The psi rating on them is really high. I agree this is deadly dangerous. But what about if you ran it at 5psi would it sterilze grains then in 8hrs? Or 10psi?

But I suppose once you spent $700 a barrel for 5 brand new stainless steel barrels you'd be better off to just buy this 150L autoclave and call it a day

I don't think enough info is out on endospores/thermofiles and 10psi, I've seen some stuff, but idk, I wouldn't bank on it, Not would I bank on it being much safer.
I mean I feel the idea. Everyone wants more PC space for cheap. Probably since the beginning of the PC/mushroom cultivator merger lol.
Plenty have wondered. Plenty smarter than you and I. Hopefully not too many were hurt.

15 psi is mighty dangerous in a barrel. Most of the time steel barrels will begin to distort around 2-4 psi, stainless will do it a little bit later, but not much. Once you start distorting the lid you also start to change the shape of the mating surface of the lid, which makes catastrophic failure much more likely. When the lid eventually blows off it will instantly convert 55 gallons of steam into boiling water, which will quickly cover and burn everything in the area, in addition to turning the lid into a missile.
This is the sort of thing that gets people killed.

Just saw that this guy is or was selling 4 of the 5 he build as 1-15 psi sterilizers on a Canadian marketplace.
Don't sell this shit to others man and make them believe it is totally safe to max out on the pressure. Put your own life in danger...sure go ahead, but not the life of others for a few hundred bucks.

Normal barrels are certainly not pressure rated at all because they are not pressure vessels.
I don't know if you found some crazy special barrels for nuke waste or something but no one should try to replicate this lest you die extremely painfully.

No shit I was talking to someone the other day who currently grows a couple thousand pounds of mostly oysters and shiitakes. He said that when he first started he modified a propane tank with a guage and just fed steam into lol. He said he tested it to 80psi even but this was like 10 years ago he said. His family had been farming for generations prior as well. But idk, I could help but clinch my buttcheecks at the thought. I hope he was stretching the truth a bit, but I sadly don't think so lol.

An old propane tank could make a great sterilizer with some fab work. They are designed for over 150 psi with the safety rating way over that.
Definitely a better choice than a 55 gallon barrel which was never intended to be a pressure vessel!
TO BE SURE NO ONE SHOULD BUILD THEIR OWN STERILIZER! Thats just crazy now. Get some help.
