Embodiments of the present invention will be described in detail below with reference to the drawings. In addition, in the description of the drawings, the same elements are given the same reference numerals and redundant description will be omitted.

FIG. 1 is a schematic diagram showing one embodiment of the excrement disposal material according to the present invention. The excrement disposal material 1 is an excrement disposal material used for disposal of human or animal excrement, and includes a plurality of granules 10. The particle size of each granular body 10 is, for example, 5 mm or more and 15 mm or less. Here, the particle size of the granular material 10 is defined as the diameter of the smallest sphere that can contain the granular material 10. The excrement disposal material 1 is used, for example, with a plurality of granules 10 placed in a box-shaped toilet.

The granular body 10 is configured to guide excrement into the granular body 10 . The granular material 10 has water absorbing properties. The granular material 10 contains Euglena powder. The weight proportion of the Euglena powder in the granular material 10 is preferably 1% or more and 10% or less. Euglena powder is a powder obtained by drying Euglena such as Euglena.

The granular material 10 is mainly made of an organic substance other than Euglena powder. Here, the main material of the granular material 10 refers to the material that accounts for the largest weight percentage in the granular material 10 among the materials constituting the granular material 10 . As the organic substance that is the main material of the granular material 10, for example, paper, used tea leaves, plastics, or okara can be used. It is preferable that the granular material 10 consists only of organic matter (including Euglena powder).

Paper refers to materials mainly made of pulp. Examples of papers include, in addition to ordinary paper, classified PVC wallpaper (paper obtained by classifying PVC wallpaper), fluff pulp, papermaking sludge, pulp sludge, and the like. As the plastics, for example, classified paper diapers (plastics obtained by classifying paper diapers) may be used. Preferably, the okara is dried okara.

FIG. 2 is a schematic diagram showing the granular material 10. As shown in FIG. The granular material 10 has a core portion 12 and a covering portion 14 . The core portion 12 has a granular shape. Examples of such granular shapes include spheres, cylinders, and ellipsoids. The core portion 12 has a function of absorbing and retaining water of excrement (especially urine). The core portion 12 is mainly made of an organic substance other than Euglena powder. The core portion 12 may or may not contain an adhesive material. As the adhesive material, for example, CMC (carboxymethylcellulose), PVA (polyvinyl alcohol), dextrin, or a water-absorbing polymer can be used.

The covering portion 14 covers the core portion 12. The covering portion 14 may cover the entire surface of the core portion 12, or may cover only a portion of the surface of the core portion 12. The covering portion 14 has a function of adhering the granules 10 that have absorbed excrement to each other to form a mass (clump formation function) during use. The covering portion 14 contains an adhesive material. The covering portion 14 is also mainly made of an organic substance other than Euglena powder. In this embodiment, both the core portion 12 and the covering portion 14 contain Euglena powder.

Next, as an embodiment of the method for producing an excrement disposal material according to the present invention, an example of a method for producing the excrement disposal material 1 will be described. This manufacturing method includes a preparation step and a granule formation step.

The preparation step is a step of preparing Euglena powder. In this step, Euglena powder may be manufactured from Euglena, or ready-made Euglena powder may be procured.

The granule forming step is a step of forming granules 10. In this step, the granules 10 are formed to contain the Euglena powder prepared in the preparation step. At this time, it is preferable to form the granules 10 so that the weight proportion of the Euglena powder in the granules 10 is 1% or more and 10% or less.

The granule forming step includes a core forming step and a covering forming step. The core forming step is a step of forming the core 12. In this step, a plurality of core parts 12 are formed by granulating the core material (material constituting the core part 12) using a granulating device. As the granulator, for example, an extrusion granulator can be used. Prior to granulation, the core material is subjected to pretreatments such as crushing, kneading, and adding water as necessary. In this embodiment, the core material contains Euglena powder, and the core 12 containing Euglena powder is formed.

The covering portion forming step is a step of forming the covering portion 14. In this step, the coating portion 14 is formed by applying powdered coating material (the material constituting the coating portion 14) to the surface of each core portion 12 using a coating device or the like. The coating material can be applied, for example, by scattering or spraying. In this embodiment, the coating material also contains Euglena powder, and the coating portion 14 containing Euglena powder is formed. Thereafter, post-treatments such as sieving (grain sizing) and drying are performed as necessary. Through the above steps, the excrement treatment material 1 consisting of a plurality of granules 10 is obtained.

