Description

Technical Field

[0001] The utility model relates to the technical field of microbial fermentation, in particular to horizontal microbial fermentation equipment. Background Art

[0002] The production process of general microbial agents includes liquid method or solid method. The solid method is mostly used for the production of filamentous fungi such as molds, and the liquid method is mostly used for the production of unicellular bacteria. For example, microorganisms such as pseudomonas (photosynthetic bacteria PSB), nitrifying bacteria, and denitrifying bacteria commonly used in sewage treatment are all produced using liquid method. When cultivating microorganisms by liquid method, the main method is to prepare a suitable culture medium according to the nutritional needs of the microorganisms, and use fermentation equipment for large-scale liquid fermentation culture. However, microorganisms are not conducive to large-scale transportation and storage in a liquid state. Therefore, after the microorganisms are propagated, they need to be added to a carrier for drying, drying, and other operations. The existing technology includes the following drying methods: for example, by spraying the fermentation liquid into droplets and transporting it to a specially set drying tower, the droplets of fermentation liquid are in contact with hot air to quickly evaporate the water, thereby forming a dry powder; for example, the fermentation liquid is transported to a drum dryer and the water is removed by the rotation of the drum to form a dry powder. The fermentation liquid drying operation in the existing technology is suitable for large-scale standardized industrial plant environments, but in medium and small-scale production environments, such drying methods are obviously not cost-effective and have poor practicality. Based on the current situation, it is of great significance to design a new type of microbial fermentation equipment to give it more functions to meet the needs of medium and small-scale production of different types of microorganisms.

The following detailed description should not be considered restrictive, and the scope of the embodiments of the present application is limited only by the claims of the published patents. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present application. Spatially related terms, such as "upper", "lower", "left", "right", "below", "below", "lower", "above", "upper", etc., may be used in the text to illustrate the relationship of one element or feature shown in the figures to another element or feature.

[0023] This application proposes a horizontal microbial fermentation equipment, see attached Figures 1 to 3 As shown, the horizontal microbial fermentation equipment mainly includes the following components: a fermentation tank 1, a heating system, a stirring device 11, an aeration pipe 2, an air compressor 3, an air heater 4, a fill light 5 and a disinfection lamp, etc.

[0024] Among them, such as Figure 2 、 3 As shown, the fermentation tank 1 is a horizontally placed cylindrical container, the inner cavity of which is used to accommodate the culture medium and microorganisms to be fermented. The material of the fermentation tank 1 is usually stainless steel or other corrosion-resistant and high-temperature resistant materials to ensure its service life in a long-term high-temperature and high-humidity environment. Specifically, the fermentation tank 1 includes a lower chamber 28 and an upper chamber cover 29. One side of the upper chamber cover 29 is flipped and connected to the lower chamber 28, and the other side is provided with a handle 30 for easy operation. A sealing strip 31 is provided at the connection between the upper chamber cover 29 and the lower chamber 28 to ensure airtightness during the fermentation process. A layer of heat-insulating shell 32 is also provided on the outside of the lower chamber 28 and the upper chamber cover 29 to help maintain a stable temperature during the fermentation process. At the same time, an observation port 24 and a feed hopper 25 are provided on the top of the upper chamber cover 29. The observation port 24 facilitates the operator to observe the status of the fermentation process, and the feed hopper 25 is convenient for feeding. The bottom of the lower chamber 28 is supported and fixed by multiple legs, and a discharge port 26 is provided at the bottom of the lower chamber 28. A switch valve 27 is provided at the discharge port 26 to facilitate the removal of the fermentation product after the fermentation is completed.

[0025] Aeration tube 2 is arranged at the bottom of fermenter 1 along the axial direction of fermenter 1. Its primary function is to supply oxygen to the culture medium within fermenter 1 to meet the microorganisms' aerobic needs. Aeration tube 2 includes an air supply end connected by a pipe to air compressor 3. Aeration tube 2 utilizes a nanoporous design, allowing compressed air to be evenly distributed into the culture medium through nanoscale pores, forming extremely fine bubbles. The nanoscale pores produce extremely small bubbles, increasing their specific surface area, significantly improving the efficiency of oxygen dissolution in the culture medium. Because the bubbles are smaller and more evenly distributed, they help maintain a consistent dissolved oxygen level throughout fermenter 1, preventing localized excessive or insufficient oxygen concentrations. Air compressor 3 generates and supplies compressed air, which is piped to aeration tube 2. The compressed air is evenly distributed into the culture medium through aeration tube 2, forming fine bubbles, thereby increasing the dissolved oxygen content in the culture medium and promoting microbial metabolism and growth. The output pressure and flow rate of air compressor 3 can be adjusted to suit the needs of different fermentation processes. An air heater 4 is installed between the aeration tube 2 and the air compressor 3. A third temperature sensor 33 is installed on the air heater 4 to monitor the air temperature. The heated air passes through the nanoporous aeration tube 2 and enters the fermentation tank 1, drying the fermented material inside. The air heater 4 uses a high-efficiency heating element that quickly and evenly heats the air, ensuring a constant temperature output.

[0026] To further optimize the fermentation environment, a supplemental light 5 and / or a disinfection light are installed on the top of the fermentation tank 1. The supplemental light 5 provides illumination, particularly for microorganisms that require light, such as certain photosynthetic bacteria, to promote their growth and metabolism. The disinfection light is used for sterilization before and after fermentation, preventing contamination by foreign microorganisms and ensuring a pure and stable fermentation process. The supplemental light 5 and the disinfection light can be independently controlled as needed to achieve optimal fermentation results.

