Instrument Introduction
The main difference between thin film evaporator and short path distillation apparatus is the location of the condenser and the operation pressures.
In a thin film evaporator the raw material is heated up in the internal surface of a heated tube until the lower boiling component starts to evaporate. Then vapors are liquefied on the cold tubes of a condenser. In simple thin film evaporator design, the condenser is located outside the evaporator but as close to as possible. In a short path distillation apparatus the condenser is located inside the evaporator body.
Due to the different design details, conventional thin film evaporator can be used down to approx. 1 mbar, while short path distillation apparatus can be used down to 0.001 mbar. The thin film evaporator is suitable for the separation of large quantities of light volatile components, while the short path distillation apparatus is suitable for the separation of a heat-sensitive valuable product.
Product Advantage
¦ Small pressure losing
¦ High diathermanous coefficient, high evaporating efficiency
¦ Low evaporating temperature
¦ Short heating time
¦ Strong adaptability, easy to operate
Application Field
The thin film evaporator is used to evaporate, condense, decolor, trip, react, degas, deodorant the materials with high heating-sensitive and easy to oxidate. It is an excellent method for gently thermal treatment of heat sensitive, high boiling products. At present, there are hundreds of products used in thin film evaporator. The thin film evaporator is widely used in medical, pesticide, oil and fatty chemical industry, fine chemical industry, commodity chemical industry, biology chemical industry and so on.
