Solvents and solventless methods are both used for cannabis extraction. Solvents are liquids that are used to dissolve the cannabis plant material and extract the desired compounds, such as THC and CBD. Common solvents used in cannabis extraction include ethanol, butane, and CO2. Solvent-less methods, on the other hand, do not use any liquids to extract the compounds from the plant material. Instead, they rely on mechanical means, such as pressure and heat, to separate the desired compounds. Examples of solventless methods include rosin pressing and ice water extraction. Both methods have their own advantages and disadvantages, depending on the desired end product, the scale of the operation, and the regulatory environment.
HASH VS ROSIN
Hash is a type of cannabis concentrate made by separating the trichomes (resinous glands containing the plant's cannabinoids and terpenes) from the plant material using a mechanical process such as sieving or ice water extraction.
Rosin is another type of cannabis concentrate made by applying heat and pressure to cannabis flowers or hash to separate the trichomes from the plant material. Both hash and rosin are used for dabbing or vaporizing, and can also be used to make edibles or topicals.
RESIN VS ROSIN
Resin and rosin are two different substances that are produced from the cannabis plant.
Resin refers to the sticky, gooey substance that is produced by the cannabis plant, particularly in the buds and leaves. This resin contains the plant's cannabinoids, terpenes, and other compounds, and is typically collected using solvents like butane or CO2. The resin can then be further processed to create products like hash, wax, and shatter.
Rosin, on the other hand, is a solventless extract made by applying heat and pressure to cannabis flowers or hash. This process causes the resin to separate from the plant material, creating a liquid that solidifies into a wax-like substance. Rosin is known for its purity and terpene retention, and it's becoming a popular method of extraction because it's simple, safe, and affordable.
Both resin and rosin contain high concentrations of cannabinoids and terpenes, but rosin is considered to be a cleaner, more natural alternative to the solvent-based resin.
Rosin is a solid form of resin that is obtained by heating liquid resin to vaporize the volatile liquid terpene components. It is used as a sealant in construction and as a flux in soldering and tinning, as well as in the manufacture of varnishes, printing inks, and soaps. It is also used in the production of rosin-based violin and bow rosin, which is used to increase friction between the bow and strings of stringed instruments. It is also used to make rosin-based products for dance and gymnastics, including rosin bags and rosin powder, which are used to increase grip on surfaces such as dance floors or gymnastics equipment.
HOW TO SCALE SOLVENT-LESS
There are several ways to scale solvent-less processing, including:
Increasing the size of the equipment: Larger equipment can process more material at a time, which can increase the overall yield and efficiency of the process.
Automation: Automating certain steps in the process can reduce labor costs and improve consistency.
Improving the efficiency of the process: Optimizing the process to reduce waste and increase yield can help to scale the process more effectively.
Multitasking: Running multiple process simultaneously can increase the output and scale the process.
Investing in R&D: Investing in research and development can lead to improvements in the process and new ways to scale it.
It's worth noting that solvent-less processing is generally considered a low-volume, high-value application, so scaling it may be limited by market demand rather than technological limitations.
Solvent-less extraction methods have several benefits over traditional solvent-based methods. These include:
Safety: Solventless extraction methods do not involve the use of potentially hazardous chemicals, making them safer for both the environment and the people handling the materials.
Purity: Solventless methods typically result in a purer final product as there is no residue from solvents left behind.
Flavor: Solventless methods tend to produce a product with more natural flavors and aromas, as the process does not strip away any of the naturally occurring terpenes.
Cost-effective: Solventless methods are typically less expensive than solvent-based methods as they do not require the use of costly solvents.
Legal compliance: Solventless methods are legal in most countries, while some solvents used in solvent-based methods may be restricted or prohibited.
Scalability: Solventless methods are also more scalable as they do not require costly equipment such as rotary evaporators, which are often needed for solvent-based methods.

We design-to-build customized 3-part solvent-less systems complete with innovation and automation for your company to compete with all forms of concentrate in the marketshare. We take accountability for the equipment's ability to scale efficiently and effectively in-order to streamline your companies production. From floor plans to consulting, we have you covered. As a manufacture / processor, your equipment and workflow efficiency is the most important asset to your company. It is required when considering how to adapt to an increase in demand for rosin, with a 30% annual growth rate overall.
Additional equipment such as a trimming machine, flower dryer, and storage containers may also be necessary.
The cost to begin solventless cannabis extraction can vary depending on the scale of the operation and the specific equipment used. A small, home-based operation may cost several hundred dollars for a basic rosin press and necessary supplies, while a larger commercial operation may cost tens of thousands of dollars for specialized equipment and facilities. In general, the cost of starting a solventless extraction business will be lower than that of a solvent-based extraction business due to the lack of expensive solvents and safety equipment required. However, it is important to note that the costs for compliance and licensing fees for both types of extraction businesses can be high in certain states and municipalities.
