Apparatus for coating a foodstuff with particulate material includes a drum capable of rotating about a substantially horizontal longitudinal axis, and two horizontal conveyors, one positioned above the other, adapted to travel longitudinally in opposite directions through the drum. The lower conveyor has at least three successive endless conveyor belts having horizontal upper runs and a gap between each successive pair of belts. The second belt has an inclined portion below the first belt and the gap between the second and third belts is situated within the horizontal drum. The apparatus also contains means for feeding particulate material onto the upper conveyor and means for feeding the foodstuff onto the first belt of the lower conveyor. Particulate material is transferred from the upper conveyor onto the foodstuff on the first belt, excess particulate material falls off the forward end of the first belt onto the inclined portion of the second belt and is conveyed to the horizontal portion of the second belt to form a layer on which the foodstuff lies after being transported from the first belt to the upper run of the second belt, and further excess particulate material falls through the gap between the second and third conveyor belts onto the lower part of the inside wall of the horizontal drum from where it travels upwards on the inside wall until it reaches a position above the upper conveyor onto which the particulate material falls by gravity.
