Description

TECHNICAL FIELD The present invention relates to a fermented feed, a fermented feed, and a fermented food suitable for the fermented feed,

The present invention relates to a method for producing feeds fed to aquaculture fish, and more particularly to a method for producing a fermented feed using dead fish and a residual product of fisheries, a fermented feed produced thereby and a fermenter .

In the course of fish culture, fishes (hereinafter referred to as "dead fishes") are caused by red tide inflow, fish diseases, lack of oxygen and other causes. On the other hand, coastal fisheries and fisheries processing companies also produce fishery by-products.

At present, about 30 ~ 40% of fish species are lost in the process of fish culture, and this is treated as industrial waste, so the disposal of dead fish is emerging as an urgent issue.

On the other hand, the price of aquaculture feed is increasing day by day, and supply quantity is also insufficient.

Therefore, environmental pollution caused by these wastes has been a problem. Considering the nutritional value of these dead fishes and fishery by-products, it has been demanded to use them as recycled rather than simply disposing of them.

In response to these demands, there has been a method of using dead fish and aquatic by-products as raw material.

However, fish, such as this raw material, has a high protease and high content of unsaturated fatty acid, which is high in corruption and oxidation progress, even though hair, bark, and bone contain a large amount of useful components such as proteins and minerals. It was very limited.

As an example of a conventional technique for overcoming this problem, Korean Patent Laid-Open Publication No. 2002-0003776 (published on Jan. 15, 2002) discloses a method in which fish is crushed to a predetermined size, A method of making a feed is disclosed.

On the other hand, in Korean Patent Laid-Open Publication No. 1999-0046663 (published on May 7, 1999), the fish by-product is heated and decomposed at high temperature to be adsorbed on the grains and fermented using main anchovy and yeast, Such that the resulting digestive enzymes and metabolic products are contained in the feed.

However, these conventional technologies have problems such as requiring a huge production facility and thus excessive maintenance cost, or the by-products other than juice still remain.

On the other hand, the commercially available high-quality fish meal is known to have a protein content of about 60 to 70%, and general fish meal feeds that mix high quality fish meal with other ingredients usually have a low protein content of less than 30%. However, high quality fish meal is not widely used because it has a high price of about 70,000 won per bag of 20kg package.

Therefore, farmers are using the low - quality fish meal as a feed for their food.

Accordingly, the development and dissemination of high-quality feeds having high nutrients at low prices are urgently required.

It is an object of the present invention to provide a fermented feed manufacturing method using dead fishes and fish by-products.

Another object of the present invention is to provide a fermented feed manufacturing method using dead fishes and a by-product of fishes, which enables fast fermentation to be performed by putting an aerobic fermentation strain and an anaerobic fermentation strain together.

Another object of the present invention is to provide a fermented feed manufacturing method using dead fishes and a by-product of fishes which can be sterilized together with fermentation by fermenting at a high temperature.

It is still another object of the present invention to provide a fermented feed using dead fish and a fish by-product.

The present invention is characterized in that an aerobic fermentation strain and an anaerobic fermentation strain are uniformly mixed into pulverized fishes having a moisture content, and fermented while appropriately blowing air while stirring with a stirrer.

As a result, the portion of the surface of the fermentation object mixed with the crushed fishes and the moisture control agent mixed with the stirrer is subjected to aerobic fermentation, and the portion of the air inside the fermentation is anaerobically fermented and the fermentation progresses rapidly.

1 is a process diagram showing a fermented feed manufacturing method according to the present invention.

Referring to FIG. 1, the fermented feed manufacturing method according to the present invention includes a crushing step (step s102), a water control agent preparation step (step s104), a dough crushing fish and water control agent feeding step (step s106), a disinfection process (s118), stirring and fermentation process (s116), fermentation product production process (s118), temperature and moisture control process (s110), anaerobic and aerobic fermenting microorganism input process (s112) The fermented feed preparing process (s122), the fillet maker feeding process (s124), the fillet type fermented feed producing process (s126), and the fermented feed feeding process (s128).

