  The production of laver products (dried laver) is generally made from a laver mixture that is made by mixing seaweed raw algae and water, and the washing process, dehydration process, kneading process, cutting process, aging process, blending process, laver extract It consists of a manufacturing process and a drying process. The method for judging the quality of the laver mixture of the present invention and the use of the display board for judging the quality of the laver mixture are performed in the production process of the laver product, and may be performed at any stage after the washing process and the dehydration process. Good. However, it is desirable to carry out after the washing step and the dehydrating step before the adjustment of the laver mixture. Alternatively, it is desirable to carry out after the cutting step in order to dissolve the water-soluble substance more.

  The seaweed mixture, which is the target of judging the quality of the seaweed mixture, is a mixture of seaweed algae and water. Or it is a mixed solution of fresh water and seawater. Even if seawater or a mixture of fresh water and seawater is used, the amount of transmitted light detected by optical means is not affected. Moreover, the water in the laver mixed solution dissolves the water-soluble substance of the laver raw algae.

  Measurement is performed by optical means. The optical means will be described with reference to FIG. A light emitting diode (LED) having a wavelength in the visible region is used as a light source, and a photodiode is used as a light receiving portion. The light source is a red LED whose light transmittance (transmitted light amount) at that wavelength is not easily affected by the quality of the laver, and this is used as a reference light source. Further, as light sources whose light transmittance (transmitted light amount) is influenced by the quality of the seaweed, there are blue LEDs, green LEDs, and orange LEDs, which are used as secondary light sources.

  The light source part is a light source (referred to as light source 1) in which one red LED (peak wavelength 641 nm) is arranged in the center of the light source and six blue LEDs (peak wavelength 456 nm) are arranged around it. A light source (referred to as light source 2) in which six LEDs (peak wavelength 517 nm) are arranged, and a light source (referred to as light source 3) in which six orange LEDs (peak wavelength 592 nm) are arranged around are used. The light source is not limited to this wavelength, and a light source whose light transmittance at that wavelength is easily or hardly affected by the quality of the seaweed is selected. Moreover, the reason why six light sources are arranged is to obtain a light amount suitable for measurement. Moreover, it may be driven by a pulse current, and the apparent average light amount may be increased as compared with the light amount during continuous light emission. An orange LED having a high light intensity per LED is advantageous in practical use. In addition, since the light transmittance of one red LED and six orange LEDs are approximately the same value, an orange LED is advantageous to improve accuracy. The light receiving unit has a structure corresponding to each light source.

  A method for determining the quality of the laver mixture will be described with reference to FIGS. 2, 3 and 4 are flowcharts of the present invention.

  The sample is irradiated with the light source a predetermined number of times for each light source, the amount of transmitted light is measured, the transmitted light signal is converted into an electrical signal in the light receiving unit, and the obtained output voltage is converted into a digital signal via the AD conversion board, Input to the arithmetic unit. In the measurement, after the red LED emits light for the first time, the blue LED, the green LED, and the orange LED emit light, the respective transmitted light amounts are output, and this output value is input to the arithmetic unit (steps 1 to 7). . The blue LED, the green LED, and the orange LED each constitute an optical means independently, and the light emission is not limited to simultaneous. Further, the order of light emission of the red LED, the blue LED, the green LED, and the orange LED is not limited.

  The average of the output voltage of each obtained light source of the predetermined times is calculated (steps 8-9). The output light quantity of the light source is constant because the apparatus is used. However, the concentration of the laver mixture flowing through the pipe of the manufacturing apparatus is not constant. Thus, since the amount of transmitted light depends on the density, the ratio of the amount of light transmitted to the red LED as the light source is determined for each sample (step 10), and the density dependency is eliminated.

  That is, the ratio of the amount of transmitted light in which the light source is a blue LED to the amount of transmitted light in which the light source is a red LED is obtained. In addition, the ratio of the transmitted light amount in which the light source is a green LED to the transmitted light amount in which the light source is a red LED is obtained. Furthermore, the ratio of the transmitted light amount in which the light source is an orange LED is obtained with respect to the transmitted light amount in which the light source is a red LED.

  The quality is judged by comparing it with an experimentally obtained ratio calculation result (empirically obtained quality judgment reference value) (step 11). The ratio calculation result obtained empirically (empirically obtained quality judgment reference value) refers to the value of the ratio calculation obtained by measuring a sample whose quality has been certified by visual inspection in advance.

  The quality is determined by classifying (step 12). The quality class can be set to, for example, three classes such as A rank, B rank, and C rank, but is not limited thereto. For example, when the quality class is set to 3 levels, the ratio calculation result (empirically determined quality criterion value) is set for each class sample and measured. A value is determined by determining which value is closest to the empirically obtained ratio calculation result (empirically obtained quality determination reference value).

  Further, the quality may be determined by comparing the measurement results obtained by the ratio calculation for each type of light source.

  From the quality determination result, the cutting form of the seaweed original algae in the laver cutting machine and / or the maturation form of the original seaweed nori in the laver ripening machine and / or the drying state in the laver dryer are controlled.

