Description

Cabbage Storage Tank and Method for Storing Cabbage using Sealed Pack}

The present invention relates to a cabbage storage tank using sealed packaging packs and a cabbage storage method using the same.

A sealed packaging pack filled with cold salt water together with cabbage and sealed waterproof, a container unit storing one or more sealed packaging packs, a storage tank whose top is open to form a space for loading one or more container units and filled with a refrigerant inside, the above It includes one or more container fixing parts for fixing the container unit, and a heat exchanger part for cooling the refrigerant charged in the storage tank,

The container fixing part includes a fixing wire, one end of which is fixed to the inner floor of the storage tank, and the other end of the fixing wire, and the lower end is arranged to be fixed adjacent to the uppermost upper surface of the one or more loaded container units. By including a fixing member,

Waterproof sealed packaging packs filled with cold salt water are divided into predetermined units and stored to provide a storage tank where cabbage can be stored for a long period of time. The stored cabbage floats due to buoyancy, reducing cooling efficiency or moving during the loading stage. It relates to a cabbage storage tank and a cabbage storage method using a sealed packaging pack that prevents damage and further allows cabbage immersed in cold salt water mixed in for storage at the time of shipment to be immediately used as pickled cabbage.

Chinese cabbage (Korean cabbage, Brassica campestris L., Brassica pekinensis Pupr.), which is widely used as an ingredient in kimchi, is a low-temperature vegetable that prefers cool climates. Cabbage is usually sown around February to August and harvested 2 to 3 months later, from April to November. Cabbage is mainly harvested in the fall, and the cabbage harvested in the fall is shipped to the market by March of the following year. However, since kimchi is continuously consumed throughout the year, a constant supply of cabbage for the production of kimchi is required. As a result, a means of long-term storage of cabbage has been required to ensure a smooth supply of cabbage even during periods other than the harvest period. .

The size of the domestic kimchi market is estimated to be about 1.8 to 2 million tons per year (including 281,000 tons of Chinese imports and domestic household kimchi as of 2020), or about 5 to 6 trillion won in value. Among them, the time when cabbage for kimchi is most consumed is the winter kimchi season, and the demand for the cabbage consumed at this time cannot be met solely with fall cabbage harvested ahead of the kimchi season. To solve this problem, the development of a means for long-term storage of cabbage is required.

Meanwhile, instability in the supply and demand of cabbage due to climate change such as heat waves, heavy rain, high temperatures, and typhoons has caused not only cabbage prices to skyrocket but also vegetable prices to skyrocket, a reality that is recurring despite the government's efforts to stockpile. Therefore, stable storage technology for cabbage has become a task that needs to be developed urgently.

The kimchi business is highly dependent on raw materials, which depend on the adequate supply and price of cabbage, and the quality of kimchi is affected by the amount of sunlight and moisture content during the cabbage growing season. Domestic cabbage is harvested twice a year, and when there is a good harvest, the price plummets and the cabbage is plowed or thrown away without being harvested, causing a huge loss to the farmers. In addition, when cabbage harvests are poor, prices soar, causing price instability, making it difficult to control supply and demand, such as urgent imports from China. In Korea, spring cabbage is made for the month of June, fall cabbage is made for the two months of November to December, and winter cabbage from January to February is stored and shipped until spring cabbage is shipped. However, from July, when the spring cabbage shipment ends, high-cold-zone cabbage is produced to cover the supply until the fall cabbage shipment. In this process, the loss rate of fall cabbage due to deterioration is about 30 to 40% on average during the refrigerated storage period of about 3 to 4 months. In proportion to the storage period, the quality of cabbage is significantly deteriorating due to flavor loss and meat becoming tough due to respiration of cabbage, but no suitable solution has been proposed.

Therefore, there is a need to develop a means for long-term storage of cabbage that can smoothly meet the demand for cabbage at any time by storing and supplying cabbage for a long period of time, regardless of the harvest time.

Meanwhile, the prior art related to the storage of cabbage is,

Through the above configuration, the cabbage storage tank and cabbage storage method using the sealed packaging pack of the present invention provide the following characteristic advantages.

