The energy consumption indicators of the technology of combining evaporation and drying of liquid products in a single unit were studied. The results of the approbation of this technology are presented on the example of the operation in industrial conditions of the "ИСАР-700" unit, developed at the Institute of Technical Thermophysics of the National Academy of Sciences of Ukraine. Analysis of thermo-technological processing characteristics as applied to producing dry powdered milk products with using the evaporation-type recirculation drier "ИСАР-700" has been performed. It has been shown that the given technology, which allows the performance of both evaporation and drying processes with the aid of the same spray drier, may be considered as a very efficient method of dehydration from viewpoints of energy saving and environmental protection. Thus, in the production of dry substitute for whole milk, 703 kWh were consumed for the evaporation process of 700 kg of moisture per hour by the "ИСАР-700" evaporation-drying unit. Electrical and thermal energy, i.e. 1.1 kWh of energy per 1 kg of evaporated moisture. These indicators testify to the high thermal efficiency of both the heat generators included in the "ИСАР-700" unit, as well as the practical implementation of evaporation and drying processes during the dehydration of dairy products by the spray method. Taking into account the significantly smaller (practically absent) emissions of powder into the environment, compared to the traditional technology of evaporation of dairy products in vacuum evaporators and drying of the concentrate in spray dryers, the absence of the need for steam, and therefore also in the boiler room, the absence of the need for large volumes of water for the operation of vacuum-evaporating devices, the absence of discharges into the sewage network of used water contaminated with dairy products, the technology of carrying out the processes of evaporation and drying of dairy products by the spray method in a single unit with its own autonomous heat generators can be considered as very effective, both from the point of view of energy consumption, and environmental cleanliness.
