PROBLEM TO BE SOLVED: To reduce the tendency of a concentrate to denature and the tendency to deposit a concentrate while securing a microbiologically perfect final product in the case of increasing the economic output of a drying tower. The invention relates to a method of heating a concentrate (K) in a spray drying installation (100) according to the generic term of claim 1, an installation (100) for carrying out the method. The method and the equipment for carrying out the method reduce the tendency of the concentrate to denature and the tendency to deposit it, thereby increasing the economic yield of the drying tower, and thus the microbiologically perfect final Guarantee the product. This is achieved, inter alia, by the method characterized by the following sequence of steps (b) and (c). (B) High-pressure heating (H) the concentrate (K) at a high pressure level (p2) at an elevated spray temperature (T3) in the range 75-80 ° C. by means of a high-pressure heat exchanger (18). The high-pressure heat exchanger (18) is designed as a tube bundle heat exchanger having a plurality of inner tubes which are supplied with a heat medium (W) on the secondary side and the concentrate (K) flows in parallel, and are annular and single. Together, they form an internal channel in a circle. (C) Providing a defined shear load (S) of the concentrate (K) during or immediately after the treatment according to step (b) using the means present in the annular channel. The annular channel is connected to the internal channel when viewed in the flow direction, and has a predetermined extension length and a channel passage cross section of the course depending on the predetermined length.
