High-Quality MVR Evaporators for Efficient Evaporation

   The material liquid to be concentrated is pumped into the top of the heating tubes and flows downward along their walls as liquid film.
   In this process, the liquid film inside the tubes begins to boil and partially evaporate being heated from outside the tubes.
   The remaining liquid and vapor are further removed in subsequent separating machines.
   Reasonably determined material liquid flow prevents bottom section of tubes from getting excessively dry while ensuring optimal thickness of liquid film so that best heat exchange effect and minimum power consumption is achieved.
   Falling film evaporator is applicable to both cyclic evaporation and one-way evaporation processes.

   As raw material (liquid) circulates among heating and separation chambers at a high speed under the function of a circulating pump, it is heated up in the heating chamber and flashes in the separation chamber to achieve high-efficiency vapor-liquid separation.
   The flow rate in the heat exchange tube is high, which effectively improves the heat transfer efficiency.
   The evaporation process is conducted in the separator instead of heater.
   As a result, fouling caused by crystallization and precipitation of materials in the tubes is reduced.
   Forced circulation evaporator is especially suitable for materials that are easy to scale due to high viscosity.
