Pan cleaning machine and a method of operating the machine to clean pans

Abstract

The invention is directed to an improved pan cleaning machine that has a cleaning section that comprises a plurality of frames for mounting a sequence of interchangeable modular cleaning mechanisms. It can include quick-release mounting arrangements so that cleaning mechanisms can be quickly changed for cleaning different types of pans or to replace brushes or other wearing parts of cleaning mechanisms when they require replacement. In some embodiments, the frames for mounting the cleaning mechanisms can comprise swing arms so that the cleaning mechanisms can be swung away from the cleaning position so that the cleaning mechanism can be removed and replaced without interrupting the operation of the machine. If the machine is stopped, the swing arm can still be used to facilitate access to the cleaning mechanism to reduce the time needed to complete the maintenance or replacement. This also allows the position of the cleaning mechanism in relation to the baking pans to be adjustable during the cleaning process which can permit increased application of brushing forces or prevent overloading and also permits easy jam removal. In addition, the swing arm makes the pan cleaning machine more adaptable for cleaning pans with different depths and customizable. A method of operation and control, including pre-programmed cleaning cycles and various control paradigms is also provided.
