Description

[0001] The present invention relates to a method for manufacturing a fish feed and a method for manufacturing the same,

The present invention relates to a method for producing a feed of fish and a feed prepared thereby, and more particularly, to a method for producing a feed having both floatability and sedimentation as a feed to a fish and a feed prepared thereby.

Recently, the population of marine, freshwater, and aquarium fishes has been greatly increased, and the efficiency and convenience of the feed have been dramatically improved. Accordingly, composite feeds have been developed that are both sedimentary (sedentary) feeds, flotation (floating on water) feed, and some feeds that are settled and some are floated.

If the feed is injured, it is not suitable for fish that like to live in the lower part of the water. The precipitated feed is lost because some of the settled fish is caught in gaps or gaps between the fish and the fish.

As a result, feed efficiency is lowered, leading to economic loss, as well as pollution of the environment and destruction of the environment by threatening fish life.

And, the feed according to the preferred embodiment of the present invention is produced by the fish feed manufacturing method described above.

According to the present invention having such a constitution, the weight of skim milk powder in the feed becomes high at the moment when water is eaten and the skim milk powder is sedimented and the skim milk powder, which completely eats water, gradually dissolves in water and the weight of the feed is gradually lowered.

It is gradually settled and finally floated again to show various feeding responses of several layers and to minimize contamination of breeding water. And, unheated residual diets (feeds floating in water) are easy to recover to prevent contamination of water.

In addition, since the microbes are produced at a low temperature, even after production of microbes insufficient in heat resistance, microbes remain in the products after production, so that the activity of the microbes is not reduced.

Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning in the context of the relevant art and are to be interpreted in an ideal or overly formal sense unless explicitly defined in the present application Do not.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In order to facilitate the understanding of the present invention, the same reference numerals are used for the same constituent elements in the drawings and redundant explanations for the same constituent elements are omitted.

Traditionally, feed has been produced by compressing the feed by applying heat and pressure to the raw material, or applying heat and steam pressure to the feed. Pressurized feed is floatable in water, and feedstock is a sedative feed. The embodiment of the present invention is characterized in that it has both flotation and sedimentation by overcoming this conventional production method.

To this end, the method for producing a fish feed according to an embodiment of the present invention comprises the steps of preparing a raw material including fish meal, egg white, wheat flour, krill, skim milk and gluten, mixing the raw materials into a mixer, Low temperature processing of the formed particles (e.g., sizes of about 0.1 to 0.5 mm) in a fluidized bed granulator dryer to shape the granules, and making the granules to a desired size.

Here, it is preferable that the fish meal is composed of 30% by weight, the whole egg is 21.97% by weight, the flour is 20% by weight, the krill is 20% by weight, the skim milk is 5% by weight and the gluten is 3% by weight. Eggplant has better digestion rate than fish meal and reduces fecal matter. Wheat flour and gluten, when encountered with water, create particles with increased viscosity. Krill is intended to further enhance the color of the skin of the fish, which, incidentally, helps to strengthen fish growth and immunity. The skimmed milk powder has a high specific gravity at the moment of water ingestion, allowing the sedimentation of the feed to take place, and the skimmed milk powder that has completely eaten the water gradually dissolves in the water to lower the weight of the feed.

The raw material may further contain 0.01% by weight of a vitamin mix and 0.01% by weight of vitamin C. The vitamin mix is intended to balance the nutritional balance of the fish, including the lactoferrin ingredient to enhance the immune system. Vitamin C is used as a preservative substitute.

In addition, the mixing step includes spraying a spraying liquid mixed with 70% alcohol and 30% water.

Also, the step of making the granules shape sets the temperature of the fluid bed granulator dryer such that the core temperature of the raw material (i.e., the internal temperature of the particles) is less than a certain temperature (e.g., 50 캜).

And, the step of making the granules to a desired size can be performed by using a binder (for example, CMC, Zanthox, pectin, carrakinan, etc.) to make granules of desired size.

