Once the extraction process is complete a processor is left with “crude extract” that is 55-75% cannabinoid and that may in some instances, be sold without any further processing. For the majority of processors however, further separation of the remaining elements is necessary to obtain fully purified, high value CBD/THC oil.

The next step in the purification process is to remove waxes by cooling the extract down to approximately -20°C (-4°F) in a chiller-driven jacketed vessel. This “winterization” process precipitates some of the undesired elements out of the solution which after filtering, leaves oil made up of cannabinoids, chlorophyll and terpenes. Decarboxylation is an important step that may be performed either before or after the winterization process. It is used to activate CBD/THC components and is accomplished by carefully heating an extracted solution to release the carboxyl ring group (COOH).

The most common pieces of equipment are wiped film, molecular short-path stills. In this approach, the feedstock of oil is fed into a jacketed vessel that is often heated with an oil circulating TCU to achieve temperatures up to 343°C (650°F), though the typical distillation temperature range is 130 -180°C (266-356°F). In these systems, the feed stock is distributed on the evaporation chamber wall with a special wiper. The resulting thin film allows the more volatile terpenes to evaporate through the top of the chamber into their own external collection vessel, while the CBD/THC is collected along a TCU controlled central condenser unit which is cooler (typically 60-70°C / 140-158°F) than the evaporation chamber and serves to attract the cannabinoid vapor. The final step in the process is solvent removal, which is accomplished in a separate, external cold trap, which is also temperature controlled with a chiller.

Temperature Control Units (TCUs)

For CBD or THC extraction and distillation temperature control, Delta T Systems has the experience, expertise and capability to give processors and OEM equipment manufacturers standard or custom equipment to meet all aspects of the process’ requirements. All systems are designed for process repeatability. Our equipment lowers production costs, improves temperature accuracy, and delivers long lived quality and ease of maintainability.

Delta T Systems has developed a broad range of industry leading product features and capabilities that make our TCUs and chillers the best on the market:

Certain OEMs offer wiped film molecular short-path distilling equipment that integrates the removal of heavier materials directly into their distilling process. In this instance, chlorophyll, waxes and other heavier residue (up to 40% of the feed stock) descend the outer wall of the distillation vessel and are collected in their designated container.

Similarly, decreasing extraction temperature can lead to:

Temperature control is necessary throughout all the steps in the process, but precise extraction chamber temperature control is absolutely essential to managing final product quality and characteristics. This high level of control must also be replicable from one batch to another and in fact on a continuing basis over a large number of batches. Controlling temperature to within .275°C (.5 °F) is a standard that permits a consistent finished product. It is also important to note that repeatability, in addition to accuracy is extremely important for producers as it allows them to replicate the process over time, and thus insure consistent product quality.

There are quite a few different approaches to extraction and distillation of CBD/THC products, and each has certain benefits as well as some less desirable side effects; but they all have in common these parameters that need to be controlled: temperature, pressure or vacuum, source material throughput volume, and for extraction, solvent feed rate.

Vaping has become increasingly popular among medical cannabis patients, and for good reasons. The ability to change temperature for a more tailored experience is one. For another, vapers aren’t at risk of breathing in ash or smoke, which is potentially harmful in the long run.

Top 10 Temperatures to Care About

The two key players here are cannabinoids and terpenes. By looking at the most prominent subsets of these compounds, you can figure out the optimum temperatures for various effects.

Now for terpenes. Though not as familiar to most people, terpenes are the little hydrocarbons that give different cannabis strains (as well as other fragrant plants, like eucalyptus) their signature aromatic qualities. In cannabis, they are found in the plant’s sticky resin glands, where cannabinoids are also produced. Here are the five most common terpenes and their boiling points:

Choosing Your Vaporizer

First of all, there’s no such thing as the “perfect high” on a universal level. But depending on your individual expectations, you can do a few complicated little equations to ensure the right components activate at the right levels. Or, you could just copy our homework:

Cannabinoids (full definition here) are a number of chemical compounds found in a cannabis plant that interact with your body in different ways to produce unique medical benefits. The top five, each with varying boiling points, include:

Whether you choose to vape or smoke, the psychoactive effects of cannabis can depend on factors such as THC content, the plant strain, and the biological composition and tolerance of an individual person. But did you know that temperature can make a critical difference, too?
