Embodiment 1

[0052] refer to figure 1 , make a multifunctional solid-state fermentation reactor of the present invention. The pressure control module 15 used in this embodiment is a pressure liquid level transmitter purchased on the market (Kunlun Coastal Sensing Technology Center, outputting 4-20mA standard signal), and the data is sent to the control center. The first gas analysis module 21-1 and the second gas analysis module 21-2 are composed of intelligent oxygen probe and gas transmitter (Shanghai Shengtaike Instrument Co., Ltd.), common temperature and humidity probe and transmitter, eSENSE-K type CO2 It consists of a probe and a transmitter, which can be realized by professional technicians, and the collected data is sent to the control center. The speed-regulating air pump 22 is an XGB18-130B type air pump. Both the first heat exchanger 25-1 and the second heat exchanger 25-2 are stainless steel gas buffer tanks with coiled tubes, the gas goes outside the coiled tubes, and the h...

Abstract

The invention relates to a multifunctional solid state fermentation reactor. The reactor comprises a main tank, an auxiliary system and a control center, wherein a tank cover is fixed at the upper port of the main tank through a flange; a cylinder port is fixed on the top of the tank cover; the upper end face of the cylinder port is provided with four ports; pipelines connected with the four ports are connected with a gas purification module, a pressure meter and a gas analysis module through valves; the tail end of the pipeline of a first port is connected with a four-way pipe; and one port of the four-way pipe is connected with the main tank through a gas pipeline, and the formed gas forms a loop from a fourth port to a fifth port; and the auxiliary system consists of an aseptic inoculation part, a circulating gas part and a foreign gas part. The reactor can realize a closed solid state fermentation process without mixed bacterial pollution or pressure pulsation, can be applied to the process of quickly decomposing solid organic matters, and can monitor various parameters in the fermentation process, and a method for extracting a required fermentation product in the reactor in situ is provided.

Description

technical field [0001] The invention relates to a solid-state fermentation device, in particular to a multi-functional solid-state fermentation reactor. Background technique [0002] Compared with solid-state fermentation, liquid fermentation has certain advantages in material transportation and control of fermentation conditions. The successful industrial production of penicillin almost makes liquid submerged fermentation technology represent the entire fermentation industry. However, since the 1990s, resource and energy crises and environmental problems have become prominent, and solid-state fermentation technology has aroused great interest due to its unique advantages. The main advantages of solid-state fermentation are: ①The medium is simple and widely sourced, mostly cheap natural substrates or industrial and agricultural waste; ②Low investment, low energy consumption; ③High yield, simple extraction process; ④No "three wastes" "Emissions, etc. [0003] Solid-state fe...
