Sterilization Pressure/Temperature & Duration Table

Couldn't find one when I first started. 
Instructions: Find your optimum operating pressure/temperature follow the row until the intersecting line and read the suggested time at the bottom of that column. Example 15psi = 90min

I hope this helps, feel free to copy

So 10 partially filled quart jars will take 20 minutes @ 20 psi? Seems awfully short

I thought the same thing until I tested it with sterilization strips. Takes time to get to 20psi. Higher pressures requires increased heat applied. Plus it doesn't cool immediately, after 30 minutes after discontinuing heat it was still at 10psi

I highly advise against this sort of thing. You are flirting with disaster in a way that I doubt that you truly understand. A sudden discharge of that sort of force does all sorts of things....Flying metal lids...concussive blasts that can rupture eardrums etc (death included). Totally irresponsible imho. If you need higher than 15 psi, please get a proper pressure vessel for this.

While your modded PC also scares the piss outta me, I find this quite interesting as well, since I use an AA 75x and sterilize at 20 psi often.

also WillSolvem you got any ideas on bumping up my psi I've got a Philippe Richard 8-Quart Pressure Cooker, Aluminum its at 15psi but obviously i want to go higher better to killem all lol maybe 18-19 psi?

Cheap PCs that are "rated" at 15 psi WILL FAIL eventually if operated outside of the intended use. You need to really understand that at times it will present a life/death catastrophe. You obviously do not understand/respect pressurized steam, and TBH if you want to know how to void a warranty and possibly kill yourself, do it in pm. There are plenty of impressionable people who may think this is a sane plan, but I hate to be a debbie-downer, but just because Will has not blown himself up yet does not make this anything like a reasonable plan.
Do it in pm, because discussions of this nature CERTAINLY HAVE NO PLACE HERE. This type of tek has no place here. Mark my words, if enough people here on this site modify their PC to operate outside of specs SOMEONE will eventually die or worse....and they will have no recourse because they modified a pressure vessel without any understanding of what the consequences are.....Not to mention what any impending investigation may find....You may quickly find out that you would be getting medical treatment from the state penitentiary. Police tend to close in on noises that sound explosive pretty quick.
I work with HPS (High pressure steam) every day at coal, gas and nuke power plants. If you do not respect it, it will kill and others you quickly. 15 psi is childs play, but still certainly has potential to kill. Its like comparing a 30-06 to a .22.
Sounds to me you should simply stick with a crock pot and pf tek. I think the responsibility of owning a PC is too much for you.
TL:DR
15 psi is great for "killem all". I cannot fathom why anyone would risk disaster by modding a cheap chinese pc for 5 extra PSI. Quit being cheap and dangerous to yourself and others, and fork over the funds to get a cooker that will do 20psi safe. Otherwise you are a total fool.

There's no real reason to go over 15 PSI, especially in vessels made for 15psi, except to try as an attempt to make up for flaws elsewhere in cultivation attempts.

Thanks but I don't mind the bashing, people have the right to their opinion and although I might not agree with it I'll defend to death their right to express it, so.. 
Without a gauge to read pressure even I might be reluctant to modify. Aluminum is soft though so drilling a hole and bolting a pressure gauge would be really easy, you could then add weight to the rocker weight. The rockers are steel and magnets stick pretty well or you could glue large metal washers until desired pressure is reached.
As stated above though, higher than 15psi isn't necessary, I opt for it when cycling wood based spawn or plugs or I'm shooting for more than four cycles in a single day for each autoclave (i actually have two of these both modded) and rely on shorter cycle times

Aluminum also will fail with time unlike steel which can undergo unlimited stresses below a tensile threshold.
You can stress steel infinitely many times as long as it's within a range of acceptable stress, The ranges of acceptable stress for aluminum exists to get long life, but you cant do the stresses infinitely many times you'll see failure eventually.
There's a debate on bicycles that makes it easier to visualize. like here.
Aluminum acts very differently, it's behavior in terms of ultimate tensile strength compared to steel are severe when talking about using it as a mission critical part that shouldn't be failing with 20 psi of nearly 300F steam.

Same failure that will happen when something goes wrong with the modded pc. Look at that kitchen....looks like a pork-bomb went off. Now imagine being in the kitchen when the cooker was apparently bouncing off the walls. I want nothing to do with any 250f heavy metal object expelling steam and flying around my kitchen.
Another member with Phillipe Richards 8qt pc
User indicated that afformentioned 8qt pc operates at 11 psi. Modding it to 15 psi would be a disaster, let alone 20. It may work a few times or more, but after looking up that model...Its a POS and should be ran at the intended pressure.
Great chart, Sorry to have taken it OT. Some things are serious enough to me that I believe they need to be pointed out and stressed upon. I really feel that most people do not have the common sense and respect for steam.

