Abstract

A bun section toaster, in the usual case, has a frame supporting several parallel chain conveyors, each conveyor being effective to advance a related bun section through the frame in physical and thermal contact with a heating element on the frame to toast the top of the adjacent bun section. At least one of the conveyors, especially for a bun section from the bun center, receives and advances a tray having an aperture over which the bun center section lies. A radiant heating element on the frame is in position to radiate upwardly through the aperture onto the bottom of the center bun section so both sides of the section are toasted simultaneously. In the usual case, the toaster simultaneously accommodates a bun top section, center section and bottom section, although in some instances there is but a single conveyor and but the center section is handled.

Claims4

Dependent claims

A toaster for a bun center section having substantially planar and parallel upper and lower surfaces, said toaster comprising:

a. a frame;
b. a conveyor on said frame;
c. a tray having an aperture therein and adapted to receive the lower surface of a bun center section overlying said aperture;
d. means including said conveyor for advancing said tray across said frame substantially in a horizontal position;
e. a contact heater mounted on said frame, said contact heater including a substantially horizontal planar lower surface vertically spaced above said tray to engage the entire upper surface of said bun center section in firm contact to impart heat to said upper surface of said bun center section as said tray advances across said frame;
f. a radiant heater mounted on said frame in close proximity below but out of physical contact with said tray to impart heat upwardly through said aperture to said lower surface of said bun center section as said tray advances across said frame;
and,
g. regulating means for energizing said contact heater and said radiant heater to toast said upper surface of said bun center section and said lower surface of said bun center section substantially equally.
