Difference between wiped film evaporator and falling film evaporator
Falling film evaporation
is to add the liquid material through the upper tube of the heating chamber of the falling film evaporator. Through the liquid distribution and film forming device, it is evenly distributed into the heat exchange tubes. Under the action of gravity and vacuum induction and air flow, it forms a uniform film top down flow.Wiped film evaporator
is a new type of high-efficiency evaporator which is through a rotary wiper to make a film, and has a high-speed flow, high heat transfer efficiency, short residence time. -
1. Compared with falling film evaporator, the wiped film
evaporator scrapes the material into a film by a motor, so the scraping film is more stable, the liquid film is more uniform, and the efficiency is higher than that of the falling film evaporator.The falling film material may be affected by various effects during the falling process, and the liquid film is not uniform, so the evaporation effect is not effective.Short heating time
2. The recovery rate is different, the recovery rate of the wiped film
is 95%, and the falling film is 80%.3. Wiped film evaporator
has his irreplaceable advantages: Small vacuum pressure drop | Low operating temperature | Short heating time | High evaporation rate | Large operational flexibility. -
So wiped film evaporator
is mainly used for evaporation concentration, desolvation, stripping, reaction, degassing, deodorization (gas) taste, etc. Contact [email protected]