Yea I've seen the video before. Fully loaded my autoclave weighs ~ 28lbs not 4lbs. And the blowout plug did it's job. Like I said rubber not aluminum will fail first.
Either way please feel free to post your thoughts on my Tek under the Tek thread where your opinion would have the greatest impact on those considering the modification, let's stick to the topic here please  
Here's the link, see y'all there: http://www.shroomery.org/forums/showflat.php/Number/17000445

Ha that pressure cooker mod is awesome! Really dangerous for someone not mechanically inclined but cool never the less.
Your chart is for cooking at sea level yeah? Might need to increase some of the times if you live high altitude.

The sterilization times are the same in high altitude, it just takes more heat/time to get to your desired pressure than at sea level

I swear the United states government does more to protect free speech than some moderators on this site:
My autoclave Tek has been removed by prisoner#1 his stated reason was "it is dangerous"
Lol even RR claimed I made a bomb but still left the thread up so people can make their own decisions
The following is the rating I left him after he refused to expand on his reasoning for his actions
"I would give him ZERO SHROOMS but I'm not a dick. He took down a thread I posted that was over a year old because he didn't agree with it, says it's dangerous. He did keep up several threads on BHO, LSD, and METHAMPHETAMINE production that HAVE HURT THOUSANDS Your a moderator, moderate not dictate. I've said it before and I'll say it again, I may not agree with your opinion, but I'll defend to death your right to express it.
EDIT: Nevermind I am rating you zero, this has nothing to do with my karma. Aside from this situation he's generally a good Shroomer and ok mod"

I don't mind people flaming/bashing for my ideas but straight out censorship leaves a bad taste in my mouth that makes me want to forget this site and keep my ideas to myself instead of letting this community make their own decisions.
I'm done ranting back to topic (if this thread doesn't get deleted or I'm not banned)
I will rewrite the Tek on a different site and link it to my sig soon

I am not going to lie. I personally requested via the report button the removal of the thread. Because it is dangerous. Because of all the Tek's on this website, this one introduces the potential for catastrophic damage to health AND property.
It has nothing to do with free speech, after all this is a private forum. The mods reserve the right.
Its plain and simple. That tek simply was dangerous to EVERYONE who did it. It has nothing to do with ignorance or understanding of the dynamics of High pressure steam. It does not matter how much you think you understand HPS, because anyone with any scruples who remotely appreciates steam would not do it and advise against it.
The other issue I presented in my report was that WHEN someone blows themselves up, and the police get involved and it gets traced back to this forum/your thread.....Most likely nothing would happen legally, but I am certain that there would be police activity. They will want to know where some dude growing (most likely illegal) mushrooms got the hair-brained idea to make a pc into a bomb.
Do you even realize that IF a PC explodes and the police show up, there may be a pile of charges levied against the owner of the pressure-bomb. After the boston marathon incident, they will be more than happy to treat you like a terrorist until you divulge the real nature of your mod. "Oh I didn't want to destroy anyone, just wanted to save a half hour of cooking grain for my magic mushrooms"
A tek like that is only inviting disaster to anyone who does it, and to this forum and its users.
I did ask in the other thread:
Willsolvern: How would you feel if someone posted that they were burned horribly/hurt badly when they did your "mod". I have had 3rd degree burns on a decent percentage of my body one time. Google "Debridement" and ask yourself if you would like dead skin wiped off your body with a stainless steel wire brush. They did my whole arm in one day without pain pills. It is not a joke.
The lack of respect and understanding of steam just simply astounds me. You and your teks are not to be trusted based on your obvious lack of comprehension of basic physics.

That's your opinion, you have the right to it. Although we don't agree that was ridiculous. Please keep your space from my threads in the future.
Your reaching, very far to validate yourself, this tells me your feeling a little guilty for your actions. I forgive you but I'm still upset.
@RR I did not know it was reported until now, I'll remove my negative rating, but he could have done more to explain the situation (just like you did in one simple sentence) instead of ignoring me
@RR the blowout plug will depressurize the vessel safely if left to fail

@Gr13nMushDude
I appreciate you standing up for me.
Let's not worry and get back to the subject on hand. I'm really not that mad, just wish I could have copied the information before it was deleted.
I publicly apologize to prisoner#1 for jumping to conclusion. I didn't know the thread had been reported by a fellow Shroomer.
That being said let's get back to sharing knowledge

