  • Patent number: 10736466
    Abstract: Rice-washing work can be easily performed by anyone, and proper rice-washing of various kinds of rice can be performed irrespective of an amount of rice. Namely, conventional apparatuses have not dealt with water absorption, infiltration, swelling, weakening, dissolving, and unpleasant taste, making it difficult to secure Japanese style rice quality in a white rice state. The present invention provides a rice-polishing technique for reproducing the quality. Provided is a rice washer that can be installed in a saved space not to cause obstruction even when installed in a kitchen. The rice washer according to the present invention includes a charging part into which milled rice is charged; a pressurized-stirring part provided at a rear-stage of the charging part and configured to, while pressurizing, stir and sequentially feed the milled rice charged from the charging part; a first water supply part configured to supply water to the pressurized-stirring part.

  • Patent number: 10240685
    Abstract: A secure valve access system includes a cover mounted over the valve stem of a valve. The cover is attached to a support which is mounted on the valve so the cover cannot be removed. Fasteners extend through the support and are selectively jammed against a wrench flat thereby providing a torque transmitting connection between the cover and a valve operator. Retraction of the fasteners breaks the torque transmitting connection allowing the cover to free wheel thereby preventing unauthorized operation of the valve. Rotation of the fasteners is done by an unusual drive socket.

  • Patent number: 7771767
    Abstract: A cutter assembly for an extruder includes an elongated extrusion member having an open feed end. The open feed end is attachable in fluid communication with a manifold of the extruder for supplying a mash thereto. An extrusion die is supported on the elongated extrusion member. The extrusion die includes a plurality of extrusion outlets formed therein. A cutter member cuts extrudate to a desired length as the extrudate exits the die. The cutter member is slidable on the extrusion member in a direction of elongation of the extrusion member. The cutter member is operably connectable at the drivable end to a drive device of the extruder for reciprocatably sliding the cutting surface of the cutter member over and away from the extrusion die. The shape of the extrusion outlets twist the mash as the mash exits the extrusion die in order to form a twisted food product.

  • Patent number: 7771635
    Abstract: A melt cooler and valving system for an underwater pelletizer has a diverter valve that facilitates multiple modes of melt processing. The cooler has a cooler inlet line that conveys the melt to the cooler, and a cooler outlet line that conveys the cooled melt from the cooler. The diverter valve is configured to convey the melt to and from the cooler during a cooling mode of operation, to convey the melt around the cooler during a bypass mode of operation, and to drain the melt from the cooler and the diverter valve during a drain mode of operation. The diverter valve is compact and therefore contains a minimum of product inventory. The valve is streamlined and direct in its bypass mode, and includes a drain capability to allow for faster, easier cleaning of the process line, which in turn provides a fast changeover time with less lost product.

  • Patent number: 7730817
    Abstract: A cutting apparatus for ductile materials comprises a nozzle having a number of outlet openings separated from each other by separator webs. Next to the nozzle, a rotating cutting tool is provided, having a plurality of cutting knives for cutting off the strands of material discharged through the outlet openings of the nozzle. Each separator web is at least as wide as a cutting knife. For performing a cutting operation, the cutting tool is intermittently rotated. Between two cutting operations, the cutting tool is stopped, whereby its knives remain in a rest position behind the separator webs. For the next cutting operation, the cutting tool is rotated by such an amount that its cutting knives move from a position behind a first separator web to the next adjacent separator web.

  • Patent number: 7621736
    Abstract: An apparatus for placing a mold charge into a cavity includes a pair of hubs mounted for rotation around parallel axes, a link connected between the hubs at positions off-center relative to the parallel axes and a blade connected to the link. Rotation of the hubs causes the blade to travel in an elliptical path relative to an extrusion orifice to cut mold charges from the orifice and place the mold charges into cavities passing beneath the blade. The apparatus preferably includes a drive member that simultaneously rotates both of the hubs to drive the blade relative to the extrusion orifice and cavities. The blade preferably includes an arm that extends into a cavity to place a mold charge into the bottom of the cavity for consistent and accurate placement of the mold charges from one cavity to the next.

  • Patent number: 7335008
    Abstract: An apparatus and a method for producing woodfuel briquettes, pellets, compounds, composites, agglomerates, or granulates as source material for subsequent processing in injection molding or extrusion processes, includes a pressing screw with screw spirals, which rotate around a longitudinal axis and which are arranged inside a screw shell. The feed material is conveyed to the pressing screw via a feed chute located at an input side. At the end of the pressing screw, processing tools are arranged, to which the feed material is conveyed by the rotating screw spirals. In the area of the processing tools, the residual moisture in the feed material evaporates due to the heat generated during the processing procedure, and is vented as a steam flow from the apparatus through the screw shell.
