Abstract

The present invention is intended to contribute to the recycling of resources by powdering the amino acid fermentation by-product (liquid) to increase the useful value as an organic fertilizer raw material, recycling the resources discarded by-products.

The present invention relates to a powder fertilizer composition obtained by mixing and stirring 20 to 70% by weight of an amino acid fermentation by-product (liquid), 5 to 40% by weight of an iron hydrate, and 10 to 50% by weight of an alkaline substance.

The present invention uses a self-exothermic reaction through the mixing of the iron hydrate and alkaline substances to reduce and aggregate the moisture of the amino acid fermentation by-product (liquid) and pulverize it to undergo a powdering process that does not require the input of external energy, and is mostly discarded. It is possible to recycle the amino fermentation by-product (liquid), and to replace some of the expensive organic raw materials and to provide environmentally friendly fertilizer rich in nutrients.

Description

A powder fertilizer composition byusing a by-product of amino acid fermentation}

1 is a process chart of the powder fertilizer according to the present invention.

The present invention relates to a fertilizer through the powdering of the amino acid fermentation by-product (liquid), more specifically, by mixing the iron hydrate and an alkaline substance in the amino acid fermentation by-product (liquid) to promote moisture removal and powdering through self-heating A powder fertilizer composition with no input of external energy.

In general, the amino acid fermentation by-product (liquid) generated as a by-product from seasoning fermentation manufacturing processes such as sodium glutamate (MSG), sodium 5-inosinate (IMP), sodium 6-guanylate (GMP) and lysine manufacturing process It is abundant in organic matter and also rich in fertilizers such as nitrogen and potassium, so it is used as liquid fertilizer or granular fertilizer granulator, feed additive, etc. to recycle it.

Typically, the amino acid liquid ratio prepared by using the amino acid fermentation by-product (liquid) is simply packaged and sold as an amino acid fermentation by-product (liquid), used as granules for granular fertilizer, or by mixing an inorganic powder such as zeolite and an organic powder. It is usually used as granular fertilizer of granule type using pellet production or drum pelletizing.

However, when the liquid fertilizer is used, since the liquid fertilizer itself is acidic (pH 3-4), it is difficult to make a large amount of acid by making the soil acidic, and neutralize and concentrate the liquid fertilizer to be sprayed onto the inorganic and organic powder to produce granular fertilizer. In this case, the amount of use is limited, a lot of energy is required, and the manufacturing cost increases, which is accompanied by economic problems due to cost burden. For this reason, the majority of amino acid fermentation by-products (liquid) is a situation in which a large amount is discarded by ocean dumping.

Accordingly, the present invention is to provide an environmentally friendly powder fertilizer composition which is inexpensive and can be used as a fertilizer by using the amino acid fermentation by-product (liquid) discarded to solve the above problems.

The powdering of the amino acid fermentation by-product (liquid) mentioned in the present invention is to solve the cost increase factor of fertilizers or feed companies due to the price increase of organic fertilizer raw materials, and to achieve the purpose of recycling the discarded resources.

In the present invention, the content of the amino acid fermentation by-products (liquid) can be adjusted freely, and thus the component content can be freely adjusted. Through this, it can be used as the main raw material of the amino acid fermentation by-product fertilizer and mixed organic fertilizer, and mixed oil and manure, compost, green primary compost It can be used as an auxiliary material to reduce the price of fertilizers and to produce environmentally friendly and high functional fertilizers.

Fertilizer composition of the present invention is made by mixing and stirring 20 to 70% by weight of the amino acid fermentation by-product (liquid), 5 to 40% by weight of the iron hydrate, 10 to 50% by weight of the alkaline substance, wherein the mixing of the iron hydrate and the alkaline substance It induces self-heating through and uses this heat to powder the water in the amino acid fermentation byproduct (liquid) without input of external heat energy.

The energy obtained in the above-mentioned combination is accompanied by a high exotherm of 100 ° C. or higher, thereby drying the moisture in the amino acid fermentation by-product (liquid) and performing the reaction in a space capable of heat dissipation to suppress the reaction heat from flowing out. .

The alkaline material used in the present invention may use calcium oxide, magnesium oxide, slag powder or mixtures thereof, and it is preferable to use magnesium oxide (goto) or calcium oxide (quick lime) which is easy to purchase and inexpensive. The iron hydrate is preferably at least one iron hydrate selected from the group consisting of ferrous sulfate and its hydrates.

Hereinafter, the present invention will be described in more detail with reference to Examples. These examples are intended to illustrate the present invention in detail, but the scope of the present invention is not limited to these examples.

Example

As briefly shown in Figure 1, amino acid fermentation by-product (solution) (origin: CJ, object, BASF, water content: 30-60%) 560 g, calcium oxide (quick lime) 80 g, ferrous sulfate (monohydrate and Heptahydrate) 210g, 150g of magnesium oxide (goto) was mixed and stirred, and the drying and coagulation reaction was induced for 4 hours while the internal temperature was over 100 ° C by exothermic reaction. Then, the mixture was cooled to room temperature and ground to powder. At this time, the moisture content of the powder was 21%.

Experimental Example

In order to analyze the physical and chemical properties of the powder prepared according to the above example, it was analyzed by requesting KG Astec (formerly Cheil Analysis Center) located in Bucheon, Gyeonggi-do.

The results are shown in Table 1 below.

As described above, the present invention utilizes self-exothermic reactions of iron hydrates and alkaline substances to make the amino acid fermentation by-products (liquid) go through a powdering process requiring no external thermal energy. It is possible to provide environmentally friendly fertilizers and fertilizer raw materials, which have no significant difference in selling price compared to the conventional products.

In addition, by mixing the organic fertilizers such as coke pit, pitmouth, rice bran, castor gourd, palm leaf and the like to the powder prepared above to enable the production of secondary products containing high organic matter content and rich in fertilizer components, amino acid fermentation by-product fertilizer And organic fertilizers such as mixed organic fertilizers can be used as the main raw materials.
