Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a technology for drying materials to be dried in a line using solar heat.

[Prior Art] Conventionally, in industrial or commercial processes, a drying chamber with a dry atmosphere is provided as part of the process in order to dry sheet metal to be coated, laundry, etc. in a short time.

However, these drying chambers use electricity, gas, flammable fuel, etc. as energy sources to raise the indoor atmospheric temperature, and require fuel costs that are approximately proportional to the operating time. This method does not have the above-mentioned drawbacks and dries the material reliably and in a short time like the conventional method, as this has led to an increase in costs due to the recent rise in fuel costs, which in turn leads to higher product costs. There was a desire for a drying device that could do this.

[Object of the Invention] The present invention has been made to meet the above-mentioned needs, and it saves energy for raising the atmospheric temperature in the drying chamber.
Another object of the present invention is to provide a solar drying device that can dry objects to be dried in a short time by keeping the indoor temperature high.

[Configuration of the Invention] In order to achieve the above object, the solar drying device of the present invention has the following configuration: a drying chamber that has a transparent plate on the wall that transmits sunlight and guides the sunlight inside; , a light collecting heat storage means for collecting sunlight transmitted through the transmission plate and accumulating it as heat; a line for guiding the material to be dried into the drying chamber; and a line for preventing leakage of warm air from an entrance/exit of the line into the drying chamber. The gist is to provide leakage prevention measures and the following.

[Embodiment 1] An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows the solar drying apparatus of this embodiment, with (a) showing a front view, (b) a right side view thereof, and (c) a left side view thereof. In the figure, reference numeral 1 denotes a passageway connecting the drying chamber 2 and the outside, which is inclined upward toward the drying chamber as shown in the figure, and also serves as means for preventing the leakage of hot air, as will be described later. The walls of both passage 1 and drying chamber 2 transmit light and thermally shield the inside of passage 1 and drying chamber 2 from the outside. It is composed of a double-layered glass 3 having a heat insulating void layer for insulation. Reference numeral 4 denotes an auxiliary heat collecting device protruding from the drying chamber 2, and 5 indicates an indoor heat collecting device installed on the roof of the drying chamber 2, which is heated by natural convection inside the drying chamber 2 or moves upward by a forced convection device 13 described later. This is a cooling device equipped with a fan to appropriately discharge warm air.

6 is a burner as an auxiliary heating device to enable use of the solar drying apparatus in all weather conditions, and 7 is a ventilation pipe that guides the air warmed by the burner 6 into the drying chamber 2.

FIG. 2 shows a sectional view of FIG. 1 above. Figure 2 (a) shows a cross-sectional view along line AA' in Figure 1, and (1) shows a cross-sectional view along line BB'. The condensing heat storage device 8 includes a reflecting part 8a that reflects light rays, which is made by curving an inexpensive and easy-to-process metal plate such as a zinc plate, and a reflecting part 8a that reflects the rays of light. The heat storage section 8b is formed by enclosing sand, earth, etc. with a large specific heat in a black cylinder to absorb the energy well and store heat. Reference numeral 9 indicates a part of the process of connecting the passage 1 and the drying chamber 2.In one line, the material to be dried 11 is suspended by a hook 10, and the hook 10 is slid along the line 9 by an electric motor (not shown). The material to be dried 11 is guided into the drying chamber 2 through a passage 1, and the material to be dried 11 is reciprocated in the left-right direction in the drawing for a predetermined period of time, and then carried out again through the passage 1 to the outside. Reference numeral 12 denotes an mflJ sensor located above the drying chamber 2 near the center. In FIG. 2 (b), 138 is a part of the forced convection device 13, which has a hollow rectangular parallelepiped shape, and sucks warm air that accumulates upwards due to natural convection inside the drying chamber 2 from its upper opening. This is a ventilation path for sending the drawn warm air into the main body of the forced convection device 13, which extends longitudinally. Forced convection system @13
is in communication with the adjacent blower device 14. This blower device 14 blows out warm air from the ventilation path 13a taken into the forced convection device 13 by the operation of a fan 15 attached to the outside of the drying chamber 2, as shown by the arrow in the figure, and blows out the warm air from the air passage 13a to the drying material.
This is provided so that drying of step 1 can be carried out efficiently. 16 is heated by burner 6! This is an auxiliary convection device that introduces air through the ventilation pipe 7 and guides it to the blower device 14. Also, the surface of the auxiliary heat collecting device 4 is formed of a double glass 3 like the passage 1 and the drying room 2, and the inside thereof is covered with a heat collecting plate 17 placed around the center of the structure as shown in the figure. There is. The heat collecting plate 17 is made of, for example, a metal plate coated black that absorbs sunlight, especially infrared rays, and emits heat. Supportive measures fever in this kind of structure! Since the tray 4 is installed at a lower position than the floor of the drying chamber 2, only the coldest air in the drying chamber 2, that is, the air with the highest specific gravity, is drawn from near the floor of the drying chamber 2 by natural convection. The air is sucked in as shown by the arrow, warmed by the heat of the heat collecting plate 17, and only warm air with a low specific gravity is discharged into the re-drying chamber 2. At step 18, the operator inputs the desired temperature in the drying chamber 2, compares the set temperature from the temperature setting device 19 with the actual temperature information from the sensor 12, and maintains the indoor temperature at a constant level. An electronic III system is shown in which the cooling device 5 or the burner 6 is operated accordingly.

