Abstract
A method and apparatus are disclosed for treating fresh fruit to prevent and retard the growth of fungus. The techniques of the invention include simultaneously scrubbing the fresh fruit while drenching with a falling liquid containing a fungicide. Large volumes of liquid are used and the liquid can be recycled. The liquid also removes dirt and debris and, while containing a rather small amount of fungicide, such amount is present in a concentration sufficient to apply a coating to the fruit at the end of the scrubbing step given proper pH control. The pH of the solution is controlled. During the scrubbing step, the fruit is continuously rotated to provide even fungicidal deposit.
