摘要

The invention relates to a method for operating a shell-and-tube heat exchanger (100) for heating a temperature-sensitive concentrate (P) of a food product under high pressure with the features of claim 1. It is an object of the present invention to overcome the disadvantages of the prior art and to provide a process of the generic type and a shell-and-tube heat exchanger for carrying out the process which, at a high pressure level, reduce the tendency for denaturation of the concentrate, viscosity increase in the concentrate or gelation of the concentrate and deposits thereof, and a germ-free, d. H. Ensure microbiologically perfect end product. In terms of process technology, this is achieved by: • that the flow paths of the tube bundle heat exchanger (100) acted upon by the concentrate (P) are designed in such a way that the concentrate (P) can be pressurized to a maximum of 350 bar (p); a defined flow-mechanical shear stress of the concentrate (P) an increased flow velocity (v) of the concentrate (P) in the inner tubes (300) and / or in the annular space outlet-side channel (600b) is provided, which is up to 3 m / s
