Looking on opinions on how to pasteurize large amounts of substrate

Let's say just in theory that SWIM, a FOAF, my dog.........ok ok I won't do that to yall lol.
Anywho if I wanted to pasteurize roughly 80 quarts of coir or compost in one or two separate runs, if it was you, what would you think the best way to go about it?
And dear god frank don't tell me to put it all in jars on the stove lol.
I have access to large metal trashcans, plastic 55 gallon drums, and an outdoor propane burner setup.

Another frankenbed in the making perhaps?
What about setting a 30 gallon barrel inside of a 55 gal barrel of water and using a fire for a heat source Just a thought

I don't see how you can guarantee even pasteurization with such a large volume of substrate.....I suspect breaking it down into relatively smaller batches would be a prudent decision.

A wagner steam unit connected to a large, double-stacked tub would be the best bet. Blake_shroom I believe has a write up about his.

Cant find the link for this bulk steam pastuerizer but heres mine. The wagner steamer just hooks up to the side with the hose. Works awesome but it does run out of water fast. I was thinking about converting the steamer to a 5 gallon buket.

You don't want to pasteurize manure or coir in a large amount of water the way we do with straw. It should be adjusted to field capacity and pasteurized in smaller batches.
Filter patch bags work well in a hot water bath. You could buy a 55 gallon drum from a local recycler, and then get a turkey fryer burner for it. That should let you pasteurize 50 or so pounds at a time. RR

I dont believe anyone was talking about water. And the bulk steam pastuerizer works on steam. The field capacity is still perfect after the run. What i do is get one or two of these giant tubs from walmart 
Mix my sub all up. Load into multiple oven bags. Throw them in the bsp... use a meat thermometer to measure the temp. Which hits perfectly 160 in about 30 minutes. Set the timer for 1 1/2 hours to insure pastuerization of the core of each bag. And bada bing, bada boom, your done. And i just completely pack the fucker sometimes. To the top. The thing works awesome!! Never had problems with early contams or over/under hydration or anything. And the tub is 50 gallons. Which means 200 quarts in one run!

I've thought about the Wagner or making my own custom design but the thing that worries me is the temp at which the steam comes over and trying to find a way to regulate it so the outside of the sub doesn't get overheated by the time core gets up to temp.

I've always heard that the core temp is all that matters because you only need toleave some themophillic bacteria. Not all

Really? I thought that's why the bucket tek was so frowned upon because in theory people sterilized the outside of their sub with boiling or close to boiling water.trying to get the core up to holding temps.

And frank I thought you built one of the Wagner setups and quickly abandoned it for your stovetop method? Also frank are you talking about modifying the original Wagner design to basically be a double boiler instead of having your sub in the tub directly where to steam actually comes out?

Actually I think the bucket tek gets the whole sub up to too high of a temp. When using only coir and verm I don't think this is a real problem though. In my humble opinion the bucket tek is often blamed for the inexperienced cultivators contamination problem when the real culprit was probably the spawn. I have spawned a lot of tubs the past few months using the bucket tek with no problems but this is a whole other subject and I don't want to derail your thread

Well in the past I have had success and failure with the bucket tek. Especially when I moved into my latest home. I have had better luck with breaking the coir bricks apart before attempting it, and only adding roughly 175degree water, the instead of opening to mix it I would take my insulated bucket and shake, flip, and roll it back and forth on the floor a few times. Basically agitating it.
But that's the only way the bucket tek has worked for me the few times I chose to use it in the last year. I think the main thing that helped was busting up the bricks with a hammer and screwdriver (those fuckers are hard to split any other way). But that coupled with using 170 or so water in a highly insulated bucket seems a bit better than boil and pour onto a brick.

My past 2 tubs I have pasteurized per fh's tek because I wanted to get good at it for when I get ready to use poo to grow some exotics. It wasn't as big of a hassle as I thought it might be but it still isn't as easy as the bucket

I agree his method is pretty optimal but not for anything nearing 80qts.

Dry heat is a very poor conductor so it would take much longer than using steam or a water bath.

Ive measured the core of an oven bag with a meat therm and it reads a perfect 160 along with the outside substrate and air temperature. This is a perfect setup. I swear by it.

Are you referring to the Wagner setup? If so I would imagine the size of your container comes into play. What tub size, how long does the tub take to get to temp, also how long until core temp is reached?

Its been awhile since ive used it. If i remember right about an hour for core. A 50 gallon tub. And i plan on making some in a couple weeks. If youd like id pay attention to all the small details and send u a pm.
