Patent ID: 7988792

Claim:
A method for automatically washing eggs, comprising the steps of: dispensing a detergent-wetting agent mixture onto the eggs through a sprayer by an apparatus that separately dispenses an aqueous electrolyte alkaline detergent and a wetting agent to form the mixture, the apparatus comprising: a holding tank containing the mixture; a circulation pump having an input tube connected to the holding tank and an exit connected to the sprayer; a detergent pump for dispensing the aqueous electrolyte alkaline detergent into the input tube; and (c) a wetting agent pump for dispensing the aqueous wetting agent into the input tube; wherein the mixture in the holding tank is continuously circulated through the input tube and sprayer and maintained at a substantially constant effective cleaning concentration of electrolyte alkaline detergent and aqueous wetting agent by dispensing the aqueous electrolyte alkaline detergent and the wetting agent into the input tube; and wherein the detergent pump is controlled by a probe that measures the concentration of the electrolyte alkaline detergent in the input tube and the detergent pump is synchronized with the wetting agent pump and the aqueous electrolyte alkaline detergent and wetting agent are dispensed into the input tube at a predetermined ratio.
