A heat exchanger comprises a housing jacket and tube segments disposed concentrically inside the housing jacket. Between two receiving plates, closing the housing jacket on its face ends, the tube segments embody heating chambers and product chambers. While the product to be heated flows in a meandering course through the heat exchanger, the heating medium flows through the heat exchanger over short paths from a medium inlet stub, in the direction of a medium outlet stub. The heat exchanger of the invention is distinguished by a relatively simple construction and is especially suitable for compositions in the candy industry, using steam as the heating medium.

The heat exchange of claim 2, wherein the inlet (41) for the product is disposed centrally relative to the receiving plates (12, 13) and inside the housing jacket (11) embodies a first chamber (42) for the product; and wherein the product from the first chamber (42) enters the first annular chamber (43) radially and from there passes over, also radially, into the ensuing annular chambers (44, 45), so that the outlet (46) for the product is coupled with the radially outermost annular chamber (45).5. The heat exchanger of claim 1, wherein the closure caps (47, 48) that cover the receiving plates (12, 13) are embodied convexly, so that an entrance chamber (49) and an exit chamber (50) for the heating medium are formed between the closure caps (47, 48) and the receiving plates (12, 13).6. The heat exchanger of claim 2, wherein the closure caps (47, 48) that cover the receiving plates (12, 13) are embodied convexly, so that an entrance chamber (49) and an exit chamber (50) for the heating medium are formed between the closure caps (47, 48) and the receiving plates (12, 13).7. The heat exchanger of claim 5, wherein the inlet (51) and the outlet (52) for the heating medium are disposed on the opposed closure caps (48, 49); and wherein the outlet (52) is disposed on the bottom (53) of the exit chamber (50).8.
