Description

{The processing method for a recycling frozen wet feed to the shoals of young fish,}

The processing method of the present invention has been used for a long time, but the processing method is simple and almost unprocessed raw raw fish is ground or used as raw feed. Therefore, it is a manufacturing technology in the field of feed, which belongs to the processing technology that has been provided to cage-cultured fish species or livestock eel species by manufacturing it in an unscientific way, such as impairing digestion.

In particular, in recent years, due to many studies, the feed provided to the fish group is supplied as a compound feed, but it is not suitable as feed for the fish group, it is expensive, and there is a variety of waste from marine products that cannot be used for food, so recycling is essential. In reality, if the discarded seafood processing by-products that can be recycled and reduce breeding costs for young breeders can be manufactured as frozen wet food in accordance with the strengthened law, it will not only lead to a breakthrough in the field of waste treatment but also breeding for young fish breeders. It is also part of the processing technology expected in the field of recycled frozen wet food for rearing fish for fishery processing by-products, which also has the effect of lowering the cost.

As the background technology of the present invention, domestic patent No. 10-2014-0061791 (April 29, 2014) and domestic patent No. 10-2009-0008002 as a flounder high-efficiency EP feed composition researched and developed by the Institute of Fisheries Science and Technology as a substitute for raw feed (2002.02.06.) Non-heating soft particle feed and manufacturing method thereof, and Korean Patent No. 10-2009-0123418 (2009.12.11.) wet feed for fish farming and manufacturing method thereof, and Korean Patent Publication No. 10- Frozen feed and manufacturing method of fish of 2002-0003776 (Jan. 15, 2002) and method of manufacturing fish meal using tuna and yellow pollack by-product of publication No. 10-2017-0116676 (October 20, 2017) and Japanese Patent Application Laid-Open No. The separation and purification method of fish oil of Gaiso 62-199694 (Mar. 197.0.03.), the feed manufacturing system of Korean Patent Publication No. 10-2005-0106651 (November 11, 2005), and patented technology of numerous domestic and foreign fish feeds was the background,

In particular, the main background technology is that in view of the fact that aquatic products are perishable in terms of their characteristics and processing by-products, the most important thing is to always maintain a frozen state even when collecting and transporting waste, even if it is a waste, before decomposing. The technology was used as the background technology of this patent,

The problems to be solved in the present invention are to collect all of the discarded seafood processing by-products rich in protein in consideration of the lack of nutritional components even in the formulated feed, and then analyze the components in a set unit to identify the ingredients insufficient to supply as a fish feed. Afterwards, based on this, it is recommended to find sub-materials that can make up for the lack of ingredients and make up for them. It is recommended to produce particle feed of a good size for fish groups. This is a method of excluding stress to fish groups by forming them into cubes and feeding them.

When trying to artificially feed the fish group, there are no great conditions for the adult fish, but if there is too much fat in the fry and rear fish groups, digestion problems occur. However, since it can be a problem for the growth of bred fish, it is necessary to control and process fat, which is an important issue to be solved.

It is advantageous to produce feed in the short term without storing the generally discarded seafood processing by-products, but in terms of long-term feeding, it can be solved only by refrigeration and there is no difficulty in purchasing feed for cage breeders. The field also included this point as a task to solve in terms of making the manufacturing of this additive feed sustainable.

Due to the nature of the Busan region, where tuna fish processing business is prevalent as an outpost for deep-sea fishing boats, high-tech industry has developed in tuna processing. As it is a fatty and perishable fish, it is not accepted, so it is collected at the fishmeal feed manufacturing plant and processed into fishmeal feed. Because it is processed into liquid rather than powder, it is refrigerated for easy transport and storage, so this is adopted as a solution.

Although freezing treatment does not solve sanitation problems, it is easier to separate fat by heating at low temperatures instead of heat treatment to remove fat, which is a condition of rancidity, before freezing. If you only prevent rancidity, you don't have to worry about microbial contamination. Bacteria can be easily suppressed by freezing fish meat, but viruses must be sterilized by UV treatment. Process development that thoroughly prevents prevention should also be a solution.

In order to recycle the seafood processing by-products of the present invention, in order to process them into the fish feed required by the rearing fish farms and cage farms, the whole amount of the processed tuna by-products is crushed without heat treatment, and then hydrolyzed to separate the fat at a low temperature while transporting, and a large amount after UV irradiation. After being frozen and stored in a container in a state containing It is expected that waste companies will have the effect of resolving environmental problems,

As fish resources are depleted, aquaculture is needed due to a lack of aquatic products, but new resource feed is provided to breeding fish cages and farms that are shrinking due to lack of feed. It is expected that the effect will contribute to the solution,

Recycled frozen wet food, which is being recycled as the 'recycling frozen wet food processing method for rearing fish groups' of the present invention, has been collected and processed in various ways, and has been provided and used indiscriminately to the rearing fish groups of fish breeders, but the standard of living has changed and As the appetite for fish food has also been diversified due to many changes, and as waste treatment regulations for fishery products have become stricter domestically as well as internationally, waste aquatic products processing plants are gradually shutting down and interest in our surroundings is disappearing.

