Abstract: A multi-flight conveyor for transporting food articles is formed in its entirety from metals and plastic materials that are approved for use in food processing. Each conveyor flight frame comprises a ladder like structure wherein two stainless steel side rails are interconnected by a plurality of longitudinally spaced support rods formed of a lubricious plastic material. A stainless steel drive shaft is journalled at one end of the conveyor in sealed bearings. All of the rods and the drive shaft are then enclosed in a stainless steel wiremesh endless belt, which is supported and lubricated by the plastic support rods. All flights are substantially identical, except for length, and are detachably rigidly secured in a vertically stacked array which is angularly adjustable relative to the horizontal.

Abstract: A combination pressing and initial baking system is provided for converting balls of dough into thin, flat discs, such as tortillas. A box-like support structure is provided having a portion of its frontal wall open and defining a mounting for a first heated pressing plate with its dough contacting face facing downwardly and disposed at a substantial angle to the horizontal. A second heated pressing plate is mounted on horizontal pivots in the box-like support structure for pivotal movement between a pressing position adjacent to and parallel with the downwardly facing surface of the first pressing plate, and a feeding position where the upper ends of the pressing plates are spaced apart to permit the insertion of a ball of dough therebetween. Movement of the second pressing plate to its pressing position effects the pressing and initial baking of the dough in a flat disc shape. The heat input to the dough disc during pressing determines the peripheral area and thickness of the resulting disc.

Abstract: A combination pressing and baking mechanism is provided for converting balls of dough into thin, flat discs, such as tortillas. The pressing unit comprises a pair of relatively pivotally movable heated pressing plates. The lowermost pressing plate is disposed at a substantial angle to the horizontal when it is in its remote position relative to the upper pressing plate. The angle of the lower pressing plate is selected to effect the gravitationally induced sliding of the pressed disc of dough off the lower pressing plate and onto a horizontally movable heating plate or disc of an oven. The horizontal velocity of the oven disc is maintained at a level equal to or greater than the horizontal component of velocity of the gravitationally discharged dough disc so as to facilitate removal of the dough disc from the lower pressing plate.

Abstract: A baking oven embodying the method of this invention comprises a plurality of vertically stacked, vertically spaced heated baking plates. Every other one of the baking plates is periodically shifted from a horizontal baking position to an inclined discharge position wherein the disc of dough slides off the respective baking plate and falls toward the next lower baking plate. During its fall, the dough disc is engaged by an inverting apparatus which deposits it on the next lower baking plate in inverted relationship, so that both sides of the dough disc are successively exposed to the heat of the baking plate as the disc traverses downwardly through the stack of plates.
