INSTALLATION AND METHOD FOR MOULDING FOOD PRODUCTS WITH A PRESSURIZED AIR FOOD PRODUCT EJECTION SYSTEM FROM A MOULD DRUM

A moulding installation and method for moulding food products from a pumpable foodstuff mass. A revolving mould drum is provided with multiple mould cavities and a mass feed member is arranged at a fill position to transfer foodstuff mass into passing mould cavities. Said foodstuff mass forms a food product in said mould cavity. A pressurized air food product ejection system comprises air ducts in the mould drum that extend to said cavities and at least a portion of the surface delimiting a mould cavity is air permeable. Said ejection system further comprises a pressurized air source to feed pressurized air at a regulated ejection air pressure thereof to said air ducts. A controller is adapted to input at least one target parameter related to filling of the mould cavities with said foodstuff mass via said mouth of the mass feed member. The controller is adapted to automatically set an ejection air pressure by said pressurized air source on the basis of the inputted target parameter.
