product description
The function of the monoethanol falling film evaporator is to separate the ethanol from the feed liquid and condense and recover the extract after the decompression vacuum evaporation. In the condenser, the boiling point of ethanol is lowered and it is easy to evaporate. Evaporation is easy to carry out, especially under vacuum and reduced pressure. Therefore, the evaporation area is reduced, and the condensation and recovery of alcohol vapor is difficult, so the heat exchange area of the condenser is increased. In order to obtain a good cooling effect, two-stage or multi-stage cooling and recovery are often used, which is also different from general aqueous solution evaporation.
Principle of Falling Film Evaporation
The material liquid is evenly distributed into each falling film tube through the distributor, and flows down the pipe wall in a liquid film state. Under the action of gravity and secondary steam flow, the material liquid flows down while evaporating, and reaches the falling film. At the lower end of the pipe, the material liquid and the secondary steam are basically separated and reach the separation chamber to achieve complete separation.
Product advantages
Low evaporation temperature;
Fast evaporation rate;
The material liquid residence time is short;
It can realize continuous feeding and continuous discharging;
Suitable for heat-sensitive materials;
Low energy consumption.
Application scope
Single-effect falling film evaporators are widely used in food, dairy, chemical, pharmaceutical, bioengineering, environmental protection engineering and corn deep processing, such as water solution, organic solvent solution, fruit and vegetable juice, milk, eggs, vitamin C, collagen , The evaporation and concentration of tea infusion, sodium glutamate, etc. is especially suitable for the evaporation and concentration of heat-sensitive materials. The beneficial elements of the materials can be protected to the greatest extent during the heating and evaporation process.
