BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drained powder and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, various treatment methods have been proposed for the treatment of animal blood drainage, and among them, adsorption drying, vacuum drying and the like have been considered for powdering animal blood drainage.

The applicant of the present application has already proposed an animal drainage powder obtained by reacting animal drainage with calcium oxide and a method for producing the same (Japanese Patent Application No. 4-270910).

[0004]

According to the above-mentioned conventional technique for pulverizing animal blood, not only a large and complicated device is required, but any one of heat quantity, cost, labor and time is required. A great deal of money was needed. Also, if the blood discharged from the animal is left untreated, it deteriorates due to decay and emits a foul odor.
There were a number of problems, such as being a source of pollution if it spilled into a river. Furthermore, although a large number of useful substances are contained in the discharged blood, the conventional treatment method described above has a problem that the effective component is destroyed and cannot be effectively used.

The basic invention (Japanese Patent Application No. 4-270910) already proposed by the applicant of the present application is capable of solving all the problems of the prior art.
Continuing the research, we obtained the mixing ratio of animal bleeding and highly active calcium oxide that can more efficiently pulverize animal bleeding, and further speed up the pulverization reaction and add highly active calcium oxide. A method for producing animal blood drainage powder that can be reduced in amount was studied.

[0006]

As described above, the present invention further studies the basic invention proposed by the applicant of the present invention,
It is possible to more efficiently powder animal bleeding blood. Obtain the mixing ratio of animal bleeding blood and highly active calcium oxide, and further speed up the powdering reaction and reduce the amount of highly active calcium oxide added. The present invention provides a method for producing an animal blood drainage powder that can be used.

That is, according to the present invention, the egg shell is kept at 900 ° C.
An animal drainage powder obtained by reacting highly active calcium oxide obtained by firing at 1500 ° C. with animal drainage. Further, the animal drainage powder is characterized by being obtained by reacting highly active calcium oxide obtained by firing egg shells at 1200 ° C to 1300 ° C with animal drainage.

Another invention of the present application is an animal drainage powder obtained by reacting animal drainage, highly active calcium oxide, and an organic acid or a salt thereof. In the above, the highly active calcium oxide is used in the eggshell at 900 ° C to 1500 ° C.
It is obtained by firing at a temperature of 1,200 ° C to 1,300 ° C. In the above, the organic acid is one of propionic acid, formic acid, malic acid, and lactic acid, and the salt of the organic acid is one of calcium propionate, sodium propionate, and sodium sorbate. It was done.

Further, the invention of the manufacturing method of the present application is characterized by
A method for producing animal blood drainage powder, which comprises charging highly active calcium oxide obtained by firing at 00 ° C to 1500 ° C and animal blood drainage into a reaction tank, stirring and reacting to form a powder. . In the above, the weight ratio of the blood discharged from the animal to the highly active calcium oxide is 1: 0.5 to 1.5, or 1: 0.7.
.About.1.2.

In another invention of the manufacturing method of the present application, eggshell 12 is used.
A method for producing an animal blood drainage powder, which comprises charging highly active calcium oxide obtained by firing at 00 ° C to 1300 ° C and animal blood drainage into a reaction tank, stirring and reacting to form a powder. . In the above, the weight ratio of the blood discharged from the animal to the highly active calcium oxide is 1: 0.5 to 1.5, or 1: 0.7.
.About.1.2.

Further, the invention of another production method of the present application is characterized in that animal blood drainage, highly active calcium oxide, and organic acid or a salt thereof are introduced into a reaction tank and stirred and reacted to form a powder. And a method for producing animal blood drainage powder. In the above, the weight ratio of the blood discharged from the animal to the highly active calcium oxide is 1: 0.3 to 1.5, or 1: 0.5 to 1.2. In addition, in the above, the highly active calcium oxide is used in egg shells at 900 ° C to 1500 ° C, or 1200 ° C.
It was obtained by firing at ˜1300 ° C. In the above, the organic acid is one of propionic acid, formic acid, malic acid, and lactic acid, and the salt of the organic acid is one of calcium propionate, sodium propionate, and sodium sorbate. It was done.

[0012] In the above, a sufficient reaction is carried out by mixing animal bleeding blood and highly active calcium oxide, or mixing animal bleeding blood and highly active calcium oxide with an organic acid or a salt thereof, and a reaction in a soft and squash state. The product was able to be produced. The product can be pulverized by simply crushing, and a powder having a size of about 100 mesh can be obtained.

The highly active calcium oxide used in the above is obtained by firing egg shells at 900 ° C to 1500 ° C. When the firing temperature is lower than 900 ° C., due to lack of activity, when the obtained highly active calcium oxide is mixed with drained blood, the drained blood becomes a mud-like or solidified product, which cannot be powdered. Can not. When the calcination treatment is performed at a relatively low temperature (for example, when calcination treatment is performed at 1000 ° C. or lower), the reaction rate when the obtained highly active calcium oxide is mixed with discharged blood is slow. When the calcination treatment is performed at a high temperature (for example, when calcination treatment is performed at 1200 ° C. to 1300 ° C.), the reaction rate when the obtained highly active calcium oxide is mixed with the discharged blood becomes faster. On the other hand, even when the firing temperature exceeds 1500 ° C, there is no difference in reaction rate and activity when using the highly active calcium oxide obtained at a firing temperature of 1300 ° C. C. to 1500.degree. C. is preferable. According to the experiments by the inventor, the firing temperature of 1200 ° C to 1300 ° C is most preferable in view of the reaction rate when the highly active calcium oxide obtained by the firing treatment is mixed with the blood.

