【0029】
発泡した可塑化溶融組成物の発泡倍率は、1.2〜20倍で、1.2倍以下であると充分な軽量化できず好ましくなく、20倍以上になると軽くなり、風などで飛散するので好ましくない。
【0030】
また、パン屑を含有した動物の排泄物処理材を製造するには、一般的な造粒や押出成形技術等に用いられている公知の装置によって行なえばよい。これらの装置としては、単軸押出機、2軸押出機、パン型造粒機等を用いることができる。

BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below. Examples of bread crumbs include nonstandard products that do not become commodities, products collected from bread shops due to expiration dates, crust generated in the sandwich manufacturing process, dough generated in the bread manufacturing process, and the like.
[0016]
For example, in the case of a crust containing 25 to 40% by weight of water and preserving pregelatinized starch, it is not necessary to add water, and the desired shape can be easily obtained by molding using a screw type extruder or the like. Excretion treatment material is obtained.
[0017]
The starchy material is blended to provide excrement absorption, binder action, mutual adhesion with excrement absorbers, and nodule action.
[0018]
Examples of the starchy material include starch, modified starch, cellulose, high-molecular-weight polysaccharides, food residues, and the like, and can be used alone or in combination of two or more.

Examples of the food residue include potato skin, unrefined starch, and the like generated in the process of manufacturing tofu and snack confections generated in the process of manufacturing tofu.
[0020]
The addition rate is 10 to 200% by weight with respect to the bread crumbs. If it is less than 10% by weight, there is no auxiliary effect, and if it is more than 200% by weight, the cost reduction effect cannot be sufficiently obtained, which is not preferable.
[0021]
The urine-absorbing retention agent as a treatment material is blended to provide a backflow-preventing effect of the excrement absorbed in bread crumbs and the like, and to impart high absorption and retention of the excrement. The urine-absorbing agent is not particularly limited as long as it is a water-absorbing polymer.

The mixture can be heated and mixed, kneaded, plasticized and melted, and the plasticized molten composition obtained by extrusion can be molded into a predetermined shape.
[0028]
Depending on the desired application, for example, as a method for producing an excrement disposal material for the purpose of reducing the weight, a foamed lightweight excrement disposal material can be obtained by using a foam molding technique. The foam production method comprises mixing a starchy material containing bread crumbs as an essential component, a urine absorption / retention agent, an antibacterial / antifungal agent, a deodorant / deodorant and other additives, and extruding the composition with a screw type extruder. The mixture is heated, mixed and kneaded at 110 to 160 ° C., plasticized and melted, and discharged under normal pressure from a pressurized state, whereby the foamed plasticized molten composition can be molded into a predetermined shape.
[0029]
The expansion ratio of the foamed plasticized molten composition is 1.2 to 20 times, and if it is 1.2 times or less, it is not preferable because it cannot be sufficiently reduced in weight, and if it is 20 times or more, it becomes light and scatters by wind and the like. It is not preferred.
[0030]
In addition, in order to produce an animal excrement disposal material containing bread crumbs, a known device used for general granulation, extrusion molding technology and the like may be used. As these devices, a single-screw extruder, a twin-screw extruder, a pan-type granulator, or the like can be used.

65 kg of bread crumbs (50-80 mesh) obtained by crushing the bread ears from the sandwich manufacturing process was dried with oak (moisture content 77% by weight) generated from the tofu manufacturing process by a 110 ° C. blast drier. The water content of the obtained excrement disposal material pellets was 20.5% by weight as a result of molding under the same conditions as in Example 1 except that the water content was changed to 65 kg. As a result of drying the pellets with a dryer, 12.7% by weight of the excrement disposal material was obtained.
[0036]
[Comparative Example 2]
The excretion obtained as a result of molding and processing under the same conditions as in Example 1 without blending the starch / acrylic acid graft polymer (Sun Fresh ST-100) used in Example 1 and the ceramic antibacterial agent (Celaglaze) The moisture content of the material-treated material pellets was 17.6% by weight, and the excrement-treated material pellets were dried by a dryer to obtain 11.9% by weight of the material.
[0037]
The excrement disposal materials obtained in Examples 1, 2, and 3 and Comparative Examples 1 and 2 were evaluated by the following methods.
1) Water absorption: 10 g of a sample was placed in a 500 ml beaker, 1% saline was poured little by little, and the saline was absorbed at the time when the saline could not be completely absorbed (unit: ml).
2) Deodorization: 30 g of a sample was placed in a 300 ml Erlenmeyer flask, 0.2 g of 10% aqueous ammonia was placed in the sample, and the sample was sealed. After 10 minutes, the ammonia residual concentration in the flask was measured using an ammonia gas detector tube (unit: ppm).
3) Antibacterial and antifungal properties: 100 g of a sample was placed in a petri dish, and observed at a relative humidity of 60 to 90% in an open environment for 14 days, where the occurrence of mold and rot was observed, and the number of days of occurrence was evaluated. did. The odor at that time was evaluated.

The water absorption of Examples 1, 2 and 3 was about 4 times higher than that of Comparative Example 2 in which no urine absorbing agent was added. As for the deodorizing and deodorizing properties, ammonia odor was very small except for Comparative Example 2 in which a ceramic-based antibacterial agent having a deodorizing and deodorizing action was not blended. In the case of using okara as a main component in Comparative Example 2, the antibacterial agent having the same compounding amount as that of the system using bread crumbs rapidly caused mold and decay.
