ABSTRACT:
A foam control system is provided for eliminating foam in a process fluid system, such as foam generated in the course of blanching steps and the like involving processing of potatoes or other food products. The foam control system includes one or more capacitive type proximity probes for detecting the presence of foam in a corresponding number of process fluid systems or tanks, and for automatically supplying a spray of a selected defoamer agent to the tank. The defoamer agent spray is supplied to the tank for a selected time interval, with a portion of the spray being directed at the associated detector probe to insure clearing of foam from the probe.
