摘要:
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. The pressure and temperature of the melted resin in the first region are controlled in accordance with the properties of the melted resin.
摘要:
A method of producing parboiled rice that does not require waste water treatment equipment and that enriches the amount of γ-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.
摘要:
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.
摘要:
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.
