Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for adding a liquid substance (including a suspension) such as a fragrance to a material in the form of leaves, strips, or powder using a nozzle.

Conventionally, tobacco materials have been processed by providing a plurality of cylinder-shaped main bodies lying diagonally and rotating them in tandem.
Tobacco materials were sequentially supplied to these materials and subjected to drying, cooling, and addition of liquid substances, but firstly, the degree of crushing of the materials was poor, and secondly, a large amount of liquid substances (particularly volatile flavorings) were lost. The disadvantages are that a lot of liquid material is wasted due to dispersion, the working environment is deteriorated, thirdly, a large installation area is required, and fourthly, manufacturing costs are high.

In contrast, in the present invention, the liquid substance addition device is configured in a vertical shape, the material is fed from the top, and during the falling process of the material, the material is repeatedly separated and collected by a hopper and a rotating dispersion disk inside the hopper. A vertical addition device that improves mixing precision and distributes the flow in the circumferential direction, achieving uniformity of the flow rate in the circumferential direction, making the addition uniform, and making it possible to reduce the degree of crushing of the material. We aim to provide the following.

Another object of the present invention is to configure the addition device in a vertical shape, supply the material from the top, and spray a liquid substance during the falling process of the material, thereby preventing the escape of fragrance, etc. It is an object of the present invention to provide a vertical addition device for efficiently adding materials to dispersed materials.

Another object of the present invention is that by having a vertical configuration, the required installation area is reduced, and when combined with the same vertical cooler, the entire device To provide a vertical addition device which enables a large reduction in the installation area, allows the direction of taking out the material after liquid substance addition treatment to be free in a plane, and imposes no restrictions on the layout.

Another object of the present invention is to provide a vertical addition device that can be manufactured at significantly reduced manufacturing costs compared to conventional devices that have a structure in which a cylindrical main body rotates. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings and an embodiment of a flavoring device for tobacco strips.

In the vertical addition device A, an inlet hopper 2, an intermediate hopper 3, and a delivery hopper 4, each having a circular horizontal cross section, are installed in the machine frame 1 from the top to the bottom, with their centers almost coincident and in a closed shape. It is installed in a connected state.

A lid plate 2a is provided on the top of the artificial hopper 2, and a dust removal duct 5 is connected thereto, and a material supply conveyor 6 is located in an opening 2b in the peripheral wall of the artificial hopper 2. A rotating shaft 7 is provided in the center, and a preliminary dispersion disk 8 is provided in the intermediate hopper 3 portion of the rotating shaft 7 directly below the narrow opening 2C of the inlet hopper 2. A distribution plate 9 is provided in the fourth portion directly below the narrow opening 3a of the intermediate hopper 3.

A plurality of fixed addition nozzles 10 are installed on the top of the dispersion plate 9.

11 is a fragrance supply pipe.

The preliminary distribution disk 8 and the distribution disk 9 are shaped like disks with a flat center and an upwardly inclined peripheral end 9a.

The lower part 4a of the delivery hopper 4 is formed into a duct shape, and two sets of photoelectric detectors 14 are provided in the vertical direction on the side wall of the lower part 4a of the delivery hopper 4.

A take-out conveyor 13 is provided adjacent to the lower part of the delivery hopper 4.

The speed of the take-out conveyor 13 is controlled by the photoelectric detector 14.

In the above configuration, the strip-like material sent by the supply conveyor 6 falls from the lower part of the inlet hopper 2 onto the preliminary dispersion plate 8 in the intermediate hopper 3, where the clumps are broken up and the material is disintegrated in the circumferential direction. The flavor is dispersed into the material and falls onto the dispersion plate 9 while making the flow rate uniform in the circumferential direction, and is dispersed outside the dispersion plate 9 and added to the moving material by the fixed addition nozzle 10.

The flavored strips of material are stacked on an unloading conveyor 13 at the bottom of the delivery hopper 4 and are detected by a photoelectric detector 14.
The speed of the take-out conveyor 13 is controlled so that the strip-shaped material always closes the lower part 4a of the delivery hopper 4, so that the fragrance is transferred while preventing it from escaping.

The dust removal duct 5 takes in air through the opening 2b, is spaced apart from the fixed addition nozzle 10, and descends.

Since it is blocked by the strip-like material, there is little escape of fragrance from the duct.

Figure 2 shows the vertical addition device A of the present invention and the vertical cooling device B.
This shows a case where the tobacco material is used in the tobacco industry in combination with a conveyor 15, and the tobacco material in the form of strips is fed into the cooler B by a conveyor 15, and is transported upward by a spiral vibrating conveyor 16 having a porous bottom. After being cooled by the air flow ejected from the bottom of the porous hole, the tobacco is transferred to the vertical adding device A through the connecting chute 17 and subjected to flavoring processing. It becomes possible to greatly reduce the installation area of a series of processing equipment for materials.

In addition, an experimental example of the flavor addition efficiency (the ratio of the amount of flavor added by the addition device to the strip-shaped tobacco material and the amount of flavor detected from the strip-shaped tobacco material after the flavor addition process) in this example. According to 62. when there are three fixed addition nozzles.
6%, compared to the conventional cylinder-shaped fragrance addition efficiency of 20%.
The effect is remarkable when compared to the fact that it was in the % range.

Furthermore, the particle size ratio of 1.5 mm or less (wiring net 1.5 □
According to an experimental example, the proportion of small-particle materials that are shaken out by the vertical flavoring device is 15.7%, and 16.8% in the case of the conventional cylindrical flavoring device. In comparison, the amount of material fragmentation due to flavoring treatment is reduced.

FIG. 3 is a vertical cross-sectional view of a delivery hopper according to another embodiment, in which the rotary shaft 7 has a hollow central portion 7a, and the central portion 7a is hollow.
A is used as a fragrance supply pipe, and an addition nozzle 12 is provided below the dispersion plate 9.

In comparison with the embodiment described in FIG.
Since 2 is rotary, it is possible to further improve the uniformity of fragrance addition.

Further, as for the shape of the preliminary dispersion disk 8, depending on the properties of the material, substantially the same effect can be obtained even if it is shaped like a hat in addition to the above-mentioned shape.

Since the present invention is constructed as described above, it is possible to reduce the crushing of fragile materials such as flaky materials.
In addition, it is possible to efficiently add liquid substances while reducing the amount of material added, and the installation area of the device can be reduced, and manufacturing costs can be significantly reduced compared to conventional methods. The extraction direction is free on a plane, and there are no restrictions on the layout.

In addition, there are a plurality of hoppers arranged in series in the vertical direction, a rotating preliminary dispersion plate located in the middle hopper so as to be located directly below the narrow opening of the upper hopper, and a rotating pre-dispersion plate located in the lower hopper. Since it is equipped with a rotating dispersing disk located directly below the narrow opening of the intermediate hopper, the tobacco material repeats separation and gathering, thereby increasing the mixing precision of the tobacco material and dispersing it in the circumferential direction. This makes it possible to achieve circumferential uniformity of the flow rate.

Furthermore, since the addition nozzle is located in the lower hopper at the periphery of the rotating dispersion plate, it is possible to efficiently and uniformly add additives such as flavorings to the tobacco material during the dispersion movement. .
