A heat exchanger (10) comprises a housing jacket (11) and tube segments (14-20) disposed concentrically inside the housing jacket (11). Between two receiving plates (12, 13), closing the housing jacket (11) on its face ends, the tube segments (14-20) embody heating chambers (21-24) and product chambers (42-45). While the product to be heated flows in a meandering course through the heat exchanger (10), the heating medium flows through the heat exchanger (10) over short paths from a medium inlet stub (51), in the direction of a medium outlet stub (52). The heat exchanger (10) 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.
