Directly before filling, different additives are continuously mixed into a "master batch". Depending on the recipe, these could be enzymes, glycerine, perfumes, brighteners and many other components. The special feature of the mixers is the large number of product inputs in the mixer housing. Depending on the recipe, up to twelve media can be fed into the mixer. A hygienic mixer design with polished surfaces and flushed mechanical seals is a matter of course for this type of application. The mixers were manufactured in two batches of six and, as usual, shipped punctually on the respective shipping date.
