Abstract

PURPOSE: A method for preparing soft solid granule feed is provided, to improve the rate of intestinal absorption of fish. CONSTITUTION: The soft solid granule feed is prepared by mixing 50 kg of fish flour with the moisture content of 10-20 %, 20 kg of wheat flour, 25 kg of corn flour, and 5 kg of additives such as kelp flour, vitamins, minerals, choline chloride, sodium polyacrylate and a soy bean; adding a mixture which comprises 15-20 kg of the internal organs of a squid with the moisture content of 10-40 %, 2-5 kg of fish oil and a small quantity of glycerin to the mixture; mixing it to be gelatinized; and pasteurizing it by using the friction heat of a molder and forming the pelleted feed. The feed contains about 20% of water and about 15% of fats.

Description

Manufacturing method for a feeding food having a property of solid and soft particles}

The present invention relates to a method for producing a soft solid compound feed, and more specifically, to produce a soft solid compound feed that can maintain a fat content of about 15% while maintaining a water content of 20% or more softness that can improve the digestion absorption rate of fish It is to provide a solid blended feed.

In recent years, fish feed has been manufactured by mixing fish waste from the fish processing plant with the purchase of fish for feed when needed due to partial nutritional deficiency, deterioration, and storage problems. As the price fluctuates by the amount of catches and the timing, the frequency of use is gradually increasing due to the convenience of the blended feed, which is a human dye.

According to this trend, various compound feeds have been manufactured and supplied to seawater aquaculture farmers, but due to manufacturing constraints, dry pellets, or DP, were manufactured as hard and dry feeds.

This is convenient for storage, but low-temperature fish (20 ℃ or less), when fed DP, which is a low-moisture solid grain feed, shows low digestibility and shows partial nutrient deficiency. Even with the problems of causing a great deal of damage to property due to the death of aquaculture fishes, the rise of cost of production has led to a serious crisis in the fisheries industry that gives up aquaculture.

The present invention has been researched and developed for many years to solve the problems of the DP feed as described above, wheat flour and corn starch and other additives (fish kelp, synthetic vitamins, synthetic minerals, choline chloride) in fish meal with a water content of about 10-20% , Polyacrylic acid soda, soybean) mixed with squid with water content of about 10-40% and glycerin fish oil, and sterilized by frictional heat during molding process. SDP (Soft Dry Pellet) with water content of around 20% The present invention has been completed in view of the technical problem of the present invention to provide a method for preparing a soft solid particle feed to increase the growth rate of the fish by providing a feed suitable for low-temperature fish by preparing a feed.

1 is a block diagram showing a manufacturing process of the present invention

The present invention is to provide a soft solid compound feed that can improve the digestive absorption rate of fish by preparing a soft solid compound feed that can be maintained at about 15% crude fat while maintaining a water content of 20% or more. It will be described in detail.

<Production method>

1. Mixing Low Moisture Raw Materials

50kg fish meal with water content of 10 ~ 20%, 20kg wheat starch, 25kg corn starch and 5kg additives (Tashima flour, total vitamin, synthetic mineral, choline chloride, soda polyacrylic acid, soybean) do.

2. Mix of juicy raw materials

15 to 20 kg of squid with water content of about 10 to 40% is added and mixed with 2 to 5 kg of fish oil and a small amount of glycerin.

3. Mixing

The mixture is added to the mixture with a small amount of moisture to prepare a gelatinized semi-finished product. At this time, the water content of the mixture is maintained about 20% and also contains about 15% fat.

4. Molding

As described above, the mixture is mixed and mixed, and then put into a molding machine to sterilize harmful bacteria as frictional heat of the molding mold and at the same time make pelletized feed.

5. Screening

By moving the feed of the present invention made by the above method to a transfer device or the like to remove the substandard or impurities so that the feed can be advanced.

6. Weighing and Packing

The finished feed that is subjected to the above process is packaged in small units of a predetermined weight. At this time, it may be packed in a zone or a sack, but it is better to use a plastic case for convenient movement and storage.

7. Storage

As described above, the SDP feed of the present invention prepared through all the processes is preferably stored in a refrigerating chamber that can maintain a temperature of 4 ~ 8 ℃.

In the above manufacturing process, avoiding partial control by the rough nutrient demand rate and setting specific nutrient demand rate for each fish species to expand and classify it for fry, larvae, cultivation and parent fish to manufacture and supply ductile and particle size in granular form. It is natural.

SDP feed of the present invention prepared as described above can be mainly used as a food for fish growing at low temperature, when the feed of the present invention is used, the moisture content is 20% or more, the water content is high, and it is deformed even at a slight pressure. It has elasticity and contains about 15% of crude fat in nutrients, and by using raw foods such as fish meal or squid intestine, it is possible to feed water (nutrient hexagonal water with hexagonal angle of 105 °) or nutrients contained in raw foods as it is so that digestibility is low. It will be able to supply high calorie feed and accelerate the growth rate of fish.

<Example>

As a result of feeding the SDP feed of the present invention to the dome, defense and horse mackerel, as shown in Table 1, each fish species showed digestion absorption rate of 80% or more.

Kinds Digestion Absorption Rate (%) DEKcal / g protein Fat carbohydrate Calories (calorie) Dome 94 93 93 93 4.9 defense 86 89 65 82 4.3 pompano 90 92 92 89 4.7

On the other hand, it can be seen that the growth rate is significantly improved as shown in Table 2.

Breeding start date 6/1 6/30 Average weight (㎏) 21 114 End date 10/30 9/29 Average weight (㎏) 1,310 811 Misu 8,570 14,641 Total weight (kg) 9,193 8,667 Salary (kg) 8,660 7,880 Weight gain factor 0.94 0.90 Weight gain correction factor 0.78 0.77

As described above, the present invention can reduce the manufacturing cost of the feed by manufacturing the SDP feed by using the fish meal and the by-products discharged from the processing plant, while maintaining 20% fat and 15% moisture as mentioned above. When fed to fish growing at low temperatures, it is possible to minimize the mortality caused by diseases by improving digestive absorption rate and to obtain benefits that can improve the growth rate and nutritional status. It is an excellent invention.
