Distillation is a science that has been used for thousands of years, but it’s now known as the final gateway to creating some of the purest forms of hemp and cannabis products. Extracting, isolating, separating, and distilling pure cannabinoids are among the top trends in the world of cannabis production.

Equipment and techniques for creating these pure products have developed almost exponentially within recent years. From potent THC distillate vapor pens to CBD tinctures, the distillation process is a key step in creating some of the most desired products in the industry.

The steps before distillation

Before we walk through the distillation process, we need to look at the steps that get us to CBD oils that can be distilled. In order to get those desired cannabinoids, they first need to be extracted from the plant.

The extraction of hemp or cannabis typically involves the following steps:

  1. Drying the hemp or cannabis to 5-15 percent water content.
  2. Shucking the flower from the stems.
  3. Grinding of the flower to 2-300 microns to enable more efficient extraction.
  4. Decarboxylating or removing carbon dioxide from the cannabinoids to make them neutral and activating the cannabinoids.
  5. Collecting of terpenes for later use in formulation.
  6. Supercritical CO2 extraction .
  7. Winterization and filtration of the extracts to remove waxes and fats from the extract.
  8. Removing any ethanol solvent from the winterized oil using a thin film distillation apparatus.

Once these steps have been accomplished, then the winterized CBD oil is ready for distillation.

What is CBD distillate?

Very simply, distillation is the separation of molecules through selective boiling and condensation. An example of this is practiced in the world of alcohol distilleries. In order to create a higher alcohol content in spirits like vodka or whiskey, a distillery needs to use distillation to separate other materials from alcohol. But how is it done?

Alcohol has a lower boiling point than water and is therefore more volatile, causing it to evaporate at a lower boiling point. Because of this, a distillery can use a set temperature (roughly 173 degrees Fahrenheit) to boil off the alcohol in a solution causing it to evaporate. After evaporation, the alcohol will collect in a chilled condensation column where it will be more potent and free of water and other unwanted residuals.

Now, let’s apply this science to cannabis concentrates.

Compounds separated through distillation

When we talk about distilling cannabis products, we have to consider what components we are separating from the plant itself. These can be broken down into a few categories:

Cannabinoids: These are the naturally occurring compounds in the cannabis plant that give it its unique profile and react with the body’s natural cannabinoid receptors. These include tetrahydrocannabinol (THC), cannabidiol (CBD), cannabigerol (CBG) and others.

Terpenes: Naturally occurring compounds derived from repeat units of isoprene. These compounds are found in cannabis, hemp, hops and other plants as well. Well known terpenes include limonene (lemons), pinene (pine trees), linalool (lavender), among many others. Terpenes are thought to contribute to the health effects of the cannabis plant although much research has yet to be completed.

Flavonoids: These lesser mentioned compounds are phytonutrients found in virtually all plants and are partially responsible for color, aroma, and flavor. While these aren’t quite as prevalent in the cannabis plant, they may play a role in the potential health benefits found in cannabis.

Fats and waxes : Class of hydrophobic high molecular weight resins that are produced by plants and may be extracted.

How to extract CBD

Now that we’ve looked at the scientific basics and the compounds we can acquire, let’s dive into the cannabis distillation process.

Take CBD for example. CBD’s boiling point is roughly 320-356 degrees Fahrenheit. A typical solvent used for extraction is ethanol, which has a boiling point of 173 degrees Fahrenheit. Because the ethanol has a lower boiling point than the CBD, it will evaporate first and collect in a chilled condenser separating it from the desirable plant components.

So, the leftover product should be nothing but pure CBD, right? Well, not quite. The product may still contain chlorophyll and terpenes. How do you remove these to make a nice, clear distillate? You use wiped film distillation equipment.

Common distillation equipment

Short path distillation

A common class that covers a range of distillation equipment is referred to as “short path” but really isn’t due to the fact that the condenser is external to the evaporator. More accurately termed “fractional distillation,” this kind of equipment is typically constructed of glass and is used for solvent removal and distillation on a laboratory scale due to its relative simplicity, small footprint, and lower price tag.

Thin film distillation

When it comes to cannabis products, it’s very important to incorporate thin film distillation . This will create a thin film of oil across an evaporative surface. This, coupled with vacuum pressure to lower boiling temperatures, ensures that the evaporated components (cannabinoids in this case) aren’t in prolonged contact with the heat source reducing the risk of damaging them. There are several variations of equipment capable of doing this.

