Cryogenic Fractional Distillation Column / High Vacuum Plate Distillation Column

50L - 100L Reboiler Fractional Distillation Column for CBD / THC / Hemp oil

——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.

Fractional distillation column is a fractionating column used for the separation of miscible liquids. It is a long glass tube with wide bore. It either filled with glass beads, small stones, porcelain rings or coke. It can also be blown in to a shape with several spheres or pear bulbs. The purpose of the glass beads is that they improve the distillation process.

There can be several trays in the fractionating column in place of glass beads and bulbs. These trays are called theoretical plates. Theses trays or theoretical plates serve the purpose of the glass beads.

For commercial purpose fractionating column with hundredth of theoretical plates are used. The main aim of using the fractionating column is to increase the surface area for cooling of liquid and to provide hurdles to the rising vapours and descending liquid.
