Because the excretion treating material comprises a starch of fine powder or granule, the excretion treating material has excellent absorbing properties and bulk formation and is readily abandoned.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an edible excrement disposal material for treating excrement excreted by animals.

[0002]

2. Description of the Prior Art Manure excreted by animals such as dogs and cats housed indoors has been conventionally processed by pulverizing minerals such as sand, clay, zeolite, and bentonite, and granular materials made from pulp. It absorbs excrement and processes it.

[0003]

It is known that small animals kept in general are easily affected by the surrounding environment and their eating habits sometimes become significantly different. In particular, when a person is strongly stressed by the influence of the outside world, a significant change in eating habits is observed, and the behavior of eating something different from normal foods is expressed. This abnormal eating behavior is especially called heterotrophic, and not only does it select edible substances that are different from the foods you normally eat, but also that you eat inedible substances such as sand and soil. As a result, it may lead to indigestion, impair health and lead to death. As an excrement disposal material for animals that may take such behavior, using sand, clay, zeolite, conventionally used inorganic materials such as bentonite and granular materials made from pulp or waste paper are used. It is not a preferable method from the viewpoint of animal health.

[0004] As examples of using other organic substances as materials, for example, mandarin orange shells, grass and the like have been proposed (Japanese Patent Publication No. 3-46089), but these substances may be used for feed. The animals that can be applied, if any, are limited to ruminants and the like, and when eaten by small animals in general, they have a negative effect on the digestive system.

In addition to the above problems, there is a problem of waste disposal of excrement disposal materials after use. Manure excreted indoors such as dogs and cats is preferably treated immediately, but sand,
Inorganic substances such as clay, zeolite, and bentonite cannot be washed away in flush toilets, so it is necessary to dispose of them in a suitable outdoor place.However, such places cannot be easily found in the city, so wait until the day of garbage collection. The reality is that they are disposed of together with kitchen waste. Also, in the case of sand, zeolite, etc., when the excrement contains a lot of water such as urine, it is necessary to replace all the treated materials because it spreads uniformly over the treated materials. However, at that time, there is also a problem that a dirty treatment material adheres to the legs of the animal and soils the inside of the animal. On the other hand, those made from pulp or waste paper have dissociability in water and therefore can be treated in a flush toilet, but have the drawback of poor water absorption and nodularity when excreted. .
For these reasons, excrement disposal materials that are safe for domestic animals and that can be easily disposed of are desired.

[0006]

The animal excrement disposal material of the present invention is characterized in that it is composed of a granulated product consisting of only edible starch or the granulated product as a core. is there. The raw material starch species used in the present invention are not particularly limited, and corn starch, wheat starch, potato starch, sweet potato starch, tapioca starch and heat, acid,
Examples thereof include edible starch obtained by modification with an enzyme, such as acetic acid esterified starch and pregelatinized starch.

As a method for granulating these starch raw materials, a suitable amount of water is added to the starch and kneaded to form a clay-like paste or paste, and then a conventionally known granulator, for example, It is possible to use a method using a compression roll, a pellet manufacturing disk, a fricking machine, a pellet mill, a rotary plate, a tableting machine, a mixing granulator, a screw type extruder, an injection type spherical maker, a sugar cube molding machine and the like. Upon granulation, an aqueous solution of gelatin, pregelatinized starch or the like may be used as a binder in an amount within the range that does not impair the absorbability of the granulated product. The granules of the excrement disposal material of the present invention may be spherical, tablet-shaped, pellet-shaped, prismatic, crushed, or any other shape. The size of the granulated product is not particularly limited, and may be a sandy to granular size depending on the animal to be raised. For example, in the case of dogs and cats that are housed indoors in ordinary households, the particle size is usually 5 mm.
The following is preferred, and it is usually used in the range of 2 to 3 mm, but 0.3 to 0. 0 for hamsters, guinea pigs, small birds, etc.
It may be used as sandy particles of about 8 mm.

