CLEANING OF METALLIC ARTICLES

摘要

A machine and a method for removing contamination from the surface of an article comprising an aqueous wash machine (10), a cabinet (12) having a wall structure forming a plurality of work stations comprises a pre-wash compartment (14), a wash compartment (16), a rinse compartment (18), a first rinse compartment (20), air drying compartment (22), a radiant heat drying compartment (24) and an air drying station (26) separated to prevent contamination carryover from one station to the next. A demagnetizing unit (34) is mounted on the cabinet (12) to demagnetize blades. Razor blades in stacks (54) are passed through the stations and the nozzles or jets within the machine being so oriented as to cause a riffling of the blades due to water or air pressure. A purified water rinse and preferably an aqueous cleaning solution are employed in the machine and are circulated through the stations by a flow system which provides efficient and economical usage of the cleaning solution and rinse materials.