1) Cabbage is stored in a waterproof sealed packaging with cold salt water, and the heat that may be generated from the waterproof sealed cabbage is cooled through a refrigerant circulated through a heat exchanger, thereby lowering the temperature of the cabbage to -2 to 0℃. It makes storage possible, and by stopping the respiration and enzyme activity of the cabbage through waterproof sealing, the freshness of the cabbage can be maintained without browning or softening occurring. Therefore, it can be stored in a fresh state for 3-4 months, so it has the advantage of supplying cabbage of the same substance as cabbage harvested in season.

2) The cabbage is filled with cold salt water and stored in a waterproof seal, and the waterproof sealed cabbage can be stored for a long time in a state blocked from the refrigerant to maintain temperature, thereby enabling cooling through the refrigerant and at the same time preventing any possible occurrence. It has the advantage of completely eliminating the possibility of contamination of stored cabbage due to contamination of the refrigerant.

3) Since the salinity of the brine filled inside the sealed packaging pack and the salinity of the brine as a refrigerant filled inside the storage tank can be set differently, the temperature of the refrigerant for cooling and the salinity of the stored cabbage can be appropriately adjusted as needed. In other words, by allowing the salinity difference between the refrigerant and the cold brine to be set differently, the cabbage can be stored freshly without suffering from cold damage by setting an appropriate temperature, and at the same time, the stored cabbage can be shipped as pickled cabbage with an appropriate salinity suitable for kimchi. There is an effect.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing preferred embodiments.

In adding reference signs to the components in each of the drawings below, the same components are given the same reference numerals as much as possible even if they are shown in different drawings, unless it is judged that this may unnecessarily obscure the gist of the present invention. Detailed descriptions of the known functions and configuration are omitted.

Figure 1 is a perspective view showing a cabbage storage tank using a sealed packaging pack according to a preferred embodiment of the present invention.

As shown, the cabbage storage tank using the sealed packaging pack of the present invention,

A sealed packaging pack (1) for storing cabbage by filling cold salt water with cabbage and sealing it waterproof, a container unit (2) for storing one or more of the sealed packaging packs (1) in a predetermined unit, and one or more It forms a predetermined internal space so that one or more container units (2) can be stacked, and includes a storage tank (3) filled with refrigerant to maintain the temperature at a certain level.

The sealed packaging pack (1) is a component that waterproofly seals the cabbage for storage to completely block it from external factors (air, contamination, etc.), and is preferably made by injection using a pre-formed mold corresponding to the external shape of the cabbage for storage. A soft sealing film (eg, plastic film, etc.) manufactured by molding may be used. In addition, in a preferred embodiment of the present invention, the cabbage for storage is stored cut in half to facilitate transfer of temperature through the refrigerant to the inside of the cabbage, thereby maintaining the product temperature (temperature inside the cabbage) at a low temperature. has Therefore, when manufacturing the sealed packaging pack 1, a soft sealing film manufactured by injection molding using a mold with a shape corresponding to the shape of a cabbage cut in half can be used.

In a preferred embodiment of the present invention, the sealed packaging pack (1) is filled with saline water together with cabbage for storage. Since salt water has a lower freezing point than that of regular water (purified water, etc.), it has the property of not freezing even when the temperature drops below zero. Therefore, the present invention utilizes these characteristics of brine to extend the storage period of cabbage and prevent cold damage to the stored cabbage even if the internal temperature of the cabbage stored below freezing temperature falls.

Additionally, the saline solution serves as a sterilizing water to sterilize cabbage for storage. This utilizes the sterilizing effect due to the difference in salinity of the saline solution. By removing any bacteria that may remain even after washing with the saline solution, the marketability of the cabbage is increased and the storage period can be extended for a longer period of time by preventing spoilage caused by bacteria.

