  However, in the rice huller of the rice hull milling equipment having the above-described configuration, when the rice hull milling process is approaching the end, the removal rate decreases due to the reduction in the amount of rice hull supplied to the head of the hulling rice mill, and this rice hulling is insufficient When the unpolished brown rice is put into a rice mill, it is sent to the white rice tank with the rice husks remaining, so unless it is removed, the problem of mash mixing is inevitable.

  The problem to be solved is that a certain degree of milling can be ensured with respect to the total amount of the input rice bran including the treated rice that is insufficiently milled immediately before the end of the milled rice without complicating the apparatus configuration. The purpose is to provide the milled rice equipment.

According to the first aspect of the present invention, there is provided a feeding hopper (12) for feeding rice bran or brown rice, a rice huller (14) for carrying out a rice hulling treatment for rice cake, and a rice treated by the rice huller (14). Selected by the rice mill (16) for whitening, the pressure plate at the outlet of the rice mill (16) for adjusting the degree of milling, the operation unit (11a) for selecting the degree of milling, and the operation unit (11a) A control unit for controlling the compression plate based on the degree of milling performed,
When brown rice is put into the charging hopper (12), the rice milling process is performed by the rice milling machine (16) without performing the rice hulling process by the rice milling machine (14), and when the rice bran is put into the charging hopper (12) In the milling machine for rice milling, the milling process is performed by the milling machine (14) and then the milling process by the milling machine (16) .
For rice bran or brown rice received in the input hopper (12), a rice type identifying means (12d) for identifying any of the corresponding types is provided,
When the control unit detects a signal just before the completion of the rice milling operation, when brown rice is put into the feeding hopper (12), the whitening selected by the operation unit (11a) until the rice milling machine (16) stops. Control to perform whitening treatment at the same degree,
When the rice bran is put into the charging hopper (12), it is controlled to perform the whitening process by further increasing the whitening degree from the whitening degree selected by the operation unit (11a) until the rice milling machine (16) stops. It is characterized by that.

According to the above configuration, the rice bran received by the rice mill is processed into brown rice and passed to the rice mill, and the brown rice passed to the rice mill is refined at a predetermined degree of milling, so that the rice bran is polished. , The rice milling machine determines the degree of whitening by the control unit until the end based on the detection signal that detects the timing of rice that has become unfinished due to a decrease in the amount of dredging at the end of rice milling. Operation is controlled and this whitening process compensates for the lack of hulling .

Since the rice milling equipment of claim 1 can compensate for the deficiency of the treated rice with insufficient rice milling by adjusting the degree of whitening in the rice milling process after the end of rice milling in the process of rice milling rice, Without incurring the complexity of the apparatus configuration, it is possible to secure a certain degree of whitening for the total amount of rice bran including just after the end of rice milling, and to carry out rice milling .

Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.
As shown in FIG. 1, a system development diagram of one example of the rice milling rice equipment is provided with an input hopper 12 that receives the input grains and a white rice tank 13 that can extract the grains facing the guest room. In addition, the first elevator 14e for discharging the grain received from the charging hopper 12 to the upper level, the huller 14 for crushing the grain received from the first elevator 14e by the hulling roll 14a, and the huller In order to vibrationally sort foreign matter in the grain received from 14, the foreign matter sorter 15 in which the rice selection outlet 15 b and the remaining rice outlet 15 c are arranged at the front and rear ends, and the grain received from the rice selection outlet 15 b are discharged to the top. A second elevator 16e, a rice mill 16 that polishes the grains received in the brown rice tank 16t from the second elevator 16e and supplies the grain to the white rice tank 13, and a control unit that performs overall control thereof are configured.

  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 rice milling equipment divides a machine room 2 and a guest room 3 as an operation space on its front side by a partition wall 11 in a rectangular building 1. 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 end of the transfer duct 16d is opened to the basket take-out 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.

(Operation control)
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.

