One of the brew pals built a big kettle for our group of 4-6 garage brewers.
20" dialmeter x 36". stainless steel. Approximately 46 gallons to the top.
We noticed a problem during the first boil.of about 40 gallons.
It was impossible to maintain a steady boil.
With a nice healthy flame, the boil would rise up very energetically and cycle back down to nothing. After a time of 45 seconds, the boil would return and shortly thereafter subside. On and on.
It has us confused as to what is taking place and also searching for a solution. Towards the end of the boil, the immersion chiller was lowered in place and it seemed to minimize the cycling after the wort returned to boiling temp.
Thinking of dropping a large stainless funnel upside down with a ss pipe venting partially to the top of the wort.
Thinking the tall kettle has high pressure on the bottom, raising the boiling point and as does cycle up to a boil, the pressure drops and boil becomes near violent.
Any one have insight as what is going on?
tnx
