The results of research on the development of a new method of thermal sterilization of canned products with heat recovery and the design of the device for its implementation are presented. The shortcomings of the traditional sterilization regime have been studied and identified, and taking them into account, the regime of multilevel high-temperature thermal sterilization of grape compote in SCO 1-82-1000 glass jars with heat recovery, which provides the required level of industrial sterility and reduces the duration of heat treatment, has been developed. The device for multilevel high-temperature heat treatment has been designed. The developed technology has advantages, being that the product is heated from the entry temperature level to almost 90–93°C with the simultaneous cooling from 100 to 63–65°C carried out by heat exchange between the very glass jars with different temperatures, which appear simultaneously in the chambers with a heat carrier, the temperature of which for some is higher and for others is lower by 25–27°C.
