Survey: Pressure canner cool down
Frequent question on canning forums: Why does it take my pressure canner so long to cool down?
Times reported seem to range from 20 min. to 4 hours and while it should be size related, it doesn't seem to be.
So your pressure canner(s) - brand, size or model #, weighted gauge or just weight or just gauge, average cool down time, and any reasons you may have discovered that can delay cool down?
My Presto 23 qt. weighted gauge canner takes an average of 25 min. to cool down to 0 on the gauge (then I wait 10 mins. before removing the weight). My AA 915 weighted gauged one takes approx. 40 min. I think because even though it is smaller it is much heavier.
