DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an air conditioner in which a lower part of a drying storage installed outdoors is divided vertically by a ventilation floor, and a drying room is formed in an upper part and a ventilation room is formed in a lower part. The present invention relates to a cereal drying storage device for drying by passing heated air through a cereal layer.

[0002]

2. Description of the Related Art Conventionally, grains loaded in a tank (grain tank) are circulated and flowed by operating a loading conveyor, a vertical auger, a grain transport device and a grain raising machine. While the drying air obtained by the hot air generator is circulated upward through the airflow floor and dried, and then the kernels are dried to a predetermined moisture, a conveyor for filling, a vertical auger, a kernel conveying device and Drying the grain by stopping the operation of the grain-lifting machine and keeping the grain stationary, allowing natural wind to flow upward from below and storing the grain while finishing drying
The apparatus is known, for example, as described in JP-B-63-40579 before the present application.

[0003]

By the way, in the conventional drying apparatus of this type , the drying operation and the storage operation of the grain are performed while the drying air and the natural air are blown upward from the whole surface of the ventilation floor while being blown. However, since a considerable amount of grains are stored in a high state in the grain tank,
Regardless of how the grains are circulated and flowed through a fryer, or are stirred and flowed with a vertical auger, the lower grains that are strongly blown by the dry wind that is forcibly pumped upward from the entire ventilation floor will not The horizontal auger is placed on the ventilation floor to prevent the lower end of the vertical auger from colliding with the horizontal auger that revolves while rotating on the ventilation floor during circulation drying work, as well as drying faster than the upper grain. The phenomenon that the kernels deposited at approximately the same height as the height of the kernel will be in an unstirred state, and furthermore, if a ventilation path of a size that is any cause is once formed in the sedimentary kernel layer, the phenomenon such that pumping air can not be blown toward a uniform pumping air from the blow-air bed entirely above the the air passage upward, huh underlying grain becomes excessive drying condition Rika, a furnace and blower Consists of Wind generator is a relationship that is installed outdoors, large noise during dry storage operation, after causing noise pollution, failure to be corroded by wind, rain may frequently occur, there is a problem of poor durability Was.

According to the present invention, a heat exchange room having a built-in grain drying storage and a heat source device is installed outdoors.
The ventilation path connecting the heat exchange chamber and the blower is inserted deeply into the ventilation room of the grain drying storage, and the blower is stored at the back of the ventilation room. Is it possible to prevent corrosion of the blower due to wind and rain and to increase the durability? By simply switching the damper and the switching operation of the damper, warm air is allowed to flow upward from below and downward from above to the grain. If a part of the cereal is dried evenly without becoming over-dried, or if the operation of the heat source device is stopped, the same dry storage is used to distribute the dry cereal in the open air, and the cereals are in good taste without loss of quality. It is an object of the present invention to provide a grain dry storage device that can be stored for a long period of time.

[0005]

Means for Solving the Problems To achieve the above object, a grain drying and storage apparatus of the present invention is characterized in that a drying chamber is divided into upper and lower sections by a ventilation floor in a drying storage room installed outdoors. This is a grain drying and storage device that forms ventilation chambers at the bottom, and allows heated air to flow through the grain layers stored and deposited in the drying chamber for drying.
Connected to a heat exchange room equipped with a heat source device inside.
Insert the air duct deep into the ventilation chamber of the drying storage, and
A fan is connected to one end of the ventilation room
The blower is located in the back, and the space above the dry storage
A connection duct is used to connect the heat exchange chamber with the intake port.
In addition, the discharge side of the blower is switched by a switching damper
Connected to the ventilation room or outside by the dry storage
Exchange in the connecting duct connecting the upper space of the building and the heat exchange chamber
On the connection side with the chamber, connect the connection duct to the air inlet of the heat exchange chamber.
Or a pressurized exhaust port that communicates with the outside air.
Characterized in that it comprises a damper .

[0006]

According to the grain drying and storage apparatus of the present invention, hot air is sucked in from the heat exchange chamber by the blower and blown into the ventilation chamber of the drying storage as heated and pressurized air, and the grain layer in the drying chamber flows upward. or it is allowed to discharge to the outside from the upper space of the drying reservoir and, or by inhalation ventilation room air drying reservoir by blower blows air to the heat exchange chamber as a pumping air, and from the upper space of the drying reservoir through the air guide path Since the grain layer can be circulated downward and can be discharged to the outside from the blowing chamber, the heated air is directed upward from below (in the direction of the solid arrow in FIG. 2) to the sediment in the dry storage. Drying can be carried out by pressurizing and circulating the heated grain, or by suction drying the heated air downward from above (in the direction of the dashed line arrow in FIG. 2).

When the grains dried as described above are stored using the same dry storage, the operation of the heat source device is stopped in the above-mentioned state, and only the outside air is directed downward from above to the dried grains. Or, if it is distributed upward from below, the dried cereals can be stored for a long time without deteriorating the quality.
