Hi,
I have a 3" slant plate boka with liebig controlled by voltage and output only.
I have done about 20 or so spirit runs and never had a problem except when experimenting/learning on the first few.
Running TPW. About 50/50 copper/stainless packing.
Water flow has not changed, I am not controlling thou.
I started having a problem with the tails coming in too early and too much of it.
The last 2 fresh runs I'm getting tails where there should be only heads.
So I started looking for problems.
I cleaned the copper mesh, no change
Run a citric cleaning run, no change
Replaced some of the copper mesh with new stuff (soaked in heads and then in citric), no change
Replaced all the stainless and old copper mesh for new copper, no change
Soaked the water side of the condensor in vinegar/water in case it had corrosion and was stopping heat transfer, no change
I have tried 3 different stripped runs, no change
I have tried running the power so low I was only just getting output (not good for reflux, but should separate everything), no change
I don't know what else to try. The only weird thing I have noticed is that on the stripping runs the output is slowing before the temp gets as high (95 degrees it never used to slow at all until I shut down at 97 or higher). I'm not controlling by temp but it has always been consistent.
Can anyone help
Thanks