The solar drying apparatus configured as described above efficiently dries the material to be dried 11 as described below.

First, when this solar drying device is illuminated by sunlight, etc., it passes through the glass 3 up to the double TFO and passes through the passage 1, the heat collecting device 8 in the drying room, and the heat collecting plate in the auxiliary heat collecting device 4. 17
effectively converts the irradiated light into thermal energy. At this time, the heat energy in the auxiliary heat collecting device 4 is efficiently transferred to the drying room 2.
Although the heating of the air within the passageway 1 has been described above, a similar effect is produced on the thermal energy within the passageway 1. That is, as shown in FIG. 1(A), the passage 1 has an upward slope toward the drying chamber 2. Therefore, among the warm air in the drying chamber 2, the warm air in the drying chamber 2 whose temperature is higher than that in the drying chamber 2 is guided into the drying chamber 2 by natural convection. Air with a lower temperature than the warm air flows into the passage 1. Therefore, the thermal energy in the drying chamber 2 is always maximized with the aid of the passage 1 and the auxiliary heat collecting device 4. Information on the temperature inside the drying chamber 2 is inputted to the electronic control circuit 18 by a humidity sensor 12 provided in the room, and is inputted in advance to the temperature setting device 19.
The temperature is set to 1 and compared with the temperature desired by the operator. When the temperature in the drying chamber 2 does not reach the set temperature, such as when there is not enough sunlight or when drying at extremely high temperatures, the electronic control device r! 118 operates the burner 6 and the fan 15
Warm air is sent into the drying chamber 2 from the °C blower 14. Then, the temperature inside the drying room 2 changes due to sunlight and the burner 6.''7. ? ? When the temperature matches the set temperature, the burner 6 is stopped and an electric motor (not shown) is activated to guide the material to be dried 11 into the drying chamber along the line 9. At this time, the warm air in the drying chamber rises due to natural convection, and the air vent (because it collects only in the vicinity and may not dry the material to be dried 11 efficiently) is activated, and the forced convection device 13 is used. The warmer air near the ceiling is forcibly moved downwards, and the air blower @14
The warm air is blown onto the material 11 to be dried to improve drying efficiency. When the sunlight becomes stronger and the temperature inside the drying chamber exceeds the set temperature, the electronic control unit 18 operates the fan of the cooling device 5 based on the information from the melon sensor 12, and the drying chamber 2
The air whose temperature has risen the most, that is, the air near the ceiling, is exhausted to the outside, lowering the indoor temperature to the set temperature.