Rotary evaporation

Likely the most commonly used equipment for solvent removal, rotary evaporators, or roto-vaps, utilize a rotating round bottomed flask to create a thin film. The heat source is reliant on a warm bath that the round bottom flask rests in. This is particularly good solvent removal at a small scale, but is discontinuous. This means it’s generally not a scalable technology if you have a lot of solvent to remove. They aren’t typically compliant with special fire hazard occupancy rules.

Falling film distillation

Similar to rotary evaporators, falling film distillation equipment is great for solvent removal and uses lower viscosity oils. This occurs by allowing the oil to drain down the inside of a heated column. This continuously creates a thin film on an evaporative surface before being collected on a chilled condenser.

Wiped film distillation

As a product becomes more refined, its viscosity increases. This means that typical methods of distillation like rotary evaporation or falling film evaporation aren’t as effective. Wiped film distillation machines use mechanical wipers that spread a thin layer of oil across a heated evaporative surface allowing the cannabinoids to evaporate and recollect on a chilled condenser that is only a short distance away. This is known as short path distillation. At this point, the final product could contain numbers of cannabinoids as high as 90 percent or more and should also be a nice golden color.

Why do distillates matter?

So, why go through all the trouble to grind, decarboxylate, extract, winterize, and distill a cannabis product? It all comes down to the final product.

On the product level, a distillate has the huge benefit of purifying key components of the cannabis plant that can be re-introduced with particularity. Through decarboxylation, extraction and distillation, desired components like CBD, THC, terpenes, and flavonoids become the basis of many different products including tinctures, edibles, topicals, and non-food supplements.

Typically, manufacturers will also sell bulk oil such as full spectrum distillate, broad spectrum, or crystal CBD isolates. Manufacturers use these to produce consumer products that are known in the market as full spectrum or broad-spectrum products.

  1. Full spectrum: These formulations contain cannabis plant components, cannabinoids as provided by the plant, and a full spectrum of terpenes. For CBD products, the THC is limited. Federal regulations only allow a percentage less than 0.3 percent of THC .
  2. Broad spectrum: These formulations contain CBD and a full spectrum of terpenes but not THC. However, they aren’t considered “THC-free” but are considered to be “THC non-detect” with the analytical method of choice. For example, THC isn’t detectable at 300 nm. Minor cannabinoids may or may not be present in broad spectrum oils depending on the plant. These formulations may be beneficial for consumers looking for the entourage effect , a synergistic effect of terpenes and cannabinoids that can amplify the beneficial effects of each compound without concern for THC content.

All of these formulations are reliant on a producer’s ability to purify each of the plant components through distillation. This way, any select combination of cannabinoids and terpenes can be created for a distinctive product tailored to the needs of the consumer. From the standpoint of a manufacturer, this is a crucial part of any cannabis market.

The future of cannabis products

Not long ago, the future of cannabis was on the horizon in the form of distillates, now the future is here. The ability to extract, separate, and reintroduce specific, purified cannabis components has opened a world of product formulation. Because of distillation, the world of cannabis has experienced these undeniable benefits:

  1. Consistently pure cannabis oils.
  2. The ability to create nearly endless product formulations.
  3. The opportunity to explore numerous health benefits of specific cannabis compounds.

Cannabis Distillate: Behind the Making of Pure & Potent Liquid Gold

Cannabis distillates are the ultra-refined extracts from the cannabis plant found in vape cartridges, edibles, and topical products worldwide. Distillates contain a single cannabinoid in pure and potent oil. Their amber-colored and translucent appearance does not start off that way. A series of extraction and purification processes convert the raw cannabis and hemp plant material into the marijuana distillate found in a significant amount of cannabinoid-based products.

In a world full of flavorful and aromatic full-spectrum concentrates, why does cannabis distillate seem to be everywhere? Why is this scentless and flavorless extract so coveted among producers? Our cannabis distillate guide breaks down the different distillate types, how they are made, and how they are used for medical and recreational use around the world.

What Is Cannabis Distillate?

