ABSTRACT:
A heat exchanger with a scraping cooling arrangement for fluid matter which tends to adhere to the heat exchanging surface. A pot-shaped casing is sealed by an end-plate. The casing provides for concentric interchanging of heat-exchanging parts with heat-exchanging agent flowing therethrough. At least three annular chambers are provided for processed matter to pass through. A power-driven stripping device consisting of stripping branches protruding axially and unsupported into the annular chambers with scraper bands fitting closely to the heat-exchanging surfaces, is rotatable about the axis of the casing. At least one annular chamber is, at one end, connected to the nearest outer annular chamber and is connected at the other end, to the nearest inner chamber in a circuit. The annular chambers are separated, however, in other respects, and at least one seal is formed by a gasket rotating with the stripping device. The gasket is located in a disc-shaped base chamber of the pot-shaped casing, between the bottom of the casing and a heat exchanger part of an inset.