In the above, the egg shell is heated to 900 ° C. to 150 ° C.
Highly active calcium oxide obtained by firing at 0 ° C. is used, but instead of this, it is also possible to use a product obtained by firing at 900 ° C. to 1500 ° C. a shell or other substance from which pure calcium can be easily collected. it can. However, caution is required because sufficient reaction may not occur unless firing is performed at least at 900 ° C or higher.

In the above, the mixing ratio of the animal bleeding blood and the highly active calcium oxide is such that when the animal bleeding blood and the highly active calcium oxide are reacted alone, the highly active calcium oxide is 0 per 1 part by weight of the animal blood bleeding. 0.5 to 1.5 parts by weight is preferable. If the proportion of highly active calcium oxide is less than this,
The powdering reaction does not occur even after a long time, for example, 24 hours, after mixing. When the ratio of the highly active calcium oxide is higher than this range, no difference can be seen in the powdering reaction. Therefore, from the viewpoint of economy, the upper limit of the preferable mixing ratio is 1: 1.5 by weight. According to the experiment conducted by the inventor, the reaction rate, the reaction time, and the product were obtained when 1 part by weight of the blood discharged from the animal was mixed with 0.7 to 1.2 parts by weight of highly active calcium oxide. It was the best seen from the state of. Therefore, judging from these points, the mixing ratio of the animal bleeding blood and the highly active calcium oxide is such that when only the animal blood bleeding and the highly active calcium oxide are reacted, the high activity per 1 part by weight of the animal blood drainage is obtained. Calcium oxide is 0.7-1.2
Most preferred is parts by weight.

Further, in the above, when reacting the animal bleeding blood with the highly active calcium oxide and the organic acid or its salt, the mixing ratio of the animal bleeding blood and the highly active calcium oxide is 1 part by weight of the animal bleeding blood. On the other hand, the highly active calcium oxide is preferably 0.3 to 1.5 parts by weight. If the proportion of highly active calcium oxide is less than this, it may take a long time, for example, 2 after mixing.
The powdering reaction does not occur even after 4 hours. If the ratio of highly active calcium oxide is higher than this, no difference can be seen in the powdering reaction, so from the economical point of view,
The upper limit of the preferable mixing ratio is a weight ratio of 1: 1.5. Further, in order to complete the pulverization within a relatively short time after mixing, 0.5 part by weight or more of highly active calcium oxide is preferable to 1 part by weight of blood discharged from the animal. Further, similarly to the above, from the viewpoint of reaction rate, reaction time, and product state, it is most preferable that the ratio of highly active calcium oxide is 0.7 to 1.2 parts by weight to 1 part by weight of animal blood drainage. .

It is possible to lower the mixing ratio of highly active calcium oxide by allowing an organic acid or a salt thereof to participate in this reaction, as compared with the case of reacting only the blood discharged from an animal with highly active calcium oxide. This is probably because the highly active calcium oxide is alkaline, while the organic acid or its salt is acidic. It does not matter if the acid is added. Organic acids or salts thereof are particularly preferable.

The organic acid or its salt to be added is not particularly limited. The product animal drainage powder can be used as feed or fertilizer. For example, the type of organic acid or its salt to be added may be determined in consideration of the use of such product animal drainage powder. it can. For example, when the product animal drainage powder is used for feed, the organic acid and its salt specified in the feed additive can be added. In this case, as the organic acid, propionic acid,
Formic acid, malic acid, lactic acid, etc. can be added, and as salts of organic acids, calcium propionate, sodium propionate, sodium sorbate, etc. can be added.

The mixing ratio of this organic acid or its salt may be about 0.1 part by weight based on the total weight of the animal drainage and highly active calcium oxide to be mixed.

In the above-mentioned production method, the stirring performed after charging into the reaction tank is not always essential, but in order to uniformly mix the bleeding blood and the highly active calcium oxide, it is preferable to perform slow stirring. preferable.

[0021]

According to the present invention, when the blood discharged from the animal and the highly active calcium oxide are added and mixed, or the blood discharged from the animal and the highly active calcium oxide and the organic acid or the salt thereof are added and mixed, a few minutes to a dozen minutes After that, an exothermic reaction is rapidly started, and after several minutes to several tens of minutes, a reaction product which is in a soft and squash state is formed. The reaction product produced can be ground very easily. Therefore, the produced reaction product is simply pulverized, and a powder product is produced without using a drying means or the like.
The product can be made into a product through a process such as packaging. However, the reaction speed time differs depending on the temperature of the outside air, and in summer and winter, a difference of several hours occurs. The generated blood-exhaust powder contains the active components of blood-exhaust without being denatured.

Further, by causing the organic acid or its salt to participate in the reaction between the blood discharged from the animal and the highly active calcium oxide, the amount of highly active calcium oxide required for pulverization is reduced, and the time required for pulverization is shortened. Can be made.
