Abstract

The invention discloses a portable electronic nose system for monitoring the state of a tremella aurantialba fermentation process in real time, and belongs to the field of real-time monitoring of theproduction process. The system comprises an air purifying device, a fermentation tail gas dehydrating device, a solenoid valve A, a solenoid valve B, a gas passage tee, a gas flow meter, an adjustablevacuum pump, a gas reaction chamber, a sensor array, a temperature and humidity sensor, a signal conditioning circuit, a microprocessor, and a host computer. A control module and a pattern recognition module are provided in the host computer. The control module controls the microprocessor through a LabVIEW host computer to perform gas flow value, sensor reduction, fermentation tail gas collection, gas reaction room temperature humidity monitoring, and data transmission. The pattern recognition module is configured to analyze and process the signal input by the control module to determine thefermentation state of the tremella aurantialba fermentation broth. The monitoring system of the invention not only has simple operation but also can accurately and timely monitor the gas generated during the fermentation process of the tremella aurantialba.

Description

technical field [0001] The invention relates to a detection instrument for the state of the fermentation process, in particular to a portable electronic nose system for monitoring the state of the fermentation process of golden ear, which belongs to the field of real-time monitoring of the production process. Background technique [0002] The fermentation process is an important industrial production method, which is widely used in the production of high value-added products such as biopharmaceuticals, fine chemicals, and deep processing of agricultural products. The fermentation process not only has the characteristics of time-varying, large inertia, and uncertainty of general nonlinear systems, but also some important parameters in the fermentation process, such as bacterial concentration and product concentration, cannot be measured online, so the control ratio of the fermentation process is Generally nonlinear systems are more complex. Due to the complex mechanism of th...
