The paper deals with the optimization of the drying process in the drying plant Proctor & Schwartz at drying potato chips for food purposes. The dried chips of Agrie variety were 10 x 10 x 3 mm in size. The construction design of the drying plant was that of a convection multizone drier. The drying process analysis is to determine the correlation between the relative water content and specific moisture of to-be-dried material, to-be-dried material mass flow and specific intensity of to-be-dried material transfer of moisture mass (drying rate) and the used temperature regimes of the drying plant. It is obvious from the analysis that the monitoring of the moisture content in the course of drying is a basic index for timely adjustment of basic parameters of the drier, which can to a considerable extent affect the quality of dried potato chips.
