Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a grain dryer.5 Problems to be Solved by the Invention While grains are flowing down from an upper storage chamber to a lower drying chamber, grains are generated in a burner. In a dryer that crosses the drying chamber by sucking hot air with a rear exhaust fan, and exposes the grains flowing down the drying chamber to this hot air and dries them, the amount of grains stored in the dryer can be reduced. If there is a small amount of grain, the drying chamber may not be filled with grains, and in such cases, the hot air blows through areas of the drying chamber where there are no grains, reducing the drying speed or causing the grains to dry. Since the amount of grains is small, the time required for tempering is short, which may result in the occurrence of shell side or crushed grains.

Means for Solving the Problem The present invention provides a method for reducing the amount of grain supplied to the upper storage chamber (1) from the burner (3) in front of this drying chamber (2) while flowing it down into the lower drying chamber (2). Exhaust fan Q4) via drying room (2)
In a circulation dryer of the type that dries with hot air that is sucked and discharged into the storage chamber (1), a valve 6) that can be opened and closed can be partitioned off to store grains in only a part of the storage chamber (1).
The grain dryer is equipped with a valve (6) that can be opened and closed to blow air into the storage chamber (1) and the corresponding drying chamber (2), which are partitioned by the valve (6), in the hot air path passing through (2). composition.

"Actions and Effects of the Invention" The grains accommodated in the second storage chamber (1) are
The hot air generated by the burner (■) while flowing down from the drying room (21) from 1) is sucked by the exhaust fan (4), and the drying room (21)
Circulating drying is performed in which grains are cross-ventilated and dried by being exposed to this hot air, but even when the amount of grain stored in the dryer is small, a A state in which the grains to be stored are stored only in a part of the storage chamber (1) and the drying chamber (2) by operating the valve 6) that blows air into the drying chamber (2) and the valve 0 that can be opened and closed to blow air into the drying chamber (2). At the same time, the hot air path on the side without grains is blocked by the valve (2), so the hot air does not blow through the drying chamber (2), and since it is stored only on the side, the storage chamber From inside the drying room (2
), the circulation time of the grains flowing down becomes longer, so the tempering time becomes longer, so the drying rate does not decrease, and the generation of copper agent and broken grains can be eliminated.

Example In the illustrated example, the wall of the dryer ■ has a rectangular shape in plan view that is long in the front and back direction, and consists of front and rear wall plates (8), (8), and left and right wall plates (ω, (ω). This configuration has a ceiling plate 0 and OI.

A vertical drying chamber (2,
There are delivery valves o and o provided at the bottom of (2). An inclined plate is provided above each of the ventilation mesh plates, and a partition plate is provided below, and a ventilation chamber υ is formed between the inner ventilation mesh plates, which communicates with the burner (■) provided on the front wall plate (8). A ventilation chamber 00, ■ is formed between the left and right outer ventilation net plates and the left and right wall plates ■, ■, and a box-shaped ventilation passage chamber O' of this ventilation chamber O communicates with ■. ?) is installed on the ) part of the rear wall board, and this ventilation duct room 0 has 11: wind 41! ■
The exhaust fan (4) and the exhaust chamber Qe are connected to each other.

A storage chamber (1) is formed on the upper side of the drying chamber (2), and the front and rear wall plates (8) forming this storage chamber (1), (II

Attach the shaft (6) to the edge of this partition plate fnl to the front and rear wall plates (8),
(8) is rotatably supported between them, and a valve 6) is fixed to this shaft 0, a lever (6) is attached to the front end of the shaft 0, and a lever @ is attached to the rear end of the shaft 0.
The lever (4) can be fixed to a fixing plate provided on the front wall plate (8). An axle is rotatably supported between the upper and lower wall plates of the exhaust duct chamber Q71, and a valve [

A two-part helical transfer gutter @ is provided along the upper helical transfer gutter (c), and a supply port for supplying the transferred grains into the storage chamber (1) is opened in the center of this upper helical transfer gutter (c). A diffuser panel is provided at the bottom.

When the amount of grains to be stored in the drying chamber (1) is small, by operating the lever (6), the valve (6) rotates and the grains are transported from the upper helical transfer gutter (C) through the diffusion plate. The storage chamber (1
) The grains that are diffused and supplied into the storage chamber (1) are diffused and accommodated only on one side of the storage chamber (1), and at the same time, the valve 0 rotates, and this valve 0 is placed on the side where no grains are stored. This is a configuration in which the terminal end of the ventilation chamber is closed.

In the illustrated example, the terminal end of the ventilation chamber Oe is closed with the valve, but the valve is provided on one side of the ventilation chamber υ to close the end of the ventilation chamber 0'3. It may be configured such that one side of the valve is closed by the valve. Further, the central part of the storage chamber (1) is provided with the partition plate (G) and the valve 6) in the left-right direction, and the central part of the ventilation chamber 09 is provided with the valve (6) in the left-right direction.
