Abstract

The invention discloses a nondestructive testing method for the gelatin quality of a preserved egg based on a vibration technology, and relates to the field of nondestructive testing of the gelatin quality of the preserved egg. The method comprises the following steps: firstly, constructing a knock acquisition system, putting the preserved egg on a preserved egg fixing platform, bonding one end ofa piezoelectric acceleration sensor with the bottom of the preserved egg and connecting the other end of the piezoelectric acceleration sensor with a dynamic signal acquisition instrument; secondly,pressing a key on a singlechip control board to control a direct current electromagnet to achieve knock on the preserved egg; thirdly, transmitting a preserved egg vibration signal acquired by the dynamic signal acquisition instrument to a computer and processing through signal processing software; and fourthly, extracting corresponding characteristic values for modeling and selecting an optimal model for discriminating. According to the nondestructive testing method disclosed by the invention, the gelatin quality of the preserved egg can be accurately predicted by utilizing a knock vibrationtechnology; the nondestructive testing method has the characteristics of high speed, non-destructive property, intelligentization and the like, realizes the nondestructive testing of the gelatin quality of the preserved egg and has a broad application prospect.

Description

technical field [0001] The invention relates to the field of nondestructive testing of the quality of preserved egg gel, in particular to a nondestructive testing method for the quality of preserved egg gel based on vibration technology. Background technique [0002] Preserved eggs, as an original egg processing product in my country, occupy an important position in China's egg industry; they have a unique taste, high nutritional value, and have the effects of cooling appetizers, relieving heat and reducing fire; they are used in preserved egg tofu, preserved egg salad and fried preserved eggs. It is very popular in dishes and is deeply loved by consumers. Good preserved eggs look crystal clear, fragrant and have a certain degree of elasticity after removing their shells; while bad preserved eggs will have a pungent smell of sticky or liquid after removing their shells; therefore, the quality of preserved eggs not only affects their commercial value, but also And it will ser...
