I have been searching for a metal box to build a coffee roaster out of.
The local military surplus store has ammo cans that would be an ideal
size and heft for this but I am concerned about whether the steel they
are made out of could be used for food prep.
Does anyone know what kind of steel those boxes are made out of or how
I could find out? Just for the sake of discusion let's assume that
they can be sanitized and stripped down to the bare metal.
I've looked at stainless and galvanized but the first is very expensive
and not nessesarily better and the second is obviously not acceptable
for food prep. Mild steel should be acceptable for food prep but some
of the harder steels with tungsten in them are not.
Just an FYI, too, a coffee roaster would need to be able to withstand
at least 600F and probably up to 750F while in operation.
