Abstract: Apparatus for processing compressible, heat settable material, and in one embodiment, useful in producing foodstuffs including so-called tortillas made from wheat flour, comprises a step-motion, rotatable, heated drum; a curved, pivotally-mounted, heated compression plate positioned in proximity to the drum for being swung into position parallel to the surface of said drum when the drum is in the stop-phase of step motion; feed means for feeding foodstuff materials into the region between the drum and the plate when the plate is swung away from the drum; and means for conveying compressed foodstuffs away from the drum surface as it rotates in the motion phase of the step motion.
