Abstract: A quality evaluation method and apparatus for non-bran rice evaluate quality or taste of non-bran rice by identifying proportions of a hull layer, an aleurone layer, an endosperm layer, which adhere to a surface of the non-bran rice according to luminance levels of self-emitted fluorescence obtained by irradiating the non-bran rice with excitation light.

Abstract: Warm and wet air are applied to brown rice with germinated germs, produced by adding water to the brown rice, for removing water attached to a surface of the rice. A surface of the germinated brown rice is polished by a rice-polishing machine while remaining the germinated germs to obtain rice with germinated germs. Water of about 1 to 10% of rice weight is added to soften the rice surface. The rice and granules whose granule size is set to a constant granule size smaller than that of the rice and which is heated to 60° C. or higher are mixed with the rice and stirred. Rice bran remaining on a rice surface after polishing is absorbed by the granules and is removed. And, the rice and granules are separated from each other.

A first background and a second background of the pellet separator are formed in the vicinity of a parabolic trajectory and shaped to be curved along the parabolic trajectory in the downstream direction thereof.

Abstract: The present invention relates to a method for analyzing residual agricultural chemicals which comprises the steps of acting a reduced glutathione as a reactive substrate and a glutathione transferase serving as a catalyst for the reaction on a carbofuran derivative or a methomyl derivative as a carbamate type agricultural chemical of a new series to thus derivatize the agricultural chemical into a substance having a high choline esterase-inhibitory activity; reacting the substances formed through the derivatization reaction with a choline esterase; and then detecting the presence of the agricultural chemical as the new series of carbamate type one included in a sample to be examined on the basis of the changes in the choline esterase activity thus detected.

Abstract: An apparatus for manufacturing no-bran cereal such as no-bran rice which require no washing before cooking. With the apparatus, bran stuck on a surface of a grain of the polished cereal is easily removed without imparting any damage on the surface, and further moisture in the grain is maintained to increase taste of the cereal. Moisture is added to the polished cereal and granular material is mixed and stirred with the moistened polished cereal to polish a surface of each grain of the polished cereal and remove bran stuck on the surface of the polished cereal. Then, the polished cereal is separated from the granular material to obtain the no-bran rice.

Abstract: The present invention relates to an impact crushing apparatus that mills grain between a milling cylinder and a screen. Each of a plurality of blades mounted along the circumference of the milling cylinder comprises a columnar body with a square cross section, cutting tools disposed on all ridges of the columnar body, and mounting parts formed at the top and bottom of the columnar body. Each blade is attached to the milling cylinder in such a way that any one of the four directions of the blade can be selected by rotating the blade around the central axis of the columnar body.

Abstract: A magnetic metal removing device for color sorting apparatus includes a hollow feeding roll. Within a hollow portion of the feeding roll, a magnet is arranged such that it closely opposes to a part of an inner surface of the hollow feeding roll to form a magnetic force active surface on the corresponding outer surface of the feeding roll. Magnetic metal mixed in raw granular objects is attracted on the magnetic force active surface. The magnetic forced active surface changes to a magnetic force inactive surface as the feeding roll rotates. The magnetic metal caught on the feeding roll is released from the magnetic forced inactive surface and colleted by a collecting device.

Abstract: This invention is made on the basis of the novel findings that when, after pulverization and coating film peeling, pulverized pieces to which the coating film not peeled by the coating film peeling adheres and pulverized pieces having no coating film adhered are separated, a substantial coating film removal ratio effectively increases. In this invention, pulverized pieces obtained upon pulverization of coated resin molded products and coating film peeling of pulverized pieces are prepared. The presence/absence of adhesion of the coating film is sensed and determined for each individual pulverized piece. On the basis of the determination result, a pulverized piece having the coating film adhered is separated from pulverized pieces having no coating film adhered. After the separation, molding is performed by using the pulverized pieces having no coating film adhered.

Abstract: A rotatively oscillating separator comprising separating vessels 4 each having cone-shaped separating plate 5 disposed in the vessel, and drive means 6 for rotatively oscillating said separating vessels 4, mixed rice consisting of unhulled rice and unpolished rice being fed onto the separating plates in the separating vessels at a given location to separate the unhulled rice and the unpolished rice from each other, the unpolished rice being discharged through raised peripheral portions of the vessels, and the unhulled rice being discharged through the central bottoms of the separating vessels.

Abstract: An optical detection device for use in a color sorting apparatus for granular objects includes a CCD linear sensor. The CCD linear sensor comprises a plurality of light receiving elements arranged in one row each of which is capable of detecting red, green and blue wavelengths. The CCD linear sensor receives light from a granular object and a background which are irradiated by a red light source, a green light source and a blue light source. The red, green and blue light sources are switched over while the granular object is passing within an optical detection area. The CCD linear sensor receives light from the granular object in synchronization with the above switching operation of the light sources.

Abstract: A break roll machine wherein a timing belt of a differential transmission mechanism can be removed easily and wherein the removal of a roll pack module from a machine frame and the installation of the new pre-assembled roll pack module can be performed easily in a short time is disclosed. A cutout portion is provided to one of a paired tension arms so that the one tension arm is rotatable around a pivot point at an upper portion of the tension arm. As a rotary shaft of an idler pulley is released from the tension arm through the cutout portion, the timing belt can be removed easily. An air cylinder is rotated freely by a first and a second linkage member. An operator can easily access to a bolt located behind the air cylinder only by inclining the air cylinder at any desired direction.

Abstract: The machine comprises a front door, a roll cover having a main roll cover and a feed roll cover, a first fulcrum axis between the main and feed roll covers, and a second fulcrum axis between the feed roll cover and a frame. The front door has a hinge at the upper portion so that it is kept at a self-supporting state when opened. The main roll cover is foldable on the feed roll cover about the first fulcrum axis. The feed roll cover is swung upwardly about the second fulcrum axis and is finally kept at the self-supporting state with the main roll cover folded on the feed roll cover. Where the front door and the roll cover are kept in their self-supporting states, since a pair of rolls and a stock feeder are fully exposed, the remaining stock accumulated in the machine can be removed easily.

Abstract: A method for determining the concentration of dioxins present in a sample comprises the steps of chemically linking a hapten having a structure mimic to a part of the structures of dioxins with a ruthenium complex to thus form an antigen; incubating the resulting antigen together with an antibody fixed to or immobilized on an electrode to thus induce an antigen-antibody reaction; oxidizing or reducing the ruthenium complex by applying an electric voltage to the reaction product through the electrode to thus induce electrolytic light emission; and observing the electrolytically emitted light rays to quantitatively determine the amount of the antigen and to thus evaluate the concentration of the dioxins present in the sample. The present invention permits the elimination of the use of any reagent such as hydrogen peroxide required for the chemical luminescence, the highly sensitive analysis of dioxins and the miniaturization of the device to be used in the analysis of dioxins.
