Abstract: A conveying system for food processing such as cooling pouches of food discharged in a single line from a pouch filler including apparatus for rearranging the pouches in order to shorten the line. One apparatus is a right angle transfer device in which the pouches are discharged in a single line onto a belt array which is then dropped to allow an array of rollers to support the pouch and transfer its direction of motion. Another apparatus includes an array of rollers which move the pouch into a position forming a row of pouches which is then picked up by rollers and moved in a direction as a line of rows of pouches. Another apparatus is a belt system for supporting the row of pouches as it is being transferred from a downstream end of an upper conveyor to an upstream end of a lower conveyor thereby reversing the direction of motion of the pouches and allowing them to pass back through the treatment chamber.
