FLIGHT CONVEYOR

PROBLEM TO BE SOLVED: To provide a flight conveyor that can reduce occurrence of deposition and prolong service life of a chain.SOLUTION: A floating preventing guide 50 preventing floating of the chain 20 advancing in a conveying direction is provided above the chain 20 such that a gap g is made between a casing 10 and the guide 50. Water vapor discharged from concentrate C accumulated in space S between the chain 20 and the casing 10 is discharged from the gap g, whereby sticking of the concentrate C to the casing 10 can be reduced. Since the concentrate C accumulated in the space S between the chain 20 and the casing 10 is discharged from the gap g, the occurrence of the solid deposition of the concentrate is reduced.
