The research objective was the establishment in an-alytical and empirical way of interrelation between the factors having impact on the efficiency of the process of drying proteinaceous and mineral granulate on the basis of soy and sapropelic raw materials. The research prob-lems were to receive analytical expressions characteriz-ing the process of drying of soy and sapropelic granu-late for accepted block diagram to carry out production inspection of the results on the basis of offered techno-logical and constructive and technological schemes, to obtain the data characterizing optimum and rational values of parameters of the process of drying of granu-late of set structure and properties in the drying cham-ber "ESPIS-4-Universal". The object of the research was the process of receiving dried proteinaceous and mineral granules on the basis of soy and sapropelic raw materials. The subject of the researches was the regu-larities of the process of receiving dried soy and sapro-pelic granules of set structure and properties. In the research the methods of system mathematical and ki-netic analysis, mathematical processing of results of the experiment and so on are used. On the basis of the analysis of merits and demerits of the existing schemes the block diagram of the line of preparation of dried pro-teinaceous and mineral granulate with use of the cham-ber dryer of periodic action is developed. Within theoret-ical analysis methodological approach providing the consideration of the process of drying of the product as real spatial system with weight decreasing in time was used. By drawing up corresponding differential equa-tions and their transformations the interrelations be-tween factors of studied process of drying of granules are established and the equations characterizing kinet-ics of drying of granulate of set structure and properties with justification of productivity of the dryer of chamber type are thereby received. To carry out production veri-fication of the main research results, the developed technological scheme for the production of granulate for cattle and pigs was adopted, as well as the design and technological scheme of the line with specific equipment in the form of 2 dispensers, a screw-type mixer-granulator and a dryer with 9 drying regimes "ESPIS-4-Universal". Optimum rational parameters of drying soy and sapropelic granulates were obtained: drying capaci-ty of 60-86 minutes with final moisture content of 8 % and average strength of 95.5 %.
