年产4000吨植酸酶发酵车间设计

北京理工大学珠海学院2020届本科生毕业设计The graduation project's mission is to make a production plant design,whose annual output is 4,000 tons of phytase preparation.AbstractThis design is about the annual output of 4000 tons of phytase fermentation workshopdesign.In today's food processing industry,enzyme used in almost every field of foodprocessing.In the face of more and more applications of enzyme preparation.Phytase is akind of phytic acid and phytic acid catalyzed hydrolysis into inorganic phosphorus andinositol.The production process was determined according to the nature and mechanism ofthe enzyme,and the suitable ferment tank and seed tank were selected according to thematerial balance.On this basis,the quantity of various raw materials needed was obtained,and the fermentation tank,seed tank and general equipment were calculated.Finally,theworkshop layout of the fermentation factory was designed.According to the calculationresults,three drawings were designed,including the assembly diagram of the fermentationtank,the workshop layout diagram and the material flow chart.Key words:Phytase fermentation;Process design;Measure balance.
