Short-path molecular distillation is a technique used to purify compounds, such as cannabinoids, through a thermal separation process, utilizing a deep vacuum to reduce the boiling point of the desirable components, fractioning substances based on their boiling points.
Wiped-film distillation utilizes wipers or rollers to spread the feed-stock into a thin film on the evaporator, which greatly increases the surface area and decreases the residence time (or how long the crude oil is exposed to high temperatures). By using an internal condenser, the distilled vapor travels a short path before condensing, enabling efficient operation with little waste and minimal thermal degradation. This entire process operates in a continuous manner to enable rapid, repeatable, and scalable production. With a low operating cost, high throughput, and unbeatable reliability, wiped-film distillation has become the most popular method of purifying crude extracts to produce high potency concentrates.
A necessary precursor for cannabinoid isolation, short-path molecular distillation is the preferred technology utilized during the production of CBD and CBG isolates.
