Device for rapidly and nondestructively detecting component content of yellow rice wine

Abstract

The invention relates to a device for rapidly and nondestructively detecting the component content of yellow rice wine. The existing detection method has the disadvantages of large time consumption, complication in operation and damage to a sample. In the device provided by the invention, after the light emitted by a light source is collimated through a lens, a modulating disk is aligned to the collimated parallel light, thereby carrying out the light intensity modulation; the collimated parallel light is split by a spectrometer which comprises an interference filter, a filter wheel and a stepper motor; the monochromatic light with the bandwidth of 10-20nm is emitted into an immersion optical fiber probe and then emitted to a detector; after the weak photoelectric signals output by the detector are amplified by an instrument amplifier and processed through a low pass filter, and the weak photoelectric signals are converted into digital signals by a converter; and the digital signals are transmitted to a digital signal processor. The device provided by the invention can be used for carrying out the nondestructive detection on conventional detection items such as the alcohol, sugar and acidity and the like in the yellow rice wine, is rapider and more friendly-environment than the conventional yellow rice wine component physicochemical check, does not need to preprocess the sample and has the advantages of good detection result repeatability and low detection cost.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection, in particular to a device for nondestructive and rapid detection of the main components (alcohol, sugar, acidity, etc.) of rice wine. Background technique [0002] At present, conventional physical and chemical component analysis has high accuracy and reliability, and can analyze various main components in the production process of rice wine, but the pretreatment and detection of rice wine samples are time-consuming and destructive to samples. It is cumbersome and complicated, and the timeliness of the analysis results obtained is poor. In recent years, near-infrared spectral analysis technology has developed rapidly in replacing conventional physical and chemical analysis due to its fast, stable, accurate, energy-saving and environmental protection (no reagent required) and low cost in terms of quality analysis. Near-infrared technology has been used in various The composition a...
