(Means for Solving the Problems) In order to achieve the above object, the present invention was constructed as follows.

That is, the present invention heats the outside air taken in from the outside air intake with a heat source, exhausts the heated air to the exhaust chamber via the drying chamber and the drying on/off valve, and also provides a ventilated air vent to the drying chamber. It consists of a drying unit that opens the drying on-off valve when the drying box is inserted and dried, and a plurality of these drying units are arranged and connected by a connecting body, and when connected, each of the adjacent drying units The ventilation chambers are connected to form a common ventilation path.

(Function) In the present invention configured as described above, a plurality of drying units 1 each having a drying function by themselves are arranged and connected by a connecting body such as the connecting frame 2, so that it can meet the user's needs. It is extremely easy to manufacture a dryer with a suitable processing capacity.

Furthermore, when the drying units 1 are connected, the ventilation chambers 6 of the adjacent drying units 1 are connected to form a common ventilation path 15 as shown in FIG. By simply providing one exhaust fan in the air exhaust passage 15, each drying unit 1 can be exhausted.

Further, each drying unit 1 is provided with a drying on-off valve 13, and the drying on-off valve 13 is opened only when the drying box 4 is inserted into the drying chamber 5 of the drying unit 1 to dry the grain sample. As a result, the heater 9 and the suction fan 7 can be driven in response to the drying on-off valve 13.
This makes it possible to contribute to energy conservation.

(Example) Next, an example of the present invention will be described with reference to the drawings.

The embodiment of the present invention has a drying function by itself.
A plurality of box-shaped drying units 1 as shown in FIG. 3 are arranged vertically and horizontally as shown in FIG.
They are interconnected by a connected body consisting of connecting frames 2 as shown by the dashed line in the figure.

As shown in the figure, each drying unit 1 has four positioning holes IA in its upper part and four positioning protrusions IB in its bottom part. As a result, by inserting each protrusion IB of one drying unit 1 into the corresponding positioning hole IA of the other drying unit 1, the re-drying units can be easily connected in the positioned state, so drying in the vertical direction is possible. Connecting the units 1 becomes extremely easy.

Furthermore, as shown in FIG. 1, each drying unit 1 includes a hot air chamber 3 that generates hot air, a drying chamber 5 into which a drying box 4 containing a grain sample is inserted and which dries the grain sample with hot air.
and an exhaust chamber 6 for exhausting hot air exhausted from the drying chamber 5 to the outside.

The hot air chamber 3 has an outside air intake port 8 for taking in outside air with a suction fan 7, and a heater 9 as a heat source for heating the outside air sucked by the suction fan 7 is arranged inside the room.

The drying chamber 5 has a hot air port 1o at its bottom that takes in the hot air from the hot air chamber 3, and an air exhaust port 11 that exhausts the hot air that has been taken in, and the air-permeable drying box 4 can be freely inserted into the room. shall be. The drying box 4 has an open top and a bottom formed with a ventilation plate such as a mesh plate 12.

The air exhaust port 11 of the drying chamber 5 is provided with a drying on-off valve 13 that can open and close the air exhaust port 11 freely.
The link mechanism 14 is connected to the link mechanism 14. This link mechanism 14 is
When the drying box 4 is completely inserted to the back of the drying chamber 5 for drying, a link 14A is pressed at the rear of the drying box 4 to open the drying on-off valve 13. Further, when the drying on-off valve 13 is in the open state, the suction fan 7 and the heater 9 are energized. This makes it possible to save energy.

Openings 16 and 17 are formed on both left and right sides of the exhaust chamber 6, respectively, to form a common exhaust passage 15 as shown in FIG. Therefore, when each drying unit 1-1 is connected as shown in FIG. A path 15 is formed. The terminal ends of these common air passages 15 are connected to form one exhaust port, and an exhaust fan is provided at the exhaust port.

Note that in the four vertical drying units 1 located on the leftmost side as shown in FIG. 4, the opening 17 of the ventilation chamber 6 as shown in FIG. It is assumed that section 17 is not provided.

Next, an example of the operation of the embodiment configured as described below will be described.

Now, when the drying box 4 containing the grain sample is inserted into the drying chamber 5 as shown in FIG.
, the link mechanism 14 operates and the drying on/off valve 1 is pressed.
3 is in the open state and drying is possible.

In response to this, the suction fan 7 and the heater 9 are each energized, so that the outside air taken in from the outside air intake port 8 by the suction fan 7 is heated by the heater 9. After this heated air passes through the grain sample in the drying box 4, it is exhausted into the hot air chamber 6 via the drying on-off valve 13. Further, the exhaust air is exhausted to the outside through the common exhaust passage 15.

After that, when drying of the grain sample is completed and the drying box 4 is taken out from the drying chamber 5, the drying on-off valve 13 is opened, and in response, the suction fan 7 and the heater 9 are de-energized. do.

(Effects of the Invention) As described in ``2'' below, in the present invention, a plurality of drying units each having a drying function are arranged and connected by a connecting body, so that the drying processing capacity can be adjusted according to the user's request. The machine can be manufactured easily and can respond to the user's requests in detail.
