VACUUM SUBLIMATION DRYING METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2024 - IPC F26B5/06 F26B9/06 

FIELD: food industry.

SUBSTANCE: group of inventions can be used for vacuum thermal treatment, sublimation drying of food products with simultaneous disinfection of the chamber. Method of vacuum sublimation drying involves loading a food product with a high moisture content into the chamber and drying the loaded product in a sublimation drying mode and consists in the fact that after the product is loaded into the chamber, the food product is thermally treated, drying chamber inner surfaces disinfection is carried out simultaneously with loaded product thermal treatment, after thermal treatment, the product is subjected to a freezing and/or self-freezing process, after which the product is dried in a sublimation mode. Also disclosed is a vacuum sublimation drying apparatus for implementing the method.

EFFECT: invention will make it possible to combine processes of thermal treatment of food product, disinfection of chamber and defrosting of desublimator, reduce labor costs and reduce the level of bacterial contamination of the dried product; besides, the proposed technology allows to significantly improve organoleptic indices of drying objects, for example, meat, meat products by means of obtaining more tender and soft structure.
