Considering the current situation in the energy sector of Ukraine, the urgent need to improve and develop energy-efficient thermal technologies for dehydration of plant raw materials is urgent and timely, which would ensure minimal energy consumption and high quality of the final product. The processing of vegetable raw materials into dried products is important for the sustainable development of the food industry. Cultivated Pleurotus eryngii mushrooms, which are valued for their high content of protein, carbohydrates, unsaturated fatty acids, vitamins and other nutrients, etc., are increasingly relevant in the mushroom industry on the world food market. It is important, in order to optimize energy consumption during dehydration and to select rational equipment, in addition to experimental studies, to perform theoretical calculation analysis of heat and mass transfer based on mathematical models. The article provides a theoretical and experimental analysis of the drying kinetics of colloidal capillary-porous materials. To determine the characteristics of the convective drying process, in addition to experimental studies, numerical modeling of this process was performed, which is performed on the basis of the numerical solution of the system of heat and mass transfer equations in colloidal capillary-porous materials. The calculation model can be used for the approximate determination of the main characteristics of the drying process of colloidal capillary-porous materials.
