Pressure Canners I Can Because I Can

Pressure Canners

pointsevenout 16 years ago

In my research of pressure canners I came upon some disturbing information.

Glass top or ceramic top stoves (smooth top stoves) have a temperature sensor built into them to keep the temperature below where the glass or ceramic tops will crack. The elevated temperature of the steam in the pressure canner radiates the elevated temperature back into the stove surface, especially when the canner bottom diameter is larger than the heater element diameter, which shuts down the heater element until the temperature lowers to a safe level to protect the stove top.

The end result being not a complete kill of bacteria in the food.

Does anyone have any practical experience in this matter or additional information? Is anyone using a pressure canner on a flat top stove? Is this just a concern that has been blown out of proportion?

I don't know what the crack point temperatures for glass or ceramic top stove surfaces are anyhow.

Sprung for a pressure canner today.
Found out from my range representative that I need a flat bottom canner so the heat will sink to the pot the best. And I should have no issue with the overtemp sensor shutting off the range. Because, as the rep pointed out, I can, and do, fry foods in oil at 350 degrees. So reflecting temperatures of 240 to 250 degrees, which is where the pressure cooker works, back into the range top is not a problem.

One step forward and two steps back.
The canner won't boil a gallon of water. :-(
I'm thinking there is too much overhang of the pot past the element and the reflected heat is shutting off the element.
The pots I cook with oil in them are sized to the element.
Would like to take the pressure cooker back but it is discolored from trying to boil water.
Maybe I can get someone to fashion me an aluminum disc the size of the element and an inch or so thick so I can get the pot up off the element and still maintain the heat sink.
