Venting A Pressure Canner
Venting A Pressure Canner. Also called a vent port or steam vent. If there is air in the pressure canner, the temperature is much lower than if the canner contains only water and steam.
To do this safely and effectively, a pressure canner must have a ul approval symbol and meet nchfp guidelines. You can see a quote for it here: A vent port that opened for venting and closed to build pressure, or a vent port that was covered with a counter weight after venting.
We Want To Know The Temperature Of A Properly Vented And Exhaustwed Canner.
This step removes air from inside the canner so the temperature is the same throughout the canner Turn the heat all the way up to high and bring the canner to a boil with the steam vent open. One of the neat parts of pressure canning is that you don’t have to.

A safety fuse (or plug) was also present. Now with 2 to 3 inches of simmering water place all your jars to be pressure canned carefully and lock the lid of the pressure canner with no weight on the pressure vent. A set of 3 weights (5lb, 10lb, 15lb) that can be used individually or stacked to regulate pressure for a weighted canner that covers the vent pipe.
Simple Solution Is That The Lid Never Goes On The Canner With The Weight In Place.
Most modern pressure canners should also have the following key features: A vent port, either in the form of a petcock that opened for venting and closed to build pressure, or a vent port that was covered with a counterweight after venting. After venting canner for 10 minutes, the pressure regulator is placed on top of the vent pipe and the pressure will start increasing.
A Safety Fuse (Or Plug) Was Also Present.
E2i canner cover after venting. You can see a quote for it here: Removable ventilated racks, a locking lid, an automatic vent/cover lock, a steam vent, a pressure gauge or regulator, and a safety plug.
Venting Is Also Called “Exhausting” The Canner.
Pressure builds up, air vent up, the canner is being vented, 0 psi. Leave weight off the vent port or open the petcock. At this point you’ve sealed the lid, but the canner is not “sealed” in the true sense and it’s not yet coming up to pressure.
