[Detailed description of the device]

[0001]

[Industrial applications]

 In the present invention, even if the excess storage grain that cannot be stored in the circulating grain dryer is stored in the temporary storage tank due to the large amount of grain received individually, the storage grain in the storage tank The present invention relates to a grain drying device that effectively utilizes the dry hot air of a circulating grain dryer during storage to perform circulation drying, thereby promoting improvement in drying efficiency and expanding the throughput.

[0002]

[Prior Art]

 Conventionally, when the amount of grain that has been individually received is large and cannot be stored in multiple circulating grain dryers, the excess grain is temporarily stored in multiple storage tanks and then stored. Prior to the filing of this application, a joint drying facility that supplied the stored grains to the circulating grain dryer to dry all the grains received when the grains in the circulating grain dryer were dried and discharged , JP-B No. 53-26392, JP-B No. 55-224478, etc.

[Problems to be solved by the device]

 By the way, the conventional storage tank stores the grain for a certain period of time while preventing the decay and deterioration of the surplus grain for that purpose. It was only exposed to the room temperature air obtained. Therefore, in the storage tank, since no drying work is performed during storage, it takes a certain amount of time to dry a large amount of grain, and the drying time cannot be shortened. Was there.

The present invention has been made in view of the above problems of the conventional technology, and an object thereof is to circulate a tank for storing surplus grains in a circulation type elevator through a circulation elevator. In addition to making it possible to flow, the switching operation of the switching damper allows the drying hot air used in the circulation type grain dryer to be circulated from the hot air chamber side to the exhaust chamber side at any time to perform drying, thereby improving the drying efficiency. The present invention aims to provide a grain drying device that improves the yield, shortens the drying time, and expands the throughput.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the grain drying apparatus of the present invention has a circulation system provided with a hot air blower chamber and a suction / exhaust chamber which communicate with a ventilation drying section in a dryer body having a circulation elevator on one side. Type grain dryer and a circulation type storage tank provided with a hot air chamber and an exhaust chamber communicating with the ventilation drying section in the main body with a circulation elevator installed on one side, and the hot air blowing chamber and the hot air blowing chamber. The chamber, the suction / exhaust air chamber, and the exhaust air chamber are connected via a hot air communication duct and an exhaust air communication duct that are provided with switching dampers.

[0006]

[Action]

 When a large amount of grain is received, it is put in the circulating grain dryer first, then the surplus grain is put in the circulating storage tank, and then the switching damper is operated together with the open side and the circulating grain is Operate dryer and circulating storage tank. By the way, when the suspended grain is circulated and fluidized in the dryer main body and the main body through the respective circulation elevators, and the circulated fluidized grain passes through the respective ventilation drying sections, the hot air blowing chamber From the suction side of the suction / exhaust chamber and from the side of the hot air chamber toward the side of the exhaust chamber is dried by being exposed to hot dry air. Therefore, even if a large amount of grain is received, drying the grain at the same time with the circulating grain dryer and the circulating storage tank can significantly increase the drying efficiency and increase the drying amount. It can be realized or the drying time can be shortened. When it is not necessary to circulate and dry the grains in the circulation type storage tank during operation of the circulation type grain dryer, the hot air communication duct and the exhaust air communication duct can be closed by the switching damper so that the dry hot air can be circulated. Since it does not flow in the storage tank, it is not dried. In addition, while the circulating grain dryer is in operation, when it is desired to simply store the grains stored in the circulating storage tank, the hot air communication duct side is closed by the switching damper, and the exhaust air communication duct side is operated by the switching damper. When opened, the outside air circulates in the circulating storage tank due to the negative pressure in the exhaust chamber, and the grains are stored without deterioration and deterioration.
