Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for producing organic fertilizer, and more specifically, a novel method for producing organic fertilizer that also functions as a soil conditioner by processing foul-smelling manure in a surprisingly short time. It is about the method.

Conventionally, many methods have been proposed for producing organic fertilizers using human excreta as raw material. However, the production methods that have been proposed so far require a process of biologically treating the excrement and a process of stirring and drying it under hot air, resulting in low productivity and high equipment and fuel costs. It had to be extremely expensive.

In addition, in the livestock farming industry where livestock such as cattle, pigs, and chickens are raised, manure and urine excreted by livestock must be disposed of promptly in order to prevent bad odors. However, with conventional organic fertilizer production methods that require biological means, it is virtually impossible to reuse stored manure as a raw material for organic fertilizer due to equipment and processing time considerations, and the only option is to dispose of it. Nakatsuta.

The present invention was made in view of the above-mentioned drawbacks of the conventional method of producing organic fertilizer using manure.When a certain proportion of quicklime is mixed with manure, it is sufficient to boil down the manure itself. Focusing on the fact that heat of reaction is generated, we use this heat of reaction to eliminate the use of thermal power, and also to add efficiency to the organic fertilizer produced as a soil conditioner, and to impregnate it with chlorophyll. This is intended to prevent bad odors during manufacturing and the product itself.

That is, in the present invention, quicklime is added to human excrement, and the heat of reaction generated at the time is used to boil and knead it until it becomes a clay-like solid, and then this solid is mixed with an alcoholic solution of chlorophyll. This relates to a method for producing organic fertilizer, which is characterized in that it is chopped to a required particle size while being added, and then dried. In the method of the present invention, human waste (human, cow, pig, chicken, etc.) that has not undergone any fermentation or other biological treatment can be prepared into a gel form and used as it is as a starting material. . As the quicklime, agricultural quicklime may be used. In this case, the appropriate mixing ratio of manure and quicklime is approximately 1 part of quicklime to 20 parts of manure, expressed in weight ratio.

When manure and quicklime are kneaded, water _H2O contained in the manure acts on quicklime _CaO , generating strong heat and converting it into slaked lime Ca(OH).

CaO + H ₂ O = Ca (OH) + 15.2 Kcal The substance is boiled down and kneaded into a clay-like solid by the reaction heat (approximately 120°C) generated at this time.

The kneaded solid material is then chopped to the required particle size (average particle size of about 5 mm) using a chopper device or other means while being sprinkled with an alcoholic solution of chlorophyll (5%), air-dried, or dried using a drying agent or other non-thermal method. It is dried and turned into organic fertilizer.

In addition, in the above method, the processing time from the input of excrement to the chopping step can be performed in about 15 minutes.

As explained above, in the method of the present invention, organic fertilizer can be produced in a short time without the need for treatment by biological means or hot air treatment using thermal power. It is extremely advantageous in terms of cost and productivity, and since the produced organic fertilizer contains slaked lime, it also has the effect of improving acidic soil, and exhibits excellent properties as a fertilizer.

In addition, in the method of the present invention, since an alcoholic solution of chlorophyll is added, the surface of the produced organic fertilizer is impregnated with chlorophyll, so there is no bad odor at all, and even if it is left outdoors, it does not attract flies. No maggots appear.

As described above, the method of the present invention has many advantages that cannot be expected from conventional methods, and has great industrial utility value.
