It relates to a manufacturing method.

Generally, sludge deposited in clean areas or streams varies depending on the region, season, degree of denseness of surrounding forests, and forest species, but the moisture content is about 96 ~ 99.5%. Consists of more than% natural fermentation microbial cells.

In places such as Andong Dam and Imha Dam, which are located in clean areas and used as water supply dams, the existence of the above-mentioned sedimentary sludge is an obstacle in purifying water, so the sludge is stabilized and mechanically dehydrated and landfilled. As it is very high, it is very difficult to treat a large amount in a water treatment plant. As a result, the local government purchased the sludge for 3,400 won per ton from specialized collectors as of 2004, and even in selecting a landfill without using it for a specific purpose. Since it is necessary to collect the intentions of the residents, it is difficult to select the situation.

       On the other hand, feed is food for the purpose of supplying nutrients to animals such as livestock, poultry, and farmed fish. In the livestock industry, feed costs account for about half of production costs.

       In general, feed is classified into rich feed and irradiated food according to the nutritional value. The rich feed is a feed containing a small amount of fiber and containing a lot of energy and protein, whereas the feed is a high crude fiber and a low energy and protein. Feed. In addition, feed may be classified into fat and fat feed, and fat and fat feed is necessary for livestock to maintain life without producing activities. Production feed is used for lactation, fattening, motherhood, It is necessary for production activities such as laying, pregnancy, development and ministry. In terms of marketability of feed, it can be classified into self-feed and purchase feed, and can also be classified according to livestock.

       In addition, the method of feeding the feed is restricted to the specific feeding method according to the animal's nutrient requirements, the feeding method to allow the animal to feed at random, and the restriction on some birds. There is a forced salary law that applies to the law. In theory, the limited-feeding method is reasonable in terms of efficiency, but it is sometimes used in breeding for the purpose of raising livestock management.

       However, ammonium phosphate or superphosphate, which is often used as a growth accelerator by fermentation accelerators and inorganic salt supplementation in conventional livestock feed, has been discharged to stools except for 30 to 40% utilization of livestock or poultry. There is a serious problem that causes soil pollution, inhibits microbial activity in the soil and enters the river water due to the settling, causing harmful effects such as green algae.

       From the above-mentioned matters, many efforts have been made to find an effective application field of the conventional sewage sludge, while it is possible to reduce the manufacturing cost in the feed, resulting in high economic efficiency, and acid fixation of the soil even when the residue is disposed of.

First, the main raw materials used in the composite organic feed and a method for producing the same according to the present invention will be described.

One of the main raw materials used in the feed according to the present invention and the method for producing the same, the clean lake or the sedimentary sludge of the stream is mainly from the corrosive soil around the lake or the river, and the microorganism cells that decompose it by the flow of rainwater and the like. Is generated by

Organic matter in the soil can be divided into enzymatic organic matter (formal organic matter) remaining after the animal's fluid is not decomposed, and corrosive matter (leafy or amorphous organic matter) formed by the decomposition of the animal's fluid. Can be.

Corrosive is a brown or dark brown material that is hydrophilic and is a chelate colloidal material with excellent cation adsorption capacity. It is generally adsorbed to soil particles and is a collection of various materials. Depending on the type of humin (humin), fulvic acid (fulvic acid), humic acid (humic acid).

Humic acid is a caustic fraction that is water insoluble under acidic conditions below pH 2 but is water soluble under higher pH conditions and is a major extractable component from humus soil. The color is dark brown or black. Fulvic acid is a caustic fraction that is water soluble under all pH conditions and is a component remaining in the aqueous solution after removal of humic acid by acidification, the color being yellow or yellowish brown. Humin, on the other hand, is a caustic fraction that is water insoluble under all pH conditions including alkali, and the color is black.

The constituents of the corrosive are composed of polymer polymers which are closely related to each other but are not completely identical, and there are differences in molecular weight, carboxyl, number of functional groups such as phenolic hydroxy, degree of polymerization, and the like.

