  The input hopper 12 is provided with a grain sensor 12b for detecting the input of the grain and a rice seed sensor 12d as a determining means for determining whether the input grain is straw or brown rice. In the case of brown rice, the hulling machine 14 opens the gap between the hulling rolls 14a and passes through the brown rice without any hulling action. The brown rice tank 16t is provided with a brown rice tank full sensor 16f for detecting overflow and a brown rice tank lower limit sensor 16b for detecting the presence or absence of brown rice, and the control unit operates the equipment as described later according to the detection signals of these sensors. Control. The rice milling machine 16 is configured such that the degree of milling can be controlled by moving and adjusting a compression plate (not shown) provided on the discharge port side according to a control command of the control unit.

  The rice mill 16 is connected to a white rice tank 13 via a discharge controllable discharge path 16a, and a charge tank 16c for storing initial milled rice until the milling pressure in the initial stage of filling the rice mill is increased by the switching valve 16j. The initial milled rice is subjected to the milling process on the whole brown rice by additionally supplying it to the milling machine 16 via the second elevator 16e just before the end of the milling of the whole brown rice.

  The reduction switching valve 14p is a switch for discharging from the first elevator 14e through the reduction passage 14q to the reduction port 14r above the charging hopper 12 when a small amount of grain remains in the charging hopper 12 due to insufficient charge. Part. When the brown rice is exhausted, the remaining rice outlet 15c of the foreign matter sorter 15 is sent from the first elevator 14e to the rice mill 16 by the remaining rice transfer path 14g and the second elevator 16e, and the entire amount is processed.

  As shown in FIG. 2, the specific configuration of the rice bran rice milling facility partitions a machine room 2 and a guest room 3 as an operation space on the front side thereof in a rectangular building 1 by a partition wall 11. In the present embodiment, the cabin 3 side is the front and the machine room 2 side is the back.

  In the machine room 2, a hulling machine 14 is arranged on the side of the loading hopper 12 projecting rearward of the partition wall 11 via the first elevator 14 e, and a pallet or the like is placed below the loading hopper 12 below it. The foreign matter sorter 15 is arranged facing the back side. A second elevator 16e is arranged on the side of the foreign matter sorter 15, and the rice mill 16 is connected to the discharge passage 16a of the rice milling machine 16 together with the rice selection outlet 15b and the remaining rice feed path 14g to circulate and polish the rice. In addition, a straw bag 16b is disposed in the rear part of the machine room 2 via a straw suction part 16f connected from the rice milling machine 16, and the transfer duct 16d is branched to the cabin 3 side.

  On the side of the guest room 3, as shown in the front view on the guest room side of the partition wall in FIG. 3, a charging hopper 12 for pouring rice and a white rice tank 13 for taking out white rice are arranged facing the guest room 3. Is provided with an operation unit (operation panel) 11a for specifying the degree of milling of rice milling and charging a fee. The take-out section provided at the lower part of the white rice tank 13 is constructed by incorporating a drawer-type intermediate tray 13b for handling small bags. On the side thereof, the leading end of the transfer duct 16d is opened to the basket extraction portion 16p facing the passenger cabin 3. The operation panel 11a or the safe box is configured as a maintenance door for maintenance of the loading hopper 12, the first elevator 14e, and the foreign matter sorter 15.

  The operation control of the rice milling equipment having the above-described configuration is performed by the coin processing unit 11b processing coins inserted according to the operation unit 11a shown in the sketch of FIG. The corresponding rice milling process is set by the whiteness button 11d for selecting the desired whiteness from "8", and the rice milling equipment is activated.

  When the rice hull milling machine is activated, when the rice bran is put into the charging hopper 12, the rice huller 14 and the foreign matter sorter 15 perform the rice hulling and foreign matter sorting processing from the first elevator 14e. When brown rice is thrown in, it passes through the rice huller 14 with the rice hull roll 14a opened, and enters the foreign matter sorter 15 by the discrimination of the rice seed sensor 12d. The brown rice is further processed by the rice mill 16 from the second elevator 16e and can be removed from the white rice tank 13.

