DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Mucin is a mucin substance secreted from the mucous membranes of living organisms, called mucin or point, difficult to dissolve in water and neutral salt solution, precipitated in acidic, alkaline and viscous liquid phase.

Mucins are largely classified into animal mucins and vegetable mucins, but the following description will be made with respect to animal mucins.

The chemical main body of mucin is a glycoprotein, which contains several glycoproteins depending on the origin of mucus. By way of example, there is a submandibular mucin, but the structure of the pig, It is very different. Other examples include stomach mucin, small intestine mucin, angiomyosin, cervical mucin, and the like. Digestive mucin protects organs and acts as a lubricant for digestive motility, and gastric mucin is used for gastric hyperplasia and gastric ulcer.

In addition, mucin contains chondroitin, a natural complex substance such as collagen, elastin, and protein, so it is said that mucin prevents moisture loss from external harsh environment and prevents drying of skin and quick regeneration of scarred skin.

Thus, mucin is a new substance that gives acne scars, sensitive skin regeneration and elasticity.

FIG. 4 is a detailed functional configuration diagram of a stressor according to an embodiment of the present invention. FIG. 5 is a detailed functional configuration diagram of a circular tunnel according to an embodiment of the present invention. FIG. to be.

The system 100 for extracting mucin from the eel dermis secretion collected from the eel skin by collecting and collecting a large amount of secretion from the eel skin is composed of an atmospheric water tank 1000, a stressor 2000, A circular tunnel section 3000, a high-speed centrifuge section 4000, a mucin concentration section 5000, and a freeze-drying section 6000.

The atmospheric water tank 1000 includes a plurality of eels of at least one eel stored in a water tank having a height of 1.5 * 0.7 * 1 meter in a first stage at a first water temperature for a first time, (One or more than one inlet hole 1200, one or more outlet holes 1300) and a flat plate shape, and one or more holes (through holes) are formed in the water tank 1100, And a lift steel plate 1400 which is raised and lowered by the corresponding operation.

The water tank 1100 has a length, height, and height of 1 meter * 0.5 meters * 1 meter, and one or more inflow holes 1200 for introducing water into the water tank 1100 And one or more discharge holes 1300 for discharging the water in the water tank 1100 to the outside are formed in the lower part or the lower part.

Experiments were conducted by injecting 50 adult eels into the water tank 1100. The steel plate 1400 is formed in a flat plate shape and has one or more through holes (holes) of a size free from the passage of water or through which the eel can not pass. The steel plate 1400 is connected to a device such as a string or gear, Or falls.

The lifting plate 1400 is operated to pull out or discharge the adult eel introduced into the water tub 1100 to the outside of the water tub 100.

The material of the water tank 1100 can be any one of stainless steel, wood, and plastics, but stainless steel is preferably used for uniform result and overall maintenance.

The water tank 1100 is filled with water for eel to a height of 70 to 80 centimeters for a first time by a first water temperature by a first step and water for an eel is filled by a second step for a second time by a second water temperature of 30 to 40 centimeters The water for the eel is filled.

Wherein the first water temperature is any one value selected from the range of 20 to 25 degrees Celsius and the second water temperature is any one value selected from the range of 5 to 10 degrees Celsius.

Also, the first time is any value selected from the range of 4 to 6 hours, and the second time is any value selected from the range of 10 to 20 minutes.

On the other hand, the first water temperature is preferably set to 21 degrees Celsius, and it is confirmed by experiments that the eel is stressed when it is set to be less than 20 degrees or more than 26 degrees. It is preferable to set the first time to 5 hours. If it is set to be less than 4 hours, the stabilization ratio in which the eel is adapted to the environment and is gentle is 70% or less, and if it exceeds 6 hours, .

The second water temperature is preferably set at 6 degrees Celsius. If the water temperature is set to less than 5 degrees or more than 11 degrees, it is confirmed that the eel is overcome the stress environment because there is no significant difference in the stress state in which the eel is subjected to stress. It is preferable to set the second time to 12 minutes, and it is confirmed that when the setting is set to less than 10 minutes and the setting time is more than 21 minutes, there is not much change in the stress state of the eel, thereby overcoming the stress environment.

