And can be shipped. Reference numeral 83 denotes a foreign substance tank for storing foreign substances sorted and removed in the rough sorting step V.

The process from receipt of the soybean preparation line C for natto to shipment will be described.
The soybeans for natto introduced into the raw material input hopper 1 at the consignment site are once stored in the raw material storage tank 50 for each product type, for example.

  The soybeans to be shipped are discharged from the raw material storage tank 50 and conveyed to the coarse sorting step V by the conveyor 51 and the coarse selection elevator 53. First, it is supplied to the wind power sorter 54 and is subjected to wind sorting so that lighter stems, sheaths, hides and damaged grains are sorted and removed as compared with the sized particles. Next, it is supplied to the coarse sorter 55 to sort and remove long objects such as sawdust, stones are removed by the stone remover 56, and worm-eaten beans and immature beans having different sizing and specific gravity are sorted and removed by the specific gravity sorter 57. Is done. The soybeans that have passed through the above-mentioned various devices and passed through the coarse sorting step V are sequentially separated through the first grain sorter 60a and the second grain sorter 60b and separated into regular, small, and extremely small grains. The product is stored in a tank 69 for product shipment.

  The soybeans stored in the product shipping tank 69 are conveyed to the roll sorter 61 by the conveyor 63 and the shipping elevator 64, and the flattened and broken soybeans are separated and removed. The soybeans that need to be polished are supplied from the selection passage 66 to the polishing machine 65 to polish the soybean surface, and then supplied to the color sorter 62 to remove the colored grains. The soybeans that have passed through the color sorter 62 are packaged and shipped through the shipping measuring tank 67 and the bag measuring tank 68 in the shipping process U, but are supplied to the metal removing process M as needed to supply the metal. You may make it ship, after removing the metal mixed with soybeans through the removal apparatus 70.

The effect by the structure of the soybean preparation line C for natto of this Embodiment is described below.
By arranging the polishing machine 65 in the process immediately before the color sorter 62, the color sorter 62 can sort immediately after polishing the surface of the soybean, so that the system for discriminating the color of soybean is improved, Since the soil on the surface of the soybean is removed, the number of soybeans that are sorted and removed by misclassifying the original good soybean as a defective product can be reduced, and the yield of soybean can be increased.

  Moreover, since the polishing machine 65 is configured to be supplied from the selection passage, it is not necessary to pass all the soybeans through the polishing machine 65. Therefore, soybeans that do not need to pass through the polishing machine 65 are quickly supplied to the shipping process U. In addition, since the processing capability of the polishing machine 65 can be made relatively small, a small polishing machine (or a small number of polishing machines) may be used, so that a compact facility can be obtained.

  In this embodiment, the flow rate adjusting tanks 13 and 53 are provided before the rough sorting steps R and V, but before the fine sorting step W, that is, before the grain sorter 60 and the roll sorter 61. By arranging the flow control tanks 90, 91, 92 in front of the polishing machine 65, it becomes possible to sequentially supply soybeans in accordance with the processing capacity, and various parts of the coarse sorting processes R, V accordingly. In addition, since the processing capability of various devices in the selection process W can be made relatively small, a compact facility can be obtained.

  Although not shown in FIG. 1, the color sorter 62 is supplied from the color sorter selection passage 78 in the same manner as the polishing machine 65 as shown in FIG. Since the discharged soybean can be directly supplied from the roll sorter 61 to the shipping process U, soy that does not need to pass through the polishing machine 65 and the color sorter 62 can be quickly supplied to the shipping process U. In addition, by providing a transport device 79 for supplying soybeans from the product tank 69 to the shipping process S for tofu, it becomes possible to use soybeans for natto when there is a shortage of soybeans for tofu, It becomes possible to respond quickly and flexibly to customer responses.

  When processing soybeans like tofu, it is not necessary to consider the particle size and shape of soybeans, so only the coarse selection process is performed, and multiple varieties can be mixed. There is no problem. Moreover, when processing soybeans like natto, it is necessary to go through a selection process in addition to the rough selection process for foods that need to have a uniform particle size and shape. In the present embodiment, tofu was given as an example of food to be shipped after only coarse selection, and natto was given as an example of food to be shipped after rough selection and selection. There may be boiled beans.