In addition, since the saline solution itself provides the effect of salting cabbage, it has the effect of allowing cabbage to be stored for a long period of time and has the advantage of providing pickled cabbage immediately when the cabbage is shipped. In other words, the cabbage stored with saline solution in the sealed packaging pack (1) is salted with cold saline water and undergoes a pickling process, and even if the cabbage stored through this process is not subjected to an additional cabbage pickling process, it is pickled cabbage used in kimchi. It can be shipped as a product. In this process, if the salinity of the cabbage stored with brine in the sealed packaging pack 1 is different from the salinity of the cabbage required as a product (for example, for kimchi), the salinity required in the washing process with purified water Since it is a cabbage that can be adjusted, it has the advantage of being able to obtain as many pickled cabbages with the desired salinity as needed.

In a preferred embodiment of the present invention, the saline solution filled with the cabbage in the sealed packaging pack (1) has a salinity of 3% to 5%. More preferably, the saline solution filled in the sealed packaging pack (1) is saline solution of different salinities depending on the weight of the cabbage. For example, when saline solution of 30% of the weight of the cabbage is filled, saline solution of 4.3% salinity, If 40% of the weight of the cabbage is filled with saline solution, a saline solution with a salinity of 3.5% can be filled, and if a saline solution that is 50% of the weight of the cabbage is filled, a saline solution with a salinity of 3% can be filled.

The reason why the salinity of the saline solution varies compared to the weight of the cabbage is that the pickling effect of the cabbage occurs due to the mixing and filling of the saline solution and the cabbage, and at the same time, the total salinity (saline solution + cabbage) inside the sealed packaging pack (1) is reduced, so the saline solution and cabbage are mixed and filled. This is to achieve 1% salinity for easy storage. Therefore, the salinity can be adjusted to 1% by varying the salinity according to the amount of saline solution filled relative to the weight of the cabbage, and the salinity can be further reduced by about 0.2% during the washing process at the time of shipment, so that pickled cabbage with a final salinity of 0.8% can be shipped.

As a result, in order to achieve the above-mentioned advantages, the sealed packaging pack (1) completely seals and vacuum-packs the cabbage with the filled brine, thereby separating the stored cabbage from air, sterilizing the cabbage, and loading it into the storage tank (3). It has the function of completely blocking the stored cabbage from the refrigerant.

As described above, the sealed packaging pack (1) is composed of a sealing film made of a soft material, preferably a soft plastic material, and the sealed packaging pack (1) of a preferred embodiment of the present invention has an upper sealing film made of a soft material. It consists of (11) and lower case film (12).

Figure 2 shows a sealed packaging pack of a preferred embodiment of the present invention constructed as described above.

The sealed packaging pack (1) is based on a pre-made mold to form a groove (corresponding to the shape of the stored cabbage) into which cabbage (preferably cabbage cut in half) is inserted into the lower case film (12). It is manufactured by injection molding, and cabbage is inserted into the lower case film 12 manufactured in this way and brine is filled.

The upper sealing film 11 covers the upper part of the lower case film 12 after the cabbage is inserted into the lower case film 12 and the filling of the brine is completed, and the edge is sealed in that state, and the vacuum packaging operation is performed. The final waterproof sealing of the sealed packaging pack (1) is achieved by removing and sealing the air and bubbles remaining inside. Adhesive adhesion and/or heat melt adhesion may be used for sealing between the upper sealing film 11 and the lower case film 12, but are not limited thereto.

The configuration of the sealed packaging pack (1) described above is only a preferred embodiment of the present invention, and in another embodiment of the present invention, a bag filled with cabbage and cold salt water, such as a plastic bag equipped with a sealing means, is used. The sealed packaging pack (1) may be configured to include other alternatives capable of being watertight sealed.

The container unit 2 is a component that allows the sealed packaging pack 1 to be loaded in predetermined units and at the same time facilitates the storage and transportation of cabbage in predetermined units at the time of shipment.

A container unit according to a preferred embodiment of the present invention is shown in Figure 3.

As shown, the container unit (2) forms an internal space so that a predetermined unit of sealed packaging packs (1) can be loaded inside, and the upper part makes it easy to load one or more sealed packaging packs (1) from the top. It is made up of an open rectangular box shape.

