Anordning för evaporativ kylning av en vätskeformig produkt

摘要

The invention relates to an apparatus for evaporative cooling of a liqueform 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 of the vacuum chamber (1). The vacuum chamber (1) has a conical upper portion (2). The first space (6) has an outlet (25) for condensed steam. The second space (7) has an inlet (12) for product supplied with steam as well as an outlet (13) for the product. The apparatus also includes a circulation circuit for cooling liquid. The first space (6) is lengthened downwards so that it extends at least as far below the bottom wall (4) of the vacuum chamber (1) as the extent of the space (6) inside the vacuum chamber (1).
