  • Patent number: 8425108
    Abstract: A mixing paddle for use in a conventional ice cream maker includes two vertical arms that have outer contact edges that exceed the inner diameter of the freezer bowl in which they are positioned during use. This enables the contact edges to effectively scrape ice cream ingredients from the inner wall of the bowl during use and direct the ingredients toward the center of the bowl. The mixing paddle also comprises two cross-members that have pin-wheel style shapes that move ice cream ingredients vertically during use. The combined effect of the vertical arms and the cross-members optimally and uniformly mixes the ice cream ingredients during use and ensures efficient cooling.

  • Patent number: 7231872
    Abstract: A chocolate tempering machine is digitally programmable for controlling the heating, cooling and rotation within the machine. The machine may be programmed to enable agitated, liquid chocolate to retain its proper viscosity for extended periods of time as well as minimizing the amount of porosity in the final product and by controlling bowl rotation length of time, as well as automatically increasing heat at given timed intervals. The machine includes a menu program, whereby a user can adjust and save up to twenty-six different temperature menus or more. This menu program can also be accessed to set and save desired cool down temperatures. Sensors are located such that ambient air and relative humidity can be sensed and audio/visual warnings are provided to the user when these conditions must be altered. A wear-resistant ring for leveling purposes for the machine's bowl also serves to prevent contamination of the interior of the machine.

  • Publication number: 20010030152
    Abstract: A lapping compound holding tank (60) positionable at least partially below the lapping chamber of a lapping machine. The cylindrical tank is rotatable about its axis and includes a fixed mixer and scraping assembly (80) positioned in the tank. The mixer and scraping assembly provides strong small-scale turbulence or even scraping action very close to the bottom (64) of the tank. The tank configuration enables efficient use of floor space since the tank occupies much of the same area as the lapping chamber of the machine. There are fewer potential accumulation surfaces between the lapping chamber drain and the tank. Cost and complexity of the tank is reduced. The present invention also includes an in-line compound filtration system (120) comprising an inlet section (122), a funnel portion (128) having a tubular portion (130) and an outlet (132), and a removable magnetic unit (134) having a cylindrical magnet (136).

  • Patent number: 5971602
    Abstract: A drum-type mixer having a cylindrical-shaped drum mounted eccentrically on a drive shaft that rotates the drum. A second shaft, concentric with the drive shaft, extends inside of the drum and is operatively connected to mixing devices, such as scrapers, paddles, etc. to aid in the mixing process. The mixing devices can be rotated the same direction or in the opposite direction as the rotational direction of the drum itself, and the drum and mixing devices can be driven at the same or different speeds.

  • Patent number: 4212615
    Abstract: Agglomerating apparatus in the form of a rotating drum and a method for agglomerating and controlling the size consist of carbonaceous material, such as particulate coal, finely divided char and, optionally, a binder such as pitch. Control of the agglomerate consist size distribution discharged from the drum is achieved by increasing the relative residence time of the small or growing agglomerates and by limiting contact between the large formed agglomerates and the small forming or growing agglomerates. The preferred means to insure adequate growth time for the small agglomerates consists of a plurality of annular ribs spaced about the inside wall of the drum and a cooperating scraping mechanism. The scraping mechanism comprises a plurality of scraper blades projecting radially from a rotating shaft throughout the length thereof of the agglomerate-forming section of the drum. However, at the annular paths wherein a rib is found the scraping blades are shorter in length.
