| 摘 要： | 针对鲜浒苔含水量高、难以干燥的难题,采用离心脱水和带式干燥机相结合的方式尝试解决。通过测试离心机的脱水效率和能耗,计算带式干燥机获取热空气的3种方法（电热器、热泵、热风炉）的系统能耗,在综合分析其经济性的基础上确定了鲜浒苔的脱水干燥工艺。鲜浒苔经20 min的离心脱水,送入带式干燥机,由烟气余热回收或者热泵方式获取的热风干燥48 min是最优组合。该工艺条件获得的干浒苔水分含量为5%,盐分3.5%左右（以干基计）,此时系统运行的总能耗最低,经济性佳,产品质量好,是比较理想的鲜浒苔脱水干燥工艺。

| Abstract: | The drying process of Enteromorpha prolifra is studied and analyzed in this paper.Centrifuge is firstly applied for dewatering and desalting,and then belt drier is used to deeply dewater.Water content in the Enteromorpha prolifra was measured under different centrifugal working times,the energy cost and the economic analysis were compared for the three designed crafts: one method to obtain hot air used in belt drier is the electrical heating;the second method is by heat pump and the third one is by the hot-... |
