Rosin comes from an extraction process that uses heat and pressure to squeeze cannabis into a resinous sap. Unlike hydrocarbon extraction methods, it doesn’t use solvents such as butane to help extract the cannabinoids and terpenes.
The major benefits of rosin are the result of not using solvents. First at the production level, there is not an extra step to remove the solvents. There is no need for extensive testing to make sure that all solvents have been extracted from the final product.
At the consumer level, there are no chemical additives, which is a major plus for medical patients seeking a clean, natural product. There is also the full spectrum benefit, in that the rosin retains all of its cannabinoids and terpenes.
Full spectrum extracts are concentrates that are as close to the full cannabinoid, flavonoid, and terpene profile of the raw cannabis plant as possible, yet also removing undesirable compounds such as chlorophyll, fats, and lipids. Preserving as many cannabinoids as possible helps create the “entourage effect”, where the compounds work synergistically together when consumed for a better experience.
The trick to filling cartridges and other devices with full spectrum oil or rosin is to get the temperature right. The oil can crystallize if it is overheated, but will be too stiff and difficult to work with if it is not warmed enough. We have addressed this concern with an update to our CFS-1000 filling machine. We have upgraded the motor so that it can push oil more efficiently at lower temperatures. This increased force from the pump motor pushes the oil as well as if it is being heated at a higher temperature, without the risk of crystallization.
In addition to the stronger motor, we also can customize any tooling for our machines so that our customers have exactly what they need for filling their cartridges and other devices. If you need something specific, we are happy to help build it for you. Reach out to us by phone at 480-993-8446 or by email at Jim@credencefillingsystems.com. We make sure that you fill it right the first time.
