Apr 27, 2022 This work describes the stripping and refining of cannabidiol (CBD) from hemp extracts using a wiped-film molecular distillation (WFMD) system. The process takes place in two stages, where the CBD gets stripped in the first stage and refined in the second stage. The main feed encompassing decarboxylated hemp extracts enters the stripping step at a CBD …

May 13, 2021 Working of Molecular Distillation: The vessel walls are heated suitably by a heating jacket. The feed flows down the walls and is spread to a film by the polytetrafluoroethylene (PTFE) wipers which move about 3 m/s giving a film velocity of about 5 ms. Due to heat liquid film evaporates and vapors hit the condenser.

Molecular distillation is a technology made exclusively for liquid-liquid separation. While traditional distillation does so with the boiling point difference separation principle, this method separates substances at the molecular level. This allows for a safer and purer technique of distillation. This method also produces a shorter residence ...

Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below, which is performed using a molecular still.It is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for example vitamins and polyunsaturated fatty acids.

Molecular distillation lowers the boiling point of liquids in a molecular still and is used to separate and remove undesirable molecules such as colorants, or to concentrate heat-sensitive molecules such as fatty acids. Molecular distillation also eliminates the low-boiling, ‘dirty’ top notes, resulting in a refined, super suave aroma.

Molecular distillation occurs at low temperatures and reduces the problem of thermal decomposition. High vacuum also eliminates oxidation that might occur in the presence of air. The rate of evaporation is controlled by the rate at which the molecules escape from the free surface of the liquid and condense on the condenser. The effects of feed ...

Molecular distillation was studied for the separation of tocopherols from soya sludge, both experimentally and by simulation, under different operating conditions, with good agreement. Evaporator temperatures varied from 100C to 160C and feed flow rates ranged from 0.1 to 0.8 kg/h. The process pressure was maintained at 10 −6 bar, the ...

Pope Wiped-Film Molecular Stills are a special type of short-path distillation equipment. These are continuous mode systems, as opposed to simple batch mode boiling flask stills (the latter often referred to as “short-paths”, though ironically, these are not truly short path designs as discussed in the next paragraph).
