Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for drying French incense sticks using a heat pump type dehumidifying dryer.

[0002]

2. Description of the Related Art Conventionally, a drying apparatus using a heat pump type dehumidifying dryer is disclosed in Japanese Utility Model Publication No. Sho 51-3482 and Japanese Patent Publication No. Sho 60-2.
2268 has been proposed.

[0003] In the former application, a drying shelf on which a material to be dried is placed is placed in a drying chamber on a trolley, and conditioned drying air discharged from a heat pump type dehumidifying dryer is installed through a partition wall in the drying chamber. This is a technique that forced air is circulated by a forced circulation blower to increase the air volume and eliminate drying unevenness.

[0004] The latter application is a technique in which a net conveyor installed in a drying chamber is divided by a partition wall, and a forced circulation blower is arranged in each of them to increase the air volume to increase the drying efficiency.

[0005]

As described in detail in the above-mentioned application, a heat pump type dehumidifier / dryer cools and dehumidifies air by an evaporator of a refrigerating apparatus, and then sends dry air heated by a condenser to a blower. , And the material to be dried in the drying chamber is dehumidified and dried. Therefore, the drying temperature can be made much lower (20 to 40 ° C.) as compared with the hot air dryer. For this reason, it is suitable for drying materials that easily change in quality under high temperature, and also dry at low temperature in a closed drying room without introducing outside air or exhausting air in the drying room,
Materials that emit an off-flavor when dried at high temperature do not emit off-flavor to the outside air, and materials containing a perfume such as incense sticks are not scattered or deteriorated, and are therefore preferable and sanitary. In addition, the heat pump type dehumidifying dryer has a higher dehumidifying ability than the hot air dryer in terms of the dehumidifying capacity of unit weight air, and has excellent drying capacity for the same air volume. For example, air sent to a drying room by a blower is 11.5 ° C. by an evaporator.
After being cooled to 35 ° C. by a condenser, the wet bulb was heated to 35 ° C.
When moisture is absorbed at ° C, about 6 gr of water is absorbed per kg of air. On the other hand, in a hot-air dryer, for example, when the outside air temperature is 22.6 ° C. and the humidity is 80%, which are average outside air conditions, when absorbing moisture under a wet bulb temperature of 20 ° C., about 1.3 gr water per kg of air is obtained. Has only the ability to absorb

[0006] However, it is generally known that the drying speed increases in proportion to the air volume (or air speed), and that the drying efficiency is improved. However, in a heat pump type dehumidifying dryer, the air speed passing through an evaporator and a condenser is limited. Due to the principle of the refrigeration cycle, it is limited to a low speed of 0.25 m / sec, and its drying capacity is limited because it is about 1/10 of that of a hot air dryer. In this regard, in the hot-air dryer, the drying capacity can be increased in proportion to the air volume because there is generally no limitation on the amount of air blown. As a result, the hot-air dryer has a heat pump type dehumidifying dryer. The drying ability is better than that. For that reason, hot air dryers have been used for drying incense sticks.
As described above, there is a problem that the fragrance is scattered during drying, or an unpleasant odor is generated due to introduction and exhaust of the outside air,
There were many problems such as warping when dried at high temperature.

Further, the heat pump type dehumidifying dryer has too little air flow, so that the air flow is deviated, and the air does not sufficiently contact the object to be dried, causing uneven drying or poor drying. Conventionally, the volume of the drying chamber has been reduced, the amount of processing has been reduced, or a circulating blower has been attached to the wall of the drying chamber to increase the air volume.

The above-mentioned Japanese Utility Model Publication No. 51-3482 and Japanese Patent Publication No. Sho 6
No. 0-22268 has been proposed to solve these problems, but the former can be used for drying incense sticks, but the flow of dry air is one-way for incense sticks placed on a cart. Causes uneven drying. If you try to eliminate drying unevenness, frequently change the direction and location of the trolley during drying,
Since it is necessary to take measures such as changing the top and bottom of the drying plates stacked on the trolley, a skilled person is required, which is troublesome and reduces work efficiency. In the latter, drying of the incense stick is impossible in its structure.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a heat pump type dehumidifying / drying device for incense sticks having high drying efficiency by using a heat pump type dehumidifying / drying device to eliminate uneven drying of incense sticks. It is intended to provide.

