Description of the Related Art When producing compost using agricultural waste such as rice straw, grain stalks, and mown grass, livestock waste and water content must be increased in order to promote fermentation of the compost material. A method of mixing vegetable waste and the like, which is often used, is used.
It is also considered effective to periodically spray miscellaneous wastewater during the production of the compost and supply the water required for fermentation. In order to further promote the fermentation of the compost, by using a means such as periodically turning the compost to homogenize the fermentation, a large amount of air is also supplied to the inside of the compost layer, and aerobic bacteria Means for promoting the growth of microorganisms and microorganisms and producing compost are used.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the apparatus of the present invention will be described with reference to the illustrated example. The example shown in FIG. 1 shows a schematic configuration of a compost production apparatus 1 of the present invention,
Compost material A from the input chute 15 provided at one end of
The auxiliary additive material B and the fungus supply member C are charged, and the compost material A is transported while being stirred in the treatment tank 10 by the stirring / transporting means 20, and the fully-composted compost is discharged from the discharge port 17. Since the fungus supply member C is still mixed with the mature compost D discharged from the discharge port 17, the separation device 8
The matured compost and the fungus supply member are separated by using and the matured compost is stored in the compost storage tank 9, and the fungus supply member holding a large amount of fungi is repeatedly used.

As the stirring / transporting means 20 disposed inside the processing tank 10, a screw device is used. A flight member 23 having an arbitrary shape is projected around a screw shaft 21 formed as a hollow shaft. The screw shaft 21 is provided with air ejection holes 22 of an arbitrary size at predetermined intervals. Air supplied to the screw shaft 21 is supplied from the heating / humidifying device 5 through the air supply pipe 6 to the screw shaft 21 through air supplied with heating or humidification or the like. Vent hole 22
From the tank to promote compost treatment.

The composting material A to be composted by the composting apparatus 1 of the present invention includes, for example, agricultural waste and livestock waste, as well as waste such as garbage discharged from homes. When agricultural waste is used as a material, it is possible to use rice straw, grain stalks, cut grass or vegetable waste, and the like. In addition, the livestock waste and the agricultural waste are mixed and used as a compost material, and for materials having a relatively low water content such as rice straw, grass, and leaves, the waste and water content of the livestock barn are reduced. It is easy to adjust the amount of water in the compost material by mixing a large amount of vegetable waste and the like. Then, as a material containing a large amount of microorganisms such as Bacillus subtilis, natto, yeast, and lactic acid bacteria, and a large amount of various microorganisms, the previously manufactured ripe compost is appropriately mixed with the compost material, thereby composting the compost material. Processing efficiency can be improved.

In addition to the compost material A, a compost production device 1
In order to promote the growth of microorganisms and improve the quality of the produced compost, use of calcium component, porous inorganic material, any other inorganic and organic components as auxiliary additive material B Is valid. As the calcium component, for example, finely crushed shells can be used, and in addition, coral powder and the like can also be used. When a large amount of the calcium component is mixed, a large amount of the calcium component can be contained in the fully matured compost. Further, it is assumed that carbon dioxide and calcium oxide generated by compost fermentation react with each other to fix the carbon dioxide as calcium carbonate, and it is considered that a large amount of carbon dioxide can be prevented from being discharged from the treatment tank.

The porous inorganic component to be mixed into the auxiliary additive material may be a porous inorganic material having a large amount of voids therein, such as zeolite and perlite used as a general soil conditioner. Or a material obtained by subjecting these materials to heat treatment at 300 to 400 ° C. and then processing into powder. Further, in order to activate the growth of microorganisms inside the device, a small amount of activated carbon, a magnet component or the like can be mixed into the auxiliary additive material. The various auxiliary additive materials as described above are components added to general soil conditioners, and by adding the inorganic porous component to the compost material, the efficiency of compost fermentation of the compost material is improved. And improving the effectiveness of the compost by adding a soil conditioner component to the produced compost.

As the fungus supply member C to be mixed with the compost material A, for example, a ceramic as disclosed in Japanese Patent Application Laid-Open No. 9-99291 can be used. The ceramics are mainly composed of an inorganic porous material such as zeolite and a porous material rich in a calcium component such as coral, and activated carbon and a magnetic substance are mixed at a predetermined ratio, and a polysaccharide is used as a binding material. It is constituted as a ball or an elliptical mass having a diameter of 3 to 5 cm, and is heated at a temperature of about 350 ° C. The ceramic mass produced as described above contains a very large percentage of minute pores and spaces of each material, minute gaps generated by firing the bonding material, and the like. It is said. That is, in the ceramic mass, a large amount of microorganisms and nutrients required for the growth of microorganisms can be held in the internal space.

The mass of ceramics used as the fungus supply member C is heat-treated and then converted into polysaccharides such as oligosaccharides, organic acids such as malic acid and kojic acid, nutrients such as nucleic acid-related substances, and hot springs. It is immersed for a predetermined time in a solution in which the contained trace element components and the like are mixed, so that the solution components enter the inner space of the lump. After the treatment, the fungus supply member is immersed in a solution of a microorganism having a property of promoting compost fermentation, such as Bacillus subtilis, natto, yeast, and lactic acid bacteria, and penetrates a gap inside the fungus supply member. When a microorganism having a property of reducing nitrate nitrogen is added together with the microorganism, the compost fermentation of the compost material can be further promoted. The microorganism is a new bacterium that is effectively used in the production of compost under the name `` Bamboo bacillus, '' which has the property of reducing nitrates that cause malodor and emitting coffee odor by itself. This can prevent the generation of offensive odor. Further, the bacterium has characteristics such as containing an antibacterial chitin that suppresses the growth of harmful microorganisms,
The produced ripe compost has a high nitrogen content and contains a large amount of components that contribute to the growth of effective microorganisms such as other actinomycetes.

The fungus supply member C manufactured as described above is mixed with the compost material A together with the auxiliary additive material B from an input chute at an appropriate ratio, and is agitated and transported by the agitating and transporting means in the treatment tank. Then, compost fermentation is performed while supplying appropriate temperature and humidity for the growth of microorganisms. At the time of the compost fermentation, useful microorganisms are supplied from the fungal supply member C to the inside of the compost material at any time. Under the environment of the compost fermentation, the nutrient components contained in the fungal supply member are used to provide the fungal supply member. Large amounts of microorganisms grow inside.
In addition, the microorganisms that have contributed to the compost fermentation are transferred to the fungus supply member and multiply inside the fungus supply member together with the microorganisms that were included from the beginning. Is contained in large quantities,
It is in a state where the growth of microorganisms is actively performed.

Therefore, in the present invention, the fungus supply member discharged from the terminal end of the treatment tank and contained in the matured compost is
It is collected separately from the compost and supplied from the input chute together with the compost material so that it can be reused. Note that the fungus supply member C is formed as a relatively hard lump of ceramics, does not break even when it hits the flight member of the stirring / transporting means, and can maintain the shape of the lump repeatedly. However, during compost fermentation, calcium components and the like may be used by microorganisms, or some may be dissolved by organic acids and the like. Then, since the material gradually becomes thinner or crushed, the material having a certain size or less is reduced to soil together with compost, so that the fungus supply member can be effectively used as a soil improving material.
