Title
Vorrichtung und Verfahren zur Herstellung von Emulsionen mittels Membrankoerpern
Other Title
Food or pharmaceutical emulsion mill has housing around shaft-mounted membrane units.
Abstract
Die vorliegende Erfindung betrifft eine Vorrichtung sowie ein Verfahren zur Herstellung von Emulsionen. Die Vorrichtung weist ein Gehaeuse fuer die Aufnahme einer kontinuierlichen Phase sowie eine Welle auf, die rotierend im Gehaeuse antreibbar angeordnet ist. An der Welle sind ein oder mehrere hohle Membrankoerper befestigt, in die ueber einen am oder in der Welle ausgebildeten Zufuhrkanal eine disperse Phase eingeleitet wird. Beim Emulsionsprozess werden die Membrankoerper in der kontinuierlichen Phase rotierend angetrieben. Die vorliegende Vorrichtung und das zugehoerige Verfahren ermoeglichen die Herstellung homogener Emulsionen mit geringem Energieaufwand.

EP 1262225 A UPAB: 20030129 NOVELTY - An assembly prepares an emulsion from lipophilic and hydrophilic ingredients. The assembly has a housing (1) with an inlet (2) for a first continual ingredient (9) feed and an outlet (3). The housing has a drive shaft (4) within a supply passage (5) for a second dispersed phase ingredient (8) and one or more hollow membrane units (6) within feed channels (4) and fixed to the rotating shaft. DETAILED DESCRIPTION - An assembly prepares an emulsion from lipophilic and hydrophilic ingredients. The assembly has a housing (1) with an inlet (2) for a first continual ingredient (9) feed and an outlet (3). The housing has a drive shaft (4) within a supply passage (5) for a second dispersed phase ingredient (8) and one or more hollow membrane units (6) within feed channels (4) and fixed to the rotating shaft. The shaft (4) is hollow and forms the supply passage (5) for the dispersed phase (8). The membrane units (6) are discs arranged symmetrically at intervals on the shaft, each separated from the channel (4) wall by a narrow uniform gap. AN INDEPENDENT CLAIM is included for a commensurate emulsion manufacturing process in which a charge of the continual phase is first admitted, followed by a commensurate charge of the second ingredient and mixing by membrane rotation. The emulsion mill may be operated either in continual throughput or in batch modes. USE - Emulsion mill for lipophilic and hydrophilic food or pharmaceutical ingredients ADVANTAGE - The process combines maximum droplet size distribution with minimum energy consumption.
