A granular material sorting apparatus comprises a transfer device (3) for causing material grains (G) to fall down, optical detector units (2a, 2b) mounted along a locus of falling-down of the material grains (G), an injection nozzle device (4) for injecting air to the material grains, and a control unit (5) for controlling operation of the injection nozzle device in response to detection by the optical detector unit. The optical detector units (2a, 2b) and the control unit (5) optically detect and discriminate colored grains different in color from good material grains and foreign matters in similar color to the good material grains or transparent, which are mixed in the material grains, and activate the injection nozzle device (4) in a predetermined period of time after the detection to remove the detected bad grains. The control unit (5) sets different injection times (F1, F2, F3) and different injection delay times (T1, T2, T3) depending whether the bad grains are colored grains or foreign matters.

A cereal separation apparatus includes a frame, size grading mechanism (4) mounted at an upper portion of the frame for grading particles according to a size of the particles, oscillation-type specific gravity grading mechanism (6) mounted at a lower portion of the frame, air flow-producing mechanism (26,27) for producing an air flow for effecting the specific gravity grading; and a feed passage for feeding the particles, selected by the size grading mechanism, from the size grading mechanism to the specific gravity grading mechanism. The size grading mechanism comprises a perforated, hollow cylinder (4) for grading the particles according to the particle size, and the cylinder is supported on the frame for rotation about an axis of the cylinder. The specific gravity grading mechanism (6) is supported on the frame through oscillation support portions. The apparatus further comprises rotation drive mechanism for rotating the rotary grading, hollow cylinder, and oscillation drive mechanism for oscillating the specific gravity grading mechanism. The apparatus is enhanced in durability, and is capable of effecting the good grading of raw material grains regardless of the nature and conditions of the raw material grains.

A method for measuring ash content of food stuff is carried out by 1) preparing, with respect to food stuff samples whose ash content values are known, a calibration curve by a non-linear analysis of absorbance values and the known ash content of each sample, the absorbance values being obtained by irradiating light having particular wavelengths containing at least an ultraviolet ray band wavelength, the particular wavelength being specific to organic ingredients well coupled to inorganic ingredients which result in the ash content, and 2) deriving, with respect to a sample whose ash content value is unknown, an ash content value of the sample from absorbance values obtained by irradiating, on the sample, light having the particular wavelengths containing at least the ultraviolet ray band wavelength and from the calibration curve prepared in advance by the non-linear analysis. An apparatus for carrying out the method includes a light source section (81), a photo detecting section (88), a storing section (76) for storing the calibration curve, and a calculation section (77) for calculating, with respect to a sample whose ash content value is unknown, the ash content value based on the absorbance values and the calibration curve stored in the storing section. It is possible to speed up the measuring operation and to improve the measuring precision.

In a husking apparatus comprising: a husking portion (26) having a pair of husking rolls (2,3) which are adjustable in clearance between them and rotated in opposite directions with different peripheral speeds to perform husking of paddy grain; and a supply portion (27) disposed above the husking portion for supplying paddy grain to be husked to the husking portion, wherein the supply portion is so constructed as to supply paddy grain from the supply portion to the husking portion in the form of a layer in such a manner that a thickness of the layer of a flow of paddy grain becomes not greater than two grains at the husking portion, and the supply portion is so constructed as to supply paddy grain to the husking portion at a speed not less than a flowing-down speed corresponding to a minimum husking throughput desired of the husking apparatus so that husking is performed with a throughput not less than the minimum husking throughput, it is possible to enhance the husking throughput while minimizing the breakage of paddy grain. In cases where paddy is the one of long-grain variety of rice, the flowing-down speed of paddy grain is set to be not less than 3 m/sec when the paddy grain reaches a region around the clearance between the pair of husking rolls.

In an abrasive type vertical grain milling machine, there are mounted, on a main shaft extending generally vertically and disposed rotatably in an upright bran-removing cylinder, a screw roll for feeding grain, a plurality of abrasive milling rolls disposed below the screw roll in spaced relation to each other along the main shaft for abrading the grain, and a rotary roll disposed below the plurality of abrasive milling rolls for sending out the grain having been abraded to a grain discharge portion in such a manner that the plurality of abrasive milling rolls and the rotary roll are located within the bran-removing cylinder, a gap defined between the abrasive milling rolls adjacent to each other forming a jet-air slot, the bran-removing cylinder being communicated with a grain supply portion at an upper end thereof and with the grain discharge portion at a lower end thereof. A lower part of the bran-removing cylinder is extended downward so as to face horizontally to the rotary roll. Further, the abrasive type grain milling machine has an agitating projection provided on an outer peripheral surface of the rotary roll for agitating the grain having been abraded, and the rotary roll has a jet-air hole through which jet air is sent toward the grain being agitated by the agitating projection.

The apparatus further includes a conveying means(38), steeping tanks(27) and a water re-circulating means(30). A dryer(32) including a rotating barrel adapted for agitation of the food products during cooking is present.
摘要:
A grain sorting apparatus comprises a conveyor belt mechanism for conveying grains, fed by a feed mechanism onto a conveying surface separately from each other at an upstream region with respect to a conveying direction, to a downstream end so that the grains are discriminated and sorted by a discriminating mechanism and a sorting mechanism when dropping from the downstream end along a predetermined path, the belt mechanism being disposed so that the conveying surface thereof declines as going downstream with respect to the conveying direction to prevent the grains being carried by the belt mechanism from rolling toward the upstream direction on the conveying surface of the belt mechanism. It is therefore possible to prevent the grains from rolling on the conveying surface of the conveyor belt mechanism toward the upstream direction relative to the conveying surface of the conveyor belt even when a conveying velocity of the conveyor belt mechanism is high.
摘要:
On a stator core (3), there are wound primary generating windings (W U ,W V ,W W ) of four (4) poles with a distributed full-pitch winding structure and stator excitation windings (W e ) with a concentrated full-pitch winding structure, having the number of poles odd-number times the number of poles of the primary generating windings, that is, twelve (12) poles. The primary windings appropriately produce spatial higher harmonic components of the armature reaction magnetic fields. The excitation windings are connected to the center taps (u,v,w) of the primary windings through a control rectifier (5). On a rotor core (7), six field windings (W f1 - W f6 ) of four poles. The field windings are arranged at positions where they are magnetically coupled with both static magnetic fields produced by the stator excitation windings and odd-order spatial higher harmonic components of armature reaction magnetic fields produced by the currents (I₁,I₂,I₃) in the primary generating windings. The field windings are short-circuited by the diodes (D₁,D₂,D₃,D₄,D₅,D₆), respectively. In the brushless self-excited synchronous generator, the number of slots in each of the rotor and stator can be determined irrespective of the order number of the spatial higher harmonic components of the armature reaction magnetic fields. The generator is simple and rigid in its structure.
