Simple processing of dehydrated potatoes and potato starch

This paper discusses the technical aspects of establishing a plant for dehydration processing of potatoes and potato starch. The authors first review socioeconomic factors to be considered prior to the construction of a processing plant and discuss aspects of potato composition which affect the yield and economics of processing. Potato selection standards and storage requirements are listed, and procedures and equipment used to select, store, wash, peel, cook, cut, dry, mill, and size potatoes in an International Potato Center pilot processing plant described. Attention is also given to equipment motor needs and a plant operation schedule. Similar steps and equipment used in producing potato starch are then detailed. Included in the text are diagrams and photos illustrating equipment design and function as well as suggested modifications to improve plant operation.
