Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a conditioning chamber for a grain dryer.

[Prior art and problems to be solved by the invention] When the temperature of the atmosphere in the conditioning chamber inside the grain dryer is high, the grains being tempered may become stuffy and dew condensation may form on the side walls of the conditioning chamber. This becomes a factor that inhibits grain flow.

[Means for Solving the Problems] The present invention quickly removes moisture inside the grain machine and allows the grain to flow smoothly from the tempering chamber to the lower grain chamber. We took technical measures such as: That is, a tempering chamber 2 in which grains to be accommodated are tempered and dried while flowing downward into a drying chamber 1 through which hot air passes.
The structure of a conditioning chamber of a grain dryer is provided with an exhaust fan 4 that is driven to discharge air when a moisture sensor 3 detects moisture in grains in the conditioning chamber exceeds a predetermined level. do.

[Operations and Effects of the Invention] The grains in the tempering chamber 2 flow down into the drying chamber 1 below while undergoing a tempering action, and are heated by hot air.
Drying is performed in sequence while being circulated again to the conditioning chamber 2. At this time, when the moisture content of the grains in the conditioning chamber 2 is high, the moisture sensor 3 detects this and drives the exhaust fan 4 to exhaust the interior of the conditioning chamber 2, so that dehumidification is possible. The drying process is carried out, 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 grains are exposed to the surrounding wall surface of the grain conditioning chamber 2 or from this conditioning chamber 2. By reducing the frictional resistance due to moisture when flowing down to the narrow sloped board surface on the lower side, it is possible to maintain a smooth flow of grains, and therefore it is also possible to dry wet grains. be.

[Example] An embodiment of this invention will be described based on the drawings.

The dryer is of a circulation type, with the tempering chamber 2 located at the top and the drying chamber 1 at the bottom. Inside the drying chamber 1, hot air is blown by a burner to heat the grains flowing down. A grain raising machine 6 is provided between the grain collecting room at the bottom of the drying room 1 and the supply gutter 5 at the top of the tempering room 2 to circulate the dried grains. 7 is a discharge chute.

One or more exhaust fans 4 are installed on the ceiling of the conditioning chamber 2, and a fan is installed inside to be driven by an electric motor.Moreover, the moisture sensor 3 is installed on the side of the conditioning chamber 2. The moisture sensor 3 and the exhaust fan 4 are installed in a corner of the room to detect moisture in the room 2, and when the moisture sensor 3 and the exhaust fan 4 are detected to be more than a predetermined moisture level, the exhaust fan 4 is energized and driven, and the following moisture detection When this occurs, the interlocking configuration is configured to stop the operation.

At the beginning of the drying process, particularly when grains with excessive moisture are being dried, the moisture content in the conditioning chamber 2 is high, and the exhaust fan 4 is often activated by the sensor 3. Further, even after drying, water droplets are generated on the inner circumferential surface of the tempering chamber 2 due to dew condensation, and if this can be detected by the moisture sensor 3, it is possible to remove the moisture at the time of this dew condensation. This 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.