As a new user, it can get confusing trying to wrap your head around the different types of cannabis extracts available. Simply put, cannabis distillate is a type of cannabis extract that has gone through a distillation process to create a pure product with nearly 100% CBD or THC content. During the distillation process, processors use distillation equipment to separate the targeted compound, particularly THC or CBD, from the solvent, and other compounds.

Cannabis and hemp are composed of hundreds of individual compounds including cannabinoids, terpenes, flavonoids, and other essential oils. In the end product, boiling techniques remove nearly all of the flavor and aroma that comes from the plant’s terpenes. While terpenes are believed to elevate cannabinoids’ therapeutic potential, they are not always welcome.

Since all of the wax, lipid, and undesirable plant matter is removed from the extract, distillates take on a translucent look. Its viscous and sticky consistency contains a nearly pure potency reaching up to 98% cannabinoids compared to the slightly lower levels (60 to 80%) of undistilled extracts.

THC Distillate

For high tolerance users or medical marijuana patients needing high doses of the inflammation- and pain-fighting tetrahydrocannabinol (THC) compound, THC distillate boasts an impressively high concentration of the intoxicating THC. Its psychotropic and euphoric effects can help treat pain, muscle spasticity, glaucoma, insomnia, low appetite, nausea, and anxiety.

CBD Distillate

Cannabidiol (CBD) offers a more subdued and non-intoxicating alternative to the cerebral effects of THC. CBD distillate contains no THC and a nearly pure concentration of CBD. CBD distillate is a powerful extract meant to reap all of cannabis’ and hemp’s wellness benefits without the high. CBD has been shown to help treat seizures, inflammation, pain, nausea, depression, anxiety, and migraines.

Terpenes and Flavonoids

Cannabis terpenes are responsible for the unique aroma of each cannabis plant strain. While terpenes are found in minor levels in the cannabis plant compared to cannabinoids, they offer a robust aroma that can fill a room. Flavonoids are found in even lesser amounts and are responsible for the colors in your buds. Removing these compounds helps processors produce a uniform extract that can be flavored afterward.

What Is the Difference Between Distillate, Oil, and Isolate?

Cannabis oil goes by so many names, it is hard to keep track. Cannabis distillate always takes on a viscous oil consistency. It is a type of cannabis oil, but not all cannabis oils are distillates. The term distillate is reserved for oils that have undergone a distillation process after the oil has been extracted, winterized, and decarboxylated. Cannabis oils such as live resin, butane hash oil (BHO), Rick Simpson Oil (RSO), or hemp-derived CBD oil are similar but not the same.

Many people confuse distillate and isolate since they both focus on a single cannabinoid. In fact, isolate is technically a type of distillate since distillation techniques are used to refine the cannabinoid extract. Cannabinoid isolates, however, are completely pure crystalline powder forms of the therapeutic compound. Think of distillate as a less refined but equally powerful extract that elicits potent effects.

How Is Distillate Made?

Making cannabis distillate starts with a cannabis or hemp seed and undergoes a range of cultivation, extraction, and post-processing steps to remove the cannabinoids, terpenes, and flavonoids from the biomass (flowers, leaves, and stems). Here is a complete rundown of the supply chain and process used to distill the most valuable cannabis compounds.

Extraction Process

Even before the distillation process is initiated, the cannabis plant must undergo multiple steps including being properly dried and cured after harvest. Once dried, the biomass can be extracted using a range of solvents including carbon dioxide, butane, and ethanol. The biomass is packed in a material column, drenched in the solvent, and may be further refined using color remediation techniques before ending up in the collection tank.

Some processors may perform a winterization on their extracts to remove fats and waxes using ethanol and cold temperatures. In addition, the extract may be decarboxylated to activate the acidic cannabinoids, such as THCA and CBDA, into their parent compounds: CBD and THC.

In the end, crude oil derived from the initial cannabis extraction process contains a THC or CBD concentration between 60 and 80%. The rest of the oil will be composed of different flavors and aromas (terpenes), vitamins, antioxidants, and other essential oils. After the extraction process, the oil needs to be further purified to become a distillate.

Distillation Process

Cannabis distillation equipment varies but the process is very similar among the different distillation methods. Distillation reduces the pressure inside the apparatus to purify the cannabinoid at the lowest possible boiling point. A distillation apparatus heats the cannabis oil to a specific temperature to evaporate the desired cannabinoid from the oil without degrading it and then condensing the cannabinoid vapor back into a liquid.