More preferably, the container unit 2 includes at least one outlet 21.

The discharge port 21 is a refrigerant (filled inside the storage tank 3) charged inside the storage tank 3 in the step of loading the container unit 2 into the storage tank 3 for storing cabbage. It can be provided so that the refrigerant) flows smoothly into the container unit (2) and is supplied to the sealed packaging pack (1) stored in the container unit (2), and can be quickly submerged under the water surface of the refrigerant. .

In addition, the outlet 21 is used to cool the refrigerant (storage tank 3 ) may be provided so that the refrigerant) charged inside the container unit (2) is discharged without being moved together with the container unit (2).

On the other hand, when loading a plurality of container units (2), the container unit (2) is installed along the edge of the lower part so that it can be easily combined with the upper part of another container unit (2) and fixed to the upper part. ), a container unit coupling portion 22 may be further formed that is retracted inward from the bottom or protrudes downward from the bottom of the container unit 2, corresponding to the shape of the upper end of the container unit 2.

In one embodiment of the present invention, the container unit (2) may further include a container lid that seals the open top, and the container lid is provided in each of the plurality of container units (2) or is loaded. It can be provided only in the container unit (2) located at the top of the container unit (2).

The storage tank (3) is a container unit in which one or more container units (2) containing a predetermined unit of sealed packaging pack (1) are stacked in a predetermined unit, and a refrigerant for temperature maintenance is filled therein and stacked. (2) It is a component that maintains and stores the temperature of the sealed packaging packs (1) stored inside.

A storage tank according to a preferred embodiment of the present invention is shown in Figure 4.

As shown, the storage tank 3 of the preferred embodiment of the present invention forms an internal space so that predetermined units of container units 2 can be loaded at regular intervals, and the upper part is provided for transportation of the container units 2. It consists of an open rectangular shape. However, the shape of the storage tank 3 is not limited to a rectangular shape, and in another embodiment of the present invention, the shape of the storage tank 3 is cylindrical, or a portion of the storage tank 3 is formed so that the cross-sectional area of the upper opening is smaller than the cross-sectional area of the lower portion. It may include a curved portion, or may have any shape as needed.

Meanwhile, the storage tank 3 is filled with a refrigerant for cooling the sealed packaging pack 1. In a preferred embodiment of the present invention, the refrigerant charged inside the storage tank 3 may be salt water, more preferably salt water with a concentration of 1% to 5%. However, the refrigerant of the present invention is not limited to brine, and may be replaced with purified water or other mixtures, if necessary.

The storage tank 3 is preferably buried underground so as to easily maintain a constant temperature of the refrigerant charged therein and, consequently, the temperature of the cabbage stored in the sealed packaging pack 1 loaded therein. At this time, the upper part of the storage tank 3 is buried so that it protrudes above the ground, thereby preventing contaminants from flowing into the open upper part of the storage tank 3.

In a preferred embodiment of the present invention, the storage tank 3 includes a body layer 31 forming the body of the storage tank, an insulation layer 32 forming an insulation layer along the inner surface of the body layer 31, and the storage tank 3. It has a multi-layer structure including a waterproof layer 33 that forms a waterproof layer along the inner surface of the insulation layer 32. Therefore, the innermost surface of the storage tank 3 is made of a waterproof layer 33 to prevent the refrigerant from leaking out, and the outside of the storage tank 3 is connected to the storage tank 3 through the insulation layer 32 surrounding the outside. ), the temperature of the refrigerant can be kept constant by preventing internal heat exchange.

Meanwhile, since saline water is filled with cabbage inside the sealed packaging pack 1, the specific gravity of the sealed packaging pack 1 may be small compared to the salinity of the refrigerant filled inside the storage tank. In this case, the sealed packaging pack (1) may be buoyant due to the difference in specific gravity with the refrigerant and float to the top of the storage tank filled with the refrigerant. In this case, the stored packs collide with each other due to the movement of the sealed packaging pack (1). The quality of the cabbage may be damaged, or a part of the sealed packaging pack (1) may float on the surface of the refrigerant filled in the storage tank (3), reducing cooling efficiency.