For a while, seafood processing by-products were processed into recycled fish feed rather than discarded, and received attention as livestock feed and aquaculture fish feed. The pulverization processing for work is limited, making it difficult to feed, and furthermore, while avoiding pulverization for powder that generates dust, etc., the raw materials collected after being separated into biological waste aquatic products are treated with a living body, but the crushing process without odor and dust and freezing immediately after crushing Even though it is carried out with a method that tells

First, in the process for raw material collection (the first process), waste aquatic products, which are by-products of processed seafood processing discarded in canning factories or live fish factories, are collected as raw materials, dried at high heat in a fishmeal processing factory, and then crushed. Raw materials are also received frozen, so that they do not decay immediately upon arrival, they are processed into shredded fish porridge (second process), which is crushed into living organisms in a frozen state, and processed in a liquid porridge-shaped fish porridge process instead of powder. The supplied water goes through hydro-stirring (3rd process), which is the next process of crushed fish porridge (2nd process), and is added like porridge while being stirred by adding water and rotation, and put in a drum-type low heat heater that is the next sequence of the main process. It is a heating process that involves heating and separation (4th process), which is treated with low heat while rotating. The heating and separation (4th process) releases a large amount of body fat contained in the characteristic of tuna, and is separated and processed into porridge mixed with water and fish oil. do,

When the heating process is performed for the warming separation (fourth process), the tuna body fat is dissolved in water and the fat is liberated to become porridge. In the fish meat process where only fish meat is collected in step 6-1), running water fish oil mixed with water and fat is separated and collected, and the collected running water fish oil goes through the discharge process of oil-water separation (step 6-2). The separated oil water is separated through the discharge process of separated water discharge (Step 7-2), and the fish oil is stored in a fish oil container through the fish oil process of the separated fish oil (Step 7-1) through the fish oil collection process for long-term storage. For this purpose, the refrigerated fish oil (No. 9-2) is refrigerated through the refrigeration storage process to prevent oxidative waste, and then it is commercialized as a process of supplying recycled fish oil for feed to consumers through the sales network.

The fish oil process processed into refrigerated fish oil (Step 9-2) that is not irradiated with UV light (Step 8) before storing the processed fish oil (Step 9-2) comes into contact with air when stored at room temperature. Therefore, it can be oxidized and discarded, but the ultraviolet process (the 8th process) is omitted because harmful microorganisms cannot remain inside.

The dehydrated fish meat obtained through the filtration process with drum filtration (fifth process) is separately hydrolyzed and stirred (third process), heated and separated (fourth process), and drum filtered (fifth process). Filtered fish meat (Step 6-1) if you want to use the adult fish stored in the porridge process from the crushed fish porridge (second process) collected for adult fish without going through the oil-water separation (step 6-2 process). Fish meat collected by the fish meat process in , because there is still a lot of moisture remaining, it is easy to deteriorate and goes through the irradiation process of performing ultraviolet irradiation (step 8). Before moving to the freezer, it is placed on a conveyor belt, installed on the conveyor belt, and an ultraviolet irradiation device is installed and passed through the irradiation process for ultraviolet irradiation (the 8th process) and then transferred through a sieve in a container. As the filtered fish meat (Step 6-1) contained in a container, all of the fish meat processes are contained in a moist fish meat state, so the collected filtered fish meat (Step 6-1) and separately stored adult fish are also included for storage in the freezer. It is stored as pre-cooled or quick-frozen for storage until it is distributed as frozen fish meat (process 9-1), and then supplied to end-users.

The frozen wet food prepared as described above has a high moisture content and melts as soon as it is taken out of the freezer. It can be prepared with the same feed as raw fish feed, and when feeding aquaculture fish with a general compound feed made from grains, water must be added and injected into cubes. Since it can be injected into cubes, it can be manufactured as a compound feed for fish provided as a good wet frozen cube feed.

For raw material collection (first process), if the tuna by-products generated at the tuna processing plant are processed into shredded fish porridge (second process) immediately upon arrival with a refrigeration vehicle, the tuna bones are crushed together to form a thin fish porridge, and the In the method of putting it in a container, adding the same amount of water and stirring it with water (the third step), the fat contained in the fish porridge is heated and separated (the fourth step) to liberate the body fat from water, and the fish meat, fat and water are diluted. This is because the fat that has been processed into fish porridge is easy to separate by drum filtration (the 5th process) and the fat is removed when processed into filtered fish meat (the 6-1 process) with less fat, because it is good as feed for fry.

