Hello everyone, first off i just want to say thank you and this is an amazing community of people.
I am helping to plan my first lab build out and beginning the consider the actual logistics of moving around solvent and and maintaining temperatures. So far I am planning to store ethanol in a -20C c1d2 walk in freezer and have a -80C chiller for the extraction. My question is should an ethanol tank be used to move the ethanol from the barrel/keg to a tank to chill down to -60 before being introduced to the extractor(planning on CUP 30). It would be trying to run the machine as much as possible in a day. I am considering the use of LN2 or LCO2 but am looking to keep consumables to a minimum. Any and all input is welcome.
100 gal jacketed extraction vessel ($6400 from glacier tanks) hooked up to a chiller (you can fill at the end of the day to let chill overnight) then use inline heat exchanger with additional chiller to maintain temps when you reuse your ethanol.
For more volume double up!
That’s an apples to oranges comparison though. That delta chiller is supposed to be able to cool like 2000 gallons a day. How many chest freezers would it take to do that? The space commitment alone would wreck that option.
