Abstract
The utility model discloses a combination type stirring vessel, comprising a stirrer and a reactor vessel of a baffle, wherein two layers of stirrers are longitudinally arranged along the stirring axle of the stirrer and the upper layer is a paddle agitator and the lower layer is a disc turbine type agitator. The combination stirring vessel combines the paddle agitator with the disc turbine type agitator to solve the problem that the single agitator does not quickly make the fluid achieve turbulent condition and the paddle agitator makes the upper fluid horizontally surge up and stir up, thus the high-viscosity fluid quickly reaches turbulent condition and the disc turbine type agitator can generate strong shear force for the fluid action, thus the dispersion effect of the material can be optimal. The combination stirring vessel is especially suitable for the technology for extracting yolk lecithin from yolk powder using the solvent method, thus the powdery yolk lecithin is produced at high production efficiency and large production yield and the combination type stirring vessel is also suitable for other solvent extraction technology of the other substance.
