Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a room temperature and constant humidity grain dryer that can efficiently dry grains that circulate and flow in a dryer body by using room temperature and constant humidity air obtained by a dehumidifier.

[0002]

[Prior Art]

 Conventionally, drying of grains means that the grain is exposed to dry air of low humidity, and the supplied dry air absorbs moisture in the grains and discharges the moisture out of the machine. In order to improve the drying capacity of the dry air, that is, the water absorption capacity, a dryer provided with a burner device at the air intake for heating air is disclosed in, for example, Japanese Patent Publication No. 48-36753. In addition, a dryer provided with a dehumidifier as a means for increasing the drying capacity without raising the temperature of the dry air is described in Japanese Patent Application Laid-Open No. 3-274381, for example. It is known.

[0003]

[Problems to be solved by the device]

 By the way, in the conventional dryer using dehumidified air, the dehumidifier is installed on the front side of the dryer. Generally, when the drying work is performed by one dryer, the dryer is often installed in the barn of the farmer. Perhaps there is a rice sorter or grain sorter for maintaining the rice quality, a weighing machine for bagging, etc., but it is also necessary to have a place to put the packed rice bags. For this reason, it is necessary to devise a considerable amount of equipment for the installation location of the dryer, and the large installation area of the dryer itself is a big problem. In addition, in the jointly-used drying and preparation facility, if the installation area of the dryer is large, the entire building of the facility inevitably becomes large, and as a result, the construction cost is high.

The present invention has been made in view of the above problems of the prior art, and its purpose is to provide a blower chamber provided at the left and right positions or the front and rear positions of the dryer main body. The purpose of the present invention is to provide a room temperature and constant humidity grain dryer in which a dehumidifier capable of generating room temperature and constant humidity air is incorporated to minimize the installation area of the dryer.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the room temperature and constant humidity grain dryer according to the present invention has a storage tank, a ventilation drying cylinder, and a take-out chamber which are three-dimensionally provided in a three-dimensional manner in a dryer body to the left and right positions or front and rear positions. A ventilation chamber that communicates with multiple air passages inside the body and an air exhaust chamber that communicates with multiple air passages inside the air-drying body are provided facing each other. A dehumidifier that blows constant-humidity air is housed and installed, and a suction / exhaust fan is installed on one side of the exhaust chamber.

[0006]

[Action]

 After a predetermined amount of grain is put into the storage tank and the ventilation drying cylinder, the grain is circulated in the dryer main body through the removal tank and at the same time, the dehumidifier and the suction blower are operated. By the way, the room-temperature and constant-humidity air generated by the dehumidifier enters a plurality of air ducts from the air blower chamber by the suction action of the suction air exhauster, and then the air ducts go out and out multiple grain air exhaust passages across the flowing grain. Then, the air is exhausted from the air exhaust chamber to the outside. Therefore, the grain is efficiently dehumidified and dried by the moisture absorption effect of the room temperature and humidity air flowing while flowing through the ventilation drying cylinder.

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. Since the dehumidifier is stored in the ventilation chamber provided at the left or right position or the front and rear position inside the dryer main body, compared with the conventional dehumidifying dryer that protrudes to the front side of the dryer, By significantly reducing the installation area, the grain carrier can be brought close to the grain dryer during the grain loading operation to the grain dryer, and the loading operation can be easily achieved while saving labor. Since the moist air intake port of the dehumidifier is closer to one side, it is possible to change the position of the elevator before and after, but since the dehumidifier has a built-in dehumidifier, the external cover of the dehumidifier body is not required, which is the cost. Will be cheaper. Moreover, in the present invention, since the dehumidifying air suction type is used, it is possible not only to keep the inside of the drying room clean, but also to reduce the cost of the dryer when it is installed in the shared dry preparation facility. Besides, it is possible to reduce the building cost by reducing the building area.
