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. A mixture of cannabis oil, water and an emulsifier. A cylinder that is usually made of stainless steel where plant material is packed and where a solvent is injected to remove solutes from the parent material.
The process that uses a solvent i. A product that undergoes minimal refinement—usually only winterization and clarification—that includes all of the major components of cannabis i. A purified individual cannabinoid at plus percent resulting from a chromatography process. An emulsion that contains micelles that measure within the nanometer range. An apparatus that controls the pressure of the solute in the extraction and collection vessels.
A part of a closed-loop extraction system that conducts the solvent phase change and houses the recycled solvent prior to re-injection to the extraction vessel. Refined Extract or Refined Oil: The product resulting from undertaking the winterization and clarification processes after the initial extraction.
This is a cannabinoid-rich oil or sap that is usually yellow to red in color. The second—or downstream—stage of the extraction process where the target compounds i. Some technologies have the ability to separate the compounds in multiple ways based on molecular weight i. A refined extraction product that contains high concentrations of acid-form cannabinoids; it is crystalline and usually used for dabbing or vaporizing. It can also be consumed orally to obtain high dosages of acid-form cannabinoids.
A substance of interest in feed material i. In the cannabis industry, the cannabinoids, terpenes, flavonoids, etc. The recovery of the winterizing and clarification solvent with the application of heat and vacuum. The most common techniques include rotary evaporation and falling-film evaporation. A substance with properties that promote the dissolution of solutes from the parent plant material. The most common examples in the cannabis industry are butane, carbon dioxide and ethanol.
A refined extract that contains large amounts of terpenes and a moderate concentration of cannabinoids. It is usually liquid or sap and commonly used for dabbing or vaporizing. A product that can be derived from a full-spectrum oil or distillate formulation often used in a small vaporizing cartridge or larger vaporizer.
Sometimes oil viscosity is manipulated with polyethylene glycol, propylene glycol, alpha bisabolol or medium chain triglycerides. Wax or Crude Extract: The product first obtained from the extraction process. It contains all of the solutes extracted from the plant material i.
Mostly applies to products from carbon dioxide extraction. The process where crude extract is dissolved in ethanol at warmer temperatures i. Cannabinoids and terpenes are soluble in ethanol at the cool temperatures. Shatter is a form of "absolute" extract in cannabis. Finally, one distinct advantage of CBD oil over THC oil — besides the fact that a completely opposite effect is experienced from consumption of each product — is that hemp plants are very high in CBD and are legal throughout much of the world.
Hemp plants are employed in the production of tens of thousands of industrial products and their high CBD content means that hemp waste from the production of such goods can be recycled to make CBD oil.
Since the main point of using CBD oil is to remove any non-active components of the plant, the most effective approach to producing CBD-rich oil is to use high-CBD plant matter as a raw ingredient. Once the perfect strain has been selected, a manufacturing method should be chosen. The Cannabis industry is rife with varying extraction methods; each has its advantages and disadvantages.
Those seeking the purest, cleaned CBD oil possible will likely employ a different method than commercial producers. The cost, relative safety and potency of the product is directly controlled via method of extraction.
The procedure of manufacturing CBD oil products via oil-based extraction is rapidly gaining in popularity. The safest method in terms of not making anything or anyone explode, oil extractions also provide a dose of healthy Omega acids if hemp seed oil is employed as the carrier; olive oil is also a commonly-used carrier oil.
Since the oil-filled trichomes are fat- or solvent-soluble, natural plant oils are an effective way to extract the cannabinoid-laden resin. An added benefit is the lack of potentially harmful chemical residue that is deposited in the CBD oil by other extraction methods. One major downside of oil-based CBD extractions is that most carrier oils have a limited shelf life.
This means that smaller batches should be produced for personal use and proper storage should be a concern. Also, this product is best eaten or applied topically, rather than being smoked. Generally considered the safest method of extraction, this is also the cleanest. More scientific and careful than other methods, super- or sub-critical extraction employs extremely high or low temperatures to provide a protective environment in which the cannabinoids are preserved and isolated.
Due to the highly-controlled aspects of this process, the integrity of the cannabinoids and thus, the purity of the oil is maintained. In addition, the green chlorophyll is removed from the end product, leading to an extremely clean-tasting product. This particular approach may not present the best alternative for many small-scale producers, especially those who are making CBD oil in order to save money.
Expensive, technically-complicated equipment is required, the operation of which usually takes a while to perfect. Although the quality produced is potentially the highest, in addition to potency, this method usually requires a large financial investment, as well as the investment of much time and trial-and-error experimentation, until a perfected process is achieved.
Additionally, the major drawback of the super-critical method is that heat can damage the delicate terpenes — the elements responsible for the flavour and scent of each strain, as well as therapeutic benefits — during the decarboxylation process.
The solvent method is the approach most commonly taken by small-scale CBD and THC oil producers, primarily due to its relatively low cost, easily-obtainable required equipment and simple process; unfortunately, this is also the most dangerous technique. The solvents most typically employed are butane, grain alcohol, isopropyl alcohol, hexane or ethanol.
There are several reasons to avoid this method. Firstly, the use of solvents always brings about the potential for explosions. Secondly, it is difficult — if not impossible — to completely remove any and all traces of the solvent from the end product, reducing the safety of the substance and essentially removing the justification of using CBD oil over simply smoking pot. This can negate any positive aspect of choosing to medicate with Cannabis oil, potentially worsening existing medical conditions or leading to new ones.
A third reason for avoiding solvents is that this method can actually destroy some of the therapeutic plant waxes, decreasing the overall medicinal value and recreational quality of the oil. Solvent-based extraction processes do not produce as clean of a product as CO2 extraction, for example. Since some chlorophyll is also extracted via solvent use, the end product may not impart the same taste that results from CO2 extraction.
This process yields about two to four grams of extremely potent, medicinal-grade CBD oil that is suitable for ingestion. After a few practice runs, the entire process for small-batch edible oil production should take about an hour, including around thirty minutes of cooking time.
Grain alcohol is the solvent that is least likely to leave impurities or residue in the final product. Find a larger bowl before proceeding further, if necessary.
This enables the resin glands to dissolve into the solvent. Make sure that the plant matter is thoroughly saturated and has had a chance to expel its resin content.
Pour the dark green liquid from the mixing bowl into the bag or sieve; allow the liquid to be filtered completely and pour into the container. Gently massage the bag in order to squeeze out as much liquid as possible. At this point, many people repeat the previous four steps in order to extract as much resin as possible into the solvent. This second wash should remove most of the remaining resin. Fill the bottom of the double boiler with an appropriate amount of water. If your alcohol-resin solution does not all fit in the top of the double boiler, you can keep refilling the pot as you boil down the CBD oil, eventually processing all of the rinse liquid.
When it reaches the bubbling stage, turn off the burner — the residual heat contained in the water bath will continue heating the mixture, allowing the alcohol to evaporate.
The evaporation step usually takes between fifteen and twenty-five minutes to complete. The mixture should continue bubbling throughout the evaporation process. As the alcohol level decreases, so will the amount of bubbles.
