The utility model relates to a whipping device and a milk cover
machine, the whipping device comprises a mixer, the mixer comprises a spiral sleeve and a spiral inner core, at least part of the spiral sleeve extends in a
spiral line shape, and the spiral inner core is arranged in the spiral sleeve and arranged in the extending direction of the spiral sleeve. According to the invention, milk
slurry or milk liquid and air can revolve around the axis when the spiral sleeve spirally extends in the mixer and rotate around the
spiral line when the spiral sleeve spirally extends at the same time, so that the mixing degree of the milk
slurry or milk liquid and air is enhanced in a mode of combining two spiral motions; therefore, a better whipping effect is obtained, and the whipping time is shortened. Due to the relatively long length of the spiral sleeve, the path of the spiral motion of revolution can be longer, correspondingly, the number of times of the spiral motion of rotation can be increased, and therefore it can be further guaranteed that whipping meets the use requirement.
