Description

[0001] The present invention relates to an amino acid liquid fertilizer and protein feed using slaughter blood,

The present invention relates to an apparatus for producing an amino acid solution and a protein dry feed, and more particularly, to an apparatus for producing an amino acid solution and a protein dry feed by solid-liquid separation after pretreating and enzymatically digesting the collected slaughter blood will be.

At present, a total of 982 tons (tons) of pulmonary blood is generated daily at 139 slaughterhouses in Korea, and the amount of blood slaughtered annually reaches 235,562 tons.

Among them, small blood is consumed in most cases in Korea, and blood of chickens and ducks is collected as dried by other by-products in the stomach, dried and recycled partly as feeds. Approximately 75,000 tonnes (311 tonnes per day a year) are being disposed of annually.

However, the amount of slaughter and the amount of slaughtered blood are increasing every year due to the increase in national income. Most of the blood in slaughtered blood is consumed by marine discharges .

However, in the amendment of the Marine Pollution Control Act Enforcement Regulations (Feb.21, 2006) as a result of the entry into force of the '96 Protocol, marine emissions standards for wastes including slaughter blood have been significantly strengthened, and marine emission bans are imminent.

Recently, attempts have been made to recycle slaughter blood as a fertilizer for agriculture. The slaughter blood contains 77.27% of water, 20.89% of organic matter, 18% of total protein, and most of the organic matter content is protein · It corresponds to a waste resource with a very high agricultural value.

At this time, the slaughter blood is composed of about 55% of blood and about 45% of serum, wherein the serum contains about 90% of moisture and about 8% of the protein, and the blood cell contains about 60% of moisture and about 30% Proteins.

As a conventional technique relating to the recycling of slaughter blood, Korean Patent Registration No. 10-0935020 (Patent Document 1) discloses a blood storage tank for collecting and storing waste blood of animals slaughtered at a slaughter facility, The microbes in the liquid microbial blood treatment agent are allowed to react at a temperature of 25 to 35 ° C. for 8 to 12 hours to separate the animal lung blood into the amino acid solution and the pulmonary blood sludge, A water supply device for supplying water to the waste blood treatment tank; a filter means for filtering impurities by filtering the amino acid solution discharged from the waste blood treatment tank; A heater for maintaining the temperature of the blood treatment bath in the range of 25 to 35 DEG C, and a temperature sensor for sensing the temperature in the blood- It discloses a slaughter animal pulmonary blood processing system comprising.

However, in the case of the system disclosed in the above-mentioned Patent Document 1, only the amino acid solution is produced from the waste blood and used as an environmentally friendly fertilizer, and the protein dry food using the protein contained in the pulmonary blood can not be produced.

In addition, the degradation efficiency of biological enzymes degradation of slaughter blood is very low, that is, the protein conversion rate is only about 5%. This is because most proteins in slaughter blood are present in the blood cells, This is because the transfer of intracellular protein substances to the enzymatic degradation substrate is blocked.

Therefore, it is necessary to break down the cell wall of the hemocyte cell before the enzymatic degradation and solubilize the protein in the hemocyte so that it can be used for the enzymatic degradation. The conventional technology such as the system disclosed in the above-mentioned Patent Document 1, There is a problem in that the yield of amino acid fertilizer produced is low.

Korean Patent Laid-Open Publication No. 10-2004-0065201 (Patent Document 2) discloses a method for producing an amino acid liquid fertilizer by adding a strong acid such as nitric acid or sulfuric acid to an animal's body to hydrolyze the protein and neutralize it with calcium oxide .

However, when a strong acid such as nitric acid or sulfuric acid is used, most of the amino acid in the form of a ring is destroyed and only the free amino acid form is present in the decomposition process of the protein. Therefore, the amino acid content of the final product is 2% to 5% And there is a problem that the fertilization is not continuous.

In addition, salt is accumulated and used in the liquid fertilizer during the neutralization process, so that there is a problem that soil contamination due to the accumulation of salts occurs at the time of establishment.

In addition, as disclosed in Korean Patent Registration No. 10-0976085 (Patent Document 3), when waste blood is dehydrated and dried to make blood, and the blood is processed for feed or compost, And there is a problem of an increase in manufacturing cost due to the drying process. In order to reproduce the produced blood components with liquid fertilizer, it is troublesome to liquefy again.

Example

FIG. 1 is a schematic view of an apparatus for producing amino acid juice and protein dry feed using slaughter blood according to an embodiment of the present invention. Referring to FIG.

As shown in FIG. 1, an apparatus (hereinafter referred to as a 'manufacturing apparatus') 10 for producing amino acid juice and protein dried feed using slaughter blood according to an embodiment of the present invention includes a storage tank (40) for converting proteins in the slaughter blood into low molecular weight proteins and peptides by irradiating ultrasonic waves to the slaughter blood; and an ultrasonic treatment device (40) for introducing the proteolytic enzyme into the slaughter blood to decompose the proteins in the blood into amino acids A filter press 60 for dehydrating the primary amino acid material and solid-liquid separation of the solid product and the liquid product, and a micro-filter (not shown) for the solid product transferred from the filter press 60, And a sterilizing / drying device 70 for sterilizing and drying.

At this time, a crusher 30 may be installed between the storage tank 20 and the ultrasonic wave processing device 40. The crusher 30 crushes the slaughter blood to destroy the blood cells of the slaughter blood, And solubilizing.

The reservoir 20, the crusher 30, the ultrasonic treatment device 40, the enzyme reactor 50 and the filter press 60 are connected to each other by a connection pipe 80 having at least one pump (not shown) So that the slaughter blood of the storage tank 20 can be automatically transferred to the filter press 60 through the respective devices.

