METHOD AND DEVICE FOR CONTINUOUS DEHYDROFREEZING OF LIQUID PRODUCTS Russian patent published in 2017 - IPC F26B5/06 F26B3/12 F26B3/30 F26B17/10 

FIELD: technological processes.

SUBSTANCE: method of continuous dehydrozreezing of liquid products, wherein the primary liquid product is heated to the highest probable temperature, is injected into the upper portion of the vacuum chamber through a nozzle with a droplet size of not more than 0.05 mm, which results in a spontaneous freezing of a product due to evaporation of moisture contained in it, then it is feeded into the vacuum drying chamber with an infrared (IR) heater under action of gravity, where the drying of the product is carried out due to ice sublimation therein during lingering of vapours in the countercurrent flow at low temperatures, the dried product is removed from the chamber together with a portion of the vapour stream. Device for method implementing is made in the form of a vacuum chamber positioned vertically and divided into two parts - a vacuum cooling chamber with a spray nozzle installed in its upper part and a vacuum drying chamber with IR-heater installed in it, wherein both chambers are separated against each other by a partition in the form of a funnel with an opening at the center and contain vapour taps connected together by a vacuum line which has an outlet for connection to a vacuum pump.

EFFECT: reduced power consumption, improved performance.
