Problems solved by technology

If the bran flakes are attached to the endosperm again, even though the bran has been removed by grinding, the part of the endosperm where the bran has been removed may be misidentified as "the pericarp, seed coat, or aleurone layer."

Embodiment Construction

[0031] Hereinafter, modes for implementing the present invention will be described with reference to the drawings. figure 1 It is a schematic explanatory drawing which shows the structure of the rice grain discrimination apparatus for carrying out the grinding degree evaluation method according to one Embodiment of this invention. Reference numeral 1 is a tool used in the dyeing process (S3) of dyeing rice grains using a dyeing solution. Reference numeral 2 is an imaging device for observing the color of dyed rice grains (used in an irradiation step ( S7 ) and an image acquisition step ( S8 ), which will be described later). Reference numeral 3 is a discrimination device (computing device) that calculates the degree of finish of rice grains (used in the degree of finish calculation step ( S9 )) based on the image captured by the imaging device 2 .

[0032] The instrument 1 used in the staining step may include a test tube rack 4 , a test tube 5 supported by the test tube rack...

Abstract

The present invention provides a grain grinding degree evaluation method and device thereof capable of suppressing misidentification between a bran part and an endosperm part and having no individual differences. The method for evaluating the degree of fineness of cereals includes: a dyeing step of dyeing grains with a dyeing solution; an irradiation step of irradiating the grains with light; an image acquisition step of acquiring an image of the grains irradiated with light; and a step of determining the degree of fineness of grinding. , for each of the plurality of pixels constituting the image of one grain acquired by the image acquisition step, it is distinguished whether it corresponds to the bran part or the endosperm part based on a predetermined criterion, and the pixel corresponding to the bran part When there are more than a predetermined number or a predetermined ratio, it is determined that the grains corresponding to the image composed of a plurality of pixels are defective grains with residual chaff.

Description

technical field [0001] The invention relates to a method and a device for evaluating the degree of fine grinding of cereals. Background technique [0002] Conventionally, it has been known that digestion and absorption and mouthfeel are improved by removing the outer skin of the grains and making them refined white grains. In the case of rice grains, brown rice as a raw material is supplied to a rice polisher and polished (polished) to remove bran and process it into polished rice. Moreover, the yield when brown rice is processed into polished rice, that is, the weight ratio of polished polished rice to brown rice is displayed on the product. This yield is also related to the degree of whiteness of polished rice. That is, as the number of polished rice increases, the weight of the rice grains decreases (the weight decreases by the amount of the bran layer removed. The removal rate of the bran at this time is called the yield, or the degree of polishing, or the degree of wh...
