How much pressure do you need for rosin?
How much pressure does a rosin press need?:
It's important to remember that the number to focus on is Platen PSI, not general pressure/force. The general consensus among the industry for full yield capability at lower temperatures is:
Flower rosin: 1,200-2,500 Platen PSI
Hash rosin: 700-2,000 Platen PSI
Any higher Platen PSI will result in unnecessary torn bags, parchment, closing of oil channels, etc. Any lower Platen PSI will result in loss in yields and higher temperatures required for a full extraction.
The pressure needed will depend on the temps you use, but, also on what you're pressing.
Flower needs more pressure, somewhere between 600-1000 PSI.
Dry sift/kief or hash will require less pressure because it is more concentrated. You should shoot for between 300-800 PSI.
Too much pressure can lead to a lower quality yield. You can actually end up squeezing plant matter into the rosin, resulting in impurities, poor taste, and overall lower quality.
How to calculate Platen PSI for your Rosin Press:
Platen PSI is simply calculated by taking the total force and dividing it by the size of your bag, not the size of your plates. In this instance, we'll say you are maxing out our 4x7 V2 Lowtemp Press (20 ton capable) with a 3"x6" bag of material. For round numbers, we'll say you're utilizing half of what the cylinder can generate: 10 tons (2,000lbs per ton), or 20,000 lbs of force.
3"x6" pouch= 18 square inches
10 tons of force= 20,000lbs of force
20,000 lbs / 18 sq in = 1,111 Platen PSI
The Best Rosin Press
The Sasquash M2.5 Rosin Press
On top of having one of the best names, the Sasquash V2.0 can press up to two ounces of flower at once!
It features huge 10" x 5" dual heated plates, and provides over 25 tons (10,000 psi) of pressure.
This is a hydraulic press, but can be used with a hand pump, electronically, or pneumatically with an air compressor.
This unit quite a bit larger than what would typically be used in a home, weighing in at 170lbs.
The NugSmasher Mini 2 Ton Manual Rosin Press
At just $496, this press is a steal. It is perfect for home users just getting started with extraction.
You can press a ⅛ (3.5 grams) at a time with the 2.5" dual heated plates.
The NugSmasher Mini may be small, but it can still produce up to 2 tons of pressure!
As with all NugSmasher rosin presses, this one is plug and play, features American steel and aluminum construction, and circuit protection.
The Pure Pressure Longs Peak
This mammoth of a rosin press can press out 35 grams at once! It features Ultra-premium 10" x 3" heated plates that not only produce quantity, but QUALITY.
This machine has the option of upgrading to automated pressure control, resulting in even less work on your end.
This unit checks all the boxes we look for in a great rosin press - high quality, rectangular plates with even heat distribution, automation, and flexibiliy. It even comes with a solid warranty, which at that price tag, is important.
Another awesome pneumatic press is the PurePressure Pikes Peak, a slightly toned down version of the Longs Peak.
