Cannabis manufacturers have recently discovered two unique distilling processes. Information you find through a simple online search may be false or misleading. Here are some facts about the distillation of cannabinoids to help put your mind at ease.
Purity and Uniqueness
Cannabis manufacturers use only the purist forms of cannabis. This allows for the distillation of extraordinarily clean and clear concentrates of THC and CBD for medical and recreational use. This is because reputable manufacturers have found two new processes: short path distillation and wiped film distillation. Both processes remove unwanted molecules while preserving a distillate with up to 99% of total cannabinoids.
Two Part Process
The continuous wiped film distillation process has two parts, known as cuts. In the first cut, terpenes are removed from the cannabinoids. In the second cut, lipids, impurities, and solvents are extracted.
Wiped film distillation machines use a continuous feed to send the extracted materials to a heated evaporation vessel, where a rotating blade distributes them onto walls for heating. The materials are then fall down to an evaporation surface. The heat will evaporate material that has lower boiling temperature. There is an internal condenser in the middle of distillation body. Internal condenser was set at temperature that lower than outer surface. Cold surface condense vapor into liquid that is collected at the bottom.
Short path distillation equipment comes with a heated flask through which the material is fed. Heat is gradually applied to the material within the flask, and a vacuum helps draw out vapors to a fractionating tube. The fractioned vapors then go to a condensing tube where each fraction follows a different path to the collection flask.
First cut will remove terpenes and solvent from the rest of material, and second cut will remove THC or CBD from the waste which has higher boiling temperature than cannabis content. THC becomes extremely thick and sticky (similar to honey), while CBD becomes crystallized. At this point in the process, typical methods require the use of solvents to bind with the cannabis extractions. Depending on the size of evaporator surface, wipe film distillation can process ranging from 1 Kg to 50 Kg of crude oil each hour. The distilled cannabis oil can be used for a variety of products, including vape cartridges and edibles.
The biggest advantage of using the wiped film distillation methods are the continuous feeds that come built into the machines. The feeds are better than the heated beakers used in traditional methods. Continuous feeds are excellent for making large batches of cannabinoid distillates for a longer amount of time and produce more consistent product. Plus, they provide better scalability than your typical Batch Mode still.
Another advantage to these innovative processes are the high evaporation rates, which help capture more distillates at low temperatures between 130 and 180 degrees. This helps significantly with the separation of multiple strains of cannabis into higher concentrations of THC and CBD. At higher concentrations cannabis oils and tinctures will have a smoother flavor, which creates a better overall experience for customers.
