DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to recycled paper made from the residue of Chinese herbal medicine and a method for producing the same. The recycled paper according to the present invention provides paper and paperboard excellent in printability without printing trouble. is there.

[0002]

2. Description of the Related Art In general, Chinese herbal medicine is used in the same meaning as grass root bark (crude medicine) or decoction, and two or more kinds are mixed and used. This herbal medicine extracts a herbal extract from the roots and stems of herbs, and a herbal medicine manufacturer produces a large amount of herbaceous meal such as plant waste annually as industrial waste. Such industrial waste of herbaceous meal is not only unfavorable from the viewpoint of protecting the natural environment, but also has a large waste disposal cost. Therefore, it has been studied whether or not the herbal meal can be reused and effectively utilized, rather than simply discarded as industrial waste. As a result, it was examined whether or not recycled paper could be made from herbal meal.

[0003] By the way, conventional recycled paper uses, for example, waste paper raw materials such as newspaper waste paper and magazine waste paper in addition to raw pulp raw materials, squeezes and dries it using long nets and round nets, and further applies surface coating and the like. To produce paper and paperboard.

[0004]

However, when making recycled paper from herbaceous meal as a raw material, the herbaceous meal is too large in shape as a raw material for papermaking. Yes, the obtained paper also has disadvantages in printing workability, printing suitability and printing quality. In addition, the herbal meal emits a strong odor peculiar to Chinese medicine, but when this is mixed directly with paper raw materials, this odor is not very favorable in paper production and in use of the obtained paper products.

[0005] The present invention has been made in view of the above-mentioned points, and it is an object of the present invention to protect the natural environment by effectively utilizing herbaceous meal as a raw material for recycled paper without discarding it as industrial waste, and to reduce waste costs. It is intended to provide a recycled paper containing herbaceous meal and a method for producing the same, which saves the cost.

[0006]

The recycled paper containing the herbaceous meal according to the present invention is obtained by dispersing and mixing a finely ground and deodorized herbaceous meal in a paper raw material. Also, it is a recycled paper containing the pulverized herbaceous meal in a dry weight of 2 to 20% by weight per recycled paper product. Furthermore, a hydroxide of an alkali metal and / or an alkaline earth metal is employed as a deodorizing and fiberizing accelerator for herbal meal. Further, the method for producing recycled paper containing herbal meal according to the present invention, the hydroxide of an alkali metal and / or alkaline earth metal, and a herbal sludge meal in water after stirring and deodorizing and promoting fiberization treatment The herb sludge residue is finely pulverized and fiberized by a pulverizer or the like, and the ground material of the herb residue is dispersed in a paper raw material to make paper.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. Herbal remedies 2 containing 70-80% moisture in a package filled in container 1
Is transported by a transporting means such as a hoist 3 and the herbaceous meal 2
Is charged into the charging tank 4. Medicinal herb lees 2 is, for example, plant waste such as roots and stems that are discarded in the process of manufacturing Chinese herbs such as Bofutsushosan, Kakkonto, Hachimi-jiogan, etc., which are made by mixing multiple types of herbs according to various symptoms. is there. First, a predetermined amount of water is charged into the charging tank 4 by adjusting the valve 6 and the level meter 7 provided in the middle of the pipe 5 so that the charging concentration of the charging tank 4 becomes 5%. Then, an alkali metal and / or alkaline earth metal hydroxide and herbal meal are added.
The reason why the predetermined amount of the hydroxide of the alkali metal and / or the alkaline earth metal is put in the charging tank 4 is to promote the fiberization of the herbaceous meal and to reduce the unique strong odor of the Chinese medicine. In particular, among hydroxides of alkali metals and / or alkaline earth metals, caustic soda has a large amount of extracted and eluted herbal meal, has a large effect of promoting fiberization, and has a large effect of eliminating the odor peculiar to Chinese medicine. Further, it is inexpensive and is preferable in that it is a commonly used chemical in paper pulp.

