Hudson bay distillers Posted September 29, 2018 Share Posted September 29, 2018 good morning does any one know if mashing (malt barley) produces carbon monoxide . here why , our mashtun is pre heated with our hydronic system that brings the mash water up to 140 F , this takes about 6 hours . so last night before leaving we put water and grain in mashtun to pre heat over night expecting to wake up and have 400 gallons of mash almost to temp , inject the rest of the heat and done deal . well at 430 this morning i wake up to the alerts from gas sensors saying there is a carbon monoxide issue . our tun room is air tight with xp ventilation system so i turn it on and in a few min the alerts stop . so question is can the mash tun produce carbon monoxide . this is the first time this has happened so not sure if alarm system is malfunctioning or is there really carbon monoxide being produced some how . im thinking if i put kims cat in there and check on it in half hour i would know if the sensor is lying . tim Link to comment Share on other sites More sharing options...

bluefish_dist Posted September 29, 2018 Share Posted September 29, 2018 FYI the fire department can come out and check with their meter. I think hvac techs also have co meters. Had to have it done at home when a co alarm was going off. Turned out it was bad and was a false alarm. Link to comment Share on other sites More sharing options...
Curators Reserve Posted September 30, 2018 Share Posted September 30, 2018 Further to this - what about Carbon Monoxide from Still Parrot outlet? My Gas/ LEL Meter picks up decent levels that I assume is CO2/ CO off-gas from the Wash degassing in the Boiler during heat-up.. Link to comment Share on other sites More sharing options...
Silk City Distillers Posted September 30, 2018 Share Posted September 30, 2018 Is your hydronic system using a gas fired boiler? Where is the boiler in proximity to the mash room? Why is your mash room air tight? Link to comment Share on other sites More sharing options...
Hudson bay distillers Posted October 1, 2018 Author Share Posted October 1, 2018 silk our hydronic boiler is wood fired and outside in middle of the yard . the sensor has not gone off since it musta bin jus one of those things i guess . tim Link to comment Share on other sites More sharing options...

You will have bacterial fermentation taking place here, probably generating co2. Youll spend lots of time in temp ranges that the lacto and other bacteria on the grain will be very happy in.

Hudson bay distillers Posted October 1, 2018 Author Share Posted October 1, 2018 silk yesterday we changed it up for just that reason , we let the water preheat over night and added the grain in the morning it worked better i think . tim Link to comment Share on other sites More sharing options...
