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.

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.

A pretreatment process in a flour milling method in which raw wheat grains are first polished and the polished grains are ground and milled for producing end flour, includes a first, a second, a third polishing step, and a step of adding water. In the first polishing step a pericarp of each wheat grain is removed, in the second polishing step a seed coat of each raw wheat grain is removed, and in the third polishing step a part of cell walls of aleuron layer cells that was in contact with the removed seed coat is removed so that a cell membrane of the aleuron layer cell is caused to be ruptured and that a substance in the aleuron layer cell is caused to be in a state which permits the substance to flow out. In step of adding water, by adding the water to each raw wheat grain, the substance in the aleuron layer cells is caused to flow out from the aleuron layer cells, resulting in producing a polished grain in a state in which the substance in the aleuron layer cell has been separated from each raw wheat grain. It is possible to increase the yield of the end flour collected by the subsequent grinding operation.

Raw wheat grains are polished after being subjected to a first water addition and being tempered, and the polished wheat grains are ground after being subjected to a second water addition and being tempered. The first water addition is to cause the raw wheat grains to have a water content of 12-14%. The tempering of the raw wheat grains is performed for 16-36 hours so that the water sufficiently penetrate into the inside of the raw wheat grains. The method of flouring includes the steps of measuring a water content of the flour obtained by the grinding of the grains, comparing the amount of the measured water content with a predetermined target water content of the flour, and adjusting the amount of water to be added during the second water addition if there is a difference between the measured water content and the predetermined target water content. Thus, it is possible to reduce the time required for the tempering of the polished wheat grains and to adjust the second water addition based on the water content in the flour.

A method of and an apparatus for manufacturing no-bran cereal such as no-bran rice which require no washing before cooking. With the method and 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.

The circulating type grain drying machine is provided in which, at the grain filling operation, a controller causes a first heated air generator to operate and a second heated air generator to stop operating, and also causes, according to the detected values of the outside air humidity from an outside air humidity detector, an airflow control section to operate so as to change the quantity of the airflow by an air exhaust section. Also, at the drying operation, the controller controls the first heated air generator and controls the temperature of the heated air supplied into each heating pipe according to the detected values of the grain water content value, and controls the second heated air generator and controls the temperature of the temperature of the heated air supplied into the drying section according to the detected values of the grain water content values and the grain filling amount.

A water adding control apparatus includes a microwave detecting unit which enables the detection of microwave value proportional to the water content amount of the water added grain and which makes it unnecessary to make calculations for an estimated water content value of the water added grains. The water adding process is started by inputting initial water adding amount, the microwave value of the raw grain after the addition of water is measured, the measured microwave value is set as the target microwave value which serves as control reference, and the water adding amount is feed-back controlled for the actually measured microwave value to constantly match the target microwave value.

A husking apparatus for cereals comprises a pair of rolls provided parallel to each other with a clearance therebetween, and an inclined guide chute situated above the rolls. The guide chute slides down cereal grains between the rolls, and the rolls rotate in opposite directions, respectively, to nip and shell the cereal grains therebetween. The guide chute and the rolls are located so that a guide surface of the guide chute is substantially perpendicular to a line connecting the centers of rotational shafts, and that an extension line from the guide surface passes within a range of .+-.10 mm on both sides of a middle point of the clearance between the first and second rolls. The guide surface of the guide chute has such an inclination that the cereal grains spread all over a width of the guide surface in the substantially single layer of a band-like shape and are accelerated up to a speed less than peripheral speeds of the rolls while they slide down along the guide surface. The cereal grains are thus uniformly fed between the rolls in regular postures and have less irregular reflection due to collision with the rolls, and it is possible to perform reliable husking which causes less broken grains.

The color sorting apparatus includes a grain guide device, a grain feeder, an illumination device for illuminating the grain, an optical detector consisting of an optical detection section for receiving the light from the illuminated grain and a background, and ejector for rejecting the grain. The illumination device employs at least one light source having spectral energy distribution in both the visible light region and the near infrared region. At least one set of the optical detection device for monitoring a predetermined detection field is provided. The optical detection section of the optical detection device includes a first light receiving sensor having high sensitivity to the visible light region and a second light receiving sensor having high sensitivity to the near infrared region. The single color sorting apparatus is capable of sorting and rejecting not only foreign materials with color different from that of the acceptable products in the visible light region but also foreign materials with the same color as the acceptable product or transparency in the near infrared region.
