Description

  The present invention relates to a resistor adjusting method and a resistor adjusting jig in a grain refiner.

  As a conventional grain refiner, there exists a thing of patent document 1, for example. This technique will be described with reference to FIG. FIG. 7 shows a part of the grinding roll 102 in a state in which a plurality of grinding rolls 102 and a plurality of spacers 103 are alternately stacked in the vertical direction to form a grinding roll body, which is fitted to the main shaft 101. . In this figure, a porous cylindrical body 105 is provided outside the grinding roll 102 in the radial direction so as to be spaced apart from the grinding roll 102 so as to form a whitening chamber 104. The porous cylindrical body 105 is disposed between the columns 106 adjacent to each other in the circumferential direction. FIG. 7 shows four columns 106 and four porous cylindrical bodies 105. Each column 106 is provided with a resistor 107 that protrudes toward the milling chamber 104 and imparts resistance to the movement of the grains in the circumferential direction of the grinding roll 102. The resistor 107 is vertically arranged in a long shape in the axial direction of the main shaft 101.

  Furthermore, each strut 106 is provided with a protrusion amount adjusting means 108 for independently adjusting the protrusion amount of each resistor 107 in the radial direction, and the protrusion amount of the resistor 107 is manually adjusted (arrow in FIG. 7). reference). In addition, the code | symbol 109 in a figure is a support | pillar cover, the code | symbol 110 is a dehulling room cover, and the code | symbol 111 is a grain discharge basket which discharges | emits the grain after refined.

  The operation of the above configuration will be described. Since the distance between each resistor 107 and the outer peripheral surface of the grinding roll 102 can be independently adjusted by the protruding amount adjusting means 108 provided on each column 106, the grains in the milling chamber 104 can be adjusted. The resistance to the flow of rice grains can be adjusted independently, and as a result, the resistance state against the flow of rice grains can be finely adjusted / changed according to the characteristics of the moisture and varieties of the raw materials and the form required for products such as split rice. There is.

  However, in the above-described grain refiner, there are a plurality of protrusion amount adjusting means 108 provided on each column 106 (in FIG. 7, four positions are shown in the circumferential direction, and a plurality of positions are provided in the direction of the main shaft 107). There is a case where it is provided). In addition, depending on the operator, there are cases where adjustment by the protrusion amount adjusting means 108 is unfamiliar, or the adjustment amount is determined visually depending on the experience and intuition of the operator. For example, if the gap between the resistor 107 and the outer peripheral surface of the grinding roll 102 is set to be extremely narrow, there arises a problem that rice grains are sandwiched in the gap and broken rice is generated. On the contrary, if the gap between the resistor 107 and the outer peripheral surface of the grinding roll 102 is set to be extremely wide, no resistance is generated in the flow of rice grains. As a result, the rice grains do not reverse during milling, and uneven graining occurs throughout the grains. Cause problems.

Is shown to measure the gap between the stripping wire mesh tube 6 and the whitening roll 5. FIG. 4 is a perspective view showing the entire resistor adjusting jig 16. This resistor adjusting jig 16 has a plurality of measuring parts having different outer diameters (for example, five round bars shown in FIG. 4) connected to one end side of the main body 17 which becomes a grip part during adjustment work.

Example 1
Hereinafter, an example will be described in which the value of the gap between the resistor and the outer peripheral surface of the grinding roll can be accurately selected according to the properties (moisture, variety, etc.) of the brown rice, regardless of the experience and intuition of the operator. .

  Table 1 shows the yield (prior art) when the gap between the resistor 11 and the grinding roll 5 is constant and the gap between the resistor 11 and the grinding roll 5 for the three types of brown rice used as raw materials. The yields (test zone 1, test zone 2, and test zone 3) when changing the gap C, the gap D, and the gap E and finely squeezing are compared and compared. At this time, the indications of the gaps B, C, D, and E correspond to the reference numerals B, C, D, and E of the resistor adjusting jig shown in FIG.

As shown in the column of prior art in Table 1, the value of the gap between the resistor 11 and the grinding roll 5 as B (8 mm) regardless of the nature (moisture and variety) of brown rice The yield was 90.5%, the yield of brown rice B was 90.1%, and the yield of brown rice C was 89.5%. It was found that even in the same gap, the yield difference was about 1.0% due to the properties of brown rice. Therefore, as shown in the columns of Test Zone 1, Test Zone 2 and Test Zone 3 in Table 1, a test was performed in which the gap between the resistor 11 and the grinding roll 5 was changed according to the properties (moisture and variety) of the brown rice. It was. As a result, the best yield of brown rice A was 90.7% of the gap C (7 mm) in the test area 1, and the best yield of brown rice B was 90.4% of the gap D (6 mm) in the test area 2. The best yield in C was 90.3% of the gap E (5 mm) in the test section 3.
From the above test results, it was found that the yield was improved by appropriately selecting the gap according to the properties (moisture and variety) of the brown rice.
At this time, determining the adjustment amount visually by relying on the experience and intuition of the operator as in the prior art is to select an appropriate gap according to the properties of the brown rice because the adjustment amount is about several millimeters. It is impossible. Therefore, by using the resistor adjusting jig shown in FIG. 3, the gap between the resistor and the outer peripheral surface of the grinding roll can be adjusted accurately.

  As described above, when adjusting the protrusion amount of the resistor toward the polishing chamber, the resistor adjusting jig provided with a plurality of measuring portions having different outer diameters according to the properties of the brown rice to be refined is used. Depending on the properties of brown rice, insert one measuring part corresponding to the brown rice to be refined in the resistor adjustment jig into the gap between the whitening roll and the resistor, and determine the distance between the whitening roll and the resistor. Therefore, the gap between the resistor and the outer peripheral surface of the grinding roll can be accurately adjusted regardless of the experience and intuition of the operator. In particular, by using a resistor adjustment jig equipped with a plurality of measuring units, the value of the gap between the resistor and the outer peripheral surface of the grinding roll can be accurately selected according to the properties of the brown rice, and the yield can be improved. The merit that it is possible to occur.

  The present invention can be applied to a vertical or horizontal grain mill, and the present invention is mainly applied to a grinding grain mill in which the surface of a milling roll is formed in a grindstone shape. For example, if a long resistor that provides resistance to the movement of the grain in the circumferential direction of the milling roll is provided on the side of the stripping wire mesh cylinder, it is also applied to the friction type grain mill. be able to.
