Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material for treating excrement of small animals bred mainly by humans at home.

[0002]

2. Description of the Related Art The mainstream of conventional small animal excrement disposal materials is
The ore product is pelletized, and its particle size varies from large to small depending on the characteristics of the target small animal. Owners should choose small animal excrement disposal materials,
Materials and particles that match the characteristics of small animals are selected and put into an appropriate container, and only one layer is used, and the input amount is also used according to the weight and urine volume of the target animal. Is the current situation. In addition, the owner removes the small animal from the container containing the excrement disposal material, and then cleans and reuses the excretion disposal material, or disposes it as household waste at an appropriate time.

[0003]

In the conventional single-layered excrement disposal material, if the thickness is insufficient, urine moisture reaches the bottom of the container and diffuses along the bottom, so that a large amount of the disposal material is consumed. In addition, the removal of the processing material becomes extremely difficult. Also, even if the thickness is sufficient, the tip of the lump due to urine moisture does not reach the bottom of the container, but the thickness becomes thin, so that it is easily left in the container when taking out. There is.

[0004] In the case of a small animal requiring a treatment material, for example, a cat, in addition to objective differences such as the weight of the cat, the amount of urine, and the length of hair, the depth at which sand is dug by the cat, and urination. Each cat has a habit, such as a difference in posture, and the characteristics required for the processing material are different.

[0005] In addition, the requirements of the owner for the processing materials include the speed of urine absorption, the hardness after absorption, the ease of taking out lumps, the prevention of scattering of the processing materials out of the container, and the elimination of the smell of urine. In addition to odors, the demand for disposal after urine absorption is diversified, such as disposal as burning garbage, used as fertilizer, and flushed to flush toilets. Since the number of processing materials using the processing materials is increasing, breeders choose and purchase from various prepared processing materials.

However, these requirements have contradictory characteristics, and it is almost impossible to satisfy all the requirements with a conventional processing material having a single layer.

[0007]

SUMMARY OF THE INVENTION The present invention provides a two-layered excrement disposal material that can be arbitrarily combined, thereby urinating a small animal in need of the treatment material and excreting the animal. The object of the present invention is to enable the use of small animal excrement disposal materials that can satisfy any of the use environments required for the waste disposal materials.

[0008] More specifically, the first aspect comprises a pellet-shaped surface layer mainly composed of a plant and a powdery or granular base layer mainly composed of a plant.
It is used by laminating a surface layer on the upper layer.

According to the second aspect of the present invention, the surface layer is obtained by drying raw okara produced in the tofu production process, and corn starch is added to the dried okara and kneaded, and the corn starch is pregelatinized in the process of water supply and heating. Then, it is discharged and cut into pellets.

According to a third aspect of the present invention, the surface layer is obtained by adding water and a water-soluble adhesive component to dried okara obtained by drying raw okara generated in the tofu production process, and then pelletizing at room temperature. .

According to the fourth aspect, the base layer is a cereal powder, a wood powder, a bamboo powder, a leaf powder, a root vegetable powder, or the like obtained by pulverizing plant components.

According to a fifth aspect of the present invention, the base layer is formed by pulverizing a residue obtained by extracting fat, sugar, starch, protein, fruit juice, water-soluble fiber and the like from plant components.

According to the sixth aspect, the base layer is a powder obtained by crushing used and recovered products such as paper and printed matter, packaging materials, disposable diapers and the like, which are mainly made of vegetable pulp, and defective products generated during the production process.

According to claim 7, the base layer is a powder of incinerated ash, coal ash, charcoal, bamboo charcoal, or other activated carbon, which is a carbide of a plant component.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION The small animal excrement disposal material of the present invention comprises two layers: a surface layer for realizing the performance suited to the urination behavior of each small animal and a base layer for realizing the requirements of the owner. The surface layer is a pellet having an appropriate particle size to satisfy the feeling of use of small animals, and the base layer is a powder or a powder for strengthening the mass after urine absorption and facilitating removal.
It is in the form of small-diameter granules.

