Description

Liquid Manure and Method for Manufacturing the Same

The present invention relates to a liquid fertilizer separated from animal blood as a filtrate.

Animal blood is now used in all of you, and it is also used as feed or fertilizer. When used as feed or fertilizer, additional filtrate is generated in the processing stage, and the generated filtrate has been treated with wastewater. Animal blood is also classified as general waste.

Animal blood for processing into feed or fertilizer is a specific treatment method, which can be processed directly at the source and collected and processed at once. In both cases, the blood is vaporized in the blood to coagulate the protein, that is, in the form of agglomerates. Only solids are processed and used as fertilizer or feed.

It discloses about the fertilization of blood in the form of blood powder disclosed in Korean Patent Laid-Open No. 2002-0022416.

A method of manufacturing organic fertilizer based on blood powder, which comprises the steps of processing powdered blood powder through fermentation, drying and grinding steps, and incorporating bioceramic, sawdust, rice bran, fermentation station and photosynthetic microorganisms into the processed blood powder and It is prepared by a time mixed fermentation step. Fertilizer manufactured in this way has the problem that additional costs to purchase a subsidiary material such as a raw material in the fertilizer manufacturing process.

In other words, in the fertilizer factory, animal blood is mixed with various excipients such as bark, discarded grains, mineral powders, etc. to adjust moisture to prepare a fertilizer.

The maturity step of the fertilizer plant is badly bad smell, and because a lot of solvents are added to match the humidity, there is a problem that the cost of purchasing the solvents increases.

In the fertilizer plant, microorganisms are put into the blood for fermentation and fermentation, followed by adding a large amount of chemically produced elements to produce the four types of fertilizers determined by the fertilizer process standard.

Produced by the method as described above, the blood is a problem that the fermentation ripening period is prolonged, in some cases fermentation ripening is not completed, shipped to the immature stage, caused by the further decomposition of microorganisms during the distribution process The gas creates another problem of inflating the packaging.

In the same vein, the fertilizer plant is difficult to ferment the blood, so the dried blood powder is humidified again to be decomposed into microorganisms, and the liquid blood is decomposed into a complex process to produce liquid fertilizer.

The liquid fertilizer prepared by the above-mentioned manufacturing method is used by diluting a thousand times when used in crops because it is prepared by concentrating the concentration of the liquid fertilizer to a high concentration to reduce the distribution cost. In addition, when chemically prepared elements are added to liquid fertilizers, chemical reactions that react with proteins to form salts result in precipitation of the reactants. The precipitated salts are insoluble and can be nourished as fertilizers when applied to soil. There is no problem.

An object of the present invention is to identify a filtrate that can be used as a fertilizer, without the need to add an additional subsidiary ingredient in liquid fertilizing animal blood, and to provide a liquid fertilizer and a method for producing the same.

The liquid fertilizer of the present invention for achieving the above object is composed of a filtrate which is separated from the animal blood and has nitrogen, water-soluble phosphoric acid, water-soluble girly.

The filtrate evenly contains a large amount of trace elements such as water-soluble boron, water-soluble iron, water-soluble zinc, water-soluble copper, water-soluble manganese, etc., and because it exists as a trace element phosphoric acid, iron, boron, zinc, copper, manganese, screening water-soluble fertilizer When used as a soil is easy to ingest microorganisms.
The filtrate has at least three trace elements in accordance with the fertilizer process specification. In addition, the classification according to the fertilizer process standard is also a liquid fertilizer.

In the case of foliar application cost, nutrient refilling, nutrient solution, or irrigation, flower, and trace element complexes belonging to the fourth type of fertilizer according to the fertilizer process standard, it can be classified as solid and liquid fertilizers. Most fertilizers, except fertilizers, satisfy the nitrogen, phosphoric acid, and garlic content requirements, and only two or more trace elements such as boron, magnesium, manganese, and iron meet the fertilizer process specifications.

However, the filtrate can be registered as a fertilizer permit in accordance with two process standards by itself (flower and microelement fertilizer), and the filtrate is registered as a soil-improving microbial fertilizer by adding microorganisms because it is easy to breed microorganisms. So far, one substance is a comprehensive fertilizer that can register three fertilizers.
Method for producing a liquid fertilizer according to the present invention for achieving the above object, the first step of separating the foreign matter in the animal blood, the second step of boiling the blood separating the foreign matter of the first step and solidifying the solids, The third step of dehydrating the boiled blood of the second step to separate the solids and filtrate, and the fourth step of collecting and storing the filtrate generated after the separation of the solid solution of the third step. It may also further comprise the step of fermenting the stored filtrate.

Microorganisms can be microbially fermented in the fermentation stage, and microbial microorganisms can be composed of one or more selected microorganisms including photosynthetic bacteria, cyanobacteria, and Bacillus genus. Sleep time is required.

Hereinafter will be described in detail a preferred embodiment of the liquid fertilizer and a method for producing the same according to the present invention.