The effects of this embodiment will be explained. In this embodiment, granular bodies 10 containing Euglena powder are formed. Euglena powder exhibits a deodorizing effect on bad odors such as ammonia odor. This is because paramylon, a component of Euglena, has a porous structure and adsorbs malodorous substances. Therefore, in the manufactured excrement treatment material 1, even if a bad odor is generated from the excrement remaining inside the granular material 10, the bad odor can be alleviated. Therefore, the excrement treatment material 1 and its manufacturing method that can alleviate the bad odor from excrement have been realized.

In order to fully bring out this deodorizing effect, it is preferable that the weight percentage of Euglena powder in the granules 10 is 1% or more. On the other hand, if the weight ratio is too large, the manufacturing cost of the granules 10 and, by extension, the excrement disposal material 1 will increase. From this point of view, it is preferable that the weight proportion of the Euglena powder in the granular material 10 is 10% or less.

The granular material 10 is mainly made of organic matter. Thereby, the granular material 10 suitable for incineration can be obtained. If the granular material 10 is suitable for incineration in this manner, the used excrement disposal material 1 can be disposed of as combustible waste, improving convenience for the user. When the granular material 10 is made of only organic matter, the granular material 10 particularly suitable for incineration can be obtained.

The core portion 12 has a function of absorbing and retaining water of excrement. In this case, most of the excrement introduced into the inside of the granular material 10 will remain in the core portion 12. Therefore, the excrement is likely to generate a bad odor, so the excrement treatment material 1 that can alleviate such a bad odor is particularly useful.

The granular material 10 has a two-layer structure consisting of a core part 12 and a covering part 14. Thereby, functions can be shared, such as having the core part 12 mainly take charge of the water absorption/water retention function, and the covering part 14 take charge of the lump forming function. By selecting materials suitable for the respective functions as the materials for the core portion 12 and the covering portion 14, multiple functions can be enhanced at the same time.

Both the core portion 12 and the covering portion 14 contain Euglena powder. Thereby, not only the bad odor from the excrement remaining in the core part 12 but also the bad odor from the excrement remaining in the covering part 14 can be effectively alleviated.

The present invention is not limited to the above embodiments, and various modifications are possible. In the embodiment described above, the case where the Euglena powder is contained in both the core portion 12 and the covering portion 14 is exemplified. However, Euglena powder may be contained only in either the core portion 12 or the covering portion 14. In that case, the amount of Euglena powder used can be saved, thereby reducing the manufacturing cost of the excrement treatment material 1.

When the Euglena powder is contained only in the core portion 12 of the core portion 12 and the covering portion 14, it is possible to reliably prevent the Euglena powder from scattering outside the granular body 10. On the other hand, when the Euglena powder is contained only in the covering part 14 of the core part 12 and the covering part 14, the deodorizing effect of the Euglena powder is not limited to the bad odor from the excrement remaining in the covering part 14, but also in the core part 12. This also applies to the foul odor from excrement left behind in the environment. That is, the deodorizing effect of the Euglena powder contained in the covering part 14 not only affects the bad odor generated in the covering part 14 but also affects the bad odor generated in the core part 12 and transferred to the covering part 14. Therefore, even a small amount of Euglena powder can efficiently alleviate the bad odor from excrement.

In the embodiment described above, the case where the granular material 10 has a multilayer structure consisting of the core portion 12 and the covering portion 14 has been exemplified. However, providing the covering portion 14 is not essential. That is, the granular material 10 may have a single-layer structure consisting only of the core portion 12. In that case, it is preferable that the core portion 12 contains an adhesive material.

In the above embodiment, the granular material 10 having water absorbing properties is exemplified. However, as the granules, water-permeable ones that allow excrement to pass through the inside of the granules may also be used. Such water-permeable granules also fall under the category of "granules that guide excrement into the interior," similar to water-absorbing granules. Even in water-permeable granules, some amount of excrement remains inside, so the present invention is useful because it can alleviate the bad odor from the excrement.
