摘要
The present invention relates to a method of operating a tube bundle heat exchanger (100) for heating a food temperature sensitive concentrate (P) under high pressure according to the preamble of claim 1. The object of the present invention is to overcome the drawbacks of the prior art and reduce the tendency of the concentrate to denature under high pressure, the tendency of the concentrate to increase in viscosity or the gelation of the concentrate, and the tendency of the concentrate to accumulate. In other words, to provide a universal type method for assuring a microbially clean end product and a tube bundle type heat exchanger for carrying out the method. The flow path of the tube bundle heat exchanger (100) supplied with concentrate (P) is designed so that a pressure (p) of up to 350 bar is applied to the concentrate (P). In order to generate a constant hydrodynamic shear stress of the product (P), the flow rate (v) of the concentrate (P) increased to a maximum of 3 m / s, in the inner tube (300) and / or the annular outlet. This is achieved by the method of being fed into the side channel (600b). [Selection] Figure 4
