Object of study - processes in the processing of colloidal capillary-porous materials. The aim of the work is to study the process of heat and mass transfer during dehydration of colloidal capillary-porous materials (CCPM) during convective drying, which will reduce energy costs by utilizing and returning the energy of waste material flows to the technological process, to intensify heat and mass transfer during dehydration by creating optimal values of mass transfer head during the entire drying process under conditions of the thermal and humidity state of the material changing in time, and on this basis to develop new energy efficiency. Experimental studies of dehydration kinetics and energy consumption, thermal stability and decomposition were carried out, and the thermal and physical characteristics of raw materials and dehydration products, their physical, chemical and sorption properties were obtained. The research covers the entire range of issues from raw materials to finished dehydrated CCPM. Based on the report's findings, energy-efficient heat technologies and heat pump dryers for processing colloidal capillary-porous materials have been developed. These allow to obtain a dried product with high quality and long-term storage capacity. The developed technologies have been granted patents of Ukraine. The results of the work allow us to modernize existing convective dryers by equipping them with modern energy-saving heat transfer systems, which will help improve the quality of Ukrainian products and their competitiveness in international markets.