In the first step of stabilizing the eel, 75 centimeters of the water in the water tank is preferable, and when it is less than 70 centimeters, it takes a lot of time to stabilize, and when it exceeds 81 centimeters, there is not a big difference.

Therefore, in the first step, the water temperature, which is the temperature of the water, is set at 21 degrees in the water tank 1100 having a width * length * height of 1 * 0.5 * 1 meter and staying for 5 hours stabilizes the eel in the optimum state . When changing the size of the water tank 1100 and the number of adults in the eel, it is very natural that all the experimental results should be re-examined.

In the second step of applying the primary stress to the eels, when the water height in the water tank 1100 is maintained at 30 to 40 centimeters, it is confirmed that the eels are adjacent to each other and are stressed with each other, The most stressful cases are identified. On the other hand, it is confirmed that the height of the water in the water tank 1100 is remarkably adapted when the height is kept below 30 centimeters or when the height exceeds 41 centimeters.

The eel, which is located inside the water tub 1100 and has undergone the first stress by the second step, moves to the stress part 2000 by the operation of the lifting plate 1400.

The stress unit 2000 is installed in a path along which the eel moves, and is configured to apply a stimulus to the skin of the eel for a third time period by any one or more of illumination, electric stimulation, and ultrasound.

On the other hand, the stress unit 2000 includes a mucin sensor not shown in the figure at an intermediate portion of the path to detect (measure) the amount of secretion or amount of mucin from the skin of the eel and to do. The control unit analyzes the detected data and determines whether mucin or secretion corresponding to the amount equal to or higher than the first reference level is secreted from the skin (epidermis) of the eel.

If the appropriate amount (dose) of secretion or mucin is not detected from the skin (epidermis) of the eel by the control unit in an appropriate capacity available for commercial use or above the first reference level, a stronger stimulation signal So that stronger stress is applied to the skin of the eel so that secretions or mucins are secreted from the skin of the eel.

In addition, the control unit analyzes the data detected by the mucin sensor and determines that secretions or mucins are secreted from the skin of the eel below the second reference level, which is difficult to commercially use from the skin of the eel, And when it is determined that the eels are moving, the travel path switching unit is driven so that the eels are returned to the waiting water tank. Although not shown in the drawing, the movement path switching unit can use or generally adopt a movement path switching structure of an eel.

The eel returning to the atmospheric reservoir returns to the skin through the first and second steps after releasing the secretion to the skin with time, and the amount of secretion or mucin is measured from the mucin sensor.

On the other hand, the above-mentioned 3 hours consisted of any one value selected from the range of 3 minutes to 10 minutes, and it was confirmed that maintaining the 5 minutes gave the greatest amount of stress to the eel and the amount of the secretion was great. It is confirmed that the amount of secretion decreases.

The stress unit 2000 has a length of 2 meters as a whole and 100 watts (W) of incandescent lamps 2100 are installed at intervals of 50 centimeters at a position of 1 meter on the upper side of the path. One or more The electric stimulation needle 2300 and the ultrasonic vibrator 2200 of the ultrasonic vibrator 2200 are installed along the longitudinal direction.

The incandescent lamp 2100 is configured to repeatedly flicker at a time value selected from the range of 0.2 seconds to 1 second. When the flashing is repeated at intervals of 0.4 seconds, the adult eel is the most stressed and moves actively .

The ultrasonic transducer 2200 can use one or more of the same or similar circular ultrasonic transducers for a general humidifier as the maximum output state and repeat the transverse or longitudinal direction.

The electric stimulation needle (2300) is a module structure that is protruded by a length of 2-3 millimeters in a unit area of 5 centimeters in width and 5 centimeters in length, and each needle is disposed at intervals of 1 centimeter in the front, back, left and right.

Applying a pulse signal having a frequency of 500 to 1000 hertz to each needle of the electric stimulating needles 2300 at a voltage of 5 to 6 volts (V) and a current of 1 to 1.5 amperes (A) causes the stress of the adult eel to be stressed It is confirmed that many secretions are discharged from the skin.

