How Wiped Film Distillation Equipment Works

Wiped film distillation is a special liquid-liquid separation technology, which is based on the difference of the average free range of molecular motion of each substance in the mixture to achieve separation. As long as the temperature difference between the hot and cold surfaces is sufficient, the separation can be carried out at any temperature, so the operating temperature is far below the boiling point of the material, and for the separation of high boiling point, heat-sensitive and perishable materials.Wiped film distillation is the best separation method.

The complete wiped film distillation equipment includes six parts: feed system, short path evaporator, heating system, cooling system, vacuum system, and discharge system.
Wiped film distillation equipment working process

1. The material is fed from the top of the evaporator, matched with a high-precision gear pump, to achieve continuous automatic feeding at a constant speed.

2. Start the rotating scraper to make it rotate at a constant speed, and the mixed liquid forms a very thin, turbulent liquid film on the inner wall.

When the material passes through the heating medium, due to the different free paths, the free path of the light molecules is greater than the distance from the heating surface to the condensation surface, and the overflowing light molecules reach the condenser to form liquid beads, flow down the wall of the condenser tube, and discharge through the bottom discharge pipe ;The free path of the heavy molecules is less than the distance from the heating surface to the condensation surface, and the heavy molecules are discharged along the inner wall of the heating medium through the side discharge pipe, so as to achieve the purpose of separation.
M olecular distillation equipment is different from traditional distillation. It can quickly separate materials without heating materials to boiling point. Therefore, the distillation temperature is much lower than traditional distillation temperature, which greatly shortens the contact time, which is beneficial to high boiling point, heat sensitivity and easy to use. Separation of oxide materials.
