Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a treatment material for treating feces and urine excreted by pet animals such as dogs and cats housed in houses of general houses.

[0002]

2. Description of the Related Art As a fecal matter treating material for pet animals, for example, a material containing virgin pulp such as chemical pulp, mechanical pulp or semi-chemical pulp as a main component and adding an inorganic filler because the virgin pulp alone is lightweight, It is described in JP-B-3-8738. Further, a granular manure treatment material for pet animals, which is obtained by granulating and drying sludge such as papermaking sludge, has been proposed by the present inventor.
No. 77833.

[0003]

However, when virgin pulp is used in the above-mentioned conventional manure processing material,
Since the raw materials are expensive and the filler has to be added separately, not only is the price extremely high and the practicality is poor, but the precious natural resource of virgin pulp is wasted. Also, the manure processing material using conventional papermaking sludge can be manufactured at low cost,
Papermaking sludge has a wide variety of colors and components depending on the papermaking plant that discharges it, and since it is not possible to secure papermaking sludge with a stable composition, it is only possible to manufacture treated materials with unstable colors and compositions. Moreover, since the fiber length of the papermaking sludge is almost 1 mm or less, even if the fine fibers are granulated to form a granular aggregate, the surface becomes rough, and the product does not have a high-grade appearance. In particular, pet animals are bred in relatively wealthy households and are mainly petted, so it may be judged that products without a sense of luxury are worthless. Therefore, there is a demand for a manure treatment material for pet animals which does not use expensive virgin pulp and has a high commercial value.

DISCLOSURE OF THE INVENTION The present invention has been proposed in view of the above-mentioned conventional drawbacks and in order to meet the demands of the prior art, that is, on the surface of a granular aggregate of fine fibers,
On the surface of a manure processing material for pet animals on which a thin film containing starch is formed, and on the surface of a granular aggregate formed by agitating the raw material and agitating the fine fibers to a desired particle size, starch The present invention relates to a method for producing a manure processing material for pet animals, which comprises depositing a powder containing quality to form a thin film and drying the thin film.

[0005]

When a thin film containing starch is formed on the outer peripheral surface of the granular aggregate composed of fine fibers, the thin film is dried to be smooth and to have gloss and luster.
It will look very nice. Further, for example, in the state where the granular treatment material of the present invention is stored in a shallow container having an open upper surface, when a pet animal stools or urine, its moisture is absorbed from the thin film to the inside of the granular aggregate, and the thin film softens Since it melts or melts and has stickiness due to the starch quality, a plurality of adjacent granular aggregates stick to each other and harden, so it can be easily incinerated as it is, or easily as household garbage or as a combustible material. Can be processed.

[0006]

Embodiments of the present invention will be described in detail below. The animal excrement treating material of the present invention has, for example, 1.
Use of organic sludge (paper sludge, other sludge) and coffee bean scraps with a fiber length of 0 mm or less is economically effective as waste treatment, but waste paper or recycled paper pulp is used, Virgin pulp can also be used when manufacturing a high-quality manure processing material.

The fine fibrous raw material described above (having a water content of 6
0 to 80%), if necessary, a deodorizing agent such as fine powder obtained by crushing coffee bean scraps for the purpose of deodorizing, powder of tea leaves, etc., in an amount of 0.1 to 3% by weight based on the raw material of the fiber % And crushed sufficiently with a disaggregation device to obtain fine fibrous materials (0.01-
(About 1.0 mm) and further thoroughly stirred to adjust the water content to about 50 to 70%.

When the fibrous raw material obtained as described above is supplied to a granulator and granulated, a granular aggregate of fine fibers is formed. For example, the granules are passed through a sieve having a diameter of about 2 mm. Is sieved into particles of 2 mm or more, and the powder is attached to the surface while rotating the sieved particles.