A pipe 8 is provided outside the charging tank 4, a disintegrator 9 is provided in the middle of the pipe 8, beaten while circulating the herb sludge, and perform a pretreatment before being treated by a pulverizer 10 in the next step. . The herb sludge residue by 6-cut screen (not shown) was 80% or more immediately after defibration, but decreased to about 30% in 30 minutes after defibration.

The herb sludge in the charging tank 4 is disintegrated by a disintegrator 9.
The sludge that has been beaten and subjected to the pretreatment is introduced into the pulverizer 10 while the flow rate is adjusted via a pump 12 and a level meter 12 and a flow rate load controller 13 provided in the middle of a pipe 11 outside the charging tank 4. . As the crusher 10, for example, a free crusher or the like is used. This free crusher has, for example, a screen formed by ringing a perforated plate having a large number of holes having a diameter of 0.7 mm and a rotation speed of, for example, 5000 rpm. p. m
There are countless irregularities on the inside, and it is composed of the main parts such as a grinding wheel that performs high-speed impact grinding with the outer peripheral pin, and the sludge that has been pulverized in the grinding chamber to a predetermined particle size is discharged from the holes of the screen. The sludge that does not reach the predetermined particle size is repeatedly pulverized, and a pulverized product having a certain particle size distribution is obtained. The residue of herb sludge of the pulverized herbaceous meal pulverized by the pulverizer 10 was examined using the 6-cut screen (not shown).
It was about. By fiberizing and pulverizing to the size, paper and paperboard excellent in printing workability, printing suitability and printing quality without printing trouble can be obtained. In this example, the case where a crusher was used was described, but the present invention is not necessarily limited to this, and if an equivalent effect can be obtained, paper pulp production such as a beater or a disperser may be used. The ones used are also possible.

The pulverized material having a predetermined particle size distribution and pulverized by the pulverizer 10 is stored in a storage tank 14. The pulverized herbaceous meal is dispersed and mixed into the paper material of the next step via a pump 16 and a flow meter 17 provided on a pipe 15 outside the storage tank 14 and provided in the middle thereof. As shown in FIG. 2, when applied to the manufacturing process of coat white ball,
The first surface layer is made with a fourdrinier using a pulp raw material, the second layer is made with a round paper machine using a newspaper wastepaper raw material, and the third layer is made using a magazine wastepaper raw material. The back layer of the fourth layer is prepared by dispersing and blending a pulverized medicinal herb with raw materials of used newspaper, making a four-layered structure by a circular paper machine, and pressing and drying processes. After that, the surface layer was coated to obtain a coated white ball as recycled paper.

In the embodiment of the present invention, the case where the ground material of the herbaceous meal is dispersed and compounded on the back surface of the recycled paper has been described. However, the present invention is not limited to this.
In the case of lamination as in the embodiment, a pulverized herbaceous meal can be dispersed and blended in the intermediate layer. In addition, the present invention is not limited to reclaimed paper, but can be obtained by dispersing and blending pulverized medicinal herbs into one layer of paper and paperboard, and to provide recycled paper excellent in printing workability, printability and print quality. Obtainable. Another major reason for dispersing and blending the pulverized herbaceous meal in the back layer, as in the present embodiment, is to make it visually recognizable that the herbaceous meal is used. The reason why the blending amount of the pulverized herb lees was 2 to 20% by dry weight per recycled paper product is 2% by weight.
In the following cases, it is difficult to understand at a glance that herbal meal is incorporated. On the other hand, if the content is 20% by weight or more, the strength is low, and there is a problem in practicality when used in boxes and the like.

[0012]

As can be seen from the above description, the present invention is a recycled paper containing a herbal meal in which a ground material of deodorized herbal meal is dispersed and blended in a paper raw material. Can be effectively used as a raw material for recycled paper without discarding the herbaceous meal discharged in large quantities as industrial waste.
It is effective in protecting the natural environment and can save waste costs. In addition, by mixing pulverized herbaceous meal that has been pulverized and refined and deodorized, the pulverized material becomes fibrous and peels off. Thus, recycled paper excellent in printing suitability can be obtained.

Further, the recycled paper according to the present invention has less strong odor peculiar to Chinese medicine and can be used in the same manner as generally used paper and paperboard products without giving any discomfort.
