Description

[Detailed description of the invention] Industrial applications This invention relates to a grain dryer.

The problem that the invention aims to solve is to rotate the feed roll at the bottom of the drying chamber to cause the grains to flow down from the storage chamber to the drying chamber, while blowing the hot air generated by the burner into the drying chamber. In a dryer where the grain flowing down the drying chamber is exposed to this hot air to dry, if the amount of grain stored in the dryer is small, the drying chamber may not be filled with grains. In such a state, the hot air may blow through many areas of the drying chamber where there are no grains, and therefore a predetermined drying speed may not be obtained.

Means for Solving the Problem This invention provides ventilation plates (2), (2) at the bottom of the storage chamber (1).
) A vertical drying chamber (3) is provided between the drying chambers (3) so that the grains are fed out and flowed down by the rotation of the feeding rolls (4) at the bottom of this drying chamber (3), and a ventilation plate (2
), (2) are connected to the V-shaped auxiliary drying chamber (5) formed between the drying chambers (3) and the auxiliary drying chamber (5) so that the hot air generated from the burner (6) can flow down to the V-shaped auxiliary drying chamber (5) formed between the drying chambers (3) and (2). The structure of the grain dryer is provided for drying grains by ventilation.

Functions and Effects of the Invention By rotating the feeding roll (4), the grains stored in the storage chamber (1) are transferred from the storage chamber (1) to the auxiliary drying chamber (5) via the drying chamber (2). While letting it flow down, turn off the burner (
The hot air generated in step 6) is passed through the drying chamber (3) and the auxiliary drying chamber (5) for drying, but the amount of grain stored in the dryer is small and the drying chamber (3) Even when the volume is not full, the provision of the auxiliary drying chamber (5) that communicates with the drying chamber (3) expands the ventilation area of hot air, thereby reducing the amount of grains exposed to the hot air. Since the drying rate increases, a stable drying rate can be obtained at all times.

Even when the amount of grain stored is small, the provision of the auxiliary drying chamber (5) that communicates with the drying chamber (3) increases the hot air ventilation area, which makes drying difficult. Speed is always stable.
