Description

{A method for producing an additive capable of improving the function of a feed for aquaculture}

The present invention relates to a method for producing an additive capable of improving the function of a compound feed for aquaculture.

In the field of fish farming, the national policy to limit the use of raw feed that causes marine pollution and depletion of fish and fishery and promote the conversion to E.P (Extrusion Pellet) has been continuously implemented.

However, the reason why it is difficult to convert all of the compounded feeds that are being promoted by policy is that the blended feeds made of processed protein form do not sufficiently follow the growth rate compared to the raw feeds, and thus the economic efficiency of the business is poor.

In order to overcome this problem, fishermen using aquaculture feeds supplement various parts by adding various additives to the aquaculture farm site. In the process of supplementing additives in such a field, only a simple protein or some amino acids are supplied, but this alone has a problem that does not reach the effect of raw feed.

In addition, there is a problem in that it is difficult to apply to the aquaculture site because the blended feed composed of only protein sources (fish meal or soybean meal) processed by heat in the form of powder has limitations compared to raw feed.

In addition, currently commercially available blended feed is produced and distributed in large quantities due to the characteristics of the manufacturing process and the productivity and profitability of manufacturers, but in the field of farming, custom-made blended feed is desired to be applied to various aquaculture environments.

Prior to the description, advantages and features of the present invention and methods for achieving them will be made clear by referring to embodiments described below in detail together with the accompanying drawings. In addition, the terms used in this specification are for describing the embodiments and are not intended to limit the present invention. Among these terms, the singular form also includes the plural form unless specifically stated in the phrase, and the word indicating the direction in the description is to help understanding the contents of the invention and may be changed according to the point of view. In addition, detailed descriptions of related well-known technologies that may unnecessarily obscure the subject matter of the present invention are omitted.

Referring to Figures 1 to 3 with reference to the additives prepared through a preferred embodiment of a method for producing an additive that can improve the function of the aquatic feed for aquaculture products according to the present invention will be described in detail as follows.

The production method of additives that can improve the function of aquatic feed for aquaculture products includes a main raw material preparation process, a stirring process, a drying process, a crushing process and an addition process.

The main raw material preparation process is a process of preparing each of krill peptide (Peptide) in the form of a paste and soybean peptide in the form of a powder, which are the main raw materials of the additive according to the present invention.

The process of preparing each of the paste-type krill peptides in the main raw material preparation process is a krill preparation step, a wet pulverization step, an extraction decomposition step, a separation and degassing step, a pH control step, an inactivation step, a centrifugation step, a filtering step, a concentration step, and a sterilization step. This includes steps.

The krill preparation step is a step in which frozen krill is secured and then frozen and stored at -18 ° C or lower.

In addition, the wet grinding step is a step of washing the stored krill with purified water and then grinding it with a wet grinding machine.

Along with this, the extraction and decomposition step is a step of transferring the crushed krill to a predetermined closed tank and then adding an enzyme to decompose it for a certain period of time under a certain temperature condition to liquefy to separate into proteins, fats and shells.

In addition, the separation and degassing step is a step of separating the shell by passing the liquefied krill through a decantar centrifuge.

Next, the pH adjusting step is a step of improving the stability by controlling the hydrogen ion concentration of the liquidified krill with the shell separated after the separation and degassing step.

Subsequently, the inactivation step is a step of inactivating the enzyme added in the extraction and decomposition step to prevent deterioration of the liquefied krill.

And the centrifugation step is a step of centrifuging the liquefied krill that has undergone the deactivation step to separate the oil and the liquid krill peptide.

In addition, the filtering step is a step of removing foreign substances by filtering the liquid krill petite separated from the oil.

Next, the concentration step is a step of vacuum-concentrating the moisture content of the liquid krill peptide from which the foreign matter has been removed to 60% or less to form a paste.

Subsequently, the sterilization step is a step of pasteurizing krill peptide in paste form.

The preparation process of preparing the soybean peptide in powder form constituting the main raw material together with the above-described krill peptide comprises a soybean meal preparation step, an anaerobic fermentation step, a vacuum drying step, a low temperature cold air drying step and a grinding step.

