Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is a method for drying incense sticks in which semi-dry incense sticks arranged and placed on drying plates stacked in multiple stages are dried using dry warm air. It is related to the method.

(Prior art) As shown in Fig. 9, the conventional method for drying incense sticks involves arranging incense sticks B containing moisture after forming incense sticks on a wooden incense stick drying board A, and then placing the incense sticks at intervals. It consists of a drying preparation process in which the incense sticks are stacked in multiple stages, and a drying process in which they are naturally dried.In this natural drying process, the water evaporates and the diameter of the incense sticks becomes smaller, creating a gap between the incense sticks. This is the so-called "board bending work" that closes the gaps between the bumps and prevents distortion.
As shown in Figure 10, when the incense sticks are almost dry, the so-called ``board removal work'' is carried out, which involves inserting the incense sticks between drying plates to suppress and correct the tendency of the incense sticks to warp. The characteristic natural drying method and the preparation for drying are as shown in Figure 9, where the moistened incense sticks B are laid flat on a wooden incense stick drying plate A, and then the incense sticks are stacked in multiple tiers at intervals. process, and a forced drying process that supplies warm air at a predetermined temperature and humidity.In the forced drying process,
Similar to the above-mentioned natural drying method, a forced drying method that is characterized by performing "board bending work" and "board removal work" has been practiced and is well known.

(Problems to be Solved by the Invention) However, the known natural drying method is dependent on the climate, and the incense sticks with a diameter of 2 mm are dried with a moisture content of 10%.
It takes 7 to 10 days to dry to a certain extent, and the diameter is 4.5 mm.
Incense sticks not only take a long time (more than 14 days) to dry, but also require a large space to dry. In addition, wooden incense stick drying boards are expensive and difficult to dry for different incense sticks because of the transfer of scent. We prepare a large number of incense sticks to correspond to the types of incense sticks that cannot be used in common and are to be dried.
The problem was that it had to be stored in a way that it would not be deformed.

In addition, compared to natural drying method, forced drying method is
It has the advantage of being able to shorten the drying time without being affected by the climate, but like the natural drying method, the drying process must be done straight, unless you do the work of bending the board and removing the board, which are difficult and cumbersome to work at the timing of the drying process. There were problems in that it was not possible to obtain incense sticks, and that a large number of wooden incense stick drying boards had to be prepared and stored.

The present invention provides the advantages of a forced drying method, and
To provide a method for drying incense sticks that can economically obtain straight incense sticks without having to perform troublesome work of folding the board and removing the board during the drying process, and without preparing and storing a large number of expensive wooden incense stick drying boards. It is intended to.

(Means for Solving the Problems) In the method of drying incense sticks of the present invention, a hygroscopic material is used on the upper and lower surfaces of a corrugated plate 3 in which convex stripes 1 and concave stripes 2 having a semicircular cross section are alternately formed. A large number of ventilation passages 6 are formed between the upper plate 4 and the lower plate 5 by bonding the upper plate 4 and the lower plate 5.
At least one layer of semi-dry incense sticks 8 is arranged and placed in the same direction as the ventilation passages 6 on the cardboard board 7 which has been formed. Another corrugated board was stacked on the upper layer to form a ventilation passage opening on one side thereof, and a blower 11 was connected to the ventilation passage opening while a predetermined load was applied from above the top plate 4 of the uppermost tier. After the items are carried into a drying room maintained at approximately 30°C to 35°C and humidity of around 50% by dehumidifying means and heating means, room air is forced into the ventilation passage from the opening surface of the ventilation passage using the blower 11. It is characterized by supplying

(Function) According to the method of the present invention, in order to sandwich the semi-dry incense stick 8 between the corrugated cardboard plates 7 in a loaded state, the upper and lower surfaces of the semi-dry incense stick 8 are the hygroscopic upper plate 4 of the corrugated cardboard plate 7, In contact with the lower plate 5, the moisture of the semi-dry incense stick 8 is absorbed evenly by the upper plate 4 and the lower plate 5 under the same conditions, and the warm air supplied from the blower 11 is transferred to the cardboard plate. 7, the ventilation passage 6 of the corrugated plate 3, the adjacent incense sticks 8, 8 arranged in parallel without any gaps, and the gap hole 1 formed in the upper plate 4 and lower plate 5.
4 and 14, the corrugated board 7
At the same time, the moisture infiltrated into the upper plate 4 and the lower plate 5 is dehumidified, and at the same time, the incense stick is uniformly dehumidified and dried from around the surface.

(Example) An example of the method of the present invention will be described with reference to the drawings. As shown in FIG. A corrugated board 7 is used, on the lower surface of which an upper plate 4 and a lower plate 5 made of a hygroscopic material are bonded to form a ventilation passage 6 between the upper plate 4 and the lower plate 5.

The weight ratio of water content after 24 hours of natural drying
15% to 20% semi-dry incense sticks 8 are arranged and placed on the upper plate 4 of the corrugated board 7 parallel to the ventilation direction of the ventilation passage 6 of the corrugated plate 3 without any gaps, as shown in Fig. 1. Or, as shown in Fig. 5, the incense sticks 8 are placed in two tiers, upper and lower, and the cardboard plates 7 are stacked in about 60 tiers on a carrier 9 in the same direction as shown in Fig. 6. Arrange them in two rows (120 sheets).

Then, another corrugated board is stacked on top of the upper board 4 of the uppermost stage, and a weight 10 is placed to apply a load.

Next, a hood 12 is attached to the outlet of the blower 11 to the device equipped with the above equipment, and the transport vehicle 9 with the semi-dry incense sticks 8 arranged and mounted on the hood opening 13 is placed so that the ventilation passage 6 of the corrugated board 7 is opened. Six units equipped with the above equipment were inserted into a sealed drying room 17 (floor area 50 m ² ) equipped with a dehumidifier 15 for dehumidifying and drying, and a hot air heater 16, with the densely ventilated surface facing forward. to warm the indoor air using the hot air heater 1.
While maintaining the temperature at approximately 30°C to 35°C and humidity at around 50%, the blower 11 blows hot air into the ventilation passage 6 of the corrugated plate 3, and the semi-dry incense sticks 8 with a diameter of about 2 mm are heated for 24 hours. Semi-dry incense sticks 8 of approximately 4.5 mm are continuously supplied for 48 hours.

As a result, an incense stick with a residual moisture content of about 8 to 10% can be obtained.

Note that the corrugated board 7 may be made of any material as long as both the upper plate 4 and the lower plate 5 are hygroscopic, such as paper, nonwoven fabric, synthetic paper, etc.

Further, if the blower 11 has sufficient power to blow air, the above-mentioned transport vehicle 9 carrying the incense sticks 8 may be arranged in two or three rows in front and behind.

Furthermore, when drying incense sticks with a rectangular cross section, if they are arranged between the upper plate 4 and lower plate 5 of the corrugated board 7 without any gaps between adjacent incense sticks, the moisture content of the incense sticks will be absorbed by the upper plate 4 and the lower plate. The board 5 absorbs moisture and dries, but even in this case, a large number of cardboard boxes 7 on which incense sticks are placed are
Since the incense sticks are stacked and dried while being pressed, the incense sticks can be dried to a normal state.

Furthermore, when drying flat incense K such as a square, circular, or flower-shaped incense stick shown in FIG. If the upper plate 4 and the lower plate 5 are arranged in such a way that they are arranged, each gap 14 formed between the upper plate 4 and the lower plate 5 will be communicated back and forth, and air will be blown. The incense K is dried by the action, and the incense K can be dried into normal flat shapes by drying from the surroundings of the incense K.

(Effects of the Invention) According to the present invention, the semi-dry incense stick 8 is sandwiched between the corrugated cardboard plates 7 and 7 having the ventilation passage 6, and the upper and lower surfaces of the semi-dry incense stick 8 are connected to the hygroscopic top of the corrugated cardboard plate 7. The board 4 and the lower board 5 absorb moisture on average, and the absorbed moisture is dehumidified by supplying hot air with the blower 11 to the ventilation passage 6 of the corrugated board 3 of the corrugated board 7, and at the same time, they are arranged in parallel without any gaps. A gap hole 1 formed between the adjacent incense sticks 8 and 8 and the upper plate 4 and lower plate 5
4 and 14 are also supplied with warm air and dehumidified,
The moisture in the incense stick is uniformly dehumidified and dried from around the surface, making it possible to dry the incense stick into a straight incense stick without warping.

In addition, by dehumidifying means and heating means, the temperature can be reduced to about 30℃
After being transported and installed in a drying room maintained at 35°C and humidity around 50%, the air blower 11 was used to forcibly supply indoor air from the opening surface of the ventilation passageway to the ventilation passageway. It can be dried without causing the harmful effects of flying.

In particular, a large number of cardboard boards 7 are stacked, and another cardboard board is stacked on the top layer, and the incense sticks 8 are always stacked.
Since hot air is supplied while pressing the incense stick under a load with a weight 10, etc., the area around the incense stick is evenly dehumidified, and it is possible to prevent vertical warping and horizontal distortion due to drying, so that the incense stick 8 is normal. The incense sticks are dried in a straight shape, and the extremely troublesome and time-consuming process of folding and removing the plates during drying in conventional natural drying can be completely omitted, and the work of drying incense sticks can be significantly improved.

In addition, the existing wooden incense stick drying board A can be used semi-permanently, but when incense sticks with different scents are dried on the same drying board, the smell will transfer to the drying board.
When drying incense sticks with different scents, it is necessary to wash and dry the incense stick drying board A, which is very time consuming, but according to the present invention, the cardboard board 7 used is inexpensive and costs about 40 yen. It can withstand repeated use for drying up to 50 times, and the cardboard board 7 is cheap and disposable, so only the same cardboard board 7 can be used for incense sticks with the same scent, and different Another corrugated board 7 can be used for items with odors to prevent the odor from being transferred, and the corrugated board 7 can be used efficiently.

Furthermore, the semi-dry incense sticks 8 are sandwiched between the cardboard plates 7 and stacked in multiple stages to form the upper plate 4 and lower plate 5 of the cardboard plates 7.
In the case of the present invention, hot air is forcefully blown by a blower 11 into the numerous ventilation passages 6 between the dryers, and in the conventional natural drying or forced drying method, drying plates are stacked at regular intervals. Compared to incense sticks that are dried, in the case of the present invention, the volume of the drying chamber is sufficient to be about 1/5 to 1/10 for the same amount of incense sticks, so the volume of the drying chamber can be significantly reduced. be.
