| Abstract: | The ethanol concentration is an important control parameter in fermentation process,the accuracy of measurement of ethanol concentration has a direct influence on the control accuracy of the fermentation process and the quality of the fermented product.Basing on the principle of gas-liquid phase equilibrium,establish the on line measurement mathematical model of ethanol concentration.The AVR and TGS2620 as the core,design an on line ethanol concentration detector;Theory and experiment prove that this detector possesses some good features including good generality,high measuring accuracy,stable performance and fast response speed and so on. |
