Cp pressure cooker questions
    #28478518 - 09/22/23 09:45 AM (1 year, 3 months ago)

Hello,
I have some pressure cooker questions that I haven't been able to find answers for...
I haven't been able to get my pressure cooker to get up to 15 psi no matter what I do.  Cpl things I am wondering about??  I can only get it up to 12 psi but can't hold it there.  10PSI is what I can constant pressure at.
1-I read somewhere that you need to add 75% more time for 10 PSI.  Is this correct? Is 15psi for 90 mins equal to 10 psi for about 2hr40min?
I have read that some grain won't work at 10 psi. I s that for whole oat grain?  What about cracked to whole corn?
2-Can you over pressure cook whole oats?  I accidentally left my pressure cooker go for an extra hour(3.5hrs @ 10psi).  Does that destroy the oats?
3-Making LC at 10PSi.  What time PC for?
Thanks

What model pressure cooker are you using? What size weight does it have on the steam vent?

I live at 5,000 altitude . My Presto says only 12 psi but the wobbler does wobble so I add 22% more time when I PC anything

its a 50qt pressure cooker I got off Wayfair.  Needed it big but had to get it on budget for now.  Weights only for 40KPA.  I haven't been able to find 100kpa weights that fit as they are a lot bigger stem than usual.  The bore hole for the stem is large and the 80 kph weights from amazon are small and don't fit on the stem.  I have rigged some chunks of metal up and have them sitting on the wobbler and can get it to about 12 psi but the other issue I have is the emergency vents seem to pop around 12.5 Psi.  I am saving for a better PC but for now I am stuck with this one.
I have these safety release valves but can't find ones rated to release higher than 15 psi.  these go around 12.5psi and sometimes less.

instead of having to have URL?)
WorkBigDan..Is 12 PSI only 22% more time?  I heard 10 PSI is 75% more time???  Can I over cook the grain If I go 75% more time at 10-12 psi?

Thanks

I pulled out one of the weights and added a pressure gauge to this PC so I can see what I am sitting at
