METHOD AND DEVICE FOR CONCENTRATING SOLUTIONS BY FREEZING OUT Russian patent published in 2013 - IPC B01D9/04 A23L2/08 

FIELD: medicine, pharmaceutics.

SUBSTANCE: group of inventions relates to food and pharmaceutical industry and is intended for separation of components in ideal solution. Method of concentrating solutions by freezing out includes crystallisation of solution with the following separation of concentrate from solvent crystals. In frozen out solution, which has temperature not less than temperature of liquidus, direction of crystallisation is led: if density of concentrated solution is less than density of initial solution, predominantly opposite to force of gravity; if density of concentrated solution is higher than density of initial solution, predominantly co-directionally to gravity force. Device for concentrating solutions by freezing out contains adsorbent of solution crystallisation heat, heat insulator, which prevents environmental impact on solution freezing out, devices for compensation of heat expansion of substances and removal of concentrated solution. In device for concentrating solutions by freezing out absorbent of solution crystallisation heat is placed relative to frozen out solution in space in accordance with method of solution concentration.

EFFECT: simplification of technological process of obtaining concentrated solution and reduction of concentrated solution loss, as well as exclusion of dendrite formation.
