Abstract: The method for sorting grain (10) comprises the step of conveying the grain (10) with at least a part of the pericarp, seed-coat or aleuron layer or any combination thereof attached into a colour-sorting device (1). The grain (10) is sorted according to colour into at least a first colour-fraction (11) and at least a second colour-fraction (12). The first colour-fraction (11) or the second colour-fraction (12) is conveyed into a size-sorting device (2). Subsequently, the first colour-fraction (11) or the second colour-fraction (12) conveyed into the size-sorting device (2) is sorted according to size of the grain (10) into a size-accept fraction (13) and a size-reject fraction (14).

Abstract: The invention relates to a rice-polishing machine sieve profile. In one embodiment this is accomplished by an elongate, tubular shaped sieve arrangement with a polygonal profile, comprising a cam essentially cylindrical shape co-axially arranged” within the sieve arrangement such that between an inner surface of the sieve arrangement and a jacket-surface of the cam a polishing chamber has a maximal and a minimal radial distance between jacket-surface of the cam and the inner surface of the sieve arrangement, characterized in that the number of corners of the polygonal profile is larger than 8.

Abstract: An apparatus and method for removing pericarp from a seed, such as a corn kernel. The method includes sonicating the kernel to loosen the pericarp and then separation of the pericarp. One example of separation is by frictional milling. An additional optional aspect of the invention is isolation of the pericarp from the remainder of the seed and/or further cleaning or purification of the pericarp.

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: A device inside a grinder to peel the inner embryo membrane of coffee beans is disclosed. It has a motor with a motor shaft, a positioning cylinder located on the lateral side of a motor and having a lower exit inside a conveyor base, and a conveyor base, which is on the lateral side of the grinder and has an extruded exit end on the other side of the grinder. The motor shaft connects to an eccentric synchronic rotation grinding bar. During rotation, the grinding surface completely hits the inner ring rim of the positioning cylinder and coffee beans are ground into particles. When the particles fall, due to low specific weight, the embryo membrane is drawn by a fan located on the lateral wall of a grinder and is collected in a dust collection bag.

Abstract: The invention relates to a method of removing the fibrous shells from cereal grains. This method according to the invention comprises a pretreatment step, wherein the moisture content of the cereal grains is increased, e.g. in the case of corn grains from 16 to more than 20% by weight, followed by the step of exposure of the pretreated grains to a thermal shock by means of a cryogenic medium and thereafter mechanical treatment step thereof.

Abstract: A bean sprouts processing apparatus includes a feeding section, a treating section and a separating section arranged in sequence substantially in a horizontal manner. The feeding section includes a receptacle for receiving un-processed bean spouts therein and a conveyor for conveying the bean sprouts to the treating section. The treating section has a sprout tray movably supported on a base with a shaking device arranged between the sprout tray and the base to shake the sprout tray relative to the base so as to separate husks from the sprouts and to break roots of the sprouts and also move the sprouts and the separated husks and broken roots toward the separating section. A cooling device is optionally mounted on the base of the treating section to lower the temperature of the sprouts down to about 3.degree.-5.degree. C. The separating section has a sprout support plate movably supported on a base to receive the sprouts from the treating section.

Abstract: A grain separator is disclosed comprising a plurality of operatively connected grain separator units and a grain inlet for feeding grain into the separator, wherein the grain is separated . The grain separator also has an outlet for dispensing the grain after the grain is separated and an internal drive for operating the units in separating grain.

Abstract: A vertical type impact rice huller which is free from the occurrence of collision of the grain is disclosed.

Abstract: A vertically disposed unhulled rice lifter is mounted adjacent a stationary frame with its upper end secured against movement relative to and in communication with a hulling section which is secured on the frame above and to one side of a vibratory separating section of the apparatus. Grain from the lifter is hulled between a pair of hulling rolls in the hulling section and is fed downwardly through an air stream on to a vibrating surface on the vibratory separating section. The air stream conveys away hulls and dust from the hulled rice; and the vibrating surface separates the hulled rice grains from any unhulled rice which may have passed through the hulling section. The unhulled portion of grain is then returned to the lifter and the completely hulled grains are conveyed to a storage section.

Abstract: A driving device of sorting cylinders for use in a rotary type rice hulling and sorting device, characterized by comprising a hulling part, a pneumatical sorting part and a rotary type sorting part provided with sorting cylinders rotatably installed therein with one end thereof as the feeding side of rice grains to be sorted and the other end thereof as the discharging side of rice hulled and sorted and having a large number of recesses formed on the internal surface thereof and receiving troughs for taking out the rice grains scooped up by said recesses, said hulling part, said pneumatical sorting part and said rotary type sorting part being integrally constructed and interlocked, and the rotational speed of said sorting cylinders being controllable optionally in no connection with the revolution of said hulling part and said pneumatical sorting part.

Abstract: Methods and apparatus for processing grain to provide meal, grit, flour and masa products suitable for human consumption and by-products suitable for use as animal feed and industrial products. The methods includes forming a slurry of the grain with water and processing the slurry through dehusking, germ detaching, grinding and sifting stages while maintaining the grain at a relatively high moisture content. Partially different methods are employed depending on whether the processed grain is sorghum, wheat or corn. The processing apparatus includes a dehusking unit having a plurality of pump stages to remove the husks from the grain kernels without cracking a substantial portion of the kernels. A fluidized bed dryer is utilized to remove excess water and to surface dry the kernels and husks. For sorghum grains a centrifugal impact germ detacher is utilized to break up the dehusked kernel and separate the germ and oil from the endosperm.

Abstract: Apparatus comprising hulling means, winnowing means, sorting means, and conveyor means. Said hulling and winnowing means are housed in a platform-like box having longer longitudinal sides and shorter transverse sides. The sorting means is operated to move along the longitudinal sides of box, and the path of circulation of grain through the hulling means, conveyor means and sorting means is made short by locating them adjacently to each other.
