Shachi’s thin film evaporators are built for optimized processing of the feed, reduction of wastage and offer maximum flexibility in the evaporation process Single system can be used to process different products under variable operating conditions due to customized design.
Agitation of the flowing product film under controlled conditions
Agitated thin film evaporators are typically used for fluids which are difficult to handle due to higher sensitivity and viscosity. Such an evaporator consists of tow key components: a jacketed shell and a rotor which rotates at high speed inside the shell. The feed is inserted into the mechanism at the top. Then, is is distributed along the shell via a distributor. After this, the rotor works to spread the feed into a thin film and agitate it further. The liquid is distributed in the form of a thin film on the heated wall where the heat transfer takes place.
The rotor encapsulated inside the heating shell wipes the fluid film from the walls. Hence this type of evaporator is also called as Wiped Film Evaporator. The rotor also serves to stabilize the liquid film on the heated surface at high rates of evaporation. This makes evaporation in the area of nucleate boiling possible without causing a breakup of the film. It also prevents forming of a vapour layer with insulating effect under the liquid film. The working principal of agitated thin film evaporators enables businesses to extremely high specific evaporation rates.
The vapors generated after heating flow concurrently are cleaned using an entrainment separator. The turbulence helps the thorough heat transfer and mechanically ensures that the entire mass undergoes the process to produce high yields from 30% to 80% concentration possible in a single pass. Thin film evaporators avoid the deposition of products. Intensive mixing process within the unit also serves to protect temperature-sensitive products from overheatin
