Fecha de publicación: 10/11/2022 Fuente: WIPO Meat The present invention relates to a rotary cylindrical mould member for moulding products from a food starting material comprising poultry, pork, meat-replacement and vegetarian food, the mould member having a longitudinal axis and an outer circumference, comprising at least one mould body having a curved outer surface, forming at least part of the outer circumference of the mould member and an opposite inner surface, wherein the mould body is made from a porous material with a porous structure of intercommunicating pores, wherein the outer circumference is at least partially sealed airtight, wherein each mould body comprises at least one cavity in which the food starting material is moulded, the cavities being formed in the curved outer surface, are defined by a boundary comprising walls and base, the cavities comprising at its porous bottom wall and/or its porous sidewall and/or its curved/contoured boundary a deformation layer formed by plastic deformation, the mould body comprises an inner volume of the mould body provided between the deformation layer and the inner surface, the mould member further comprising a gas supply which forces a gas through the inner volume and the deformation layer into the cavities to assist the removal of moulded products from the mould cavity. The present invention also relates to a method to provide a cavity in a porous mould body.
