METHOD FOR CONCENTRATING OF LIQUID FOOD PRODUCTS IN CONTINUOUS FLOW Russian patent published in 2007 - IPC A23C1/06 A23L2/12 B01D9/04 

FIELD: process used in food-processing, milk, brewing, chemical, oil-and-gas and other branches of industry for concentrating of liquid food products by moisture freezing.

SUBSTANCE: method involves feeding liquid food products in continuous flow; providing reaction with carbon dioxide; separating concentrate from carbon dioxide granules with frozen moisture thereon; feeding liquid carbon through nozzle of jet-type ejection unit; obtaining at nozzle outlet high-speed linear two-phase flow of solid phase in the form of granules and vapors. High-speed rectilinear mode is created for liquid food product flow within mixing chamber of ejection unit by providing reaction with two-phase carbon dioxide flow to thereby enable dispersion of product by vapors issued from nozzle and increase of heat-and-mass exchange surface.

EFFECT: intensified moisture crystallization process owing to increased heat-and-mass exchange surface, and provision for creating of stable product and carbon dioxide flow.
