Description

The feed raw material and the feed manufacturing method using the microorganism and liquid pickled sludgemanufacturing methods of feed using salted seafood of sludge

The present method relates to a feed raw material and a feed manufacturing method using microorganisms and fish sauce sludge, and more specifically, the sludge, which is discarded after the production of fish sauce, is subjected to various processes to sterilize spoilage bacteria and harmful bacteria, It relates to a feed manufacturing method using microorganisms and fish sauce sludge that can provide beneficial nutrients to livestock and help growth and development by manufacturing and supplying feed of fat, protein, and organic matter after removing toxicity.

In general, there are various forms of using seafood.

One of them is salted or fermented to facilitate long-term storage and is used as a raw material for seasoning when making kimchi or boiling soup.

Most of these fermented foods refer to adding a large amount of salt to aquatic products and fermenting and aging the seafood by the action of proteolytic enzymes.

On the other hand, fish sauce, one of fermented seafood, refers to a liquid substance separated into juice by fermenting salted fish for a longer period of time.

The above-mentioned fish sauce has a umami taste, a strong taste, and a unique flavor of fish produced as a result of aging by enzyme action, and is mainly used as a seasoning food serving as an appetite enhancer.

In fact, it is used as a seasoning, which is an auxiliary raw material for seaweed soup, pumpkin pickle, and kimchi dipping, and various types of salted fish and kimchi using them are active depending on the region.

Conventionally manufactured fish sauce contains water, salt, and small amounts of amino acids, nitrogen and calcium. As an example of a typical fish sauce, anchovy fish sauce contains various amino acids such as glutamic acid, aspartic acid, glycine, alanine, and lysine and nucleic acids. Since it contains a large amount of rice-polishing ingredients, it has been widely used for seasonings such as kimchi and stir-fried foods since ancient times.

In the past, most of these fish sauces were self-sufficient and consumed at home, but recently, large-scale factories are producing fish sauces with improved sanitary and storage properties, and the demand for them is gradually increasing.

As described above, as the demand for fish sauce increases, there is also a problem with the treatment of sludge left after making fish sauce.

The above-mentioned fish sauce sludge should be disposed of as food waste, but since the fish sauce sludge contains a high concentration of salt and a large amount is discharged, it remains another task to solve the fish sauce sludge thus discharged.

Accordingly, as a proposal, Korean Patent Registration No. 10-1195590, a method for producing a feed containing fish sauce by-products has been proposed.

However, the method for producing a feed containing fish sauce by-products requires various kinds of materials, so it is difficult to supply and supply the materials smoothly, and accordingly, there is a problem in that continuity in terms of productivity is deteriorated.

In addition, there was a problem in that the purchase cost for purchasing various types of materials and accordingly the manufacturing cost and the selling price increased.

desalination step

The fish sauce is made by mixing the selected fish and salt in an appropriate ratio, and the fish and salt in the sealed container are aged for several years.

That is, the fish residue is deposited to form sludge, and only the clear liquid is separated and used as a fish sauce.

As described above, the fish sauce sludge generated during the process of immersing the fish sauce contains a lot of nutrients and has a water content of 90% or more. It contains about 20-40% salt.

100 parts by weight of the above-mentioned fish sauce sludge is mixed with 200 parts by weight or more of water, and the process of stirring, washing, and draining is repeated several times to wash and first remove salt.

Fish sauce sludge separation step

The salt removal step is performed as described above, and in a state where water and fish sauce sludge are mixed, the fish sauce sludge is separated except for water and solids deposited in the water.

The fish sauce sludge separated and collected as described above is placed on a tray until the moisture content is maintained in the range of 50% to 80%.

Fish sauce sludge drying stage

After the fish sauce sludge separation step is completed as described above, the fish sauce sludge is put into a drying device and dried.

Preferably, the drying conditions in the fish sauce sludge drying step include drying so that the water content in the fish sauce sludge is maintained at 13% to 18% and salinity of 0.5% to 3.0%. During the process, harmful bacteria contained in the sludge are sterilized.

Meanwhile, the drying conditions required for the above-mentioned fish sauce sludge, that is, 13% to 18% moisture content and 0.5% to 3.0% salinity, are the conditions for the first embodiment to be used as an auxiliary raw material for feed. In the conditions in the third embodiment, it is not necessary to satisfy the above conditions.

Dry sludge grinding step

As described above, after completing the drying step of the fish sauce sludge, the dried sludge is pulverized into pellets or powder and shipped as a product.

The product shipped by the above process may be mixed with general feed or used as an auxiliary feed mixed with a separate finished feed.

That is, since the product in the form of pellets or powder finished by the above process contains many nutrients, it can be used as an auxiliary feed for mixing and supplying an appropriate amount to the feed of livestock in need of the nutrients.

Feed raw material mixing stage

50 to 150 parts by weight of one or a mixture of two or more selected from the group consisting of rice bran, wheat bran, soybean meal, and zeolite (or bentonite) with respect to 100 parts by weight of the dried sludge after completing the pulverizing step of the dried sludge .

The rice bran has a high energy content, contains a lot of carbohydrates, fats, proteins, and vitamins B1 and E, and has a function of maintaining the appropriateness of the salinity contained in the fish sauce sludge of 1% to 3%.

The wheat blood is rich in nutrients as the residue left by grinding wheat and sieving.

The soybean meal is a by-product remaining after milking soybean oil, has excellent palatability, and serves as a standard for comparing the price or quality of other protein feeds as a representative raw material of vegetable protein sources.

