Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an improvement to a grain humidity control device and method.

Conventionally, the moisture content of grain is the standard moisture content (14 to 15
It is known that if the moisture content is insufficient (%), water is supplemented to bring the moisture level to the standard level. Temperature treatment is performed by setting up a leaving step, then adding a large amount of moisture at once within a short period of time, allowing long standing time for tempering, and then repeating water addition to perform intermittent intensive humidification. has become the norm. That is, it has become customary to provide a conditioning process that is significantly longer than the humidification process, and to perform humidity conditioning by alternately repeating these two types of processes.

In this way, cracks occur due to the temporary addition of excessive water, and once cracks occur, damaged grains are generated that will not recover no matter how hard they are tempered. In particular, white rice does not have the wax coating that acts as waterproofing like brown rice does, so water from excessive concentrated humidification is rapidly absorbed, causing noticeable cracks due to rapid distention of the intestines. Efficient and safe humidity control is impossible with the so-called tempering method of humidity control, which involves adding an excessive amount of water to the air, resting for a long period of time, then adding water again, and then repeating humidification and leaving it for a long time.

Furthermore, a particularly important condition for grain conditioning is to uniformly humidify the whole grain, but conventional humidity control devices have a defect in that they cannot uniformly humidify the whole grain.

In the present invention, a large number of ventilation gap windows are provided between the front and rear walls with sloped surfaces curved in a zigzag shape, and when the grains flow down the zigzag flow path, they mix well and flow, allowing moisture to flow through the gaps between the grains. A grain humidity control device and method in which a moisture generator is connected to the gap window so as to uniformly humidify the grain through the grain. Further, in this device, wing pieces protruding into and out of the flow path are supported in a gap window on the side of the air supply path, and the air supply path opens to allow wet air to pass through only when grains flow through the flow path.

Therefore, the present invention configures the entire process so as to shorten the useless tempering process and increase the humidity conditioning process as much as possible,
By humidifying a small amount of humidified water as continuously as possible over a long period of time, we have secured the amount of humidification per unit time, so compared to conventional humidification that requires a long tempering process using a humidity control device using a container of the same size. It is a remarkable effect of the present invention that it is possible to perform highly efficient humidity control with an extremely high degree of safety that prevents shell splitting damage compared to other apparatuses, and that the grains are uniformly humidified by the mixed flow in a zigzag stroke. Furthermore, even if the grains supplied to the flow path of the container serving as the humidity control chamber of the present invention are less than the entire internal volume, the on-off valve of the air supply path is closed according to the amount of grain to prevent damp air from blowing through. It also has the effect of providing complete humidity control without air leaks.

To explain the present invention using an example, a humidity control container 1
The front side wall 2 and the rear side wall 3 are formed by alternately erecting fragmentary bent side wall pieces 6 and 7 with inclined surfaces 4 and 5 in a staggered manner, and between each of the side wall pieces 6 and 7, Humid air is passed through the air supply path 8 and exhaust air path 9 provided in the air supply path 10, that is, the humidity control chamber, and the grains are well mixed and flowed down in a zigzag pattern, humidifying all the grains uniformly. 8 is connected to the humidity generator 11. When the container 1 is not filled with grain, the on-off valve 12 rotatably mounted on the front wall 2 is closed by its own weight.
When the grains flow in the flow path 10, the flow piece 13
moves downward, and the on-off valve 12 closes the air supply path 8 to prevent air leakage.

In some cases, a grain hoisting machine 14 is attached to this device, and the same grain is circulated through the flower 10 of the humidity control container 1 multiple times for humidity control.

The present invention can be used not only for brown rice but also for controlling the humidity of white rice for rice and white rice for sake brewing.

In the example diagram, the inclined surface also serves as the inclined surface of the fluidized piece 13.
