摘要：
In a freeze-concentrating apparatus, an aqueous solution is cooled by a cooling cylinder 22 serving as a heat exchanger for cooling to continuously produce a suspension containing ice crystals. A liquid component is separated and discharged from the suspension to increase the ratio of the ice crystals, and the ice crystals are grown to produce a column-shaped ice cake. The ice cake is cut into an ice pillar of a given length and a concentrated solution is taken out from the ice pillar.
