Do you want to produce high-quality rosin, or get higher yields of rosin? You want to get the best rosin possible from your rosin presses. We’ve listed below our top tips on how to make the highest quality rosin and get the highest yields.
Let’s first review the basics. Rosin is a concentrated extract made by heating and pressing a small amount of plant material so that desired components are forced to the surface in the form of a thick “rosin.” You can make rosin from flower, dry sift, or other harvest materials using a rosin press in NZ.
The use of solvents can alter the taste and quality of rosin, and this is why consumers prefer to make rosin without them. Consumers who do not want to use chemicals or residuals in their concentrates prefer to make rosin using heat and pressure.
Heat and pressure extraction is a method that has been around for thousands of year to produce products we use every day. Solvent less rosin extracts are used to produce concentrated concentrates when squeezing olive oil for olive oil, or grape juice for wine.
Beginners to the world rosin-making quickly want to move beyond the inconsistency of the finished product that is often produced with a flat iron or hair straightener. Next, you’ll need to purchase a rosin pressing. This will lead to many questions, such as “What is the best material, humidity, temperature and time to produce high-quality, high-quality rosin?”. We can help.
6 Tips For Making High-Quality Rosin
Below are six tips for you, rosin producers!
- Best Materials
- Best Humidity
- Best Temperature
- Best Micron Bags
- Best Pressure
- Best Cool Down
Select The Best Materials
The quality and freshness with which you begin your rosin-making process will determine the final quality. It is important to keep in mind that when you use high quality materials to make rosin, you are more likely to obtain high quality rosin.
The quality of the input will determine the quality of the output.
Freshness is another factor that affects quality. You’ll usually get the best results if you press flower as soon as it has been dried and cured. You will get darker rosin if you wait too long. So, press your flower as soon as it is possible.
The growing medium is less important than how well the plants are cared for throughout their growth and blooming cycle. There is no discernible difference between flower rosin produced by plants grown in soil or hydro. However, some strains of plants and varieties produce more flowers that can be used to make high-yielding rosin.
Use strains known for their potency in order to get more yellow rosin leaking onto your parchment.
Choose The Best Humidity
For those who are new to pressing, it’s not uncommon for them to have low yields or lower-quality rosin due to their plant or flower material being too dry. Too dry plant material acts as a sponge and absorbs the rosin that you are trying to extract. If the plant material is too dry, the trichomes will be absorbed into the plant material rather than flowing onto the collection pad or parchment.
Recommended Humidity
How dry is it to make rosin? Or, how can you determine the ideal humidity for pressing rosin? We’re talking here about the moisture and humidity content of your plant or flower material. For best results, the relative humidity of the plant or flower material that you plan to press into rosin is between 55% and 62%.
How can you measure the relative humidity in your source material or product? For best results, we recommend investing in a digital hygrometer. Pre-set humidifier packs will quickly and easily increase the moisture of your flowers to between 55% and 62%. The moisture content will have a significant impact on the yield of each press.
Select The Best Temperature
Temperature and time are critical to getting the best results when pressing rosin. They are also the most discussed and debated factors when it comes to rosin production. Finding the perfect combination of temperature and timing is an art form. Some prefer to press the flower at low temperatures and slowly, while others insist on pressing the flower quickly and at high temperatures. Understanding how temperature and timing affect the yield and quality of rosin, is crucial to improving its quality.
The speed and consistency of trichome liquification will be determined by the amount of heat and pressurized plates applied to the plant material. Some prefer a cold press method, while others prefer a hot press method.
Cold Pressing Method
Press between 160degF/71degC and 190degF/87degC at 1-5 minutes. It produces a thick batter-like consistency, with good terpene retention, but lower yields have been reported.
Hot Pressing Method
Press between 190degF/87degC and 220degF/104degC at 45 seconds to 3 minutes. This method produces a product with an oily or shatter consistency. At 220degF and below, terpenes are preserved well. Yields can be higher than cold pressing.
(Note that above 235degF there is a more significant and noticeable loss of flavor and terpines.) Note that terpines and flavor are lost at temperatures above 235degF.
These guidelines will help you choose the best method for your situation.
