Just Google the name and model and there is a PDF file for it. Yeah the do use dry heat for metal instruments and such. Sorry can't copy a link.

No worries, i'm not the type to go buy second hand hardware without knowing the specs. Btw i don't like to buy second hand stuff, but in that case when i saw the price of brand new big autoclave, well ...

So, after some time working the numbers (theoretically of course) my main concern is the time spent waiting that stuff are steriziling, preparation of all the shit, etc
was still searching a big autoclave as i want to be able to sterilize spawn and substrate without doing a run everyday, and found that (which is in the affordable price range for me) :
https://www.alibaba.com/product-detail/280L-150L-200L-400L-Pressure-Steam_60141528957.html?spm=a2700.7724838.0.0.7gCa5I
what do you think about that, i know it's Chinese stuff, but well, it's somewhat just a metal drum with big heater elements, and is so much cheaper that the brand new ones i found here, that's ridiculous.
Also considering the probably high price of shipping something that big (i expect 1k-2k here), i'll probably take the 400L one.

I've read that you have to be careful of Automated autoclaves at the end of a run some of them dump all the pressure at once. For instruments and such it s not a problem, but for bags they will expand and explode. Something to check out .

I built a shed thats 3x4m for less than I paid for 2x400L stainless barrels that held pressure. Holds more and it's less work rolling stuff in on racks. Just before you buy some Chinese thing, might want to look into atmospheric steam.

Well i gave it some thoughts, i admit i'm guilty of some laziness here, but i have some money left, and that could prove a handy piece of equipment.
Btw, i have plenty of space already(pretty soon to be exact), so that's a non issue (the new house got 800+m² of buildings/sheds/hangars, not counting the living space itself)
I'm trying to ease the process of growing in a semi lazy way, knowing that i have a bit of money to throw at it.
But thanks for the advice, you made sense btw.
i guess i could have a better use for that money, that's granted, but i don't feel like building stuff from scratch now.
I think you will also agree that's it useful to sterilize stuff fast.

Amen, get a few (like 3) cheap Chinese sauna steamers and a 1/4 size shipping container; or better yet an old insulated cube van box and you'll be laughing. Low pressure sterilization is cheap and safe, if you live in north america.

How much time is needed to sterilize with such a system ? 24 hours? also, how much water consumed for a run and power?

I run 4x6kw steamers for 24hrs. That's about $50 in electric to cook 400 bags. I could do 800 at a time but I'd need to buy new rolling shelves. Water, I don't know since I have a well its free.

576 kw/h of power would be more like 90€ here, but still interesting considering the number of bag you can sterilize.
i'll think about it.

Yea i use atmospheric steam too, its easy and reliable. I use a 1500w element to heat 220 lbs of sub for 24 hrs, costs me around $5 in electricity. I'm building a 85 gal one that will hopefully do around 300lbs of sub but using a 2kw element for the same 24 hrs.

I agree, atmospheric sterilization is the way to go for small/medium scale growers. I use an insulated 140 gallon stock tank that holds 84x 5 lb. bags. Uses a 6kw sauna steamer.

Do any of you also use that same method to sterilize spawn? seems to me it could ne a bit unreliable for grain ?

I haven't myself yet but i hear of many trusted growers here do. I plan to throw grain in once i upgrade to my larger steamer. The basic sterilization math from what I've gathered is lethality is X temp + X time = 100% lethality regardless of substrate nutrition. (clearly not an actual formula lol) The lower the temp the longer the time and vice versa.

i found a 33 cubic meter container(6 meters long) for about 1.5k + 600 shipping i guess i can expect to get the steamers pretty cheap.
it's appealing to be able to heat treat as much substrate/grain as you want in one go.

You can only do your final grain transfer at 100c, whether it's g2 or g5.

What's the logic behind it ? no matter what, some endospores will survive 100c an indefinite time?
