There are some important facts about solventless cannabis extraction. The first is that solventless extraction methods are safer than traditional extraction methods. Furthermore, they are cheaper. Let’s take a look at how this processing technique works. You’ll be surprised that it’s much cheaper and safer than traditional extraction.
Solventless is a Solvent-Based Cannabis Processing Technique
Often referred to as solventless extractions, solventless processes involve mechanical extraction processes that do not use solvents. Water is a universal solvent, but some extractors use it incorrectly. Although some terpenes will dissolve in water during extraction, resin heads are never completely submerged. This makes solventless concentrate different from those made through solvent-based methods.
Cannabis consumers are becoming increasingly health-conscious, seeking clean, potent products that contain fewer chemicals than their traditional counterparts. As a result, solventless processing methods are increasingly gaining popularity. Cannabis connoisseurs also gravitate towards this method, which helps preserve the original plant material.
Another example of a solvent-less cannabis product is rosin. Rosin is produced by pressing cured cannabis nugs in a press that is heated to a high temperature. A rosin press consists of two plates clamped together on top and the other on the bottom. Once the cannabis nugs are squeezed, the substance will ooze out a smokable resin.
It Uses Physical Agitation
Solventless methods are much easier to use than traditional solvent extraction processes. This is because they use physical agitation to break down the plant material. As a result, the solventless process is often less expensive and easier to use, and it does not require a closed-loop extraction system. Instead, a solventless extraction technician agitates the flower over a fine mesh.
Solventless extracts like California solventless are gaining in popularity due to their high purity. The solvent-free process uses ice water to agitate plant material and knock off trichomes. The water is then passed through increasingly fine filters to isolate cannabinoid-rich trichomes. Dry ice is also sometimes used to make solventless hash oil.
The physical agitation method is not without drawbacks. First, physical agitation takes longer to clean objects. Secondly, it requires less power. Lastly, it takes longer to clean parts, making it a less economical option. In the end, the ROI must be determined.
It is Safer Than Extraction
Using solventless extraction can be safe for the environment and the health of extraction workers. Because there are no flammable solvents to dispose of, it can also eliminate the need for health and safety protocols. This type of extraction can still produce high-quality products, but it has specific temperature control requirements. For example, large-scale solventless extraction requires large volumes of cold water and ice, so it is essential to have specialized water service.
The extraction process is not entirely solvent-free, leading to residual water activity and microbial growth. Although solventless extractions don’t use solvents, they should still be tested for mycotoxins. For the sake of safety, solvent-based extractions are not recommended for use in home cultivation.
Butane is a highly volatile organic compound. Even low-level amounts can cause harmful vapors to form. High concentrations can be fatal.
It is Cheaper
Solventless extraction labs are more affordable and easier to operate due to the smaller initial investment and lower overheads. The increased demand for the products can also mean higher profits, as a premium grade of solventless rosin can fetch over $100 per gram in a dispensary. Solventless labs also produce cleaner, more natural products.
Solventless processes are also more versatile, as they can produce a wide range of products and grades. Since they don’t use flammable solvents, these methods are cheaper for small businesses and the environment. Moreover, solventless extraction methods require fewer equipment and fewer complicated waste disposal requirements.
Another advantage of solventless labs is that they cost less to purchase. Starting a solventless lab only requires an investment of about $35,000 – $45,000 while setting up a CO2 or BHO equivalent facility can cost more than $200,000. In addition, solventless extraction units are also easier to operate, require fewer supplies, and cost less than other extraction methods.
