According to the invention, the object of the method and the appartus associated herewith is to avoid the disadvantages which arise in a plate pasteurizing apparatus for the pasteurizing of a liquid product in a continuous flow during and after a stop in production. When pasteurizing with known plate pasteurizing apparatus, the product is led through a holding pipe, which has the disadvantage that the temperature in this holding pipe cannot be controlled during a possible stop in production. Therefore, in existing apparatus it is necessary to have a large buffer tank which can contain 1/2 - 1 hour's production, which is very space-demanding. Production in excess of this interval is wasted. According to the invention, this problem is solved by providing each individual zone (6) in the pasteurizing area with a connection (16) for heating (19) and/or cooling (20) of the product, so that in the event of a stop in production it is possible to hold the temperature below the pasteurizing temperature, and upon re-starting to heat the product again to a temperature close to the pasteurizing temperature. |
