The difference of the main body radiuses of the long stirring belt 12 and the short stirring belt 13 is utilized, so that materials at the inner core of the stirring paddle can be further uniformly mixed, the mixing efficiency is improved to a greater extent, and the discharging period is shortened.
In this embodiment, the small stirring rod 11 is vertically connected to the central rotating rod 10. The different surface angle formed by the adjacent small stirring rods 11 is 90 degrees. The length of the short agitating belt 13 is 60-80% of that of the long agitating belt 12. The spiral diameter of the short agitating belt 13 is 40-60% of that of the long agitating belt 12.
Comparative example 1
The difference from example 1 is that the long agitating belt 12 and the short agitating belt 13 are not included in this comparative example.
Comparative example 2
The difference from example 1 is that this comparative example has no short agitating belt 13 and has only a single helical structure.