Through steam distillation and fractionation techniques, distillation equipment can remove the ethanol, carbon dioxide, or butane solvent and almost everything else besides the cannabinoid through multiple passes.

Generally, the short exposure to heat during the process reduces the risk of degrading the highly volatile cannabis compounds. In addition, the best equipment creates a thin film of the oil onto the evaporative surface for more uniform heating and evaporation. Compounds with higher boiling points usually fall downward with the force of gravity and agitation into a separate residual collection vessel.

Distillation Equipment

Cannabis distillation equipment ranges from small units for small-batch operators to industrial-scale models for larger operations. Running the crude extract through the equipment multiple times helps remove as much of the plant matter, terpenes, and flavonoids as possible. The first “pass” removes volatile solvents, gases, and water while additional passes remove terpenes and flavonoids from the final product.

Short Path Distillation

Short path distillation, also known as fractional distillation, is a purification method that uses vacuum pressure to lower the boiling points of the cannabinoids and terpenes. Since lower temperatures are used, the gentle short path distillation can carefully weed out the cannabinoids and terpenes from the end product without damaging them.

Short path distillation uses slow thermal heating to heat crude oil in a glass flask with a magnetic stirrer. As the temperature slowly rises, extractors can separate fractions of the distillate beginning with the terpenes and solvent. Each fraction is collected in a collection flask. There are usually three, one for terpenes and highly volatile compounds, another for CBD or THC, and the last one for cannabinoids with high boiling points.

Wiped Film Distillation

Wiped film distillation is a type of short path distillation. Under a vacuum, the cannabis oil is loaded onto a heated and rotating vertical cylinder. Wipers continuously wipe the extract creating a thin film on the evaporative surface. A chilled condenser in the center of the wipers condenses the THC or CBD vapor. Different collection vessels collect the CBD or THC distillate and any heavier compounds such as chlorophyll, wax, and salts below.

Rotary Evaporation

Rotary evaporation techniques use rotary evaporators, also known as roto-vaps, are common in the removal of the solvent from the final product. In a rotary evaporator, the pressure drops using a vacuum pump which reduces the boiling point of the solvent. A rotating distilling flask is filled halfway and heated using a water bath. The distillation flask is rotated creating a thin film of the cannabis concentrate. This increases its surface area to speed up the evaporation rate.

Falling Film Evaporation

Falling film evaporators include an evaporator and condenser and use a different boiling point to separate compounds from the cannabis concentrates. Using this method, the oil is drained from above into a heated column and falls downward creating a thin film on the evaporative surface. As the cannabinoids evaporate, they are collected on a chilled condenser. Due to its unique methodology, cannabinoid products with lower viscosity work well under this process.

How to Use Cannabis Distillates

THC and CBD distillate can be used in a variety of ways for medicinal and recreational consumption. Its versatility makes it a favorite among extraction companies and consumers. Smoke it, vape it, cook with it, or make soothing lotions and creams infused with THC or CBD. The possibilities are endless. Cannabis distillate can be found in a majority of products sold in retail shops today.

Dab Rig/Portable Vaporizer

Cannabis concentrates such as distillates are commonly consumed, or dabbed, with a glass dab rig or electronic nail (e-nail). Dab rigs and e-nails are great for use at home since they can deliver large doses using heated surfaces. E-nails, in particular, can maintain consistent temperatures using a digital controller and power source to perfectly vaporize cannabis oil. E-nails offer the convenience of not having to use a torch and estimate your heat up and cool down times for your nail.

Portable vaporizers and certain battery-operated vape pens are good for on-the-go consumption. Many vape pen cartridges contain CBD or THC distillate (some with additional flavors) that can be disposed of when finished. Other portable vape pens feature a heating chamber that can be reloaded with a CBD or THC distillate.

Pipes, Bongs, Joints

While dabbing distillates is the recommended method of consumption for sky-high potencies, many users may also smoke their distillates to enhance the potency of their dried cannabis flower. Simply add a tiny dollop of your cannabis oil on top of a packed bowl or within/outside your joint for an enhanced effect.

Edibles

Cannabis distillates are a favorite ingredient in the making of edible products. Distillates can be infused into your favorite foods or beverages. Add this already decarboxylated oil directly onto your finished meal or use it as an ingredient as you cook. A distillate’s flavorless and odorless form allows you to create edible products that do not have the tell-tale taste and smell of the cannabis plant.

