Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The dryer of the present invention receives grain from each producer,
It is applied to a grain drying and preparation facility that is shipped through the processes of drying, selecting, and storing. A part of the grain received at the grain drying and preparing facility is sampled as a sample for voluntary inspection and dried by the grain sample dryer of the present invention.

(Prior Art) Conventionally, as a dryer of this type, a plurality of drying chambers are arranged vertically and horizontally, and a sample storage box containing a grain sample is stored in each of the drying chambers, and the grain sample is dried with hot air. Things are known.

(Problems to be Solved by the Invention) By the way, the scale of the dryer required by the facility, that is, the number of grain samples that can be dried at one time varies depending on the scale of the grain drying and preparation facility to which the dryer is applied.

However, in the conventional dryer, since the drying chambers are integrally connected, the scale of the dryer cannot be changed according to the request of the user's facility, and the user's request can be carefully controlled. There was a problem that could not be dealt with.

Therefore, in order to solve the problem, the present invention makes it possible to easily manufacture a dryer having a desired processing capacity, and an object thereof is to provide a unit-type grain sample dryer capable of finely coping with a user's request. And

(Means for Solving Problems) In order to achieve such an object, the present invention has the following configuration.

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 air exhaust chamber through the drying chamber and the drying on-off valve, and at the same time, the air is permeable to the drying chamber. It consists of a drying unit that opens the on-off valve for drying when the drying box is inserted and dried, and a plurality of drying units are arranged and connected by a connecting body,
At the time of the connection, the air exhaust chambers of the drying units adjacent to each other are connected to form a common air exhaust passage.

(Operation) In the present invention configured as described above, a plurality of drying units 1 having a drying function by themselves are arranged and connected by a connecting body such as a connecting frame 2. It is very easy to manufacture a dryer with a suitable processing capacity.

Further, when the drying units 1 are connected to each other, as shown in FIG. 4, the exhaust chambers 6 of the drying units 1 adjacent to each other are connected to form the common exhaust passage 15. The exhaust of each drying unit 1 can be performed by providing only one exhaust fan in the exhaust passage of the passage 15.

Further, each drying unit 1 is provided with a drying on-off valve 13, and when the drying box 4 is inserted into the drying chamber 5 of the drying unit 1 to dry the grain sample, the drying on-off valve 13 is opened only for the first time. Since this is done, the heater 9 and the suction fan 7 can be driven in response to the drying on-off valve 13, which can contribute to energy saving.

(Example) Next, the Example of this invention is described with reference to drawings.

In the embodiment of the present invention, a plurality of box-shaped drying units 1 each having a drying function as shown in FIGS. 1 to 3 are vertically and horizontally arranged according to the scale of the dryer as shown in FIG. In addition to being arrayed, the arrayed assembly of drying units 1 is connected to each other by a connecting body composed of a connecting frame 2 as shown by the alternate long and short dash line in FIG.

As shown in the drawing, each drying unit 1 has four positioning holes 1A at the top thereof and four positioning protrusions 1B at the bottom thereof. As a result, one of the drying units 1
By inserting each protrusion 1B in each of the corresponding positioning holes 1A of the other drying unit 1, both drying units can be easily connected in the positioned state, so that it is extremely easy to connect the drying unit 1 in the vertical direction. Become.

Further, each drying unit 1 has a hot air chamber 3 for generating hot air and a drying box 4 containing a grain sample as shown in FIG.
And a wind exhaust chamber 6 for exhausting the hot air exhausted from the dry chamber 5 to the outside.

The hot air chamber 3 is provided with an outside air inlet 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 outlet 10 for taking in hot air from the hot air chamber 3 at the bottom thereof, and an exhaust outlet 11 for exhausting the hot air taken in, and the air-permeable drying box 4 can be freely inserted into the interior. And The drying box 4 has an open top and a bottom formed of a ventilation plate such as a mesh plate 12.

An air outlet 11 of the drying chamber 5 is provided with a drying on-off valve 13 that allows the air outlet 11 to be opened and closed, and a link mechanism 14 is connected to the drying on-off valve 13. The link mechanism 14 is configured such that when the drying box 4 is completely inserted into the drying chamber 5 for drying, the link 14A is pushed at the rear part of the drying box 4 to open and close the drying on-off valve 1.
3 is opened. Further, the suction fan 7 and the heater 9 are energized when the drying on-off valve 13 is open. Thereby, energy saving can be achieved.

Openings 16 and 17 are formed on both left and right sides of the exhaust chamber 6 to form a common exhaust passage 15 as shown in FIG. Therefore, when the drying units 1 are connected as shown in FIG. 4, the exhaust chambers 6 of the adjacent drying units 1 are connected to each other, and the connected exhaust chambers 6 are connected to each other.
To form a common exhaust path 15. Then, the ends of these common exhaust paths 15 are connected to form one exhaust port,
An exhaust fan is installed at the exhaust port.

As shown in FIG. 4, the four leftmost drying units 1 in the vertical direction do not require the opening 17 of the exhaust chamber 6 as shown in FIG. The part 17 is not provided.

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

Now, when the drying box 4 containing the grain sample is inserted into the drying chamber 5 as shown in FIG. 1 and further inserted further than the state shown in the drawing, the rear portion of the drying chamber 5 is linked to the link 14A.
Since is pressed, the link mechanism 14 is activated and the opening / closing valve 13 for drying is opened to enable drying.

In response to this, the suction fan 7 and the heater 9 are each energized, so the outside air intake 8
The outside air taken in from is heated by the heater 9. After passing through the grain sample in the drying box 4, the heated air is exhausted to the hot air chamber 6 via the opening / closing valve 13 for drying. Further, the exhaust air is exhausted to the outside through the common exhaust passage 15.

After that, when the drying of the grain sample is completed and the drying box 4 is extracted from the drying chamber 5, the opening / closing valve 13 for drying is opened, and in response to this, the energization of the suction fan 7 and the heater 9 is stopped. To do.

(Effects of the Invention) As described above, in the present invention, since a plurality of drying units having a drying function per se are arranged and connected by a connecting body, a dryer having a processing capacity according to a user's request can be provided. It can be easily manufactured, and thus can meet the needs of users in detail.

Further, in the present invention, since the common exhaust path is formed when the drying units are connected, it is only necessary to provide a common exhaust fan at the exhaust port of the common exhaust path, and the configuration is simple and the manufacturing cost is low. Can be reduced.

Further, since each drying unit has the same configuration and can be mass-produced, the manufacturing cost of the entire dryer can be reduced.
