Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a solar drying device that mainly uses solar heat to dry rice, vegetables, etc.

(Prior Art) Conventionally, various types of drying apparatuses have been proposed for drying rice, vegetables, etc., such as those that heat with a heavy oil burner and those that heat with an electric heater.

(Problem to be solved by the invention) However, in the conventional drying device described above,
Since it uses heavy oil and electricity, there was a problem in that it was disadvantageous in terms of cost because fuel and electricity were required.

The present invention focuses on the above-mentioned conventional problems and aims to provide a solar drying device that uses solar heat to eliminate the burden of fuel costs and to perform efficient drying.

(Means for Solving the Problems) In order to solve the above problems, the solar dryer of the present invention includes a primary dryer and a secondary dryer in a building whose roof and walls are made of double glass plates. The primary dryer is provided with a stirring blade that rotates in the drying chamber, and the secondary dryer is provided with an irradiation member for irradiating sunlight toward the drying chamber, Further, a hot air passage is formed for blowing the air heated by sunlight inside the double glass plate through the drying chamber of the secondary dryer and into the drying chamber of the primary dryer. .

(Function) In the solar drying device of the present invention, the air heated by sunlight inside the double glass plate reaches the drying chamber of the secondary dryer through the hot air duct, and then from there to the drying chamber of the secondary dryer. Air is blown into the drying chamber of the dryer, and the objects to be dried stored in the drying chamber of the secondary dryer and the drying chamber of the primary dryer are dried by this warm air.

At this time, in the secondary dryer, sunlight is irradiated toward the drying chamber by the irradiation member, so that drying can be performed using both hot air and sunlight.

Further, the material to be dried stored in the drying chamber of the primary dryer is dried by hot air while being stirred by a stirring blade.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the entire solar drying apparatus according to an embodiment of the present invention.

The solar drying device of this embodiment includes a double glass plate 1
A building 1 in which a roof and walls are formed in 0, and the building 1
It is equipped with a primary dryer 2 and a secondary dryer 3 arranged inside the dryer.

The double glass plate 10 of the building 1 maintains an air space 13 between the outer glass plate 11 and the inner glass plate 12, and communicates with the air space 13 at the bottom of the wall formed by the double glass plate 10. At the same time, an air intake port 15 is formed in the roof formed by the double glass plate 10, and between the wall and the roof formed by the double glass plate 10, They are communicated through a communication port 16.

The primary dryer 2 has a cylindrical drying chamber 20 with an input port 21 at the top thereof, and
An outlet 22 for taking out the material to be dried is provided at the bottom of the drying chamber 20, and a pipe shaft 24 in which a number of ventilation holes 23 are formed is pivotally supported in the center.
A stirring blade 25 is attached to the stirring blade 25.
is rotated within the drying chamber 20 by the rotation of the pipe shaft 24 by the motor 26.

The secondary dryer 3 is a box-shaped drying chamber 30.
Inside the drying chamber 30, a rail 32 for placing a pallet 31 is laid, and in the upper part of the drying chamber 30, a large number of convex lenses 33 which serve as sunlight irradiation members and a reflecting mirror 34 are installed.
and a reflecting plate 35 are provided. Note that the convex lens 33 is provided with a lens distance adjusting means,
Further, the reflecting mirror 34 and the reflecting plate 35 are provided with angle adjusting means.

Then, the air heated by sunlight in the air layer 13 of the double glass plate 10 is passed through the drying chamber 30 of the secondary dryer 3 to the drying chamber 20 of the primary dryer 2.
A hot air blowing path 4 is formed for blowing air to.

In this hot air blowing path 4, the air outlet 15 of the double glass plate 10 and the drying chamber 30 of the secondary dryer 3 are connected by a blower pipe 41 provided with a blower 40, and the secondary dryer 3 drying chamber 30 and primary dryer 2
The lower end of the pipe shaft 24 is connected to the blower pipe 42 , and the upper end of the pipe shaft 24 is connected to an exhaust pipe 43 , and an exhaust port 44 at the tip of the exhaust pipe 43 is provided outside the building 1 .

Next, the operation of the embodiment will be explained.

In the solar drying device of this embodiment, the air warmed by sunlight in the air layer 13 of the double glass plate 10 is forced into the air pipe 41 by the blower 40.
The air passes through to the drying chamber 30 of the secondary dryer 3, and from there it passes through the air pipe 42, enters the pipe shaft 24 of the primary dryer 2, is blown into the drying chamber 20 through the ventilation hole 23, and finally is exhausted. It is discharged to the outside of the building 1 from the exhaust port 44 at the tip of the pipe 43.

The hot air passing through the hot air blowing path 4 causes the drying chamber 30 of the secondary dryer 3 and the primary dryer 2 to
In this case, the drying chamber 20 of the primary dryer 2 stores undried materials (for example, paddy), and the drying chamber 20 of the In the drying chamber 30 of No. 3, the materials to be dried that have been primarily dried are stored in pallets 31 and placed on rails 32.

At this time, in the drying chamber 30 of the secondary dryer 3, a large number of convex lenses 33 serving as irradiation members and a reflecting mirror 34 are installed.
Since sunlight is irradiated onto the object to be dried by the reflecting plate 35, the object to be dried can be dried with both warm air and solar heat.

Further, the material to be dried stored in the drying chamber 20 of the primary dryer 2 is sufficiently stirred by the stirring blade 25 and dried by hot air.

(Effects of the invention) As explained above, according to the solar drying device of the invention, the primary dryer uses hot air obtained from solar heat as a heating source, and the secondary dryer uses hot air obtained from solar heat and solar heat as a heating source. Since the drying process uses direct heat from the sun, the heating source is only solar heat, which eliminates the burden of fuel costs and is advantageous in terms of cost.

Moreover, the secondary dryer equipped with the irradiation member and the primary dryer equipped with the stirring blade provide the effect of efficient drying.
