Currently it eats the tin can whole, dunno where it goes.

just needs an identical inventory to the new alloy smelters I think, and the output is where the tin cans go

I'm gonna have to buy tin at this rate

adding on to this, might as well include all of the sf machines that should have a gui change to match the electric ingot factory as well

Food fabricator, electric ingot factory, food compostor, Electric ingot pulverizer, all animal machines, crop growth accelerator, sawmill, perhaps freezer, might be a little too much of a buff, though.
