But how much does a short path distillation system cost?
Lastly, these machines are easy to use and are largely automated in their function.
However, a growing body of scientific research has found that full-spectrum extracts have many benefits over isolates. The myriad of compounds found in cannabis work together to form what’s known as the entourage effect, which enhances the effectiveness of the medicinal properties.
Benefits of Short Path Distillation
High evaporation rates allow for more distillates to be captured while the relatively low processing temperatures (130-180°C) contribute to the fact that there aren’t any solvents needed to move the extract material through the process.
The close proximity of the condenser to the heated vessel wall provides a short path for the extract to travel to. Hence the name, short path distillation process. As the wiper system moves the extraction material down through the vessel, it evaporates to the condenser which converts it back to a liquid. This liquid is then collected at the bottom and is now a distillate.
Most importantly, this system will separate cannabis into high concentrations of THC and CBD distillates. In fact, short path distillation can result in cannabis distillates that are 99% pure. So if you are trying to make a pure CBD product, for example, going with the short path distillation process is one of the best methods you can use.
Where other extraction processes use heated beakers, continuous feed also allows for a greater degree of scalability to your production which just isn’t much of an option with batch mode stills.
Product consistency is fundamental to building and maintaining any successful brand.
In order to further purify the oil, it will be subject to the distillation process with a specialized commercial distillation unit. The distillation process isolates specific compounds, such as THC and CBD, thereby producing a refined cannabis oil (or “distillate”) with an over 90% purity of CBD and THC.
Building Better Brands by Isolating THC and CBD
In order to produce a consistent product, the THC and CBD cannabinoids must be isolated and separated from the other cannabis components and then infused into the product. By using the process of distillation, this is possible.
Imagine if your favorite beer tasted and smelled different every time you drank it. Or the alcohol content was wildly different with every batch. Faced with such unpredictability, it wouldn’t be your favorite brand for long.
A simple example of distillation is the process of purifying water. Heating water to 100°C (212°F) will vaporize the H20 molecule, leaving behind any undesirable compounds. Rapidly cooling this water vapor causes it to re-condense into distilled, purified water.
Types of CBD Distillation equipment
Basically, a container with water is put on a burner. It will have an outlet that feeds into a plant material flask. The plant material flask will have an inlet and an outlet. As the steam rises from the container through the plant material, essential oil vapors are released. These essential oil vapors are collected in a condenser tube that condenses the vapors into a hydrosol. This hydrosol is a mixture of water and essential oil. Further work is done to separate the oil from the hydrosol.
Note this can be problematic when marketing, distributing and shipping this product, so CBD distillate is often diluted with ethanol, MCT or glycerol to keep the total THC under 0.3% and ensure compliance with federal and other relevant regulatory limits.
CBD Distillation Equipment
CBD oil only contains tiny amounts of THC, the primary active ingredient in marijuana. This lack of THC means that CBD oil is non-psychotropic and non-psychoactive. So, to answer an often-wondered question: no, CBD will not make you feel “high.” CBD oil allows the user to dose cannabidiol and other cannabinoids, amino acids and terpenes that are found in medical marijuana — without the high associated with marijuana. CBD’s general effects are currently the subject of excitement and scrutiny in the scientific and medical worlds, as research on cannabidiol continues to evolve.
These three systems are very similar in concept. Falling film distillation is the basic version. Wiped film adds a wiper to increase surface area. Short path distillation improves performance by minimising the distance the CBD vapor travels before evaporation.
While Falling film Wiped film and short path distillation have similar mechanisms and uses, they each have benefits that make them more widely used for specific applications.
CBD Distillate is generally 80-90% or more CBD content and appears as a golden amber, highly viscous liquid. It crystallises readily, so normally appears as a white waxy or crystalline solid at room temperature.
