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.
See how effective are the ultrasonic cleaner who are removing gummed model engine.

I can't find anything about this device other than this particular PR push, so no idea when, if any, this will hit a market. Especially considering that the anti-oxidant claims directly contradict the paper I linked to above. [jutta, Nov 18 2021]

Seriously, I would appreciate a test, if anyone has an ultrasonic cleaner tank. |
|
| |
I'm still working on testing the centrifugal coffee maker
(which reminds me...) |

// 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. |
|
| |
I doubt using whole beans will work. The gunk
cleaning mechanism appears to be a surface-active
thing. Grounds, maybe. |
|
| |
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. |
|
| |
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. |
|
| |
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"? |
|
| |
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). |
|
| |
I don't see a dollar amount on one, but Maplin seems proud of the fact it weighs just under 30 pounds. |
|
| |
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? |
|
| |
You're thinking of supersonic coffee. Ultrasonic coffee is the
one that gives you the shakes in the 20+kHz range. |
