Near-infrared spectroscopy is one of the most rapid development techniques in recent years. It belongs to a physical testing technology. It has the advantages of fast, lossless, multi-component simultaneous analysis, no pollution in the analysis process, and high reproducibility of analysis results. It has penetrated all walks of life and has become an important tool in modern analytical testing technology. The near-infrared region has a wavelength range of 780 nm to 2526 nm (12820 to 3959 cm-1), which is generated by the transition of molecular vibration from the ground state to the high energy level. The main record is the hydrogen-containing group XH (X=C, N). , O) Vibration frequency doubling and combined frequency absorption, very suitable for the determination of the composition and properties of hydrocarbon organic matter.
The Chinese liquor industry is an important industrial sector in the Chinese food industry, and its annual output is huge. Based on the characteristics of near-infrared analysis technology, such as fast analysis and accurate and stable results, near-infrared spectroscopy has been gradually applied in the control of liquor production and product quality. As early as 2006, Hetao Wine Industry Urad Technology Co., Ltd. has applied near-infrared spectroscopy technology to the detection of wine cellar ingredients such as water, starch, sugar and total acid. The effect is good, the instrument operation is simple, the analysis speed is fast, and the test results are accurate and stable. The sample preparation amount is small. In view of this, this subject applies near-infrared spectroscopy technology to the detection of liquor wine, analyzes the near-infrared spectrum of liquor samples, optimizes the influence of different spectral pre-processing methods on the modeling effect, and The selection of parameters is optimized, and the model is continuously optimized to establish a calibration model for the alcohol content, total acid, ethyl hexanoate, ethyl acetate, ethyl lactate and ethyl butyrate of liquor, and to develop an efficient, fast and accurate one. The set of analysis methods provides a guarantee for determining the quality level of the original wine storage.
Greenhouse Automatic Proportional Pump
Fertilizer pump mounted directly on the pipe, the kinetic energy of pipe flow to drives the pump to work at a set ratio to suck high erconcentration drug or quantitative fertilizer in to the pump. After mixed with the water and delivered to downstream. No matter How to change the water pressure, Drug or fertilizer will be mixed and discharged according to a certain proportion.
