A commercial baking dry pan cleaning system is provided having a support frame with one or more modular swing arms mounted thereto. One or more controllers is provided to control the one or more modular swing arms. One or more unclean pan conveyors provides a stream of unclean baking pans to the system. The controller engages one or more actuators to operate the one or more modular swing arms which swing around one or more pivot points to swing a cleaning subsystem or module into contact with the unclean stream of pans. A position limiter is coupled to each of the swing arms to set an initial operating position. The limiter communicates with the controllers. The cleaning subsystem is swung into position on the modular swing arm to engage the unclean pan. The controllers are adapted to sense and control a pressure exerted by the cleaning subsystems on the pan and maintain pressure within a pressure range. The controller whilst sensing the pressure exerted on the pan can also sense certain error conditions thereby disengage the pan if the sense pressures are outside of ranges.

A method of operating a pan cleaning system is disclosed in which cleaning parameters are sensed to identify the type of pan being processed. Based on the identified type, a predetermined cleaning routine is automatically selected. Cleaning mechanisms are selectively activated and engaged with the pan, while non-selected mechanisms remain out of service. The system adjusts cleaning speed, motion, and spacing in response to the selected routine and real-time sensor data, including compensating for warped pans. The method further enables servicing of inactive cleaning mechanisms and control of actuation through swing-arm-mounted devices, improving efficiency, adaptability, and maintainability of the cleaning process and the system.
