The present invention discloses a device for dehulling beans, a method of dehulling beans, an apparatus for making soymilk and a method of making soymilk. The device for dehulling beans may comprise a driving motor (110); a controller (120) electrically coupled to the driving motor (110) for controlling the driving motor; and a first unit (130) coupled to and driven by the driving motor (110) to stir the beans soaked in water so as to generate a mixture containing hulls and dehulled beans. With the present invention, the beans can be dehulled before the blending process for soymilk making, so the size of particles contained in the soymilk and hence the quantity of the residue is substantially reduced.
