Different Techniques of Making Solventless Extracts

Solventless Extracts

The equipment for solventless extraction costs less than a third of what solvent-based operation costs. In addition, unlike solvent-based operations, which can quickly rack up start-up costs, solventless processes are flexible and can scale to fit any size facility. And they don’t require the expensive maintenance of a solvent-based operation.

Live Rosin

Bay Area solventless extraction uses no solvents, which preserves the plant’s natural properties. The plant’s original trichomes are preserved, and the resulting product resembles a fresh-frozen cannabis flower. The solventless process can produce a variety of tinctures, edibles, and topicals. Unlike solvent-based extraction, which involves chemical dissolution, solventless extraction involves only mechanical separation.

Solventless extraction is much safer and can save producers thousands of dollars. It can also help prevent overbaking, a common cause of complex hash. Solventless extraction also produces a more terpene profile. Unlike traditional solvent-extraction methods, solventless products tend to have a milder flavor, while the rosin-based process produces a more potent and aromatic effect.

Re-pressing Rosin

Re-pressing rosin aims to extract cannabinoids and terpenes from the trichome glands. The quantity and quality of rosin will depend on various factors, including the pressure and temperature used in pressing. A few tips to maximize the quality of your rosin include pressing cannabis on parchment instead of glass and increasing the pressure while pressing.

One of the benefits of solventless extraction is that it is safer and does not require using any flammable chemicals. Solvents have a significant environmental footprint and may cause lab fires due to user negligence or inadequate ventilation. Another advantage of rosin is that it can be manipulated to produce the texture and consistency you want. Depending on the desired outcome, it can mimic different textures, including wax, crumble, or shatter.

Re-pressing Rosin With Water

The process of making solventless extracts requires meticulous analysis and multi-steps. It is also time-consuming. However, it will result in the best solvent-free concentrates. Therefore, a rosin press capable of finely controlling plate temperatures is ideal. This process involves sifting the hash, which contains vital trichome heads. It is then placed between two plates and placed in filtering bags with tiny holes.

When re-pressing rosin, it is essential to use high-quality cannabis flowers. Using lower-quality flower strains will result in low-quality rosin. Therefore, it is also necessary to use high-quality cannabis flowers, such as fresh frozen flowers. This will enhance the flavor and preserve the mono and sesquiterpene content.

Using Rosin to Create Solventless Extracts

Rosin presses are incredibly easy to use and produce a significant quantity of high-quality extracts in less than an hour. In addition, Rosin presses are more efficient than closed-loop systems, which take months to run and require considerable time and money to operate.

Solventless extracts are becoming more popular with cannabis users. The traditional way of making concentrates was by pressing the cannabis bud with a hand press. However, many of today’s rosin presses are made using solvents. These solvents are often derived from vegetable oil. Although these solvents are considered the safest on the market, they don’t carry the flavor as well as rosin. Moreover, they are much denser than rosin. Nonetheless, they work well together to produce a smoother hit.


There are many safety concerns surrounding solventless extracts, mainly if workers handle them indoors. Employees must be adequately trained and properly equipped to handle dangerous solvents. Proper facility design and fire department regulations can minimize the risk of workplace accidents. A good extraction consultant can help you design a safe facility to reduce exposure to the hazardous substances used in the extraction process.

Another concern about solventless extracts is the presence of residual water activity that may contribute to the growth of microbial colonies. Therefore, solventless extracts should be thoroughly tested before they are sold in the marketplace. This will ensure that their residual water activity is below a level that could cause microbial growth and the development of mycotoxins.
