Distillation separates components by their boiling points. This is commonly referred to as the “efficiency” of a distillation column. The more efficient a distillation column the better it is as separating components.

Spinning band distillation can produce distillate with very high THC/CBD concentrations. Over 90% THC concentration is typical for a first pass. Some customers are routinely producing 98%+ cannabinoid distillates!

The spinning band creates the highest amount of vapor-liquid contact by rotating the band at several thousand rpm inside the distillation column. The action of the spinning band forces the vapor into contact with the liquid on the surface of the distillation column, refreshing it with every rotation. The spinning band helix simultaneously pumps excess liquid into the boiling flask.

Contact between the ascending vapors and the descending condensate concentrates the lower boiling component in the vapor. More contact between liquid and vapor means a better separation.

Mono-terpenes have the lowest boiling points, so they are collected first. They can be found in the cold trap receiver due to their low boiling points.

Residual ethanol is collected next in the fraction collector followed by the higher boiling terpenes. Each of these can be collected in their own receiver by rotating the fraction collector to the next receiver.

Once all the terpenes are distilled the THC/CBD fraction will start to come over. This is the stuff you’ve been waiting for. The color of the THC distillate is strongly influenced by the extraction process and any post extraction treatments.

When the last of the THC/CBD is collected, the distillation is stopped. The boiling flask typically has less than 2% cannabinoids. Cannabinoid waste is kept to a bare minimum through the efficiency of spinning band distillation.
