By the way, in conventional sample grain dryers of this type, a plurality of drying boxes are inserted and inserted into a dryer frame that is long in the horizontal direction. Therefore, the installation area is inevitably large, and there is a problem that the installation is not easy unless the self-inspection room has a large area, or the construction cost of the independence inspection room becomes expensive.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a drying housing in which a large number of sample boxes can be freely inserted and removed so as to be vertically inserted. Not only to reduce the installation area and facilitate installation in the voluntary verification room,
An object of the present invention is to provide a sample grain dryer that can easily achieve cost reduction and uniform drying of sample grains.

[0005]

In order to achieve the above object, a sample grain dryer according to the present invention has a drying chamber which is long in a vertical direction, a drying chamber at a front side and a hot air generating chamber at a rear side. In the drying chamber , a large number of samples are formed.
The fitting part of the box is provided in multi-tiered upper and lower sides, and hot air blows on both sides
Section and the exhaust section are formed separately, and each of the fitting sections is formed.
Shows a sample box with a ventilation surface on the bottom and an open top.
It is designed to be able to be inserted and removed freely, and the fitting position of the sample box is
The lower side is a hot air supply passage leading to the hot air blower, and
Side as an exhaust path leading to the exhaust section,
The raw room and the hot-air blower are communicated with each other through a blower window at the lowermost portion, and a dust suction device is connected to the uppermost portion of the exhaust passage .

[0006] The sample box is formed in a rectangular cross section whose width is larger than its height when viewed from the front.

[0007]

[Function] A part of multiple types of cereals brought in by individuals or consignees is dried to a certain finish moisture under the same conditions, and the distribution of the producer's selling price is allocated according to the cereal share. in order to obtain a sample grain to accurately perform, first, personalized or consignment to extract a portion of different grain types brought by human, which sample grain and without, it the The sample boxes are housed in a sample box, and then these sample boxes are sequentially inserted in a vertical direction into a fitting portion provided at the center of the front side of the drying housing. Then , when the dust suction device and the heat source body disposed in the hot air generation room on the rear side are operated, the outside air sucked into the hot air generation room by the suction action of the dust suction device is heated by the heat source body and the dry hot air of the appropriate temperature is heated. After being sucked into the hot air blowing section on the front side from the blow window, it passes through the hot air supply path, passes through the grain layer in the drying box, exits from the exhaust path to the exhaust section, and finally absorbs dust. It is sucked by the machine and circulated so as to be exhausted outside the drying casing.

[0008] Then, the sample grains in the plurality of sample boxes that have been sequentially fitted along the vertical direction are dried by the dry hot air flowing as described above. When the sample grain reaches a predetermined finish moisture (for example, 14.5%) by the drying operation, the operation of the dust suction device and the heat source is stopped, and the sample box containing the dried sample grain is pulled out to dry the sample grain. Grain can be processed.

By the way, during the drying operation as described above, the grains stored in the plurality of sample boxes respectively are:
Depending on the type, some are dried quickly to the specified moisture, while others are not easily dried to the specified moisture.
And processing is pulled out from the insert portion, it should insert the insert portion of the sample box remains in the state there is no sample grain.

However, since the sample box is formed in a rectangular cross section whose width is longer than its height when viewed from the front, the deposited layer of the stored sample grains is low and the ventilation resistance is low. Because of this setting, the difference in ventilation resistance between the sample box not containing the sample grains is reduced, and even if the sample box not containing the sample grains is directly fitted into the fitting section, the total The sample grains can be dried uniformly by making the amount of hot air flowing through all of the sample boxes substantially the same.
