BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pet excrement disposal material for treating excrement of pets such as dogs and cats kept indoors and a method for producing the same.

[0002]

2. Description of the Related Art A large number of treatment materials for pet excrement are known, and those using papermaking sludge as a raw material are described in, for example, Japanese Patent No. 2516060. The pet excrement disposal material described in the above publication is mainly composed of papermaking sludge and calcium carbonate, granulated by utilizing the water content of the papermaking sludge, and dried.

Further, as a pet excrement treating material containing wood powder as a main component and adding water to a mixture of powdery bentonite, powdery super absorbent resin and powdery binder to add granules. Is disclosed in Japanese Patent No. 2947615.

[0004]

However, since the above-mentioned treatment material containing papermaking sludge as a main component is fibrous, it has strong caking ability and absorbs water and retains water, but its dispersibility in water is low. Therefore, if it is flushed into a Western-style flush toilet, problems such as clogging will occur. Further, the treatment material containing fine wood powder as a main component easily softens and disintegrates when it comes into contact with pet excrement such as water. For this reason, when used by a pet, a large amount of treatment material has to be taken out and discarded, so that a wasteful amount is used and the commercial value is reduced. Therefore,
INDUSTRIAL APPLICABILITY The present invention can be commercialized very easily and surely by molding by a dry method, and due to the synergistic action of wood flour and vegetable fine fibers, it is hard and has a high water retention property, and it has high commercial value. It is intended to provide a treatment material for use.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on embodiments. The raw material used for the pet excrement disposal material of the present invention basically relates to a pet excrement disposal material containing wood powder and vegetable fine fibers as main components.

As the wood powder used as a main raw material, sawdust generally produced at a factory for processing wood such as a sawmill or a woodworking factory is used. The wood powder has various shapes such as curled shape and powder shape, but any shape can be used in the present invention.

Further, as the vegetable fine fibers, papermaking sludge, coffee bean scraps and the like are economically effective as a waste treatment, but pulp such as waste paper or recycled paper can be used. In addition, virgin pulp can be used in the case of producing an excrement disposal material having a high quality and high commercial value.

In the present invention, the wood powder from which the inorganic substances and other foreign substances have been removed is thoroughly mixed with the vegetable fine fibers, and the mixture is supplied to a drying device until the water content becomes about 5 to 10%. The mixture which has been dried and sufficiently dried is supplied to a pulverizer to obtain a powder of 20 to 300 mesh.

In the above, the mixing ratio of wood powder and vegetable fine fibers is 40 to 85 parts by weight of wood powder and 15 to 50 parts by weight of vegetable fine fibers, and the wood powder has good disintegrating property. It is highly water-absorbing and water-retaining, and the vegetable fine fibers have good caking strength and water-absorbing and water-retaining properties. Therefore, when the amount of wood powder is 40 parts by weight or less, the amount of the vegetable fine fibers is too large to be hardened, and when the amount of the wood powder is 85 parts by weight or more, the vegetable fine fibers have a low caking force, which makes molding difficult. Further, when the amount of the vegetable fine fiber is 15 parts by weight or less, it is difficult to mold, and when it is 50 parts by weight or more, the amount of the wood powder blended is small, and a sufficient function of the wood powder cannot be expected.

The powdery mixture of the above-mentioned wood powder and vegetable fine fibers is, for example, sufficiently agitated and mixed without using a liquid by a dry mixing device utilizing a jet stream of air, and then from the dry mixing device, For example, a bag filter is used to collect only the powdery mixture.

The collected powdery mixture is supplied to a tableting machine which is a dry molding machine, and is pressed into a tablet material having a spherical shape, a circular shape, a polygonal flat plate shape, a lump shape or the like of about 3 to 10 mm by pressure. It is molded into a product.

Therefore, according to the present invention, the first step of sufficiently stirring and mixing the wood flour and the vegetable fine fibers at a constant mixing ratio, the second step of removing foreign matters from the mixture by the first step, and the above The water content of the mixture in the second step is 5 to 1
The third step of drying so as to reduce to about 0%, the fourth step of making the mixture finished the third step into a powder form of 20 to 300 mesh, and the powdery mixture in the fourth step by a dry method. It comprises a fifth step of stirring and mixing, and a sixth step of molding the mixture sufficiently stirred in the fifth step into a tablet material by a dry method, and all steps are a dry method using no liquid. It can be easily molded.

Further, since the wood powder does not come into contact with the liquid at the time of molding, the binding property of the plant fine fibers can be enhanced by the lignin contained, and the wood powder has a sterilizing function, a water absorbing function, a water retaining function and a contained component. It is possible to effectively function without deteriorating the deodorizing function, sterilizing function, aroma function and the like by hinokitiol.

According to the present invention, a water-absorbing high-molecular polymer is added to improve swelling property, and starch is attached to a part of human excrement when it comes into contact with excrement. Bentonite for the purpose of deodorizing, zeolite for the purpose of deodorizing, calcium carbonate for enhancing the deodorizing effect and exhibiting a white color and vegetable activated carbon for the purpose of deodorizing one or more kinds are added. be able to.

The above-mentioned additives are all 3 like the raw materials.
It is a powder form of 0 to 300 mesh, and when about 2 to 20 parts by weight is added, the function of each additive can be fully utilized. Then, the additive can be supplied together with the raw materials to the tableting machine of the sixth step, but the additive is added to the mixture after the fourth step of crushing the raw materials into powder, and in the next fifth step. The raw material and the additive material may be mixed and molded into a tablet material in the sixth step.

Therefore, when the powdery additive material is added, the excrement-treating material for pets produced has improved functions of the additive material to be added, as compared with the excrement-treating material not added. Value can be increased.

On the other hand, it has a low value as a pet excrement treatment material because it disintegrates easily, and a "bad" disintegrating property is unlikely to disintegrate even if it comes into contact with water, so it has a low value as a pet excrement treatment material, and a solidifying "Bad" is poorly maintained as a tablet material and is of low value as a pet excrement treatment material. "Too good" because it is hard to set is valuable as a pet excrement treatment material because it is hard and shape retention is too stable. Means low.
