Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optimum additive to be added to feed and fertilizer and a method for producing the same.

[0002]

2. Description of the Related Art Fertilizers applied to fields and feeds given to livestock such as chickens and cows are widely used. In recent years, due to the spread of pesticide-free vegetables and the like, fertilizers have been improved more and more so as not to contain substances that are harmful to the human body, and feeds are also the same.

However, since such fertilizers and feeds do not contain the above-mentioned harmful substances, there are problems that mold is likely to occur and that harmful insects come to eat. In addition, there has been a demand for an additive that can supplement the lacking components.

[0004]

SUMMARY OF THE INVENTION In consideration of the above facts, an object of the present invention is to provide an additive which can maintain the quality of feed and fertilizer and is harmless to the human body, and a method for producing the additive.

[0005]

The invention described in claim 1 is characterized in that the bran vinegar is impregnated into the bran at a weight ratio within the range of 5% to 30% to be granulated.

The wood vinegar is a low-purity acetic acid solution obtained when producing charcoal. When the weight ratio of the wood vinegar contained in the additive is 5% or less, the granulated additive tends to be moldy, and when it is 30% or more, the viscosity becomes too high and the granulation is difficult to granulate. When granulating, charcoal powder or the like may be mixed in to adjust the viscosity.

According to the invention of claim 1, since the wood vinegar solution is sufficiently impregnated in the additive, it is easy to cause mold in the feed and the fertilizer by mixing the additive in the feed and the fertilizer. Can be prevented.

Further, the disinfecting effect (bactericidal effect) of cresol contained in the wood vinegar can prevent harmful insects from coming in to eat fertilizer or feed. Therefore, it is also effective to sprinkle it in a pot as a pest repellent.

[0009] Furthermore, this additive is rich in the mineral content contained in the wood vinegar and has a high nutritional value due to the bran. preferable. Further, it is known that wood vinegar is harmless to crops and livestock as well as the human body.

Further, since the wood vinegar has a deodorizing effect, when the feed containing this feed additive is fed to livestock (chicken, cow, etc.), the bad smell of feces can be suppressed. In recent years, housing often stands around the poultry house along with the construction of the residential land. In this case, the management of the poultry house becomes difficult in order to suppress the bad odor of chicken manure, but the feed additive according to claim 1 was added. Feeding chickens reduces the bad smell of chicken droppings, which facilitates the management of the poultry house.

When producing charcoal, the demand for charcoal vinegar is lower than the demand for charcoal, so it may be necessary to reduce the production rate of charcoal. However, according to the invention of claim 1 As the demand for coal increases, it also has the effect of increasing the production rate of charcoal.

The invention according to claim 2 is characterized in that the bran is rice bran.

Since rice bran is produced in factories and the like due to the trend of unwashed rice, it is easily available in large quantities for industrial use. Therefore, the invention according to claim 2 facilitates mass production of additives. As the rice bran, a trade name "rice no Sei" available from Toyo Seiyaku Co., Ltd. may be used. By the way, depending on the oil content of the bran,
When the bran is kneaded, it becomes a dumpling-like viscous body. It is relatively easy to granulate this to a predetermined size. Therefore, in the invention according to claim 3, a kneading step of kneading the bran and the wood vinegar to obtain a viscous body in which the bran is impregnated with the wood vinegar, and a granulating step of granulating the viscous body , To produce an additive.

As a method of impregnating the rice bran with the wood vinegar, it is possible to spray the wood vinegar with the granulated rice bran.

However, even if the wood vinegar is sprayed, the granulated rice bran is not uniformly impregnated, so that the wood vinegar is not sufficiently impregnated, and the weight ratio of the wood vinegar impregnated is controlled. It can be difficult. In addition, when spraying (spraying), it is considered that good components such as minerals contained in the wood vinegar solution are scattered into the air and are not absorbed so much by the rice bran.

By kneading as in the invention described in claim 3, such a difficulty can be avoided and a granulated additive can be produced while the good effect of the wood vinegar solution remains sufficiently. . Moreover, the weight ratio of the wood vinegar solution impregnated into the bran can be easily controlled, and the bran can be uniformly contained in the bran.

According to a fourth aspect of the invention, in the kneading step, the bran and the wood vinegar solution are put into a mixer and kneaded.

As a result, the kneading step can be carried out remarkably easily using a general-purpose device.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to embodiments. The additive according to one embodiment of the present invention is a fertilizer additive 13 (see FIG. 4) obtained by kneading and mixing rice bran and wood vinegar, granulating, and naturally drying.

In order to produce the fertilizer additive 13, the rice bran 14 and the wood vinegar solution 16 are put into a container 22 at a weight ratio of 2: 1 using a mixer 20 as shown in FIG. As the wood vinegar solution 16, one having a pH of about 3 is used. Rice bran 14
Uses rice bran produced by non-washed rice treatment.

When the blades 24 of the mixer 20 are rotated to mix, the lipid contained in the rice bran 14 forms one viscous substance 28 in the container 22 (see FIG. 2). Since this viscous body 28 is manufactured by kneading, it is uniformly impregnated with wood vinegar.

The viscous body 28 is granulated by using a general-purpose extrusion molding machine 30 as shown in FIG. The extrusion molding machine 30 used here has a tubular portion 32 and a cylinder 34 that moves back and forth in the tubular portion 32, and a granular material of a predetermined size is formed on the tip side of the tubular portion 32. Thus, the mesh-shaped forming plate 36 is attached.

By inserting the viscous body 28 into the cylindrical portion 32 and pushing the cylinder 34, the viscous body 28 is formed into a molding plate 36.
Extruded with a predetermined cross-sectional size from the
