Are you filtering up through that by putting pressure into the tank?
Nice I like it. I have 3 in lines as of now
I really like this idea. I assume your using a ULT freezer. How does it stay between -80c - 70c with being open while filtering ? Or do you close the freezer while it is filtering ? When our ULT freezer door is open it gets hot quickly. Love this idea and thanks for any info !!
Most of the filter is outside the freezer, and the doors should be closed. The upright was a -20C, and all I had available at the time. Worked great when the filter didn’t clog. Which it didn’t with stainless scrubbies in the freezer as the first cut. But getting those clean wasn’t a task I managed to delegate. so I got a better freezer.
One very carefully puts holes in the freezer.
Or makes holes in the doors, which don’t have coils, and only sometimes have electrickery in them.

The bucket that I use works great. I’ve used it for about a year straight. I use bubble bags for my biomass. I built a push cart that I plumed 3/4 pipe so when cold extracting the “slush” it flows into 2 step down filters and into a 5gallon glass carboy. Then with my bags that are still saturated with ethanol I put into a panda spinner and retrieve the rest of my ethanol. Much cheaper then other systems out there.

It handles cold pretty well. Doesn’t crack or anything like that. It was a much cheaper alternative for me then other systems prebuilt.

Not me using it. @Akoyeh
Same parts and concept.
Different space time co-ordinates.
It works under +/- pressure.
15psi PRV, so usually vac.
Was set up for vac in this case
Edit: because I insisted the prv be directly on the keg, it faces the floor in this implementation.
Bug? Feature? Probably…
I’m playing with hdpe at -70 tomorrow.
Will try kicking bucket.

Depending on what we are filtering and through what medium dictates whether we use vacuum or nitrogen to push. Works great for both.
turns out there is data on this bucket kicking stuff…

make sure to film this scientific experiment! lol
yeah, I chickened out on taking my steelcaps to a 55gal HDPE drum with tincture at -50…(interwebs suggest I could have gotten away with that…)
I also wasn’t able to achieve -70C on my tincture that day…cheaped out on dryice.
given the null hypothesis that it would drop >$20k worth of cannabinoids on the floor, I decided to try something with less financial risk 
I’ll get back with data when I have it.

lol ya i dont think i would test out the strength of a zubzero hdpe bucket filled with tincture. hell i wouldnt even test it filled with ethanol, 55g of 190 proof isnt cheap either

does aluminum dissolve in ethanol?
They have a reaction to each other. Stainless steel

what im going with aswell.
Are u missing not having a drain? i could have them put on a ball valve for me, but costs 80$ on top of price for them to do.
looking in to these thermo too. Thermo-containers for food
Nope
I use a sauce pan to scoop out wash, pour into readied panda, run. Repeat.

Will take same route, worth to buy a thermo pot you think?
got 2 pandas on the way aswell from the china manufacturer… 430$ shipped fck me…
Apperently they already make a panda spout for adding a hose, also working on a new version of panda.

Be very verg carefull with adding hoses to panda s
If any thing happens and the panda starts flooding the solvent will go straight in the motor
One of the few modifications i never applied for this reason
