Well, if you're serious and the title implies you are. You need a way to chop large amounts of straw first. You definately don't want to chop an entire bale by hand. You could rent or borrow a chipper for this. Then you need to get yourself a clean 50 gal drum and a natural gas or propane burner to heat it. You will also need to fabricate a strainer of some type out of expanded steel or something similar that is strong enough to take the weight of the wet straw. This will have to welded together and a method of lifting it out of the drum incorporated. Of course it will have to fit inside. Google 'pasteurize straw oysters' or similar and you will find examples.

There is also another method that involves using hydratred lime(mason's lime) to do the actual pasteurizing instead of heat. If you search you will find info on this method.

I do it this way ...

With that much straw its recommendable to get something like a black & decker bush-hog blower/vac mulcher that can make short work of shredding the straw.

agreed Hyph, the straw will need to be chopped up first.
Now here's a thread I did on how I do it for the oysters I grow.
It's pretty simple, and there's not a lot of $$$ needed to do it.
But you'll need a burner set up and drum as relic stated.
But it really doesn't need to be 55 gal. You could go with a smaller barrel like 35 gal if thats all you can get.

good luck
