Online Greenhouse Gas Monitoring Equipment Construction and Application for Fermentation of Baijiu
An integrated gas condensation and dehumidification system and infrared gas sensor detection system,combined with an intelligent cloud control platform,were used to build a set of equipment that can realize the dynamic monitoring of carbon dioxide and methane concentrations in a complete fermentation cycle.The equipment operates stably in the high temperature and high humidity environment of the cellar,and the data transmission is timely and accurate;during the fermentation cycle,the carbon dioxide reaches a peak value of 38.05%vol on the 11th day of fermentation,and then decreases and stabilizes at about 2%vol;the methane content rises slowly,and reaches a peak value of 39.92%vol on the 127th day of fermentation;the results of the present research provide an opportunity to control the greenhouse gases in solid-state fermentation of Baijiu and to realize energy saving by rationally utilizing fermentation waste gases.The results of this study provide data support for the effective control of greenhouse gases in solid-state fermentation of Baijiu and the rational use of fermentation waste gas to achieve energy saving and emission reduction.
