摘要：The invention relates to a device for increasing the service life of a tube-bundleheat exchanger in indirectly-heated UHT units for foodstuffs, in particular for milk or milkproducts, according to the generic part of claim 1. According to the invention, the servicelife of UHT plants of the inventive type is significantly increased and, as a desired side-effect, the cleaning process optimised and the sterilisation frequency reduced. The aboveis achieved, whereby the structure surface of the tube inner wall (3a), achieved by meansof macro-rough structures (MR) is surface treated by means of an electrochemicalpolishing method, which generates a micro-surface property (mR), structurally andenergetically characterised in a reduced tendency for the adherence of foreignsubstances, that the incident angle (?) is in the range 35 = ? = 25 degrees and that saidinner tubes (3; 3*) are provided in a UHT heater and a subsequent UHT heat retainer.
