PURPOSE:To smooth ejection of powder and prevent the staying of powder efficiently by providing a fixed blade arranged spirally on a rotary shaft at a downward angle in an opposite direction to a rotary one in addition to blades. CONSTITUTION:An external cylinder 102 is coaxially arranged on an external periphery of a heating cylinder 101 to form a vapor passage 103. On the other hand, a rotary shaft 107 is coaxially arranged on the internal surface of the heating cylinder 101. On this rotary shaft 107, blades 117 are fitted in a zigzag fashion. In the meantime, a fixed blade 121 is spirally installed at a downward angle in an opposite direction to the rotational direction of the rotary shaft 107, on the rotational shaft in the heating cylinder 101. This fixed blade 121 is arranged in such a way that it passes between blades 117, and fixed to the rotary, shaft 107 via a support. This fixed blade 121 discharges powder forcibly by creating a downward force to the powder, thus inhibiting the staying of the powder efficiently. |
