Abstract
A heat exchange system utilizing flow reducers at 180 degree bends in the tubes includes a first set of media tubes in which heating/cooling media flows, and a set of product tubes positioned concentrically within the media tubes and in which liquid product flows in a counter direction to the heating/cooling media. The tubes are arranged in a serpentine, back and forth manner, and U-shaped tubes interconnect successive pairs of product tubes to achieve the 180-degree change in flow direction. The U-shaped tubes are of a cross-sectional diameter greater than the product pipes. Tapering flow reducers extend between the opposing ends of the U-shaped tubes and the product tubes. The exit flow reducer is eccentrically formed to facilitate a smooth transition of the product from the U-shaped bend to the product tube and prevent liquid product from becoming entrapped along the bottom of the flow reducer.
