METHOD AND DEVICE FOR CONTINUOUS CRYSTALLIZATION OF LIQUID BY FREEZING Russian patent published in 2006 - IPC B01D9/02 

Abstract RU 2278717 C2

FIELD: solidification.

SUBSTANCE: device comprises mixer and crystallizer that has at least of one evaporator. The evaporator has outer pipe, inner pipe, and rotating member mounted in the inner pipe. The rotating device comprises rotating shaft and one scraper mounted on it. The angle between the inner side of the scraper and the diameter of the inner pipe should prevent the crystals to grow on the inner side of the evaporator. The method comprises mixing liquid with the gas and causing the mixture to flow through at least one evaporator for three-dimensional crystallization. The mixture flows through the inner pipe of the evaporator where it is set in rotation by means of rotating device.

EFFECT: reduced power consumption and enhanced efficiency.
