Patent US 8,636,017

A method of washing eggs in a manner which allows controlling the level of pollutants of the washing fluid. At least two sprayer units are located over a conveyor in which eggs to be washed travel in a conveying direction. The eggs are engaged by a brush at each sprayer station. At least two sprayer units located over the conveyor receive washing fluid, spray the washing fluid over the eggs and collect the washing fluid in a collector. The intake of washing fluid, the spraying of the washing fluid and the collecting of the washing fluid at each of the sprayer units is confined to that sprayer unit. Each sprayer unit except the farthest downstream sprayer unit receives washing fluid from the collector of the next downstream sprayer unit.
