Steam Pasturization
    #2720118 - 05/23/04 09:46 PM (12 years, 6 months ago)

A question on steam pasturization. How long does one have to blast the goods with the steam, like 30 mins? or 90? or whut? Does anyone have any links to this info. I am doing my research on the net, but not coming up with alot at the moment.

Or maybe another question is, seed sterilization in manure, how long and whut would be the best process be. Oven, water or steam? I'm only out to kill seed in manure, nuthing else.

Thanks for the help guys.

That would be neat, how do you go about this different pasteurization technique, is it like normal pasteurizing?

yeah, except whut I am after is to know if you can pasturize via steam injection. Injecting it in to the manure and if it is effective or even possible?

Anyway werd.

Couldnt you just take a large pot and boil on high(really high) and use one of those baskets that potatos and stuff are cooked in for your poo, throw the lid on and cook the poo with steam????

Boiling water may get to hot to be considered Pasturization, but the steam above a large pot of water is pretty damn hot itself.

(dont ask me though I just cooked poo for the first time today)

There has been discussion of using a wallpaper steamer to produce the steam and hooking this up to a cooler with a wire rack to keep the material out of water that will pool on the bottom. Aparently the idea originates from an old mushroom growing book. If you're only looking to kill the seeds and not actually pasteurize then I would say just bake it in the oven until dry, keep an eye on it though, once its dry its a fire hazard. If you want to be really sure then wet it before hand and let it sit at room temp for a week or so to let the seeds germinate and then bake.

Werd,
I'm thinking of the same technology as an ole home brew still. Get a pop canister(like the hook up to pop fountian things), then stick it on the burner. The canister have 2 different outlets, one is for the CO2 to create carbonation, and the other is for the pop to come out. Maybe get some kind of box to fit a hose that will carry the steam to the box.
This is just an idea, thats all.

To Mycena: You may be thinking of something equivalent to the stage 2 pasteurisatino chamber in GGMM.

To all: I have read an interesting thread on some mush site concerning steam pasteurisation via homebrew setup. it specifically involved pasteurising compost in one of those spinning cement mixer type barrels. much of the article dealt with formulating, maintinaing, and turning the compost. it seemed like a tek thread. i'll see if i can find that again.

many use wagner wallpaper steamers, pretty cheap,
for steam pasturization
pipe it into a cooler full of straw
and blast it for an hour or so

Actually I think mycena was referring to the express composter from Bob Harris' book. The device was originally a stryo cooler with a steam hummer, used for composting. In recent years people have used wallpaper steamers and much larger containers, and as often as not used them for steam past. rather than composting.

The wallpaper steamers work well, I've seen them effectively past. containers up to 50 gallons in size and could imagine they would even work with large containers.

Dry oven past. is not recomended for manure, it will certainly burn if you don't keep it moist.

Back to the original question, how long is needed? Time required is related to temperature. Professionals use a variety of temp/time combos such as 140*F for 4 hours, 165* for 45 minutes, etc. I wouldn't exceed 180 however, and would give it at least 30 minutes depending on how densely it is packed.

I've never seen such a thread, or heard of anyone using a cement mixer. I would love to see that thread if you can find it. I'll look too, but if you can link to it, that would be fantastic!
