Abstract
A sanitization system for sanitizing a convey line broadly includes an ozone generation and delivery module, a compressed air source, and an air flow control system, and an ozone measurement and destruction module. The ozone generation and delivery module includes ozone generator, an ozone flow meter, a first ozone analyzer, a humidifier, and a humidity sensor and introduces a measured ozone gas stream into the convey line so that the ozone disinfects the inner surfaces of the convey line. The humidifier introduces moisture into the convey line to increase the effectiveness of the ozone as a disinfection agent. The ozone measurement and destruction module includes a second ozone analyzer, an ozone destructor, and an ozone monitor and removes ozone from the gas stream. The ozone measurement and destruction module also ensures that a desired amount of ozone reaches the end of the convey line.
