  • Patent number: 5837980
    Abstract: Portable apparatus for use in a microwave oven removably supports and rotates a food treatment attachment simultaneously about first and second orthogonally related axes within the oven. A wheel of the apparatus frictionally engages the oven floor as the apparatus is rotated by the turntable drive mechanism of the oven. Rotation of the friction wheel imparts rotational movement to a food treatment attachment so that the attachment is simultaneously rotated about first and second orthogonally related axes.
