It appears to be some sort of part tumbler or washer.

I know it's not butter. but a vibratory cleaner,deburrer, tumbler thingy is a good answer.I hope it dont have any aluminum in there....it may get pulverized to dust...of coarse they may be making aluminum dust.:headscratch:

biscut maker
Grease trap
Looks like a big heat exchanger to me. It is really clean inside except for that nasty looking sludge.
I was joking about the biscuit maker...it does look like a heat exchanger of some sort, possiably to chill the gressee in the trap so they could pull it out and put it in the tubes for the gresse guns..:idea::headshake::gunfire::smash:
I thought the grease went to USA fast food places.
