<p>A freeze-concentrating apparatus for cooling an aqueous solution with a cooling cylinder (22) serving as a heat exchanger for cooling and continuously producing a suspension containing particles of ice crystals. The liquid component is separated from the suspension and discharged to bring the particles of ice crystals into a high-density state, and the particles of ice crystals are grown to produce a block of ice particles in a pillar shape. The block of ice particles is cut into ice pillars of a prescribed length, and a concentrated solution is withdrawn from the ice pillars.</p> |