If the frequency of the signal applied to each needle of the electrical stimulation needle 2300 exceeds the range of 500 to 1000 hertz, exceeds the voltage range of 5 to 6 volts, or exceeds the current range of 1 to 1.5 amperes, The amount of the secretion collected is not greatly changed and it is confirmed that the efficiency is a problem.

The ultrasonic transducer 2200 and the electric stimulation needle 2300 may be alternately installed along the longitudinal direction of the stress portion 2000 or may be repeatedly installed by any one of them or alternatively, As shown in FIG.

In addition, it is preferable to control the stress intensity to gradually weaken within the allowable range from the inlet portion where the eel enters the stress portion 2000 to the exit portion where the eel comes out, in order to advance the eel.

The circular tunnel part (3000) is constituted to pass through the adult eel and contact the skin of the eel and scrape off the secretion from the skin of the eel.

The circular tunnel portion 3000 includes an eel tunnel 3100, a scraping portion 3200, a hole 3300, an electric stimulation needle 3400, an ultrasonic oscillator 3500, a support plate 3600, .

The circular tunnel part 3000 is installed on the eel exit side of the stress part 2000 and one or more of them are disposed adjacent to each other to improve the productivity of collecting the eel skin.

The circular tunnel part 3000 includes a 1-meter-long cylindrical eel tunnel 3100 formed in a direction in which an eel is moved and one or more hard rubber material scratches 3200 in direct contact with the eel's body circumference, 3100) at a uniform interval along the longitudinal inner surface.

Scratches (3200) are scaly and are arranged to maintain an inclination angle of 5 per 100 minutes in the direction of the eel, which contacts the skin of the eel and scrape the secretions from the skin of the eel in a mechanical manner, And is collected by the collecting tray 3700 through the hole 3300 while falling downward by gravity.

The inner bottom surface of the eel tunnel 3100 is relatively flat and a plurality of holes through which collected secretions are formed and at least one of the electric stimulation needle 3400 and the ultrasonic transducer 3500 is disposed in the width direction or the longitudinal direction Respectively.

When one or more of the electric stimulating needles 3400 and the ultrasonic transducer 3500 are installed in the longitudinal direction, the same position as the installation position of the scratching part 3200 is provided in three to five stages like the scratching part 3200 Is preferable for collecting secretions from the eel skin.

The support plate 3600 is in the form of a flat plate, and a hole 3300, an electric stimulation needle 3400, and an ultrasonic vibrator 3500 are formed or installed. The collecting tray 3700 is installed in a drawer shape capable of being drawn out at the lower end of the hole 3300 formed in the receiving plate 3600, and collects collected collected matter.

The eel passed through the circular tunnel part 3000 is kept in the living state since the secretion is removed from the skin (epidermis) and then the water is returned to the water tank. After about 2 hours, the eel skin is restored to the normal state Is confirmed. That is, there is an advantage that the eel can be recycled.

The high-speed centrifugal separator 4000 is operated by any one value selected from the range of 1,000 to 15,000 rpm by inputting the collected secreted material from the circular tunnel part 3000 and has a generally known constitution, Can be separated and removed.

The mucin concentration unit 5000 adds ethanol in a range of 45 to 55 wt% based on the weight of the secretion passed through the high-speed centrifugal separator 4000, reacts in a state of being stirred for 30 minutes to 1 hour and 20 minutes, Lt; RTI ID = 0.0 > mucin < / RTI >

That is, the substance precipitated or floated by the mucin concentration unit 5000 is collected in a state in which the mucin is concentrated and is generally known. The addition of ethanol at 50 wt% is the most effective way to minimize the time required for the separation of mucin into a concentrated state.

The freeze-drying unit 6000 is configured to obtain a mushin in powder form by spraying the concentrated mucin at a temperature of minus 120 degrees Celsius and freeze-drying it, and has a generally known chamber configuration.

Therefore, there is an advantage of efficiently extracting mucin from the secretions collected from the skin of the eel.

It is quite obvious that the composition of the present invention as described above can be applied to all mollusk animals other than eel.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
