Description

[Detailed description of the invention] The present invention relates to improvements in grain sample drying equipment.

Conventional sample drying equipment has multiple opening/closing windows equipped with switching shutters on the upper wall of a box-shaped machine frame containing a built-in hot air generator, and a sample container box with a bottom wall made of breathable material. The sample grains are placed on top of each of the opening/closing windows, and hot drying air is jetted through the opening/closing windows to dry the sample grains, so that dust and light foreign matter mixed in the sample grains (paddy) are scattered around. In addition, the device structure was complicated, maintenance was not easy, and it was difficult to see the opening and closing status of the switching shutter from the outside. The problem was that the hot air generator had to be operated without any operation, leading to malfunctions.

The object of the present invention is to provide a grain sample drying device that eliminates the above-mentioned drawbacks.

Hereinafter, the present invention will be explained with reference to embodiment figures. Reference numeral 1 denotes a rectangular drying machine frame, in which a drying shelf 2 is mounted, a heat generator 3 is provided on one side of the machine frame 1, and an exhaust fan 4 is provided on the other side. ,
A plurality of opening windows 6 are provided on the front side wall 5 of the drying machine frame 1.
A storage container 7 is provided in each opening window 6 to be inserted into and placed on the drying shelf 2, and a bottom wall surface 9 made of wire mesh or the like having a ventilation hole 8 is provided. A drying box 11 for accommodating objects to be dried is provided and has side wall surfaces 10A..., 10B having approximately the same outer circumferential shape as the bottom wall surface 9.
are placed in the openings 12, 12 provided in the bottom wall of the container 7 so as to be removable, respectively, and each storage container 7 with a drying box 11, 11 placed thereon is provided on the front side wall 5. Insert each opening window 6... into each opening window 6...
The lid portion 13 is pressed so as to come into close contact with the front side wall 5 to seal the inside of the machine frame 1. 14
15 is a handle provided on the drying box; 16 is an upper air passage in the machine frame 1;
17 is also a lower air passage.

With the above configuration, a predetermined amount of sample grain is put into each drying box 11, and the bottom wall surface 9 of the box 11 is fitted into the opening 12 of each storage container 7 in an airtight manner. Each container 7 is placed on top of the dryer frame 1, and each container 7 is inserted into each opening window 6 of the front side wall 5, and the lid 13 is pressed to be crimped to the side wall 5, thereby sealing the inside of the dryer frame 1. When the heat generator 3 and the exhaust fan 4 of the device are activated, air at a predetermined temperature generated by the heat generator 3 by the suction force of the exhaust fan 4 flows from the upper air passage 16 to each drying box 11... The grains pass through the lower air passage 17 and are discharged to the outside of the machine frame 1, and the grains in each drying box 11 are dried and adjusted to a predetermined moisture content. In the above sample drying process, the drying box 11 to which sample grains are not supplied
If there is, in the conventional device, the switching shutter provided on the open window on which the empty box is placed is operated to close it, and the ventilation surface of the bottom wall of each box is cut off for drying. Since it is difficult to see the open/closed state from the outside, the drying process is carried out with the ventilation surface of the drying box open, which often results in poorly dried sample grains. In the present invention,
At the beginning of drying, each of the drying boxes 11 is turned sideways or turned upside down, and the opening window 6 at the bottom is sealed to shut off the hot air so that the hot air does not leak. The bottom wall surface 9 is airtightly fitted and placed in the opening 12 provided in the container 7, and the storage container 7 is inserted into the opening window 6, and the lid body 13 is pressed to close the machine frame. Since the interior of the drying apparatus 1 is sealed, sample grains having a predetermined moisture content can always be reliably and easily dried and tempered without producing the sample grains with insufficient drying as described above.

Therefore, there is no need to provide a switching shutter unlike in the past, and the opening and closing of the opening is reliable depending on the presence or absence of a grain sample, without scattering dust or light foreign matter and deteriorating the working environment. can be done,
Furthermore, by transporting the storage container 7, it becomes possible to move multiple drying boxes at once, which facilitates the work of collecting sample grains, simplifies maintenance, and ensures smooth mass production of always high-quality sample dry grains. It has the following effects:
