Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a drying aid for a hanger-type drying device for hanging leaf tobacco. More specifically, the present invention relates to a drying aid installed inside a drying chamber of a leaf tobacco drying device in order to improve the drying state of leaf tobacco suspended on a hanger.

(Prior Art) Conventionally, in the leaf tobacco drying apparatus as described above, for example, leaf tobacco is hung on hangers in a drying chamber in multiple stages, and hot air is circulated from the bottom to the top of the drying chamber to dry the leaf tobacco. It is known that it is made to dry. In order to save labor in attaching leaf tobacco to the hanger, the hanger is made into a round bar and the leaf tobacco is knitted onto the hanger using a sewing machine or the like and then attached to the hanger.

(Problem to be solved by the invention) However, although this kind of drying device that hangs leaf tobacco on hangers is easy to operate, it also causes the leaf tobacco that is hung in multiple stages in the drying chamber to be lined up and down. Because they are arranged in parallel, the spaces between the laterally adjacent leaf tobaccos connect vertically, forming a passage-like space that passes straight from the bottom to the top of the drying chamber.
As a result, since the passage-like air has less resistance than other parts, the hot air blows from the bottom to the top of the drying room through the passage-like air without going around to every corner of the leaf tobacco. There is a problem that the drying efficiency of the leaf tobacco is reduced and the drying result is poor, such as uneven drying and raw dryness.

The present invention was devised in view of these problems of the prior art, and its purpose is to improve the drying efficiency and drying finish of leaf tobacco in a hanger type drying device. .

(Means for Solving the Problems) The technical means achieved by the present invention to achieve the above object is to hang tobacco leaves knitted onto rod-shaped hangers using a sewing machine leaf knitting machine or the like in a multi-stage manner in a drying room. It is used in a leaf tobacco drying device that dries leaf tobacco by circulating and flowing hot air upwards through the lower skeins of the drying chamber, and has a thickness approximately equal to the distance between the adjacent hangers and approximately the same length as the hanger. It consists of a plurality of sponge-like interlocking materials of a length, and a string-like connecting material that connects the intervening materials so that a predetermined interval can be interposed between each of the intervening materials, and the intervening materials are connected between each hanger. The connecting member is fitted onto each hanger and supported on each hanger.

(Function) By using the above-mentioned technical means, a string-like connecting material is supported on each hanger that hangs leaf tobacco and is attached between the side walls, and a sponge-like connecting material is attached to each hanger.
When inserted between the hangers, the suspended leaf tobacco comes into contact with the adjacent spongy interlayer, and the interlayer acts as a resistance to the hot air blowing through the passageway, directing the hot air to the drying chamber. The moisture from the leaf tobacco is absorbed by the material while it is in direct contact with the tobacco.

(Example) Hereinafter, an example of a drying aid for a leaf tobacco drying device according to the present invention will be described based on the drawings.

FIG. 1 shows the entire leaf tobacco drying device 1 in which the drying aid according to the present invention is used. This leaf tobacco drying device 1 includes a drying chamber 11 and a hot air supply mechanism 1.
It consists of 2.

The drying room 11 has a slatted floor 11B with a large number of air supply ports 11A arranged on the entire surface, a side wall 11C, and a ceiling wall 11.
D, and an exhaust port 11E is opened at one location in the upper part of the side wall 11C. L-shaped crosspieces 11F with hanging holes 11G provided at regular intervals are fixed to a side wall 11C inside the drying chamber 11 in multiple stages (two stages in the drawing).
The end of the hanger 2 is removably locked in the hanging hole 11G of F in order to suspend the leaf tobacco 3 that has been knitted onto the rod-shaped hanger 2 using a sewing machine or the like into the drying chamber 11 in multiple stages. ing.

The hot air supply mechanism 12 is connected to the air supply port 11 of the drying chamber 11.
A, a furnace 12B that is connected to the exhaust port 11E and equipped with a burner 12A, and a blower 12
C, equipped with a heat exchanger 12D. Blower 12C
The air sent out is heated in the furnace 12B and becomes hot air W.
The air is arranged so as to be supplied to the air supply port 11A, and the exhaust port 11E and the outside air introduction port 12E are connected and communicated with the blower 12C. Note that the blower 12C and the exhaust port 11E,
The heat exchanger 12D is provided between the outside air inlet 12E and the outside air inlet 12E.
is arranged in connection with the exhaust duct 12F,
The hot air W discharged from the exhaust port 11E is transferred to the heat exchanger 1.
2D recovers heat and exhausts part of it from the exhaust duct 12F, and also transfers the recovered heat to the outside air inlet 1.
It is designed to supply air introduced from 2E.

Therefore, in this leaf tobacco drying apparatus 1, the hot air W circulates and flows from the bottom to the top of the drying chamber 11 to dry the leaf tobacco 3.

The drying aid of the tobacco leaf drying apparatus according to the present invention is used in such a leaf tobacco drying apparatus 1, and is composed of a spacer 4 and a connecting member 5.

The interlayer material 4 is made of a breathable and elastic material such as a sponge material, and is hung in a drying chamber 11 in multiple stages to knit leaf tobacco onto a rod-shaped hanger 2 using a sewing machine or the like. A plurality of long pieces are provided, each having a thickness equal to or greater than that between the adjacent hangers 2 and having a length equal to or greater than the length of the hanger 2 so as to be fitted between the two adjacent hangers 2. Therefore, the spacer material 4 is
It is compressed and fitted between each hanger 2 and between the side walls 11C and 11C (FIG. 3). As for the elongated shape of the material 4, it is shown in the drawing as a rectangular parallelepiped, as is clear from FIG. 2, but it is not limited thereto, and may be, for example, in the shape of a triangular prism. During this time, if the number of fillers 4 is one more than the number of hangers 2, they can be fitted between all the leaf tobaccos 3.

The connecting member 5 is made of, for example, a string-like material such as a rope, and is stretched between the shorter side surfaces of the connecting members 4 so that a predetermined interval can be provided between adjacent connecting members 4.
Regarding this connecting member 5, as is clear from FIG. 4, in the drawing, the central part of the connecting member 4 is penetrated in the widthwise direction to provide an exposed portion of a constant width between adjacent connecting members 4. However, the present invention is not limited to this, and it is also possible to connect to the shorter side of the spacer 4 via an attachment member, for example. It should be noted that if the structure of the connecting member 5 as shown in FIG.
If a stopper 6 is attached to the end of the exposed portion of the connecting member 5 from the connecting member 4, the connecting member 5 can be prevented from shifting.

When not in use, the drying aid consisting of the intervening material 4 and the connecting material 5 is stacked in a corner of the drying chamber 11 or at an appropriate location outside the drying chamber 11, as shown in FIG. Sometimes, by pulling the connecting member 5 from the laminated state, a connecting member 4 is inserted between each leaf tobacco 3 as shown in FIGS. 2 and 3. Therefore, installation and removal of equipment into the drying chamber 11 is extremely simple. During this time, when inserting the material 4,
Since it has elasticity, it will not damage the leaf tobacco 3. When the gap material 4 is fitted, the gap material 4
Due to the elasticity of the connecting member 5 and the hooking of the connecting member 5 to the hanger 2, the separating member 4 is prevented from falling off.

As shown in FIGS. 2 and 3, a drying aid consisting of a gap material 4 and a connecting material 5 is installed, and as shown in FIG. When the hot air W is supplied to the leaf tobacco 3, the blow-through of the hot air W is prevented by the barrier material 4, and the hot air W flows around to every corner of the leaf tobacco 3. Therefore, the drying efficiency of the leaf tobacco 3 is improved, and uneven drying and half-drying of the leaf tobacco 3 are prevented, resulting in a good drying finish. Note that since the spacer 4 has air permeability, the circulation of the hot air W is not completely blocked, and the circulation of the hot air W is ensured.

As mentioned above, in the illustrated embodiment, the drying aid according to the present invention is installed at each tier of leaf tobacco 3, but if it is installed at least on the top tier of leaf tobacco 3, the above-mentioned functions and effects can be sufficiently achieved. .

(Effects of the invention) Since the present invention has the above-mentioned configuration, the hanger-hanging type, in which the work of hanging braided leaf tobacco on a hanger and drying it, is easy, the present invention has the space between the leaf tobaccos that was conventionally available. This product is a hanger type dryer that can be closed and allows hot air to reach every corner of the leaf tobacco, resulting in good leaf tobacco drying efficiency and drying finish, which is very useful. Value can be improved.

In addition, since it has a simple structure consisting of a sponge-like interlayer and a string-like connecting material and is inexpensive, it can be easily hung on a hanger to increase drying efficiency, resulting in lower costs.

Furthermore, since the spongy interlayer is approximately the same thickness as the interlayer between adjacent hangers and approximately the same length as the length of the hanger, the leaf tobacco sandwiched between the adjacent interlayers will not dry out. Even if the leaf tobacco contracts, it expands as the leaf tobacco contracts, so the leaf tobacco and the interlayer are always in contact with each other, which maintains drying efficiency and prevents the leaf tobacco from falling off. Because it is in contact with
The moisture from leaf tobacco can be directly absorbed by the interlayer.
