Alcohol Distillation Thin Film Evaporator Lab Scale Fractional Molecular Distillation

Thin Film Evaporator Lab Scale Quick Details

thin film evaporator is a new type of efficient evaporator, which is forced to form a film by rotating scraping plate for heat exchange according to the difference of boiling point of each component of the mixture, and rapidly passes through the heating surface for heat separation under vacuum conditions.The material is added to the evaporator from above the heating area;It is distributed to the heating surface of the evaporator through the liquid distributor, and then the material is continuously and uniformly distributed on the heating surface by the rotary scraper system, and pushed downward in a spiral shape.In this process, the light components are vaporized to form steam flow rise, after the vapor-liquid separator transferred to the external condenser condensation collection;The recombination is discharged from the bottom of the evaporator.

Thin Film Evaporator Lab Scale Introduction

——Operation
Feed liquid is admitted into still under high vacuum, immediately spread into a very thin film and forced quickly down the
evaporation surface. Heated walls and high vacuum drive the more volatile components (distillate) to the external condenser as the less volatile components (residue) continue down the cylinder. The resulting fractions, thus separated, exit through individual discharge outlets. Depending on application, the desired product is either the distillate or the residue fraction. Small amounts of condensable low MW compounds collect in cold trap upstream of vacuum system. For high solvent loads, an optional external condenser may be installed immediately downstream of the still.
 
——Particular features
Continuous distillation process.
Low operating pressures (100~10000Pa ,100Pa=1mbar).
Short residence time.
High evaporation rates.
Processing of high-boiling, high-viscosity or crystallizing products is possible.
Can be used as a reboiler for column.
Low fouling on evaporator wall.
——Fields of application
For separation of large quantities of components with high volatility.
For residue removal or decolorization.
For products with high-viscosity and easy to crytallizate.
For heat sensitive material
