An oven includes a conveying interior for moving produce through the oven and a gas fired heat source for cooking the produce conveyed through the oven. The conveying interior preferably comprises a rotating drum with a conveying spiral extending inwardly from an inner wall of the rotating drum. The rotating drum may further be sloped downward to facilitate progress of the produce through the oven, and the time spent in the oven may be controlled by controlling the rotating rate of the drum. The gas fired heat source may comprise a thermostatically controlled burner residing under the drum.

I claim: 1. A continuous feed oven comprising: an oven housing; a rotating drum inside the oven housing; an oven entrance, the oven entrance configured to remain partially open during oven operation to allow raw produce to enter the rotating drum while earlier entering produce is being cooked; an entrance door residing over the oven entrance and having an open position, and a closed position, the closed position allowing a minimum access to the oven entrance, the entrance door denying access to a top half of the oven entrance, and the entrance door leaving a bottom half of the oven entrance open in the closed position of the entrance door to allow raw produce to be fed into the oven entrance during operation of the oven while earlier produce is being cooked within the oven; an oven exit, the oven exit configured to remain partially open during oven operation to allow cooked produce to escape the rotating drum while later entering produce is being cooked; an electric motor for rotating the drum; a mechanical connection rotationally connecting the electric motor to the drum; a gas fired heat source inside the housing and producing a flame under the rotating drum; and a thermostatic control for controlling the gas fired heat source. 2. The oven of claim 1, further including a continuous conveying spiral inside the rotating drum for advancing produce through the rotating drum. 3. The oven of claim 1, wherein the rotating drum includes a drum entrance and a drum exit, and the rotating drum is sloped downward from the drum entrance to the drum exit. 4. The oven of claim 3, wherein the rotating drum is sloped downward at approximately 3.3 degrees. 5. The oven of claim 1, further including a temperature probe residing at least partially inside the rotating drum, and wherein the thermostatic control receives temperature measurements from the temperature probe. 6. The oven of claim 5, wherein the thermostatic control turns the gas fired heat source on when the temperature measurement is below a lower temperature and turns the gas fired heat source off when the temperature measurement is above an upper temperature. 7. The oven of claim 1, wherein: the entrance door covers approximately the top half of the oven entrance in the closed position of the entrance door to reduce the escape of heat from the oven while allowing raw produce to be fed into the oven entrance during operation of the oven while earlier produce is being cooked within the oven. 8. The oven of claim 7, further including an exit door residing over the oven exit and having an exit door open position and an exit door closed position, the exit door leaving a gap G at the bottom of the exit door in the exit door closed position to reduce the escape of heat from the oven while allowing raw produce to be fed into the oven entrance during operation of the oven while later produce is being cooked within the oven. 9. The oven of claim 1, wherein the rotating drum is approximately ten feet long and approximately 28 inches in diameter. 10. The oven of claim 9, wherein a conveying spiral resides inside the rotating drum fixedly attached to an inner surface of the rotating drum, and the conveying spiral extends approximately four inches radially into the rotating drum. 11. The oven of claim 9, wherein consecutive 360 degree loops of the continuous conveying spiral are spaced approximately 10 inches apart. 12. The oven of claim 9, wherein the rotating drum includes a drum entrance and a drum exit and the drum exit is approximately seven inches lower than the drum entrance. 13. The oven of claim 9, wherein the electric motor is a variable speed electric motor. 14. The oven of claim 9, wherein the gas fired heat source includes a blower for mixing air with gas to produce the flame under the rotating drum. 15. A continuous feed oven comprising: an oven housing; a rotating drum inside the oven housing, the rotating drum having: a drum entrance configured to remain partially open during oven operation to allow raw produce to enter the rotating drum while earlier entering produce is being cooked; and a drum exit configured to remain partially open during oven operation to allow cooked produce to escape the drum following being cooked and while later entering produce is being cooked, the rotating drum sloped downward from the drum entrance to the drum exit at between approximately two degrees and approximately five degrees slope; an entrance door pivotally attached above the drum entrance and pivotable between an open position and a closed position, the closed position allowing a minimum access to the drum entrance, the entrance door leaving a vertical gap between a bottom edge of the entrance door and the bottom of the drum entrance in the closed position of the entrance door to allow raw produce to be fed into the drum entrance only through the vertical gap during operation of the oven while earlier produce is being cooked within the oven; a continuous conveying spiral inside the rotating drum for advancing produce through the rotating drum, the conveying spiral fixedly attached to an inner wall of the rotating drum; an electric motor for rotating the drum; a gas fired heat source producing a flame under the rotating drum, the heat source comprising: a gas source; a blower for mixing air with gas provided by the gas source to produce a gas and air mixture; and a burner residing under the rotating drum for burning the gas and air mixture; and a thermostatic control for turning the gas fired heat source on and off. 16. The oven of claim 15, wherein; the rotating drum is between approximately six feet and approximately 14 feet long and approximately 24 inches to approximately 36 inches in diameter; the drum exit is approximately four inches to approximately twelve inches lower than the drum entrance; the conveying spiral extends approximately three inches to approximately six inches radially into the rotating drum; and consecutive 360 degree loops of the conveying spiral are spaced approximately six inches to approximately 14 inches apart. 17. A continuous feed oven comprising: an oven housing; a rotating drum inside the oven housing, the rotating drum having: a drum entrance configured to remain partially open during oven operation to allow raw produce to enter the rotating drum while earlier entering produce is being cooked; and a drum exit residing lower than the drum entrance and configured to remain partially open during oven operation to allow cooked produce to escape the drum following being cooked and while later entering produce is being cooked, and a continuous conveying spiral inside the rotating drum for advancing produce through the rotating drum, the conveying spiral fixedly attached to an inner wall of the rotating drum and extending approximately three inches to approximately six inches radially into the rotating drum and consecutive 360 degree loops of the conveying spiral are spaced approximately six inches to approximately 14 inches a part; the rotating drum sloped downward from the drum entrance to the drum exit at between approximately two degrees and approximately five degrees slope; a moveable entrance door hinged at the top for opening and having an open position and a closed position and configured to cover only an approximately top half of the drum entrance when the entrance door is in the closed position; a moveable exit door hinged at the top for opening and configured to cover substantially all of the oven exit when the exit door is closed, leaving a gap to allow cooked produce to escape the oven; an electric motor for rotating the drum; a gas fired heat source producing a flame under the rotating drum, the heat source comprising: a gas source; a blower for mixing air with gas provided by the gas source to produce a gas and air mixture; and a burner residing under the rotating drum for burning the gas and air mixture; and a thermostatic control for turning the gas fired heat source on and off. 18. The oven of claim 17, wherein; the rotating drum is between approximately six feet and approximately 14 feet long and approximately 24 inches to approximately 36 inches in diameter; and the drum exit is approximately four inches to approximately twelve inches lower than the drum entrance. 19.
