wiped thin film evaporator
The wiped thin film evaporator is a highly efficient piece of equipment used in the process industry for the concentration of solutions and recovery of solvents. Its main function is to evaporate the liquid feed at a controlled rate, converting it into a concentrated product and vapor. The evaporator achieves this through a rotating wiper that spreads the liquid feed into a thin film on the heating surface, enhancing heat transfer and enabling rapid evaporation. Technological features include a heated vertical cylinder, a scraping mechanism to prevent fouling, and variable speed control for process optimization. Applications range from the food and pharmaceutical industries to petrochemical processing, where gentle handling of heat-sensitive materials is crucial.