       Humic acids are complex and heterogeneous aromatic macromolecular mixtures having aliphatic compounds with crosslinks between amino acids, amino sugars, peptides, aromatic groups, and fulvic acids are aromatic and aliphatic structures containing functional groups and heavily substituted with oxygen, The theoretical structural formulas of typical humic acid and fulvic acid are as follows.

[Formula 1]

 [Formula 2]

       The above-mentioned sediment deposit sludge is an organic aggregate consisting mainly of humic acid and fulvic acid as described above, their decomposition products by microorganisms, and decomposing microbial cells, and thus has excellent pharmacological value and is sufficient as an effective and excellent organic feed ingredient. It has potential value.

       Therefore, in the present specification, the term 'spoon sediment sludge' used as a main raw material in the feed according to the present invention and the method for producing the same refers to humic acid and fulvic acid, their decomposition products by microorganisms, and their degraded microorganisms. It is defined as meaning an organic aggregate consisting of cells.

       The organic feed according to the present invention is characterized in that it comprises 0.1 to 60% by weight of organic matter derived from the sewage sludge on a dry weight basis, generally 30 to 60% by weight, based on dry weight Preferably it is 40 to 60% by weight, more preferably 45 to 55% by weight, preferably about 50% by weight, which may be appropriately changed depending on various parameters such as the type of livestock or poultry, the intended purpose, of course. to be.

       Vegetable by-products include wheat bran as a by-product of wheat milling, wheat middling, red-dog, rice bran as a by-product of rice milling, gluten produced during the manufacture of corn starch, baking and confectionery. Flakes such as crumbs, molasses as a by-product of sugar processing, and whey as a by-product of dairy processing.

       Wheat flour by-products produce about 25% in the milling process of wheat. Generally, high fiber content results in low energy but high protein content. It is called bran, wheat middleling, and redduck in the order of milling.

       Wheat bran is high in fiber and low in energy but is similar to wheat in protein content and protein composition. Since bran is bulky and low in energy, it is generally used to limit growth without reducing feed intake. However, when added in large quantities, there is a risk that the litter will be wetted by feces. Steam pelletization can increase energy consumption by 10% and phosphorus availability by 20%.

       Wheat middlelings have a higher protein content than wheat, but have a 20% lower energy content.

        Redduck, also known as wheat screening, is a by-product of debris from wheat milling. Therefore, it contains broken wheat and weed seeds. The higher the content of wheat, the higher the feed value and the composition is similar to wheat.

        On the other hand, corn gluten is a by-product of corn starch making, which is roughly divided into corn gluten meal and corn gluten feed. Corn gluten wheat has a high protein content of about 40%, whereas corn gluten The feed contains shells, which is as low as 20%. Corn gluten has the disadvantage of being absolutely lacking in lysin, but Xanthophyll content is more than 300mg / kg is particularly excellent in broilers and laying hens.

        In addition, rice by-products are by-products from the production of white rice and are called rice bran, and rice bran is roughly 30% polished grain and 70% is bran. Sometimes divided into polishing and branch. Polishing has a very high fat content and a low fiber content, whereas a brand has a low fat content and a high fiber content. Rice bran has a high fat content of about 6-10%, so when left at room temperature for 10-12 weeks, 75-80% of the fat becomes rancid and free fatty acid. By adding about 250ppm of the same antioxidant or by extrusion at 130 ℃ can prevent the rancidity of fat, in some cases can also use a degreasing rice bran extracted fat.

        Rice bran has a high content of trypsin inhibitor and phytic acid, and it is reported that the use of more than about 40% will reduce feed efficiency and decrease the growth rate. The trypsin inhibitor described above can be easily destroyed by heating.

        In addition, phosphorus in rice bran is known to be useful only about 10% in the chicken world and its usefulness increases with age. In order to increase the usefulness according to age, the excess Ca is added to the sexual system so that the Ca: P ratio is imbalanced and the growth rate is increased, because the availability of phosphorus increases.

