Spray dryer features have been analysed in this paper, and criteria for drying process kinetic curves analysis have been grounded. An algorithm for the performance of an electronic system which controls the spray dryer on the basis of the process model has been suggested. An algorithm of a subprogram for the drying process kinetic curves assessment on the basis of particular assessment criteria has been presented. An algorithm for the specialised controller performance has been produced. A structural scheme of a spray drying control electronic system has been developed. It is composed of a personal computer simulating the drying process through a model, and a specialised controller collecting data about the process parameters, and controlling the actuating units.
