The Use of Ultrasonic Energy for Cleaning Eggs

ULTRASONIC cleaning employs high frequency sound waves to build and collapse (cavitate and decavitate) thousands of microscopic bubbles within a liquid cleaning medium. The collapsing and reforming of these minute bubbles results in agitation, and a scrubbing effect on soil.The scrubbing action in a solution is accomplished by cavitation (Carlin, 1949). Sound waves, passing through a liquid, create small vacuum pockets which almost immediately collapse. The rapid implosion of thousands of these cavitations results in a scrubbing action, particularly at the interface between the product and the soil to be removed.A scrubbing action by itself, whether generated electronically or by any other means, is not sufficient. The primary purpose of agitation is to increase the physical and chemical soil-removing action of the cleaning solution. Once loosened, the soil must be held in suspension in the solution and must be kept from redeposition on the eggs. For this purpose, …
