The Ins and Outs of Botanical Extraction from Hemp and Cannabis

In recent years, there has been a lot of research and studies that suggest how versatile cannabinoids, specifically cannabidiol (CBD) which is found in hemp and cannabis plants, can be regarding health and well-being. Because of the interesting CBD benefits, cannabis and hemp botanical extraction has become a desired and popular process to obtain THC, CBD and terpenes for a multitude of products.

Here at PDX.Gold we offer a variety of hemp and cannabis extraction equipment.

BOTANICAL OIL EXTRACTION

Botanical oils are extracted from the biomass of cannabis and hemp plants. Cannabis oil contains multiple compounds including THC, CBD, CBG among others while oils extracted from hemp is very similar but contains no THC.

 

There are three distinct main methods in CBD extraction, each one having their own unique set of pros and cons. To properly extract cannabis oil, there is a variety of specialty extraction equipment that can be used, ranging from hydrocarbon closed-loop extraction systems to high pressure / temperature Carbon Dioxide systems to ethanol extraction systems.

 

Before diving into these methods, it’s essential to know exactly what these machines are removing from the biomass and why these extracts are so sought after.

What is Cannabis Oil?

Cannabis oil is the extract that comes out of the cannabis plant when using extraction equipment. This oil can contain over 100 different cannabinoids if unprocessed; however, the two main ones are cannabidiol (CBD) and tetrahydrocannabinol (THC).

 

CBD is the chemical compound that many believe has health benefits, as it’s been reported to combat pain and inflammation, acne and other skin problems, and potentially provide relief from mental health issues, such as anxiety and depression.

 

THC has been attributed to providing the “high” sensation when consumed, and thus needs to be considered when making CBD products because they can only contain less than 0.3% of THC to be considered legal in the US.

 

Another lesser-known compound found from cannabis and hemp extraction process is terpenes. Terpenes are aromatic oils that color cannabis with distinctive flavors and have been reported to promote relaxation and stress relief, while others report it promotes focus and acuity.

TYPES OF EXTRACTION SYSTEMS

Here at PDX.Gold we offer a variety of extraction equipment to support your business needs. Below are three types of extraction methods and equipment that are designed for numerous applications – everything from natural flavorings and essential oils to the growing market of CBD and cannabis products. Not sure which device you need? No worries, we've got you covered. Read through the different types of extractors and the suggested equipment, or just call to ask 1-503-783-6550 – we’d be happy to help. 

This is an extremely popular extraction method due to its ease of use and relative accessibility. For this type of oil extraction, hydrocarbons (such as propane and butane) are used as a solvent to extract the THC and cannabinoids. Hydrocarbon extraction is a very clean extraction method that leaves very little, if any, residue when utilized properly and also minimizes post processing requirements. The extract is clean and contains very high levels of THC, CBD, and terpenes.   Hydrocarbon extraction is the most effective of the popular extraction methods to capture terpenes.  Cooler temperatures are very efficient at extracting THC and cannabinoids while at the same time reducing the levels of plant pigments and waxes in the final product.

When properly trained professionals are involved in the hydrocarbon extraction process, there is very little risk. However, because flammable solvents are used, there is risk when used improperly. Again, if trained professionals are doing the extraction and using the proper extraction equipment, risk is low.

PDX.Gold equipment that supports hydrocarbon extraction include:

Ethanol Extraction

Ethanol is often used as the primary solvent when extracting CBD from hemp and is gaining popularity due to being highly efficient and safe. During the extraction process, ethanol combined with other solvents are mixed with the botanical material to remove the CBD and terpenes. Cooler temperatures are very efficient at extracting the cannabinoids while at the same time reducing the levels of plant pigments and waxes in the final product.  It is a more time-consuming process as the oils take longer to be separated from the ethanol solvent.

CO2  Extraction

This method of extraction is one of the “cleanest” methods used as any CO2 leakage or release does not constitute an environmental hazard.  CO2 extraction uses pressurized carbon dioxide and heat to extract oils from the biomass. When under the right temperature and pressure, CO2 acts as a solvent without the potential dangers that come with hydrocarbon and ethanol. This makes it an extremely safe extraction method. CO2 extraction allows no toxic by-products and can be used in a variety of industries, such as decaffeination of coffee beans and hop oil extraction for beer brewing, to name a few.

