技术介绍
目前,在海洋捕捞冰鲜工艺、海鲜加工、蔬果或冷冻肉类食物的加工工艺中都会多 次用到一种速冻的保鲜处理方法,该工艺是把待加工产品在水中浸泡一下,然后放到超低 温环境进行速冻,从而使产品表面形成一冰层,以此来达到保鲜的目的,在考虑到效能的情 况下,浸泡用的水采用零度或零度以下的水。而这种水的来源有三种方式一种是直接采用 冰溶解而得到;第二种是采用几十吨的盐水槽装置,槽里面同时放置几十吨不等的水箱,在 使用时,利用盐水的防冻性能,通过一制冷循环系统使盐水温度降低到-20度左右,随后通 过盐水与水箱的热量交换使水箱中的温度降到零度左右,该装置目前广泛应用于海鲜速冻 行业或大型生菜制造商场当中,该方法相比直接利用冰融化的方式有了很大的进步,但热 量交换的能效依旧不高,装置的体积大,制造成本高,很难得到广泛的应用;第三种是利用 国标蒸发器进行制冷,其大致结构参见图5:包括一壳90,壳体90 —端设置有用隔板隔开 的制冷介质进液腔和制冷介质回气腔,在壳体90的另一端设置有制冷介质回流腔,在进 ...