By performing this series of operations appropriately depending on the temperature inside the drying chamber 2, the temperature inside the drying chamber 2 is kept constant at the temperature desired by the operator, and the drying material 11 is passed through the inside of the drying chamber 2 using the line 9. By reciprocating in a predetermined period of time, an efficient and accurate drying process can be achieved.

The structure and effects of one embodiment have been described in detail above, and this solar drying device utilizes sunlight as a heat source. Therefore, it is preferable that the front view shown in Figure 1 (a) faces south, and since it emits more heat energy in proportion to the amount of sunlight, it should be in a place where there are no buildings etc. in the surrounding area and there is no shade. It is preferable that the facility be located at More preferably, the solar drying device is installed on the roof of the building, which increases the amount of sunlight and leads the material to be dried 11 into the drying chamber 2 from a step located at a lower location than the solar drying device. The passageway 1 inevitably has an upward slope toward the drying chamber 2, and as described above, the thermal energy within the passageway 1 can be used effectively.

Next, alternative technologies and other uses of each of the components constituting the solar drying apparatus of the embodiment described above will be explained.

First of all, in this embodiment, the passage 1 has a gradient of (1), and is not simply used as a passage for the material to be dried 11, but is equipped with a condensing heat storage device 8, which has the effect of warming the inside of the drying chamber 2, and It is also equipped with an index prevention means to prevent warm air from overflowing to the outside.However, in cases where the solar drying device is installed at the same height as other processes in line 9 or constantly above the process, passage 1 may be If it is difficult to create an upward slope toward the drying chamber 2, it is possible to install an air curtain or cloth curtain as a means to prevent hot air from leaking. Therefore, it is not necessary to use translucent walls in the passageway 1, since it becomes impossible to introduce the light using natural language/j style.

Next, the double-walled glass 3 is used as a translucent wall surface that has a heat insulating effect. This prevents the generation of water droplets on the glass surface inside the drying chamber 2 caused by the temperature difference between the warm air inside the drying chamber 2 and the outside air, eliminates the negative impact on the material to be dried 11, and has transparency, heat resistance, This was done in consideration of durability.Therefore, the material in step (a) is not limited to glass, but may be an inexpensive material such as vinyl depending on the usage environment and usage temperature of the solar drying device.

The light collecting heat storage rA8 includes the light reflecting section 8a and the heat storage section 81 as described above.
), it is constructed as shown in Fig. 3.

In this example, the arrangement inside the drying chamber is as shown in FIG. The figure shows a schematic perspective view of the floor of the drying chamber 2. In this example, we assume that the first side is facing south, as shown in the front view of Figure 2 (A), which is the most preferable installation method for the solar drying device described above.
The arrangement of the condensing heat storage devices 8 is determined. Therefore, as shown in FIG. 4, most of the condensing heat storage device 8 has its light reflecting portion 8a facing south and C11i! It is placed there. Despite the above-mentioned reason, the light-reflecting part 8a of the condensing heat storage device 8 in the section 4A in the drawing is arranged in the left-right direction in the drawing, that is, in the east and west directions. This is due to the rise in temperature in the drying room 2 of this solar drying device during normal working hours, for example from 8:00 a.m. to 5:00 p.m.
It is adapted to the light incident conditions of the morning sun and the setting sun, taking into consideration the effective use of sunlight between the time frames C. By arranging it in this way, for example, the temperature inside the drying room 2 can be raised considerably at the beginning of the process, and by effectively utilizing sunlight until sunset, the temperature inside the drying room 2 can be maintained for a considerable period of time even after sunset. Can be kept at high humidity. As mentioned in the explanation, it is desirable to change the arrangement method as appropriate in order to make effective use of sunlight, and therefore it is limited to the example shown in Figure 4. The light reflecting section 8a is designed with a degree of freedom so that it can be arranged optimally depending on various conditions such as the season, working hours, and set temperature.The light reflecting section 8a is arranged with the heat storage section 8b as the central axis, and is arranged as shown by the arrow in Fig. 3. As shown in J, it is formed to be freely rotatable, and even after the arrangement of the condensing heat storage device 8 is determined, the light reflecting portion 8a can be appropriately rotated according to the incident angle of sunlight, thereby increasing the non-emission efficiency. It is.

