Abstract
Description
Technical Field
[0001] This utility model relates to the field of microbial fermentation technology, and in particular to a microbial fermentation device. Background Technology
[0002] Microbial fermentation refers to the process by which microorganisms, under aerobic or anaerobic conditions, oxidize and decompose organic matter through catabolism, and simultaneously synthesize their own cellular substances and metabolic products through anabolism using intermediate products and energy generated from catabolism. Simply put, it is the process by which microorganisms use substrates to grow, reproduce, and produce useful substances.
[0003] Microbial fermentation uses microbial fermentation equipment, also known as fermentation tanks, which are containers that provide a good environment for the operation of a specific biochemical process of microorganisms. In industrial fermentation, it generally refers to equipment for deep cultivation of microorganisms. It is usually made of stainless steel cylinder and is the place for cultivating and fermenting various microorganisms. It has good sealing properties to prevent the microorganisms from being contaminated. It is available in different volume specifications to meet the needs of different production scales.
[0004] In existing technologies, mechanically stirred and ventilated fermenters utilize mechanical stirrers to generate strong stirring and mixing of the fermentation broth within the fermenter. Simultaneously, sterile air is introduced through a distributor at the bottom, causing the air to form microbubbles in the fermentation broth and fully contact and mix with it. This provides sufficient oxygen for aerobic microorganisms, meeting their growth and metabolic needs. During fermentation, the fermentation temperature is controlled by a heating and cooling system, and the pH value is adjusted by adding substances such as acids and alkalis, allowing microorganisms to multiply and synthesize target products under suitable environmental conditions. Microbial fermentation has strict temperature requirements, so a temperature control system is installed inside the tank to regulate the temperature and ensure microbial activity. However, uneven temperature coverage by the temperature control system leads to reduced microbial activity, and the high pressure inside the tank is also detrimental to the activity of fermenting bacteria.
