Abstract: A pulse color sorter which permits removal of internally and externally moldy pulse having afuratoxine as decomposition product is disclosed. The pulse color sorter comprises a first detector which provides a first and a second detection signal according to dispersed and transmitted light having two different wavelengths (for instance 700 and 1,100 nm) with different contents of information due to the separation of wavelengths, a second detector which provides a third detection signal according to reflected light, and a controller which calculates division of the first and second detection signals from the first detector, compares the resultant value calculated to a first predetermined threshold value while also compares the third signal from the second detector to a second threshold value, and outputs an eject signal if either of the compared signals is beyond the corresponding threshold value. According to the eject signal, corresponding defective pulse is forcibly ejected.

Abstract: A vertical milling machine comprises a first milling part and a second milling part situated under the first milling part, the first and second milling parts having a common main shaft extending vertically. The first milling part has a supply part of grain on an upper end side thereof and a discharge pare of grain having been milled in the first milling part on a lower end side thereof. The second milling part has a supply part of grain to be milled in the second milling part on a lower end side thereof and a discharge part of grain having been milled in the second milling part on an upper end side thereof. The grain discharge part of the first milling part is communicated with the grain supply part of the second milling part through a grain transfer passage extending therebetween.

Abstract: An abrasive type vertical grain milling machine comprises a perforated cylindrical body which serves to define an outer periphery of a grain milling chamber and which has a plurality of vertically arranged resistance members projected radially into the grain milling chamber so as to impart resistances to motions of the grains in a circumferential direction of an abrasive type roll assembly, an amount of projections of each of the resistance members being made to be adjustable, and further has projection amount adjusting mechanisms for adjusting independently the respective amounts of projection in the radial direction of the plural resistance members located in different vertical positions, and therefore, it is possible to adjust independently the resistance imparted to the motions of the grains within the grain milling chamber in each of the upstream-side region and downstream-side region of the grain milling chamber.

Abstract: An abrasive type vertical grain milling machine in which each of spacers comprises a boss portion fitted on a main shaft and a plurality of arm portions extending from the boss portion in the radially outwardly and serving to induce bran removing air into a grain milling chamber through spaces between the circumferentially adjacent arm portions, is capable of discharging bran produced in the grain milling chamber with high bran discharging power and has little possibility that the bran removing power is reduced during operation.

Abstract: An abrasive type vertical grain milling machine comprises a perforated cylindrical body having at least one perforated arcuate plate member which is formed therein with both a first group of elongated bran-removing holes serving to lead grain to be milled in a direction from an inlet side toward an outlet side of a grain milling chamber when the grain is rotated in the direction of rotation of a grain milling roll assembly within the grain milling chamber and a second group of elongated bran-removing holes serving to lead the grain to be milled in a direction from the outlet side toward the inlet side of the grain milling chamber when the grain is rotated in the direction of rotation of the grain milling roll assembly within the grain milling chamber, and therefore, grain can be milled highly efficiently and the progress of breakage of grains caused at the time of grain milling can be suppressed.

Abstract: A pearling machine has an abrasive type pearling roll assembly which is formed by stacking a plurality of pearling rolls via intervening air blowing spacers. Stirring bars are secured to the outer periphery of the individual pearling rolls. Resistance bars are provided on the inner surface of a vertical polygonal bran removal cylinder. With a cooperative function of the stirring and resistance bars, grains supplied to a pearling chamber defined by the pearling roll assembly and the bran removal cylinder receive active spinning and revolution action. The grains thus receive uniform cutting action, and thus they are pearled uniformly. The vertical pearling machine permits optimum pearling of grains in dependence on the kind and character of the grains and is suited particularly to the pearling of tempered wheat with outer layer part having been made tough and inner layer part having been made soft.

Abstract: A vertical type grain-milling machine has a perforated bran removing cylinder arranged vertically with respect to a machine frame; a main shaft which is rotatably provided within the perforated bran removing cylinder; and a milling roll and a screw roll which are in abutment with each other and which are mounted on the main shaft, the milling roll being associated with a grain discharging section and the screw roll being associated with a grain supplying section. The perforated bran removing cylinder is surrounded by an air in-take frame which has a large number of through-holes for causing in-flowing air to have a downward component of orientation. The discharging of the bran externally of the machine is enhanced and the adherence of bran onto the inner wall of the air in-take frame and the perforated bran removing cylinder is prevented.

Abstract: An induction synchronous motor includes a unitary rotor having first and second pole type rotor cores, first and second stators, a voltage phase shifting means, and DC magnetic excitation circuits. Both of the rotor cores are mounted on a common rotor axis with a predetermined space between them. The first and second rotor windings are wound on the first and second rotor cores, respectively. A plurality of diodes is each connected in parallel between series-connection nodes of the first and second rotor windings. A plurality of rotor conductors is provided on the peripheries of and extend through the first and second rotor cores. A pair of short-circuit rings short-circuits both ends of the plurality of rotor conductors. The first and second stators surround the first and second salient pole type rotor cores, respectively, and have the same number of poles as the first and second rotor cores. The voltage phase shifting means selectively produces a phase difference of 0.degree.

Abstract: A synchronous motor includes a unitary rotor, a first stator, a second stator and phase-changing switches. The unitary rotor has a first rotor portion formed by a first permanent magnet and a second rotor portion formed by a second permanent magnet and an induction type rotor and these first and second rotor portions are mounted on a common rotary axle with a predetermined space provided therebetween. The first stator faces the first rotor portion for producing a first rotating magnetic field. The second stator faces the second rotor portion for producing a second rotating magnetic field and is disposed such that, at the starting operation, the attracting action or the repelling action produced between the first rotating magnetic field and the first permanent magnet is canceled by the repelling action or the attracting action produced between the second rotating magnetic field and the permanent magnetic field.

Abstract: A flour milling method and system therefor comprising the steps of separating foreign materials from raw wheat, humidifying the raw wheat, polishing the raw wheat, and conditioning the polished wheat, further comprises a step of cleaning the polished wheat at a subsequent step of the polishing the raw wheat. The flour milling method and system therefor may further comprises a step of stirring the cleaned polished wheat at a subsequent step of the cleaning step of the polished wheat. The bran powder which has been entered into the creases of the polished wheat at the polishing step, absorbs cleaning water and then flows out from the creases with the cleaning water. Since the bran powders in the creases of the polished wheat can be removed effectively, the milling efficiency is improved.
