I love the rubber stopper thing in the bottom of the wiper lol. I would make fun of it more if it wasn’t something that I would plausibly do in a pinch
Edit: someone also needs to joke about summit having one that makes the coffee 30x as fast
The evap looks like where the coffee beans are. So… water in the boiling flask, evaporate up the allihn condenser, drip into the evap containing the coffee grounds, collect the coffee “crude” … then what? Purifying the coffee solution would be my best guess for post “first collection”.
I’ve been wanting to make something that can carbonate/nitro charge coffee with CLS parts. You can get sanitary brewing kettles for a decent price online from the brewery spots, or put a chiller that has some spare time to use to keep a cold brew going under vacuum/inert
Add in some staged filtration and the fittings to push with nitrogen plus a pour spout, and you’ve got a needlessly complex coffee maker that you can control almost every variable of
The breaking bad coffee maker actually makes terrible coffee,
If you are interested in a coffee extraction that is truly sophisticated and can be DIY produced via a sep funnel, a BĂĽchner flask and some knowledge of percolation- look into Yama style slow drip coffee.
It’s a form of cold brew that is made via percolation- that is- a Chinese torture style drop by drop saturation of the mark and yields a completely different product from traditional cold brews
Yama cold brew is like champagne while traditional steeped cold brews are more like port or sherry.
Recreating gales rig will likely not yield anything at all that could be considered coffee
Which one can already see by inspecting the setup, which is connected in a way that totally doesn’t make any sense. Starts with the bottom left - vac outlet of the suction flask is connected to the cooling water side of the condenser above it.
btw that “distillation head” is just a fixed volume measuring device (much like a pipette) and the supposed “wiped film evaporator” is nothing but a silvered distillation column. then on the far right, to top it all off, that “chromatography column” is a standard dropping funnel.
Yeah, it’s a movie prop
Doesn’t mean we can’t make something dope that may actually work. Trying to make something dope for my guys in the break room alright. And possibly have some fire coffee too.
While we touch this subject of refining coffee. I was in a Chem lab supply store a while back. I had struck a conversation with the guys there about adsorbents the beginning stages of crc days. The guys dad was old as hell and he went on about a professor he had way back when. This dude was f00king old, too. If he had a professor at the age of 20, it would have been at least more than 60 years ago. I would be surprised if he was younger than 80. But. His professor used start the lecture with pouring his coffee over some form of filter bed/column. And his coffee would come out clear and have zero color. There’s a method to use agar to polish the coffee, but it doesn’t quite make it clear. I also stumbled upon a company that is making a clear coffee now
