I am interested in your 35-gallon stainless steel container for pasteurizing milk. Is the jacket all the way round it? Can I run 165-degree water around the inside tank to heat up milk to 160 degrees and how much pressure, can the jacket handle?
Yes, the jacket goes all the way around, bottom and sides.
I am not sure how much pressure you would want to apply but I imagine you could run a pretty good stream around it.
There is an inlet and outlet so I assume that it would be easy to run water in to it.
The tank is designed to go beyond boiling point. 160 to 180 degree temperatures are commonly used for making liquid soap, so I see no problem with milk.
