The Stanley Steamer Pasteurizer (with PICS)

Disclaimer: This is NOT my idea, but slightly modified on my part. Whoever's idea this was...feel free to take the credit: (and please post your original thread) ______________________________________________________________________
Got the steamer and promptly found a fitting that would fit the hose. (Cut off the screw adapter, slid the hose in, and used WaterWeld to bond them.)

Put the fitting into the side of the 33 gal Sterilite: (you can see the small holes drilled into the HPVC, and the wire rack)

Used WaterWeld to attach the PVC to the inside of the brass fitting:

Hooks in nicely:

The temperature probe (which has a digital read-out an attached alarm once it reaches X temperature...MEAT probe):

Up and running:

In some casing material used for the test run:

It hits (and holds) 167oF easily, should run a little cooler in the winter, AND will also be used to supplement the heating in my house.
Comments appreciated.

So I have a dumb question, is the steamer used constantly during the process or do you turn it off and on as needed?
It's nice and fairly self-contained. Looks alot less messy than the boiling water method.

I did something similar, however because I used a larger container (55-gallon "deck-box") I needed two hook up two Wagner Wallpaper Steamers to keep maintain 140-160(F) temps inside my bags of substrate and casing mixtures.
The reason I needed it so large is because I also pasteurize the hardwood that goes into my iguana's cage (huge) for both his litter and for his climbing branches. The wood can harbor various types of parasites and pasteurizing them first keeps him healthy.
Beyond that I wouldn't recommend making one that large for several obvious reasons, the least of which being that it's annoying that I have to plug the steamers into two separate electrical circuits - 1000W = 10AMPs - when I use it. Of course, being able to pasteurize up to 30 gallons / 4.0 cubic feet of mixture at once can be handy. 
I'm assuming whatever you called HPVC is the same as CPVC (Chlorinated Poly Vinyl Chloride) used for hotwater applications...good call, regular schedule 80 pvc will melt after the first or second use at these temps.
--- As for the original idea, I saw it a while on another myco forum and then again recently here so I can't claim credit either.

For me, I need to run the entire steamer until both of run out of water and then let it sit there for an hour without disturbing it for the internal temperatures of the substrate to get up to 140-160(F) and stay there - once again, deep within the center of the substrate - for at least an hour.

The test run actually ran a little over on the temperature, but I had the setup on an hour timer so I could pass-out. (Test run was just casing material anyway.)
Today the poo goes in, and the alarm on the temperature probe is set to 162oF (after which time the power to the steamer will be shut-off until the temperature drops 20-30oF, and I will turn the steamer on again.
I will be adjusting a 5 minute increment timer to hold this temperature for about 1/2 hour to one hour.
I had thought about wrapping the sterilite with 1/4" foam, and using colored duct tape to hold it all on. However, the temperature gets hot enough AND stays steady.
All I can figure is that the different materials insulate differently (although their thickness is about the same).
P.S.- The dried h-poo I got from a fellow Shroomerite (and hydrated myself) is of MUCH better quality than I got from TN Stud. If it produces nicely I hope they've got more where that came from.  I'll be sure to post pics when it is time.

Which steamer did you have hooked up first? If it wasn't the Stanley...that is why you needed to get another.

Glad I stumbled a across this thread. I'm actually building one of these tomorrow.

This is interesting. What is the logic behind it? It just uses the steam which pasteurizes the substrate through the bag? I've normally just boiled water. Well, heated it to about 160-170. How much does one of these steamers cost? Thank you for sharing. I'm very interested. +5 to you.

I adjust my substrate (usually homemade compost and coco coir) to field capacity _before_ I pasteurize it. Steam pasteurization allows the materials to be pasteurized without changing my moisture content at that point... I do this by loading up gusseted poly bags (cheap, $50 USD per thousand) with the hydrated substrate or casing mixture, load it up into the steamer unit and let it go.
Since the steam (212F) starts cooling the minute it leaves the boiling water, the larger the container or the more substrate you attempt to pasteurize with it, the faster it's going to drop, what you're looking for is temps around 180-190(F) within the chamber so that you can be sure the internal temps of your substrate can be stable between 140-160(F)...

takes several trial runs and heavy monitoring for the first several runs but after you find the sweet spot, it's pretty much a set-it-and-forget it solution that is a lot cleaner and more efficient to run. Sucks power like a WHORE though, especially when you're running two at once.
