[0031] An automatic cleaning apparatus and/or method for periodically cleani ng a filling machine during a filling cycle without the need for human interaction to initiate the cleaning process. In some embodiments, a controller automatically initiates a cleanin g sequence at predetermined intervals. The predetermined intervals can be a time interval, such as every thirty minutes for example, or based upon filling characteristics, such as after a predetermined number of containers are filled or a predetermined amount of product has flowed through the filling machine. In some embodiments, the controller performs many operations during the cleaning process. For example, the controller can prevent containers from entering the filling machine and control the operation of a cleaning manifold. Upon completion of the cleaning operation, the controller waits a predetermined period while filing operations commence before automatically initiating the next cleaning operation.
