Description

  The present invention relates to an automatic rice mill that operates in accordance with inserted coins to process rice grains such as brown rice into white rice.

  There is known a coin-milling apparatus that operates in accordance with inserted coins and processes the inserted rice grains (brown rice) into white rice (see, for example, Patent Document 1 below).

  In such a conventional automatic rice milling apparatus, a rice milling machine equipped with a milling roll is arranged inside the machine body. Further, a tension hopper into which rice grains are charged is provided on the front wall of the machine body, and the tension hopper is connected to a rice mill through a conveying device such as an elevator. Furthermore, a coin insertion part is provided on the front wall of the aircraft, and coins can be inserted.

  In this automatic rice milling apparatus, rice grains are put into a tension hopper, a predetermined number of coins are put into a coin insertion section, and then the operation switch is operated, and the inserted rice grains are conveyed by an elevator etc. and supplied to a rice milling machine. Furthermore, the milling roll of the rice mill is rotated to process the milled rice, and is taken out as white rice. The automatic rice milling apparatus is operated in a time corresponding to the amount of coins inserted.

  As described above, the conventional automatic rice milling apparatus can automatically process rice milling into white rice according to the inserted coins.

  By the way, in such an automatic rice milling apparatus that can be operated using coins, the rice grains that have been thrown in can be polished and removed as white rice, and the processed white rice is then washed with water (sharpened) and cooked. In recent years, users of the apparatus have a need to obtain white rice that can be cooked by simply washing (sharpening) lightly with water, so-called “simple unwashed rice”.

  On the other hand, white rice that has been treated with rice may be mixed (mixed) with brown or black rice, for example, due to weather or insect damage. There is a need to remove unnecessary white rice (so-called defective products) without need (to remove defective white rice and obtain only white rice as good products).

In this case, it is difficult to determine whether the white rice is a good product or a defective product having a discoloration or the like after the milling process (it is difficult to determine in the state of brown rice or rice bran). For this reason, it is difficult for the user of the apparatus to discriminate (select) and remove defective rice cake and brown rice that are defective when the rice is white rice (in the state of brown rice and rice cake). Measures were anxious.

  Further, the white rice H obtained by milling the brown rice G is further polished to make a simple no-wash rice KM. Further, this simple no-wash rice KM (in other words, a defect that the user of the apparatus has thrown into the tension hopper 14) The simple, unwashed rice KM (one that has turned brown or black due to weather or insect damage) is removed from the brown rice G, which also contains raw rice), and only the simple, unwashed rice KM as a good product is bagged. 27 and can be provided to the user of the apparatus.

  Further, the white rice S which has not been subjected to the rice polishing treatment is subjected to the rice polishing treatment to obtain a simple washing-free rice KM, and further this simple washing-free rice KM (in other words, a defective one which the user of the apparatus has put into the tension hopper 14). Defective rice-free rice KM can be removed from the white rice S containing rice, and only the simple rice-free rice as a good product can be accumulated in the bag 27 and provided to the user of the apparatus.

  Further, from the unpolished white rice (including the case of simple unwashed rice) S (white rice S including the defective one that the user of the apparatus has put into the tension hopper 14), the defective simple unwashed rice KM It is possible to remove only those that have been changed to brown or black due to weather or insect damage, and to collect only clean, clean rice KM as a good product in the bag 27 and provide it to the user of the apparatus.

  As explained above, in this automatic rice milling apparatus 10, this rice grain can be processed regardless of the kind of rice grain put into the tension hopper 14, and the needs of the user of the apparatus can be appropriately handled.

  In the present embodiment, the supply direction of the rice grains by the switching valve 17 is four directions (the destination of the rice grains is any one of the hulling machine 18, the stone removing machine 20, the rice polishing machine 38, and the color sorter 44). However, the present invention is not limited to this.

  For example, the transfer destination of the rice grains by the switching valve 17 may be switched to the stone drilling machine 20 or the sand polishing machine 38, or may be switched to the stone punching machine 20 or the color sorter 44 (that is, in the rice grain transfer destination). The color sorter 44 or the rice polishing machine 38 may be omitted. In this case, an unnecessary button (color selection course selection button 62D or white rice course selection button 62C) among the buttons constituting the processing course selection button 62 can be simplified.

  Furthermore, it is good also as a simple structure which abbreviate | omitted the rice huller 18 from the transfer destination of the rice grain by the switching valve 17. FIG. In this case as well, a simple configuration in which unnecessary buttons (籾 course selection button 62A) among the buttons constituting the processing course selection button 62 can be omitted.

  Moreover, in this Embodiment, although it was set as the structure by which the stone remover 20 is arrange | positioned between the rice huller 18 and the rice milling machine 22, it is good also as a structure which abbreviate | omitted the stone remover 20. In this case, when the switching valve 17 is made to correspond to the rice milling machine 22 and the brown rice course selection button 62B is operated, the rice grains (brown rice G) are directly conveyed from the elevator 16 to the rice milling machine 22 by the switching valve 17. What is necessary is just composition.
