Second run (w/ Fractional Reflux operation instructions)

Post by leeb72 »

I just finished my second run. Started with 7gals of ujsm and I have a question? My first run was the same but just a shake down run I returned all the first distill to the second run (almost all). I held my ½ Keg boiler at 165 deg for 30 minutes and the column (reflux 2inch x 3 foot with offset 15inch condenser) never got above 110 deg. So I slowly raised the temp in the boiler to 180 deg. And the temp in the column came up to 150-165 deg at the condenser I took about a half cup off at full strip, then at 170-175 deg I let it run full reflux for 1 hour after. Did I go too fast and should I wait to see if the column temp would come up at 165 boiler temp? I was trying to use temp control to cut the heads and tails? I collected at 170 – 190 deg until it slowed way down then kicked it up to 198 – 200 to collect and finish the Tails.
Am I close?
