Yes Reiko you read right! I like your approach, close the loop!
I think its important to note that when we run rosin we do big runs of high quality flower and we are not looking to extract the load in any one part of the our process. Squishing for yields tends to make us ALL push the materials too hard and you often end up taking much more than rosin out of your plants (we lab tested our product several times and adjusted our outlook accordingly while we were setting up the process) so we take a gentler approach. We intentionally leave a small percentage in the material as to not wring it out.
I will take some pics of the chip bags close up and you will see that because we use material with really high THC we can extract a 25% yield and still have visible frost in the bag. This is to ensure we didn’t over do it. At that point should you have bubble extraction setup and a hand mixer from your kitchen makes this effortless. With de-bagging during pressing, a few minutes of grinding and 20 mins for bubble hash I don’t find it a lot of work and consider it a reward.
As I mentioned before going through this process I had no idea what the buffer was, how efficient my press could be as well as how much it really locked into the pucks. When you are pressing in bigger runs and you know there is 3-5% this can mean a lot of meat on the bone still. I find that we will take an ounce and a half out of bubble hash for every lb we process solely out of materials in the chip bags. The bags themselves as you clearly demonstrated are lil gold mines themselves.
Really appreciate you taking the time and I see your name and you gens all over the forum so keep up the good work!!