Furthermore, regarding the line 9 for transporting the material to be dried 11 into the drying chamber 2, the material to be dried is not only moved back and forth within the drying chamber 2, but also the material to be dried is moved while moving within the drying chamber 2. 11
Since the sunlight that has passed through the double-layered glass 3 is directly irradiated on the glass 3, techniques such as rotating and moving the object 11 to be dried are used so that all surfaces of the object 11 to be dried are evenly exposed to sunlight. You may use it.

As detailed above, this solar drying device has various degrees of freedom in order to make effective use of sunlight, but no matter which technology is used, the thermal energy used for drying is This reduces fuel costs and eliminates exhaust gas and noise.
Since the drying time can be kept short, exhaust gas and noise are extremely reduced, making it an excellent drying chamber. Moreover, because of its degree of freedom, it is possible to always operate under optimal conditions regardless of facility location or season.

1 Invention of the Song Dynasty] As described with reference to its embodiments, the present invention has a transmitting plate that transmits sunlight, and a light collecting and heat storage means that collects the sunlight that has passed through the transmitting plate and stores it as thermal energy. It forms a drying room. Therefore, in addition to preventing dust etc. from outside from attaching to the items to be dried, ifi with less exhaust gas and noise
'A perfect drying room can be constructed. Moreover, because part of the process line is brought into the drying chamber through a passageway, it can be used under exactly the same conditions as a conventional drying chamber, and there is no increase in the amount of work required. It provides a truly convenient drying room that saves you money.