  The control of the rice milling process waits until a predetermined amount of brown rice is stored in the brown rice tank 16t, and then starts the rice mill 16 and temporarily stores the treated rice from the initial rice mill in the charge tank 16c. At the time when the process is nearing completion, the entire amount of rice is discharged to the white rice tank 13 after circulating rice milling for a predetermined time including the initial milled rice.

(Rice mill start control)
The start-up waiting time of the rice milling machine 16 is defined as the time until the amount of brown rice filled in the milled portion is stored in the brown rice tank 16t, and this waiting time is switched depending on the input rice species. That is, for rice bran or brown rice received in the input hopper 12, rice classification means by the rice type sensor 12d for identifying either type is used, and if the rice type identification result is rice bran, the rice polishing is performed at a later timing than the brown rice. A long standby time is applied to compensate for the weight loss due to hulling so that the machine 16 is activated.

  In this way, the amount of brown rice at the start of rice polishing is increased by delaying the start timing of the rice milling machine 16 from the brown rice input only in the case of rice bran input, so that an appropriate amount of rice milling can be compensated for by the amount of reduction due to rice hulling. . Therefore, it is possible to perform an appropriate rice milling process in accordance with the input of rice bran. Therefore, with such a simple method of adjusting the start timing, both the rice bran and brown rice have a certain accuracy without complicating the apparatus configuration and increasing the cost. The whitening process can be secured.

  Further, when the brown rice tank 16t uses the lower limit sensor 16b for detecting the presence or absence of the received brown rice as the receiving detection means, and the amount of brown rice received becomes zero during the milling process under the grain residue of the input hopper 12, Then, the setting is changed so as to delay the start timing of the rice milling machine 16, and the control unit is configured to be applied when the rice milling machine 16 is started next time.

  In this way, by changing the setting so that the start timing of the rice milling machine is delayed when the amount of brown rice becomes insufficient during the rice milling, Increases and proper rice milling becomes possible.

  Accordingly, automatic adjustment of the rice milling control can be performed by a simple method of changing the setting of the start timing of the rice milling machine 16, and depending on the local circumstances of the rice bran, that is, depending on the region, the harvesting and threshing is performed by the combiner and processed by the dryer There are various cases, such as when the rice harvested with a reaper (binder) is sun-dried and then threshing, and the characteristics and bulk (capacity) of the cocoon differ depending on the region. In accordance with each local situation such as the degree of growth of rice, appropriate rice milling control can be performed without requiring special maintenance management.

(Total running control)
Moreover, about control of the starting timing of the rice milling machine 16, a control part is comprised so that change is possible according to the integrated usage-amount of the rice milling machine 16, ie, operation total time. In other words, the start timing is delayed during the period of high efficiency when the milling capacity is initially installed, and the start timing is fixed when the accumulated amount of use that stabilizes efficiency is reached. The start timing of the rice milling machine 16 can be changed so as to advance the timing. By changing the start timing, the supply of rice to the rice milling machine 16 can be adjusted to the processing capacity, including the case of the dredging process with significant fluctuations in efficiency, so if the start timing is constant, The problem that rice is cut off can be solved and stable rice milling performance can be secured.

(End control)
At the end of the operation of the rice milling machine, when the end operation or the remaining rice discharging operation is started, control is performed to stop the already used rice huller 14, so that it is provided in the housing building for the rice milling machine. If the insect screen is clogged with dust etc. due to the use of the negative pressure prevention opening over time, the inside of the machine chamber becomes negative pressure due to the operation of the hulling machine with a large air volume, and the function of the hail fan deteriorates and the milled rice As a result of the worsening of the cutting of rice, the problem that rice and rice husk are likely to be mixed with the polished rice after the end operation is solved, making the best use of the fan's ability to remove the rice and also saving power.
