I’m currently running room temp and have been getting a ton of gums and undesirables in my extract also I don’t think I’m picking up as much thc as I should be. I’ve been looking into chilling but until I’m ready to make that 60-80,000$ investment I would love to hear ideas on how to get this done in the meantime keeping in mind that my cup system can only handle -40 degrees at coldest. Also I have 3 large Cryo freezers at my disposal that I’m currently using for post extraction winterization. Any thoughts or ideas are always appreciated.
Dry ice and a good thermometer
If You only Ad the dry ice needed to get to -40C
I would recomend the smallest size pellets for this
The freezer can get You a long way
Cool everything down to -50 C and extract the -10c degrees You Will loose as soon as iT all hits the cup
Vacuumbag freeze your biomass also at -50C
no, it has no pockets. You could get a heat exchanger and a pump, or add ln2 direct for chilling. The thing is basically a blanket that you would use at a party for a pre chilled keg.
If you wanted to go baller in a budget @StoneD made a plywood jacket for dry ice pellets a while ago. build a plywood box, line it with R-Tech insulation. Put your keg in there and secure it with braces at the base so the keg can’t slide around. Make a foam lid with a sheetrock knife that goes around the keg top onto the box.
If your small scale and have open top vessels just add it directally to the solvent. Pumps get tricky the colder you go, @cyclopath has been selecting pumps for his operation. Mabey he can chime in if he found a winner chicken dinner.

Made the insulation sleave today the geurilla. Way but iT works so
Some carton used by painters and plaster men
Some good old duck tape
WD 40 and construction foam

What you can do is insulate the outside, and direct cool by injecting ln2 down the dip tube at a slow rate and venting the top of the vessel to the atmosphere for cool down. Once your desired temp is acheived you can use a valve mantifold to pressurize the headspace of the tank by spiking it with n2 gas and forcing the liquid out of the diptube to your extraction vessel. Your ln2 tank will have 2 outputs, there should be one labled gas, and another labled liquid.
If starting out chilling to -50 in a freezer would be enough to run a cup system at the desired -40 temp for the cold extraction and also having your biomass freeze to the -50 then what would be the rate at which it would warm up given a lab room temp of mid to high 60’s? Would it lose anynore thqn 10 degrees in a matter of 15 min?
