Abstract

A roasting oven includes a housing having upper, lower, front, rear, right and left walls defining a cylindrical oven interior. The oven also includes a spit assembly rotatably disposed in the interior, at least one infrared radiation element in the upper wall facing the interior, a water cavity in the lower wall for holding water and drippings, a rotating shaft disposed between the end walls for rotabably supporting the spit assembly, and drive elements coupled to the rotating shaft for turning the shaft during roasting, in which an opening in the front cylinder is provided for inserting and removing meats to be roasted. The infrared element faces the oven interior and enables infrared radiation to be reflected from meat at the interior while curvature of the upper wall of the interior returns heated air which, together with direct radiated heat from the radiation element and the reflected radiation, creates oven temperature in excess of 800.degree. F. at a zone of compressive heating proximal to the upper wall.

Dependent claims

A roasting oven, comprising:

(a) a housing having respective upper, lower, front and rear walls, and left and right end walls, defining in combination, a hollow envelope having a curved upper surface thereof, said housing and envelope having a longitudinal axis, said housing including, within said front wall thereof, a non-closable opening for inserting and removing meats to be roasted to thereby provide a continuously uninterrupted fluid communication between an oven interior defined by said walls and the atmosphere;
(b) at least one infrared radiation element situated within said curved upper surface, said element facing said oven interior to enable infrared transmitted radiation thereinto to be reflected about said oven interior, said curved upper surface of said envelope of said housing retaining heated air to, in cooperation with direct radiated heat from said infrared element and reflected radiation therefrom, create oven temperatures in excess of 700 degrees F. within said curved upper surface of said oven housing;
(c) a flue-type conduit in fluid communication with said oven interior at a level below said curved upper surface and above said longitudinal axis of said housing;
(d) a fan, within said flue conduit, for discharging a limited quantity of air from said oven interior while allowing retention of healed air within said curved upper surface;
(e) a spit assembly journalled within said end walls of said interior, having an axis of rotation parallel with said longitudinal axis of said housing;
and
(f) drive means coupled to said rotating shaft for turning said spit assembly in an arc or rotation passing through said curved upper surface of said envelope of the oven housing.