In addition, you can consume distillate sublingually for faster absorption and onset of effects compared to ingestion. It is recommended to bind the distillate to a carrier fat such as coconut oil, MCT oil, butter or other food-grade oil for better absorption since THC cannabinoids bind to fat. While the extract is already decarboxylated, it still needs help absorbing into the mucous membranes under the tongue. Warm up the mixture, stir until it is dissolved, and it is ready to go.

Topicals

No matter what cannabinoid distillate you buy or produce, you can infuse it into a variety of topical products including lotions, creams, and salves. Recipes require cannabis distillates and a carrier oil such as coconut oil along with your favorite essential oils for aroma. The salve infused with cannabinoids can be applied directly to the affected area for localized relief without the high since the cannabinoids cannot reach the blood-brain barrier.

Why is Distillation Important?

Through distillation, operators can purchase a greater volume of marijuana trim or low-quality biomass and distill their desired compounds into an ultra-potent liquid.

Distillates have become the backbone of the marijuana derivatives market. Find them in nearly every product category. Their flavorless and scentless characteristics help create a consistent and repeatable cannabinoid product.

Those infused gummies and chocolates we all know and love are only possible with a foundation of distillates. And, if you are a fan of aromatic terpene compounds, they can be reintroduced back into the final product.

Temperature Control for CBD/THC Extraction and Distillation

The legalization of the hemp cannabis derivative CBD and of marijuana and its THC derivative for medical and recreational purposes in many US states and all of Canada has led to significant economic growth in the CBD/THC extraction and distillation equipment sector. Many of the manufacturers of these two categories of equipment have been in business for a number of years, and the processes used for extraction and distillation have been refined over decades since they are used to extract and purify many different organic substances, chemical, petrochemical and alcoholic beverages. However, hemp and marijuana have their own unique characteristics, and the processes to extract and purify CBD and THC from their respective plant sources are still being fine-tuned by processors and original equipment manufacturers (OEMs).

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.

Extraction Process – Temperature control considerations

Current extraction processes include CO2, butane or propane, and ethanol. In each of these methods, the extraction agent is cooled down to temperatures that can reach -80°C (-176°F) and then compressed until it is liquefied. The temperature reduction is achieved using a chiller, which can be a standard piece of equipment or a custom unit designed to meet unique temperature profile requirements.

In commercial systems, extraction is typically performed in a jacketed vessel. Water, oil or other liquids are circulated within the jacket by a temperature control unit (TCU) which maintains consistent vessel wall and extraction chamber temperatures.

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.

For example, increasing the extraction temperature from the initial agent temperature can:

  • decrease the concentration of terpenoids in the extract
  • risk denaturing the final CBD/THC product
  • increase wax/resin extraction and overall volume, but yield a lower quality product

Similarly, decreasing extraction temperature can lead to:

  • increase the concentration of oil in the extract
  • reduce the wax proportion of the extract

For these reasons, having equipment that is capable of consistent and accurate temperature control is very important to producers; and as there is demand for many variations of this extraction process’ final product, chilling equipment and temperature control units with high precision, closed loop controls are critical.

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).

Distillation Process – Temperature control consideration

A distillation process is then conducted to complete the separation of the remaining elements and produce the purest possible CBD or THC oil. It is worth noting that even though a source material has been winterized, as much as 40% of the remaining feedstock may consist of undesirable materials. Also, in the case of ethanol extraction, ethanol must then be evaporated to separate it from CBD/THC components.

As in the extraction process, the distillation process that is used to fully purify CBD/THC oils requires closely controlled temperature, pressure and source material feed rates to ensure that the necessary interactions produce a high-quality finished product with characteristics that generate the highest possible value.

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.

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.

In certain cases, a final separation step is taken to separate THC from CBD. Crystallization is a common method. A reactor vessel is filled with feedstock and a solvent which is chilled slowly from 60°C to -20°C. A slurry results and that is transferred to a Nutsche filter dryer to produce pure, dried crystals. The Nutsche filter is a jacketed vessel whose temperature is controlled with a circulating hot oil unit. The process results in a 98% or higher purity of the CBD or THC product.
