乙酸乙酯用于茶多酚浸渍提取,完成浸渍提取后需要把其蒸发、冷凝、回收返回至储罐内储存以备再利用。而用于乙酸乙酯蒸发的单效降膜式蒸发器不同于其它水溶性物料的蒸发,均随其物理及化学性质的不同而发生了根本性的变化,不能按常规的降膜式蒸发器设计,尤其冷凝器的设计更是关键。 Ethyl acetate is used for extraction of tea polyphenols. After dipping and extracting, it needs to be evaporated, condensed and recycled back to the storage tank for re-use. The single-effect falling film evaporator for ethyl acetate evaporation is different from the evaporation of other water-soluble materials, both with the physical and chemical properties of the fundamental changes have taken place, not according to the conventional falling-film evaporator Design, especially the condenser design is the key.