Though we hate to say we don’t offer CO2 extraction equipment, our goal, outside of providing you one of a kind, safe, efficient, and high-quality botanical extractors, is to provide you with the “purest and most decadent” hydrocarbon extraction method. Why? So, you can acquire the best and most versatile depth of THC and CBD product aromas, flavors and effects. Plus, our product delivery speed is hands down one of our clients’ favorite features. Who doesn’t want to increase productions levels without compromising product quality? Not us and we’re sure not you either.

CHOOSING A CANNABIS EXTRACTION SYSTEM: WHAT TO LOOK FOR

The three extraction methods – Hydrocarbon, Ethanol, and CO2  - are the most widely used today. Each extraction method is very different, and each has pros and cons. When choosing a cannabis extraction system, there are four things to consider:

Quality of Final THC and CBD Product

Hydrocarbon extraction, which uses solvents like butane and propane, are non-polar and tend to preferentially bind to the fat-soluble components of cannabis, thus providing a much more potent extract rich in compounds.  By controlling the temperature and pressure of the system, hydrocarbon extraction is the most effective for recovering terpenes in the extract. In addition, this type of extraction allows for flavonoids and carotenoids to be extracted, which means the aroma, flavor, and effects are as close as possible to the starting material.

Ethanol extraction is a good choice in terms of cost, but due to the polarity of ethanol solvents, this means the ethanol often binds to all the water-soluble components in cannabis, and this could result in a less potent final extract that might need further processing.

Though CO2 extraction is very efficient in extracting THC and CBD compounds, most CO2 systems operate at pressures and temperatures that damage or destroy the fragile terpene compounds.  Thus, many of the flavors and aromas of the original material is lost.  Most CO2 derived materials require flavonoids and terpenes to be re-added to the extract in post processing when used in products that demand them.

Safety Concerns

All oil extraction approaches are best conducted under the guidance of a trained technician in an approved extraction lab.  In these circumstances there is unlikely to be any danger.  Please note the following caveats: Hydrocarbon vapors are very flammable and explosions in non-approved “gray-market” labs have been known to happen.  Hydrocarbon extraction is generally considered to be safe as the systems are closed loop, meaning all the solvents are contained throughout the process.  Only in the event of a leak or equipment failure would there be any risk.

 

CO2 extractions are generally considered very safe. The equipment used for CO2 extraction ensures there isn’t any sudden release of pressure. Only if the equipment has a leak, for example, would there be any risk.

The ethanol extraction processes also use a flammable solvent. Ethanol extraction systems are also closed loop systems, meaning the solvents are prevented from mixing in the air and combusting, thus significantly minimizing any risk.

Output and Efficiency

Ethanol extraction allows for large batches of biomass to be processed at one time, which makes this technique an attractive option for those who require a high output process. Hydrocarbon extraction is faster than ethanol extraction, but the batch sizes used in hydrocarbon extraction systems are typically significantly smaller than ethanol systems.  The overall run-time of modern hydrocarbon extraction equipment allows production of a hearty amount of output within 24 hours. The CO2 extractions are generally much slower than the other two methods.

Equipment Costs

CO2 extraction has the highest equipment and running cost, including employing highly skilled technicians to operate the equipment.  Ethanol extraction is usually focused on processing hemp in exceptionally large quantities for CBD extraction.  Most commercial ethanol systems are constructed on an industrial scale and can be prohibitively expensive.  Hydrocarbon extraction is the most “scalable” and systems are available from very small individual systems for “gray market” use to industrial scale, automated computer driven systems.  There are hydrocarbon systems available to meet almost any budget.

Solvent Transfer and Recovery Systems (STAR Systems) are designed for n-Butane and Butane/Propane blends. They are an engineered system to deliver safety and performance perfection resulting in high quality results. Also, the STAR systems are ergonomic, durable, and simple to maintain.

Because all plant material contains water, during the oil extraction process, water may transfer to your solvent (e.g., butane), which can damage the recovery pump. To prevent this, a filter dryer is essential. Our CycloneDry filter dryers will eliminate this problem and are designed specifically for extraction done with hydrocarbon extraction systems which are closed loop systems.

 

Oil distillation uses heat and vacuum ovens and pumps to separate the CBD from less desirable compounds, such as solvents, fats and waxes. Vacuum pumps are a necessary piece of equipment required for proper distillation. After extracting the oils in ethanol, it must undergo an evaporation process so that only the desired material remains.

The rotary evaporator plays a crucial role in the extraction process because it efficiently removes extraction solvents by evaporation, without harming the product. Typically, the rotary evaporator is used in post-extraction refinement or recovery after ethanol extraction.