[0010]

The heat pump type dehumidifying / drying apparatus for incense sticks according to the present invention has a heat pump type dehumidifying / drying machine arranged on one side of a drying chamber closed by a heat insulating wall, and a duct is connected to the outlet. , With the outlet facing the other side of the drying room, and attaching a humidified air blower to this outlet,
The required number of drying units in the drying chamber, including a frame having an opening around it, a forced circulation blower attached to the top of the frame, and a trolley on which drying plates on which incense sticks are placed so as to close the opening, are stacked. Place and configure.

Further, the rotation direction of the forced circulation blower attached to the drying unit can be manually or automatically switched between forward and reverse.

The drying plate may be made of wood, such as cypress wood, but a cardboard drying plate is preferred because it is rich in hygroscopicity and air permeability. . In addition, the shape of the duct is not particularly limited, or the drying room has a double ceiling,
It may be configured so that the humidified air blown from the heat pump type dehumidifying dryer disposed on one side of the drying chamber is blown to the opposite side of the drying chamber by branching to the left and right sides of the drying chamber.

Further, the frame of the drying unit may be fixed or movable.

Further, the number of openings of the drying unit is preferably provided on four sides of the frame to make it compact and easy to manufacture. However, it is possible to arbitrarily determine only one location or six locations depending on the use situation. it can.

[0015]

The operation will be described. The drying plate on which the incense extruded and cut to a certain length is placed on a carriage and arranged so as to close the opening formed around the drying unit.

Next, the heat pump type dehumidifier / dryer, the humidified air blower, and the forced circulation blower of the drying unit are turned on. The dry air conditioned by the heat pump type dehumidifying dryer passes through a duct and is blown out of the outlet to the opposite side of the drying chamber while being assisted by a humidified air blower. The air volume of the drying air is increased by a forced circulation blower of the drying unit, and is forcedly circulated from one side of the drying plate to the other in contact with the incense to remove moisture from the incense. The relatively high-temperature dry air contains a large amount of moisture taken from the incense stick, becomes low-temperature, high-humidity air, and is sucked into the heat pump type dehumidifying dryer. Here again, the air is dehumidified and dried to form high-temperature, low-humidity dry air, which is sent back into the drying chamber. During drying, the rotation direction of the forced circulation blower of the drying unit is reversed manually or by timer control. After the required time has elapsed, the incense sticks on the drying plate are evenly dried and finished.

The finished incense stick is taken out of the drying room with the cart. Then, the incense stick newly loaded on the cart is charged into the drying chamber in the same procedure as described above.

Depending on the amount of incense to be charged into the drying chamber, it is possible to improve the working efficiency if the incense is produced and prepared in the daytime, charged in the drying chamber in the evening, and taken out the next morning.

[0019]

[0022]

Since the present invention is configured as described above, it has the following effects.

In order to prevent short-circuiting of the conditioned air from the heat pump type dehumidifying dryer, it is drawn into the opposite side of the drying chamber via a duct connected to the outlet thereof, and the wind speed is increased by the forced circulation blower of the drying unit. Because I increased the amount
Dry air could be used effectively and drying efficiency was greatly improved.

Further, since the drying air is constantly brought into circulating contact with the incense by the forced circulation blower of the drying unit, a large amount of moisture is deprived from the incense, and this is sucked into the heat pump type dehumidifying dryer, so that the drying efficiency is improved. .

Further, by controlling the forced circulation blower to rotate forward and reverse, the dry air can be brought into contact with the entire incense stick, so that a high quality incense stick with no drying unevenness can be obtained.

Furthermore, the incense sticks can be charged and unloaded all with a trolley. Even if the direction of the trolley is not changed in the course of drying and the top and bottom of the drying plate is not changed, once the incense has been dried until it is finished. Since it can be left as it is, work efficiency has been improved and labor has been saved.