The edible excrement treating material for animals, which has the granules of edible starch as the core used in the present invention, makes the granules into lumps due to the water content after excrement of manure, which makes them easy to discard. In order to absorb the urine or to absorb the urine rapidly and in large amounts, other edible substances, for example,
CMC (carboxymethyl cellulose), sodium alginate, protein and the like may be used in combination. Although the edible excrement disposal material for animals of the present invention does not impair health even when ingested by small animals, since it is composed mainly of tasteless and odorless starch, in the normal case, small animals prefer to eat. There is nothing to do. Since the starch is white, it may be colored to suit the taste of the animal. As a coloring method, the raw material itself may be colored with an edible dye or the like, or the surface of the granulated product may be colored or a colored product may be attached to the surface. In addition, colored foods such as charred wheat flour may be used for coloring.

[0009]

The present invention will be described in detail below with reference to examples, but the present invention is not limited to these examples. Example 1 To 100 parts by weight of corn starch was added 5 parts by weight of warm water at a temperature of 30 ° C., and the mixture was extruded through a wire mesh of 20 mesh, cut into granules having a length of about 1 mm, dried and agglomerated. Thus, the edible excrement disposal material for animals of the present invention was obtained. Example 2 100 parts by weight of the starch granules obtained in Example 1 were sprayed with 10 parts by weight of a 1% by weight aqueous solution of CMC (carboxymethylcellulose), the mixture was dried, and the animal-edible excretion of the animal according to the present invention was performed. A material treatment material was obtained.

Comparative Example 1 Bentonite was crushed and sieved to obtain a granular material having an average particle size of about 4 mm, which was used as an excrement treating material. Comparative Example 2 Chemical pulp was used as a raw material, and this was granulated and dried using an ordinary extruder to obtain a granular material having a particle diameter of about 4 mm, which was used as an excrement disposal material.

Test Example 1 In order to test the intake safety of the edible excrement disposal materials for animals obtained in Examples 1 and 2, 10 wt% was mixed with another cat food (dry food), Cats (2 years old, female, weight 3.0-3.2 kg, hybrid) were fed continuously for 1 month so that the edible excrement disposal material intake was 10 g / day. No change in appearance such as gloss of hair was observed. On the other hand, in Comparative Examples 1 and 2, normally only the excrement disposal material is left uneaten,
When they were forcibly fed, diarrhea and weight loss were observed in both cases.

Test Example 2 Next, using the excrement treating materials obtained in Examples and Comparative Examples, water absorption capacity, nodularity and ease of treatment were measured. The test method is to spread these excrement disposal materials in a plastic flat plate type container with a thickness of 5 cm,
100 mL of 0.9% saline solution was added dropwise to one point in the central part, and the water absorption and nodularized state of the portion where the saline solution was added were evaluated visually and by touch (touch).

The water absorption capacity was calculated by the following formula. W1 is the weight of the excrement disposal material W2 is the weight of the excrement disposal material after absorbing water

For the evaluation of the nodularity, ○ means that it feels firm when pressed lightly with a finger. △ is a little soft although it is solid. × means that the pieces fall apart. Expressed as The results are shown in Table 1.

For the evaluation of the processability, it was judged whether or not only the nodularized portion could be taken out and discarded. ◎ indicates that only the nodularized portion can be easily taken out and washed with water. ○ indicates that only the nodularized part can be taken out easily. △ is hard, but it is difficult to take out. × is broken apart and cannot be taken out. Expressed as The results are shown in Table 1.

EFFECTS OF THE INVENTION The present invention has the composition as described above, and since starch is a powder composed of fine particles, it has excellent water absorption and agglomeration even when it is wet with urine and the like. Since only the granulated material rapidly solidifies into a nodule,
Only that part can be removed with chopsticks. Further, since it easily disintegrates in water to become individual starch granules and can be discarded in the flush toilet, it is not necessary to keep excrement indoors for a long time. Furthermore, since the water absorbency is good, the treatment material under the feet of the animal does not get wet during urination, so that the treatment material wet with excrement is not stepped on by the animal, and therefore the inside of the room is dirty. Absent. From these facts, it is easy to handle as an animal excrement disposal material, and because it is edible, it is harmless to the animal's body even if the animal eats it. It has advantages.
