Cleaning of food product moulding inserts

An installation for production of food products, said installation comprising:

• a moulding device for moulding the food products from a pumpable foodstuff mass, the moulding device comprising a movable mould member having a movable mould member base and food product moulding inserts, wherein the food product moulding inserts that are temporarily detachable from the mould member base for cleaning, wherein each food product moulding insert has:
• an outer face,
• one or more recessed mould cavities, each mould cavity defining a shape of the product, which is to be moulded, the mould cavities each having an opening in the outer face for the introduction of foodstuff mass into the mould cavity and for the ejection of the moulded product,
• an inner face,
• a permeable volume between the inner face and the one or more mould cavities, said permeable volume comprising openings opening out at the one or more mould cavities of the insert,
• such that each mould cavity of the insert is delimited at least in part by a permeable volume, to allow for, in operation of the moulding device, passing of pressurized ejection fluid from the inner face through the permeable volume to the mould cavity in order to assist release of the food product formed in the mould cavity from the insert,
• an inserts cleaning device, comprising:
• an inserts carrier configured to temporarily mount thereon multiple food product moulding inserts, that have been temporarily detached from the movable mould member base, at respective insert mounting positions,
• one or more cleaning liquid feed ducts,
• a pump connected to the one or more cleaning liquid feed ducts, the one or more liquid feed ducts leading from the pump to the mounting positions of the inserts carrier,
• a collector device for collecting cleaning liquid,
• a cleaning liquid recirculation assembly extending from the collector device to the pump,
• a filter device arranged in the recirculation assembly.
