  • Publication number: 20130115354
    Abstract: A method and system for homogenizing a fibrous, viscous food mass 1, in particular pasta filata, such as mozzarella, for example, wherein a feed quantity of the food mass 1 is initially fed continuously to a homogenizing device comprising a container, wherein in a subsequent step the food mass 1 exiting an outlet gap of the container is fed to a shaping and/or cooling device disposed underneath the container, wherein the shaping and/or cooling device forms a filling gap between two rollers, each of which, in particular, is equipped with a belt, and shapes the food mass 1 into a food strip, wherein the outlet gap of the container is oriented at least substantially parallel to the filling gap, wherein the opening width of the outlet gap 5 and/or the feed quantity are set such that the food mass located in the container can settle for the purpose of homogenization, wherein the fibers of the food mass entering the filling gap are aligned substantially in the processing direction.

  • Publication number: 20110287064
    Abstract: An implant is provided having an antibiotic coating that is inexpensive and easy to manufacture. The antibiotic coating adheres well and in stable manner to the surface of the implant, can be degraded by the body without forming toxic products, prevents the crystallization of the antibiotics in the coating, and ensures a high immediate locally-effective antibiotic concentration at the implant site. A coating solution useful for making the implant and a method for the manufacture of the implant are also described.
