Patent number: 6988825Abstract: Vertical electromagnetic stirring is used to produce low shear, stress, turbulent and chaotic mixing of a liquid material or suspension in a container regardless of the volume or container geometry. Movement of a magnetic stir bar is controlled by multiple magnetic fields. The magnetic fields are produced by a series of sequentially or non-sequentially activated inductor coils which produce asymmetrical stirring dynamics and random motions of the stir bar, causing the liquid material to be gently and effectively mixed throughout the container. Moving the stir bar in random and irregular patterns during the stirring operation creates turbulent and chaotic mixing dynamics. The stir bars used for supporting vertical magnetic stirring are specifically designed to optimize the effectivity of the mixing process by maximizing the length of the stir bar to quickly and gently mix the materials.Type: GrantFiled: July 2, 2003Date of Patent: January 24, 2006Inventors: William E.

Publication number: 20030202420Abstract: A mixing rod of an integral metal construction from a single piece provides a unitary unit having a power chuck engaging attachment end and a stirring end. The stirring end includes a pair of lobes defined by rod segments integral with an elongated shaft, wherein the lobes outwardly project 180° from one another. Each of the respective lobes terminates at its outer ends with rounded corners and a lower terminating segment joins the opposite lobes together. The lobes have height which insures that a substantial portion of the product being stirred will be engaged by the lobes in order to develop a proper product flow insuring efficient and proper mixture.Type: ApplicationFiled: April 16, 2003Publication date: October 30, 2003Inventor: George A. Berube

Publication number: 20030133359Abstract: A mixing blade for mixing a drink in a cup having a dome-shaped lid with an opening therein is provided. The mixing blade comprises tow hollow truncated cones attached base-to-base. A top side of one cone has an opening therein for attaching to a rotatable shaft. The cone-shaped walls each have a plurality of openings therein. The mixing blade is sized to fit through an opening in the top of a dome-shaped lid. To mix a drink, the ingredients are measured and placed in the cup and the lid is placed on the cup. The mixing blade is inserted into the cup through the opening in the lid and is spun or rotated to mix the ingredients for a predetermined mixing time. After the blade is removed from the drink, the drink is served and the blade is sanitized in a sanitizing solution before being used to mix another drink The mixing blade is particularly suitable for the preparation of frozen drinks.Type: ApplicationFiled: November 6, 2002Publication date: July 17, 2003Inventor: John Bittner

Patent number: 6585405Abstract: Disclosed is a fluid mixer that mixes liquids while simultaneously promoting rapid mixing entrainment of vapor in the liquid. The device includes a vertical rotor mounted centrally on a base assembly. The rotor comprises a tube which is hollow from an open top end to a bottom closed end, having an external screw thread in a right-side configuration relative from top to bottom and one or more holes located in the sidewall of the tube at the bottom of the hollow portion of the tube, preferably located centrally between two flanking surfaces of the screw thread. The base assembly comprises a stirbar and a supporting disk which contains a ceramic magnet. The base rests on the floor of a containment vessel. A magnetic stirring motor is centrally located sufficiently close to and beneath the containment vessel as to achieve magnetic flux coupling with the base magnet. Operation of the mixer develops a liquid vortex in the liquid phase material.Type: GrantFiled: April 13, 2001Date of Patent: July 1, 2003Assignee: The United States of America as represented by the Secretary of CommerceInventors: Thomas J. Bruno, Michael C. Rybowiak
