DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for calculating a blend ratio of brown rice and other rice.

[0002]

2. Description of the Related Art There is a method of setting a blending ratio of brown rice based on a taste evaluation value based on an amylose and a moisture value (Japanese Patent Laid-Open No. 62-22828). When it is done, it is not possible to secure a stable taste of blended rice. In other words, if the blend ratio is set empirically from the varieties, production areas, and production years as in the past, the degradation degree of the rice varies, even for new rice and old rice, and the quality will not be stable if blended at a constant ratio .

[0003]

Means for Solving the Problems] The present invention, on SL disadvantage of
It is intended to more accurately grasp the degree of degradation of the blended rice using the detection of fatty acidity or a degree of degradation related thereto as one of the degradation indicators of rice, The following technical measures were taken: That is, all blends
Designating means to designate rice and supply of these designated rice
Means for detecting the degree of fatty acid in response to the detected fatty acid degree, means for setting the estimated degree of fatty acid or the degree of deterioration associated therewith when blending the designated plurality of rices ,
A method for calculating a blend ratio of rice, comprising a blend ratio calculating means for calculating a blend ratio so as to reach a set predetermined target value.

[0004]

Blurring of rice stored to the operation and effect of the invention a plurality
When the rice to be imported is specified, the specified rice
Is measured. Then the estimated fat after blending
A target value of the acidity or the degree of deterioration related thereto is determined,
The predetermined target value is set by the blend ratio calculating means.
The blend ratio can be calculated.

[0005] Therefore, not only blending based on varieties, production areas, and production years, but also the degree of fatty acid content, which is a deterioration index of rice, is grasped and used as a reference for blending .
Stabilize the quality of blended rice by taking into account the condition of rice
effective.

An embodiment of the present invention will be described with reference to the drawings. A plurality of brown rice tanks 1a, 1b... Store different types of brown rice, etc., and the tanks 1a, 1b. You. The discharge shutter 4 to be provided at each discharge port of the tanks 1, 1,... Is switched from a discharge port block state to a small discharge state and a normal discharge state. Supplied as a sample to

The fatty acid degree detecting means 5 calculates the absorbance at a predetermined wavelength of transmitted light or reflected light obtained by irradiating a miniaturized sample (or a sample as it is) with near-infrared light, thereby obtaining a computer program. The calculation unit 6 is configured to calculate the fatty acid level. Here, the brown rice A ₁ is stored in the brown rice tank 1a, estimated fatty degree FAb when blending the brown rice A ₂ which is stored in brown rice tank 1b is measured fatty degree FA ₁ and rice A brown rice A _{1 Two}
FAb = FA ₁ + αFA _{2 where} the measured fatty acid degree is FA ₂ and the blend ratio of brown rice A ₂ to brown rice A ₁ is α (0 <α <1). Accordingly, a predetermined target value estimated fatty degree FAb, for example if 30, α = (30-FA 1) / FA 2 , and the fatty acids of the brown rice A ₂ when fatty degree FA ₁ brown rice A ₁ is 20 Figure 2 shows the relationship between FA ₂ and blend ratio α.
It becomes as shown in.

[0008] Thus the fatty acid of FA ₁ brown rice A ₁ is apparent, the blend ratio of the unpolished rice A ₂ alpha is obtained (blend ratio calculating means), these calculations to the display section 7 with performed by the calculator 6 Can be displayed. In addition, 8 is an elevator for supplying raw brown rice, 9 is an elevator for mixing rice tank 10, 1
1 is a rice mill.

[0009] In the above configuration, specifying brown rice to be blended, first fatty acid of FA ₁ brown rice A ₁ is measured (step 10), followed by fatty acid of FA ₂ of brown rice A ₂ is also measured in the same manner (step 20 ). A target value of the estimated fatty acid degree FAb after blending is determined (step 30), and a blend ratio α is determined based on the above calculation formula (step 4).
0).

After that, when the cost data and the weighing data of each brown rice based on the blend ratio are inputted (step 50), the selling price is calculated (step 60) and they are displayed on the display unit 7 (step 70). In the above-described embodiment, the blend ratio α is directly calculated from the values of the fatty acid degrees FA ₁ and FA ₂ of brown rice. However, the degree of deterioration Z based on the fatty acid degree may be calculated. That shows the relationship between the degree of degradation Z for commonly fatty acid (FA), as shown in FIG, deterioration degree Z ₁ and degradation degree Z ₂ brown rice A ₂ of brown rice A ₁ are each, Z ₁ = f (FA) ₁ , Z ₂ = f (FA) ₂ , and the degree of degradation Zb after blending is Zb = Z ₁ + αZ ₂ . Here, assuming that the target value of Zb is Zb ₀ , the blend ratio α is obtained from known Z ₁ and Z ₂ .