The soybean meal preparation step is a step to secure the prepared soybean meal and Lactobacillus reuteri or Lactobacillus acidophilus.

And the anaerobic fermentation step is a step of forming a soybean peptide by peptide-separating the protein in the soybean meal through the anaerobic fermentation process of the soybean meal and seed germs.

Along with this, the vacuum drying step is a step of drying the soybean peptide in a vacuum to prevent damage and loss.

For the vacuum drying step, the anaerobic fermentation step hydrolyzes 30 to 40 parts by weight of water based on 100 parts by weight of soybean meal and seed germ added during fermentation. Due to this, protein modification and oxidation process due to heat may occur during general drying. In the case of vacuum drying, vaporization occurs at around 30 ° C depending on the degree of vacuum and evaporation of moisture prevents protein damage as well as loss of beneficial fermentation products (such as proteolytic enzymes and vitamin B12) and is oxidized by drying in a vacuum. Can prevent the process.

Next, the low-temperature and cold-air drying step is a step of cold-drying the soybean peptide dried in a vacuum to improve preservation.

The vacuum drying step, which is a preceding step, aims to maximize the preservation of soybean peptide by drying the fermented soybean peptide by 10 to 15%, and then further drying 5 to 10% through cold air drying.

Subsequently, the pulverizing step is a step of pulverizing the cold-air dried soybean peptide, and the soybean peptide is relatively easily adsorbed and decomposed in water, but it is further facilitated that the soybean peptide in powder form is completely dissolved in water by performing a pulverization process. By doing so, it is possible to prevent the loss of soybean peptide by completely adsorbing it to the blended feed.

After the main raw material preparation process, a stirring process is performed.

The stirring process is a process of stirring and mixing the main raw material paste type krill peptide and powdery soybean peptide, and includes a raw material injection step, a mixing step, a twin-screw screw mixing step, and an instantaneous low pressure discharge step.

In the raw material injection step, the raw material input ratio was 35 to 65% by weight of soybean peptide in powder form and 35 to 65% by weight in krill peptide in paste form, soybean peptide was quantitatively introduced into the stirrer using a screw conveyor, and the krill peptide was liquid. Therefore, it is a process to quantitatively inject the stirrer using pumping means such as a gear pump.

And the mixing step is a step of stirring the input material by supplying steam while maintaining the temperature inside the stirrer within the range of 35 ° C to 45 ° C.

In addition, the twin screw mixing step is a step performed in a total of three steps in each of three sets of a pair of screws driven by each axis as a twin axis, the first twin screw mixing step, the second twin screw mixing step and the third twin screw mixing step By comprising, it will induce sufficient adsorption between the soybean peptide in the powder form and the krill peptide in the paste form.

The first twin screw mixing step is a step of agitating the agitated raw material through the above-described mixing step with a first twin screw that is rotated (clockwise), and the second twin screw mixing step is a step of mixing the raw material stirred in the first twin screw. It is a step of stirring with a second twin-screw screw that is reversed (counterclockwise), and a third twin-screw screw mixing step is a step of stirring the raw material stirred in the second twin-screw screw with a third twin-screw that is rotated forward.

Here, the first twin screw, the second twin screw, and the third twin screw are horizontally or vertically arranged, and means for transferring the stirred raw material may be installed between each twin screw.

In the mixing step of the twin screw, in the first step, in the second step, in the second step, in the third step, the twin screw is driven in the forward direction to induce adsorption between the main raw materials. In particular, in the second step, the main raw material is stirred in the reverse direction. It is possible to improve the adsorption efficiency between the main raw materials.

In addition, in the twin screw mixing step, the temperature at the time of agitation in each step is maintained at 50 ° C. or less to prevent heat loss of raw materials due to the temperature rise due to friction in each twin screw. This is possible by installing a double jacket on each twin screw to circulate the cooling water to prevent the temperature rise of the twin screw by friction heat.

In addition, it is desirable to improve the adsorption between the main raw materials by making the total stirring time of the twin screw mixing step within a range of 30 seconds to 90 seconds.

