Commonly Asked Questions About Dry-Sift

What is Dry Sift?
Dry sift or kief is the result of mechanically removing the resin glands from the plant by sieving them with screens of different sizes, without any kind of solvent.
Dry Ice or Frozen Material?
Freeze your material!! With dry ice you are adding a solvent to your material. We recommend you freeze material, overnight if possible, which will make tricomes harden and greatly improve your yield. We also recommend shorter run times in a cool room, to prevent condensation.
What Micron Screen Should I Pick?
This is dependent on your personal preference and intended use of the sift. The Pollen Masters come standard with 150 Micron Screen, this is the ideal screen for achieving a balance of quality and quantity of Dry Sift and if you are looking for a higher quality, we offer the finer 125 Micron Screen. If your goal is a higher yield, we offer our 185 Micron Screen.
Can I make Rosin from Dry-Sift?
Absolutely. Dry-Sift Rosin its a great way to make a dabbable concentrate, free from solvents. Many customers will purchase a tumbler and a press and use it to process all their trim into rosin. When pressing Dry Sift, we recommend using our 25u, 45u or 73u Rosin Tech Filter Bags.
How long should I run my PollenMaster?
We recommend running the Pollen Master in 15 minutes intervals. After 15 minutes, stop the machine, remove your drum and collect your ‘Grade-A’ Dry Sift. Then repeat this process and keep your ‘Grade-B’ Dry Sift in a separate collection container. After that you can run the machine for another 30 minutes or as long as your prefer. This is your Grade-C Dry Sift, but you may run the risk of getting some plant material in your drysift. It depends what you’re looking for Quantity or Quality.
What can I do with Dry-Sift?
You can sell it, smoke it, pair it with flower, or use it to make edibles, hash or rosin.
Can I choose multiple mcron screen sizes?

Yes, we offer Extra Drums that come in 3 different sizes (125u,150u* and 185u) for easily switching out drums on your Pollen Master. We also offer Replacement Screens that you come in all 3 sizes (125u,150u* and 185u) that you can change out yourself or, for a small fee, we will change them out for you.**

Pollen Masters get the Soil King stamp of approval! I like them so much I started selling them at The Soil King Garden Center. Up here in NorCal we recommend the 1500 or 4500 model to process large amounts of material. Time-tested, nothing works better than a Pollen Master!

Pollen Masters are Rad! I love my 4500 and use it all the time. I tried a couple different machines, but I get the best results with my Pollen Master. At SLOgrown we’re big on organic flower and solventless extracts, so we use Solventless Dry Sift to make some amazing Rosin, Edibles, Tinctures, Salves and Capsules

As the lead extraction artist for a succesful company I had 5 Pollen Master 4500’s and 5 Rosin Tech Presses. That was all I needed to be a top producer of concentrates. I would collect my Grade-A and Grade-B Dry Sift for the High Quality Rosin and then I’d run it all night to make Dry Sift for my edible line.

I have a couple plants at home that I use to make CBD oil for sick kids in my community. Pollen Master made the whole process much easier.
