Application of a release agent onto the interior surfaces of a commercial bakery trough is accomplished by a system for dispensing a gel having two spray head assemblies. While the trough is stationary, each head in turn descends into the trough and propels the release agent onto a portion of the interior surfaces including side walls, an end wall, and the bottom wall of the trough. Each head includes a disc that spins to distribute the release agent. An edge on the disc defines a predetermined spray pattern. Waste of release agent due to overspray is minimized by controlling a release agent valve in the head, controlling disc rotation, and monitoring position of the head in the trough.