Accordingly, a container fixing part 4 described below is provided as a device for fixing the container unit 2 loaded with the sealed packaging pack 1 so that it does not move.

It can be. However, it is not limited to this, and in one embodiment of the present invention, the cover support part 6 may include only one or more horizontal bands 61 or one or more vertical bands 62.

Meanwhile, a storage tank lid portion 7 may be further included to seal the upper part of the storage tank 3 after all the cargo is loaded into the storage tank 3.

Preferably, the storage tank lid portion 7 also includes an insulating material, and this can prevent the temperature of the refrigerant from being heat exchanged with the outside through the open top of the storage tank 3. More preferably, the storage tank lid portion 7 may be made of a multi-layer structure including the same insulation layer and waterproof layer as the storage tank 3.

The storage tank lid portion 7 can close the storage tank 3 with the cover portion 5 and the cover support portion 6 disposed between the storage tank lid portion 7 and the storage tank 3. It is desirable to configure it so that

Meanwhile, a heat exchanger unit (8) connected to the storage tank (3) is further included.

Figure 8 shows a heat exchanger unit according to a preferred embodiment of the present invention.

The heat exchanger unit 8 is a device for maintaining a constant temperature of the refrigerant filled inside the storage tank 3, and the temperature generated by salting the cabbage sealed with saline solution in the sealed packaging pack 1 It is provided to maintain the temperature of the refrigerant that has risen or fallen due to an increase or decrease in heat exchange between the external temperature and the internal temperature of the storage tank 3 at a preset temperature.

In a preferred embodiment of the present invention, the refrigerant charged in the storage tank 3 may be brine having a salinity of 2% to 5%, more preferably 3% to 4%. Therefore, while maintaining the refrigerant temperature at a sub-zero temperature, freezing of the refrigerant consisting of salt water is prevented, and as a result, the temperature of the cabbage packed inside the sealed storage pack 1 can be maintained at a temperature of -2 to 0°C. You can.

In a preferred embodiment of the present invention, the heat exchanger unit 8 includes a refrigerant inlet pipe 81 that introduces the refrigerant into the storage tank 3, and a refrigerant outflow pipe that flows the refrigerant out of the storage tank 3 ( 82), a heat exchanger 83 connected to the refrigerant inlet pipe 81 and the refrigerant outlet pipe 82 to exchange heat of the refrigerant, a pump 84 that generates circulation of the refrigerant, and a heat exchanger that lowers the temperature of the heat exchanger. It includes a chiller (85).

The pump 84 operates when the internal temperature of the storage tank 3 rises/falls, and the refrigerant charged into the storage tank 3 is discharged from the refrigerant outflow pipe 82 by the operation of the pump 84. The leaked refrigerant is lowered/increased in temperature to a preset temperature through the heat exchange unit 83 and flows back into the storage tank 3 through the refrigerant inlet pipe 81. At this time, cooling of the heat exchanger 83 is performed through the chiller 85, and heat exchange between the chiller 85 and the heat exchanger 83 may be performed through a refrigerant containing salt water. Through the above-described process, the temperature of the refrigerant charged in the storage tank 3 can be kept constant at a preset temperature (for example, -2 degrees to -0 degrees).

Hereinafter, the cabbage storage process using the cabbage storage method using the sealed packaging pack of the present invention having the above configuration will be described step by step with reference to FIG. 9. Figure 9 shows each step of the cabbage storage method using a sealed packaging pack according to a preferred embodiment of the present invention.

1) Step of washing cabbage for storage (S001)

Cabbage for storage is first washed prior to storage. At this stage, contaminants on the cabbage are washed and the cabbage is ready for storage.

