ABSTRACT:
An evacuation system including an evacuation member engages a product package and applies pressure thereto, such that a product in the product package moves toward an outlet in the product package for dispensing. A controller monitors the force applied by a driver to the product package, thereby ensuring that the pressure remains below a particular threshold to protect the integrity of the product package. The controller further monitors the evacuation member location, thereby enabling the controller to recognize when the product package is empty. The evacuation system further includes a package carrier including a pinch-off area that moves product out of an unrecoverable portion of the product package. The evacuation member may be utilized as a stand-alone device or with a primary device, wherein the primary device provides signals to the evacuation system and the evacuation system provides product to the primary device.
