Abstract

The invention discloses a device and a method for detecting the quality of yellow wine. The method comprises the following steps: dividing qualified yellow wine into m yellow wine samples, detecting each sample sequentially by using a sensor array to obtain m signal to noise ratio characteristic value noise widths and defining the average value of the signal to noise ratio characteristic value noise widths as a threshold value Thr; detecting a yellow wine sample W to be detected to obtain the signal to noise ratio characteristic value noise width sigma of the yellow wine sample W; calculating a dynamic sorting parameter delta of the yellow wine sample W by using a non-linear self-calibration dynamic sorting model; judging whether the yellow wine sample W is qualified or unqualified by using a computer. The device and the method have the characteristics that a sensor response signal with great error can be effectively eliminated; the quality of the yellow wine can be detected accurately; and reliable data support is provided for manufacturers to produce yellow wine having stable quality.

Description

technical field [0001] The invention relates to the technical field of wine quality detection, in particular to a rice wine quality detection device and a detection method that can accurately detect the quality of rice wine and provide reliable data support for manufacturers to produce rice wine with stable quality. Background technique [0002] Shaoxing rice wine is brewed with refined white glutinous rice and Jianhu water. The alcohol concentration is about 14-18 degrees. It is often used as seasoning or drunk directly. According to its brewing method, it can be divided into Shanniang wine, Jiafan wine, Shanniang wine and sealed cylinder wine (also known as "Xiangxue wine" in Shaoxing area). [0003] With the improvement of living standards, consumers' requirements for rice wine products are also constantly changing. Factors such as the color, quality, and taste of rice wine directly affect consumers' purchases. At present, the inspection of rice wine generally adopts the...
