Storm King Distilling Co. Posted February 24, 2018 Share Posted February 24, 2018 Yesterday we fired up our still for the first time (200gal of 9.5% fermented agave) and went to work. For nearly 5 hours the kettle temp (182F), the dephlegmator temp (164.8F) and the condenser temp (162.5F) all held constant. Then out of no where a weird thing started happening. The still temp rose to 190F and then held there. When that happened our dephlegmator and condenser started to do this dance where the temp on the condenser would go up to 170F, but the dephlegmator temp would be in the mid 160s. THen the condensor temp would start to fall and the dephlegmator temp would rise. This continued until we stopped operation for the evening, about 2 hours. Any one have an idea as to why? We made no adjustments to anything when this started...soon as we noticed it we tried adjusting input and output on the dephlegmator to try and get the temps to settle, this just made the swings worse. After about an hour of messing with it, we put everything back to where it was and this little rhythm started and was very predictible, just not what we thought was supposed to happen. We have a pot still with 4 plate column on a stand next to the still, and then condenser next to that, all in line. This is our first time using a column and dephlegmator so we are sure we may not be controlling it correctly. We assumed that once we set everything so that we were getting a constant flow and stable temps, that it would work like a pot still, where the temp gradually increases and the proof decreases over time, without any adjustments to heat or cooling (this is what all our previous experiences with a pot still were like). Any feedback or insights would be greatly appreciated. Oh yeah, we are 100% manual control now. No automation at all. Link to comment Share on other sites More sharing options...
