Abstract
A discharge apparatus for a powdered or granular material provided at a lower end of a storage part in which a powdered or granular material is stored. The discharge apparatus comprises a material discharge passage connected to the lower end of the storage part and provided with a material discharge port at the terminal end, a valve body opening or closing the discharge port of the material discharge passage, and a valve driving part moving the valve body along a substantially orthogonal direction to a surface of a valve seat around the discharge port. The valve body is so constructed as to form a gap at closed position between the valve body and the surface of the valve seat along the circumferential direction of the discharge port, in which the gap is formed such that a powdered or granular material is not allowed to pass therethrough.
