ABSTRACT:
A sanitary concentric tube heat exchanger for cooling or heating flowable or pumpable products is disclosed. In one embodiment, two concentric tubes are sealed together with inlet and outlet openings. The product is allowed to flow through the outer of the two tubes while the heating or cooling medium flows through the inner tube. In another embodiment, a third concentric tube surrounds the product tube and is used for the flow of additional heating or cooling medium. A securing clamp open on one end of the product tube secures the product tube to the outer surface of the inner tube and can be easily dismantled for cleaning purposes. A seal assembly secures the other end of the product tube to the outer surface of the inner tube and permits relative movement between the inner tube and the product tube for accommodation of thermal effects during operation, and also to allow the asembly to be easily dismantled for cleaning or inspection.
