It is an object of the present invention to provide a method for making it possible to produce, only with mechanical treatment, high-quality rice flour having a rounded particle shape, which is equivalent to fine flour obtained by using enzymes, has characteristics close to the characteristics of wheat flour, and is suitable for production of bread, cakes, noodles, and the like. In order to attain the object, the present invention provides a method for producing rice flour characterized by including primary crushing material rice subjected to soaking and adjustment of moisture content with a disintegrating and sizing device, fine grinding the primary crushed rice with an air mill, and then drying the fine ground rice with an air flow dryer.
摘要:
A vibro-fluidizing device for powder particles which, without using a medium, such as air, gas or other fluid, or impact balls, enables a circulation behavior of powder particles ascribed to vibro-fluidization to appear all over the surface at high speed while almost all power particles (3) are uniformly dispersed by circulating currents, the device having a mechanical arrangement which is designed not to become complicated and yet capable of performing at high speed composite processing, such as disintegration of agglomerate, and dispersion, mixing and drying of powder particles, directly on circulating powder particles. Processing means for powder particles (3) is constructed by using different vibrating bodies (2, 4) in a pair cooperating with a vibrating means (1) to fluidize powder particles (3) by cooperative vibrating action produced between the different vibrating bodies.
摘要:
In a device for treating powder particles by rotary flow, the outer peripheral side of a cylindrical treating chamber (2) into which powder particles are charged is formed with a gas circulation passageway through a circumferential surface plate (202), and the circumferential surface plate (202, 212) is rotatable around the axis of the treating chamber (2). A gas is admitted from the outer peripheral side of the treating chamber (2) through the circumferential surface plate (202, 212) to apply a centripetal force to the powder particles, while the rotation of the circumferential surface plate (202, 212) applies a centrifugal force to the powder particles, thereby forming a fluidized bed that controls the behavior of the powder particles. In another mode, a bag filter (5), which is installed in the axis region of the treating chamber (2), is constructed such that the dispositional proportion in the treating chamber is greater than the planar region width of the gas ventilation means (212) or greater than the area of the gas ventilation means (212). In the axis region of the treating chamber (2) where the centrifugal force is low and the discharge speed is high, the discharge speed of the gas flowing into the treating chamber (2) is reduced for efficient discharge while balancing the centripetal force and centrifugal force, which act on the powder particles, with each other; thus, the operation is controlled by optimizing the inflow and outflow of gas in the fluidized bed behavior.

A powder particle disintegrating and sizing apparatus having a sufficiently wide powder disintegration and sizing range, capable of being downsized, and having high processing capacity. A powder particle disintegrating and sizing apparatus has, in a casing (1a), a horizontally provided drive shaft (2), circular plates (10) fixedly supported with intervals at the drive shaft (2), and stators (5) arranged so as to be opposed to plate surfaces (10a) at lower peripheral edges of the circular plates (10) and each having inclined surfaces (5b) that cause a gap between adjacent plate surfaces (10a) to be narrowed toward peripheral edges of plate surfaces (10a). The plate surfaces (10a) and the inclined surfaces (5b) form gaps (A) where powder stays, and powder particle disintegrating and sizing portions (B) are formed by the peripheral edges of the circular plates (10) and narrawest-gapped portions between the peripheral edges of the circular plates (10) and the inclined surfaces of the stators (5).
摘要:
The present invention relates to a rotating fluidized bed apparatus for powder particle. A gas circulation path is formed at the periphery of the treatment chamber 2 via the circumferential faceplate 202, 212, and the circumferential faceplate is adapted to rotate around an axis. Behavior of powder particles can be controlled by introducing gas from the periphery of the treatment chamber via the circumferential plate 212 to exert centripetal force on the powder particle, while exerting centrifugal force on the powder particles accompanying rotation of the circumferential plate 212. In another aspect, by making the arrangement proportion of the bag filter 5 inside the treatment chamber 2 wider than the surface width of the dispersion plate 212 or larger than the surface area of the dispersion plate 212, it is possible to cause gas that has flowed into the treatment chamber 2 to be discharged at a lower rate at an axial region inside the treatment chamber 2 where centrifugal force is weak and discharge rate is fast. It is possible to carry out optimal operation control of introduction and discharge of gas for fluidized bed behavior.
