Abstract

Verfahren zum Kühlen und/oder Gefrieren wasserhaltiger Produkte durch Direktverdampfung unter Vakuum, wobei das wasserhaltige Produkt in eine Vakuumkammer eingebracht wird und durch eine Vakuumpumpe der Kammerdruck soweit abgesenkt wird, daß Wasserdampf aus dem Produkt entweicht und durch die direkte Verdampfungskälte abkühlt und der vom Produkt abströmende Wasserdampf in einem der Vakuumpumpe vorgelagerten Zeolithbett adsorbiert wird, wobei die Evakuuierung der Vakuumkammer durch die Vakuumpumpe so auf die Adsorptionscharakteristik des Zeolithbettes abgestimmt wird, daß das Produkt den gewünschten Zustand (Temperatur, Wassergehalt ect.) erhält, aber kein Wasserdampf durch das Zeolithbett hindurch zur Vakuumpumpe strömt.
