Abstract: A method of presterilizing an aseptic tank and connecting conduits involves pumping a certain amount of cold water into the tank and the conduits which is caused to pass through a heat exchanger. In the heat exchanger, the water is heated to 120-150° C., whereafter the water is pumped across the tank and conduits during 10-20 minutes.

Abstract: The disclosure relates to an apparatus for the evaporative cooling of a liquid product. The apparatus comprises a vacuum chamber (1) which is divided into a first, centrally positioned space (6) and a second space (7) which concentrically surrounds the first space (6). Both of the spaces (6, 7) are open towards the upper end wall (2) of the vacuum chamber (1). The first space (6) has an outlet (25) for condensed steam. The second space (7) has an inlet (11) for steamed product, as well as an outlet (12) for the product. The apparatus also includes a circulation circuit for coolant liquid. The first space (6) is extended downwards so that it extends at least as far below the bottom end wall (4) of the vacuum chamber (1) as the extent of the space (6) inside the vacuum chamber (1).

Abstract: The invention relates to an apparatus in an infuser for a liquid food product. The infuser is of the type which includes a pressure vessel (1) with an inlet (2) for the product located in its upper region and an outlet (6) for the product located in its lower region. In the product inlet (2) there is a device for dividing the product entering into the pressure vessel (1) into small droplets. The infuser also includes an inlet (8) for steam. The steam inlet (8) is disposed so that steam enters into the upper region of the pressure vessel (1) through a concentric distribution chamber (9). The distribution chamber (9) is defined by the wall (10) of the pressure vessel (1), a guide plate (11) and at least one foraminated plate (12).
