Description

technical field [0001] The invention relates to a microbial reaction device, in particular to a microbial solid-state seed production and fermentation device. Background technique [0002] Microbial fermentation technology is a technology that uses certain characteristics of microorganisms to carry out industrial-scale production through modern engineering technology. It mainly includes the selection of industrial production bacteria, the control and optimization of fermentation conditions, the design of fermentation tanks and the separation of products. , extraction and refining processes. The general fermentation process divides the fermentation methods into two categories: solid-state fermentation and liquid-state fermentation according to the different physical properties of the medium. However, the active ingredients of the products obtained from liquid-state fermentation are less than those of solid-state fermentation, and solid-state fermentation technology has been d...

Problems solved by technology

[0003] Today, microbial seed production technology has a large number of spore powders, which leads to production difficulties and seriously restricts the industrialization and industrial application of microbial engineering technology.

Most of the solid-state fermentation equipment in the prior art focuses on a certain process of microbial fermentation, such as the combination of air filtration and fermentation, fermentation and inoculation, with single functions and cannot integrate multi-functional and intensive technologies, resulting in Long production time, low production efficiency and high rate of bacterial infection

[0004] CN 101974409B disclosed a bacterial culture fermentation tank device and its fermentation process on May 1, 2013. The top of the fermentation tank is provided with cleaning and disinfection injection pipes, feeding pipes and air input pipes. The fermentation tank has a PLC controller, and its input The end is connected with the temperature sensor, pH value sensor, dissolved oxygen value sensor and stirring speed sensor arranged in the tank body. The lower side of the fermentation tank body is provided with a discharge pipe, a cleaning and disinfection pipe, a pure steam input pipe, an injection water input pipe, The acid-base washing solution input pipe, the purified water input pipe and the domestic drinking water input pipe are connected, and the pure steam input pipe is bypassed to the air intake pipe provided with an air filter. However, this invention is a liquid fermentation device and cannot achieve solid fermentation. Fermentation, the function is relatively simple

[0005] CN 102443535B disclosed a solid-state fermentation bioreactor on May 1, 2013. The reactor includes a reaction box, and a porous material layer partition is arranged in the middle of the reaction box, and the reaction box is divided into upper fermentation The reactor also includes a fermentation control system, which is used to control the stirring unit, temperature control unit, humidity control unit, air supply control unit and fermentation tail gas detection and processing unit to ensure temperature, humidity, Ventilation, stirring and tail gas real-time monitoring and control, this invention can only carry out the fermentation process, and needs to be inoculated, dried and crushed in other equipment, resulting in long production time

[0006] Both of the above two technical solutions have the problem of manual feeding and retrieving, low degree of automation, high infection rate of bacteria, and the inlet and outlet are set on the top or bottom of the fermentation tank, making it difficult to observe the operation situation
