Rising film is suitable for the concentration of materials with lower viscosity, and falling film is suitable for the concentration of materials with higher viscosity. At the same time, both require higher equipment height. However, when the viscosity of the material changes greatly with the concentration, a single rising film evaporator and falling film evaporator cannot meet the demand. For this reason, a rising and falling film integrated evaporator is proposed. Utility Model Content
