Description

Verfahren zum Waschen von Hefe Es ist bekannt, daß man die zum Anstellen von Bierwürze zu verwendende Hefe wäscht, und zwar sowohl durch einfaches Aufschlämmen und Absitzenlassen in Wannen wie auch in besonderen Hefewaschapparaten, die zum Teil auf demselben Prinzip des Schlämmens und Albsitzens beruhen. Beim Waschen der Hefe handelt es sich um die Entfernung von Trubbestandteilen, hauptsächlich Eiweißgerinnsel und Hopfenharze. Diese Stoffe sind oft sehr stark an einzelne Hefezellern, oder an Konglomerate von Hefezellen adsorbiert; so daß ein einfaches Schlämmen nicht ausreicht, um sie abzulösen.Method for washing yeast It is known that one can use the method for wetting of wort washes yeast to be used, both by simple slurry and settling in tubs as well as in special yeast washers designed for Partly based on the same principle of slouching and sitting down. When washing the Yeast is used to remove sediment, mainly protein clots and hop resins. These substances are often very strong on individual yeast cells, or adsorbed on conglomerates of yeast cells; so that a simple mud does not enough to replace them.

Als neu wurde nun gefunden, daß man durch Einwirkung von hörbarem Schall mit oder ohne Luftimpuls, wie er erzeugt wird z. B. a) durch das Schallwaschgerät Ultrakost Pulsette (Ultrakost G. m. b. H., Ruhmannsfelden/Niede@rbayern. oder b) durch den Bosch-Schallwäscher (Robert Bosch G. m. b. H., Stuttgart) oder c) durch ähnliche Geräte, die es gestatten, die Wellenbewegung des Schalls und damit seine dispergierende Eigenschaft auf Flüssigkeiten zu übertragen, auf Hefeaufschlämmungen eine sehr rasche und weitgehende Befreiung der Hefe von anhaftenden Trubstoffen bewirken kann, so daß eine auf diese Weise ge- waschene Hefe infolge der Entfernung der die Zellmembran verklebenden Trubstoffe eine bessere Gärleistung ergibt als eine anders behandelte Hefe und daß außerdem die Hefe durch die Kürze des Waschvorganges weniger geschwächt wird als lange gewaschene Hefe.As new it has now been found that by exposure to audible sound with or without an air pulse, as it is generated z. B. a) by the sonic washer Ultrakost Pulsette (Ultrakost G. mb H., Ruhmannsfelden / Niede @ rbayern. Or b) by the Bosch sonic washer (Robert Bosch G. mb H., Stuttgart) or c) by similar devices that make it possible to transmit the wave motion of the sound and its dispersing property to liquids can cause a very rapid and largely freed of yeast adhering sediments on Hefeaufschlämmungen so that a overall in this way washed yeast, due to the removal of the cell membrane bonded Trub materials give a better fermentation performance than yeast treated differently and that, in addition, the yeast is less weakened than yeast that has been washed for a long time due to the shortness of the washing process.

Aus f ührung.sb-ei sp iel Die zum Waschen bestimmte Hefe, z. B. Bierhefe, wird in einer Wanne oder in einem sonstigen hierzu dienenden Gefäß mit Flüssigkeit, z. B. mit Wasser, aufgeschlämmt und z.. B. 30 Minuten mit einem Schallgerät, wie, unter ,a), b.) und c) beschrieben, behandelt. Nach dieser Behandlungsdauer läßt man die Hefe absitzen und entfernt das überstehende Reinigungswasser. Die Hefe kann wiederholt nach diesem Verfahren behandelt werden, his durch mikroskopische Prüfung einer Hefeprobe festgestellt wird, daß die Reinigungswirkung ausreichend und gut ist.Aus f ührung.sb-ei sp iel The yeast intended for washing, e.g. B. brewer's yeast is in a tub or in another serving vessel with liquid, z. B. with water, slurried and, for example, 30 minutes with a sound device, as described under, a), b.) And c), treated. After this treatment period, the yeast is allowed to settle and the excess cleaning water is removed. The yeast can be treated repeatedly by this method until it is determined by microscopic examination of a yeast sample that the cleaning action is sufficient and good.
