Problems solved by technology

The disadvantage is that a fermentation process often lasts for several days or even dozens of days, and the gas sensor will be "paralyzed" or even "poisoned" when exposed to exhaust gas for a long time; the ambient air at the fermentation site is often unclean; the ambient temperature and humidity are changing

Abstract

The invention discloses a multichannel integrated olfactory analog instrument and an on-line analysis method for a biological fermentation process. The characteristic I is that a gas sensor array, a gas sensor array constant-temperature working chamber of the gas sensor array, a multichannel fermentation tail gas precision automatic sample injection system and a computer control and analysis system are integrated in a test box. The characteristic II is that a plurality of two-position two-way electromagnetic valves realize automatic switching among multiple paths of fermentation tail gas, among the fermentation tail gas, clean air and environment air as well as between the 6,000ml / m flow and the 500ml / m flow. The characteristic III is that five biological fermentation processes, namely five fermentation tanks, can be detected and analyzed at the same time on line. The characteristic IV is that a precision throttling valve and a pressure stabilization valve are arranged in the olfactory analog instrument and realize the pressure stabilization capacity and the flow stabilization capacity of gas. The characteristic V is that the olfactory analog instrument and a plurality of fermentation tanks are plug-and-play and are simple and convenient to operate. Therefore, multiple biological fermentation processes realize automation, networking and visualization of the detection and analysis processes.

Description

technical field [0001] The present invention—a multi-channel olfactory simulation instrument and an online analysis method for biological fermentation process—relates to the fields of computer, precision measurement, automatic control, precision machinery, biological fermentation, bioreactor, analytical chemistry, and applied mathematics, and mainly solves the integration of olfactory simulation instruments Miniaturization and automation, online detection of multi-organism fermentation process, remote visualization and online analysis. Background technique [0002] The purpose of online detection, control and optimization of biological fermentation process is to obtain high value-added products in a more economical way. The influencing factors of the biological fermentation process are intricate, and it is a nonlinear stochastic process. Dissolved oxygen (DO) concentration, pH value, ventilation rate, temperature and fermentation tail gas composition and concentration (such...