These examples are intended to illustrate the invention and the scope of the present invention is not limited only to these examples.

Example 1

The manufacturing method of the liquid fertilizer according to the present invention will be described below in detail with one embodiment.

A first step of separating foreign substances into the animal blood, a second step of boiling the blood separated from the foreign substances of the first step and solidifying the solids, and a third step of dewatering the boiled blood of the second step to separate the solids and filtrates. And a fourth step of collecting and storing the filtrate generated after the solid-liquid separation of the third step. It may also further comprise the step of fermenting the stored filtrate.

The foreign matter separation of the first step may use a conventional screen or a shaft known in the art, or use a centrifugal separator to remove impurities or foreign substances in the raw blood.
When the foreign matter is separated through the first step, the weight of blood is reduced by about 5%.

The second step is to boil the separated blood to a steam pressure of 5 to 7 kg / ㎠, in the process of infiltrating the steam into the blood condensed vapor in the blood was reduced as much as the foreign matter separated in the first step It replenishes the weight of the blood, making it similar to the amount of blood initially collected. In addition, the blood was coagulated by conventionally heating the blood directly without steaming the blood. However, when the heating is carried out directly, it is pressed against the heating wall so that the thermal conductivity is lowered so that the blood is not coagulated evenly as a whole. Boil the blood with steam to improve it. That is, the boiling conditions are boiled for 30 to 60 min based on 1000 kg of blood, and maintain a vapor pressure of 5 to 7 kg / ㎠.

In addition, the reason for self-cooking by maintaining a steam pressure of 5 to 7 kg / ㎠ is that the collected animal blood is composed of one or more blood selected from pigs, cows, sheep, chickens, ducks, so that the temperature of protein coagulation for each animal species In order to coagulate all animal species, it is preferable to maintain a vapor pressure of 5 to 7 kg / cm 2 under pressure conditions.

Another example of the cooking method is spray drying.

Blood powder can be prepared using a spray-dry method, which is an appropriate method for using plasma and serum separately.

In other words, the spray drying method removes red blood cells and leukocytes, which are serum components, and uses plasma proteins, minerals, water, and inorganic ions. Coagulates plasma proteins and obtains minerals, water, and inorganic ions as filtrates. Can be.

In addition, the spray-drying method must meet the storage conditions to prevent the blood from rot.

The step of dehydrating boiled blood is to separate the blood from solids, and the dehydration condition is preferably maintained at about 10 to 20 min at 1500 to 2000 rpm based on 1000 kg of blood.

The solid-liquid separation step after the dehydration process is a step of separating the solids and filtrate in the form of a solidified mass, the treatment of the generated solids is applied to the method disclosed in the Korean Patent Publication Nos. 1997-000053 and 1997-000052 of the present application The dehydrated liquid, another product, is collected and stored in the filtrate state.

The stored dehydration preferably further comprises a fermentation ripening step.

Fermentation ripening step of the stored filtrate is a dehydration filtrate is required to the fermentation time of 30 to 45 days and the temperature of 35 to 50 ℃ based on 1000kg.

Fermentation aging is a criterion to determine the completion of the method using the smell, when using the smell can be confirmed the completion of fermentation aging even when the intrinsic odor is reduced by more than 80% and the odor of the fermentation of the microorganism is completed.
After fermentation is completed, the liquid fertilizer is stabilized to the extent that no further decay occurs after packaging.

As another example of the fermentation aging step, it was confirmed that the stored filtrate could be used as a fertilizer without fermentation aging. Thus, the liquid fertilizer was applied to the soil in order to check the effect of the filtrate fertilizer not fermentation. As a result, the soil was fertilized and the soil improved. This is one measure to confirm that the liquid fertilizer is stabilized as a fertilizer.

Fermentation ripening step may be made in the temperature range of 35 to 50 ℃, fermentation ripening step has a problem that the progress of the fermentation ripening takes longer when the temperature is less than 35 ℃, if the temperature exceeds 50 ℃ shorten the fermentation ripening period Although it is possible to maintain the temperature excessively, it is preferable to maintain the temperature in the range of 35 to 50 ° C.

Microorganisms can be microbial in the fermentation aging stage.

Microbial agents may be used, and microorganisms that can be used include photosynthetic bacteria and microorganisms corresponding to Bacillus, photosynthetic bacteria have a useful effect of promoting crop growth, and Bacillus microorganisms have a useful effect in controlling pests.

The microorganisms are effective in removing the disgusting odor and preventing the decay, and promoting the fermentation of organic matter obtained by the coexistence of the inoculated microorganism and the indigenous microorganisms in the soil, and the improvement of the soil environment. Because it can preserve.

The liquid fertilizer as a filtrate is sterilized because it is steamed and boiled at the manufacturing stage, so it is possible to grow useful microorganisms that are inoculated without resistance of existing microorganisms when microorganisms are inoculated.
