Description

Micro-nano oxygen bubble fish fainting and anesthesia apparatus and method

The present invention relates to a micro-nano oxygen bubble fish fascinating and anesthesia device and method for supplying micro-nano oxygen bubbles to live fish.

       As income increases, the preference for live fish dishes is increasing. The taste of the fish is determined by the freshness of the fish. Especially in the sashimi dish, the meat quality of the live fish is lively to be able to produce the fish's unique taste.

      Conventionally, live fish used for sashimi are transported from the mountain to the consumption area in a live fish tank, and live fish tanks are equipped with live fish tanks. The introduced fish breathes with dissolved oxygen in the water, and supplies oxygen by blowing air into the blower (blower) to supply the consumed oxygen, or vaporizes the liquefied oxygen from the liquefied oxygen tank and transfers it to the water. Inject and supply to.

     Actually, the oxygen supply by the above method is not enough oxygen supply, so the amount of live fish is about 10% -30% compared to the loaded fish water, so the loading is very small, thereby increasing the transportation cost.

      On the other hand, live fish are deteriorated due to stress, oxygen shortage during transportation, and long-term interruption of food administration, thereby reducing the inherent taste.

      In order to compensate for these drawbacks, live fish transportation has been carried out using various anesthesia methods such as low temperature anesthesia or acupuncture anesthesia, but only a limited amount of live fish is used.

       In recent years, as shown in [1], in Japan, pressurized water and live fish are sealed together in a pressurized tank, and then pressurized for 30 minutes to 3 hours at 2 to 5 atmospheres while pressurizing compressed air into the pressurized tank. Subsequently, the oxygen in the air is dissolved in the water while oxygen is sucked into and infiltrated into the fish body, causing the live fish to faint and anesthetized. A method for improving meat quality by promptly killing lively and anesthetized live fish for cooking has been proposed.

       Not only does this method not only finely bubble the air pressurized into the pressurized tank, but it also takes a long time to dissolve oxygen with 21% oxygen in the air, while nitrogen occupies 70% or more in the air. As the nitrogen is also pressurized into the pressurized tank, it is difficult to force this nitrogen to be discharged to the outside. Doing.

     In order to solve the above problems, liquid oxygen is used instead of air, and liquid oxygen is produced as micro-nano oxygen bubbles and pressurized into a fish accommodation tank to rapidly increase dissolved oxygen concentration to inhale oxygen into live fish Permeation of live fish to faint and anesthetize live fish at low or normal pressure.

By fainting and anesthetizing live fish, the metabolic process is stopped and adenosine acid accumulates, thereby increasing the taste of inosinic acid.

      Micro-nano-sized microbubbles are highly permeable with their diffusivity and narrow space, allowing them to easily penetrate into the muscle cells of the fish, so that the pressure in the fish tank can be operated at low or normal pressure, thereby reducing the stress on the fish. Reduced.

     Micro-nano oxygen bubbles are produced by supplying oxygen vaporized from the liquefied oxygen cylinder to the ultra-fine bubble generator to generate micro-nano oxygen bubbles, and impacting the generated micro-nano oxygen bubbles to produce nano oxygen bubbles to accommodate fish.

It shrinks and contracts, shrinks to nano-bubbles, and soon disappears, and it is confirmed that nano-bubbles of several micron-200nm (nm) survive in water for a long time. W was classified.

It was also confirmed that the micro-nano bubble having such a property survives for a long time as it is generated as a nano bubble when directly impacted at the generator.

As a method of impacting the micro-nano bubble, various methods such as an ultrasonic shock and a shock by a rotating blade have been proposed.

In the present invention, the liquid oxygen is used to generate micro-nano oxygen bubbles in a short time, and the micro-nano oxygen bubbles are impacted to infiltrate into the fish holding tank 9 to easily infiltrate oxygen into the fish muscle cells. This allows oxygen to accumulate in a short time, which causes the inside of the fish holding tank 9 to operate at or below 2 atm, or at atmospheric pressure to cause live fish to faint and anesthetize in a short time.
