A smallish tube standing up.
A litltle bit of coffee and a little bit of very hot water is put in. Then from below air is pumped through the mixture causing lots of bubbles. out from the top comes the lovely smell of coffee.
For those who like the smell but not the taste.

FAQ about coffee
http://www.sweetmar...om/caffeineFAQ.html
"Caffeine has a very stable crystalline structure with a boiling point above 600 degrees Fahrenheit" But Wikipedia says it sublimes at 350 F. [ldischler, Aug 24 2006]
Caffeine at Wikipedia
http://en.wikipedia.org/wiki/Caffeine
"May be fatal if inhaled, swallowed, or absorbed through the skin." Yeah, right. [ldischler, Aug 24 2006]

//A smallish tube standing up. A litltle bit of coffee and a little bit of very hot water is put in// sounding awfully like an espresso... |
|
| |
Since you can buy "fresh bread smell", I'll be entirely unsurprised if you can buy spraycans of coffee smell. |
|
| |
I thought this was to be something integrated into alarm clocks. |
|
| |
Although I do love the flavor of coffee, I've once tried roasting coffee beans in the oven, just for the smell; that definitely doesn't work. |
|
| |
//For those who like the smell but not the taste// |
|
| |
[jutta], why did that not work? Roasting beans at home in the oven is commonplace, and although I have never done it, I cannot imagine why a strong coffee smell would not be released. |
|
| |
I've always wanted to roast my own, but if some sort of filthy stank is released then I might just leave it to the experts. |
|
| |
It just smelled burnt, after a while. I'm guessing that I heated it too much, too fast, and that grinding the beans and lower heat would have worked better.
I lived two blocks from a place that roasted their own coffee beans. The smell isn't terrible, but not good in the way freshly made coffee smells good. |
|
| |
I imagine that this would appeal to coffee lovers who have had to eschew coffee for health reasons and must give up their morning java. Just wonder if it would be like smokers trying to quit with multitudes of smokers around them. |
|
| |
This may sound dumb, but the smell of coffee brewing and the smell of flattened skunks (why they choose the main highway as their mating spot escapes me) have always smelled similar to me. Has anyone ever analyzed these two smells to see if there is a commonality there? |
|
| |
Oh, ok, then an extraction column which performs the mass transfer of the volatile molecules of coffee to the air more efficiently. I suspect a greater rate of transfer if you instead electrostatically spray the coffee into a stagnant vessel of air and then release the vessel after spraying. |
|
| |
I once walked past a place that roasted its own coffee. They'd just opened, and they hadn't fitted extractor fans. Suddenly I was enveloped in a thick cloud of white coffee smoke/steam, and got a couple of big lungfuls of the stuff. It may have been my imagination, but I felt fanged allllll night.
Maybe there's an application here for a nasal coffee-bong? |
|

I asked the author of the quoted text in the FAQ that ldischler links to about the difference between his number and the frequently cited sublimation point. He points out that he lists the point of transition from *liquid* to gas, while the sublimation point in Wikipedia is the point of transition from *solid* to gas. (We're used to things going from solid to liquid to gas, but some materials can skip the liquid stage on their surface.) |
|
| |
So, if you were to put a block of caffeine into an oven and slowly increase the temperature, a little would turn into gas at 352F, the rest would melt at 460F, and then, at 600F, the puddle would evaporate. |

an inhaler for that warm coffee smell [+] |

// I'll be entirely unsurprised if you can buy spraycans of coffee smell// Yes but gourmet smelleers want the best, fresh micro-roastery home-ground organic fairtrade small-estate rare variety bean, freshly infused in hot but not boiling water*. |
|
| |
[XXIIQ] I'm sure a drip feeder could be used to keep the water level at the optimal point. |
|
| |
*"Coffee boiled is coffee spoiled" |
|
| |
It seems very odd that liquid caffeine would boil at a temperature so much higher than the sublimation temperature of solid caffeine. Regardless, significant amounts would evaporate at roasting temperatures, vindicating [m Al com]'s experience. |
