Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for separating the mesophyll and backbone of leaf tobacco.

As a known method similar to the present invention, US Pat.
8775 (4, 14, 1964), after cutting the tobacco leaves vertically and horizontally, the mesophyll that does not contain the backbone is separated, and only the remaining hollyhock meat attached to the backbone is deboned and separated into the mesophyll and backbone. There is a way.

At present, all leaf tobacco is stored in the form of curly leaves, but with this method, the leaf tobacco must be manually spread and fed one by one, making it difficult to process in large quantities and impractical.

The present invention solves the above-mentioned drawbacks, and provides a method for separating the leaf pulp and backbone of leaf tobacco, which is capable of mass processing regardless of the storage format of leaf tobacco, and which aims to improve the finishing ratio. The gist is as stated in the claims in the header.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

As shown in FIG. 1, the main components of the present invention include a step 1 of supplying leaf tobacco, a filling step 2, a leaf arranging step 3,
A boning process that includes a cutting process 4 and a separator 5 that are sequentially provided, a boning machine 6 that is connected to the bone removal section of the separator 5, and a separator 7 that is provided after the boning machine 6. 8, and multiple stages of deboning processes 11, 14, 17 having the same configuration as the deboning process 8, which are sequentially connected to the middle bone extraction part of the previous deboning process.
and the separator 5 and each deboning process 8, 11, 14, 1
A mesophyll extraction conveyor 18 connected to the mesophyll extraction part of the separators 7, 10, 13, and 16 in the final stage deboning process 17, and a core bone extraction conveyor connected to the core bone extraction part of the separator 16 in the final stage deboning process 17. It consists of 19.

The above-mentioned overflowing step 2 may be performed using a general rotary cylinder type conditioner, which applies heat and moisture to the leaf tobacco fed into the conditioner to maintain the temperature of the leaf tobacco at 55 to 60°C and the moisture content. It adjusts the humidity to 20-22% WB and is used to spread out shrunken leaves into a sheet. The leaf alignment process 3 is performed by wrapping the outlet end above the first conveyor 25 of the cutting process 4 between the humidity conditioning process 2 and the cutting process 4, and furthermore,
It is preferable to have a belt conveyor 20 provided with a transfer speed as high as 2 blood/mjn, and to align the leaf tobacco when transferring from the belt conveyor 20 to the first conveyor 25 in the cutting step 4. In addition, as another embodiment, as shown in FIG.
A mold groove 22 is provided, and the leaf tobacco is fed onto this groove and aligned in the direction of travel, or by a slight upward airflow 2 as shown in Fig. 4.
When leaf tobacco is naturally dropped into the chamber 24 with 6, the leaf tobacco may be aligned by utilizing the property that the leaf base is downward. In the cutting process 4, as shown in FIG. 5, a first belt conveyor 25 is provided downstream of the belt conveyor 20 so as to have the same conveyance direction, and the conveyance direction is perpendicular to the downstream side of the first belt conveyor 25. The second belt conveyor 27 provided in the same way as the first belt conveyor 2
The slit knives 28 and 29 are composed of round rotary blade type slit knives 28 and 29 provided on the 5 and second belt conveyors 27, Winnowa brushes 30 and 31, and a leaf presser belt 32, respectively. The leaf tobacco cutting speed on the first belt conveyor 25 is approximately 8 h/min.
The circumferential speed of the slit knives 28 and 29 is set to be the same as the cutting speed, or slightly earlier, and the slit knife 2
It is best to set the installation interval of 8 and 29 to about 40, considering that the leaf tobacco is slightly shrunken. 2nd belt conveyor 2
The leaf tobacco cutting speed in step 7 is about 4 h/min, and the circumferential speed of the slit knives 28 and 29 is the same as the above-mentioned cutting speed.
Or set it a little earlier, slit knife 28, 29
It is best to set the installation interval to 8.

The cutting process 4 can be carried out by using a method in which a plurality of slit knives 34 and 35 are provided at intervals of the cutting width as shown in FIG. Although a so-called cylinder-type cutting machine equipped with a plurality of 39s may be used, the apparatus shown in Fig. 5 performs reliable cutting, suppresses the generation of scraps, and enables large-scale processing. Good results are obtained. For the separator 5 and the deboning steps 8, 11, 14, 17, devices known in the tobacco industry can be used. The separator 4 performs a deboning process 8 to cut the leaf tobacco into four-sided shapes that do not include the backbone.
, 11, 14, 17 before passing through.

The purpose of the deboning process is to separate the mesophyll attached to the mid-bone into mesophyll and the mid-bone, and in addition to a combination of deboning machines and separators connected together, a deboning machine, A deboning device integrated with a separator may also be used. In the deboning process of the present invention, when conventional leaf tobacco is processed under the above-mentioned operating conditions using a device in which a combination of a known deboning machine and a separator are arranged in four stages in series, backbones are mixed into the separated mesophyll. The size of the hollyhock meat obtained when 1% and 3% of The bone method (compared to the full-build threshing method and the chip threshing method) has been confirmed to be advantageous in improving the finishing ratio by reducing the occurrence of small mesophylls.

In the method of the present invention, by arranging the humidity control step 2 and the leaf alignment step 3 before the leaf tobacco cutting step 4, the leaves can be spread out into a sheet shape even when the leaves are shrunken, such as the imaginary leaves. This allows for highly accurate and efficient cutting. In addition, because the tobacco leaves are cut into quadrilateral shapes in advance and the four-sided leaf tobacco is separated without the backbone, larger mesophylls can be obtained compared to conventional methods, and there is less crushing and waste generation. In addition, since the backbones are cut, there are fewer heavy and thick backbones mixed in with the mesophyll that does not contain backbones, which is obtained by separating, which improves the quality of the product. The properties of the backbones obtained at the same time are not extremely long and are uniform in length close to the cutting width, so that the subsequent backbone cutting process can be omitted.
