摘　　要：介绍了一种基于界面渐进原理的新型连续式冷冻浓缩装置。该装置通过将制冷过程和浓缩过程有机结合,具有结构简单、调控性强、适用料液广、能源效率高等优点。初步分析表明该装置从料液中除去1t水的电能消耗低于5kW·h,在果蔬汁浓缩、海水淡化等领域均具较强的市场竞争力。A novel continuous freeze concentration installation hased on progressive freze concentration method is introduced. By the natural combination of refrigeration process and concentration process, the installation is simple, easily controlled, energy efficient, and suitable for a great range of liquid materials. A primary analysis shows that no more than 5 kW · h eleetrical energy is needed to remove 1 ton of water froro liquid materials. This makes it very competent for concentrating fruit and vegetable juices or making fresh water from seawater.
