A method and device for rapid detection of tea soup color

Abstract

The invention discloses a method and a device for rapidly detecting liquor color of tea water. The device comprises a purple laser gun, a square transparent container, a light attenuation detector, a signal amplification circuit, a microcomputer and a display screen, wherein the tea water to be tested is contained in the square transparent container, one side of the square transparent container is provided with the purple laser gun, the other side of the square transparent container is provided with the light attenuation detector, light axes of the purple laser gun and the light attenuation detector penetrate through the center of a vertical face of the square transparent container, the purple laser gun emits purple laser with constant strength, the light attenuation detector detects the degree of attenuation of the purple laser and outputs the detection result to a signal amplifier and then to the microcomputer, the microcomputer calculates the concentrate and the color of the tea water to be tested, and the display screen displays the calculation result. With the method and the device, the liquor color of the tea water made by a tea making machine can be detected immediately, and specific numerical values can be rapidly obtained and are used for providing the technical base for regulating technological parameters for making tea by the tea making machine, so that the tea making is scientific and operable; compared with a detecting mode with a chromometer, the device and the method provided by the invention have the advantages that quantitative evaluation can be carried out on the liquor color of the tea water rapidly, and on-site immediate detection is facilitated.

Description

technical field [0001] The invention belongs to the technical field of tea detection. Background technique [0002] A good cup of brewed tea should not only have an elegant and long-lasting aroma, a mellow and sweet taste, but also a clear and bright tea soup and the unique color of this tea. People who often drink tea will smell its fragrance, observe its color, and taste its taste when tasting tea. The color of tea soup can give people a kind of beautiful enjoyment visually. Therefore, the soup color of tea has always been the main indicator for people to evaluate the quality of tea and the level of tea making technology. [0003] On the one hand, the soup color of tea is related to the type of tea and the method of making tea. Different teas such as green tea, black tea, and oolong tea have different soup colors. On the other hand, the soup color of tea has a lot to do with the brewing process. In the traditional manual brewing process, the mastery of the color of the t...

Problems solved by technology

[0007] Theoretically, the color of tea soup can be measured with a colorimeter, but since the colorimeter is used, it is necessary to preheat the lamp for 5 minutes each time, select a filter that is complementary to the color of the substrate, and adjust to zero (use a blank control). Zero adjustment), sensitivity adjustment, analysis of samples and standard solutions and other preparatory work, it is also necessary to frequently measure the same solution to check the repeatability of the colorimeter, and due to the randomness of the logarithmic measurement scale unit on the instrument, even if the The sensitivity / scale on the meter is adjusted to the zero control point, the value obtained on one instrument is not directly comparable to the value measured on another instrument, nor is it directly comparable between different settings put together, these use colorimetric The meter is difficult to be used in the rapid determination of tea soup color, so it cannot be applied to the detection technology field of tea soup color in tea making machines

[0008] Although the chemical analysis method can also be used in the chemical laboratory to detect the content of the main components in the tea, and the results of the analysis can be combined with the components obtained from the multiple color measurements of the colorimeter-the soup color curve to judge the color of the brewed tea soup. However, this method takes too long and costs too much. It can only be used for detection and research, and cannot be used in the rapid determination of tea soup color, and it has not been applied to the detection technology of tea soup color in tea making machines.