2) Cabbage cutting step for saline solution filling (S002)

At this stage, the cabbage for storage is cut longitudinally from the cabbage root and separated into halves. Generally, cabbage used in kimchi has multi-layered leaves that begin to grow at the root. Therefore, the internal temperature (product temperature) of the cabbage may be insulated by several layers of cabbage leaves, resulting in a temperature difference from the outside. This characteristic prevents all parts of the cabbage from being cooled to a constant temperature when stored, so the quality of the cabbage may be damaged during cooling. Therefore, in the step described later, the cabbage is cut in half and prepared so that the saline solution can be quickly injected into the interior of the cabbage to quickly and uniformly cool the temperature of the cabbage.

3) Inserting the cut cabbage into a sealed packaging pack with cold salt water and sealing it waterproof (S003)

As described above, the sealed packaging pack (1) is equipped to accommodate cabbage and saline solution for storage together and to seal and package them in a waterproof manner.

In a preferred embodiment of the present invention, the saline solution filled with the cabbage in the sealed packaging pack (1) has a salinity of 3% to 5%. More preferably, the saline solution filled in the sealed packaging pack (1) is saline solution of different salinities depending on the weight of the cabbage. For example, when saline solution of 30% of the weight of the cabbage is filled, saline solution of 4.3% salinity, If 40% of the weight of the cabbage is filled with saline solution, a saline solution with a salinity of 3.5% can be filled, and if a saline solution that is 50% of the weight of the cabbage is filled, a saline solution with a salinity of 3% can be filled.

In this step, the cabbage cut in the step (S002) and saline water are injected into the sealed packaging pack (1) together, and a vacuum packaging operation is performed to remove air and bubbles remaining inside, and at the same time, the sealing is performed. The upper sealing film 11 of the packaging pack 1 is attached to the lower case film 12, thereby completing the final waterproof sealing packaging of the cabbage.

4) Step of storing waterproof sealed sealed packaging packs in a container unit in predetermined units (S004)

In the above step (S003), the cabbage that has been vacuum-packed and packaged in a waterproof sealed packaging pack (1) is stored in a container unit (2) in predetermined units. As described above, the container unit 2 is a means provided to store and transport the cabbage packed in the sealed packaging pack 1 in predetermined units, and is configured to facilitate stacking, so that it is stored inside the storage tank 3. is loaded on

5) Step of adjusting the temperature of the refrigerant charged inside the storage tank to the preset temperature (S005)

Separately from the above-described steps, a step of presetting the temperature of the refrigerant charged inside the storage tank 3 is performed. In this step, by cooling the temperature of the refrigerant in advance before the cabbage is loaded into the storage tank 3, rapid cooling can be achieved from the time the cabbage is loaded.

In a preferred embodiment of the present invention, the refrigerant charged in the storage tank may be brine having a salinity of 2% to 5%, more preferably 3% to 4%. Therefore, while maintaining the refrigerant temperature at a sub-zero temperature, freezing of the refrigerant consisting of salt water is prevented, and as a result, the temperature of the cabbage packed inside the sealed storage pack 1 can be maintained at a temperature of -2 to 0°C. You can.

6) Step of loading the container unit (2) containing a predetermined unit of sealed packaging pack inside the storage tank (S006)

After the internal temperature of the storage tank is set through the above steps, the step of moving and loading one or more container units 2 containing sealed packaging packs 1 in predetermined units into the storage tank is performed.

At this stage, when two or more container units 2 are loaded in the storage tank, the container units 2 are arranged vertically to each other and loaded. In other words, the second container unit is placed on top of the first container unit 2, and the third container unit is placed and loaded on top of the first container unit 2.

In addition, in a preferred embodiment of the present invention, the plurality of container units (2) are arranged in one set of four container units (2), so that the four container units (2) are arranged in one stage, and the other four containers are placed on top of the four container units (2). It is preferable to stack in such a way that four container units (2) are arranged to form a second stage, and another four container units (2) are arranged on top of them to form a third stage. At this time, four container units must be loaded in one stage at the same time so that the top height is the same. This corresponds to an arrangement to correspond to the use of the container fixing part 4, which will be described later. In the present invention, the maximum height at which the container units 2 are loaded is not particularly limited, and is preferably corresponding to the internal height of the storage tank 3.

