Anybody have an ultrasonic cleaner and some ground coffee?
If a tank of rapidly-vibrating water can break gunk off jewelry, it should be able to extract the goodness from ground coffee, perhaps even from whole beans.
I think an ultrasonic coffee maker would bring out different flavors, perhaps a more mild and less acidic brew. It might just make a slurry out of the grounds, but different frequencies should give varying results. A filter would probably still be needed.
Ultrasound would certainly speed up the brewing process.-- baconbrain, Nov 28 2010 See how effective are the ultrasonic cleaner who are removing gummed model engine. http://www.youtube....watch?v=wOlcxZrdCTQIf it will do this ...

[jutta, Nov 18 2021] Seriously, I would appreciate a test, if anyone has an ultrasonic cleaner tank.-- baconbrain, Nov 28 2010 I'm still working on testing the centrifugal coffee maker (which reminds me...)-- MaxwellBuchanan, Nov 28 2010 // Maplin have an ultrasonic cleaner on offer at the moment. //
Just from the way that sentence is written I can tell I'm on the wrong continent.-- baconbrain, Nov 28 2010 I doubt using whole beans will work. The gunk cleaning mechanism appears to be a surface-active thing. Grounds, maybe.-- daseva, Nov 30 2010 I'm currently running an ultrasonic humidifier in my household at night - we go through about a gallon of water each night.
I wonder if you loaded it with beans and water if it would be down to an espresso analogue in the morning.-- normzone, Nov 30 2010 I don't think a humidifier does the cleaning/extracting aspect that I am after.
But if you loaded your humidifier with already-brewed coffee tonight, you might not need your alarm clock in the morning.-- baconbrain, Dec 01 2010 Maybe a powerful ultrasonic device could break the beans up... This might be a way of getting iced coffee without the intermediate hot step.
By the way, baconbrain, what do you mean by "goodness"? I thought we only drank coffee because of it's "badness"?-- Ling, Dec 01 2010 Coffee can be decaffienated by the use of CO2 by supercritical fluid extraction; the by-product is (durrrr ....) caffeine.
By a clever chemical technique called "mixing", this recovered caffeine could be "added" to unmodified, roasted ground coffee beans. More than sufficient to send you off down the road, twitching, sweating and gibbering (as if anyone would notice the difference).-- 8th of 7, Dec 02 2010 I don't see a dollar amount on one, but Maplin seems proud of the fact it weighs just under 30 pounds.-- baconbrain, Dec 02 2010 But if the coffee's ultrasonic, how can you catch up to it to drink it? Wouldn't you need to have the coffee first?-- Ander, Nov 28 2021 You're thinking of supersonic coffee. Ultrasonic coffee is the one that gives you the shakes in the 20+kHz range.-- pertinax, Nov 28 2021 Good catch, [a1].-- pertinax, May 31 2024 random, halfbakery