First, in the crushing process (s102), the dead fish and the fish by-products are crushed to form a thick fillet or a kneaded crushed fish. Dead fish and aquatic by-products may be stored in a frozen state. The dead fish and by-products stored in the frozen state are crushed and crushed by a crusher and a crusher.

In the preparation of the water control agent (s104), a moisture control agent is prepared so that the water content of the crushed fish can be adjusted to about 60%.

Examples of the moisture regulator include dry fermented feed, wheat bran, soybean meal, rice bran powder, seaweed powder, and various inorganic and organic materials in powder form.

In the process of introducing the crushed fish and the water control agent (s106), the prepared crushed fish and the water control agent are put into a fermenter and stirred with a stirrer.

In the process of disinfection of crushed fishes and moisture control agent (s108), the inside of the fermenter is heated at about 100 ° C for about 20 minutes to 60 minutes to completely sterilize various bacteria and wastes that the object can have. Then, wait for a certain time so that the internal temperature of the fermenter is stabilized at about 50 to 60 ° C.

In the process of introducing the crushed fish and the water control agent (s108), the prepared crushed fish and the water control agent are put into a fermenter and stirred with a stirrer.

In the anaerobic and aerobic fermenting microorganism inputting process (s110), the anaerobic liquid fermentation strain and the aerobic liquid fermentation strain are put into a fermenter.

First, an anaerobic strain in a liquid phase is introduced, and stirred until the strain spreads evenly inside the kneaded object. An anaerobic fermentation broth in a liquid state corresponding to 1 to 4%, preferably 1%, of the total weight of each material put into the fermentation tank is evenly supplied. As the anaerobic fermentation strain, medium temperature or high temperature lactic acid bacteria (Lactobacillus bulgaricus and a mixed strain thereof) are used.

Then aerobic strains in a liquid state are added and agitated sufficiently until the strains are evenly distributed inside the kneaded object while stirring.

The aerobic strain is evenly supplied in an amount corresponding to 1 to 4%, preferably 1% of the total weight of each object put into the fermentation tank. As a aerobic strain, a mixed aerobic strain of Bacillus subtilis, which is a thermophilic aerobic strain, is used.

The present invention allows the fermentation to be performed in a short time by culturing and introducing a strain in a liquid phase, which is not a powdery strain.

Typical strains are prepared by lyophilization and lyophilization to a high concentration of powder, and since the strain is in a dormant state, it takes some time to activate. Therefore, in order to reduce the fermentation time in the fermentation process, the culture broth is prepared as a component necessary for the activity and culture of the strain, and a proper amount of the powdery strain is added thereto. It is added to the dough and fermented for quick fermentation. Liquid strains should be stored in disinfected containers for use within the period of validity.

In the process of controlling the stirring speed and air flow rate (s114), the stirring of the stirrer is continuously performed at a low speed of about 10 to 20 rpm while a small amount of air is introduced into the fermenter by the blower.

Since the present invention simultaneously performs aerobic fermentation and anaerobic fermentation, it constantly blows air into the fermentation tank during the fermentation period. The amount of air to be blown may be as much as necessary to carry out aerobic fermentation on the surface of the object. Preferably a minimum amount of air required to proceed aerobic fermentation.

The stirring fermentation process (s116) proceeds for about 20 to 24 hours. If the temperature applied to the fermenter is kept at about 50 ° C from the wall of the fermenter, the temperature of the air inside the fermenter rises up to about 55 ° C due to the action of the fermenter, and when the fermentation is almost completed, ℃. When the fermentation is almost finished (after 20 hours after fermentation), the air supplied to the fermenter is sufficiently turned on so that drying can be performed quickly. Organic materials of the input materials are fermented and decomposed after about 24 hours, resulting in powdery particles.

In the fermented feed preparation process (s118), the water content of the fermented feed is adjusted to about 15%.

The prepared fermented feed is mixed with about 30% of raw material and fish meal, and a fillet type fermented feed is prepared using a fillet producing machine and provided to a fish culture fishery field. (s120 to s128)
