In a brightly lit, sparse room, an older man dressed in a green jumpsuit is operating a large, blue-painted machine. The machine consists of a hopper that feeds a round, elevated pan. The pan is supported by a small wooden stool and discharges onto a series of angled vibrating trays and rollers, all powered by a visible electric motor. A large pile of white powder has accumulated on the floor beneath the machine. The man is shown observing the process, and in the background, there is a white bag labeled "BUA" and a utility outlet on the wall. The overall impression is of a manual operation in a small-scale industrial or agricultural setting.
