How to make cbd isolate crystals

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’).

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.

Depending on what end product you’re trying to make you may prefer to use a CBD isolate powder when manufacturing lotions, edibles, beverages, etc. In order to make a powder you are simply taking the CBD isolate crystals and grinding them down into a powder-like substance.

Step 4: Decarboxylation

An additional option that some manufacturers complete to change the structure of the CBD isolate is to subject it to a crystallization process. This process results in a final product that is still 99.9% CBD but has a crystalline structure.

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.

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 1: Extraction

This crystallization process is started by putting the CBD oil into a large vat, or reactionary vessel, with a stirring attachment. The mixture is heated while constantly being stirred. Then, the temperature is lowered and the rate of stirring is slowed down. Once the mixture has cooled and nucleation starts to occur (the initial stages of crystallization), the stirring rate is drastically increased, which causes the crystals to separate from the solution. After this, the crystals are rinsed with pentane, or another chemical solvent, to remove any remaining unwanted impurities.

Making CBD isolate requires more steps than creating a CBD oil, as you have to remove every other element, such as phospholipids and flavors, from the product. While the process is more complex and requires additional equipment, it creates a totally pure end product that is free of anything besides CBD.

The second type of machine that we produce is a high-performance liquid chromatography machine. The high-performance liquid chromatography equipment uses a stationary phase that is in the form of particles that are packed into a column. The sample is pumped over the column and a separation of THC and CBD takes place. We do not use a solvent gradient unless we are cleaning the column.

CBD Isolation Methods

CBD isolation from hemp is an important manufacturing process that is used to make CBD isolate, or CBD crystal. CBD isolate is a purified form of hemp and is derived from industrial hemp. CBD isolation can also take the form of broad spectrum distillate which is a distillate without any detectable THC.

How Does CBD Isolation Work?

Winterization happens when the hemp product is subjected to freezing or below-freezing temperatures to further separate the fats and waxes from the CBD oil. Once the fats and waxes solidify under the sub-zero temperatures, you are left with a mixture of solvent and cannabinoids that remain in liquid form.
