Water Jacketed Canner Question

[Jim Schumacher]

Kirkhedding, this is a proto-type I made about a month ago. There are improvements coming. It is built out of 22ga annealed 316 stainless. There is some distortion in a few places, nothing bad, but I want it perfect if I ever try selling them. I never even polished the welds on this one. I had special heat-sinks and jigs machined to build them more efficiently with less distortion for the next ones. The jacket is sealed to the liner except in two of the corners where I have small holes to vent if anyone ever tried to plug the water jacket fill port. The thermometer is tapped into the water jacket, I wanted it about mid height since there is a 13 degree difference in temp between the top and bottom of the jacket while it is heating. On this unit I bought the element and thermostat from Tempco Electric. The thermostat didn't work. Currently a different company is building me a fixed 185 degree thermostat just for this purpose. The electronics are inside of a cover in the back of the unit.(see Pic) I also have some high-temp rubber feet coming that will be attached to studs in all four corners.

Here is a question... How did you seal a passage from the inner tank thru the water then thru the outer jacket without mixing the water with the syrup. seems to hard to do without robot welders. It does look beautiful, but any mixing would thin the syrup.

Zilla, I realize the importance of sealing the water jacket separate from the syrup compartment. Thanks for checking it out.
