Raman spectrum-based online detection device for yeast activity of wine brewing fermentation liquor

Abstract

The invention relating to the technical field of wine brewing discloses a Raman-spectrum-based online detection device for the activity of saccharomyces cerevisiae in a fermentation broth, thereby solving a problem that a Raman spectrum detection device in the prior art is low in detection accuracy. The device is characterized by comprising a a first water pump which is connected with a three-wayvalve through a water pipe; the three-way valve is connected to a detection box through a water pipe; the detection box is arranged on a spectrum detection device; a filtering device for filtering wine is further arranged between the first water pump and the three-way valve; the three-way valve is further connected with a second water pump; the second water pump is connected to a clean water poolthrough a water pipe; the three-way valve is an electromagnetic valve, and the three-way valve intermittently opens channels between the filtering device, the second water pump and the detection box.According to the invention, the accuracy of measurement results can be improved.

Description

technical field [0001] The invention relates to the technical field of brewing, in particular to a Raman spectrum-based online detection device for yeast vigor in brewing fermentation broth. Background technique [0002] Fermentation is one of the most important and critical links in the winemaking process. The quality of the yeast in the fermentation broth is directly related to the yield and quality of its fermentation products. The quality of yeast is generally evaluated by activity and vitality. Activity refers to the viability of cells, and yeast activity refers to the physiological state of yeast cells, which can also be understood as the adaptability and metabolic ability of living cells to the environment. Yeast activity is an important factor affecting fermentation performance and taste. Only stable and high-activity yeast can brew high-quality wine. Therefore, how to realize the on-line detection of yeast vigor in fermentation broth has always been the focus of co...
