工作原理Working principle：

料液中的部分溶劑在真空作用下汽化并不斷排除，往復多次，料液里的溶劑不斷被蒸發掉，濃度得以提高，直到濃縮到所需的比重后由出液(膏)口出液(膏)。

Part of the solvent in the material liquid is vaporized and continuously discharged under the action of vacuum. and after several repetitions, the solvent in the liquid is continuously evaporated and the concentration is increased until it is concentrated to the required specific proportion and then discharged from the liquid (paste) outlet.

產品優勢Product advantages：

*WYZ普通型，用于水溶液的蒸發；

*WYZ general type equipment is used for evaporation of aqueous solution;

*WZYH酒精回收型，用于酒精溶液的蒸發，較大的冷凝冷卻面積，確保酒精回收，回收濃度達到70%-85%,酒精損耗率＜5%,酒精回收后溫度小于40℃；

*WZYH alcohol recovery type equipment is used for evaporation of alcohol solution. It has a large condensing and cooling area, ensuring alcohol recovery. The recovery concentration reaches 70%-85%, the alcohol loss rate is less than 5%. The temperature after alcohol recovery is less than 40℃.

*WZYS收膏型，用于單效蒸發和收濃膏，在單效正常蒸發后，關閉加熱室與蒸發室連接噴管和循環管的閥門，將料液全部進入蒸發室，通過蒸發室的夾套直接加熱， 進行減壓濃縮，提高物料的濃縮比重至 1.35-1.45。

*WZYS paste collecting type equipment is used for single-effect evaporation and concentrated paste collection. After single-effect normal evaporation, valves of the nozzle and circulating pipe connecting the heating chamber and the evaporation chamber are closed. All material liquid comes into the evaporation chamber, and is heated directly the jacket of the evaporation chamber, and is concentrated under reduced pressure until the concentration proportion of the material is increased to 1.35-1.45.
