Abstract

The invention discloses a baijiu impurity spectral diffraction visual identification device and method, and belongs to the technical field of baijiu impurity detection. At present, an impurity detection method used by domestic baijiu manufacturers is a manual lamp detection method, the efficiency is low, workers work in a high-brightness and high-noise environment for a long time, great harm is caused to body health, the labor cost is increased, the baijiu impurity detection method based on image processing is low in detection cost, but the detection precision is not ideal. The invention provides a spectral diffraction visual identification device and method for baijiu impurities. After the modulated laser passes through the wine bottle to be detected, the generated diffraction image completes detection of baijiu impurities by utilizing an image processing technology, single-point measurement of fine objects is realized, the measurement is convenient and visual, the adaptability is high, filament impurity detection and particle impurity detection can be realized, a detected object is not damaged in the detection process, and the detection efficiency is high.

Description

technical field [0001] The invention relates to the technical field of liquor impurity detection, more specifically, it relates to a device and method for visual recognition of liquor impurities by Guan Gong diffraction. Background technique [0002] In the process of liquor canning, foreign impurities may be introduced due to incomplete filtration and bottle brushing, and substandard sanitation of workshops and personnel. Once liquor containing impurities enters the market, it is very easy to cause consumer complaints and even cause health and safety problems. Therefore, liquor The on-line detection of impurities in the medium is very meaningful. At present, the impurity detection method used by domestic liquor manufacturers is the artificial light inspection method. This method refers to that workers face the light source on the production line and inspect liquor bottles bottle by bottle with the naked eye. This method is inefficient, and workers work in a high-brightness...
