Food for improved fish style and the manufacture method

The present invention relates to a feed suitable for marine fish farming and a method of manufacturing the same, and more particularly, to provide a SEP feed having a high water content and close to raw feed to improve digestive absorption and feed efficiency when feeding to marine fish. The present invention relates to the provision of an improved feed that can reduce the number of dead ends.

As is well known, the feed used for marine fish farming is divided into raw feeds that are frozen after being processed and thrown away without being processed separately, and juicy MP (moist pellet) feeds that are mixed with powdered feeds and fed. It can be divided into EP (extension or extruded pellet) feed of a form that is extruded and dried in a certain form.

If you look briefly at the advantages and disadvantages of each type of feed,

MP feed and live feed have a problem that it is very difficult to secure the number of workers in each fishery, although the price or nutritional balance is unstable and the secondary processing requires a lot of labor in the field.

In addition, due to water pollution of the near sea, the government has restricted its use. Marine fish have to take water from the outside at all times due to metabolic physiology (adjustment of osmotic pressure). Most of EP feeds currently distributed have low water content. At this level, there are various problems that cannot be overcome in various fish farming.

This results in the loss of labor, such as by adsorbing and feeding water into the EP feed at the fish farm, and in particular, due to slow digestion absorption, frequent diseases caused by digestive disorders, and slow growth at low water temperatures. have.

Compared with the shortcomings of raw feed and MP feed, EP feed has the advantages of excellent preservation, easy handling, relatively stable price, low environmental pollution, and the use of automatic feeder. In addition, it also has its own disadvantages, the list of such disadvantages, marine fish digest digestion of the feed rate is very slow, and thus growth (especially low water temperature) is lowered, metabolic disorders occur due to lack of water, produced during water adsorption It takes a lot of time.

In addition, these EP feeds had a big difference in quality among manufacturers, and there was a problem that the feed rate decomposition rate was slow.

The present invention devised in view of the above problems is to provide an EP feed that is close to a live feed, that is, a soft expension pellet (SEP) feed, and does not mean simply to artificially increase the moisture to soften, but the form of water that the raw feed has In other words, by combining the form of water bound to the cells with EP feed, it is to provide a soft feed of a form close to raw feed rather than merely to increase the moisture content, as part of the development of high-efficiency blended feed at the level of raw feed, growth and stability and By actively supplying SEP feeds to the market to satisfy the competitiveness of fish farms, it is intended to be a practical help for aquaculture fishermen in aquaculture.

The present invention is to provide a SEP feed that is similar to the general EP feed but with a large difference from the existing EP feed, the largest in the SEP feed manufacturing process and EP manufacturing process to be provided in the present invention The difference is that the method of supplying moisture provides intracellular protein and water present in liquid form. Specifically, SP (SQUID PASTE) is supplied before molding using an extruder, which makes the feed soft by simple moisture. It is completely different from the loss, and by supplying the raw material in the form of moisture, it is possible to expect the digestibility close to the raw feed, the growth is characterized by showing a near-growth growth rate.

According to the present invention as described above, the SEP feed having the advantages of raw feed and blended feed has a higher moisture content than the conventional EP feed due to the use of expensive protein sources in liquid form, and the manufacturing process and the produced product are also the same as the EP feed. Therefore, the stability of the product will be secured regardless of environmental pollution and resource depletion, which are pointed out as the disadvantages of existing raw feed.

In addition, as the effect of the direct addition of SP, SP has a very high viscosity (more than 1000000 cps), so it is difficult to transport and supply it as it is, but it is necessary to mix and feed with additives to feed starch (not required for actual fish growth). Can be used to maximize the growth of fish and minimize the loss of nutrition during powdering.

Hereinafter, a detailed embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a process flowchart showing the manufacturing process according to the present invention in order.

Look at the method of manufacturing the feed according to the present invention.

Raw material preparation

Prepare the basic materials needed for manufacturing by grinding and selecting to the required size. The basic ingredients of common feeds are fish meal, soybean meal, wheat flour and corn flour.

Raw material blend

One or two or more prepared grinding materials are selected and blended in an arbitrary ratio, and when a small amount of raw materials for taste, aroma or color are needed, these small raw materials are mixed again and prepared. If necessary, it can be stored in a reservoir and transferred to the next process.

S.P mixture preparation

S.P (squid paste) is prepared by mixing fish oil within the range of 30% to 60% by weight.

A temperature of 40 to 50 ° C. may be added before such mixing or before mixing with the basic feed material.

For reference, the SP (squid paste)
SP is generally used for the utilization of nutrients (amino acids and fatty acids) in squid guts during the process of making fish farms. In the process of existing EP feeds, the squid guts are concentrated at high pressure with steam and are primarily paste (porridge). Form) It is adsorbed on thin film such as soybean meal or soy milk meal, and then mixed and processed to make powder form, which is also called juice adsorption feed.

By the way, the SP has a very high viscosity of 1,000,000 cps or more, so that it was difficult to transfer or supply by machine.
However, the present invention has maximized the raw material cost reduction and utilization rate by developing a process system capable of supplying the paste itself and quantitatively supplying itself, and also maximizing physical properties when used by itself.

Steam Cooking

After mixing the basic raw materials mixed in the conditioner, while mixing and cooking at 40 to 50 ℃ temperature using steam. In this process, the prepared S.P mixture is added while cooking while mixing at the same time.

The amount of the S.P mixture is added in the range of 5% to 15% by weight of the total weight of the S.P mixture added to the basic raw material, and the ratio is added or subtracted within the above range in consideration of various conditions such as the type and temperature of the fish.

Molding process

The mixed material is molded by extrusion (extruding) to form a uniform pellet feed.

Dry and Cooling

The finished feed is dried and cooled, excluding artificial drying which prevents excessive evaporation of moisture.

Finishing process

After the selection, weighing and packaging, the manufacturing is completed.

The feed of the present invention prepared by such a process is a state in which the SP is mixed in a certain ratio, including the intracellular protein and water present in the liquid form in its own components to reach a water content of 20% to 30%, 1,000,000 cps SEP feed in the form of a live feed having the above viscosity is provided.

Feeding the feed according to the present invention to the fish and the results of analyzing the results are as follows.

As can be seen in Table 1

 division  SEP (original invention)  EP  Raw feed  Total feed  737  632  2,105  Total gain  540  463  428  Total death attempt  286  465  715  Feed efficiency  73.27  73.33  20.31

* Target fish species: Black sea bream

* Test period: April 2007 ~ October 2007

Although the feed volume was reduced compared to other feeds, the increase in weight was improved. As shown in Table 2, the number of dead animals was significantly lower than that of other feeds, and the feed efficiency was the highest. It was revealed.

Individual average weights were best in the control group fed with the live feed, with the second lowest SEP and the lowest EP.

Therefore, SEP feed according to the present invention was the most competitive considering the total weight and feed efficiency and mortality.
