The Wiped Film Distillation Equipment can be considered as a kind of distillation method operated under a high vacuum condition.

When the average free path of steam molecular is greater than the distance between the evaporation surface and the condensation surface, the liquid mixture can be separated by utilizing different evaporation rates of each component in the liquid mixture.

It is a kind of process of distilling and purifying the heat sensitive material or high boiling point material making use of the difference of material molecular movement free path in high vacuum degree.

And the Wiped Film Distillation Equipment is mainly used in chemical, pharmaceutical, petrochemical, spices, plastics, oil and other fields.

Actually, the Wiped Film Distillation Equipment is a special liquid-liquid separation technology, different from traditional distillation that relies on the difference in boiling points.

Main Features

1. The main body of the Wiped Film Distillation Equipment is made of high borosilicate glass 3.3, allowing the whole process to be observed very clearly.
2. The magnetic force transmission system can realize the seal property of whole machine. The transmission rod of the drive motor needn't go through the sealing surface of the distiller. The whole system possesses a good sealing performance. The minimum vacuum pressure is up to 0.001mbar.
3. The highest temperature of the system can reach 230℃/300℃. The accurate temperature control can be realized.
4. High evaporation efficiency and less retention time, with minimum time delay.
5. High-precision distillation barrel allows the liquid to form a complete and unified thin film on the heated surface. The smooth inner surface can avoid sticking and scaling.
6. The German brand variable-frequency reduction motor can operate safely and reliably. The self-cooling fan can work continuously for a long time.

Main Advantages

1. Thin distillate film and high heat transfer efficiency.
2. Low distillation temperature. The Wiped Film Distillation Equipment can be operated at the temperature that is far below the boiling point. The separation can be realized as long as there is a temperature difference.
3. High distillation vacuum degree. A high vacuum degree can be obtained inside the Wiped Film Distillation Equipment device, so the Wiped Film Distillation Equipment can be operated under a very low pressure. It's not easy for materials to oxidize and be damaged.
4. The pure and safe product can be obtained with simple operation process and less equipment. The Wiped Film Distillation Equipment can separate materials that can't be separated easily by the normal distillation.
