Abstract:
1. A process for the treatment of heat-sensitive fluid food products (P) in a system for ultra-high temperature processing (UHT system) ( 1 ), in which steam (D) directly heats the fluid food product (P) in a heating chamber to form a germ-free state, a heated food product (P*) is kept hot in a heat maintainer section for a defined and controlled period, and in which water in a quantity corresponding to that of the previously introduced steam (D) is removed in a vacuum chamber from a heated food product (P**) by means of pressure relief, characterized in that the steam heated food product (P*) is pumped from the heating chamber through a pump system into the heat maintainer section and through a pressure relief valve into the vacuum chamber, wherein the steam heated product is subjected to a predetermined pressure increase (Δp) in the pump system upstream of the predetermined, unchanging heat maintainer section, the pressure level upstream of the vacuum chamber before the pressure relief is higher than the pressure level upstream of the pump system before the pressure increase (Δp), the pressure increase (Δp) is specified in such a way that the heated food product (P**) has a system pressure (p) upstream of and directly before its pressure relief that is at least 1.5 bar greater than that upstream of the pump system pressure increase (Δp), and the system pressure (p) downstream of the pump system pressure increase (Δp) is decoupled from that upstream.
