Over 15psi?
    #9833824 - 02/20/09 02:11 PM (15 years, 10 months ago)

well i have to ask... ever since ive been using my protable burner it seems to jump around a tiny bit (psi's).  My question is, what happens when it does jump around?  mine goes from prob 15 to 15 1/2 usually but sometimes even reaches 15 3/4.  how does this effect the grains?  what about 16psi's? (note: breifly stays over 15psi, like i said it jumps a little here and there.)

What about when it goes under a bit? (trying to decide wheter its better to have it go over (up and down) or under (up and down)

Ive noticed w/ the rye, it seems to look a bit more "dehydrated" when it fluctuates.  Im doing wbs right now afetr doing rye for so long its a pian in the ass (especially after using RR's rye tek)

If you have a rocker-weight type PC, then error on the side of under 15psi. You can even keep it at 14psi to completely stop the rocking. If you have one of the valve type, then you can do whatever you like.

well i have the 16 qt presto, it has the a automatic air valve/cover lock, pressure guage, and the "rocker". THIS ONE HERE

what are the effects of 16psi (curious), does it over cook the grains, burn them, or "dehydrate" them somehow??

Well, you're cooking at a higher temp.
The difference is gonna be like 1/3 of a degree, maybe a little more or less. I wouldn't worry about that.

The problem with a rocker at that high is that you're gonna lose water really fast. -> possible changes in pressure and possible drying of the PC.

Going over pressure when you have a rocker type PC causes the rocker to go nuts, which also causes moisture in your grain jars to escape.  The pressure itself isn't the problem, it's the venting.  I replaced my weight/nozzle on the AA with a valve, and routinely PC at 20 psi.

I just tape some extra weight on top of the rocker to keep it from going nuts.  In fact, I'm currently pc'ing some wbs and taped a couple of screw bits to it.  I just make sure that I monitor the pressure until it stabilizes.  I found that I can turn the heat down a lot because of it.

I would still run it the same amount of time.
Hey RR what are the effects of hitting 18-26psi when using filter patch bags.  they are the sporeworks ones or whatever.  I think that they all sell Unicorn bags anyway, but in smaller quantity

I just used regular ole scotch tape.  Since the rocker isn't, well, rocking, the tape holds up just fine

Please be careful guys. PC's won't kill you, but they are dangerous and can detonate. I don't want to see any shroomerites in the hospital.

I'm actually irrationally paranoid about the pc blowing up.  That's why I watch it like a hawk until it stabilizes around 15 psi.  I'm too scared to make it go any higher.  Mine has a rubber plug as an emergency release and I always make sure that it's on the far side of the pc when I check the pressure.  I have a picture in my head of the scalding water bursting forth all over me, which is why I treat my pc like a loaded gun.

RR, what kind of modifications did you make to your pc?

I actually treat my PC better than a loaded gun... guess that's why I almost shot myself in the foot that one time. Thought I was out of bullets and pulled the trigger. Ended up with a hole about 1/4" away from my foot.

The PC (non-electric ones) gets my attention until it reaches 15psi, then I stay in the room until it completes.

I replaced the nozzle and weight assembly with a 1/8" NPT(national pipe thread) stopcock, available at any NAPA auto parts store. They're intended for use as radiator drain valves. I open it up to allow the PC to vent and then slowly close it after ten minutes or so of venting.  The valve itself only cost $1.50, so it's a lot cheaper than the rocker valve AA sells.  I like it better because I can leave it slightly cracked if I want to.

However, I don't recommend the above modification to anyone who tends to drink or smoke out while the PC is running.  You're defeating half your safety factor by doing so.  With that valve closed, the only thing to keep the PC from blowing is that black rubber plug, and if it blows out, you're screwed because it usually destroys it, and you're down until you order and receive another.

I don't use less time when I go 20 PSI because I live at altitude in the mountains, so the extra few PSI in actuality only give me roughly the same temp as I had when I lived in Seattle at sea level.  I PC quart/liter grain jars for 90 minutes, and 5 lb filter patch bags for 120 minutes.

RR do you have any pictures of this valve?  I'd love to see.

this is the AA #65 valve.  Just my MO but I stick to factory parts when it comes to my PC.  Not saying anything bad about the alternative valve but I paid 450$ for this bad boy and an additional 15$ is chump change to me if something should fail with the aftermarket one.



Yes agreed most definetly.  I fell asleep once and pc'd some jars for 4 hrs and the the jiggle woke me up.  On the other hand I like doing my bags and just turning the stove off and going to bed.  The stopcock valve will not suck in any contam air.  I have a 100% contam free success rate opening my PC the following day after venting it via alcohol towel.  sealing the bags in open air.  lots of oust, central heat and air shut off, medical mask, bouffant cap, gloves, tyvek sleeves, OH and alcohol 70%.

anyone got any views about higher pc pressures effects on the above noted bags from unicorn available from all vendors

i cook at 24 psi. i feel safer that way. i do pack mine full of bags though so 2hrs at 24 psi promises success.
