Abstract：Fermentation technology became population from the invention of medicines such as penicillin, and then has been widely used in many industry fields which are chemical industry,food,pharmacy,energy et al.Now,fermentation is the most important technology in the biological industry. .According to the standards and other reference,thicknesses of the cylinder and the spherical heads have been calculated for a fermentation tank whose capacity is 50m3.Theoretical and experiment formulas have been used to analyze the heat transfer areas for the fermentation tank;after calculating and choosing transmission,then finishing the design of agitation equipment;area replacement method has been used for calculating the reinforcement area of the five openings which do not agree with the principles of exemption for reinforcement.Fermentation tank is the key equipment in the fermentation process,and studies of the design theory and strength for the fermentation tank in this paper is of a significant sense for biological engineering
Key words:Fermentation tank;Structure design;Stirring shaft;Reinforcement
