In the conventional example shown in FIG. 3, when the basket 2 is rotated at high speed together with the turntable 3, the object A is deposited in a mortar shape by a centrifugal force as shown in FIG. When the processed material A is small like a nut or a washer, the gap between the processed materials is small, so that it is difficult for the hot air to pass through the lower part of the basket 2 and escape upward, resulting in poor drying efficiency. There was a problem of becoming. Also, in order to reduce the weight of the lid 4 for ease of operation, or to prevent the gas burner 5 and attached devices from being subjected to vibration or impact when the lid 4 is opened and closed, the burner body is attached to the outer wall of the body 1. In this case, there is a problem that a separate blower for forced air supply is required if the bending duct 12 (see FIG. 1) is used to supply the liquid to the center of the lid 4.
An object of the present invention is to solve these problems.

Normally, the object to be treated A in the basket 2 is deposited in a mortar shape on the periphery of the basket 2 by the combined force of centrifugal force and gravity. Therefore, the passage distance of the hot air is long at the lower part of the sediment, and the pressure loss is large.
When the particle size is fine, the time required for drying tends to be long.
However, according to the present invention, the passage of the hot air is limited to only the ventilation portion 9 below the peripheral frame 7 by the shielding wall 8 of the peripheral frame 7 of the turntable 3, and is arranged in a row on the outer periphery of the ventilation portion 9. Since the air in the basket 2 is drawn outward by the slats 10,
The hot air is forcibly passed through the inside of the processing object A on which the hot air is deposited to accelerate the drying, and the hot air is sucked by the negative pressure in the basket 2 even when the gas burner 5 is installed on the side wall of the body 1. Therefore, a blower for forced air supply is not required.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the present invention. A turntable 3 which is rotatably supported at the center of a body 1 so as to be horizontally rotatable is driven by a motor 13 via a transmission mechanism. The rotating base 3 is provided with a peripheral frame 7 for holding the basket 2 to be placed, and a cylindrical shielding wall 8 is provided on the upper part of the peripheral frame 7 and a wire mesh is provided on a lower part thereof. A portion 9 is formed, and on the outer periphery of the ventilation portion 9, a number of blade plates 10 are arranged in parallel in the axial direction. A lid 4 that is opened and closed by a motor is attached to an upper surface opening of the body 1, and a hot air outlet 6 is provided downward at a central lower surface of the lid 4 and attached to an outer wall of the body 1. Hot air supplied from the gas burner 5 through the bending duct 12
The suction force of the blades 10 blows out of the hot air outlet 5 into the basket 2. In the present embodiment, a part 10a of the large number of blades 10 is formed to be thick as a structure for supporting the shielding wall 8,
Of course, all the blades 10 may be used as a structure. As shown in FIG. 2, a vortex duct 14 having a U-shaped cross section is provided around the slats 10, and the air around the slats 10 is forcibly rotated by the ducts 14 to generate centrifugal force. Thus, the suction pressure can be surely formed even at a relatively low rotation speed by sending out from the exhaust port 11.
