Falling Film Evaporators’ Material
Falling film evaporators are usually regarded as the high-efficiency evaporation equipment, especially suitable for heat sensitive material. Its evaporation system consists of evaporators, separators, condensers, hot press pumps, vacuum and drainage systems,various utility liquid transfer pumps, operating systems, electrical instryment control cabinets,valves, pipelines and other systems. The main reason why falling film evaporators are especially suitable for heat sensitive material can owes to the material. Falling film evaporators are mainly made of titanium alloy and various stainless steel such as SUS3045, 3166L and Q2335B.
Classifications of Falling Film Evaporators
There are several kinds of falling film evaporators: single effect of falling film evaporator, double effect of falling film evaporator, three effect of falling film evaporator, four effect of falling film evaporator, five effect of falling film evaporator, six effect of falling film evaporator. It is suitable for milk, glucose, xylose, pharmaceutical, chemical, bioengineering, environmental protection engineering Low-temperature concentration in industries such as waste liquid recovery.
Characteristics of Falling Film Evaporators
The characteristics of falling film evaporators are as follows:
1. Since the solution flows in a single-pass type evaporator, the heat transfer coefficient is high, the residence time is short, and the material is not easily deteriorated. It is suitable for processing heat sensitive materials.
2. The liquid of the falling film evaporator is added from the top of the evaporator, and descends along the wall of the tube under the action of gravity. Sample will be evaporated and concentrated during this process, and a concentrated liquid is obtained at the bottom. The falling film evaporator can evaporate materials with higher concentration and higher viscosity.
3. Falling film evaporator is suitable for evaporation and concentration of foaming materials.
