PROBLEM TO BE SOLVED: To provide an apparatus for deaerating a granular material, in which the amount of the air remaining in the deaerated granular material and the amount of the air to be brought into contact with the granular material at a deaeration step are minimized. SOLUTION: The apparatus 1 for deaerating the granular material is provided with a horizontal deaeration cylinder 2 having: an air chamber 9 closed/surrounded by a filtration cylinder 7 and a casing 8 for surrounding the filtration cylinder 7; a throw-in port fit to one end of the filtration cylinder 7; a discharge port fit to the other end of the filtration cylinder 7; and a horizontal screw conveyer 6 which is arranged to penetrate the inside of the filtration cylinder 7 and used for conveying the granular material from the throw-in port 4 to the discharge port. An inert gas is supplied to the inside of the throw-in port 4 from an inert gas supply port fit to the throw-in port 4 of the apparatus 1 for deaerating the granular material.