The above-mentioned powder is starch (CMC, etc.)
Of 70 to 90% by weight, fine powder of water-absorbing polymer of 1 to 15% by weight, and deodorant consisting of concentrated liquid of tea of the Camelliaceae family of 1 to 3% by weight, for example, organic sulfur nitrogen compound An antibacterial agent composed of a composite agent of imidazole compounds is contained in an amount of 1 to 10% by weight, and the powder of each of the above components is sprinkled on the surface of the granules to be coated thereon.
In this case, the coating amount of the powder is 5 to 20% by weight with respect to the granular aggregate of fine fibers as the raw material. The powder is not limited to the above-mentioned four components, and may be composed of starch, a water-absorbing polymer and an antibacterial agent because a deodorant is added to the raw material in advance, or the starch and the water-absorbing high It may consist of molecules. Further, if virgin pulp fiber is used as a raw material, no odor is generated, so that it may be unnecessary to add a deodorant at all.

When the surface of the granule is coated with the fine powder as described above, the fine powder on the surface becomes wet due to the moisture contained inside the granule, and the water-absorbing polymer fine particles dispersed appropriately. As the powder absorbs water, the starch powder softens and the powder particles on the surface of the granules adhere to each other, so that the powder changes from fine powder to thin film. In this state, if a drying process is performed until the total water content becomes about 15% or less, the thin film is hardened, the surface becomes smooth, and the granular material becomes glossy. However, the inside of the thin film is an aggregate of dried fine fibers.

Therefore, the manure-treating material of the present invention comprises organic sludge typified by papermaking sludge, waste paper and recycled pulp,
Using fine fibers of about 1.0 mm or less made of virgin pulp or coffee beans scraps as a raw material, and coating the surface of a granular aggregate of this raw material with a fine powder containing a starchy substance or a water-absorbing polymer. To form a thin film.

Further, in the method for producing a manure processing material of the present invention, the surface of the granular aggregate of fine fibers is sprinkled with a fine powder containing starch and coated, and the fine powder is aggregated into a granular form. It is characterized in that a thin film is formed by water inside the body.

In the present invention, the deodorant is mainly used for the materials which generate odor, and the antibacterial agent is for preventing various bacteria from being generated or attached to the product. The starch powder is a component for forming a thin film on the surface of the aggregate, and the water-absorbing polymer powder is for keeping the thin film in a wet state at all times. The amount of the powder adhered to the granular aggregate of the raw material is 5 to 20% by weight is 5% by weight.
In the following, the thin film becomes thin and may be easily damaged, and the thin film has no effect. On the other hand, if it is 20% by weight or more, the thin film becomes thick, and it is wasteful, which is contrary to the purpose of the present invention of manufacturing at low cost.

According to the present invention, since the main component of the thin film formed on the surface of the granular aggregate is starch, the manure-treating material produced by drying has a very smooth and glossy surface, and has a good appearance and commercial value. Will be high. Also, when the manure processing material is stored in a shallow container and subjected to the treatment of feces and urine of pet animals, the water content of the manure will contact the thin film on the surface of each manure processing material to soften or dissolve it. Due to the starch quality, a plurality of adjacent excrement processing materials will adhere to each other. When a plurality of adhered manure treatment materials dries over time, the starch substance solidifies and hardens, so it can be incinerated as it is or treated as general household garbage, but it is flushed to the flush toilet. You can also

[0015]

Therefore, according to the present invention, only by forming a thin film containing starch on the surface of the granular aggregate of fine fibers, the thin film on the surface can be extremely reduced even though the inside is fine fibers. Since it is smooth and has gloss and luster, and is relatively hard and heavy, the pet animal will not splash or overflow outside the container when used in the container. Moreover, since the solidified by the water content of the manure when the manure is treated, only the solidified part needs to be taken out and incinerated, or treated in the same manner as kitchen waste in a general household, which is extremely easy to handle.

Further, when an organic sludge typified by papermaking sludge is used as a fine fiber as a raw material, a thin film is formed on the surface. Therefore, regardless of the color of the multicolored papermaking sludge, a stable product is always produced by the thin film color. Not only can it be manufactured, but also because it does not show fine fibers on the surface, it has a good appearance and a high-class appearance, and if the raw material is papermaking sludge, it can be manufactured at low cost and can be supplied to consumers at low cost, We can provide high value.
