Monitoring device and monitoring method for fermentation based on multi-frequency L-wave electromagnetic waves

Abstract

The invention discloses a multiple-frequency L-band electromagnetic wave fermentation monitoring device and a monitoring method thereof. The device includes an L-band electromagnetic wave transmitting device, an L-band electromagnetic wave receiving device, and a data processing module installed in parallel and opposite to each other in a solid-state fermentation tank , Data display module. The electromagnetic wave transmitting device is used to transmit a number of specified frequency L-band electromagnetic waves, and the data processing module is used to analyze the frequency and phase angle changes of the specified electromagnetic waves received by the electromagnetic wave receiving device after passing through the fermentation medium, and through the change amount and the measured data A regression model for solid-state fermentation process monitoring was established. The beneficial effect of the present invention is: according to the changes of frequency and phase angle when several specified frequency L-band electromagnetic waves are transmitted in the fermentation medium in different reaction periods, the experimental analysis results of the biomass in the fermentation process and the data regression model are established, so as to realize the The monitoring of the fermentation process solves the problem that existing sensors are difficult to implement and cannot be monitored online.

Description

technical field [0001] The invention relates to a fermentation monitoring device based on multiple frequency L-band electromagnetic waves and a monitoring method thereof, and belongs to the technical field of solid-state fermentation process monitoring devices and monitoring. Background technique [0002] At present, electromagnetic waves are mainly used in detection, communication, positioning, treatment and so on. According to different wavelengths, it is divided into different bands: L, S, C, X, Ku, K, Ka, U, V, W, etc. A large number of monitoring technologies based on near-infrared spectroscopy have gained attention in the field of fermentation, and the monitoring application of L-band electromagnetic waves in the field of fermentation is rare. The wavelength range of the L-band electromagnetic wave is 150mm-300mm, which can detect quickly and non-destructively, and has the advantages of strong anti-interference ability. [0003] At present, there are still many diffi...
