Sir, are you making liquor with that cannabis juice?
Actually the frozen fresh hemp is an interesting concept. We havenāt duplicated this test but are told some are flash freezing the fresh material and getting as high as 75% of the water by weight out of the material. I beieve this was just a flash freeze with nitrogen and then its pressed at ambient though. Iām not certain if they press it in a frozen state but that extreme cold breaks open some molecularily bound cell walls allowing more water to be pressed out. This is the type of detailed data we arenāt really being fed back but we know the concept of freezing plants does break open cell walls that wonāt break open at ambient so its logical.
If we press fresh hemp between 75%-82% moisture we get around 50% by weight out which brings the moisture content into the higher 50ās%. When we duplicated this test we got the exact results we were being told from our customers. 0.5% CBD (mainly CBD-A) coming out in the press liquor. 7.5% by weight in Sugars (this is a lot). Less Chlorophyll to deal with on the back end since a lot presses out up front.
Screw presses before a dryer isnāt new to us. We used to MFG dryers and were putting presses in front of them in the energy crisis in the 70ās.
As for the back end and pressing below freezing point of water we donāt have any test results back but Iām pretty certain less of the undesireables will make their way into the press liquor at that cold of a temp. I do believe many if not most are doing it at below freezing temps. The mixture of ethanol acts as a lubricant with the ice so it shouldnāt cause an issue in the press.
freeze, thaw, squeeze, dry
or for those in more norther climes freeze, harvest, squeeze ?!?
Correct. 7.5% sugar by weight.
Our basic math per 1000 acres (we have an excel spreadsheet you can punch in fuel costs and get the rough savings):
Reduces Dryer Fuel Costs: $130,000 / 1000 acres Natural Gas or
$365,000 / 1000 per acre for Propane
Preserves Terpenes by Minimizing Thermal Exposure / Dryer Time
Minimal CBD / THC in Existing water. Cannabinoids Only Oil Soluble. Max 0.5% CBD (we have a COA for this test)
now those fuel costs make more sense than what my memory was telling me after MjBiz! Thx for that clarification, cause I was skeptical on saving 100K/acre in fuel LOL!
I did experiments running fresh frozen and blasting with LN first then running -80 EToH. Gotta wait till next season to try wet but should have no issues.
Proof tested the ethanol after we reclaimed from the FFE and it was 200 proof
Had two Vincent CP-6 working in this exact system. (Iām now out of the game)