  As the rice hull milling machine is activated, the rice hulls put into the charging hopper 12 are subjected to the rice hulling and foreign matter sorting process by the first elevator 14e through the rice huller 14 and the foreign matter sorter 15. When brown rice is introduced, it is discriminated by the rice seed sensor 12d, and passes through the rice huller 14 with the hulling roll 14a open, and enters the foreign matter sorter 15. Further, the rice is processed by the rice mill 16 from the second elevator 16e and can be taken out from the white rice tank 13. The charge tank 16c temporarily stores treated rice from the initial milled rice.

(End control)
When the total amount of rice bran to be processed is nearing the end of rice milling, the control unit stops the rice milling machine after a lapse of a predetermined time based on a signal for detecting that rice milling is about to end Until all the devices are stopped, after the rice milling process for a predetermined time including the initial milling process rice temporarily stored in the charge tank 16c, the whole amount is discharged into the white rice tank 13. At this time, the degree of milling of the rice milling machine 16 remains constant when the brown rice is introduced, but when the rice bran is introduced, the milling degree is further increased to control the operation. The detection that the milling rice is about to end is determined by detecting that the grain sensor 12b of the input hopper 12 is turned off, and the brown rice tank lower limit sensor 16b is turned off. You may determine by the detection of withdrawal.

  By configuring the rice bran milling equipment as described above, the rice bran received by the rice milling machine 14 is processed into brown rice and passed to the rice milling machine 16, and the brown rice passed to the rice milling machine 16 is polished at a predetermined milling degree. As a result, the rice bran is milled, the milling degree is increased just before the milling process is finished, and the milling machine 16 is controlled to operate. By the milling process of this rice milling machine 16, there is no shortage of milling until the end. It is compensated and a certain degree of whitening can be secured for the total amount of cocoons.

  Further, in place of the milling degree adjustment of the rice milling machine 16 or in conjunction with the milling degree adjustment, the switching valve 16j is controlled so that a larger amount of the initial milled rice is stored in the charge tank 16c than when the brown rice is introduced. However, by adding it to the rice mill 16 just before the end of the rice milling rice, the milling pressure can be processed with a longer circulation time for a larger quantity than when brown rice is added and a sufficient amount is filled in the rice mill, so that the milling process can be performed. Can be secured to compensate for the lack of hulling.

(Start process)
Next, a description will be given of a control process associated with rice type discrimination when starting up the rice milling machine.
As shown in FIG. 5, the processing procedure diagram in the rice milling rice mill equipment equipped with rice seed discrimination means of rice bran / brown rice by the rice seed sensor 12d of the input hopper 12 is shown in FIG. 5 before the user selects the whiteness button 11d. If discrimination is not possible (S1, S1a), the rice cracker milling equipment is activated (S2-S5) by enabling selection of rice cracking, and discrimination processing after a predetermined time has elapsed after activation even if “brushing” is selected If the rice bran is discriminated in (S6), the whiteness of the polished rice is forcibly changed to “standard” (S7), and the control process is configured to display the corresponding lamp.

  Regarding the whiteness in the rice milling process, if the whiteness of the rice bran is “blowing”, the pressure of the rice milling machine is lower than “standard” and the rice bran tends to be mixed. By changing the degree to “standard”, the above-mentioned trouble can be prevented, and the change of handling can be easily recognized by the user by the lamp display.

  For the above control configuration, when the process up to the rice milling machine is activated in advance to determine the rice type, the rice type is determined before the whiteness button 11d is selected after the fee is charged. In the case of “籾”, the control configuration can be made such that “brightness” whiteness selection is not allowed. Therefore, it is possible to eliminate a sense of incongruity caused by whiteness being forcibly shifted to “standard” as a result of determining “籾” after activation.

Next, whiteness control for wrinkles will be described.
When rice is discriminated by rice type discrimination, whiteness control different from that of brown rice is performed. With regard to the whitening pressure for whiteness adjustment, for example, when the setting position of the rice polishing pressure from zero pressure to the maximum pressure is set to a range of 0 to 15, the whiteness processing of brown rice is white, standard, and eight. For each of the five whitenesses, the pressure is set according to the rice polishing positions of 12, 10, 9, and 7, respectively. On the other hand, the whiteness processing of the koji is the top white, standard, each of the eight whitenesses. Is set to a higher pressure setting according to the rice milling positions of 13, 12, 10, and 9, respectively.

