Abstract
Description
Technical Field
[0001] The invention relates to the technical field of microbial fermentation, in particular to a microbial low-temperature inoculation and fermentation device. Background Art
[0002] The background technology of the low-temperature inoculation fermentation device of microorganisms mainly relates to the inoculation technology in the process of microbial fermentation. Before the start of microbial fermentation, a certain number of pure microbial strains need to be cultivated in an aseptic environment. When the fermentation tank is put into the configured culture medium, it needs to be cooled to the temperature required by the process after high-temperature disinfection. Subsequently, the prepared microbial strains are transferred to the fermentation tank under aseptic conditions. This process is called inoculation. During the inoculation process, the inoculation device is required to maintain a closed aseptic state throughout the inoculation process to avoid fermentation failure caused by contamination of miscellaneous bacteria. In the production process, a fire ring is usually used to protect the inoculation. After the tank pressure drops to zero, the seeds are poured into the seed tank as soon as possible. During inoculation, no air can be discharged and no air can flow in the environment. However, the fire ring inoculation process requires the cooperation of multiple people and has high requirements for operators. There is a great risk of contamination during the process of reducing the pressure to zero after flame sterilization, which is easy to fail to ferment, resulting in direct and indirect economic losses. In addition, the temperature and pressure in the fermentation tank are not easy to control, which also greatly reduces the success rate of inoculation.
[0003] Therefore, in order to improve the efficiency and success rate of microbial fermentation, it is necessary to develop a new type of low-temperature microbial inoculation and fermentation device. This device should have better sterility maintenance capabilities, which can reduce the risk of contamination during the inoculation process, and should also have better temperature and pressure control capabilities to improve the success rate of inoculation. In addition, the new inoculation and fermentation device should also consider the simplicity and safety of operation to reduce the difficulty of operation and personnel costs.
[0004] In the process of microbial fermentation, in order to reduce the energy waste generated during the fermentation process, it is often necessary to use a microbial low-temperature inoculation fermentation device. The existing microbial low-temperature inoculation fermentation device has a good energy-saving effect when in use, but the device cannot ensure that the internal temperature is maintained at a high level to facilitate microbial fermentation while ensuring the air circulation required for internal microbial fermentation.
