| 摘要 |
The present invention relates to an apparatus for the evaporative cooling, or flash cooling, of a liquiform product. The apparatus includes a vacuum vessel (1) which is divided into a first (6) and a second (7) space. The two spaces (6, 7) are concentrically disposed in the vessel (1).In the first space (6) an inlet (9) is disposed for steam-charged product, as well as an outlet (10) for the product. In the second space (7), there is provided a spillway overflow (14) for the condensed steam and uncondensable gases.The apparatus also includes a circulation cycle for coolant liquid, comprising an outlet (18) for the coolant liquid, a centrifugal pump (20), a cooler (22) and conduits (19, 21, 24) as well as means for distributing the coolant liquid (25, 29) in the second space (7) in the vacuum vessel (1).
