- 30 - ABSTRACT The description concerns a method for ensuring constant product quality and product safety when tailback conditions occur in pasteurisers and a configuration for the implementation of the method, the intention being to ensure that, in pasteurisers operated on a throughfeed principle, overpasteurisation and also underpasteurisation in the event of a tailback are reliably prevented and pasteurisation kept within very narrow tolerance limits (PE limits). For this purpose it is proposed, inter alia, that in the pasteuriser, which is operated at a constant throughfeed speed suitable to satisfy regular pasteurising requirements, a cooling process should be performed when the tailback begins, cooling over its width of action the relevant section of the pasteurising zone to a temperature which allows no increase, or a slight increase not exceeding the tolerance, in the number of pasteurisation units (PE) applied in that section to the product up to that time, the final position and time of action of the cooling process being determined by the tailback time ts. A proposed configuration for implementing the method provides for fixed spray pipes (5) or swivel-type nozzle systems (5a) for the purpose of applying cold water to be located along the zones which are capable of being switched on and off separately in such a way that, inter alia, the progression of the cooling process is performed in sections, without interruption, in progressive sequence and as determined by the step time ?t (Figure 4).