The process performed in stages as described above is a tuna fish species with a lot of fat content, and in order to transfer even a fish porridge processed with added water, it does not flow well without a separate device for forced transfer or manual operation that requires a lot of labor costs. Because of this difficulty, hydro-stirring (3rd process) is performed for the purpose of easy transport, while warming and separating (4th process) is performed to separate fat for fry and reared fish.

Hydrogen stirring (3rd process) is a process that not only separates and collects fat but also makes it easier to transfer the fat. process), heat treatment is performed in such a way that the fat contained in a large amount of processed tuna by-products is easily released.

In drum filtration (fifth process), the filtration device covers the drum device with a filter cloth and the problem of how much water content can be separated from the running water fish oil according to the rotation speed is a method according to the rotation speed, that is, the RPM. should be set by measuring

Raw feed obtained from the eojuk process that is crushed into crushed fish porridge (the 2nd process) In order to transfer the raw fish porridge to the transport pipe installed at the bottom of the crushing device, the concentration of the crushed fish porridge must be a certain amount of liquid, so hydrolyze the When the hydrolysis process of If free fish oil is contained, it is easy to discharge from oil-water separation, so it is a factor that goes through the watering process of hydro-stirring (the third process) and the heating process of heating and separating (the fourth process), and as a result, drum filtration (the fifth process) It can be used for fattening of adult fish as feed fish oil by discharging free fat through a filtration process that discards only water and fish oil.

As described above, after hydrolyzing (3rd step) and warming separation (4th step), the drum filtration (5th step) uses a drum-type filtration device to separate and collect dehydrated fish meat and water-containing fish oil mixed with fat and water. , separated into water and fat in oil-water separation (Step 6-2), and the separated fish oil (Step 7-1) separated from water is placed in a container and refrigerated with refrigerated fish oil (Step 9-2), and the water is The entire amount is discharged to the drain pipe through the separated water discharge (Step 7-2),

The entire amount of dehydrated fish meat obtained by filtration in drum filtration (step 5) is placed in a rectangular resin container with a total amount of 20 kg. It is mounted on the middle of the belt conveyor, and the rotating spatula stirs the filtered fish porridge (step 6-1) and irradiates UV rays (step 8). When loaded onto a pallet in a packed state, one ton of pallets loaded with 6 in 3 rows of 3 rows and 10 in 4 rows in 1 row are loaded in 5 tiers and transferred to a frozen warehouse with a forklift and stored as frozen fish porridge (Step 9-1). Since it is manufactured as a wet feed for fisheries, all tuna by-products collected in the living body in the raw material collection (step 1) are treated as feed resources that cannot be thrown away except for the separation water discharge (step 7-2) that only discards the water added at the factory. could,

The frozen wet food stored in the frozen warehouse is processed by processing the tuna processed products that are discarded at the tuna processing plant collected as a living body as described above, and is supplied to a nearby livestock farm, mixed with the general fish mixture at a predetermined mixing ratio, and injected into cubes. I was able to see good growth by spraying and feeding the young fish.

In accordance with the advice of nutrition experts in the aquaculture field that there is no major obstacle to digestion and that fat content improves meat taste rather than protein content, tuna collected and stored separately is drum filtered during the processing stage of tuna fish products that are discarded in public places. After performing oil-water separation (Step 6-2), the water and fat collected in step 5) are secured as dehydrated fish oil with separated fish oil (Step 7-1), and then placed in a container for a certain amount of refrigerated fish oil (Step 9-). The whole amount collected in step 2) was refrigerated and provided to a fish farm for use only for adult fish.

In order to promote fattening, the group of adult fish puts the refrigerated fish oil (Step 9-2) in a container in a certain amount at a specified mixing ratio in a cube manufacturing device at the aquaculture compounding warehouse, mixes and mixes, and then injects and supplies into small cubes. As a result, it was confirmed that good meat quality was obtained,

Although it is only an adult fish, the fisheries researchers advise that the water temperature of the farm is maintained at a constant temperature to digest the fat. It was an opportunity to

Unlike fry or reared fish groups, adult fish of artificially reared fish grow faster and have better meat taste when they have a lot of fat. After carrying out the process), only a certain amount of fish was stored for adult fish, and then the hydro-stirring (3rd process), heating separation (4th process), and drum filtration (5th process) were omitted, and the whole amount was filtered (process 6-1). ), put in a square resin container weighing 20 kg, and transferred to a belt conveyor, passed through the UV irradiation device mounted on the middle of the belt conveyor, and processed into frozen fish porridge (step 9-1) that received UV irradiation (step 8). We were able to obtain recycled frozen wet food,
