We have made freeze-concentration equipment consisting of an ice-making part, which continuously produces ice flakes on a rotating cooling drum, and a continuous centrifuge separating part. The purpose of this study was to evaluate the effect of shortening the residence time of ice flakes in the centrifuge part. Experiments using sea-water (Cl<sup>−</sup> concentration of the mother liquor 2.04–3.02 wt%) in this equipment led to the following results. The solute recovery rate and the treated quantity of mother liquor in tests with shortened residence time(15 s) compared favorably with those of previous tests with residence time of 60 s. In the previous tests, the solute recovery rate was 0.31–0.40 when the treated quantity of mother liquor ranged from 29.9 to 32.9 kg/h. The present tests gave a solute recovery rate of 0.54–0.73 for a treated quantity of mother liquor from 56.4 to 61.1 kg/h."},{"@language":"ja","@value":"溶液の凍結濃縮の装置においては，断続的運転が可能で，操作の単純な装置のニーズが非常に多い．左記ニーズ対応のためのドラム型連続氷片生成機および濾過型連続遠心分離機からなる連続凍結濃縮の装置を試作した．本報告では，本装置の遠心分離機氷片滞留時間の短縮化により溶質回収率および原液処理量が改善された以下のことについて記す．本報告試験の遠心分離機内における氷片の滞留時間は，前報の60
