pc two valves question
    #15662648 - 01/13/12 08:52 PM (12 years, 5 months ago)

I just bought a small pc and it has two valves.
in manual it says that one is a cooking valve and the other is safety valve..cooking valve operates at 0,55 bar (8 psi) and safety valve is
1,1 bar (16 psi)..
So my question is, can i rely only on safety valve to pc at 16psi? or am i supposed to work with only cooking valve?
my guess is that safety valve should never go off right? if that is so,
should i be ok if i use only 8psi and double the time with sterilization?

thanks

The safety valve should be rubber or something like that. The cooking valve is the valve that slides open/closed maybe?

No.  Operate at 8 psi.  This way, the only time your safety valve opens is if something goes wrong.  Every pressure vessel needs two means of pressure relief for safety.

You don't need over 8 psi anyway, because you can simply increase the time.  I sterilize thousands of pounds per month for our commercial mushroom farm at 1 psi for 8 hours. At my elevation in the mountains, 1 psi is just below 212F/100C.  I have 100% success this way, which is essentially using the brf tek sterilization process, but for 7 pound supplemented substrate blocks for a longer time.