All of your mentioned items summarize what camp you hail from. All of the things you point out come with a number of redundant safety mechanisms from the factory (just like a pressure cooker)
I would tell someone the same exact thing (basically) if they were to disable things like the blow off valve on the water heater, or breaking off ground plugs and using incorrect breakers etc. My radiators run @ 1psi steam in the winter. Again, there are a number of redundant checks and balances that keep us safe (blow off valves etc). If you have an gas appliance, it has a pilot light.....if it goes out, the gas will shut off.
These are called integrated safety features. Disabling ANY safety item is stupid.
That steam boiler of RRs runs @ one psi. If you noticed how much REAL work was put into it. Show me one place where he does not have enough safety mechanisms. I did not see one thought of his that involved RTV silicone and ball valves to instead of blow off valves to up the pressure. Comparing a 1psi steam boiler to the increase of volume in a pc to an autoclave ARE 2 totally different things.
Gr13:
You obviously have no mechanical knowledge. I won't judge you for that. You seem to be more interested in complaining about things you don't understand than using common sense. I requested the removal of the thread so that people of your mechanical disposition would not be given any fodder to "try something new".
IT IS DANGEROUS TO DISABLE ANY INTEGRATED SAFETY MECHANISM. IT CERTAINLY IS AGAINST THE MANUFACTURERS WARNING, AND WILL EVENTUALLY FAIL CATASTROPHICALLY.
This applies to ALL THINGS that have a safety mechanism.

For the record, that depends on the BTU rating of your stove. The blowout plug has a fairly small opening and can only release so much steam. In addition, they're made from rubber which tends to get stiff and brittle over time. Yours should have blown before the gauge read 30 lbs.
There should always be at least two means of overpressure control in the event that one of them fails. My 55 gallon drum boiler has three means of overpressure control for added safety. RR

>IT IS DANGEROUS TO DISABLE ANY INTEGRATED SAFETY MECHANISM.
No safety device was disabled, I would reference the Tek to prove this, but your actions removed that possibility.
I will not ask again, let's get back on topic

Bud, you made it clear that you don't have a clue about how steam works. Ill tell it to you like this. I work with HPS every day in power plants. I am dealing with a few hundred pounds of pressure OR MORE going through double xtra heavy wall 9 chrome alloy. I have over a decade of experience. I am highly overqualified to do the work I do. I have certifications for things that I guarantee you cannot imagine.

Once the seal on the vessel has been broke (popping the blowout plug) it will no longer create positive pressure. I agree triple redundancy is preferred, this system does rely on a very observant operator.
If you will see in the Tek I replaced the blowout and other fittings recently and are replaced every few months even if in good condition.

A ball valve used in place of the rocker is one example. The rocker is one of up to 3 redundant safety mechanisms that are built into every pc. This is one example of a disabled safety mechanism.

Thank you for your input, would have been better served under the Tek thread. Now it's being rewritten as a journal and you now loose the ability to voice your concerns in a proper fashion. Good job 
The Tek will live on without you

Its not a tek, its a disaster waiting to happen. I hope you don't hurt yourself. Im blocking you now only because I have effectively wasted time and intelligence in what seems to be a one sided issue. You are wrong, plain and simple. Do what you do for yourself by yourself. Don't give more people with your lack of understanding bad ideas that are potentially deadly.

Find me another way to hold a vacuum upon cooking and I'll take it into consideration.
The rocker was not replaced with a ball valve, I would point you to the Tek, but you know how self appointed policing goes

No rocker at all? You are lucky there that you really did not blow yourself up.

As a side note, I remember when the "Short Magnum" high power rifle cartridges came out. Some manufacturers would not make barrels for them because the pressure curve was to dangerous for the materials that the barrels were made out of. The manufacturers had to rethink the makeup of the barrels to accommodate the high pressures that were dangerous to conventional chambers.
You can't reinvent the wheel. I run my sterilizer at 17 to 20 PSI when doing grains, but I don't let it become higher than 15 PSI for agar.
I liked the analogy of shooting a .22 cal long rifle cartridges and then trying to make it into a 22-250. That analogy is alarming.
For those of you who aren't familiar with rifle cartridges, the 22-250 is on the left and the 22 long rifle is on the right.

There is a deadly difference.

That is a great way to describe it.
I blocked Will, not because I am shamed by him, but because of his inherent lack of knowledge. I guarantee that I will learn nothing from him and his antics. I really don't want to know what he does with his pressure cooker. An autoclave and a pressure cooker are 2 different monsters with similar properties. I have not been subtle at all about what I pointed out. Just because he cannot comprehend that he did disable integrated safety mechanisms, does not mean at all that it is safe. What was done was totally unsafe. There is no other way about it. It is all wrong. All I requested is that you keep that sort of bs to yourself. There are too many impressionable minds that simply don't comprehend what they are dealing with...Will included.
I will continue to "police" threads and report ANYTHING that looks like a bomb. 30+ PSI in a cooker rated @ 15 psi is a bomb.

Aluminum is soft though so drilling a hole and bolting a pressure gauge would be really easy, you could then add weight to the rocker weight. The rockers are steel and magnets stick pretty well or you could glue large metal washers until desired pressure is reached.

I thought it was a dead horse the first time you made a thread about this terrible idea, but it turned out to still have some life in it. Yes, I'm beating a dead horse, but since this horse is a dangerous asshole I think I'm just going to keep beating it for a while.
