Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conditioning chamber of a grain dryer, which quickly removes moisture inside the dryer and prevents grain from flowing from the conditioning chamber to the lower drying chamber. This is to ensure that the process is carried out smoothly.

For this reason, the present invention has taken the following technical measures. That is, the grains to be stored are placed in a drying room (1) with hot air ventilation at the bottom.
At the top of the tempering chamber (2), which is tempered and dried without being allowed to flow down,
The grain dryer's conditioning chamber is provided with an air exhaust fan (4) that operates in conjunction to exhaust air when a moisture sensor (3) in the conditioning chamber (2) detects moisture above a predetermined level.

This invention has the following technical effects due to such a configuration. That is, the grains in the conditioning chamber (2) flow down to the drying chamber (1) below while undergoing conditioning, are heated by hot air, and are sequentially dried while being circulated back to the conditioning chamber (2). is to be carried out. At this time, if the moisture in the conditioning chamber (2) is high, the moisture sensor (3) detects this and drives the exhaust fan (4) to exhaust the air in the conditioning chamber (2). Because of this, dehumidification is performed, and the grains that are being dried or stored do not swell due to excessive moisture, and while the dried grains are flowing down, the surrounding wall surface of the grain conditioning chamber (2),
It is possible to reduce the frictional resistance due to moisture when flowing from this tempering chamber (2) to the lower narrow inclined board surface, etc., and maintain a smooth flow of grains. It also enables drying work.

In addition, in the drawing, the dryer is of a circulation type, and the refining chamber (2) is located in the upper part and the drying chamber (1) is located in the lower part. A drying room (
1) A grain raising machine (6) is provided between the lower grain collection room and the conditioning room (2) and the upper supply gutter (5) to circulate the dried grains. (7) is a discharge chute.

One or more exhaust fans (4) are installed as appropriate on the ceiling of the conditioning chamber (2), and a fan is installed inside to be driven by an electric motor. It is located at the side corner of the pawn chamber (2) and is installed so that moisture in the chamber (2) can be detected.
The moisture sensor (3) and the exhaust fan (4) are configured to be interlocked so that the exhaust fan (4) is energized and driven when moisture above a predetermined moisture level is detected, and is stopped when moisture below a predetermined level is detected.

At the beginning of the drying process, especially when drying grains with excessive moisture, the exhaust fan (4) is likely to be activated by the sensor (3) when the moisture content in the conditioning chamber (2) is high.

Furthermore, even after drying, water droplets are generated on the inner peripheral surface of the tempering chamber (2) due to dew condensation, and if this can be detected by the moisture sensor (3), it is also possible to eliminate moisture when the dew condensation occurs. It also reduces the chance of wetting the grains.

The moisture sensor (3) may also be provided on the inner surface of the peripheral wall of the drying chamber (1) to detect dew condensation, or may be provided in the middle of the drying air exhaust path.

Claims (1)

[Claims] The moisture sensor (3) in the tempering chamber (2) at the top of the tempering chamber (2) where the stored grains are tempered and dried without flowing down into the drying chamber (1) with hot air ventilation at the bottom. A tempering chamber of a grain dryer is provided with an air exhaust fan (4) that operates in conjunction to exhaust air when a moisture content exceeding a predetermined level is detected.
