Conventional egg quality control methods are largely based on internal and external quality standards. The external quality is determined by visual inspection based on the degree of contamination and the strength of the egg shell, and the internal quality is indexed by Haugh unit (hereinafter referred to as HU) method considering egg weight and egg weight by harlaning (breaking) the egg. . HU freshness measurement method is widely used in egg grading system and commercial use, and because eggs are broken and judged one by one, there are also limitations on the place limit and the number of surveys that need to be carried out at a certain place where the research equipment is installed.

In addition, the low freshness in the distribution process of eggs is also difficult to determine the current situation.

In addition, since freshness cannot be determined by destroying a myriad of eggs corresponding to a group one by one, freshness is determined by destroying only a small number corresponding to a sample value, and accordingly, the freshness of the entire group is determined only by the sample value. For this reason, there is a problem that the reliability of freshness evaluation and determination is inferior.

In addition, despite the deterioration of freshness depending on the storage condition and environment during distribution, it is difficult to determine the freshness of the state, there is a problem that does not evaluate and determine the freshness at all.

As shown in FIG. 1, the non-destructive egg freshness measuring system has a main body 1 housing the spectroscopic and detection unit 13, the data processing and collection unit 15, and an upper end of one side of the main body 1. The monitor type display unit 17 which is located at and informs the user of the data processing result is provided.

The spectroscopic and detection unit 13 receives the infrared light collected from the egg, converts the infrared light into an electrical signal that can be recognized by the system, and outputs the data to measure and judge the egg. The output data is processed and collected. The grade of the freshness of the egg is determined by converting it into the egg spectral data received by the unit 15. When the determination is made in this way, the display unit 17 informs the result of the determination in letters, numbers, and languages that the user can recognize.

As shown in FIG. 2, the light-emitting and light-receiving units 10 and 11 which provide infrared light to the spectroscopic and detection unit 13 are located in a predetermined region of the egg transfer unit 19 for transporting eggs one by one. It is fixed to the support stand 3 and the mounting stand 5. The infrared light source emitted from the light emitting unit 10 toward the egg is diffused into the egg and reflected by the light receiving unit 11. At this time, the direction of the light emission and the light reception is composed of a three-dimensional angle of 90 degrees or less that can receive infrared light from the egg of the reflected portion, preferably the freshness of the egg has been determined between 40 degrees to 90 degrees Has the highest reliability.

In addition, as shown in FIG. 3, another embodiment of the light emitting and receiving portions 10 and 11 has a structure similar to the above reflection type, except that an infrared light source in which the directions of the light emitting and receiving light are transmitted are transmitted. It is composed of a solid angle of 90 degrees or more that can receive light, and preferably has the highest freshness of the egg whose solid angle is determined between 170 and 190 degrees.

Then, a power supply unit 23 for supplying power for operating this is provided.

The light-emitting and light-receiving units 10 and 11 operate simultaneously with each other to generate an infrared light source toward the egg, and collect the infrared light from which the infrared light source appears as either diffused, reflected or transmitted from the egg. When the infrared light source is irradiated toward the egg from the light emitting unit 10, the infrared light unit diffuses or reflects on the contents (sample) of the inside of the egg is collected by the light receiving unit 11. In addition, depending on the structure, the light receiving unit 11 may collect the light passing through the egg by the infrared light source irradiated from the light emitting unit 10.

By using the constructed model, each individual egg is analyzed on a daily basis, and through the daily analysis, the freshness value of the egg (hereinafter referred to as “grade”) can be represented.

Such a model was measured using 23 samples of eggs from 60 HU to 90 HU, and then measured with freshness. The measured results showed that the error of calibration (SEC, Standard error), which is the predictive performance of each model, was measured. of calibration) and standard error of prediction (SEP) and correlation coefficient (R) (SEC and SEP are minimal and correlation coefficient (R) close to 1 maintains good correlation) SEC Is 3.23, SEP is 5.27 and correlation coefficient (R) is 0.81.

The display unit 17 visually displays at least one of the freshness grade determined by the data processing and collection unit 15 and the egg spectrum of the detection unit.

The eggs thus transferred receive the infrared light source by the light emitting unit 10 to diffuse and reflect the light source. Then, it is determined whether the light receiving unit 11 receives the infrared light diffused and reflected, and the second step is repeatedly performed until the infrared light is detected by the light receiving unit 11 (S3).

When the infrared light diffused and reflected by the light receiving unit 11 is received, the spectroscopic and detection unit 13 converts the egg spectrum data into an electrical signal and outputs it to the data processing and collection unit 15 (S4).

Then, the data processing and collection unit 15 determines the grade of the egg freshness using the partial least squares regression (PLSR) and routine analysis values using the egg spectrum data. In other words, the correlation between the spectral data of the egg and the HU of the egg is first data-processed using the partial least squares regression (PLSR) method (S5), and the correlation system produced by the partial least squares regression curve. After inserting the data, modeling is made with the correlation data (S7), and the daily analysis is performed for each individual egg by the constructed model, and the freshness value of the egg (hereinafter, "grade") is analyzed through the daily analysis. (S8).

Such a model was measured using 23 samples of eggs from 60 HU to 90 HU, and then measured with freshness. The measured results showed that the error of calibration (SEC, Standard error), which is the predictive performance of each model, was measured. of calibration) and standard error of prediction (SEP) and correlation coefficient (R) (SEC and SEP are minimal and correlation coefficient (R) close to 1 maintains good correlation) SEC Is 3.23, SEP is 5.27 and correlation coefficient (R) is 0.81.

The freshness grade and egg spectrum data of the egg are displayed on the display unit 17 so that the administrator and the user can recognize them (S9).
