UNIVERSAL VACUUM DRYING CABINET Russian patent published in 2024 - IPC F26B9/06 F26B5/04 

FIELD: chemistry; microbiology; food industry.

SUBSTANCE: invention relates to food, chemical and chemical industry and can be used for vacuum sublimation and vacuum low-temperature drying of both frozen and non-frozen products of animal and vegetable origin, which are in non-liquid aggregate state. In process of vacuum sublimation or vacuum low-temperature drying for supply of heat energy to dried product in vacuum drying chamber instead of rigid heat-conducting shelves is used soft vapour-permeable fabric with heating elements, on which the dried product is placed. Electrically heated fabric with the unfolded product is rolled up, placed into the drying chamber and connected to the power supply.

EFFECT: increased area of heat exchange surface, simplified performance of operations of loading and unloading of product, as well as design of vacuum chamber, which together increases technological effectiveness of drying process.
