This study evaluated the techno-economic feasibility of the dried potato powder production process, based on a scenario developed in a starch plant process in Japan. The simulation was performed with SuperPro Designer® software. The annual production volume and the unit production cost were estimated to be 15,786,585 kg and 1056 Japanese yen/kg, respectively. According to economic evaluation indicators—the gross margin, return on investment, payback time, internal rate of return, and net present value (at a 7
