Thinking about pressing sugar leaf and kief. Would like to know what kind of yield can be expected from each and also best press configuration - plate type & size?
I’m not experienced in rosin pressing, but I would like to learn more as well.
Adding onto your question, what companies are making the best quality rosin presses out there? Which companies are most popular and why?
@tasiakelle Do you use Rosin presses?
Nate, I’ll Let you know how it goes. We are purchasing a Sasquash Press this week and will be giving it a shot.
Looking forward to hearing how it goes. Post some pictures once you’ve had a chance to try it out!
We got the Sasquash in today. Will keep you posted on how the pressing goes!
That is a nice looking machine! How much force does it exert to press the rosin?
What pore sizes do you use?
Thanks Nicholas. From the information that I have gathered, you want to
pre-press at 10 to 15 psi and increase up to 110 - 115 psi. I’m sure that
different material i.e.; flower / kief reacts differently to temperature
and pressure. Here comes the learning curve! I’ll keep you posted.
We are going to use 35mu bags for our kief and 120mu bags for our flower. Pressing today!
Best of luck and let us know how it turns out.
Update on the rosin pressing - we pressed 8 bags of “A” bud flower, (each weighing 14g) and 2 bags of kief, (one bag weighing 10g and one weighing 2g). We varied temperature from 190 to 220 degrees f and pressing time from 45 sec. to 4 min. Our “sweet spot” on flower seemed to be at 220 degrees for 2 1/2 min.
Our over all yield on the flower was lower than we had hoped at 12% but the solvent less rosin that we produced is absolutely gorgeous and we will get better. Attached is a pic of the final product.
That looks beautiful! How did the kief perform vs the flower?
Our first kief run was a disaster! We blew the bag out on the 10g run. The 2g run worked much better with a yield of about 70%. Both were pressed at 190 degrees for 1 min. Pained me to see 10g of kief ruined in 60 seconds!
Ouch. I feel your pain.
Here is a link to a short video of 1 of our flower presses from yesterday
Thanks so much for getting back to us with detailed feedback! How you feeling about the Sasquatch post purchase?
Thanks for posting the photo and video. Glad that the second run came out better! It sounds like the machine is fairly noisy from the video. Is it bad enough that you’d want to wear earplugs if you were doing it for an extended period?
We purchased the Sasquash used and it is the V1 so it is exactly as expected. I think the pressing technology, as with most things in this industry, is changing rapidly. If we can determine that consistent yields are obtainable and if we see a good market for our rosin I think we will be looking to upgrade our press in the future. If money were no object and I could’ve purchased any press out there I would have likely gone with Pikes Peak Pure Pressure. Maybe we need to do a Growers House Review?