        Confectionery is a crumb that occurs during the confectionery or baking process, which can also be used as feed, and its content can vary depending on the ingredients used. In reality, if a large quantity is available, it is enough for feed. It should be noted that salt content may be added during the confectionery or baking process.

        Molasses is a by-product of the sugar process and has a low energy content and high potassium content, which is easy to cause diarrhea. However, the molasses's feed value increases its food intake by improving palatability.

        Whey can be used to dry scum from dairy processing. Whey contains a large amount of lactose. However, although lactose is rarely used in poultry, lactose has been reported to have an effect on controlling Salmonella spp.

        Vegetable by-product raw materials as exemplified above include wheat bran as wheat milling by-product, wheat middleling, redduck, rice bran as a by-product of rice milling, gluten produced during corn starch production, confectionary in baking or confectionery process, as a sugar processing by-product. Molasses, whey as a dairy processing by-product, etc. may be used alone or in any combination of two or more as needed, and in addition to the exemplified types, a variety of arbitrary types known in the art may be selected and used, or Of course, it can also be used by mixing the by-product raw material in any combination ratio, this is also within the scope of the present invention.

        When the above vegetable by-product material is used in the preparation of the composite organic feed, it is 30 to 60% by weight, preferably 30 to 50% by weight, more preferably 35 to 45% by weight, based on the total weight of the organic organic feed. Is used.

Polymerized calcium phosphate (Ca ₆ P ₆ O ₂₁ 2Ca ₂ CN ₂ ) not only performs an excellent function as a fermentation accelerator and as a growth accelerator by inorganic salt supplementation, but also significantly improves the utilization rate (digestion rate) of livestock or poultry. At the same time, there is little concern about causing soil pollution due to soil fixation after being discharged to the stool, so that even if it enters river water due to cetal, there is little fear of causing harmful effects such as green algae.

       The amount of the polymerized calcium phosphate is 3 to 15% by weight, preferably 5 to 12% by weight, more preferably about 8 to 12% by weight, based on the total weight of the organic organic feed.

       On the other hand, the addition of phosphate instead of polymerized calcium phosphate is the raw material that phosphate ore depends on 100% import, and the component of imported phosphate is regular phosphate, which has to go through multi-step complicated and expensive chemical treatment process. It is not preferable because there is a concern that it may cause environmental problems such as pollution during the treatment of phosphorescent or feed and use of feed, and there is a problem that it is expensive to store 300,000 won per ton as well as storage problems that are weak to moisture.

        However, the present invention does not exclude the use of phosphate or limestone as fermentation accelerator and inorganic salt supplement as long as sludge is used.

        In the present invention, the effect of adding polymeric calcium phosphate to sludge and plant by-products is characterized by the fact that these mixtures have a nutritionally superior microbial substrate in fermentation microorganism growth by supplementing minerals provided by the polymeric calcium phosphate to sludge and plant by-products. ), It is easy to ferment completely, shorten the manufacturing period, and can improve the digestibility, while reducing the amount of feeding to livestock or poultry, and expecting the same or more effect, and about 40% compared to the conventional plant by-product feed. The company will be able to offer economical products with prices as low as 50%.

        On the other hand, in the present invention, there is no need to add a separate demulsifier as a microbial fermentation agent, but may be added if necessary, the addition of such demulsifiers is optional in the present invention.

        In the case of adding the aging agent as the fermentation seed, 3 to 8% by weight, preferably about 5% by weight, may be added based on the total weight of the organic organic feed.

       The microbial fermenters are mainly composed of anaerobic or through anaerobic thermophiles (thermophiles), which are obtained by themselves during composting or maturation or are commercially available commercially.

       In addition, as an optional ingredient that can be used in the feed according to the present invention can be fermented by containing animal feed by-products such as animal feed or poultry meal or blood as slaughter by-products, meat meal, bone meal, non-edible fat, viscera, etc. Of course.

       If animal by-product raw materials are used, the amount is 0.1 to 10% by weight, preferably 1 to 3% by weight, based on the total weight of the organic organic feed.

       Next, a method for preparing a complex organic feed according to the present invention will be described.
