Abstract
In recovering bakers' yeast or other biological cell material from suspension, the suspension is filtered through a filter aid, in which filtration a mixture of the filter aid and filtered yeast is scraped off the bed e.g. from the drum of a rotating suction or pressure filter as a layer 0.25 mm. - 3 mm. thick, so as to expose fresh filtration surface, and the filter aid is separated from the mixture. In order to assist the separation as by sedimentation, centrifugation or filtration, the filter aid preferably has a specific gravity or settling velocity different from that of the yeast. After the separation, the filter aid is washed and returned to the filter bed, or is dried. The yeast may be further filtered on a rotating suction or pressure filter with or without any filter aid and then dried by roller- or spray-drying. Suitable preparations of the filter aid range from 0.8 to 8.0% based on the weight of the yeast. Alternatively, the filtered yeast may first be subjected to autolysis, plasmolysis and/or hydrolysis to give a yeast extract in the presence of the filter aid and this resulting mixture centrifuged to separate the filter aid. The filter aid is exemplified by starch, diatomaceous earth, siliceous marl, fullers' earth and specified proprietary products.ALSO:In recovering bakers' yeast or other biological cell material from suspension, the suspension is filtered through a filter aid, in which filtration a mixture of the filter aid and filtered yeast is scraped off the bed e.g. from the drum of a rotating suction or pressure filter as a layer 0.25 mm-3 mm. thick, so as to expose fresh filtration surface, and the filter aid is separated from the mixture.
