how many psi MAX
    #3449229 - 12/05/04 11:04 AM (12 years, 8 months ago)

ey there!

lets say someone got a pc that can do some more than 15 psi and it requires
that person to operate the pc at 18psi in order to archieve required sterilisation
temperature.

i wonder, at how many psi MAX one can operate the pc before the pressure
would actually damage/compress the grains?

short, but precise question :wink:

To my understanding, Jars are sealed air tight. Last I checked solids were not compressible. It is not the pressure that sterilized but the higher temperature as a result of the increased pressure.

You're not going to damage/compress your grain. Compression can only occur when there is an unequal force. Since everything inside your PC is at the same psi, can't happen. (Don't seal jars airtight)
You will however be creating an unsafe condition if you exceed the manufacturers recommendation. Best to stick with 15psi. Why risk being badly burnt or killed by a stovetop bomb?

heh i see ur point,
but still as i said, the required temp is archived with that unit at a setting
above 15psi...

so if i were to cook them at 20psi,
this wouldnt do any harm?

There is alot of ugly misunderstandigs goin on around here as of late about the "proper "safe" use of jars in PC's lately . That or some serious miswording  :frown:
It is becoming a pet peve ... kinda like spelling for you  :wink:
Perhaps we need a button like the spell checker , except it would be a proper tek button that corrects falsified , misleading statements from being broadcasted  :tongue: :wink:


Follow manufacturers directions folks .
Most of things we all do here only require 15 psi(250*F) , so stick with the plan and you'll do just fine , and remeber if no holes in lids ,or invereted , keep the band and lid lose , tighten them up when they start to cool down enough that you can hold jar with a clean hand towel , well thats what I do  :tongue: and I'm just a fool with a PC , all my fingers and toes , no claims on insurance for burning down house , and no burn scars . :thumbup:(knocks on wood )

What are you reading that requires higher psi setting ?

Okay .....

15 psi "MAX" for 1.5 hrs
If concerned not sterile at that point let it cool refill PC and cook again for another 1.5 hrs ... short sweet and to the point !
GL

Would it harm grain .... NO
You or the PC ...... who truly knows !!!!! :smirk:

15psi is 15psi, regardless of your pc. If you did yours at 20psi, no problem. If the manufacturer says that their pc is safe to use at 20psi, no problem in this case. Your pc is reaching the same temperature at 15psi that everyone else's is.

actually it didnt reach 250?F=121?C unless i was tweaking pressure to 17psi.
anyways, mine is safe to be operated up to 30psi.
btw, its been cleared since the grains were just looking normal,
thx for everyone who participated in the thread.

Living in Death Valley are we ???

Right ... lower alt means higher pressure to achieve temp ???????
Higher alt things boil quicker ......??????????

Nothing , just ramblin on .............

But 15 psi is 15 psi with same temp , with exception of varying altitudes .

15 psi at "sea level" =250*F

No offence but... Please try to learn the hobby before giving advice.

Jars are not air tight... Solids are compressible, it's called density... pressure does help to permeate the grain for sterilizing...

Your comment "higher temperature as a result of the increased pressure" was correct. So 1 out of 4.

use it, it is only better. 20 psi would only garuntee that nothing would live. it wont hurt shit

Stop experimenting half way through your first grow. Grow it to maturity, watch it, learn from it. Do this a few times then experiment with different ideas and figure out what works best for you.

Correct.
He is at an altitude of ~1000ft above see level, thus the need for a higher pressure to achieve the same temperature.
