Embodiment 1

[0038] Such as figure 1 As shown, the detection device for quickly identifying the grade of tea leaves in this embodiment includes: a sample pool 1 for accommodating the tea soup of tea samples to be tested, an LED light-emitting lighting source located on one side of the sample pool 1, and an LED light source located on the other side of the sample pool 1. detection element on one side. Specifically, the sample cell 1 is made of quartz.

[0039] The light source includes LED ultraviolet light source 2 and LED white light source 3. Specifically, the wavelength of LED ultraviolet light source 2 is 280nm. The catechin in tea has a maximum absorption peak at 280nm, and the content of catechin can be judged by the light absorption value at 280nm. . During detection, the LED ultraviolet light source 2 with a wavelength of 280nm can be directly turned on for the detection of tea infusion. LED white light source 3 provides stable illumination light for measuring the color differen...

Abstract

The invention discloses a detection device for rapidly identifying the grade of tea leaves, and belongs to the technical field of tea leaf detection equipment. The detection device comprises a sample pool used for containing tea sample tea soup to be detected, an ultraviolet light source and a white light source arranged on one side of the sample pool, and a detection element arranged on the other side of the sample pool, and a photoelectric converter is arranged on an ultraviolet light emergent light path and used for receiving ultraviolet light emergent light signals, and converting the ultraviolet light emergent light signals into electric signals and transmitting the electric signals to a processor. A color sensor is arranged on a white light emergent light path and is used for receiving white light emergent light signals, collecting red, green and blue color signals and transmitting the red, green and blue color signals to the processor; and the processor receives and processes the ultraviolet signal and the color signal, runs built-in grade distinguishing model software, and outputs a grade label corresponding to the tea sample to be detected. The ultraviolet light path and the white light path are arranged to detect samples in the same sample cell at the same time, and multi-dimensional data are obtained through one-time operation; meanwhile, instrument elements are simplified, debugging is not needed before use, and operation is easy.

Description

technical field [0001] The invention relates to the technical field of tea detection equipment, in particular to a detection device for quickly identifying tea grades based on color difference and ultraviolet spectrum technology. Background technique [0002] As one of the world's three major non-alcoholic beverages, tea is widely loved by consumers. For a long time, the identification of tea quality has been dominated by manual evaluation, mainly using the artificial sensory evaluation method to evaluate the color, aroma, taste and shape of tea. However, manual review has high professional requirements, ordinary consumers cannot reach the review level, and the results are easily affected by subjective factors and objective environments, making it difficult to promote in daily life. With the in-depth research and development of intelligent testing instruments in the field of food quality identification, the quality identification of tea is becoming more and more convenient....
