Zusammenfassung:	Disclosed is an evaporating apparatus (1) for treating viscous media and a method for evaporating volatile components from polymer solutions or melts. Said evaporating apparatus (1) comprises at least one delivery chamber (2) that is provided with a perforated bottom (3), a shell-and-tube heat exchanger (4) which is connected thereto and encompasses vertical tubes (8) and a degassing chamber (5) located adjacent thereto. Said degassing chamber (5) is provided with a discharging unit (6) for the product and a vapor escape (7) for eliminating volatile components. The tubes (8) of the heat exchanger (4) have a rectangular or elliptic cross section along the major portion of the longitudinal extension thereof.
