Description

Producing method of tablet-typed by-products compost}

The present invention relates to a method for producing a refined by-product fertilizer processed from a mixture containing by-products such as sludge, food waste, food waste, waste feed, sawdust, sugarcane, and the like, which are environmental pollutants.

Organic fertilizers regulate the content of fertilizer components such as nitrogen, phosphoric acid, and carry to the standard. By-product fertilizers, on the other hand, differ from organic fertilizers in regulating the organic content of their contents. However, organic fertilizers and by-product fertilizers can be included in a broader sense because most of the fertilizers selected as regulatory standards are manufactured through a composting process. Therefore, since organic and by-product fertilizers can be included in a wide range of composting, organic fertilizers, by-product fertilizers and composts may be used interchangeably as synonyms, and the present invention will be used without strict differentiation thereof. .

Types of by-product fertilizers include compost, ripened bran, ash, manure residue, foliar soil, amino acid fermented by-product fertilizer (liquid), dry powder, dry livestock waste (manufactured from waste from livestock slaughter), cooked rice husk and sawdust, There are various materials such as soil microbial agents.

These by-product fertilizers are made from powdered or powdered compost or fertilizer with an emphasis on organic matter, which is too light when applied to lawns, such as golf courses, before reaching the roots of plants before reaching the roots of plants. There is a problem that can not achieve the purpose of the compost application by contacting the animal, including the departure from the application target. In addition, the powdered compost is not easy to apply, there is a disadvantage that the handling is not easy.

Therefore, in order to compensate for this, many people have recently tried to refine, but this effort has repeatedly failed because the sawdust, which is an essential ingredient of conventional compost, lowers the viscosity of the mixed ingredients.

In view of this, the tablet-type fertilizer was previously filed by the present applicant, and the patent application No. 1998-39954 dated Sep. 25, 1998 is a "method of manufacturing a refined by-product fertilizer and a refined by-product fertilizer thereby." "Formulation Types" of Patent Application Nos. 1999-42512 and 42513, filed on October 2, 1999 and newly filed using another byproduct raw material, and Patent Application No. 24732, filed on May 9, 2000. By-product fertilizer and method for producing the same.

The present invention is to develop a tablet-type organic by-product fertilizer by another material different from the contents previously filed by the applicant, the present invention will be described in detail below.

The present invention relates to a method for preparing tablet by-product fertilizers using various by-products, food waste 30 to 50% by weight, 20-40% by weight of nutrients, 10-30% by weight of waste feed, and 5-15% by weight of sludge. Preparing and adding microorganisms such as enzymes to mix them; Primary natural fermentation of the mixture by ventilation for about 10-20 days depending on external environmental conditions; And after the first fermentation, the second step of loading for 40-60 days to ripen; Feed the material into the earthworm to make the earthworm powder (feces) produced 10 to 30% by weight, and here it is 20 to 40% by weight, 10-30% by weight sawdust, 10-30% by weight, sugar cane 5-15 Mixing wt%; And subjecting these mixtures to primary fermentation by ventilating for about 5-10 days at a temperature of 70-80 degrees Celsius and for 10-20 days with stirring; The mixture thus prepared is finally put into a production line to crush the fermentation product, and then, the impurities contained in the crushed fermentation product are sorted, the crushed fermentation product is finished, and the extruded fermentation product is crushed. It is characterized by consisting of a process of cutting the tablets, and finally drying the purified tablets electrothermally.

Other features and detailed descriptions other than those described above will be described in detail later, even if somewhat redundant.

First, in the present invention, food waste is 30 to 50% by weight, preferably 40% by weight (hereinafter, all are% by weight), 20-40% by weight, preferably 30%, waste feed 10-30 Weight%, preferably 20%, sludge 5-15%, preferably 10%, and optionally 5-15% zeolite, preferably 10%.

In addition, the amount of zeolite used in the above-mentioned% was produced in consideration of the mixing ratio of the above-mentioned materials according to the actual experiments, and as a result, it was found to be the best production condition in the preparation of tablet-type organic fertilizer.

Zeolite is for forming a coating layer of tablet fertilizer. This zeolite can be replaced with other coating materials. That is, for example, charcoal may be used.

The coating layer forming material is not limited to the above material, but any other material may be used.

Hereinafter, a method for producing tablet fertilizer using the above-described mixture of materials will be described in more detail.

The ingredient materials of the material mixture according to the present invention are prepared in the above mixing ratios, and microorganisms such as enzymes are added to mix them. The mixture is then subjected to primary natural fermentation by ventilation for about 10-20 days, preferably 15 days, depending on external environmental conditions. Then, after the first fermentation, the fermentation is carried out for 40 to 60 days, preferably for 50 days depending on the season and weather.

The material thus prepared is fed to earthworms to produce earthworm meal (dung). Earthworms are already well known for fertilizing the soil.

Here again, 20-40% by weight (hereinafter,% is all% by weight), preferably 30%, sawdust 10-30%, preferably 20%, stockpile 10-30%, preferably 20% 5-15% sugarcane, preferably 10%.

At this time, the earthworm powder produced by the earthworm is 10-30%, preferably 20%.

These mixtures are then primary fermented by ventilating for about 5-10 days, preferably 7 days, depending on the external environmental conditions at a temperature of 70-80 degrees Celsius, and 10-20 days in a second with continuous stirring. That is, fermentation is continued while stirring. In this case the moisture is about 30-35% by weight. The mixture thus prepared is finally put into a production line to crush the fermentation product, and then, the impurities contained in the crushed fermentation product are sorted, the crushed fermentation product is finished, and the extruded fermentation product is crushed. The tablets were cut to form tablets, and finally, the purified tablets were electrothermally dried to obtain a water content of about 20%.

The extrusion is a method of embedding the contents to be extruded in a cylindrical shape and a screw embedded therein to extrude by rotation of the screw, and in another method, the extruded objects are put in a drum formed with a plurality of holes in the outer periphery, and the drum is By rotating, the inside contents can be configured to be extruded out through the through hole of the drum outer circumference under pressure while being subjected to centrifugal force. The latter have been shown to be more preferred in practical use.

The size of the tablets is 1-10 mm. These organic fertilizers can be selected in various sizes depending on the type of crop used and the purpose of the land. For herbaceous plants such as grass and rice, the smaller the tablet granules (about 2 to 5 mm), the better, and the larger the woody plant such as fruit tree, forest water, etc., the larger the tablet fertilizer (5 to 10 mm). Degree) can be used.

After the tableting step, any one or more materials selected from ocher soil, zeolite (where zeolite is a material providing siliceous component in the fertilizer component, and may use perlite) and charcoal on the outer surface of the refined cut. It may be more rough to form a coating layer consisting of.

Such a coating layer may give an effect of improving the appearance or improving the image in relation to skin contact, vision and smell.

According to the present invention described above, by utilizing the waste, which is a variety of environmental pollutants such as sludge, food waste, animal feed, waste feed, sawdust, sugar cane watermelon, etc. by utilizing the organic fertilizer as a method of using as another organic fertilizer The effect is even higher. Therefore, there is an effect that can further utilize the waste that is discarded or landfilled.

In addition, according to the present invention, there is a feature to provide a method that can be produced even in tablet fertilizer.

The use of oil-based fertilizers using various wastes as described above can improve the fertility of the soil and improve the land's intellect, which can solve problems such as waste disposal problems and weakening of the intellect caused by the use of chemical fertilizers. There is an effect of this article.
