Abstract

An oven includes single or multiple decks of longitudinal burners extending from an infeed end to an outfeed end of a body. The burners are slanted relative to a direction of a movable carrier such that a product traveling on the carrier will be heated continuously from one side to the other by a burner whose orientation is diagonal to the product'"'"'s path of travel. The proportion of air and gas may be separately controlled for each deck. Furthermore, each burner may be individually controlled and monitored to maintain a desired temperature within the body. Latitudinal pilot runners extend across the width of the oven to ignite and maintain the longitudinal burners. Infrared burners above the top deck initially heat a product to either seal in or eliminate moisture. The invention further comprises a method for heating a product.

Claims

1. An oven having an infeed end, an outfeed end, and a horizontal plane, the oven comprising:

a movable carrier to support a product to be heated, the carrier being movable in a first longitudinal direction between the infeed end and the outfeed end;

a deck of longitudinal burners disposed on the horizontal plane, each of the longitudinal burners extending in a second longitudinal direction between the Infeed end and the outfeed end; and

an infrared burner disposed above the deck of longitudinal burners,

wherein the second longitudinal direction is diagonal to the first longitudinal direction.

2. An oven having an infeed end, an outfeed end, and a horizontal plane, the oven comprising:

a movable carrier to support a product to be heated, the carrier being movable in a first longitudinal direction between the infeed end and the outfeed end; and

a deck of longitudinal burners disposed on the horizontal plane, each of the longitudinal burners extending in a second longitudinal direction between the infeed end and the outfeed end,

wherein the second longitudinal direction is diagonal to the first longitudinal direction, and

wherein the longitudinal burners are oriented in a V-formation.

3. An oven having an infeed end, an outfeed end, and a horizontal plane, the horizontal plane having an X-axis in the first longitudinal direction and a Y-axis orthogonal to the X-axis, the oven comprising:

a movable carrier to support a product to be heated, the carrier being movable in a first longitudinal direction between the infeed end and the outfeed end; and

a deck of longitudinal burners disposed on the horizontal plane, each of the longitudinal burners extending in a second longitudinal direction between the infeed end and the outfeed end,

wherein the second longitudinal direction is diagonal to the first longitudinal direction,

wherein each longitudinal burner comprises a front end and a back end, the front end and back end of each the longitudinal burner defining a width span along the Y-axis, and

wherein the width span of each longitudinal burner does not overlap a width span of an adjacent longitudinal burner.

4. A method for heating a product in an oven, the oven having a right side, a left side, an infeed end, and an outfeed end, the product having a cross-dimension, the method comprising:

moving a product in a first longitudinal direction between the infeed end and the outfeed end;

placing a burner in a second longitudinal orientation between the infeed end and the outfeed end, the second longitudinal direction being diagonal to the first longitudinal direction;

adjusting a length of the burner; and

heating the product with the burner as the product moves along the first longitudinal direction.

5. A method for heating a product in an oven, the oven having a right side, a left side, an infeed end, and an outfeed end, the product having a cross-dimension, the method comprising:

moving a product in a first longitudinal direction between the infeed end and the outfeed end;

placing a burner in a second longitudinal orientation between the infeed end and the outfeed end, the second longitudinal direction being diagonal to the first longitudinal direction;

adjusting a position of a front end of the burner by moving the front end toward a right side or a left side of the oven; and

heating the product with the burner as the product moves along the first longitudinal direction.

6. A method for heating a product in an oven, the oven having a right side, a left side, an infeed end, and an outfeed end, the product having a cross-dimension, the method comprising:

moving a product in a first longitudinal direction between the infeed end and the outfeed end;

placing a burner in a second longitudinal orientation between the infeed end and the outfeed end, the second longitudinal direction being diagonal to the first longitudinal direction;

adjusting a position of a back end of the burner by moving the back end toward a right side or a left side of the oven; and

heating the product with the burner as the product moves along the first longitudinal direction.
