Abstract
Abstract A machine is described for selectively coating a baking pan or baked goods with different liquids, as for example, grease, egg wash and glazing, in a rapid manner without the risk of contamination of one material by the other. The machine comprises a trough supporting a perforated pan support covered by a lateral housing containing a spray head. With one of the liquids recirculation is from the trough to the spray head. For a different liquid an insert is provided on top of the pan support which isolates it from the sidewalls of the housing and a separate container is caused to recirculate the different liquid.

Claim 1
Independent Claim
178 words
A machine for selectively applying different liquids to a baking pan or the like, comprising a frame, a trough (9) supported by said frame, a pan support member (11) comprising a perforated corrugated place, a housing (5) defining a laterally closed volume with said support member (11) and adapted to receive a removable insert member (12), a spray head (22) mounted in said housing (5), means for causing liquid in said trough (9) to move to said spray head (22), at least one separate container (21) for a different liquid, means for causing said different liquid to flow to said spray head (22), and means to permit flow of said different liquid from said insert (12) to said container 21; said pan support member (11) being characterized in that liquid applied to it will flow through to said trough (9); said removable insert member (12) being provided with a solid bottom wall and side deflectors (13) so as to isolate the flow of said different liquid from said spray head (22) from the sidewalls of the housing (5).
