Claims

[Scope of Claim for Utility Model Registration] (1) A device for continuously measuring the whiteness of brown rice, (a) a brown rice channel through which brown rice flows continuously at a predetermined density, (b) a light source, ( c) a photoelectric element; (d) first and second optical paths guiding light from a light source; and (e) a chipper having a blade that rotates in one plane and selectively blocks light in the two optical paths. (f) an irradiation light optical fiber for guiding the light of the first optical path from the downstream side of the tipper to the brown rice flow path in order to irradiate the brown rice flow with the irradiation light; and (g) a reference light. (h) a reference light optical fiber for guiding the light of the second optical path from the wake side of the chipper to the photoelectric element in order to irradiate the photoelectric element; a reflected light optical fiber for guiding reflected light to the photoelectric element; (i) a tipper position detector for detecting a blade rotation position of the tipper; a separation circuit that synchronizes the signal of the detector and separates the signal of the photoelectric element into a reflected light detection signal, a reference light detection signal, and a dark current signal; Subtract the value to obtain the brown rice detection whiteness value, and
A reference whiteness value is obtained by subtracting the value of the dark current signal from the value of the reference light detection signal, and the true whiteness value of brown rice is determined by comparing the brown rice detection whiteness value and the reference whiteness value. A brown rice whiteness measuring device having an arithmetic circuit and. (2) Utility model registration In the whiteness measuring device according to claim 1, the arithmetic circuit calculates a true whiteness value based on a ratio between the brown rice detected whiteness value and the reference whiteness value. A whiteness measuring device designed like this.