  By setting the pressure according to the rice variety in this way, the whiteness selection with the same feeling as brown rice for the rice bran makes it possible to prevent the mixture of the rice cake without forcing the user to control the whiteness of the white rice. be able to.

Next, handling in the case where the target amount is small at the time of processing for wrinkles will be described.
If the user selects the whiteness of the rice cracker, and the rice varieties that have been input are determined to be rice bran and the rice milling equipment is activated, it is determined that the processing is a small amount. Since milled rice contains a relatively large amount of rice bran, the following control process is performed to prevent such a situation.

  Circulating rice milling is performed while milling at a "brushing" position or at a rice milling position at a lower pressure. The determination of the “small amount” is based on whether or not the on-time of the grain sensor 12b of the charging hopper 12 is less than a predetermined time. After the start of the rice milling machine, it continues at the set whiteness position even after the end of the normal initial rice milling cycle, and the circulation rice milling is performed until the completion of the remaining rice discharging of the stone remover. The milled rice is discharged into the cabin on condition that the grain sensor 12b of the charging hopper 12 is on. By performing the control process in this manner, it is possible to fly about the wrinkles.

(Sensor abnormality processing)
Next, control of the rice milling rice equipment when the sensor is abnormal will be described.
If the brown rice tank full sensor 16f that detects the fullness of the brown rice tank 16t in the upper part of the rice milling machine is turned on within a predetermined time after the start of the rice milling machine, the interlock by the sensor signal is released and the processing is continued. . By controlling the operation in this manner, it is possible to avoid the operation stop due to the sensor abnormality and to continue the processing, and to reduce the number of failure stops.

  Similarly, when the brown rice tank full sensor 16f for detecting the tank full level is turned on within a predetermined time before the brown rice tank lower limit sensor 16b for detecting the empty of the brown rice tank 16t is turned on, the brown rice tank full level is also detected. The interlock associated with the sensor signal of the quantity sensor 16f is released and the process is continued. Thereby, the process is continued while avoiding the operation stop due to the sensor abnormality, and the number of failure stop can be reduced. If the brown rice tank is on after a predetermined time has elapsed, interlock control is performed.

(Brown rice switching part)
Next, the configuration of the brown rice switching unit will be described.
The brown rice switching device 14c is constituted by an electric switching valve, and is switched when returning the grain guided from the elevator throw 14h to the stone remover 15 to the cabin 3 side. Conventionally, the brown rice switching device 14c and the elevator throw 14h are individually configured, the elevator throw 14h is provided with an inspection port, is configured in a complicated manner by bolted flange connection, and is individually installed and removed for maintenance. In addition, many man-hours are required to align the switching valves.

  In order to solve the problems associated with the above-described configuration, the brown rice switching device 14c is integrated with the elevator throwing port 14h as shown in FIG. 6 in its main part configuration diagram (a) and B arrow view (b). The opening for attaching the motor base 14b of the brown rice switching device 14c serves as an inspection port, and the set of switching valves is configured to be separable from the casing when the mounting bolt of the motor base 14b is removed.

  By configuring in this way, the connecting flange is eliminated, the casing configuration is simplified, and the integrated handling of the switching valve of the brown rice switching device 14c can be easily installed / removed without requiring adjustment of the mounting of the motor shaft, In addition, a simple configuration in which the opening of the motor base 14b is used as an inspection port enables integrated internal maintenance without requiring an inspection port for the elevator throwing port 14h.

(Kashiwa removal department)
Next, the configuration of the cocoon extraction unit will be described.
As shown in FIG. 7, the basket take-out portion 16 p is configured to communicate with the cabin transfer duct 16 d so as to face the cabin 3, and is provided with a hood 16 h surrounding it. The bottom portion of the hood 16h is formed in a transmission type through which the cocoon can pass, and the spilled cocoon is configured to enter the machine room. By configuring in this way, even if a bag is spilled when the user sets the bag B in the bag take-out portion 16p and takes the bag home, it does not scatter to the cabin 3 side, and the beautification in the cabin can be maintained. it can.
