Patent number: 10357051Abstract: A method and system for removing foreign grains from oat grains to establish gluten-free oats, i.e., oat grains having gluten levels below 20 ppm and, more preferably, below 10 ppm relies upon performing a series of differentiation operations on a combination of grains, including oats and foreign, or gluten containing, grains, followed by a re-shaping operation to compress the oat grains but not the foreign grains. Thereafter, the compressed oat grains are separated from the foreign grains to establish the gluten-free oats. The resulting oats can be used to make a wide range of gluten-free oat food products, including cereal and granola products.Type: GrantFiled: November 9, 2012Date of Patent: July 23, 2019Assignee: General Mills, Inc.Inventors: Philip K Zietlow, Daniel J Winderl, Jay Romsa, Kara M Hobart, John M Hellweg, Troy D Bierbaum

Patent number: 8708158Abstract: A material Separator with a hopper, a rigid helically shaped tubular pipe structure, an inlet port, a large particle outlet port and a small particle outlet port. The helically shaped tubular pipe structure connected to the underside of the hopper. The helical pipe structure has an internal false bottom. The false bottom is perforated so that particles that are larger than the perforations flow down the upper portion of the helical tubular pipe structure and material particles that are smaller than the perforations drop through the perforations and flow down the lower portion of the helical tubular pipe structure. The larger material particles exit the large particle outlet and the smaller material particles exit the small particle outlet. A preferred embodiment includes the helical tubular pipe structure is constructed of a plurality of curved pipe members, each having flanges at each end so that one the flanged curved pipe member can be bolted to the adjoining flanged curved pipe member.Type: GrantFiled: May 18, 2012Date of Patent: April 29, 2014Inventor: Michael Joseph Erdmann

Patent number: 6755307Abstract: A device for separating undesirable oblong and/or curved pieces of scrap from a scrap flow or scrap pile with a higher density, such as chill scrap, by means of an oscillating or shaking screen (1) includes a screen base (2) with a plurality of parallel guide bars (4) running in the longitudinal direction and a plurality of separating bars (3) which present openings (3.2) whose longitudinal and transverse cross-sections have different geometric shapes.Type: GrantFiled: April 1, 2002Date of Patent: June 29, 2004Assignee: Metso LindemannInventor: Erich Köhl

Patent number: 4378186Abstract: The device allows the broaching of thin-walled workpieces with high precision and an excellent surface condition. It comprises mainly a fixed support defining a radial abutment surface, a sleeve defining ramps, wedge-shaped members bearing against said ramps and against the outer surface of the workpiece. These wedge-shaped members are carried by a plate which is capable of being brought to a wedging position under the effect of springs or to a disengaged position by means of ramps.Type: GrantFiled: December 12, 1980Date of Patent: March 29, 1983Assignee: Glaenzer SpicerInventor: Orain M. Alexandre

Patent number: 4194970Abstract: A method and apparatus for use in separating oversize from on size particles in a mass of particulate materials passed rapidly through a screening device includes a sloping screen mesh having sizing openings dimensioned to be larger than the desired maximum on size particles intended to pass through the mesh. The screen mesh is supported at a relatively steep slope angle and the cosine of the angle of the slope multiplied times the mesh opening size is set up to be substatially equal to the desired maximum on size particles to be passd through the screen mesh. A particle rebound shield is spaced at a distance in the range of 1.25 to 3 times the diameter of the largest particles fed to the screen above the upper surface of the screen mesh for reflecting and directing particles that bounce off the screen mesk back towards the openings therein.Type: GrantFiled: August 21, 1978Date of Patent: March 25, 1980Assignee: American Colloid CompanyInventor: Arthur G. Clem

Patent number: 4124920Abstract: Apparatus and method for vibrating edible crab meat from the core portion of a crab body that has been de-shelled, de-legged and de-fingered and the central core portion of which has been cleaned. The crab body is supported in a core box with the body cavity directed downwardly opposite a discharge opening formed in the bottom of the core box, whereupon the core box is vibrated at about 1500 to 5000 vibrations per minute to shake the crab meat from the core and to deposit the meat particles on an endless conveyor that travels therebeneath. Preferably the core box bottom contains a plurality of pockets having walls converging toward the discharge openings, the crab cores being held in place by suitable cushion means.Type: GrantFiled: October 29, 1976Date of Patent: November 14, 1978Assignee: Sea Savory, Inc.Inventors: Richard T. Wenstrom, Theodore S. Reinke, Calvert B. Tolley, J. Clayton Brooks
