Before any CBD oil, THC tincture, weed butter or cannabis concentrate can be bought, first, it must be extracted. This is the job of cannabis extraction equipment, the machines that remove the coveted cannabis compounds from the plant’s matrix (a process explored in more detail here).

And just like any other piece of kit, an inevitable question arises when considering extraction machines: which one’s the best value for money?

Some are industrial, some are the size of a kettle. Some use CO2 as a solvent, others utilize alcohol.  All have their pros and cons which can be listed in a nice, handy guide to cannabis extraction equipment and machines. A guide just like this:

CO2 Cannabis Extraction

CO2 might not be the cheapest solvent going, but its benefits can be worth the price tag. In these machines, high heat and pressures turn the gas supercritical, enabling it to extract higher yields than many other solvent methods.


The BOSS CO2 Extraction System 

Automation at all stages has already improved the extraction process, especially with regard to repeatability and accuracy. Quadron Cannatech focuses on developing automated extraction systems specifically for the cannabis industry. Its BOSS CO2 Extraction System incorporates automated controls that eliminate the use of manual valves and has been designed to make load and unload times as short as possible to increase production capacity. The company claims that by streamlining the process its setup can process 20 pounds of cannabis material in 4 hours and run continuously without supervision, enabling a total of 6 runs per day.

The price: $4000

Pros Cons
One of the cheapest extractors on the market Very low capacity
Ideal for small, irregular use Incapable of mass production
Affordable Practically necessitates expansion packs

Alcohol Cannabis Extraction

Like CO2, alcohol is one of the most commonly used solvents for cannabis extraction. Cheap to source, the ethanol soaks up the prized compounds, which can then be separated via evaporation. But this cheap solution doesn’t come without its challenges. Ethanol is highly flammable, and any temperature change can drastically alter the final product. Luckily, these machines come with instruction manuals.


Across International Rotovap 

Built more like a home chemistry set than an industrial extractor, Across International’s Rotovap might be the perfect choice for a savvy buyer. Plus, thanks to its smaller volume, the Rotovap offers much more control over the evaporation of liquid phase materials. Any downsides, of course, stem from the extractor’s stripped back design. For example, any cooling system will have to be purchased separately.

Pros Cons
Suitable for home-use Very low production capacity
Easy to use Alcohol extracts can require extensive clean up
Does not require harmful solvents Not suitable for commercial extraction

ESCET  

Part of the evolution of any form of equipment comes from the introduction of new methods. ESCET, for example, have developed a method that enables cannabis extraction with low-proof alcohol, such as bourbon or vodka, plus vegetable oil and water. The company claims that this method is “non-flammable, has no moving parts, and operates at normal pressure.” As the process is currently patent pending, data to prove the efficacy of this method are promising but unavailable.

The price: unknown. 

Pros Cons
Does not require harmful solvents Not commercially available
Very easy to use No public data available to prove efficacy
No dangerous chemicals or equipment required Alcohol extracts can require extensive clean up

Butane Cannabis Extraction

Butane, or propane in some instances, can be seen as similar solvents to CO2 in many ways. The butane is pressurized and heated, which transforms it from liquid to a vapor, making it easier to remove. This process creates a shatter, a clear material of THC, CBD and other cannabis compounds like terpenes. Although effective, the process can be undesirable for medicinal products, due to the risk of contamination.


The PX40 Extraction System  

Throughput and scalability have been the focus of manufacturers of hydrocarbon solvent-based extraction equipment too. Precision Extraction Solutions, for example, continuously update their flagship PX40 Extraction System, which is ominously known as the Executioner. Run using either butane or propane, or a mix of both, this system can process up to 360lbs of material in a 10-hour shift of runs. The $189,000 price tag comes with the assurance that any extractor will be able to process vast amounts of cannabis using a machine that has been built above and beyond regulatory compliance. Plus, on-demand heating and chilling enables maximum control with ease of operation.

Ablaze Mini Closed Loop Extractor 

And here it is, what might be the cheapest butane extractor on the market: Ablaze’s Mini Closed Loop Extractor. With a 45g capacity and a 100psi limit, this processing product might only be capable of the most humdrum extractions, but for those interested in a saving, this is one of the best deals out there.

The price: $510

Pros Cons
Low price point Not as simple as at-home alcohol extractors
Suitable for home-use Very low production capacity
Easy to use Vaccum pump and recovery tank also required

Ice Water Extraction

More ‘back-to-basics’ than other extraction methods, ice water extraction isn’t a step too far from giving the cannabis plant a cold bath. Because THC is denser than water, the compound can separate from the leaf material when washed. After this, the cannabinoid-rich water only needs to be filtered through a series of micron bags before it’s ready to be used.


Eberbach Model E5703 

Working to create a safe and easy method for cannabis extraction, collaborators at Mountain High Suckers and Eberbach have developed a commercial platform that enables ice-water extraction, which eliminates any concern of residual chemicals in extracts. Plus, putting cannabis material in ice water and then filtering it is an extremely safe process. Currently available on their website, the Model E5703 can process over 1lb of plant material per hour and has been designed to comply with existing FDA standards. They are yet to release detailed information on the results of their experimentation, but the technique holds promise for small scale extraction and could potentially be scaled up to process more material.

The price: approximately $10,000

Pros Cons
Does not require harmful solvents Methodology still in development
Very easy to use Scalability unknown
No dangerous chemicals or equipment required No public data available to prove efficacy
Cheap to run Ice water extraction is non-specific
Suitable for small scale operations Water-based extraction can be slow

 

Funding cannabis extraction equipment 

Getting real equipment takes some investment in a business and can be a huge barrier to start-ups with some setups costing hundreds of thousands of dollars. To help overcome these hurdles, companies such as Trust Capital have been set up to offer financing for cannabis equipment. If a manufacturer wants to make a professional extract, professional equipment must be used. Another approach is to borrow or lease the extraction equipment your business requires, enabling you to get off the ground without making any large capital investments and potentially explore various production methods whilst you are developing your ideas. For example, Apeks, a manufacturer of CO2 extraction systems, offer their equipment on lease for anything from a week right up to two years. They even throw in free servicing and in-depth training on the system.

As this industry grows, so will the equipment options for extraction. These advances will probably go across the kinds of extraction processes, and the connection between extraction and analytical testing could also see improvement. Even with the best equipment, though, only skilled operators can produce the intended results. So, training operators as needed should always be performed in any company to guarantee results.
