Stirring mechanism for producing recombinant teriparatide through high-density fermentation of escherichia coli

The utility model belongs to the technical field of medicine production equipment, and provides a stirring mechanism for producing recombinant teriparatide through high-density fermentation of escherichia coli, which comprises a driving device, a spraying ball, a driving shaft, a tank shell, a stirring paddle II, a stirring paddle I, tank support legs, a stirring paddle III and the like. A good stirring effect is achieved through high-density fermentation of the escherichia coli, and the protein expression quantity of recombinant teriparatide produced through fermentation of the escherichia coli is increased under the condition that the process rotating speed is not changed. 本实用新型属于是医药生产设备技术领域，提供了一种用于大肠杆菌高密度发酵产重组特立帕肽的搅拌机构，所述搅拌机构包括：驱动装置、喷淋球、驱动轴、罐壳、搅拌桨二、搅拌桨一、罐支腿、搅拌桨三等元件组成通过搅拌桨的设计改良后，大肠杆菌的高密度发酵获得了较好的搅拌效果，在工艺转速不变的情况下，大肠杆菌发酵产重组特立帕肽的蛋白表达量。
