DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to granulated materials for treating excrements discharged from pet animals including cats and dogs, and method for producing the same, and in particular to such granulated materials and method of producing the same for effectively utilizing residues generated after extract liquid has been extracted from roasted coffee beans.
BACKGROUND OF THE INVENTION
Small grains of sand, bentonire, zeolite, pulp for manufacturing papers, and pulp sludge have been conventionally used as an animal excrement treatment material in particular for use indoors.
Such an animal excrement treatment material is desired to be clean and hygienic because it is usually used indoors, and also desired to be easy to be disposed as waste so that cleanness and hygiene may be maintained. However, inorganic excrement treatment materials such as sand, bentonire, and zeolite is likely to be collapsed into powder when used, and further, even if they emit an offensive odor when long time passed after having been used, they cannot be burned because they are inorganic nor be allowed to dump away into a sewer system. For these reasons, small grains made from pulp for manufacturing papers and paper powder has been used because they have good water absorbency and can be burned in spite of their low deodorant property and higher cost.
With increasing demand for coffee drinks including canned coffee and instant coffee, residues which remain after extract liquid has been extracted from roasted coffee beans, which hereinafter are referred to as merely "the residues", have been generated a lot. In addition, since the residues contain a lot of fat, disposal of the residues costs high. Thus, the effective use of the residues solves the aforementioned problem which the coffee beverage industry has as one of its biggest problems.
However, there arises another problem in using the residues. Pet owners do not like the brown color which is the color of the residues. Since an animal excrement treatment material is usually used indoors, the material is required to have a color which can give sanitary feeling.
It is an object of the present invention to solve the problem that an animal excrement treatment material is decreased in value as a commodity because of the color which the residues have, namely brown.
DISCLOSURE OF THE INVENTION
It is an object of the present invention to provide an animal excrement treatment material which has superior absorbency and retention of urine discharged from animals and can make it possible to mass excrements by surrounding the material so as to facilitate burning of the excrements, and also can advantageously utilize the residues regardless of a color thereof.
In one aspect, an animal excrement treatment material in accordance with the invention mainly contains residues generated after extract liquid has been extracted from roasted coffee beans and is formed into dry grains having diameter not less than 1 millimeter. The material may be pigmented by coating at least a portion of surface thereof with pigmenting substances.
The invention provides a method of producing an animal excrement treatment material including steps of mixing predetermined substance with residues generated after extract liquid has been extracted from roasted coffee beans in less amount than the residues, forming the mixture into grains mainly containing the residues, and drying the grains so that they have water content not more than 10 weight %.
In a preferred embodiment, in the aforementioned mixing step, second substance having germicidal action may be added into the mixture.
In another preferred embodiment, in the aforementioned mixing step, pigmenting substance may be added into the mixture.
In another aspect, the invention provides a method of producing an animal excrement treatment material including steps of mixing predetermined substance with residues generated after extract liquid has been extracted from roasted coffee beans in less amount than the residues, forming the mixture into grains mainly