In the embodiment of the present invention, the surface layer is formed by adding cornstarch to dried okara obtained by drying raw okara generated in the tofu production process, kneading the mixture, and then supplying water, heating, discharging, cutting, and cutting. It is in the form of dried pellets, and the base layer is sawdust wood powder or bamboo powder generated in a wood cutting step or the like. In the surface layer, the added corn starch is heated and pregelatinized in the process of water supply, heating, discharging, cutting and drying, and has an adhesive function, so that it acts as a water-soluble adhesive when absorbing urine moisture. Since the base layer is in contact with the bottom of the urine absorbing portion of the surface layer, the base layer is bonded to the bottom by an adhesive effect of water absorption of the pregelatinized corn starch, and forms a firm mass with the surface layer. In the above-described processes from water supply, heating, discharge, and cutting after kneading, a kneading extruder having twin shafts may be used.

In another embodiment, the surface layer is prepared by adding a suitable amount of water and a water-soluble adhesive component to dried okara, then pelletizing with a granulator used at room temperature, and then drying. Wheat starch after gluten extraction or potato refuse after starch extraction is dried potato pulp or the like.
Although the surface layer contains only a minimal adhesive component, the adhesive component included in the base layer integrates the bottom of the urine absorbing portion of the surface layer with the base layer to form a firm mass.

As described above, according to the small animal excrement disposal material of the present invention, since the surface layer and the base layer are formed in two layers, the surface layer is formed into pellets having an appropriate particle size to remove urine. It is quickly guided to the lower part to prevent the collapse of the surface layer and the spread of urine to the side, and effectively acts to prevent the small animals from adhering to the hair and from scattering outside the container.

On the other hand, by making the base layer powdery or granular, when the base layer receives and absorbs urine that could not be absorbed by the surface layer, the urine is integrated with the bottom of the solidified surface layer and does not easily collapse. In addition, at the time of taking out, it is easy to peel off the unabsorbed portion, and the lump after absorbing urine can be taken out easily and reliably.

Incidentally, in order to cope with the difference in the amount of urine and the depth at which sand is dug by each small animal, the thickness of the surface layer may be changed.

In producing the surface layer according to the present invention,
The same process as that of the conventional product is required, but the amount of the water-soluble adhesive or the like to be added can be minimized because the necessity of mutual bonding during urine absorption is low. Further, since the base layer according to the present invention is in the form of powder or granules, pellet processing as in the prior art is unnecessary, and the used materials can be reused as waste.

In addition, in the case of emission-type deodorization of a malodor after excretion of a small animal, a scented substance may be added to the base layer. Any substance can be used as the fragrance substance, as long as it has a low moisture content and is in the form of powder or granules. Perfumes impregnated and dried can also be used. In addition, when performing adsorption-type deodorization, powdered activated carbon or the like is mixed into the base layer,
A lump of activated carbon or the like may be arranged below the base layer.

[0023]

The excrement disposal material for small animals is required to be as inexpensive as possible and simple in handling for the purpose of use, but cat excrement is particularly bad since it has a bad smell. Smell is also an essential issue.

In this respect, the present invention has a two-layer structure consisting of a surface layer and a base layer, so that inexpensive waste can be used as a material, processing can be performed with an inexpensive apparatus, and production at a low running cost is possible. Became possible.

In addition, a comfortable use environment can be obtained by adjusting the thickness of the surface layer to the characteristics of the urinating operation of the cat, and the lump of the urine absorbing portion is strengthened by the base layer. In addition, the handleability is improved, such as easy removal and little leftover occurs.

For deodorizing, the addition of a powdery or granular scent component or the like to the base layer facilitates the scenting, so that the owner can select and add a scented material of his choice. .

Also, due to consideration for the global environment, reduction of waste is an urgent issue. However, in this aspect, unlike the conventional ore products, which are the mainstream of manure processing materials, resources such as plant components The use of circulating materials as a raw material, and the effect of improving the disposal method such as burning, returning to soil, and flushing to flush toilets is also great.
