PROBLEM TO BE SOLVED: To provide a grain drier for circulating exhaust air that can be compactified by suppressing a depth length of a grain drying section.SOLUTION: A grain drier forms a grain falling passage (13) through which grain falls, a hot air chamber (8), and an exhaust air chamber (12), inside a box body. An exhaust air duct (20) for guiding and exhausting exhaust air sucked by an exhaust air fan (6) from the exhaust air chamber (12) to the outside of the box body, and a circulation duct (21) for supplying the exhaust air passing the exhaust air duct (20) to the hot air chamber (8), are provided. The exhaust air fan (6) is provided inside the box body, and the exhaust air duct (20) and the circulation duct (21) are provided outside the box body. |
