PC: how much steam?
    #7788517 - 12/22/07 10:40 AM (16 years, 1 month ago)

I'm using a cheap PC that reaches only 11 PSI with good results. Pc'ing 750 ml rye jars for two hours is enough for sterilization. with time, some questions arise. the amount and strength of steam released trough the valve, get correlation with the pressure and temp into the PC? Intuitively, I prefer overheat the PC in order to release more steam more vigorously, supposing this warrant more temperature and pressure. It's correct? I'm doubt

what?? First off you people with bad english need to state where they are from so we do not get extremely pissed off at the us educational system. If you are a us citizen, jesus fucking christ. Go back to school.
They will be fine at 11 psi for the size jar that you are using. You could probably go less if you are boiling the grains first then pcing them. Cooking them for 2 hours is going to increase the chances of caramelization. Go ahead and try. If they are bad I will give you $100 for your time.

Next, your pressure and temp are relative of each other. It requires a certain temp and certain rate of boiling water to create the psi that you are reaching.
I would like to explain this to you but it is way over your head.
although if your pc was air tight like an air compressor then you would be able to get it to 11psi without heat.

Tahoe, you are really grumpy today, be a bit more patient.

RE: PCs. Your PC will not release steam until it has reached the correct internal pressure and then, any steam released is excess steam. At a given pressure, you can only get a certain temperature because once the water starts boiling (at higher temps under pressure) temperature will stabilize.
So by having clouds of steam coming out of your valve, you are not increasing the temperature and wasting water from inside the PC risking it drying out.

yeah what nibin said.
I am grumpy this morning, too many somas last night.
The weight/rocker on the pc only really neds to be slightly moving. One jiggle a minute. If it is going nuts you might be .5-1 psi higher but you are wasting steam and the temp isnt going to play a big roll.

Please do us a favor and drop your pc time down to at least an hour. If you are cooking your grain beforehand to get the moisture then I gaurentee that you will be fine at 45 mins at 11psi. You have to realize that it is sterilizing while it heats up and cools down. So you will have alomst 90 mins of cook time as is

I disagree that you should lower your cook time. You can try it, but chances are very good that at 11PSI you will not sufficiently sterilize all of the endospores and you'll end up with bacterial contamination.

I always PC grains for at least 90 min, even at 15+PSI.

if boiling first I bet he is fine. I used to cook my 1/2gallon and 1 gallon jars for 1 hour. These jars we just seed +water and then cooked. They were not mixed and boiled first, no steeping. I was always sterile. My pf cakes would go in for no more then 20 mins at 15 psi. They were fine. Cook longer, great. Try a little less, save time, money. Just give it a shot with 2 jar. See what happens

If you can get away with it, by all means do so. :thumbup:

Personally, I had contamination issues with WBS at anything less than 90 min @ 15PSI.  Given, this is also at 6,000ft. elevation.

makes sense. I am supposed to visit my mom in nm and I would fly into el paso. I guess there are mountains over there. I thought only two things came from texas......................Okay bad joke

Most of my growing past has been in Colorado, not Texas. :biggrin:
