Agitated Wiped Film Evaporator is best suitable for heat sensitive product where product drying time and drying temperature are very critical and well acknowledged among the buyers for its qualitative features. Our Agitated Wiped Film Evaporator is used for drying, vacuum distilling and many more. We are counted as one of the leading Manufacturers and Exporters of Agitated Wiped Film Evaporator. Able Engineering’s Agitated Wiped 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 vaporize component (distillate) or the concentrated component may be the product. Able Engineering provides turnkey solution for Herbal & Solvent extraction plant and phyto extraction and phyto chemical plants.
Agitated Wiped Film Evaporator Advantages :

How Agitated Wiped Film Evaporator Works : The Product to be treated is continuously fed into the Agitated Wiped Film Evaporator above the heating jacket and is spread on to the periphery by the distribution ring. The product is then picked up by the rotor blades and immediately formed in to a thin turbulent film on the heat transfer surface. The volatile components of the feed stock are therefore very quickly evaporated and flow counter-currently with reference to the feed, up towards the top of the evaporator to the rotating separator. Here, entrained droplets or foam are knocked out of the vapor steam and return to the evaporation zone. The evaporated components (low boilers) then flow out of the evaporator in to the condensation stage, column or to another downstream process step. For special applications co-current vapor/product flow can be used in which case 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 vapor outlet nozzle.
