A belt conveyor comprises an endless conveyor belt and first and second rollers. The endless belt follows a conveyance path from the first roller to the second roller and a return path from the second roller to the first roller. The belt conveyor further comprises a plurality or parallel lines extending over the conveyor belt along the whole conveyance path and over and away from the second roller along a plane deviating from the plane of the conveyance path. The belt conveyor may be used in a food treating apparatus having a housing for conveyance of articles therethrough, and the housing may be used for treating, e.g. freezing, food products by impingement means.
