Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
Referring to Fig. 1, this utility model provides a kind of Zymolysis Equipment producing citric acid, including fermentation tank 10, shaft 20 it is provided with inside this fermentation tank, described shaft 20 has the three grades of stirring vanes set gradually from top to bottom, wherein: first order stirring vane 21 and third level stirring vane 23 are SANYE slurry type, second level stirring vane 22 is six leaf slurry types.
In concrete application, described first order stirring vane 21 and the second level stirring vane 22 spacing on described shaft 20 are 1200mm, described second level stirring vane 22 and the third level stirring vane 23 spacing on described shaft are 1000mm, and each blade of described second level stirring vane 22 is parabola shaped.Reasonable setting based on this structure, it is possible to improve greatly stirring efficiency, energy efficient.
Preferably, described fermentation tank 10 is also associated with a gas distributing pipeline 30, and the two ends being positioned at gas distributing pipeline 30 intercept within described fermentation tank 10 are equipped with some circular cloth QI KOU 31, and described circular cloth QI KOU 31 is inclined to set relative to the horizontal plane at described gas distributing pipeline place.
In concrete application, shaft 20 is rotated by the driving of external force (motor 40), and to rotate clockwise, three grades of stirring vanes in fermentation tank 10 are by the feed liquid in the driving stirred fermentor 10 of shaft 20.Owing to have employed three grades of stirring vanes, and second level stirring vane 22 additionally uses six leaf parabola slurry types so that Zymolysis Equipment of the present utility model stirring is more uniform.
