Abstract (en)

[origin: DE19525216C1] Heat exchanger (10) heats, cooks or boils a confection, pref. a solution containing a sugar or sugar substitutes. Ends of the casing (11) are closed by head plates (13, 14). Inlets (26, 27, 28) and outlets (31, 32, 33) are provided for thermal medium. In the internal volume (16), parallel, rectangular flow channel sections (35) carry the prod., their ends sealed into the head plates. In the new design, separators (19, 20) divide the internal volume into compartments (21, 22, 23). The length of the prod. flow-path in the heat exchanger is determined by the construction of the interchangeable head plates (13, 14). Channel sections (35) with product inlets (39), have smaller height (h) and cross sectional area than channel sections (35) with product outlets (41).
