Canning at Aerial Altitude
Using the action time for canning aliment at sea akin may aftereffect in accident if you alive at altitudes of 1,000 anxiety or more. Baptize boils at lower temperatures as distance increases. Accretion the action time or canner burden compensates for lower baking temperatures. Therefore, baddest the able time and burden for the distance area you are canning.
Canning aliment altitude.
The afterward table can be acclimated for burden and temperature about-face for canners that use the metric system.
|Boiling baptize temperature and associated pressure|
|° F||° C||Pounds per aboveboard inch (psi)||Atmosphere (atm)||Bar|
A abounding barometer comes in three burden settings: 5, 10 and 15 lbs. Afterwards the canner is actuality vented, the burden central is 14.69 psi and the temperature at 212° F, 100° C.
- Adding a 5 lb abounding barometer increases burden to 14.69 5 = 19.69 lb of burden which corresponds to about 227° F, 108.5° C.
- Adding a 10 lb abounding barometer increases burden to 14.69 10 = 24.69 lb of burden which corresponds to about 240° F, 116° C.
- Adding a 15 lb abounding barometer increases burden to: 14.69 15 = 29.69 psi. This corresponds to 250° F, 121° C.
Recipes usually account processing times and pressures for altitudes of 0-1000 anxiety for punch blazon and abounding barometer burden canners. If you are canning at college altitudes, chase the USDA distance adjustments listed below.

NOTE accomplish abiding you apperceive the blazon of your burden canner.
If your compound calls for 15 lbs. burden at the sea akin access the burden 1 lb. for anniversary 2000 anxiety altitude. Appropriately at an distance of 4000 feet, action aliment at 17 lbs. of burden instead of 15 lbs. pressure. If you canner will not acquiesce you to access the burden over 15 lbs., access processing time 20% for anniversary 1,000 ft. acceleration in altitude.
