  • Publication number: 20050266542
    Abstract: Concentrated enzyme solutions are refined by a process comprising the steps of: (A) providing a concentrated enzyme solution comprised of insoluble solids; (B) separating the insoluble solids to produce a solids-free supernatant solution and (C) contacting the supernatant solution with a strongly basic anion exchanger carried out with a bed volume of from 1 to 10 to produce a decolorized protein solution. No precipitation takes place in the process. Instead, the target enzymes remain in solution throughout the entire process, for which purpose certain concentration ranges are particularly advantageous in regard to the yield to be obtained.

  • Patent number: 6841614
    Abstract: The invention relates to a method of producing soluble polymer granules which are suitable for use in washing and/or cleaning surfactants. According to said method, an aqueous preparation of the polymer which contains at least 30% by weight polymer, optionally in admixture with other washing and/or cleaning surfactant ingredients, is granulated and at the same time dried batchwise or continuously, preferably continuously, in a circular fluidized bed. In said fluidized bed, an eddy flow about the vertical axis of the apparatus is produced above the ground of the fluidized bed by means of an air inlet. The invention also relates to soluble, spherical polymer granules with a polymer content of 50 to 95% by weight and to washing or cleaning surfactants containing the inventive granules.
