US 12,082,601 B2 · Peracetic acid monitoring and control system

Abstract

A food processing facility having application apparatus located within the interior space of the food processing facility for applying a PAA solution to food, a mixing container for containing a PAA solution having a PAA solution concentration, with the mixing container connected to the application apparatus for delivering the PAA solution to the application apparatus, and a PAA gas sensor, located within the interior space, for sensing a PAA airborne concentration. An actuation control system connected to the PAA gas sensor is adapted to receive a measure of the PAA airborne concentration and, when the measure of the PAA airborne concentration exceeds a reference value, changes one or more of the PAA solution concentration of the PAA solution in the mixing container, the flow rate of the fresh air ventilation system, and the flow rate of the exhaust air system.
