Intelligent device for quickly identifying age of Chinese rice wine based on near infrared spectrum

Abstract

The invention discloses an intelligent identification device of yellow rice wine age based on near-infrared spectra, which is characterized by the following: placing the photoelectric sensor and detecting platform with detecting clamp in the incubator; setting the light source and filter piece of near-infrared luminescent diode on the left side of detecting clamp at the neck position; placing the optical lens at the right side of detecting clamp; opposing the exit face of optical lens to the receiving face of optical fiber; connecting the exit end of optical fiber with the input end of photoelectric senor; setting the exit face of filter piece to oppose the receiving face of optical lens at the same axle through the detecting clamp; loading the temperature sensor and workpiece detector on the side of detecting clamp from the bottom of optical lens sequently. The invention solves the problem of inaccurate wine age identification result when the light splitter rotates in different temperature conditions.

Description

technical field [0001] The invention relates to an analysis technique for quickly identifying the age of rice wine, in particular to an intelligent device for rapidly identifying the age of rice wine based on near-infrared spectroscopy. Background technique [0002] In the past 10 years, the analysis of wine age and brewing year has received more and more attention. Sensory identification is an important means to identify the age of wine, but the accuracy of its determination is affected by many factors such as emotional factors, emotional factors, basic quality, physical health, and tasting environment, and it is a qualitative analysis. In order to obtain a more objective test method, some studies have been carried out at home and abroad: [0003] Chemical analysis method: mainly using modern instrument analysis techniques such as high performance liquid chromatography, gas chromatography, mass spectrometry or capillary electrophoresis combined with multivariate statistica...

AI Technical Summary

Problems solved by technology

[0006] However, the existing instruments used for this type of analysis have common disadvantages: complex process of making test samples, expensive production equipment, long analysis cycle, high cost, low efficiency, and not suitable for on-site detection and analysis

[0010] At present, there is no application of near-infrared spectroscopy analysis technology in the detection of rice wine age, and there is no report on the rapid identification device of rice wine wine age based on near-infrared spectroscopy analysis technology
