CO In Your Coffee? : Weird Space Hazards - Vol. 1
"Carbon Monoxide Release from Whole Bean Roasted Coffee in Storage"
McCarrick Letter Neal Jul-2019 Abstract: Industrial coffee producers have experienced a few hazardous events involving carbon monoxide poisoning of employees working in enclosed spaces where roasted coffee has previously been. Coffee stored in flexible bags are fitted with vent valves allowing the off-gassing carbon dioxide to escape without stressing the bag and without allowing oxygen to enter causing degradation of the beans. What has not been considered until recently is the presence of carbon monoxide at much lower levels along with the carbon dioxide. The Naval Surface Warfare Center Philadelphia Division has worked with a coffee producer to quantify the carbon monoxide release from freshly roasted beans. The levels of carbon monoxide in an enclosed space can easily reach toxic levels in a modest amount of time. Reasonable precautions are necessary to prevent accidental harm to people working in enclosed spaces where coffee is roasted or stored. https://ttu-ir.tdl.org/handle/2346/84940 |

"Carbon Monoxide Release from Whole Bean Roasted Coffee in Storage" Would the station have whole beans that are grinded in the ISS or would the ISS only get a supply of ground coffee? Grind beans in 0g? Would it be correct ro state that ground coffee would release its CO during the grinding process? or would the ground coffee continue to release CO? Does the ISS ECLSS have the ability to filter CO out? (do the filters to take CO2 out also filter out CO ? |

CO In Your Coffee? : Weird Space Hazards - Vol. 1
Greetings,
I fully expect that the poor souls on ISS and most near-term future space missions will be forced to consume instant coffee. A few grams of dehydrated coffee per serving is much less mass to deliver than the whole beans or even ground coffee, and the machinery needed to turn it into coffee is considerably lighter and simpler. I seem to remember reading/hearing of astronauts making their coffee / tea with the water straight coming from the fuel cells, i.e. the fuel cell water was the right temperature for coffee/tea. The thought of months or years without real coffee makes me tremble. I have finally found a reason why I wouldn't volunteer for the space mission if asked. Such are the sacrifices for working in space, and I'm pretty sure I'm not psychologically ready for that sacrifice. Regards Frank |

Hi all Should have googled before I replied: https://en.wikipedia.org/wiki/ISSpresso An Esspresso machine is aboard ISS. That will make life aboard the space station practically bearable for any civilized person. Regards Frank |

By Shannon Sweeney - Jun 05, 2018 https://www.deathwishcoffee.com/blog...s-drink-coffee I seem to remember reading/hearing of astronauts making their coffee / tea with the water straight coming from the fuel cells, i.e. the fuel cell water was the right temperature for coffee/tea. That would have been on the space shuttle, or earlier, NASA spacecraft. ISS certainly doesn't use fuel cells for power. That said, it's not too hard to safely heat water for coffee or other purposes in microgravity. The thought of months or years without real coffee makes me tremble. I have finally found a reason why I wouldn't volunteer for the space mission if asked. Instant coffee isn't that bad, IMHO. I've been on plenty of trips where my own supply of instant coffee was all I had. I lived. Such are the sacrifices for working in space, and I'm pretty sure I'm not psychologically ready for that sacrifice. LOL. We've all got to have our priorities. To me, space travel would be like camping. I'm willing to give up some creature comforts in order to make the trip. Jeff -- All opinions posted by me on Usenet News are mine, and mine alone.
