Porous Mould Drum For Poultry, Pork, Meat-Replacement and Vegetarian Food

A rotary cylindrical mould member for moulding products from a food starting material having at least one mould body having a curved outer surface, the at least one mould body is made from a porous material with a porous structure of intercommunicating pores, the outer circumference is at least partially sealed airtight, the at least one mould body has at least one mould cavity formed in the curved outer surface and having at its porous bottom wall and/or its porous sidewall and/or its boundary a deformation layer formed by plastic deformation from a milling operation, the mould member having a gas supply which forces a fluid gas through the inner volume and the deformation layer into the at least one cavity to assist the removal of moulded products, an average flow resistance of the deformation layer is 1-30% of the average flow resistance of the inner volume.
