摘要： PURPOSE: To accurately estimate sample temperature by a near infrared ray spectral analysis method even if a moisture content is fluctuated. CONSTITUTION: Wavelengths of 1450nm and 1930nm are selected as main wavelengths. And a near infrared ray is emitted from a lamp 11, an emitted near infrared ray is reflected through a slit 12 by a plane mirror 13, and a reflected near infrared ray is made incident on a grating 14. The main wavelength is light-separated from the near infrared ray through the grating 14 and an order source 15 and a sample S is irradiated with it. And reflected light from the sample S is detected by a reflected light detection part 18, a degree of light absorption is found, and the degree of secondary differential light absorption is found from the obtained degree of the light absorption. And the degree of the secondary differential light absorption is made an explanation variable, temperature of the sample is regression-analyzed as an object variable, and a calibration curve for finding unknown temperature of the sample is made. And the degree of the secondary differential light absorption is found on the unknown temperature of the sample and the temperature is estimated from the calibration curve.

摘要： PURPOSE: To estimate a component value of hulled rice even in a state wherein unhulled rice is mixed therein after hulling and thereby to execute quickly and accurately assortment of the unhulled rice received. CONSTITUTION: The relationship between the rate of mixing-in of unhulled rice and a component value of hulled rice is determined beforehand as to a standard sample of which the rate of mixing-in of unhulled rice is known, by a method of near infrared analysis, and then the rate of mixing-in of unhulled rice of a sample of inspection is measured. The corrective amount of the component value of hulled rice of the sample of inspection is determined on the basis of the aforesaid relationship between the rate of mixing-in of the unhulled rice and the component value of hulled rice, the component value of hulled rice with the unhulled rice mixed in of the sample of inspection in the state of the unhulled rice being mixed in is corrected on the basis of this corrective amount of the component value of hulled rice and the component value of pure hulled rice in a completely hulled state of the sample of inspection is estimated therefrom. Even when the unhulled rice received by a rice center is hulled as it is, in an undried state, and a large quantity of unhulled rice is mixed in, an accurate component value of the pure hulled rice can be known immediately, since the component value of hulled rice (the component value of the pure hulled rice) in a state wherein no unhulled rice is mixed therein can be estimated in the state wherein the unhulled rice is left mixed in the hulled rice, and thus the efficiency and accuracy of assortment of raw unhulled rice at the rice center or the like can be improved.

摘要： PURPOSE:To realize total evaluation of grain based on measurements by measuring the sanitariness for predicting the number of microorganism along with the apparent grade and internal quality inspection. CONSTITUTION:A grain quality measuring means 1 lifts a single grain fitted in a disc 6 rotating about an inclining shaft 5 and an optical measuring mechanism 7 irradiates the grain with visible light and receives a reflected light or a transmitted light. An internal quality measuring means 2 analyzes the components and physical and chemical properties or the qualitative characteristic values, e.g. the taste, of uncrushed unpolished rice by near infrared spectroscopic analysis. A sanitariness measuring means 3 previously fills a measuring container 18 placed in a dark measuring room 17 with a liquid for separating and extracting microorganisms from the grain. The concentration of adenosyl triple phosphate is then measured by injecting luciferin-luciferase through an injection port 22 of the measuring room 17 and the number of microorganisms is estimated. A computor 4 averages the measurements received from the measuring means 1, 2, 3 and determines the grade, quality and sanitary aspect.

摘要： PURPOSE:To adjust water quantity always accurately by calculating the flow rate per a unit time with a control device based on the number of rotation per the unit time at a flow rate sensor of a water feed pipe and opening a closing device of the water feed pipe until the integrated flow quantity reaches a designated value. CONSTITUTION:A rice cooker is set under a rice washer 3 to wash the polished rice supplied from a rice bin, to adjust water, and to perform impregnation. A closing device 36a (and 36b), a flow rate sensor 34 and an operation device are set on a water feed pipe 35. A control device 20 of the closing device 36a is set in the rice washing and cooking device. The control device 20 accumulates the flow rates per a very small unit time based on the number of the rotation pulse of the flow rate sensor 34 to rotate per a unit time or the time required to count the designated pulse number by the flow rate sensor 34. The control device 20 controls the water feed by opening the closing device 36a until the accumulated value reaches a designated value. Thus, the water adjustment is accurately performed.

摘要： PURPOSE:To make possible the judgement of the propriety of the calibration curve of a measuring sample at a stable accuracy by comparing the results of calculation of a target value of a reference sample with an existing data while the plotting absorbances of both reference and measuring samples is conducted to respective calibration curves. CONSTITUTION:Measured average values Rxi and RHi are determined for a measuring sample and a high-level reference sample. Then absorbances are calculated 15 by absorbance ODji=-logRoi (average value, (i) represents a filter)/Rji (J=0, L, H). A target value yj is determined based on a preset calibration curve. Here, the formula of yj=Ko+SIGMA(Kj.ODji) and constants k0 and kj are set for each component to be determined. A comparison processing is performed to determine the presence of a deviation as for the target values yL, and yH of the reference sample thus obtained from a value stored previously by chemical analysis or the like. When the deviation is not found, it is estimated that the deviation does not exists or very limited, if any, in the calibration curve of the measuring sample too and a target value yx is displayed 16. When the deviation is found, the target value yx is corrected by the value of the deviation and a corrected value y'X obtained is displayed 16.
