heat transfer in thin film evaporator is very quick
and efficient, thus demanding lower surface area and
heat input as compared to other types of evaporator.
Due to high vacuum distillation and very short residence
time the thin film evaporator are suitable for handling
wide range of heat sensitive, high boiling and viscous
feeds. Due to low rotor speeds in the range of 100 to
150rpm, the horse power requirements are very low. To
reduce the pressure drop between the evaporator and
condenser, the internal condensers can be provided to
achieve short path distillation. The thin film evaporators
are designed to handle various products with operating
pressures up to O.1torr. Liquids with viscosities above
2,00,000cps can be handeled in these evaporators.
