Abstract
This paper describes the technological scheme of apple juice pasteurization process are considered. The issues of modernization of the existing technological scheme of apple juice pasteurization process are considered. Namely, an improved energy-functional scheme of a combined type with complete heat recovery was obtained. The value of technical and economic indicators is determined. A comparative analysis of the received scheme with the scheme with an additional cooler was carried out. The chilling machine is a combined type, ie, with simultaneous working out of heat and cold for the needs of production. Therefore, it is more efficient than the refrigeration system with an additional cooler, however, it has a compressor with an electrical power of 173 kW and heat exchange equipment of greater power. A variant of a circuit solution may be suitable for implementation in those enterprises where, in addition to pasteurization of process streams, a large amount of hot water with a temperature potential of up to 90 ºС is required. Both circuit solutions that have been developed and analyzed are conceptual and can be adjusted in terms of energy efficiency and basic technical and economic indicators in the design and implementation process. They can also be used in the design of new industries, where there are pasteurization and cooling processes and in the reconstruction of old enterprises in order to improve their energy efficiency.
