Patent number: 6495183Abstract: A method for treating used cooking liquid from a cooking process includes the steps of removing a portion of the used liquid cooking medium from a cooking vessel and channeling it to a treatment vessel. The treatment vessel is sealable against a pressure that is substantially greater than atmospheric pressure. The cooking medium in the treatment vessel is then subjected to a pressure substantially greater than ambient atmospheric pressure, and it is heated in the treatment vessel to a temperature greater than an atmospheric pressure boiling point for a sufficient time to restore the cooking medium to a condition suitable for cooking. Finally the treated cooking medium is returned to the cooking vessel from the treatment vessel. This method is environmentally useful for significantly reducing wastewater production and “makeup” water usage.Type: GrantFiled: November 14, 2001Date of Patent: December 17, 2002Assignee: Howden Food Equipment Corp.Inventors: Leonard DeFrancisci, Leonard J.