[0027] Furthermore, the heating system includes a circulation flow path 7 provided inside the side wall of the fermentation tank 1. A circulation pump 8, a water heater 9, and a filter 10 are provided between the inlet and outlet ends of the circulation flow path 7 to form a loop. The circulation pump 8 is responsible for promoting the flow of the heated liquid in the circulation flow path 7. It sucks the heated liquid from the outlet end of the heating system and pushes it to the inlet end to ensure that the heated liquid can circulate continuously. The water heater 9 is one of the core components of the heating system and is responsible for heating the heated liquid to a set temperature. The heater is generally an electric heater or other high-efficiency heating element that can quickly and evenly heat the circulating liquid. The filter 10 is located at the inlet end of the circulation pump 8. Its main function is to filter solid impurities or particulate matter in the heated liquid to ensure the cleanliness and smooth circulation of the heated liquid. The circulation pump 8 is started to draw the heated liquid from the outlet end into the water heater 9 for heating, and then the heated liquid is returned to the inlet end through the circulation flow path 7. In this way, the heated liquid can circulate continuously, effectively regulating the temperature inside the fermentation tank 1. The heating system can regulate the temperature inside the fermentation tank 1 by circulating the heated liquid, thereby providing a suitable temperature environment for the growth of microorganisms.

[0028] Furthermore, a stirring device 11 is provided inside the fermenter 1, and the stirring device 11 includes a drive motor 12, a reducer 13, a main shaft 14 and stirring blades 15. The drive motor 12 is installed at one end of the fermenter 1 and is fixedly installed by a support plate provided at one end of the fermenter 1. It is the power source of the stirring device 11. The reducer 13 is connected between the motor and the main shaft 14. Its main function is to reduce the speed of the motor and increase the torque to meet the stirring requirements of the stirring blade 15 on the culture medium. The main shaft 14 is provided in the fermenter 1, one end of which is connected to the drive motor through the reducer 13, and the other end is rotatably mounted on the other end of the fermenter 1 through a bearing 17. The design and installation of the main shaft 14 ensure the stability and durability of the stirring device 11. The stirring blades 15 are fixed on the main shaft 14. The stirring blades 15 are evenly spaced and are usually made of corrosion-resistant and easy-to-clean materials. The stirring blades 15 adopt an intermittent design to reduce the resistance to stirring motion, save energy consumption, and at the same time can more effectively mix the culture medium and microorganisms, thereby improving the uniformity and stability of the fermentation process. During the fermentation process, the stirring device 11, through the linkage of the drive motor 12 and the reducer 13, causes the main shaft 14 to drive the stirring blades 15 to rotate. The stirring blades 15 move inside the fermenter 1, uniformly mixing the culture medium and microorganisms, preventing the formation of material sedimentation and concentration gradients. This uniform mixing not only promotes the growth and metabolism of the microorganisms, but also ensures the consistency and stability of the fermentation process.

[0029] A spray head 16 is also provided on the top of the fermentation tank 1. The spray head 16 can be connected to a water supply pipe or a disinfectant supply pipe. The spray head 16 is used to replenish water or perform disinfection operations during the fermentation process, thereby further optimizing the fermentation environment.

[0030] Furthermore, the present application can also realize variable frequency control of the fermentation tank 1. A controller 21 is added to the fermentation tank 1 equipment. The controller 21 is a key component in the horizontal microbial fermentation equipment and is responsible for monitoring and adjusting various parameters in the fermentation process to ensure that the fermentation process is stable and efficient. The controller 21 is connected to the first temperature sensor 22 in the fermentation tank 1, the second temperature sensor 23 on the circulation path 7, and the third temperature sensor 33 set on the air heater 4. The first temperature sensor 22 is used to monitor the temperature in the fermentation tank 1, while the second temperature sensor 23 monitors the temperature of the heated liquid in the circulation path 7. The controller 21 has a built-in inverter 20 for adjusting and controlling the operation of the air heater 4, the water heater 9, the air compressor 3, the lamp trough, and the circulation pump 8. The inverter 20 can accurately control the operating speed and power output of the equipment to meet the needs and temperature control of the fermentation process at different stages. During the fermentation process, the controller 21 adjusts the working status of the air heater 4 and the water heater 9 in real time according to the temperature data obtained from the sensor to ensure that the temperature in the fermentation tank 1 is always within the set range. At the same time, the controller 21 can also adjust the gas supply of the air compressor 3 and control the lighting of the lamp trough and the disinfection effect of the disinfection lamp according to the needs of the fermentation process.

[0031] The fermentation tank 1 of the present application can not only meet the basic fermentation function of the fermentation tank 1, but also can supplement oxygen inside the fermentation tank 1 by arranging an aeration pipe 2 inside the fermentation tank 1, which is used for the fermentation of aerobic or facultative anaerobic microorganisms. At the same time, the aeration pipe 2 is connected to the air heater 4 to realize the transmission of hot air to dry and dry the inside of the fermentation tank 1. In addition, a fill light 5 is also provided on the top of the fermentation tank 1 to realize indoor temperature-controlled fermentation of photosynthetic bacteria, avoiding the influence of rainy weather, high temperature and night on fermentation. Through such a setting, the fermentation tank 1 can be diversified, giving the fermentation tank 1 richer and more practical functions, meeting the user's needs for medium and small-scale production of different types of microorganisms.