  Moreover, you may use the display board for quality determination of a nori mixed liquid in the method of determining the quality of the nori mixed liquid which evaluates the quality of nori seaweed original algae.

  In the following, examples based on practical tests of the present invention will be described.

  The measurement was performed as a laver mixed solution obtained by mixing the sample with a laver original algae and water, which are the collection conditions described below.

Sample 1 Number of times of collection First time of collection December 3, 2002 Sample 2 Number of times of collection Second time of collection December 10, 2002 Sample 3 Number of times of collection Third time of collection January 17, 2003 Sample 4 Number of times of collection 4 Time of collection January 31, 2003 Sample 5 Number of times of collection 5th time of collection Time of February 20, 2003 Sample 6 Number of times of collection Sixth time of collection March 10, 2003 Light source is a red LED as a reference light source In addition, blue LEDs, green LEDs, and orange LEDs were used as secondary light sources.

  Each sample is irradiated with the light source a predetermined number of times for each light source, the amount of transmitted light is measured, the transmitted light signal is converted into an electrical signal at the light receiving unit, and the obtained output voltage is converted into a digital signal via the AD conversion board. , Computer input. In the measurement, after the red LED first emitted, the blue LED, the green LED, and the orange LED emitted light, each transmitted light amount was measured, and the operation of inputting the measured value to the computer was repeated.

  The measurement was performed at the Sakai Industrial Research Laboratory in Nagoya City.

Table 1 Transmitted light amount of red LED and blue LED with respect to sample 1 In Table 1, the horizontal axis represents time, and the vertical axis represents the output voltage indicating the transmitted light amount. After the first red LED emits light, the blue LED emits light and measurement is performed, so that an output voltage indicating the transmitted light amount for the red LED and an output voltage indicating the transmitted light amount for the blue LED are output with a time difference. It shows that. Table 1 shows that the measurement using the reference light source and the secondary light source was performed seven times.

Table 2 Transmitted light amount of red LED and green LED with respect to sample 1 Table 2 shows the output voltage indicating the transmitted light amount with respect to the red LED when the red LED first emits light and then the green LED emits light and performs measurement. The output voltage indicating the amount of light transmitted to the green LED is output with a time difference.

Table 3 Transmitted light amount of red LED and orange LED with respect to sample 1 Table 3 shows output voltage indicating the transmitted light amount with respect to red LED by emitting the orange LED after first emitting the red LED, and measuring. The output voltage indicating the amount of transmitted light with respect to the orange LED is output with a time difference.

  The average of the output voltage of each obtained light source of the predetermined times obtained is calculated, and in each sample, the transmitted light amount (output voltage) of the blue LED, green LED or orange LED with respect to the transmitted light amount (output voltage) with the light source as the red LED. The ratio was determined.

Table 4 Ratio of transmitted light amount of each light source to transmitted light amount of red LED for samples 1 to 6 Generally, it is known that the quality of laver decreases as the number of sampling increases. In this example test, as shown in Table 4, the same tendency was obtained that the obtained ratio increased as the number of samplings increased. Therefore, based on the measurement in the present invention, the quality of the laver mixture can be determined. In addition, although there is a change in numerical values for the data collected at the third sampling, it is in line with the state of the measurement sample. In addition, it is added that the quality of seaweed varies depending on natural conditions.

  Another embodiment of the present invention will be described.

  It is a measurement performed by a plurality of optical means irradiated with an aqueous solution in which a seaweed algae and / or a water-soluble substance of the seaweed algae in a laver mixture is dissolved. In this configuration, the transmitted light amount by the optical means is selected, and the ratio of the transmitted light amount by the other optical means is calculated for each of the transmitted light amounts by the two or more optical means to be used as a reference. There is a method of judging the quality of the laver mixed liquid in which the results are compared to judge the quality. According to this method, two or more transmitted light amounts are selected as the reference for the ratio calculation, the ratio calculation of the other transmitted light amounts is performed for each reference, and the calculation results are compared to ensure more reliable quality. Can be determined.

  Moreover, the average of the measured value of the transmitted light amount of each light source of the obtained predetermined times (all measurement times or several times of all measurement times) is calculated, and the ratio calculation is performed based on the average value of the transmitted light amount In addition, irradiation with a plurality of light sources may be performed twice or more, and a ratio calculation may be performed every measurement. In this case, the quality of the laver mixture at the time of each measurement can be determined, and the measurement result and the quality of the product can be combined in terms of the production cycle. Furthermore, the average value of these ratio calculation results may be obtained, and the quality may be determined by comparing the measurement results of these ratio calculations.

  Further, the ratio may be calculated by irradiating the light source only once, and the quality may be determined from the result of measurement by these ratio calculations. In this case, measurement can be performed in a short time, and the conditions of the subsequent laver product manufacturing process can be determined more quickly.

