The ProStax USS is the most flexible automated food stacker in the ProStax line-up. While many stackers are focused on long or short portions to achieve maximum speeds, the Universal Shuttle Stacker is built to handle both long and short portions with no changeover. In keeping with its “universal” name the USS is also great for applications that need to run without paper or “bypass” the ProLeaver. By simply turning the ProLeaver and the ProStax into bypass mode, products can be sent over the system without moving line components or adding auxiliary conveyors. Many other ProStax models require paper under portions to perform optimally. ProStax USS can stack products with or without paper.
