Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a material for treating animal excrement, such as livestock and pet animals.

Conventionally, methods for disposing of excrement from animals, especially dogs and bed animals such as 3111, include a method using pebbles as litter, a method using waste paper, bulbs, etc. as granules and using them as litter, and a method using river sand. , and other methods using newspaper are known.

However, when using pebbles or river sand as toilet litter, although their hygroscopic and deodorizing properties are excellent to some extent,
There are problems such as having trouble finding a place to dispose of them, or pebbles or debris getting stuck in the toes of bedding animals, damaging the toes, or sticking to the toes and making a mess in the room. When molded and used as toilet sand,
These treated materials are convenient because they can be flushed into the toilet, but because they are lightweight, they can scatter on the bodies or limbs of bed animals, making the room dirty, and they also lack hygroscopicity. 0 As described above, the animal excrement disposal materials that have been developed or commercially available have both advantages and disadvantages, and there is a desire to develop even better excrement disposal materials. 0 Under these circumstances, The present inventors discovered that a mixture of vegetable raw materials with a high fiber content, starches, mineral raw materials, etc., when expanded and molded, becomes an extremely excellent animal excrement disposal material, and has developed the present invention. Manufacture of excrement treatment materials whose characteristic is that a mixture of complete starches or binders and mineral raw materials is added with water or humidity conditioned, kneaded under high temperature and high pressure, and extruded through the holes of a die. The purpose of this method is to provide highly absorbent water to animal excreta.
It has deodorizing properties, does not form a layer on the limbs or body of animals, and does not get caught in the toes of animals. Another object of the present invention is to provide a method for producing at low cost and in large quantities an excrement disposal material that can be used as soil improvement and fertilizer when sprinkled on gardens, fields, etc.

Among the plants of the M family with a high fiber content used in the present invention, 10% or more of fiber, preferably l! % or more (for example, various agricultural manufacturing by-products such as beet pulp, bagasse, gluten feed, starch meal, cytrus pulp, tomato pomace cake, pear cake cake, pineapple cake cake, etc.; oil cake such as safflower cake, sunflower cake, etc.) hay such as alfalfa, limber, rye grass, etc.; bran, bran; fir grains; waste paper, pulp 2 floc, sawdust, wood flour, and others. Select and use one or more suitable ones.

Cereals such as corn, wheat, barley, rye, oats, mulch, wood, millet, millet, millet, and their flours; #Powders such as corn starch, potato starch, wheat starch, tapioca starch; glucomannan, alginic acid, carrageenan, guar gum, CMC,
Examples include binding agents such as lignin and gum arabic, and one or more of these may be appropriately selected and used.

Furthermore, mineral raw materials used in the present invention include, for example, kaolin, sericite, gicrite, talc, seviolite, bentonite, acid clay, activated clay, silica sand, diatomaceous earth, pumice, Kanuma soil, zeolite, perlite. , vermiculite, calcium carbonate, oyster shell, seashell,
Examples include bone meal, and one or more suitable ones are selected and used from these.

Other raw materials include disinfectants, deodorizers, pH adjusters,
Examples include coloring agents, bleaching agents, flavors, etc., and these can be used as appropriate as required.

The production of 4J1 excrement disposal feathers according to the present invention is carried out as follows.

First, coarse plant materials and mineral materials with a high fibrous content are crushed and mixed with lees or a binder.

The mixing ratio of these raw materials is based on vegetable raw material IF with high fiber content.
i o~jO%, starch or binder! It is desirable to mix in the range of ~0% mineral raw material and 30-20% mineral raw material,
Especially plant materials with high fiber content 20-110%, starches or binders - 20-30%, mineral raw materials tO ~ 60%
It is preferable to mix within a range of %. A disinfectant, a deodorizing agent, an I)H regulator, a coloring agent, a bleaching agent, a flavor, etc. are mixed into these as appropriate. And the above-mentioned song I I4ΔI-h-L I it /l /

At that time, the moisture content to be adjusted varies depending on the composition and moisture content of the raw material mixture itself, but if the moisture content is low, the moldability will be poor (on the other hand, if the moisture content is too high, it will not swell, and the properly processed product will be Normally, the water content of the raw material mixture is i, g-<
It is desirable to add water or adjust the humidity so that it becomes .

Next, this raw material mixture is heated to a high temperature, for example, ioo~170C.

