[Detailed description of the invention] Komei Ki (Related to automatic polishing level control device) 0) 1
'', Seishaku 1. GEH+ 111''■ Evening/Monday 1. This is a device that automatically controls the IIf calendar-type lees rice polishing f1 and mills C unpolished rice into white rice for rice with a polishing level f.

1. The degree of polishing of rice for rice is determined by the degree of polishing of the sticky layer that remains on the rice grains after processing the rice grains.

Brown rice flour (,1 consists of a starch layer, or endosperm, surrounding the outer periphery of the core, ij I: Yue 1, j
The outer bran layer consists of the inner bran layer, the outer n11 layer (which forms the outer wall, the pericarp, and the seed coat on the inner wall surface of the seed), and the inner bran layer consists of the ectosperm and the IM powder layer. The irises become 1, and in mature rice, the culm is thin, which is similar to that of good quality rice.
□′becomes. 11. Pour the powder with the layer removed black. After removing the inner layer, the powder is called white rice bran. Sunset 111th floor Ll.

Usually 42-48μ, inner phase (layer is 25-4.0μ, the degree of polishing is determined by the thickness of the aleurone layer of the inner bran layer, and the quality of polished rice is evaluated. 1M $5) The layer contains proteins and fats and oils that give it flavor, so it is glue26)
72 becomes an important component of white rice for edible rice, and white rice from which the aleurone layer has been removed is used for starch white rice and sake brewing.

Conventionally, the whiteness of white rice was measured visually and used as a substitute for whiteness Jrt, but this value was determined by measuring the amount of light diffused from the rough surface of the white rice grain E4 surface. However, there is an iIQ ``C'' which is completely unrelated to the degree of polishing.For example, white rice with a slight amount of white bran after milling is shown as white rice J, which has been thoroughly removed and polished, and a white melon with a high 11n is obtained. .This (, 1 is the opposite value ζ for the progressing polishing degree
゛Is it 1?The polishing level is 11 ((Prove that the relationship is full.)
With F, when the rice grains 101 become shiny and dense, the amount of light decreases in the direction of the surface repulsion.
There is day C. The thickness of the aleurone layer, which indicates true whiteness, is 21. jB>! 1) i:'r of the circumferential surface of the breasts
The amount of diffused reflected light is 0 and the amount of irregularity on the outer circumferential surface is 0. The amount of light becomes white. Measure CJ=J It is possible to determine C by using statistical curve values obtained through experiments in relation to the light intensity of the ray and the yield factors. J5, the light Ii'1 of the light beam transmitted through the polished rice grain is changed by Cj+j; By measuring h1 and compensating the amount of light η, it is possible to measure the amount of lees white.

Next (This box rice white 1 is the negative 1r of the rice polishing machine: J is the flow rate of rice.
Since the milling level is 31 and the rice is milled at 1 level, it is connected to the pre-control device and added to the predetermined level of milling.By automatically controlling the load, the level of milled rice can be adjusted. It is possible to maintain and manage it at a constant level.

Since the load of rice milling 1 is due to the resistance C that appears in the rotational force of the milling trochanter, there is a multiplicative product of the friction nozzle of the rice grains in the milling trochanter and the circumferential surface speed of the milling trochanter, and therefore 'C friction. The load can be controlled by adjusting either the normal pressure angle or the speed.

The L force is adjusted depending on the pressure at the IJI outlet or the white wall.
However, when an external force is applied, there is a time lag before the rotational force of the white trochanter shows a reaction, so it is instantaneous. ]
i+ij is in trouble! #IL'r, this time difference has the drawback of causing a banding phenomenon. - On the other hand, if the rotational speed of the polishing roller A is adjusted to 1iij, the immediate response of the adjustment I'1ii will appear and sensitive load adjustment will be possible.

Pressure adjustment does not significantly modulate the characteristics of the whitening action, but instead has a negative (51 wave 1J [In some cases, there is a misadjustment due to banding! :): 1 speed. If RIV flii Ni J, Ruto e L: I, In Ij action's 17 is ``modulated in a strange way'' (Go, Portrait i'au: j has a vibrational - no C and Min 1. P. There is the convenience of being able to stop damage caused by the support.

:1,ta, :'I'f R[! rl'J The triangular angle of the rotation speed of the white trochanter +, 1 +, 1:,; Lees action 1) It is related to rice action 1, and generally, ? The heavy cutting action of IJI milling rice polishing is proportional to the peripheral speed (circumference x number of revolutions) of the IJI white trochanter, but if the number of revolutions is too high, the rice grains may become spherical or they may become crushed. If the number of rotations is small, the milling efficiency will be extremely high (C゛ of the downhill rice milling machine (Rhombus), ``The white trochanter competes at about 1000 revolutions per 10 minutes.

In addition, the rubbing method 1'11 rice 1 Iku C) is applied to prevent the occurrence of crushed grains. Basically, the rotation speed after whitening is reduced and the middle blower type is used.
There is about ε00′C. Therefore, at the time t17, the number is increased or decreased by a large amount, and Ct) as mentioned above (σ1 reduction action, 13 ruru1