Choose The Best Micron Bags
Most rosin producers use filters or rosin bags when extracting with a press to avoid small plant fragments getting into the final product. There is no single rosin bag that works for all purposes. You want to maximize quality and quantity. Choosing the correct micron is important for obtaining the best rosin.
Remember that the smaller holes (25u or smaller) in rosin filters bags allow more plant material to pass through. The larger the holes (such as 220u) the larger they are.
Filter Bag Size
You have to decide how much plant matter you want in the rosin. If you’re primarily concerned with maximizing your yields and don’t care about small amounts of plant matter in your rosin or extract, then use a larger micron size. If you want to create the purest and clearest rosin, or extract, and value quality over quantity then a smaller micron size will be the best choice. Use bags that have a micron between the two sizes for a balanced approach.
We recommend 90 micron filters bags for pressing flowers. Bags with smaller holes will negatively affect yields and have negligible improvements in quality. If you want to focus on quality, but are willing to sacrifice some yield when pressing flower, then 90 micron filters bags are the best choice.
Filter bags larger than 120-160 microns can cause a loss of quality and purity, since unwanted material may pass through the screen. We have found that filters between 90-120 microns are a good compromise between yield and quality when pressing flower rosin.
It is important to consider the materials used to make the rosin press bags. Different materials react differently to heat and pressure. Food grade nylon is the material that performs consistently and most durably under most rosin pressing situations.
Choose The Best pressure
It’s a commonly held belief that more pressure is better when making rosin or other extractions. This has been proven to be untrue. It was once believed that a large rosin presses that could deliver industrial PSI would be required to produce high-quality rosin. It is true that having a bigger rosin presses will allow you to produce more rosin per press. However, this is not the only way to get the best rosin.
Applying the right amount pressure is tricky, just like temperature and time. If you apply too little pressure, it will not be enough to separate the oils. Applying too much pressure can cause a blow out where plant material is leached into your concentrate. For flower rosin it is best to use pressures between 550 psi and 1500 psi, with the highest quality at the lower end.
Recommended pressure
Remember that ideal PSI is between 300 and 1000. For flower, you will need more pressure and for products like dry sift or similar products less.
Recommended PSI for Dry Kief/Sift: 400-800 psi
Recommended PSI for Flowers: 600-1000 psi
The formula below can be used to determine the PSI value or your ideal rosin pressing pressure. This example shows that 1100 PSI is the platen PSI. It was calculated by dividing the total press power in pounds (20000) by the total area of the pressing bag (3″ x 6″, 18sq.in.). ).
Formula
PSI = Power of Pressing / Pressing Area
1100 PSI = 20000 / 18 sq. in.
This formula shows that we will need a rosin pressing machine capable of applying ten tons in order to achieve the desired pressure (20,000 pounds = ten tons). Who would have thought rosin pressing required math?
Choose The Best Cooldown
Stabilizing our rosin at a cold temperature is the final step in optimizing your rosin-making process. This will ensure that you get the purest, highest quality rosin. Rosin is composed of volatile oils which can degrade quickly. It’s therefore important to preserve these oils once they have been extracted.
Freezer Method
This can be done by placing your newly extracted rosin on parchment paper and freezing it for 10 to 15 seconds. The short time spent in your freezer will be enough to stabilize the rosin. This method is particularly effective if you have rosin that has a liquid consistency. By putting your rosin in the freezer for a few seconds, you can increase its lifespan and reduce volatility when it comes in contact with air.
Cold Plate Technique
Use a cool plate underneath the parchment paper to help preserve the precious oils in your rosin and to make it easier to remove it from the rosin presses. After rosin is extracted, remove the plate from the fridge and immediately place it over the fresh rosin. Cooler temperatures will help separate the wax from the silicone-coated parchment, and also prevent your hands from becoming too hot when you break off chunks of the wax with your fingers. Peel off baggie carefully and secure jar lid before stamping each piece of material collected into its own space within container to avoid mixing flavors again.
Conclusion
The collective knowledge of our community continues to grow and accelerate as we continue to learn about this exciting extraction method. The constant innovation and experimentation that’s happening in this field is exciting and surprising.
