Quickest way to cool down Pressure Cooker?
    #1780701 - 08/05/03 07:33 AM (18 years, 4 months ago)

What is the quickest way to "de-pressurize" and cool down a pressure cooker so that a new batch of jars can immediately be loaded up?

How long should it cool?

My buddy already has 2.

damn the labels are deceptive.. 12 quart pressure cookers only really hold 8 wide-mouthed quarts.

You should avoid rapid cooling pressure cookers for a bunch of reasons that you won't listen to, so I'll give you a suggestion.  :smile: 

Just turn off the heat and gently mist the top of the cooker with water.  That will cool it down fairly quickly.

I dunno about differences between models and stuff, but my pressure cooker has a weight at the top that can simply be removed to de-pressurise in about seven, mayby seven and a half seconds... what's your's like?

take the entire cooker to the sink and run cold water over it.

Moving a hot, heavy, pressurized, steam-belching cooker around isn't a good idea. Spray it with a water bottle. That'll drop the pressure quickly and safely.

> take the entire cooker to the sink and run cold water over it.

This is a great way to earn a trip to the store to buy a new pressure cooker. (In other words, don't do this or you will ruin your cooker!)

Just remove the cooker from the stove and go smoke a J while you wait. Quickly cooling a cooker is a good way to ruin it, and crack your jars as well.

Just be patient and let the pressure drop naturally.

I usually wait 30 min from when I remove the heat to when I open the lid. Otherwise, I get this:

take the PC off the burner and turn a fan on it. You can also use a fan on the jars when they are finished, to cool them more quickly.

Rapid de-pressurization can also boil the water out of your substrate jars.

Water boils at a higher temperature when under pressure. If you rapidly decrease the pressure, the boiling point point temperature also drops and the hot jars will boil. This can dry them out or if they are sealed, make them expolde.

It works the same way a hot soda does when you shake it up and open it. By releasing the pressure you allow the gasses to escape the liquid very rapidly.

Except with water in a PC you are allowing the water to expand once the pressure is off of it and the super heated water evaporates at an extreme rate.

I agree with Seuss and others with one addition. . .quickly cooling down a PC can increase the incidence of contaminants. The water vapor in a hot PC condenses as the pressure drops, which sucks in outside air. This outside air has to go INSIDE of your cooling jars to make up for the negative pressure created as the water vapor condenses. Cooling slowly allows a slower infusion of this outside air, and makes better use of the filter disk/polyfill/watever filter you might have in place.
The other reasons should be reason enough, but this is one other small point.
