Abstract

<P>PROBLEM TO BE SOLVED: To solve problems on the leaving of excreta, such as the development of stinks and the attraction of curs and the like, due to the excreta, while conventional river sand, zeolite of mineral system, and paper or pulp-based, so-called cat sand, which are used as toilet articles, are thrown away as non- flammable refuses, or virtually illegally treated because of being incapable of being incinerated at homes. <P>SOLUTION: This method for producing the biodegradable excreta-adsorbing sand for the pets comprises adding biodegrading bacteria to a natural wood- based raw material. The biodegradable excreta-adsorbing sand can prevent stinks after the adsorption of pet excreta and can privately be treated by biodegradation after used, and the biodegrading function can be maintained by the adjustment of water content. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manure adsorbing sand for a toilet used for treating manure of pets such as dogs and cats and small animals, and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, so-called cat sand, which is made of natural river sand, mineral zeolite, paper pulp, and other raw materials, is mainly used for pets kept indoors. Due to its ease of use and deodorant effect, it is widely used as a toilet article mainly for cats. However, natural river sand is not used so much at present due to problems such as sampling and homogenization, and mineral zeolite etc. are excellent in product homogenization and deodorizing effect by industrial granulation processing. However, although it is widely used at present, there is a problem that in the treatment after the adsorption of the filth, the combustible waste cannot be treated because it is a mineral-based substance, but it is practically illegally discarded together with the combustible waste.

[0003]

Cat sand, which uses a paper-pulp-based raw material that is a flammable material, has begun to spread rapidly in recent years, but now that it is difficult to incinerate it at home, it is possible to burn combustible waste. Is being thrown away, which is against the reduction of garbage emissions. Also, regardless of the amount, if you put pet excrement as general household waste in a garbage bag and leave it in the garbage collection area near your house, not only will it generate a foul odor, but also call for stray dogs, stray cats, and crows. It can be.

[0004]

The present invention utilizes a natural wood raw material such as wood, and has the advantage of being a lightweight and flammable material such as paper-pulp-based material, which has become popular recently. Further, since the wood raw material is once crushed and granulated industrially, there is no problem in homogenizing the product.
The product is made by adding biodegradable bacteria to this so that it can be biodegraded in the same way as household garbage treatment and has a deodorizing effect.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION As the main wood raw material, not only general wood but also thinned wood and scraps and sawdust at the time of lumber are effectively used, but depending on the kind of wood used as raw material, For example, due to the insect-control and deodorant functions of the tree itself such as Hinoki thiol in Hinoki, it is possible to effectively use the functionality of natural ingredients.

[0006] After the wood raw material is put into a crusher, cut and crushed, and sifted and selected, the particle diameter of the raw material is finely homogenized, and a solidifying material, an adsorption promoting material and the like are mixed with this. It is 50% or more, and the product retains a woody texture.

Next, biodegradable bacteria are added to and mixed with the mixed and homogenized raw material, and water is further added to enter the kneading step. However, the raw material expands due to water to increase the bulk, and this is commercialized. It has the effect of increasing the water absorption rate.
Moreover, since the added bacteria will be killed unless attention is paid to the temperature control, the temperature rise is suppressed by gradually adding water.

[0008] Although all the raw materials have been mixed by the kneading process and the bulked and homogenized raw material has an appropriate moisture content, the activity of bacteria is minimized to improve the shelf life of the product. It is necessary to adjust the water content in order to suppress this.

Next, the raw material is granulated into pellets, but the shape may be any shape such as spherical, short rod or crushed. Usually, pellets formed by pressure extrusion are more efficient in forming and processing.

The pelletized material is then dried to a water content of about 10% by a drying process to suppress the activity of the added bacteria. A higher degree of dryness is desirable for the absorption of pet feces and urine, but a water content of this degree is required in order to maintain the living environment of bacteria and prevent the pellet state from collapsing due to overdrying. In addition, in the drying process, careful control of temperature and humidity must be carried out while paying attention to bacterial death.

Regarding the amount of bacteria to be added, when the product of the present invention alone has sufficient biodegradability, it can be treated together with household garbage in a general household garbage processor at ordinary households. When using a dedicated manure adsorption sand processing machine, or when using household compost, etc., it is possible to add a decomposition accelerator separately. The species should be adjusted to the minimum necessary to prevent overgrowth.

[0012]

The present invention is constructed as described above and has the following effects.

[0013] It is a product that can effectively use scraps and sawdust from sawmill that have been incinerated up to now, and that has a light-weight and excellent absorption rate that is not inferior to that of paper pulp-based cat sand. It also has the feature that it can be treated in-house as well as the garbage treatment.

By using a natural material called wood raw material as a main material and using a natural material for the additive mixture, not only pets excreted indoors but also manure treatment and cats even though they have insect repellent and deodorant functions. It is possible to provide products that are harmless to direct contact with the human body, such as sand replacement work.

Since it has an appropriate water content, the added bacteria can survive for a long period of time, and the individual pellets are easily aggregated, and have a soft feeling and become powdery with the effect of being less likely to scatter in the room. is there.

The adsorbed sand removed by excrement of feces from pets basically has sufficient biodegradability even with the product of the present invention, but if it is decomposed with a dedicated small-sized agitation biodegradation processor, Processing time is reduced. In addition, due to the composition of biodegradable bacteria mixed and mixed with natural woody raw materials, it can be thrown into general household garbage disposers widely used in households for treatment, or decomposed even if thrown into compost installed in the garden. It has a feature that it can be treated and that it can reduce the amount of dust by self-treatment after use and disposal and can prevent the generation of offensive odors when taking out dust.