A method of manufacturing a fish feed according to an embodiment of the present invention will be described with reference to FIG.

First, a raw material is prepared (S10). The raw materials may include fish meal (including altemia), egg whites, flour, krill, skim milk powder, gluten and vitamin mix, and vitamin C. Here, the fish meal is 30% by weight, the whole egg is 21.97% by weight, the flour is 20% by weight, the krill is 20% by weight, the skim milk powder is 5% by weight, the gluten is 3% by weight, the vitamin mix is 0.01% 0.01% by weight.

Next, a spraying liquid mixed with 70% of alcohol and 30% of water is prepared (S12).

Then, the raw material is put into a mixer, and the spray liquid is sprayed while spraying (S14). Here, the reason why the spray liquid is sprayed is that the water in the spray liquid can increase the viscosity of wheat flour and gluten to make the raw material particles. The alcohol in the sprayed liquid is evaporated all at a later time, so that small pores are formed in the particles and sterilize the raw materials.

When the spray liquid is sprayed for a predetermined time (for example, several minutes), the raw material is made into very small particles (for example, about 0.1 to 0.5 mm in size) (S16).

Thereafter, the particles formed in the mixer are introduced into a fluidized bed granulator dryer (S18). Here, the reason for using the fluidized bed granulator dryer is that the conventional feed is almost extruded, and nutrient destruction occurs due to high heat, so that the microbial material having low heat resistance is post-processed. However, since the fluidized bed granulator dryer is capable of low-temperature production and the granules are formed and the low-temperature drying can be performed as the respective raw materials are bound to each other in the original state of the raw materials by using the binder in the weightless state. If you are in the same industry, I know the fluidized-bed granulator dryer, so I do not give any specific details about it.

Then, the temperature of the fluidized-bed granulator dryer is set to a low temperature and low-temperature processing is performed (S20). Here, the temperature setting of the fluidized bed granulator dryer is set so that the core temperature of the raw material (i.e., the internal temperature of the particles) does not exceed 50 占 폚. When the low-temperature processing is performed through the fluidized-bed granulator dryer, the particles are aggregated into granules of a predetermined shape.

Then, finally, granules of the desired size are made using a binder dissolved in water (for example, CMC, Zanthox, pectin, carrakinan, etc.). The thus-formed granules of the desired size can be fed (S22). At this time, the compounding ratio of the binder accounts for 0.01 wt% of the total content of the raw materials.

On the other hand, the feeds produced by the above-mentioned method can classify the size of the feed according to the size of the fish using the sieve.

The reason why the feed according to the present invention floats after sedimentation is that the weight of the skimmed milk becomes high at the moment of eating the water and the sediment of the feed is settled, and the skimmed milk powder which completely eats the water gradually dissolves in the water, do.

In the embodiment of the present invention, the floating time after sedimentation is somewhat different depending on the depth of the water tank. As a result of the experiment in a water tank of 48 cm long * 29 cm height * 35 cm height, it took 10 to 15 minutes for settling time, and more than 95% of the feed was lifted after 3 to 30 minutes. And remains at the top of the water tank.

Meanwhile, according to the present invention, it is gradually sedimented and eventually floated again, so that various feeding reactions can be performed in several layers and contamination of the breeding water can be minimized. And non-consumed residual diets (ie feeds floating in water) are easy to recover to prevent water contamination.

In particular, even if microbes lacking heat resistance are produced by low-temperature processing, they are advantageous in that the microbes are alive in the products after production, so that the activity of the microbes is not reduced.

In addition, since the feed prepared by the present invention is not made by compression, it absorbs water immediately when it is put into water.

As described above, an optimal embodiment has been disclosed in the drawings and specification. While specific terms have been employed herein, they are used for the purpose of describing the invention only and are not used to limit the scope of the invention as defined in the claims or the claims. Therefore, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