1 or more and extruded through the hole of the die. The raw material mixture extruded through the hole of the die becomes expanded. The swelling ratio lI:l: Any swelling ratio can be obtained by appropriately changing the urinary composition bottom, water content, temperature, pressure, diameter of the die hole, etc. It is desirable that the expansion is made so that the ratio (area/die hole cross-sectional area) is 1.2 or more.

Next, the extruded cutter surface of the die is cut to the desired size using a cutting knife located at the exit of the die. At this time, it is desirable that the length be approximately the same as the cross-sectional diameter.

For the above process, any machine or device can be used as long as it is capable of kneading the raw material mixture under high temperature and high pressure and extruding it through the holes of the die, but extrusion molding machines,
For example, an expansion pellet mill, an extruder, etc. can be used.

When extruded and expanded in this way, the moisture content decreases when it is extruded from the high pressure section to the low pressure or normal pressure section, but it is desirable to dry it further. It is possible to immediately dry the whole excrement to the treatment phase, but before drying, cut the cut surface of the swollen 11S into a round (
An even better product can be obtained by adding a rounding process.

Furthermore, even better products can be obtained by coating the cut material with a solution containing flavor, I)H regulator, beak color, polishing agent, etc. These rounding methods and coating methods can be arbitrarily selected and used.

The excrement disposal material obtained by the method of the present invention is particularly effective when used as an excrement disposal material for bed animals such as dogs, cats, rabbits, and hamsters, but it can also be used as an excrement disposal material for livestock such as pigs and cows. It can be used as a
It can also be used to dispose of excrement from sick and elderly people.

When the excrement disposal material obtained by the method of the present invention is used in a cat, for example, the length is about 100 m and the width is about 100 m (: M).

All you have to do is spread it in a container with a height of about 16 cm to a thickness of about J cm.

Since the excrement treatment material obtained by the method of the present invention is in the form of expanded granules, it has excellent absorption and deodorizing properties for excrement, and is suitable for plant materials, powders, minerals, and minerals. Because it is blended with water, it has a moderate specific gravity and will not stick to the bodies of animals such as dogs and cats, nor will it get caught in their fingers or toes, so animals will not pollute the room due to this. Nor. In addition, when disposing of these, it is not only possible to flush them down the flush toilet with M or 6, which has a moderate disintegration property in water (but also to improve the soil or use it as fertilizer in gardens, fields, etc.). It is extremely wide (and has an excellent effect).

Table 1 The absorbency of the excrement disposal material produced as described above was measured. The results are shown in Table 2. To measure the absorbency, water is absorbed little by little into 100 pieces of the excrement treatment material, and 7 minutes later, and! We looked at the absorption amount of the branches. In addition, as comparative examples, the absorbency of commercially available zeolite granules and valve floc granules was also measured. It is allowed to have sexual characteristics.

Example 2 After thoroughly mixing the raw materials having the composition shown in Table 3, the moisture content was adjusted with water and steam to a moisture content of 2 q%, and then the mixture was fed into a heating and pressure extruder and kneaded well under high temperature and high pressure. It was extruded through the pores of the die. At this time, the temperature was i<toC, and the pressure difference for extrusion from the die was 7, yB and C.

Table 3 Next, the water absorption capacity and disintegration in water of the excrement treatment materials obtained as described above were measured. To measure water absorption capacity, measure the sample into a beaker and let it absorb water little by little.
We looked at its maximum absorption amount. In addition, the disintegration property in water was measured by dropping a sample into a beaker filled with water and observing the shape after stirring for 30 minutes and 3F. The water absorption capacity and disintegration properties in water of the product and the zeolite granulated product were also measured in the same way.
The results are as shown in Table 4. From Table 4, it can be seen that the excrement treatment material of Example 2 has excellent water absorption ability and disintegration properties.

Table 4 In addition, the excrement disposal material A obtained in Example 2 was spread on a cat's toilet (3 x 3 cm / 0 cm) to a thickness of 3 cm,
We had a chat about its effectiveness as an excrement treatment material, and found that it has water absorption,
It was confirmed that the deodorizing property was also extremely excellent. Additionally, when this treated product was flushed down a flush toilet, it flushed away without causing any problems. When the group conducted the experiment on rabbits kept indoors, a significant effect was confirmed.
