Large Scale Thin Film Evaporator Distiller For CBD Crude Oil Wiper Basket
Thin Film Evaporator Introduction
A highly efficient device for evaporation and distillation that uses scraper system to force the liquid film forming. It features high heat transfer efficiency, fast evaporation speed and short material residence time.
It consists of one or more cylinders with a heating jacket and a scraper rotating inside the cylinder. The wiper continuously scrapes the feed on the heated surface into a uniform thickness liquid film and moves it downwards. During this process, the low-boiling components are evaporated and the residue is discharged from the bottom of the evaporator.
Thin film evaporator is used in pharmaceutical, food, petrochemical, environmental protection., etc.

The Thin Film Evaporator is used for concentration, distilling, stripping, dehydration and deodorisation of products which are heat sensitive or viscous. The equipment can handle a very wide range of feed compositions ranging from 1% to over 95% concentration. Thin Film Evaporator has several advantages as stated in the table below. The operation is continuous with a single pass; the self cleaning continuous contact wipers produce and renew the thin film. Such an operation improves product yield, avoids residue and colour formation. It has an internal condenser (optional) that minimizes the pressure drop and maintains vacuum.
