Summary: | The invention relates to a process for sterilising ultra-high-temperature treatment plants used for the heat treatment of liquid foodstuffs, preferably milk, whose shelf life is to be guaranteed over a period of approx. 6 weeks at a room temperature of approx. 25 DEG C. The aim was to reduce the energy input and the steam and water requirements necessary in the sterilisation of ultra-high-temperature treatment plants to a minimum by using essentially the sterile water for preparing sterile water by heat recovery in the returned sterile water. This was achieved according to the invention by reducing the throughput of sterile water compared with the nominal throughput of the ultra-high-temperature treatment plant down to not more than 20%, and the sterile water arriving from the balance tank in the milk line (1) which is pumped, by means of the hot-water pump (2) to the holder (6), deodoriser (7) and centrifugal pump (8, 10) and arrives at the sterile water exchanger (14) is heated in countercurrent up to approx. 135 DEG C by the return sterile water. |
