Abstract: A method of producing parboiled rice that does not require waste water treatment equipment and that enriches the amount of ?-aminobutyric acid contained in the parboiled rice. The method includes partially milling raw material brown rice, wetting the partially milled rice grains by forced-air using moist air or mist, moisture-tempering the wetted rice grains, steam-boiling the water-tempered rice grains at normal pressure to heat the rice grains with steam, steam-boiling the rice grains heated in the normal pressure steam-boiling process using pressurized steam, cooling the rice grains steamed under pressure in the pressurized steam-boiling step to cool at least a surface of the rice grains, finish milling the rice grains cooled in the cooling step, and drying the finish-milled rice grains.

Abstract: A method of and device for removing a liquid from a resin of high melting point by means of a co-rotating twin extruder and an operation system of a liquid removal molding of a resin of high melting point by which a scaled down, highly effective, high performance and continuous stable operation of the device may be achieved.

Abstract: An extrusion method and apparatus for removing volatile contents from solid state resin materials is described. A cascade-type extruding device is used having first and second extruders. A top end portion of the first extruder 10 is directly connected to a rear side portion of a cylinder of the second extruder 100. Volatile contents of a melted resin, which is melted when the solid state resin material is supplied to the first extruder, are removed in a volatile content removing vacuum unit provided on an upstream side of the connection between the first and second extruders. The melted resin is then extruded from a nozzle provided at a top end portion of the second extruder. The volatile content removing vacuum region of the volatile content removing vacuum unit 140 extends over a first region, which is under the control of the first extruder, and a second region, which is under the control of the second extruder.

Abstract: A screw for a molding machine comprises a feed zone, a compression zone and a metering zone. The metering zone 12 is provided with a screw element having an intermediate mixing element 12b and a forward end mixing element 12a, and the upstream side of the intermediate mixing element is composed of a deep flight channel screw, and the downstream side of the intermediate mixing element is composed of a shallow flight channel screw.

Abstract: In a multishaft supporting device comprising a barrel and sleeve adapted to receive a plurality of shafts of a kneader, a twin shaft extruder or the like, inserts made of a metal having larger thermal expansion coefficient than the barrel and sleeve are inserted between the barrel and the sleeve to improve heat transfer therebetween.
