Zusammenfassung: | Fluid processing apparatus has a processing stretch (14) where the processing fluid is fed into the dispersion under pressure. The processing stretch (14) is defined by a perforated wall (25) with a large number of perforation holes (26). The processing fluid is fed into a distribution zone (23) which surrounds the perforated wall (25). An Independent claim is included for a dispersion processing operation where the dispersion flows through a processing stretch (14) while a processing fluid is injected into it, through the perforation holes (26) in a surrounding perforated wall (25).
Eine 15%ige Stärkedispersion wird einer Behandlungsstrecke (14) zugeführt und der Einwirkung von Wasserdampf ausgesetzt. Zu diesem Zweck enthält die Behandlungsstrecke (14) eine Lochwand (25) mit zahlreichen verteilt angeordneten Löchern (26), durch die der Wasserdampf in die Dispersion eindringt. Dadurch erfolgt ein Aufschließen der Dispersion. Die Vorrichtung eignet sich insbesondere zum Kochen von Stärkeleim |
