Agitated thin film evaporator molecular distillation wiped film evaporator

Short path (molecular) distillation system is considered as the safest mode of separation and to purify the thermally unstable molecules & related compounds with low volatility & elevated boiling point. In the high vacuum environment, molecular distillation has the advantages of low distillation temperature, short heating time and rapid separation.

1. The control system of the vacuum unit reaches the required vacuum. 2. The temperature control unit control system reaches the required temperature. 3. Material feeds to the evaporation tower through gear pump. 4. The scraper in the evaporation tower rotates quickly to allow the material to form a thin film. The material liquid volatilizes under high vacuum and heating conditions. The molecular free path of light components is larger and is captured by the inner condenser, and the molecular free path of heavy components is smaller and falls back to the wall of the evaporation tower. 5. The light component flows down the inner condenser and is pumped out of the system by a gear pump or pumped to the next short-range. The heavy component flows down the wall of the evaporation tower and is pumped out of the system by a gear pump or pumped to the next short-range. 6. The ultralight components and residual solvents that have not been trapped by the inner condenser are trapped in the outer condenser and cold trap.