In addition, a conveyor (90) is provided between the filter press (60) and the sterilizing dryer (70) so that the solid product separated from the filter press (60) is conveyed to the sterilizing dryer .

Here, the storage tank 20 is for storing slaughter blood of livestock such as chickens, pigs, cows, etc. collected from a slaughterhouse, and an agitator (not shown) may be installed therein to prevent solidification.

A known pulverizer may be used as the pulverizer 30, and preferably a cutter type pulverizer having a plurality of cutters may be used so that blood vessels or tendons mixed with slaughter blood transferred from the reservoir 20 Crushing, and destroying hematopoietic cells of slaughtered blood to solubilize proteins in the hemocyte.

In this case, the pulverization time in the pulverizer can be appropriately set according to the degree of solubilization of the proteins in the blood cells of the slaughter blood, and about 10 minutes is suitable for the high-rotation cutter type pulverizer of 5,000 rpm or more.

The ultrasonic treatment apparatus 40 irradiates ultrasonic waves to the pulverized slaughter blood to decompose the proteins of the slaughter blood into low molecular weight proteins and peptides.

At this time, the ultrasonic waves are classified into ultrasonic waves from a frequency of 20 kHz. When the frequency exceeds 30 kHz, cavitation bubbles become large, which leads to ineffective destruction of small-sized hemocytes, dissolution of soluble organic substances due to destruction of biological cells, The frequency range of the ultrasonic wave processing device 40 is preferably 20 kHz to 30 kHz.

In order to improve the efficiency of proteolytic conversion, it is preferable that the temperature of the slaughter blood to be subjected to the ultrasonic treatment is maintained at 40 to 60 ° C. To this end, the ultrasonic treatment apparatus 40 is provided with a heater (41) is preferably provided.

When the temperature of the slaughter blood is higher than 40 ° C, the protein is denatured to weaken the intermolecular bond, thereby facilitating the conversion to a low molecular weight protein or peptide. When the temperature exceeds 60 ° C, coagulation in the blood occurs, I will not.

In addition, in the ultrasonic treatment apparatus 40, the cell walls of the remaining blood cells not destroyed by the pulverizer 30 are also destroyed. This is because the cavitation phenomenon in which fine bubbles are generated when ultrasonic waves are applied to the liquid medium occurs .

In other words, when the generated bubbles are destroyed, high-temperature and high-pressure gases in the bubbles are instantly released, and pyrolysis and strong oxidizing substances such as OH radicals are generated, while the bubbles are destroyed, Due to the effect of high pressure, collisions between the molecules are actively generated. At this time, the cell walls of the hemocyte cells are destroyed by using energy generated in the microbubble destruction.

As described above, according to the embodiment of the present invention, the cell wall of the hemocyte is destroyed in the process of passing through the crusher 30 and the ultrasonic wave processing device 40, so that the protein in the hemocyte is solubilized, It is effective to increase the amino acid conversion of the protein.

In addition, since the pathogenic bacteria in the slaughter blood are killed by the ultrasonic irradiation, degradation efficiency of the enzymes by the pathogenic bacteria is lowered and the end product is prevented from corruption and fermentation, resulting in the prevention of odor and gas generation.

At this time, the ultrasonic irradiation time can be appropriately selected by judging the degree of solubilization of the protein in the blood cell, the degree of conversion of the solubilized protein into the low molecular weight protein or peptide, and the degree of the death of pathogenic bacteria in the slaughtered blood. Is appropriate.

Accordingly, the protein in the slaughter blood is decomposed into amino acids by the enzymatic decomposition reaction, and the primary amino acid preparation is produced in the enzyme reactor (50).

At this time, the completion of the enzymatic decomposition in the enzyme reactor 50 can be judged by using various methods such as elapse of a predetermined time, change in the color of slaughter blood, or measuring the stirrer torque of the enzyme reactor 50.

For example, when the torque of the stirrer reaches a certain value or less, it is determined that the enzymatic decomposition has sufficiently progressed, and the slaughter blood is transferred to the filter press 60 to be described later.

In addition, the temperature of the enzyme reactor can be appropriately selected depending on the amino acid conversion efficiency depending on the enzymatic decomposition reaction time by temperature, and the range of 40 ° C to 60 ° C is suitable.

The amino acid content of the amino acid solution is about 12%, and it contains all 20 essential amino acids.

Further, the solid product produced by the solid-liquid separation of the filter press 60 is preferably a dehydrated cake having a protein content of about 50% and a water content of 50% or less.

The solid product separated from the filter press 60 is transferred to the sterilizing and drying device 70 by a conveying means such as a conveyor 90 and is sterilized and dried in the sterilizing and drying device 70 so that the protein content is 82% And a moisture content of 10% or less. The protein dry food thus prepared is stored in a separate storage room.

At this time, the solid product transferred to the sterilizing and drying device 70 is charged into an oven and pasteurized and dried by microwave irradiation. By heating the solid product by microwave, the solid product is sterilized and dried.

It is also possible to sterilize and dry the solid product at a high temperature. To this end, a high-temperature heating element made of a metal or a non-metal material is provided, which is heated by supplying electric energy to the inner side of the oven. In this case, the inside of the solid product is heated by the microwave, and the surface of the solid product is heated by the high-temperature heating element, so that the inside and the outside of the solid product as the protein dehydration cake are simultaneously heated, .

Here, the sterilization drying time can be appropriately selected depending on the water content of the protein dehydrated cake, and it is preferable to dry treat the product to less than 10% water content.

3 is a schematic view of a sterilizing and drying apparatus according to an embodiment of the present invention in which a solid product 65 charged into an oven 71 is pasteurized and dried by a microwave irradiation device 72 and a high temperature heating element 73 For example.
