Once you have all of the necessary items, you’re ready to learn how to make CBD oil from isolate. Pure isolated CBD infuses seamlessly with most carrier oils creating a ready to use CBD tincture that works just as well as what you’ll find in the store. Although the carrier oil that you use is entirely up to you, we recommend coconut MCT oil or hemp seed oil because they work well with CBD product types.
Whether you’re a new CBD user or known as a hemp advocate by all of your friends, you still might not understand precisely what CBD isolate is. Even seasoned CBD users struggle to comprehend the intricacies of CBD isolate such as how to make CBD isolate, and how it compares to other isolates.
How to Make CBD Oil from Isolate: The Benefits
2. Crude to Distillate: Crude hemp oil is further refined through a secondary extraction process that filters out most of the other plant materials resulting in a distillate containing 80-90% purified CBD. This method is sometimes referred to as winterization.
Do you want to know the best part of learning how to make your own CBD oil?
CBD is so popular as a pure isolate because isolates have a much broader range of use, including the ability to make CBD oil from isolate. Making your own CBD Oil is easier than you’d expect, and with a pure isolate, you are already halfway there.
3. Distillate to Isolates: Finally, CBD distillate undergoes an isolation process, which results in pure CBD. This is known as Chromatography, a repeated process until the only thing that remains is pure CBD.
While under vacuum, the extract is loaded into the feed tank where it passes over a heated rotating plate. From there, the heated oil then enters a secondary vessel where there are spinning wipers and a thin film is created around the heated, jacketed vessel. A long condensing coil in the middle of the vessel, cooled with recirculating fluid, recondenses the vapors back into liquid form. Receiving vessels then collect the CBD (known as ‘main body’) from the terpenes, volatiles and high boiling point cannabinoids (known as ‘heads’ and ‘tails’).
Once winterization has been completed it is necessary to now quickly filter those fats and waxes we coagulated from the miscella. A filter press is used with the assistance of a vacuum pump to pull the miscella mixture through a series of filter plates. Fats, waxes, etc are collected in one vessel and the desired miscella in another.
CBD isolate is 99% pure CBD, often in the form of a white powder that can be mixed into drinks or taken sublingually. This option is often popular among people who are just beginning to explore the use of cannabis or hemp derived products or looking to avoid the euphoric high associated with THC. It is also a great option for people who want hyper-accurate doses of CBD and the flexibility to create their own customized mixtures in their preferred carrier oil or liquid.
Step 4: Decarboxylation
To make any concentrate you first have to extract. Manufacturers can use either a hydrocarbon solvent, like butane or propane, or ethanol solvent. Typically, we see ethanol used for the production of CBD isolate often with the use of a larger commercial extraction system – like a centrifuge. Smaller extraction systems can be used, it just depends on your throughput goals.
Now that our extract has been winterized, filtered and decarbed, we can perform distillation. There are short path and wiped film distillation apparatuses on the market, for the sake of this article we will use wiped film distillation.
Winterization is the process of removing the fats, waxes and chlorophyll from the extract. Not removing these will lower the percentage and purity of the targeted CBD compound we are trying to capture. To achieve winterization you are essentially cooling down the extract to sub-zero temperatures with a solvent. Then, maintaining that chilled environment for a period of time in order for the lipids (fats and waxes) to coagulate and separate from the crude oil – now termed ‘miscella’.
In order to achieve optimal CBD content, decarboxylation is a critical step prior to distillation. The process of decarboxylation is to remove carboxylic acid and CO2 from cannabinoids present in the cannabis extract. Converting the acidic cannabinoid (CBDa) to its neutral form (CBD) ensures the end product contains all of the several benefits the cannabinoid has to offer. Furthermore, failure to remove CO2 from the extract will also affect the ability to properly form a vacuum in your distillation apparatus. The decarboxylation process is achieved through the application of heat in a reactionary vessel.
Due to the high level of processing, CBD isolate is not considered organic nor can it be certified organic. However, broad spectrum distillate can certainly be made organically and labeled organic.
extraktLAB produces several different kinds of CBD crystal isolate production machines. The first kind of machine is an assembly of stirred, jacketed glass reactors and pumps that are assembled into an automated machine.
CBD isolation methods define the equipment, the solvent or combination of solvents to be used for extraction. Isolation methods also define critical method variables such as:
CBD Crystals as a Method for Sample Preparation
The next step in the process is to concentrate the matrix by removing the solvent so that it can be injected on the chromatography column. The chromatography in this case is tuned to remove THC from the remaining CBD that is left in the supernatant.
This equipment includes grinders, dryers, extractors, filtration equipment, distillation machines, falling film evaporators, and of course, chromatography equipment.
The first technique is chromatography which separates out the CBD from the THC while maintaining the phytonutrients, terpenes, pigments, and natural plant components that are thought to contribute to the “Entourage Effect.”
These standards are collectively known as good manufacturing practices (GMP) or good production practices (GPP) and are administered by the Food and Drug Administration through an inspection program.