The gist of this is to provide leakage prevention measures and the following. [Embodiment 1 and subsequent] Examples of the present invention will be described in detail with reference to the drawings. 1 to 3 show the solar drying apparatus of the first embodiment, (a) is its front view, (b) is its right side view, (
C) shows its left side view. In the figure, reference numeral 1 denotes a passage connecting the drying chamber 2 and the outside, which is inclined upward toward the drying chamber as shown in the figure, and which also serves as a means for preventing the leakage of warm air, as will be described later. Both walls are made of double 41IiN glass 3 that transmits light and has a heat insulating void layer for thermally shielding the inside of the passage 1 and the drying chamber 2 from the outside. 4 is an auxiliary heat collecting device protruding from the drying chamber 2; 5 is installed on the roof of the drying chamber 2; the indoor heat collector 5 moves upward by heated natural convection inside the drying chamber 2 or forced convection device 13, which will be described later. It is a cooling iJ1 Wl equipped with a fan to appropriately discharge warm air. Reference numeral 6 indicates a burner as an auxiliary heating device to enable use of the solar drying apparatus in all weather conditions, and reference numeral 7 indicates a ventilation pipe that guides the air warmed by the burner 6 into the drying chamber 2. FIG. 2 shows a sectional view of FIG. 1 above. FIG. 2(A) shows a ΔΔ′ sectional view of FIG. 1, and FIG. 2(B) shows a BB′ sectional view. (a) In the figure, 8 indicates a light condensing heat storage device as a light condensing heat storage means. The condensing heat storage device 8 has a reflecting section 8a that reflects the light beam, which is made by bending a metal plate that is inexpensive and easy to process, such as a zinc plate, and receives the light beam reflected by the reflecting section 8a. It is formed by a heat storage part 81), which is a black cylinder filled with sand, soil, etc. having a large specific heat, and is used to absorb that energy and store heat. 9 is passage 1 and dry; to', room 2, etc. is 3! l! On the line that forms part of the drying process, the object 11 to be dried is suspended by a knock 10, and a hook 10 is slid along the line 9 by an electric motor (not shown), and the object 11 to be dried is dried through the passage 1 from the outside. Lead into v2,
The material to be dried 11 is moved in the left-right direction in the drawing for a predetermined period of time (t): returned to its original position and transported outside through the passage 1 again. Reference numeral 12 denotes a humidity sensor υ located on the negative side of the drying chamber 2 near the medium heat. In Figure 2 (b), 1.38 is the forced convection device H13.
-fllll forms a hollow straight body shape and is placed inside the drying chamber 2a.
This is a ventilation passage for sucking in warm air that accumulates upward due to natural convection through the upper opening and sending the sucked warm air into the main body of the forced convection device 13 that extends longitudinally inside the drying chamber 2. The forced convection device 13 communicates with an adjacent blower device 14 . This air blowing device 14 blows out warm air from the ventilation path "13a" taken into the forced convection device 13 by the operation of a fan 15 attached to the outside of the drying chamber 2, as shown by the arrow in the figure, and Efficiency of drying 11:
< 41 It has been renovated in stages to make it appear. 16 introduces air heated by the barb 6 through the ventilation pipe 7,
This is an auxiliary convection 14tffi that leads to the blower 14. In addition, the auxiliary heat collector @ 4 is a double 4
A heat collecting plate 17 is placed around the inside of the apparatus near the fire, just as in sushi. The heat collecting plate 17 is made of, for example, one roll of polarized metal that absorbs sunlight and especially infrared rays well and emits heat, and is made black by m3L%. 4 like this?
The 4-piece auxiliary heat collecting device 4 is positioned at a lower level than the floor of the drying chamber 2, so natural convection allows only the coldest air in the drying chamber 2, that is, the air with the highest specific gravity, to flow into the drying chamber. Inhale from near the floor of 2 as shown in the arrow, and place each on the heat collecting plate 1.
It works to warm the drying chamber 2 with the amount of heat it has and discharge only the warm air with a small specific gravity into the drying chamber 2 again. ] 8, the operator inputs that he/she wants to set the temperature inside the drying chamber 2 to a desired temperature.The set temperature from the temperature setting device 19 is compared with the actual temperature information from the heat sensor 12. An electronic control device is shown which operates the cooling device 5 or the burner 6 as appropriate. The present solar drying and equipment constructed as described above efficiently dries the J: sea urchin drying material 11 described below. First, when this solar drying device is irradiated with sunlight or the like, it passes through the 2-meter glass structure 3, and the passage 1, the condensing heat storage device 8 in the drying room, and the heat collecting plate 17 in the auxiliary heat collecting device 4 are exposed. The light is effectively converted into thermal energy. At this time, as described above, the heat energy in the auxiliary heat collector Ri & 4 efficiently warms the air in the drying chamber 2, and the heat energy in the passage 1 has a similar effect. That is, as shown in FIG. 1(A), the passage 1 has an upward slope toward the drying chamber 2. Therefore, the warm air in passage 1 is more b than the warm air in dry*IZ2? Items with a low n degree are guided into the drying chamber 2 by natural convection, and conversely, among the warm air in the drying chamber 2, items with lower humidity than the warm air in the passage 1 are guided into the drying chamber 2.
leaks to. Therefore, the thermal energy in the drying chamber 2 is always maximized with the aid of the passage 1 and the auxiliary heat collecting device 4. Information on the temperature inside the drying chamber 2 is inputted to the electronic control circuit 18 by a heating unit 12 provided in the room, and is compared with the temperature desired by the operator, which is set in advance in the temperature setting device 19. When the temperature in the drying chamber 2 does not reach the set temperature, such as when the sunshine hours are less than 4 minutes or when drying is performed at extremely high temperatures, the electronic control unit 18 operates the burner 6 and uses the fan 15 to Warm air is sent into the drying chamber 2 from the blower 14. When the temperature inside the drying chamber 2 rises due to sunlight and the burner 6 and becomes equal to the set temperature, the burner 6 is stopped and an electric motor (not shown) is activated to move the material to be dried 11 into the drying chamber along the line 9. At this time, natural convection causes dryness.
