  • Patent number: 8182133
    Abstract: A mixing apparatus and method mixes constituents of a feedstock in a vessel, utilizing a mixing blade assembly rotated within the vessel in forward and reverse directions. The feedstock engages walls of the vessel, and scraper blades are carried by the mixing blade assembly to scrape feedstock from the walls of the vessel and direct scraped feedstock to feedstock being circulated within the vessel during rotation of the mixing blade assembly in either the forward direction or the reverse direction. The scraper blades each include scraper edges and are coupled to the mixing blade assembly for pivotal movement in response to engagement with feedstock during mixing, so as to juxtapose one or the other of opposite scraper edges of each scraper blade with the vessel wall for scraping feedstock during rotation of the mixing blade assembly in both the forward and reverse directions.

  • Patent number: 7914200
    Abstract: An apparatus and method for mixing feedstock within a vessel wherein the feedstock is moved along a heat transfer surface within the vessel. A mixing blade assembly includes a mixing blade and at least one mixing blade support member moved within the vessel to sweep forward along a path of travel extending adjacent the heat transfer surface. Feedstock is circulated within the vessel by the mixing blade, and the mixing blade support member includes a mixing surface confronting the heat transfer surface. The mixing surface is spaced from the heat transfer surface and is configured such that feedstock material is squeezed between the mixing surface and the heat transfer surface so as to be subjected to mixing shear and heat transfer between the squeezed feedstock material and the heat transfer surface.
