Description of the Invention: [Technical Field] The present invention provides a non-destructive detection method for the degree of gelation of preserved eggs, which is mainly applied to non-destructive detection techniques of preserved eggs. [Prior Art] Traditionally, farmers often judge the quality of their internal quality by tapping the fruit by hand, thus developing many non-destructive tests using sound waves, and their use in agriculture has become quite common. For example, using sound waves to detect the quality of watermelon, and analyzing and judging whether there is a cavity inside the watermelon according to the characteristics of the sound wave response; or using a pulse to strike the radish, exploring the relationship between the second resonance frequency and the elastic modulus, and then detecting by sound wave Come find the hollow radish. Or, tapping the surface of the duck egg shell with a sound collecting tube and taking the sound wave signal for analysis and comparison, and found that the sound waveform of the intact egg and the cracked egg has obvious difference. As for the processed preserved eggs, how to check the best finished products of preserved eggs? Some of the commonly marketed preserved eggs will still stick to the eggshells. These preserved eggs are preserved eggs that are not completely gelatinized, and the taste is not optimal. Generally, the preserved eggs can be lightly thrown into the air. When the preserved eggs fall back into the hands, they will produce a vibration like a rubber candy. This is the vibration of the protein in the eggshell after the gel. This kind of preserved egg is the condensation. Gummy finished eggs. The preserved eggs on the market are all tested by conventional artificial methods. The method is to place the preserved eggs in the palm and beat the preserved eggs with the other hand's fingers to check whether vibration is generated to determine the effect of the preserved egg enzymes. The detection of 200825409 can only rely on manual operation inspection. The shortcomings of manual detection include: long-term fingering on the preserved egg is not only a waste of manpower, but also easy to break the egg, and knocking the preserved egg with a finger for a long time can also cause finger injury. In the absence of certain standards, the choice of personal subjective experience makes the preserved eggs sold in the market still have incompletely gelled preserved eggs, which are still problems and problems that need to be overcome. \ [Summary of the Invention] The present inventors are currently engaged in the manufacture and design of related products, accumulating practical experience and experience for many years, and actively investing in the spirit of innovation and improvement in response to the existing problems and deficiencies of the traditional methods of detecting finger-beating of preserved eggs. A non-destructive test method for the degree of gelation of a finished egg. The technical means applied by the present invention to solve the problem and the effect of the prior art are as follows: firstly, the time domain map of the tapping reaction of the striking rod is directly measured by the spectrum analyzer, and the vibration characteristics are compared, and the time domain response after the product excitation is established. The logarithmic attenuation of the peak value of the signal and the energy integration of the curve to determine the decay rate and reaction energy of the logarithmic decay, and then according to the result of removing the eggshell, the attenuation rate and the standard value of the reaction energy are summarized, and the attenuation rate is lower than the standard value or the reaction energy. Those above the standard value are expressed as preserved eggs with a good gelatinization degree. If the attenuation rate is higher than the standard value or the reaction energy is lower than the standard value, it is expressed as the incompletely preserved preserved egg' as a basis for judging the quality of the preserved egg.俾 can achieve quality inspection automation, improve the accuracy of judgment, and save labor. [Embodiment] In order to make it possible for a person skilled in the art to have a good understanding of the art to have a deep understanding of the device content of the present invention and the functional benefits that can be achieved, a concrete example 5 200825409 embodiment will be listed, and the following detailed description will be given in conjunction with the drawings. : A non-destructive method for detecting the degree of gelation inside a preserved egg. Firstly, the time domain map of the knocking reaction of the percussion egg knocking the preserved egg is directly measured by a spectrum analyzer, and the vibrational characteristics of the preserved egg are compared to establish the time domain after the excitation. The logarithmic attenuation of the peak value of the response signal and the energy integration of the curve are used to determine the decay rate and reaction energy of the logarithmic decay. Then, according to the actual result of removing the eggshell, the standard value of the egg decay rate and the reaction energy is summarized. For practical applications, please refer to the first and second figures: a perspective view and a plan view of the present invention. As shown in the third figure, it is an enlarged view of the local portion of the striking mechanism of the present invention. And the fourth® is shown as the detection state of the present invention. The device is mainly provided with a transport mechanism 2 〇, a striking mechanism 30, a good scooping mechanism 40, and a defective product scooping mechanism 5 疋 on the machine 1; wherein the transport mechanism 20 is a rotating turntable 21 The turntable 21 is provided with a plurality of sockets 2 2 in an aliquot arrangement, and the preserved eggs i are placed on the sockets 2 2 smoothly. The design of the sockets 2 2 must allow the preserved eggs 1 to be freely shaken and avoid the impact force. If it is too large, it will cause an offset, which will affect the detection result. The striking mechanism 30 will be equipped with a wooden round head at the front end of the striking stick 31, so as to beat the preserved egg 1, and should avoid breaking the preserved egg i and give the preserved egg an external force impact. In the time domain and frequency domain diagram generated by the impact of external force, in order to measure the time domain signal generated when the vibrating egg 1 vibrates, the accelerometer is first connected to the spectrum analyzer, and the spectrum analyzer is connected to the personal computer. And use the software program analysis, directly capture the time domain generated by preserved egg 1 200825409 If i» and use its built-in fast-changing preserved egg 1_Nish eyes _ frequency domain sulfur 'stone and anti-R, The vibration signal will produce different degrees of attenuation: this will Export the number to the program, find the logarithmic rhyme of the eight in the time domain diagram (as shown in the fifth ®) or the curve energy: two (as shown in the sixth figure), determine the attenuation of the time domain signal and Anti-February "=»Derating rate is lower than the standard value or the reaction energy is higher than the standard value, indicating that the T vibration J is as shown in the seventh figure) 'is the preserved egg with a good gel degree, the attenuation rate is the county value or The standard value of the reaction energy commission indicates that no significant vibration has occurred (as shown in the eighth figure), and the quality of the preserved egg 1 is good or bad for the incomplete egg-preserving egg factory.捡 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良 良In summary, the present invention provides a method for non-destructive detection of the degree of gelation inside a preserved egg, which is actually completed by the inventors.
