Description

The present invention relates to a seed grain sorting device that sorts seed meals suitable for raising seedlings from dried and stored raw material seeds.

Conventionally, as a seed grain sorting device such as a seed center, a wind sorter that removes light impurities from dried and stored raw rice cake, and degranulated grains and rice cakes, edible bellflowers from which the rice husks have been peeled off Grain sorter consisting of indent (claw hole) cylinders arranged in multiple stages above and below to remove sprinkled grains, waste grain layer consisting of immature soot, disposed in the next process of the grain sorter, And a specific gravity sorter that performs specific gravity sorting into three regions: a mixed grain layer in which seed meal is mixed at a ratio of about 1: 9 and a refined layer composed of high-quality fine grains with a high specific gravity. (For example, see paragraph [0005] of Patent Document 1). In other words, this kind of seed grain sorting device removes degranulated grains and waste grains that are difficult to germinate when seeding and raising seedlings from the raw material koji, and re-sorts the koji and branched grains with de-wetting process, thereby yielding. It is intended to contribute to the improvement, and to provide only good buds with good germination rate as seed pods. And the degranulated grains and waste grains removed from the raw material koji are used as edible and food processing raw materials after being subjected to the rice hulling and polishing process.

However, the conventional seed grain sorting apparatus is configured to remove the deflated grains, cocoons, and branched grains in the grain sorter composed of an indent cylinder. Since the degranulated grains that have not been supplied are again supplied to the specific gravity sorter in the next step for sorting, there is a problem that the sorting accuracy is very poor such that the degranulated grains are sorted by two sorters. In addition, in the grain sorter consisting of indent cylinders, a large grain sorter with large processing capacity is used in which indent cylinders are arranged in multiple stages in order to remove degranulated grains, wrinkles, and grain with branches. There is a problem that it takes a lot of labor and time for maintenance such as cleaning required for this.

In addition to contacting the refined cereal machine (54) for supplying to the disinfection / drying device (55), the waste particle discharge basket (44) of the specific gravity sorter (31) is supplied with immature rice cake in the waste particle layer area. While communicating with the air conveyor (49) for supply to the rice hull preparation device (18), the mixed grain discharge basket (45) of the specific gravity sorter (31) is a mixed grain consisting of immature straw and seed meal. To the cereal machine for return (51) for re-sorting the cereals by the specific gravity sorter (31), and the defluxing discharge basket (47) of the specific gravity sorter (31) Contacting the grain sorting machine (59) comprising a perforated sorting net cylinder for sorting the mixed grains composed of degranulated grains into fine grains and degranulated grains by means of a mesh, of the grain sorting machine (59) comprising the perforated sorting net cylinder In the refined product outlet, A flow path (62) communicating with the refined cerealing machine (54) is provided to supply the selected excellent rice bran to the seed disinfection / drying device (55), and the pulverized grain receiver of the grain sorting machine (59) is provided. The culvert (61) was provided with a technical means for providing a flow path (63) that communicates with the air conveyor (49) to supply the selected degranulated particles to the pallet preparation device (18). .

Further, according to the invention described in claim 2, the technical means is adopted in which the grain sorter (23) constituted by an indent cylinder is an indent cylinder having a two-stage configuration.

When the dried and stored raw material koji is supplied to the wind separator (4), light impurities such as koji are removed and coarsely selected, and then supplied to the grain sorter ( 23 ) consisting of an indent cylinder. Then, only the grains with cocoons and branches are selected and removed to form mixed grains composed of cocoons and deflated grains. Then, when the mixed grains composed of the pods and defracted grains are supplied to the sorting board of the specific gravity sorter (31), from the lower side to the upper side, the grain layer consisting of immature pods, immature pods and seeds Segregation is performed by segregation into four regions: a mixed grain layer in which cocoons are mixed, a refined layer composed of excellent cocoons having a high specific gravity, and a defatted particle layer in which excellent cocoons and degranulated grains are mixed. At this time, the pulverized particle discharger (47) of the specific gravity separator (31) is in communication with the particle sieving machine (59) composed of a perforated screening mesh cylinder, and the pulverized particles and deflated particles of the deflated particle layer are communicated. Is separated and sorted into excellent rice cakes and crushed grains. Then, the separated and sorted excellent rice cake is taken out from the flow path (62) connected to the refined grain mill (54) to be supplied to the seed disinfection / drying device (55). On the other hand, the fine grain discharger (46) of the specific gravity sorter (31) is in communication with a fine grain cerealing machine (54) for supplying the fine grain to the seed disinfection / drying device (55). Is directly supplied to the seed disinfection / drying device (55) by the refined grain mill (54). As a result, the grain sorting machine (59) made of a perforated sorting screen can adopt a small processing capacity, and the grain sorting machine (23) made of an indented cylinder does not remove the degranulated grains. Therefore, it is possible to employ a filter with high sorting accuracy and low processing capability. In addition, the entire configuration of the seed grain sorting apparatus can be reduced.

And since the grain sorter (23) composed of indented cylinders has a two-stage configuration, it only needs to have a function of sorting and removing only the grains with culm and branch rachis, and adopts one with a small processing capacity. Thus, labor and time required for maintenance such as cleaning can be greatly reduced.

The inventors of the present invention have a problem in terms of ability and accuracy of a grain sorter composed of indented cylinders. Then, if it is set as the structure which sorts the degranulated particles mixed in a granule in a specific gravity sorter, on the sorting board of this specific gravity sorter, 4 of a waste grain layer, a mixed grain layer, a refined layer, and a defatted grain layer It was found that segregated in one region (as shown by the crosses in FIG. 2, the degranulated particles are distributed on the rocking side). Furthermore, if this defatted particle layer is passed through a particle sorting machine comprising a porous sorting mesh cylinder, it is possible to sort and remove the degranulated particles with high accuracy, and eventually a grain sorting machine comprising an indent cylinder in the previous process. It was thought that downsizing of the overall configuration could be realized.
