摘要： Crystallization method and crystallization apparatus each use vertical plates for crystallization thereon. Both surfaces of the plate are used for different two liquids to flow down as films. Specifically, on one vertical surface, a feed liquid mixture containing crystallizable components therein flows down as a film, and on an opposite vertical surface, a cooling medium flows down as a film. Accordingly, the crystallizable component contained in the feed liquid mixture is cooled and crystallized to form crystal layers on the one vertical surface of the plate. The formed crystal layers are melted by a heating medium which flows down on the opposite vertical surface, and are collected as a melt. A pair of the plates may be used to form a unit to purify the liquid mixture on a large scale. A number of the units may be used to form a block which is suitable for a larger-scale crystallization processing. Further, a number of the blocks may be used to purify the liquid mixtures on a further larger-scale processing.
