Centrifugal Molecular Still

A mathematical model of the centrifugal molecular still has been derived based on a fully developed profile, but negligible normal and tangential velocity components. Thermal gradients, film thicknesses, and evaporation rates calculated from this mathematical expression correlate well with reported literative values as well as with the present ...

Experiments were carried out using a centrifugal molecular distillation unit with an evaporator temperature (EVT) from 60 to 120 C and a feed flow rate (Q) from 1.5 to 4.5 mLmin–1.

In fact, centrifugal molecular distillation (or short-path distillation) is recognized as the optimal thermal separation method for heat-sensitive materials like cannabis, because it poses minimal risk of damaging or destroying the product. Myers Vacuum is simply the recognized leader in centrifugal molecular distillation.

Jan 01, 1979 A CMS-5 centrifugal molecular still was operated with a 50/50 EHP-EHS test mixture over a range of feed and take-off rates. Efficiency of separation w…

May 13, 2021 Figure: Centrifugal molecular still. The feed is introduced into the center of a bucket-shaped vessel (1 to 1.5 m in diameter) that rotates at high speed (by centrifugal action). The film of liquid that is formed moves outwards over the surface of the vessel to the residue-collection pipe. The vessel is heated by radiant heaters.

Molecular distillation technology is used for the purification of natural health products, functional oils, etc., to get rid of the constraints of chemical treatment and maintain pure natural characteristics. Molecular distillation equipment includes fractionation towers with wiped film distillation units, centrifugal molecular distillation ...

Reconstitution of the distillation products indicates that cracking does not occur at temperatures up to 300 C. Comparison of the results obtained with the molecular still and with a high-vacuum pot still shows that there is good agreement between the property /yield relationships for the two units to the stage where thermal cracking commences ...

Sep 23, 2010 Centrifugal compressors act by increasing the kinetic energy of the fluid and then converting to static pressure. It produces an increase in head. Usually, the process requires a flow and pressure. The pressure relates to head through its density, which relates to mole weight. How much power (size) is required depends upon this.
