Supercritical CO2 extraction (SCFE) is a safe method of efficient botanical extraction using a clean, non-toxic solvent ideal for cannabis, hops and more. Eden Labs is the proven brand for delivering the highest-yielding, most-reliable CO2 systems for commercial and industrial use. In late , Eden Labs announced the production of the Hi-Flo™ FX2 extraction system, a Supercritical Fluid Extraction machine re-engineered from the. Learn how CO2 cannabis extracts are produced and familiarize yourself with the science behind this versatile extraction method.

Proper cleaning will also help avoid any cross-contamination when switching between cannabis strains. For cleaning and maintenance tasks that are performed less frequently changing filters, cleaning valves, etc. If your system requires parts that could be considered consumables filters, seals, O-rings , I would recommend keeping several on hand, so you can change them out when needed and avoid downtime.
But similar to producing top-quality flower, producing extracts blends art and science—no easy feat for industry newcomers or veterans alike. For this reason, Cannabis Business Times reached out to two extractors to gather their tips on best practices, safety measures, and increasing quality and yield for two different extraction processes. With this data, some companies will successfully focus strictly on cartridge sales, but the cartridge industry is destined to become competitive and saturated.
I believe many companies will produce a vape cartridge that is no better nor cheaper than the rest, and these companies will suffer due to little or no brand recognition and will struggle to compete with products that possess strategic advantages such as the ones mentioned. Therefore, extract companies need to find means to efficiently produce a diversified range of concentrates—and not rely strictly on vape cartridge sales. Consumers will ultimately demand a wide range of products and offerings.
In turn, many will prefer to purchase superior- tasting, connoisseur-quality products over artificial or formulated flavors or poor-quality concentrates. If the superior offerings are affordable, that is all the better for the consumer. In the first part of this special extracts series, we reviewed a wide range of concentrates concocted from different extraction processes. See the sidebar to on p. This is where production economics come into play. Each extraction apparatus, whether CO 2 , ethanol, butane or a hand-press, requires labor of some sort.
Some are more user-friendly than others. Typically, the more complex an extraction and refinement method is, the more training the technician will require. Therefore, a highly trained technician or an employee with a Ph. It all depends on what you want the final form to be and how much it costs to produce. Rosin, dry-sieve or water hash require more rudimentary equipment, and employees producing these products do not require extensive equipment training.
Comparing the material and labor costs of CO 2 extraction to that of rosin presses reveals a stark dichotomy: CO 2 extraction equipment can cost hundreds of thousands of dollars, while commercial rosin presses might cost a few thousand. Odds are, the person operating the CO 2 equipment makes a higher wage than the rosin-manufacturing technician. What follows is an abbreviated explanation of the idiosyncrasies and strategic advantages of each method and the associated requirements of each regarding ancillary costs.
Most of these concentrate forms can be refined and manufactured into a multitude of consumer goods and products. The key to efficiency is to determine what final extract form you desire, then decide which method or apparatus suits your requirements, and how that equipment and the resulting ancillary requirements fit within your business plan. I have seen many interesting things in my years of concentrate consulting.
For example, one individual who insisted he could produce a better rosin press went to China, had some sort of press fabricated and shipped it to Oregon where it has sat unused for two years, never to press a speck of cannabis. Another group called me rand stated that their intent was to take hydrocarbon extract and increase its value via further distillation, which I explained was unlikely unless they were extracting very poor-quality hydrocarbon extracts. The point from these two misadventures is this: Figure out exactly what concentrate form fits your business plan, then figure out exactly which method suits your needs and stick to it.
Fire requires three elements to occur: Remove any of these elements, and fire cannot occur. Upon initial assembly, pressurize your entire system to 25 psi to 50 psi overnight to help ensure a leak-free system. Pack the column to the point that you feel resistance, but the plant material springs back. Channeling occurs when the solvent takes the path of least resistance around plant material that must come in contact with the solvent.
Locking up moisture in the plant material by making it ice avoids the water mixing with your butane and acting as a solvent on less desirable, water-soluble compounds like chlorophyll—which can contaminate your final product. Running with an in-line desiccant dryer will also keep unwanted water from your gases, avoiding undesirables in your finished product and adding life to your expensive pumps.
When running under cryogenic conditions, solvents can all condense to a liquid state. This creates equilibrium in the system and no pressure differential to move your solvent through your plant material. Band Heater or Boiler: This is often called fractional distillation, despite being a simple vacuum distillation technique intended to separate the cannabinoids from other components of refined cannabis oil.
Cannabinoids are not efficiently separated from each other with this technique. This process diminishes the boiling points of the target components of the cannabis oil i. That vapor is re-condensed in a different physical location and used in product formulation. Advanced techniques include wiped film and centrifugal distillation systems.
A process that is capable of isolating individual cannabinoids from a refined oil or distillate to percent purity. Each of these has individual strengths and weaknesses. A cylinder or a series of cylinders usually made of stainless steel where solutes concentrate after the extraction process.
The isolation of cannabinoid crystals via the production of a supersaturated solution, rudimentary liquid-liquid separation, temperature change and solvent removal. This process is often performed under a neutral atmosphere to avoid degradation.
Co2 Extraction Tips
Curious about CO2 extraction? The experts at Honest Marijuana tell you everything you need to know about CO2 cannabis concentrates. Several common forms of cannabis extraction rely on a solvent, such as Cannabis CO2 extract being dispensed from a supercritical CO2. In recent years supercritical CO2 extraction (SC-CO2) has become an effective and popular approach for creating cannabis concentrates.
