Abstract

A drying apparatus of the present invention includes a drying tank for performing drying processing of a workpiece, a fixture for the workpiece, heating means opposed to a front surface of the workpiece, and heating means opposed to a back surface of the workpiece, wherein each heating means is inclined from a horizontal line in its longitudinal direction.

First claim

What is claimed is:

1 . A drying apparatus comprising:
a drying tank for performing drying processing of a workpiece, a fixture for the workpiece, a heating means opposed to a front surface of the workpiece, and a heating means opposed to a back surface of the workpiece, wherein each heating means is inclined from a horizontal line in its longitudinal direction.

2 . The drying apparatus according to claim 1 , wherein said drying tank includes a gas injection means opposed to the front surface of the workpiece and
a gas injection means opposed to the back surface of the workpiece, wherein a nozzle hole of each gas injection means is inclined obliquely downward.

3 . The drying apparatus according to claim 1 , wherein said drying tank includes a conveying mechanism of the fixture.

4 . The drying apparatus according to claim 2 , wherein said drying tank includes an exhaust port provided in a bottom surface thereof.

5 . The drying apparatus according to claim 4 , wherein said drying tank includes a gas straightening plate that is provided above the exhaust port to allow gas injected through the nozzle hole to strike on the gas straightening plate.

6 . The drying apparatus according to claim 5 , wherein a surface of said gas straightening plate which faces the workpiece has a curved shape being convex upward.

7 . The drying apparatus according to claim 2 , wherein said gas injection means includes a lifting mechanism.

8 . The drying apparatus according to claim 1 , wherein said drying apparatus further includes
a front tank provided on an inlet side of the drying tank, and a rear tank provided on an outlet side of the drying tank, wherein the front tank and the rear tank each have a gas injection means opposed to the front surface of the workpiece and a gas injection means opposed to the back surface of the workpiece.

9 . The drying apparatus according to claim 8 , wherein said gas injection means is provided at least at one of a position facing an upper portion of the workpiece and a position facing a lower portion thereof.

10 . The drying apparatus according to claim 8 , wherein said drying apparatus further includes a reserve heating tank provided on an inlet side of the front tank,
wherein the reserve heating tank has heated liquid injection means.