  In the method of the present invention, the quality, properties, and market value of the nori mixture or the nori seaweed may be determined. In addition, the measurement result can be combined with the quality of the seaweed product in terms of the production cycle.

  Still another embodiment of the present invention will be described.

  Even if the quality of the nori mixture or nori seaweed algae is judged, the amount of transmitted light can be detected by optical means for each of the nori mixture, nori seaweed, and the aqueous solution in which the water soluble substances of nori seaweed are dissolved. Good. As for the measurement of nori seaweed algae, the nori seaweed algae may be set in a preparation and measured. In this case, it is possible to determine an appropriate quality according to the state of the laver product manufacturing.

  In addition, the method for judging the quality of the nori mixture is as follows: the nori seaweed and / or the nori seaweed in the nori mixture obtained by mixing the nori seaweed in the nori production process and the liquid that dissolves the components of the nori seaweed The amount of transmitted light is detected by optical means based on the wavelength dependence of the solution in which the above components are dissolved, and the method is based on the wavelength dependence and / or the amount of transmitted light, and at least the nori seaweed in the laver mixture and Measurements performed by a plurality of optical means irradiated to a solution in which components of seaweed raw algae are dissolved, wherein the measurement is performed by selecting the amount of transmitted light by the one optical means, and this one optical means It is a configuration for calculating the ratio of the amount of transmitted light by other optical means to the amount of transmitted light by the method of determining the quality of the seaweed mixed solution in which the quality is determined based on the measurement result by this ratio calculation .

  Thus, you may comprise a nori mixed liquid from liquid other than nori seaweed and water. Examples of liquids other than water include alcohols such as ethanol. In this case, the amount of transmitted light is detected by optical means on the basis of the wavelength dependence of the solution in which the components dissolved in the liquid used among the components of the seaweed algae and / or the seaweed algae are dissolved. In this case, it is possible to measure the amount of the specific component dissolved in the liquid used, and to measure the content of the specific component of the seaweed product to be manufactured.

  In this case, for example, the quality of the seaweed mixture is a quality grade that is judged based on criteria (color tone, gloss, aroma, taste, etc.) judged by experts involved in the production of seaweed products such as inspectors for dry laver appraisal. It is an optical measurement of the content of components that correlate with quality such as aroma components and taste components such as alanine, glycine, isofluorideside, sodium glutamate, inosinic acid, guanylic acid, etc. Based on the evaluation value, the concentration control of this nori preparation and / or the cutting form of the nori seaweed in the laver cutting machine and / or the ripening state of the original alga in the nori ripening machine and It is possible to control the conditions of the production process of the seaweed product, such as control of the drying state in the seaweed dryer.

  Two, three, four, or five optical means may be used for detecting the amount of transmitted light.

  The amount of transmitted light may be detected by optical means, and the amount of light from the light source may be measured to determine the light transmittance or absorbance, and a ratio calculation may be performed using the light transmittance or absorbance.

In addition to the light emitting diode, as a light source, there is light having a specific wavelength extracted from white light by a color separation prism, a filter, or the like. The light source can be selected according to the design.
As a wavelength region not affected by the quality of the seaweed, a light region of 420 nm, a light region of 700 nm, and a light region of 840 nm can be considered, and an infrared LED is used as a light source. As an infrared LED, there is an LED having a peak wavelength of 980 nm or 1300 nm. However, the peak wavelength is not limited to these values.

  Use of a photodiode, a silicon photodiode, a Cds cell, or the like is conceivable as a light receiving element forming the light receiving portion.

  The other Example regarding the display board for quality judgment of the seaweed liquid mixture of this invention is shown.

  The display panel determines the quality of the laver mixed liquid that includes a light source switch for a plurality of light sources and an optical means switch that includes a plurality of light receiving switches for each light receiving unit facing the light sources. It is good also as a display board for quality judgment of the seaweed liquid mixture used for a method.

  In addition, the display unit is a voltage value obtained by converting the transmitted light amount sensed by the light receiving unit into an electrical signal, an average value (measured average value) of a predetermined number of voltage values (transmitted light amount), a ratio calculation result (measurement result), and a reference value (Empirically determined quality criteria) can be displayed. In the display unit, in addition to displaying the graphs in different colors, the line types of the graphs may be changed, or each graph may be displayed on a separate display screen.

  Moreover, you may provide an automatic button, a manual button, a water supply button, and a drain button which control supply of a laver mixed liquid.

  Further, a setting switch for the display portion may be provided. Examples of setting switches include a detailed setting button, an error history button, and a graph button.

  Moreover, the Example based on another example test is shown below. The optical transmission spectrum of the laver mixture was measured for laver with different collection times. An example of the measurement result is shown in Table 5.

Table 5 Results of optical transmission spectrum measurement of the laver mixture In the above transmission spectrum analysis, multiple characteristic wavelengths depending on the laver pigment are selected from the obtained data, and the principal component analysis is performed for the transmittance. It was. Wavelengths of 850, 672, 648, 588, 568, 516, 496, 472, and 420 nm were selected. Table 6 shows the results.