<The warm air in the room rises and accumulates only near the ceiling, which may not dry the items to be dried 11 efficiently, so the fan 15
The forced convection device 113 is used to forcibly move the warmer air near the ceiling downwards, and the blower device 14 blows the warm air onto the material to be dried 1'1 to improve drying efficiency. enhance When the sunlight becomes stronger and the temperature inside the drying chamber exceeds the set temperature, the electronic control unit 18 operates the fan of the cooling device 5 based on the information from the temperature sensor 12, and the temperature inside the drying chamber 2 increases.
The warmest air in the room, that is, the air near the ceiling, is discharged to the outside to lower the indoor temperature to the set temperature. Then, by carrying out the operation of -)f as appropriate depending on the temperature inside the drying chamber 2, the temperature inside the drying chamber 2 will be constant as desired by the operator, and the inside of the drying chamber 2 can be heated using the line 9. If the dried material 11 is allowed to stand for a predetermined period of time, an efficient and accurate drying process can be achieved. The structure and effects of the first embodiment have been described in detail above, and this solar drying device utilizes sunlight as a heat source. Therefore, it is desirable that the front view shown in Figure 1 (a) faces south, and that there are no buildings nearby, since more heat energy is emitted in proportion to the amount of sunlight. It is preferable to install the solar dryer in a place that is not shaded, and more preferably, the solar dryer is installed on the roof of a building. Due to a certain process, the passage 1 that leads the material to be dried 11 into the drying chamber 2 inevitably has an upward slope toward the drying chamber 2, and as described above, the thermal energy in the passage 1 can be used effectively. Next, each of the four components constituting the solar drying apparatus of the Iζ embodiment described above is
Next to the I component, we will explain its alternative technology and how to use Sen. First, in this embodiment, the passage 1 has a slope u1, and is not only used as a passage for the material to be dried 11, but also has the effect of heating the interior of the drying chamber 2 by arranging a condensing heat storage device 8, and the warm air inside the drying chamber 2 is transferred to the outside. It also has leakage prevention means to prevent overflow. However, in cases where the solar drying device is installed at the same height as other processes in line 9 or at Tm from the processes, etc.
When it is difficult to make the passageway 1 slope upward toward the drying chamber 2, an air curtain or a cloth curtain may be provided as a means for preventing leakage of warm air. In this case, the warm air in the passage 1 cannot be properly introduced into the drying chamber 2 using natural convection, so the passage 1 does not necessarily need to have a translucent wall surface. Next, the double-walled glass 3 is used as a translucent wall surface that has a heat insulating effect. This prevents the generation of water droplets on the glass surface inside the drying chamber 2 caused by the temperature difference between the warm air inside the drying chamber 2 and the outside air, and eliminates the negative effect on the material to be dried 11. , with durability in mind. Therefore, the material is not limited to glass, and inexpensive materials such as J, Rijineel, etc. may be used depending on the operating environment and operating temperature of the solar drying device. As described above, the condensing heat storage device 8 is constructed as shown in FIG. 3 by the light reflection section 8a and the heat storage section 8b. In this example, the arrangement inside the drying chamber 1 is configured as shown in FIG. The figure shows a schematic perspective view of the floor of the drying chamber 2. In this example, we assume that one side faces south as shown in the front view of FIG. I have never had an array. Therefore, as shown in FIG. 4, most of the condensing heat storage device 8 is arranged with its light reflection section 8a facing south. For the reason mentioned above, the light reflecting section 8a in the section 4A in the drawing is disposed toward the right, that is, toward the east and west in the drawing. This is done in consideration of making effective use of sunlight during normal working hours, for example from 8:00 a.m. to around 5,200 p.m., to increase the temperature in the drying room 2 of this solar drying device. It is adapted to the light incidence conditions of the setting sun. By arranging it in this way, for example, it is possible to raise the temperature considerably at the beginning of the process, and to utilize the 4I effect of sunlight until sunset. The temperature inside room 2 can be maintained at a high temperature. As mentioned in the explanation, it is desirable to change the arrangement method appropriately in order to make effective use of sunlight. Therefore, the arrangement method is not limited to the example shown in FIG.
i Installation conditions - Various conditions such as season, working hours, temperature setting, etc.1
'1 is designed with a degree of freedom so as to provide an optimal arrangement. The light reflecting section 8a is formed to be rotatable about the heat storage section 8b as the central axis as shown by the arrow in FIG. By appropriately rotating the light reflecting portion 8a, the light collection efficiency can be increased. Furthermore, regarding the line 9 that guides the material to be dried 11 into the drying v2, it not only moves the material to be dried 11 by simply reciprocating within the drying chamber 2, but also transports the material to be dried while moving within the drying chamber 2.
(7) Since the sunlight that has passed through the glass 3 is directly irradiated, the object to be dried 11 must be rotated and moved so that all surfaces of the object 11 to be dried are exposed to sunlight evenly. Even if you use the technology of Next, regarding the second embodiment of the present invention, FIGS. 5(a) and (b)

