A real-time monitoring system and monitoring method for solid-state fermentation process status

Abstract

The invention relates to a real-time monitoring system and a real-time monitoring method for a solid fermentation process condition. The real-time monitoring system and the real-time monitoring method belong to the field of biological engineering detecting technology. The real-time monitoring system comprises an acquiring module for solid-state fermentation process parameters, an expert decision system and a feedback control module; wherein the acquiring module for the solid-state fermentation process parameters is used for acquiring key variable data in the fermentation process and transmitting the key variable data to the expert decision system. The expert decision system is used for analyzing reliability and measurement error of the data information, deciding whether the fermentation condition in a fermentation tank is normal, and transmitting decision result information to the feedback control module. The feedback control module generates a control signal according to the decision result; an executing device adjusts fermenting parameters according to the information of the control signal; and finally automatic monitoring in the solid-state fermentation process is realized. The real-time monitoring system and a real-time monitoring method have functions realizing monitoring and feedback control, settling problems such as instable quality of a solid-state fermented product and relatively large difference between different bathes of the product, and ensuring high quality in solid-state fermentation.

Description

technical field [0001] The invention relates to a real-time monitoring system and monitoring method for the state of a solid-state fermentation process, belonging to the technical field of bioengineering detection. Background technique [0002] Solid-state fermentation is the main production method in my country's brewing industry, such as liquor, vinegar, soy sauce and other fields occupy an important position. However, the production of traditional solid-state fermentation products is still in the traditional manual workshop mode in my country. The control of production technology and process parameters still mainly relies on manual experience and the detection of sampling physical and chemical indicators. The production method is generally open and relatively rough. And at present, there is a lack of online measurement technology for key parameters such as bacteria, substrate and product concentration, and it is difficult to use a suitable mathematical model to describe th...
