Patent number: 7507697Abstract: A method for cleaning the surfaces of food processing equipment that are heavily soiled with food processing byproducts, such as grease, starch and proteinaceous materials. The cleaning method consists of applying two separate aqueous cleaning solutions that are mixed together.

Patent number: 6391836Abstract: A method and biological cleaning system are provided for cleaning substrate surfaces of oils and/or greases using a biological cleaning system which utilizes a pre-treatment bath and/or post-treatment bath as part of the cleaning system. The pre-treatment and/or post-treatment baths are compatible with the biological cleaning bath and during operation of the system, the used pre-treatment and/or post-treatment baths are recycled to the biological cleaning solution for biodegradation. A system is provided in which none of the pre-treatment, post-treatment or biological cleaning baths need expensive waste disposal. Replenishment pre-treatment and/or post-treatment baths as well as biological cleaning baths are added as needed to the biological cleaning system. Other treatment baths may be added directly to the biological cleaning bath with or without pre- or post-treatment for specific purposes such as a detergent phosphating bath used in the biological cleaning tank to provide a cleaned phosphated part.Type: GrantFiled: January 16, 2001Date of Patent: May 21, 2002Assignee: BioClean, USAInventors: Juan Haydu, Timothy P. Callahan, Zoltan F. Mathe, Mikael Norman

Patent number: RE38262Abstract: We have found an alkaline warewashing detergent composition that can contain a critical amount of a nonionic rinse agent that when used in automatic warewashing machines permits the use of a potable water rinse without the addition of a separate rinse agent. Sufficient residual nonionic surfactant from the alkaline detergent remains on the surface ware and internal machine and rack surfaces after washing to promote adequate sheeting in the rinse cycle. The residual nonionic surfactant on internal surfaces dissolves in the rinse water to create an effective aqueous rinse agent. The nonionic rinse agents can be a single nonionic for both foam reduction cleaning and sheeting or can be a blend of nonionic materials providing these functions. The detergent can be in the form of a particulate, pelletized or block solid.Type: GrantFiled: March 2, 2001Date of Patent: October 7, 2003Assignee: Ecolab Inc.Inventors: John J. Rolando, Terry J.
