Abstract
The present invention relates to a rotary cylindrical mould member and a method for manufacturing a rotary cylindrical mould member for moulding food products suitable for consumption. One or more recessed mould cavities (21) are formed in an curved outer surface (22c) of at least one porous mould body (22), defining the shape of the products which are to be produced. An airflow-resistive skin layer is formed by plastic deformation of a cavity surface layer, having a first flow resistance. An inner volume of the porous mould body (22) between an inner surface (22i) and the airflow-resistive skin layer has a porous structure with a second flow resistance to a compressed air flow through the porous inner volume, wherein according to the invention the first flow resistance is essentially the same as the second flow resistance.
