With the explosion of the cannabis industry, more companies are springing up to meet the ever-advancing needs of growers, producers and consumers.
One company is Sesh Technologies (STM), a Spokane start-up that began when a grower asked friend Jason Dueweke, if he could create something that could press more rosin than what was currently on the market. Dueweke, an engineer who works in the aerospace industry, agreed, made it happen, and STM was born.
But back up a second: What’s rosin?
Rosin is a cannabis extract produced by applying heat and pressure to the marijuana plant or flower using a special press. The result is a translucent amber liquid that some processors compare to shatter, another heat-treated extract. But rosin is produced without the use of solvents, such as butane or carbon dioxide.
When extracted properly, rosin rivals the flavor, potency and yield of shatter and other solvent-based extracts, but contains zero parts per million of any residual hydrocarbons.
Shatter makers typically remove the bulk of any solvents during the production process, but rosin remains naturally clean, a prime selling point for Sesh Technologies’ rosin press.
Another side benefit of using the rosin press is that once the rosin has been extracted, the smashed-down “puck” left behind in the press can be shredded and turned into joints using STM’s RocketBox pre-roll machine. The machine is capable of filing 453 cones in a few minutes. And the extra rosin in the joints can create an even more potent experience for consumers.
Longtime cannabis users may have experienced rosin made with a hair-straightener or something resembling a T-shirt press, but the STM 4.0 Rosin Press goes beyond low-tech solutions.
Dueweke, Chief Operating Officer, created a machine that looks like it would be appropriate for a high-tech electronics factory instead of a cannabis processing line. You can’t even get your hand near the press area without breaking a laser that automatically shuts the machine off.
All STM products are made with commercial grade components, touch-screen controls and stainless steel casings. The platen on the press is made of food-grade stainless steel. All STM processing products are made with materials manufactured in the U.S.
Dueweke said some customers ask if all the commercial safety standards aren’t overkill, but STM is making products for where the industry is going, rather than where the industry is right now.
“Some of the regulation for processing isn’t here right now, but it’s coming,” Dueweke said. “People are handling this stuff around high heat and pressure, and then the final product is injected by humans.”
He believes it’s not a matter of ‘if’ cannabis production will someday be regulated by the state or federal government, but when. At that point, STM products will already have the highest safety standards.
STM has developed an entire branding initiative known as the Clean-Green Cannabis Initiative, which promotes products that use its technology and focuses on using every part of the plant, so no waste or recycling is needed.
Besides Dueweke, company leadership includes co-founders Aaron Ray, CEO, Erik Blackerby, CTO, and three silent partners.
Growers and other producers interested in using the rosin press and the RocketBox might also be interested in the STM mobile processing service. The company’s first fully self-contained mobile processing unit was built on a Kodiak C5500 truck, and contains everything needed to turn cannabis into rosin, joints, or bubble-hash.
The first unit was recently delivered to Colorado, and there are nine more in the works. Though the mobile processing unit began as a side project, it has really taken off recently, and is one of the big ways STM is pushing into many states at once, including Oregon, Arizona, and Florida.
• Cannabis flower is placed into a small compressor called a “pucker” that forms it into the shape of a hockey puck.
• The puck is placed into the rosin press, where heat and pressure are applied, compressing further until rosin fluid oozes out the sides.
• The fluid is collected and put into packaging.
• The spent puck is shredded and made into joints in the RocketBox.
