A moulding device (200) for moulding three-dimensional products from a mass of foodstuff which is suitable for human consumption. The device comprises a pump device for pumping a mass, and a drum (202) which can be rotated in a direction of rotation by associated drive means and is provided with mould cavities (204), which mould cavities are each delimited by associated walls, a base and have an opening which lies opposite the base. The device also comprises a mass-feed component (206), which is arranged in a mass-feed position along the path for the mould, for the purpose of feeding mass to the mould cavities, which mass-feed component is coupled to the pump device for supplying the mass. Closure means (214) are provided which act downstream of a mass-feed position for the purpose of closing the filling opening of the mould cavity.
