Abstract

An improved process and apparatus for the mechanical washing of dishes wherein said objects are placed on a horizontal rack or conveyor chain over an open reservoir or wash tank (A) containing a wash liquid comprising an aqueous cleaning liquid which is pumped and sprayed through spraying device (K) placed over and/or under the rack or conveyor chain onto the dishes (C), subsequently followed by a rinse cycle wherein said washed dishes are sprayed with water optionally mixed with a rinse aid through spraying devices placed over and/or under the rack or conveyor chain, the improvement being that a bleaching and/or disinfecting agent (sanitizer) (H) is introduced into the cleaning liquid line (J) to the spraying devices and/or direct into the wash liquor in the tank before the start of the rinse cycle, thereby controlling the amount of sanitizer in the cleaning liquid at a sufficient strength.