(A) As shown in the figure, there are many suction holes 113 on its side.
It has C. 114 indicates a wind direction adjusting blower device. Figure (c) shows a schematic perspective view of this wind direction adjusting blower device 114.
io figure L ilj (1' T, 114a is the main body (゛) that becomes one passage, 114b is a long plate-shaped wind direction adjustment plate, and the rotating shaft 114c is set approximately at the center in the axial direction,
The main body 1 is rotatable about the rotating shaft 114C.
A large number of them are arranged at the air outlet of 1/'Ia. In addition, reference numerals 1 to 19 in FIG. 5 are the same as the corresponding components of the first embodiment described above. The solar drying apparatus constructed as described above can apply all the alternative techniques of the first embodiment (a) above, and has all the effects, as well as the following excellent effects. First, the newly installed condensing heat storage device 108 in the passage 1 allows the passage 1 to become even hotter. Therefore,
Due to the natural convection described above, a large amount of heat energy is supplied into the drying chamber 2, and the material to be dried 11 can be dried efficiently. Next, since the forced convection heating device 118 has a heating ventilation passage 113a, instead of simply performing forced convection inside the drying chamber 2, the inside of the heating ventilation passage 113a warmed by sunlight is directed upward inside the drying chamber 2. 4i1direct-3 warm air is sucked in and is further heated by this heating ventilation passage 113a itself while moving downward. Therefore, the warm air discharged from the wind direction adjustment sending device 114 has a higher temperature, and the drying efficiency can be improved. In addition, since the inlet of this forced convection heating device 113 is the suction hole 113G provided in the suction passage 113b, it is possible to draw the warm air accumulated on the ceiling of the drying chamber 2 into the forced convection flow without leaking. . Furthermore, the wind direction Kl'J part 3A wind equipment 114 blows the n1 air with increased thermal efficiency onto the material to be dried 11.
A wind direction adjustment plate 114b is arranged at the warm air outlet. For this reason, the shape of the material to be dried 11? 2. By changing the direction of the warm air blowing out to the place where heat is needed by drying, it becomes possible to use highly thermally efficient warm air for drying. The solar drying device described in detail above has various degrees of freedom in order to effectively utilize sunlight.
Regardless of which technology is used, the thermal energy used for drying can be obtained from the natural sun, resulting in fuel cost savings, no noise, and no need for auxiliary heating equipment. As for the equipment provided, since the usage time of the heating 1 can be kept short, exhaust gas and lli noise are reduced in the 11th stage, making it an excellent drying chamber. However, because of this degree of freedom, it is possible to operate the facility under optimal conditions regardless of location or season. [Effects of the Invention] As described with reference to the embodiments, the present invention includes a transmitting plate that transmits sunlight, and a light collecting and heat storage means that collects the sunlight transmitted through the transmitting plate and stores it as thermal energy. A drying chamber is formed by the drying chamber. Therefore, not only can dust from the outside be prevented from adhering to the dried material, but also a clean drying chamber with less exhaust gas and M noise can be constructed. Moreover, because a part of the line for one culm is introduced into the drying chamber through a passage, it can be used under conditions completely different from those of conventional drying chambers, resulting in no increase in work and fuel costs. This saves money and provides a very convenient drying room. 4.
