Description

Technical Field

[0001] The invention relates to the field of fermentation tanks, in particular to a tea accelerated fermentation tank device. Background Art

[0002] In bioengineering, especially fermentation engineering and its research and testing, fermentation tanks are the main equipment required, and fermentation tanks often need to control temperature. Although in most cases, the temperature of such fermentation tanks can be allowed to fluctuate within a certain range, exceeding a certain limit will destroy the biochemical conditions required for normal fermentation, resulting in a decrease in fermentation speed or even termination of the fermentation process and process failure. In addition, some fermentation processes require the control of the upper and lower limits of the temperature, or the same material is subjected to different temperatures at the same time. At this time, the current fermentation process or fermentation tank system is no longer applicable. In particular, in some experimental studies, the appropriate fermentation temperature may not be known, which requires experimental exploration, and a device that can efficiently support this type of fermentation temperature exploration is required. This device should make the temperature in the fermentation tank adjustable within a wide range and can remain stable at multiple given values, which is a bottleneck that is difficult to pass for temperature control with unidirectional (temperature increase direction) characteristics. In addition, the fermentation of microorganisms on solid substrates involves temperature control, mass transfer, air and other aspects. Due to the immobility of the substrate, in conventional fermentation tanks, many difficulties are brought to actual operation, especially the difficulty in achieving the separation of products in continuous fermentation. In order to solve this problem, an accelerated fermentation system can be designed. With the help of temperature conduction of a controllable heating system, the temperature of the target object can be controlled, and continuous feeding and emptying of materials and online separation of products can be achieved simply and conveniently. To this end, we proposed an accelerated fermentation method with temperature control. Summary of the invention
