Cannabis Distillation Equipment
Molecular distillation equipment or short path distillation equipment is very efficient for cannabis distillation. At Lab1st, we offer you the Falling Film Evaporator for producers of high grade CBD and THC concentrates for dab, shatter, hemp, cannabis and other forms.
Material is delivered from a feed flask into a columniform evaporation section, getting heating, on the outside, (circulating hot fluid jacket type), and a slotted wiper mechanism forcing liquid around and downward in a thin film on the inside. In the center of the body is a wiped film evaporator with internal cooling condenser, providing a short path for vapor molecules traveling from the heated surface to the condenser surface. For cannabinoids, the internal condenser fluid must be kept elevated (~80°C) to prevent high viscosity or freeze up of THC, CBD and related components. During the itinerary downward, lighter (lower boiling point) fractions of the liquid begin to vaporize, move to the internal condenser and condense, falling down as a liquid into a vessel that catches and separates the distilled liquid (cannabinoid) which flows into a receiver flask. Heavier residue material (Chlorophyll, salts, sugars, heavy wax fractions) does not evaporate and instead travels through the still body and flows into a different receiver flask.

How Molecular Distillation Works
Molecular distillation is a special kind of liquid – liquid separation technology. It is different from steam distillation, which relies on the separation principle of difference of boiling point. While Molecular distillation relies on the difference of the average free path of molecular movement of different substances to achieve separation.
Under ideal condition, getting the liquid mixture flowing through the heating plate to heat, light and heavy molecules will escape from liquid level, and enter into the gas phase. Due to the light and heavy molecular free path is different, after different material molecules escape from the liquid level, their moving distance is different. If set up a cold condenser plate properly, then light molecules reach condensation plate be condensing exhaust, and heavy molecules can’t reach condensation plate, the exhaust along with the mixture liquid. In this way, the purpose of material separation is achieved.
