500 - 1500 ml / h Molecular Distillation Equipment for CBD / THC / Hemp oi l/ Cannabissativa

—— 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.

Different from the traditional wiped film evaporator design, the condenser is located inside the Molecular Distillation Equipment. There is no vapour line between evaporator and condenser. The considerably lower pressure in the Molecular Distillation Equipment is obtained by the short distance for the vapours on their way from the evaporator surface to the condenser. In addition, the cross section area of flow is equal to the evaporator surface, so that there is only a minor pressure drop between evaporator and condenser. The special design of Molecular Distillation Equipment allows operating pressures, also on industrial scale distillation systems, down to 0.001 mbar. The very low operating pressures ensure very low distillation temperatures and therefore a very gentle distillation is possible. The short path distillation allows the thermal separation of high molecular and high-boiling products at high yields and good product quality.

If the distance between evaporator and condenser is in the order of the average free path length of the molecules, this process is also called "molecular distillation".
