ABSTRACT:
An apparatus and method for controllably applying a liquid substance to the surfaces of a plurality of discrete fruit moving along a path at a selected rate of speed and in accordance with the quantity of fruit on said path, the application of liquid substance to the fruit being by more than one nozzle movable transversely over the path at a selected rate of speed. The apparatus includes sensors for determining the speed of advancement of the fruit, that is the speed of the conveyor, a plurality of fingers engageable by the fruit to determine, by absence of engagement of fruit, the quantity of fruit moving along the path, and a control system for regulating the amount of liquid discharged from the nozzles and to correlate the amount of liquid discharged to the speed of advancement of the fruit and the quantity of fruit being advanced. In the method, an optimum effective volume of liquid substance is applied at selected pressures to the sensed quantity of fruit on the path.