Additionally, at this stage, separate means may be used to facilitate transportation of the container units 2 in a stacked state. This means may be, for example, a pallet, and the pallet is first placed prior to loading the container unit 2, and one or more container units 2 are loaded on top of the placed pallet to load the container unit 2 on a pallet basis. It can be loaded into the storage tank (3).

7) Step of placing the fixing member of the container fixing unit on the top of the loaded container unit and fixing the container unit (2) (S007)

When the loading of the container unit 2 is completed through the above steps, the fixing member 42 of the container fixing part 4 is placed at the uppermost part of the loaded container unit 2. Since the upward movement of the fixing member 42 is restricted by the fixing wire 41, it prevents the loaded container unit 2 from moving upward due to buoyancy and prevents the loaded container unit 2 from moving upward due to buoyancy. It can be fixed.

8) Step of installing the cover support on the top of the storage tank (S008)

When the loading of all container units 2 and fixing their positions through the container fixing part 4 is completed through the above steps, the cover support part 6 for installing the cover part 5 before closing the opening of the storage tank 3. ) is installed. As described above, in the cover support part 6 of the present invention, after the cover part 5 formed of a soft material is placed on the upper part of the reservoir 3, the center of the cover part 5 is located in the reservoir 3. It is a component provided to prevent sagging to the inside, and is disposed at the lower part of the cover part 5.

9) Step of placing a cover portion on top of the cover support portion (S009)

When the installation of the cover support part 6 is completed through the above steps, the cover part 5 is placed on top of the cover support part 6. At this stage, the cover part 5 is preferably installed to cover the entire open portion of the upper part of the storage tank 3. Therefore, the cover part 5 prevents contaminants from entering through the upper opening of the storage tank 3 or air from entering the storage tank 3, thereby preventing contamination of the refrigerant filled in the storage tank 3 or a decrease in cooling efficiency. can do.

10) Step of sealing the upper part of the storage tank with the storage tank lid (S010)

Once the installation of the cover part 5 is completed in the above step, the upper part of the storage tank 3 is finally sealed with the storage tank lid part 7, thereby completing the storage of the cabbage.

11) Maintaining the temperature of the internal refrigerant in the storage tank at a preset temperature (S011)

When the storage operation of the cabbage for storage is finally completed through the above steps, the temperature of the refrigerant in the storage tank 3 is continuously maintained constant through the heat exchanger unit 8 during the storage period of the cabbage.

12) Step of removing stored cabbage (S012)

After the storage of the stored cabbage is completed, a step of removing the loaded container units 2 to the outside of the storage tank 3 is performed to ship the stored cabbage product. At this stage, all of the stored cabbages may be taken out, or only some of the stored cabbages, that is, some of the container units 2 containing the waterproof packaged cabbages may be taken out.

At this time, prior to moving the loaded container unit 2 for movement of the container unit 2, the container fixing part 4 disposed on the container unit 2 is first released, and the container fixing part 4 ), the loaded container unit 2 is moved.

13) Step of washing and shipping stored cabbage (S013)

The cabbage taken out of the storage tank 3 through the above step (S012) is separated from the sealed packaging pack 1, washed using purified water, and shipped as a pickled cabbage product. At this stage, if the salinity of the cabbage stored with brine in the sealed packaging pack (1) is different from the salinity of the cabbage required as a product (for example, for kimchi), the salinity required during the washing process with purified water is adjusted. It can be adjusted as a cabbage. As a result, the cabbage stored through this process can be shipped as a pickled cabbage product used in kimchi even without performing an additional cabbage pickling process.

In a preferred embodiment of the present invention, the stored cabbage separated from the sealed packaging pack (1) at this stage has a salinity of 1%. Therefore, the salinity can be further reduced to about 0.2% through a washing process with purified water, and ultimately, pickled cabbage with a marketable salinity of 0.8% can be shipped.

Although the preferred embodiment of the cabbage storage tank and cabbage storage method using the sealed packaging pack of the present invention has been described above in detail, this is merely a specific example to aid understanding of the present invention and limits the scope of the present invention.