In addition, the instantaneous low pressure discharge step discharges the main raw material that is agitated in the third twin screw and discharged to the discharge port in the form of pellets having a diameter of 1.5 mm to 5 mm to facilitate the subsequent process. This is made possible by installing a die formed with holes between 1.5 mm and 5 mm in diameter at the discharge port of the third twin-screw screw to collect the stirred main raw material into the inner space of the die and then discharge it at high pressure through the hole.

After the stirring process, a drying process is performed.

In the drying process, the main raw material discharged in the form of pellets is transferred to a low-temperature conveyor dryer capable of drying in a temperature range of about 50 ° C. or so to prevent the destruction of nutrients caused by heat generated during stirring.

Next, a crushing process and an addition process are performed.

The crushing process is a process of pulverizing and pulverizing the dried main raw material in the form of pellets having a diameter of 1.5 mm to 5 mm, and the adding process is based on 100 parts by weight of the pulverized main raw material, 1 to 5 parts by weight of nucleic acid (nucleotide) and stevia It is a process of adding and mixing 3 to 8 parts by weight.

The reason for the addition of nucleic acid (nucleotide) and stevia is as follows.

Nucleic acids (nucleotides) are non-protein parts of nuclear proteins and are essential components in all living cells.

There are two types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA is a schematic of a living body, and RNA synthesizes necessary proteins by collecting amino acids, which are components of the protein, based on the schematic of DNA. Creatures cannot live without these nucleic acids.

In addition, nucleic acids are effective in promoting metabolism, antioxidant, peripheral blood vessel expansion, liver function improvement, oxygen utilization efficiency, and activation of the vitamin B group. The liver, called the chemical plant of the body, makes substances necessary for maintaining the living body. At this time, when nucleic acid is ingested, the burden of dinobo synthesis in the liver is reduced, thereby improving liver function.

As a result, the nucleic acid plays an important role in the development and initial growth of the digestive organs of aquatic aquatic products, and contributes to the improvement of immune function. In particular, in red snapper, the growth rate can be improved by more than 30% and the survival rate can be improved by more than 10%. There will be.

At the same time, stevia produces a complex effect of potassium, carbonate, and immune vitamins of polyphenols, thereby blocking the activity of "malignant free radicals" that occur in bacteria, etc., thereby enhancing the immunity of individuals and maintaining a healthy state. .

The additive prepared according to the embodiment of the present invention has the following characteristics.

The final protein content of the additive is between 55-65%, the protein form is a peptide and is soluble in water in powder form.

In addition, among the amino acid composition in krill peptide, the content of glutamic acid is extremely high and the content of free amino acid is excellent, so it is not only soluble in water, but also made of powder after concentration due to specific amino acid (glutamic acid). Later, since it has stability in water, there is no loss of raw materials, and water pollution can be prevented.

In addition, in the case of the existing blended feed, the protein content is maintained at a level of 40-50%. Due to the characteristics of the blended feed manufacturing process, it is difficult to manufacture products with more than 55%, and in order to make the form of the blended feed (Extrusion Pellet), a certain amount of flour or starch is required. The product must be formulated in a ratio (15-25%) to produce the product, and even if the rest of the raw materials are formulated entirely with fishmeal (65% protein), it is difficult to make a product with a protein level of 55% or higher. However, in the present invention, when dissolved in water and adsorbed on feed, 10-25% based on the dissolved solution and 5% -15% based on the additive according to the present invention can be added to increase the protein content of the existing blended feed product by 2.7-10%. There is an advantage that can increase the degree. In addition, the 45% protein content of the blended feed is a 55% protein content product, and the 55% compounded feed has the advantage of increasing the protein content to 65%.

In addition, in the case of existing additives (adjuvant), each function, such as amino acids, vitamins, mineral feeds, attractants, immune enhancers, and digestive agents, is separated and independent, so there is the inconvenience and content of mixing various ingredients in fish farms. Some parts are difficult to control. However, according to the present invention, protein amino acid supply (peptide), inducing effect (nucleic acid, glutamic acid in krill peptide), increase in feeding (stevia), increase in physiological activity and immunity (nucleic acid) and digestive function (soybean peptide), etc. are collectively combined. Therefore, the present invention has the advantage of being able to implement the functions of most of the existing additives (surcharge).