In the case of dehulled soybean meal, the crude protein content is 48%, and soybean meal with a crude protein content of 44% to 46% is produced depending on the amount of soybean hull added. The crude fiber content varies depending on the amount of soybean hull added. The crude fiber content of dehulled soybean meal is about 3.5% and 44% soybean meal is about 6%.

The soybean meal is suitable for all livestock, has good palatability, contains methionine as a restricted amino acid, and has a more uniform protein content and amino acid composition than other vegetable protein raw materials.

It is preferable to mix 0.5 parts by weight to 2 parts by weight of the zeolite or the bentonite.

The zeolite has an ion exchange ability and is used as a water purifying agent or a metal ion scavenger in aqueous solution, and the bentonite contains silicon dioxide as a main component and mostly contains baking soda and has a function of fundamentally removing odors.

Bacterial Fermentation Steps

After completing the feed raw material mixing step, 3 to 5 parts by weight of the Bacillus strain are mixed with 100 parts by weight of the feed raw material mixture, put into a stirrer, an airtight container, and fermented with stirring at a temperature of 20° C. to 40° C. for 4 to 12 hours. make it

The reason for stirring and fermentation in the airtight container as described above is to increase the bacterial fertility of the Bacillus strain, which is a beneficial bacteria, at a temperature of 20°C to 40°C, while removing harmful bacteria and buffet bacteria contained in the fish sauce sludge.

In addition, it is because it has a deodorizing effect that alleviates the inherent odor emitted from the fish sauce sludge.

The above-mentioned Bacillus strain (Bacillus subtilus) accelerates fermentation and decomposition, so it is used as a deodorant and as a purifier of filth or polluted water, and induces a very rapid decomposition in feed distribution of organisms and inorganic matter.

Microbial culture step

After completing the bacterial fermentation step, 1 to 3 parts by weight of the microbial culture is mixed with the culture medium for 100 parts by weight of the feed raw material mixture and added.

The microorganism culture strain is a microorganism culture by mixing any one of Joy Lifes bacteria, Aspergillus bacteria, or a mutant strain mixed with Joy Life bacteria and Aspergillus bacteria with a microbial culture to maintain a temperature condition of 30 ° C. to 45 ° C. incubate

Beneficial bacteria are activated and harmful bacteria are sterilized while fermenting the fish sauce sludge mixed with Joy Lifes bacteria and Aspergillus bacteria at a temperature of 30° C. to 45° C. for 18 hours and 36 hours.

The reason for adding the Joy Lifes bacteria and Aspergillus bacteria is to supply nutrients to livestock according to deodorization and activation of microorganisms prior to shipment as a product and to prevent an unpleasant odor as livestock feed.

Preferably, beneficial microorganisms, that is, molds, are activated by supplying an appropriate amount of moisture through a spray device or a water supply device during the culturing of the microorganisms.

When the microbial culture step is completed as described above, the feed mixtures are in a powder or pellet form while going through the above-mentioned dry sludge pulverization step, so they can be commercialized immediately, but may be subjected to a separate additional pulverization process again.

Of course, the size or shape of the dried fish sauce sludge pulverized as described above is not limited to the size or shape of the particles, such as powder or pellets, and the pulverized shape or size can be adjusted according to the characteristics of the animals to be fed. .

On the other hand, in the second embodiment as described above, the feed may be manufactured through a sterilization drying step and a second grinding step to be described later.

Sterilization drying step

After completing the microorganism culturing step, the temperature condition of 60 ° C to 80 ° C is maintained with respect to 100 parts by weight of the feed mixture, and the conditions of moisture content of 13% to 18% and salinity of 0.5% to 3.0% are maintained and sterilized and dried.

After completing the microorganism culturing step, 100 parts by weight of the dried fish sauce sludge is dried at a temperature of 60°C to 80°C for 4 to 8 hours, and dried to maintain the conditions of 13% to 18% moisture content and 0.5% to 3.0% salinity, Odors and harmful bacteria remaining in the fish sauce sludge are finally removed.

The dryer used at this time may use a dryer widely used in rural areas in general.

The sterilization drying is dried in a state of being stacked on trays arranged at regular intervals in consideration of smooth ventilation in a drying room having a structure in which normal warm air is circulated.

And after the above sterilization and drying step is completed, the characteristic odor generated in the fish sauce sludge disappears and becomes odorless.

second grinding step

After completing the sterilization and drying step, the sterilized and dried feed mixture is pulverized into powder or pellet form and commercialized.

Of course, the size or shape of the dried fish sauce sludge pulverized as described above is not limited to the size or shape of the particles, such as powder or pellets, and the pulverized shape or size can be adjusted according to the characteristics of the animals to be fed. .

The feed additive completed by the above manufacturing process and mixture contains 25% or more of crude protein and 15% or more of crude fat, so it can be mixed with feed suitable for the characteristics of livestock and supplied as a finished feed.

In addition, the feed completed by the manufacturing process as described above may be used as an additive for supplying separate nutrients to livestock by mixing an appropriate amount with the generally supplied livestock feed.

On the other hand, according to the feed raw material and feed manufacturing method using the microorganism and fish sauce sludge completed by the present invention, the sludge, which is the fish residue, which is discarded after manufacturing the fish sauce, goes through various processes such as sterilization and fermentation, and is used as feed or feed additive, so it is not discarded. Recycles aquatic product residues, so it is possible to supply feed to livestock houses at low cost by manufacturing feed or feed additives at low cost.
