A cleaning system for the area-wise external cleaning of can blanks, with a conveyor to convey can blanks along a path of movement with a superimposed rotational movement about a rotational axis aligned transversely to the path of movement, and with a cleaning device which has a cleaning belt, the outer surface of which defines a cleaning path which extends at least in sections along the path of movement and which provides a contact between the cleaning belt and a surface area of the can blanks.

A method is provided for cleaning food product molding inserts that have been temporarily detached from a movable mold member of a molding device that is configured for molding food products from a pumpable foodstuff mass.

Systems, assemblies, and methods to enhance extraction of pyrophoric materials from a refinery apparatus may include supplying a pressurized fluid to a plurality of vacuum generators, and generating, via the plurality of vacuum generators using the pressurized fluid, a vacuum flow. A manifold may provide a flow path for the vacuum flow, and pyrophoric material may be extracted from the refinery apparatus via the vacuum flow to a material collector through which the vacuum flow passes, depositing at least a portion of the extracted pyrophoric material in the material collector. One or more of inert gas or a cooling medium may be supplied to the material collector.
