The Wiped Film Distillation Equipment also known as the short-path distillation, plays an important role in the separation, purification and concentration of natural products. Different from the normal distillation, the Wiped Film Distillation Equipment is regarded as a special liquid-liquid separation technology.

This 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. The Wiped Film Distillation Equipment is mainly used in chemical, pharmaceutical, petrochemical, spices, plastics, oil and other fields. The Wiped Film Distillation Equipment can be done 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 making use of different evaporation rates of each component in the liquid mixture.

The Wiped Film Distillation Equipment has a high evaporation efficiency and less retention time, with minimum time delay. It can be seen that the glass parts are all made of high borosilicate glass, which is not only corrosion resistant, but also convenient to observe the whole process clearly.

Furthermore, it adopts the German brand variable-frequency reduction motor, with a safe and reliable operation. The self-cooling fan can work continuously for a long time. 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. During the operation of the Wiped Film Distillation Equipment , the highest temperature of the system can reach 230℃/300℃. The accurate temperature control can be realized.
