Boredom Design/Open Source , Ethanol and Dry Ice based Chiller

So I was thinking what if there was a way to make a like a freezing ethanol pump that has like a dry ice pulverizer and chute on the side that can pulverize bricks or pellets into metered amounts.

The pulverized dry iced would go into a chamber that holds ethanol that has high pressure seals and are chemical reisstant. The exuast from that chamber would be read out on a gauge that shows it’s being balanced by a PRV and Pressure regulation System that’s built in.

Once the Ethanol becomes a freezing fluid and the pressure becomes stable a spark free, explosion proof, chemical resistant transfer pump starts up. The pressure safely gets built to 30 psi on the transfer pump which then sends the freezing fluid through whatever jacket you’re using.

Then the freezing fluid gets transferred back into a storage tank within the unit by means of suction from another explosion proof, spark free, chemical resistant transfer pump but low psi as to not cause flow issues. Once the tank is 3/4 way full the user is then encouraged to add more dry ice to the pulzerizer and release the returned ethanol an the whole thing starts over again.

Crude idea but I think it’s neat. Think of this as the Ethos of chiller ideas lmfao.

Another Idea was to have the pressure and the vapors from the dry ice and ethanol some how be able to power the flow of the freezing ethanol while having some kind of safe return and then once that natural pressure is done then the transfer pump does the rest of the work. The return line off the jacket and into the chiller would just be normal pressure from the chiller to move the freezing fluid into a recirculation chamber which also has a dry ice chamber … The vapors would naturally be exhausted or a PRV would be implemented.

drop the pressure seals. run vessels at zero PSI. simplifies all your controls.

the dry ice is gonna screw with your ph, also dry ice is kinda dirty…

It’s not an extractor it’s a chiller the pH doesn’t matter.
