Abstract

PURPOSE:To reduce the installation area of a grain dryer and improve the charging efficiency of grains into an elevator by a method wherein the reserving chamber of grains is provided at the upper part in a machine wall and a drying chamber as well as a grain collecting bucket are provided in the lower part of the same while the elevator of the grains is provided in the machine wall of the other side. CONSTITUTION:Grains, received into a reserving chamber 2 in the wall 1 of a grain dryer, are dried by hot air, generated from a burner 16 and passing through a drying chamber 3, while being fed from the reserving chamber 2 into the drying chamber 3 and flowing down through the same chamber 3, then, the grains are collected to a central part in the fore-and-aft direction of a grain collecting bucket 4 and are supplied into an elevator 5 from the grain collecting bucket 4 while the grains are dried by repeating the upward carrying by the elevator 5 and the returning into the reserving chamber,2. In this case, the elevator 5 is installed in the machine wall 1 and, therefore, a part extended outwardly to the outside of the machine wall 1 is reduced whereby the installation area of the drier can be decreased. On the other hand, the grains can be thrown into the elevator 5 directly from the side of the machine wall 1 and, therefore, the charging efficiency of the grains can be improved.
