How is distillation used for cannabis oil?
Multiple passes can be necessary especially if a company does not use a winterization process on their products . Winterization removes any contaminants like fats, and waxes from the initial oil extraction. Without this process those contaminants are left in the solution and will need to be removed during distillation to produce a pure final product. Setting up multiple distillation equipment that are connected directly to each other reduces the need for multiple passes through a singular system.
A similar equipment is the wiped film distillation system. The only difference to the above system is the introduction of a wiper blade that spreads a layer of the initial feed product onto the chamber walls. This thin layer reduces the amount of time heat is applied to the product. Prolonged exposure to heat can degrade a cannabis product and this equipment reduces that risk. The wipers also provide an even spread that supports more consistent evaporation and condensation rates.
As short path distillation requires less pressure to be exerted on the distillate, it is more common and favorable when working with volatile compounds and when purifying small amounts of substance. With heat, pressure, and humidity – it forces the remaining impurities and traces of solvent extraction residue out.
Simple distillation is appropriate for the separation of materials that have significantly different boiling points. When heated the liquid that is more volatile will vaporize and travel through the system, recondensing into a liquid when it passes through a chilled condenser. This results in the volatile substance becoming separated from the initial product.
I addressed the safety question in the first part of the answer, in the second part I’ll address the efficiency question: What is the most effective way to extract CBD-rich oil?
What are the safest and the most effective ways to extract and produce CBD oil? CO2, oil, or ethanol?
Short Path Distillation equipment
Hemp and cannabis oil extraction processes and techniques.
To further refine the CBD extract, and to isolate the CBD, the oil goes through Short Path Distillation. This works in much the same way as Winterization in that the extract is heated and each compound is then separated because each one has a different boiling point. In this way, each compound is isolated and can be used by itself.
CBD (Cannabidiol) is a compound that has shown promise in a variety of medical applications, like relief from pain and anxiety which are most common, along with many other ailments. A major benefit to CBD is that it doesn’t contain THC, which is the compound that makes users high, so this makes CBD an ideal product for children. Below you will find a step by step outline of how cbd oil is made.
