Alcohol concentration measurement device and alcohol concentration measurement method for closed container

Abstract

The invention discloses an alcohol concentration measurement device and an alcohol concentration measurement method for a closed container. A probe is mounted on the side wall of a shell and is used for implementing laser motivation and receiving aiming at the closed container containing an alcohol solution sample. An embedded system circuit board card module controls a laser source through a laser power control module so as to emit laser to the probe, the laser is scattered by virtue of an alcohol solution in the closed container and is received by the probe, a scattered light receiving signal is extracted by Raman signals collection module to obtain a Raman spectrum data, the Raman spectrum data is sent to the embedded system circuit board card module, and then the embedded system circuit board card module processes the Raman spectrum data to distinguish a spectrum characteristic peak numerical value and calculates the alcohol concentration. The alcohol concentration measurement device is small in volume, simple and convenient to operate and lossless and rapid to detect, a detection sample does not need to be preprocessed, and a closed wine bottle can be directly detected without being opened, so that the complex operations of a traditional pycnometer method and a traditional alcohol meter method are solved; and furthermore, the application object is wide, and the alcohol concentration measurement device has relatively high field application values.

Description

technical field [0001] The invention belongs to the detection field, and in particular relates to an alcohol concentration measuring device and a measuring method for a closed container. Background technique [0002] Alcohol is widely used in chemical industry, metallurgy, papermaking, printing, brewing, food, sugar industry and environmental protection industry. Alcohol concentration is one of the main indicators of the quality of liquor and industrial alcohol production. Measured according to national standards. Liquor samples must be distilled, constant volume, and then the alcohol concentration is measured by the pycnometer method or the alcohol meter method. The above-mentioned various methods are time-consuming and the process is cumbersome. Using device analysis methods, such as using gas chromatography to analyze ethanol content in liquor, not only the operation process is complicated, but also the device is expensive, making it difficult to quickly detect the alco...
