Rosin processing as increased with popularity for its ease of use. Learn about how they work and the types of rosin processors available.
Rosin has become an increasingly popular technique for processing cannabis, and with it, the advent of rosin presses. These presses provide a way to complete an already simple process, ushering in an alternative method to the lengthy process of producing other materials, such as BHO (butane hash materials).
What Is ROSIN?
Rosin doesn’t refer to a substance, but instead to the process of extracting resinous sap from a starting material. The resin is often translucent and is comparable to shatter or BHO, but without adding any additional processing materials. As a result, it’s safer than other products that combine cannabis with unnatural chemicals.
With cannabis, the rosin process is excellent for both extracting materials from the flowers themselves and for cleaning up kief and hash into a proper hash oil for smoking. Without the need to add any additional chemicals, the rosin process is more straightforward than other lengthier methods that require several steps to make safe consumable products.
Even those without any botanical extraction experience can complete a rosin process without difficulty and still make a BHO-like product with similar results in far less time.
How Does Rosin Work?
The complete rosin process requires three main components: heat, pressure, and time. The simplicity of this means that you can make rosin with a hairdryer, and some heat resistant safety equipment.
When you expose your base material to heat and pressure, it produces resin. Unlike BHO and other products, you only need the base material and the equipment, not any additional chemicals to create a product. Those additional chemicals require a purge to give you a consumable product, while rosin made resin is clean from the get-go.
Beyond just the time and cleanliness benefits, the resin produced from rosin processing is roughly the same as BHO or shatter. The amount of flavor and aroma is near indistinguishable, just without any residual hydrocarbons in the product.
While the simplicity makes it appealing for those who make their products, resins have also become a common item in stock for legal markets.
You may be able to conduct rosin processing with some simple DIY equipment, but that doesn’t mean that technical advances aren’t on the rise. Rosin presses are the next step to producing more substantial amounts of high-quality resin. The market is just in its beginning phases, but the popularity of resin processing is increasing, bringing presses to the forefront.
While a hair dryer can provide the heat and pressure needed for resin production well enough, it still only covers a small amount of area. Rosin presses offer a larger area for base flowers and hash to be put in, meaning you can get a lot more resin without having to clench that hair dryer for too long.
The temperature of your press can affect the resulting resin.
Lower temperatures (from 150°F to 220°F) will provide a resin that has a honey-like substance. Overall, you’ll get less product yield, but have a better flavor and more preserved terpenes and cannabinoids.
Higher temperatures (from 220°F to 250°F) make a more sap-like resin. Using more heat burns up more terpenes and cannabinoids, giving you a less stable product, but there is more yield as a trade-off.
The temperature needed to produce resin varies based on the amount of pressure the press can provide, but there’s not much need for the temperature to exceed 300°F. Rosin presses can give you more precise heat control to get a better quality of the product.
the specific temperature ranges for product results, there are less precise pressure requirements. Reaching around 1333 psi serves as a reliable baseline.
With a resin press, you’ll have far more consistent and better levels of pressure than you would with that DIY hair dryer method.
What To Look For In A Rosin Press
Depending if you’re looking to use your rosin press for personal or commercial use, you’ll want to consider the different parameters in different ways:
Types Of Rosin Presses
Though still considered a newer technology, there is no shortage of variety when it comes to rosin presses. Through combinations of DIY and research efforts, the rosin presses on the market give different options and benefits.
Even with the higher-end presses available, do it yourself presses are still accessible for those who have a tighter budget or want the flexibility of being able to make resin while on the go. The hair dryer method works well almost everywhere, and clamps can help make up for some of the pressure limitations. The limited amount of gear makes for easy transport.
Beyond even that, it’s possible to construct your resin press by combining hydraulic shop presses with heating plates, heaters, and a temperature control system. These are even sold in kits if you’re uncertain of what you might need to assemble. Ten-ton and twenty-ton presses work fine for a DIY model.
It is also possible to modify a hat press into a rosin press. It’s necessary to adjust the hat press to give heat on the top plate instead of just the bottom, but the result is that you can process small quantities of various varieties of rosin. However, they don’t have the pressure capacity to let you use lower temperatures and get higher quality resins, so they’re more suited for personal use.
Manual rosin presses combine the low-cost and transportability of DIY presses, but with higher pressure capabilities. They use a hand crank or twist knob to provide the necessary force to your base material. If you’re not confident in your ability to rig together a DIY model, manual presses give an alternative for home use.
Pneumatic presses pull their compression force from compressed air and can reach up to 2000 psi. It requires an air pump, which reduces transportability, but it does mean you don’t need to hand crank to operate your rosin press. The precise level of temperature and pressure control allows you to make high-quality resin within seconds.
Pneumatic presses can reach higher price ranges since they take a lot of technology and manufacturing to make a high-quality model. Even so, they’re one of the most preferred models due to their reliability and are common on the market.
As one might expect from the name, these presses use hydraulic pressure to provide the necessary force for rosin processing. Ten-ton presses are the most common, readily exceeding 20000 pounds, and there are even twenty- and thirty-ton hydraulic presses as well. The higher pressure rates mean you can drop temperatures into the 100°F range to lose even fewer cannabinoids and terpenes for quality resins.
Since they don’t require an air pump, you will have to use some elbow grease to get them moving, but that does make them easier to transport overall. The more extensive surface area means you can produce more resin as well, making it an excellent choice for even commercial operations.
A great appeal of hydraulic presses is that they’re much cheaper than most pneumatic presses. You can purchase a shop press for a little over 100 dollars, and then modify it with additional parts that cost around $75.
A newer trend in presses, the most significant appeal of electric presses is that you need an outlet and no pumps or cranks to get the pressure you need. You won’t be able to transport it as quickly, but the capability to press up to 15 grams of base flower at 6500-7000 pounds of electric pressure makes up for it.
You can get a ten- or twenty-pound press that’s suited for producing large batches, making them suited for commercial use. If you’re only aiming to create smaller amounts of resin, electric presses also come in models that can provide just the one or two tons of force needed for personal use.
Hybrid rosin presses come with a hydraulic press base. However, instead of being stuck with the hand-pumping method, hybrid presses are built to support both pneumatic and electrical attachments. You can swap out the parts you need for whatever rosin production is best suited for your needs.
These are another rosin press suited for commercial production. They tend to come with larger plates and have a pressure range of 20,000-30,000 pounds.
