The methodology of calculation of multistage hydroclone units in production of potato starch with use of new hydroclone modules is developed. The method of definition of number of apparatus at each step of the starched line, based on the joint solution of the equations of material balances as on steps separately, and all installation as a whole is offered. This method provides uniform distribution of material streams on all devices. In the methodology limiting factors of real starched plants are considered. Mathematical modeling is based on results of industrial and laboratory researches of new hydroclone modules on starched suspensions in wide intervals of influencing factors. Types of basic hydroclone modules and their optimum constructive characteristics are defined. Account characteristics of the chosen hydroclone TVP-25 and TVP-63 modules are provided. The standard equations of material balances of the separate steps entering into the general system of the equations are shown. Various versions of new technological schemes are counted and their main working parameters are determined. As a result one of the calculated 9 step hydroclone units is introduced on Yalchiksky JSC «Chuvashjenkrakhmal» and Vurnarsky starched plant instead of earlier used 14 step units.
