Description

[Detailed description of the invention] Industrial applications This invention relates to a grain dryer.

Conventional technology In the past, grains fried using a grain raising device were fed into a storage chamber through an input port, and from this storage chamber the grains were fed into a drying chamber using a delivery valve and flowed down the edge, repeating the cycle while being exposed to hot air generated from a burner. This device exposes and dries the grains flowing down, and does not have a device that can change the rotation of the delivery valve to low-speed or high-speed rotation by rotating the guide plate left and right.

Problems to be Solved by the Invention The grains are dried by repeating the process of drying the grains by exposing them from the input port to the hot air generated from inside the storage chamber. When the amount of grains to be stored and dried in the storage chamber is small, the number of times the grains are circulated increases, which may result in increased damage to the grains.

Means for Solving the Problems The present invention has a system in which hot air generated from a burner (3) is fed into the lower side of a storage chamber (1) in which grains are stored, while the grains are fed out and flowed down by a delivery valve (2). A drying chamber (5) is provided in which air is sucked and exhausted by an exhaust fan (4), and grains are fed into the front part of the storage chamber (1) through an input port (6) provided at the top of the storage chamber (1). A grain raising device (7) for feeding the grains, and rotatable guide devices (8) for guiding the grains into the storage chamber (1) are provided on both left and right sides of the input port (6). The grain dryer has a structure in which the rotation of the delivery valve (2) is controlled to high speed rotation or low speed rotation in conjunction with the left and right rotation operation (8).

Effect of the Invention The grains fried by the grain raising device (7) are fed into the storage chamber (1) from the input port (6) while being guided by the guide plates (8) on both the left and right sides of the input port (6). from the storage chamber (1) into the drying chamber (5) using the dispensing valve (2),
The grains flowing down are exposed to the hot air generated from the burner (3) and the cycle of drying is repeated and the grains are dried.

When the number of grains to be stored in the storage chamber (1) and dried during this drying work is small, the guide plate is arranged so that the grains are fed to one side of the storage chamber (1). When (8) is rotated to one side, the rotation of the feed valve (2) is controlled to be changed to low speed rotation in conjunction with this rotation operation, and the grains are fed out and dried by this low speed rotation. .

Effects of the Invention According to this invention, when the amount of grains to be fed and dried into the storage chamber (1) is small, the guide plate (8) that guides the grains into the storage chamber (1) can be rotated. Then, in conjunction with this rotating operation, the rotation of the feed valve (2) that feeds out the grains and flows down is controlled to a low speed rotation, thereby reducing the number of times the grains are circulated, thereby preventing damage to the grains. For example, if the dryer is equipped with two or more drying chambers (5), the guide plate (8 ), it is possible to guide and dry grains only to the drying chamber (5) on one side, thereby making it possible to dry a smaller amount of grains.
