Research Of Heat-transfer Property And Simulation Of Temperature Field On Microorganism Fermentation

The application of biological fermentation technology is quite widespread.Which can alleviate the energy to be short. The form of lack energy causes the imperative development of fermentation engineering technology industry. Conducting the academic research on fermentative process, especially in the heat transfer aspect and the temperature field simulation, enhances the efficiency of controlling temperature on the large-scale industrial fermentation process. Which have the important project application significance.Domestic and foreign researcher have all done some thorough research on the biological fermentation base preparation, the fermentative process control optimized, the fermentation generator and its supplementary equipment, and so on. But it is imperfect. Correspondingly, the fermentation engineering has applied very much. Because some important technologies wait for the solution, the domestic fermentation engineering application is relatively. It has less been researched at the aspect of fermentation heat transfer. The author researched microorganism fermentation heat-transfer property and its temperature field distributed characteristic with the union method of the experimental study, the theoretical analysis and the value simulation.Which provide the theory reference for the later fermentation engineering application. In this article first there is a cube box, to manufacture with the PVC board whose side length is the 300mm. According to the needs, the thermo-element is arranged, the heat preservation work is completed, and then the fermentation laboratory bench was done well. Gradually they are made on the natural fermentation of orange peel dregs and grape's nature fermentation test. It has been familiar about the fermentation process step and the matters attention neededThe on-line gathering temperature data are carried on the processing at the end of the fermentation experiment, and then the result is the temperature time graph. According to the diagram of curves comparative analysis, finally it indicates the fermentation has gradualness. The temperature unceasingly changes as necessary, which shows the fermentative process has the heat source production. The temperature rise is obvious in the fermentation process. It shows that the fermentation response is the exothermic reaction.The author has carried on the natural parameter test to the fermentation specimen,...
