A sieving device having a mesh screen detachable from a frame body is capable of easily removing particulate material remained on the mesh screen and cleaning of the mesh screen and being installed even in a confined space requiring a sanitary condition. The particulate material sieved through the mesh screen is prevented from getting out of a collecting container or scattering around. With a vibration generating means in the sieving device, sieving vibration can be efficiently produced with a relatively small power with preventing coagulation and agglomeration of the particulate material. By corrugating the bottom of the mesh screen, the efficiency of sieving the particulate material can be increased remarkably.
