    摘要:

    使用篮式离心过滤机对悬浮结晶冷冻浓缩技术产生的多孔性冰晶堆积床和浓缩果汁进行全床离心过滤。结果表明,经三级冷冻浓缩和三级离心分离后,苹果汁可溶性固形物含量从最初的10.2 ?SymbolpB@Bx逐级增加至19.6,28.5,40.3 ?SymbolpB@Bx;最终可溶性固形物得率为93.6%。离心过滤数学模型中的冰晶堆积床的渗透率和渗透系数分别为4×10-8 m2和0.16 m/s;滤布的过滤阻力为1.01×108 m-1,滤饼比阻为4.10×104 m/kg,相较块结晶技术所得冰晶的过滤阻力降低了至少一个数量级。该技术可用于冰晶与浓缩液作分离提纯。

    Abstract:

    A basket-centrifuge was used to perform a full-bed filtration of the porous packed ice bed and concentrated fruit juice produced by suspension freeze concentration (FC). The analysis of the experimental results showed that the apple juice concentration was increased from the initial 10.2 ?SymbolpB@Bx to 19.6, 28.5 and 40.3 ?SymbolpB@Bx, after three passes of FC and three passes of centrifugal separation. The final recovery yield of soluble solids of the concentrated fruit juice was 93.6%, and the permeability and its coefficient of the ice bed in the centrifugal filtration mathematical model were 4×10-8 m2 and 0.16 m/s, respectively. The resistance of the filter cloth was 1.01×108 m-1, and the specific resistance of the ice cake was 4.10×104 m/kg, one order lower in magnitude than that of the reported block FC. 4. This technique could be used for the separation and purification of ice crystals and concentrated liquid.
