Claim:
Device for treating foodstuffs, comprising a treatment zone in which a conveyor belt is situated for conveying the foodstuffs through the treatment zone, the conveyor belt being supported by a frame and sliding rails being mounted on the frame with the conveyor belt guided on them, wherein the sliding rails are self-supporting elements, the sliding rails are made entirely of a low-friction plastic and are mounted on the frame, the sliding rails, when in an installed position on the frame, are in a fixed and movable bearing construction which fixes at least a first end of the sliding rails in position relative to the frame while permitting at least a second end of the sliding rails to move relative to the frame to compensate for differences in thermal expansion, the sliding rails have a cross-section which is essentially rectangular with a rail height greater than a rail width, and the sliding rails are placed on fixed, non-rotatable transverse bars with only two points of contact with the transverse bars.
