Buying a Pressure Canner
Major decisions include size, type of gauge, and
price ($85-$300). Sizes range from 10 quarts (holds 4 qt. jars) to 41
quarts (holds 19 qt. jars).
Small canners are less costly and best suited for those who preserve
only small quantities of food. Large canners using two racks have
disadvantages as they are extremely heavy when fully loaded; may be too
tall to fit between the range unit and hood or overhead cupboard; and
require a longer exhaust and cooling time. Small pressure saucepans such
as ones used for cooking a meal are not recommended for home canning.
You will need to decide between a pressure dial or a metal weighted
gauge. Dial gauges actually show the pressure inside the canner. You
must read the dial and adjust the heat to control the pressure. Pressure
adjustments for altitude are easy to make. Dial gauges should be checked
annually for accuracy by mailing to National Presto or visiting
Extension offices with testers. Failure to test risks the possibility of
unsafely processed food.
Send to: National Presto Ind., 3925 N Hastings Way, Eau Claire, WI
54703. Ph: 800-877-0441. National Presto only charges for shipping,
but does not charge for checking a gauge. Wrap the gauge securely in
foam or bubble wrap and use a corrugated package suitable for shipping.
A weighted gauge will rock gently or jiggle periodically to show that
the correct pressure is being maintained. You can hear the jiggle and
know when the canner has reached the desired pressure. Weighted gauge
pressures are limited to 5, 10, and 15 pounds. No testing is needed.
