Agitated Thin Film Evaporator
Agitated Thin Film Evaporator

Agitated Thin Film Evaporator is well-known among buyers for its high-quality features and is best suited for heat-sensitive products where drying time and temperature are critical. Our agitated thin film evaporator is for drying, vacuum distilling, and many more uses. We are counted as one of the leading manufacturers and exporters of agitated thin film evaporators. 

Able Engineering‘s agitated thin film evaporators quickly separate volatile from less volatile components using indirect heat transfer and mechanical agitation of a flowing product film under controlled conditions. Either the vaporised component (distillate) or the concentrated component may be the product. Able Engineering provides turnkey solutions for herbal extraction plants, phytoextraction plants, and phytochemical plants.

How Thin Film Evaporator Works: 

The product is continuously fed into the thin film evaporator above the heating jacket and spread onto the periphery of the distribution ring. The product was then picked up by the rotor blades and immediately formed into a thin turbulent film on the heat transfer surface. The volatile components of the feedstock very quickly evaporated and flowed counter-currently with reference to the feed, up towards the top of the evaporator and into the rotating separator. Here, entrained droplets or foam are knocked out of the vapour stream and return to the evaporation zone. The evaporated components then flow out of the evaporator into the condensation stage, column, or another downstream process step.

For special applications, co-current vapor/product flow is used, in which a separation vessel is fitted at the bottom of the evaporator below the rotor in place of the normal rotor-mounted separator and the upper vapour outlet nozzle.
