    Feature about Three Types of the Evaporator

         Do you know what the evaporator is? Of course, it is clear and obvious that the evaporator is often used to determinate the evaporation capacity of water in the atmosphere in a certain time interval. With beautiful appearance, compact structure and strong practicability, this kind of spiral plate heat exchanger is suitable for the profession of hydrometric station, meteorological observatory and other departments.
         A saying is like that “It takes all kinds to make a world.” Exactly, everyone has his own characteristic and the evaporator has various types with different feature in the same way. It is divided into three ones, such as single-effect evaporator, double-effect one and multiple-effect one. As for their own working feature about them, the simple explanations are going into the eyes following.
         Firstly, the single-effect evaporator is the most basic evaporator, which can directly send the secondary steam without use to the condenser to remove. On the one hand, the vacuum concentration is adopted to recycle the alcohol so that it can improve the productivity and enhance the recycling benefits. On the other hand, with the use of single-effect concentrator, the pharmaceuticals from the concentrator is strong without pollution, therefore, this evaporator is suitable for the material enrichment such as traditional Chinese medicine, western medicine, dairy products and so on.
         Secondly, for the double-effect evaporator, it is simple to say that the two single-effect ones connect in three forms, which is a kind of new evaporation and enrichment facility in vacuum with high efficiency and energy saving. The most main feature is multifunctional, such as feeding continuously or intermittently and recycling the high alcohol concentration. Also, the evaporation rate is large because of the evaporation way of natural circulation.
         Thirdly, the multi-function extracting tank should connect multiple evaporators so that the secondary steam is introduced to the next evaporator as the heating steam and is condensed to the distilled water. For the one, in the working process, it can reduce the steam consumption and improve the economy with the use of triple-effect evaporator and four-effect evaporator. For the other, it is selective to the flow with four types, so this kind is used widely than the others.
          To sum it up, each kind of evaporator plays an important and indispensable role in its own field with its own special feature and function. They take effect and work hard everyday and make everyone see them about their working abilities. Therefore, it is deeply believed that you should bring them into your working areas as long as you need them.
