This is a drawing to explain the control module of the sterilizer according to .

As shown in Figure 1, the moisture-free cooking method using a sterilizer according to an embodiment of the present invention includes a storage step (S110), a washing step (S120), an inner packaging step (S130), a cooking step (S140), and a moisture removal step (S150). ) and shipping step (S160).

First, in the storage step (S110), raw materials growing in the open field or greenhouse are harvested and stored in a warehouse. At this time, the storage method, storage humidity, temperature, etc. can be varied depending on the harvested raw materials. In other words, it can be stored using various methods depending on the type of sweet potato, potato, rice, or plant.

Next, in the washing step (S120), the stored raw materials are first washed before cooking. Since this is grown in the open field or in a greenhouse to increase freshness during the storage stage and stored as harvested, foreign substances such as soil may be present in the raw materials. Therefore, in order to remove foreign substances such as dirt, the foreign substances are removed using running water or washing detergent in the washing step (S120). In addition, in order to remove the moisture existing on the outside of the raw material from which foreign substances have been removed, hot air drying or other drying methods can be used to remove moisture existing on the outside of the raw material before internal packaging.

Next, in the inner packaging step (S130), the raw materials from which external moisture has been removed are placed in an inner packaging paper and packaged internally. At this time, the inner packaging paper can be used to withstand the high temperature and high pressure that will be described later. Also, depending on the raw materials during inner packaging, the amount of raw materials introduced into the inner packaging may vary.

Next, in the cooking step (S140), sweet potatoes can be steamed using a moisture-free method or a moisture-free cooking method. Here, the moisture-free method or moisture-free cooking method is a method of cooking using the moisture remaining in the raw materials without using water. To use this method, in an embodiment of the present invention, the moisture (moisture) present on the surface of the washed sweet potato is removed in the washing step (S120). In other words, in order to use moisture-free cooking methods, the amount of moisture introduced from outside is minimized. At this time, in order to remove the moisture present on the surface of the sweet potato, the moisture present on the surface of the sweet potato can be removed by drying the moisture with hot air or by wiping the moisture by the user. Then, place the sweet potatoes from which the water (water) has been removed in a moisture-free pressure vessel for steaming sweet potatoes, and apply heat to the steamer side with the lid of the steamer closed. Then, the applied heat increases the temperature of the moisture present inside the sweet potato inside the steamer. As the temperature of the moisture inside the sweet potato increases, the moisture is converted into water vapor, and the converted water vapor increases the pressure inside the steamer. I order it. When moisture is removed in this way, it is possible to provide the effect of sterilization and sterilization during cooking, which is the effect of the moisture-free method. In addition, when sweet potatoes are steamed and heated using a moisture-free method, the sweet potatoes are heated at high temperature and pressure, thereby maintaining the sweet potato's nutrients. By being sterilized, storage at room temperature is possible, and the expiration date is also within the existing expiration date. It can be extended beyond the sweet potato recipe.

In order to use this moisture-free recipe, a high-temperature and high-pressure sterilizer 100 is used in an embodiment of the present invention.

As shown in FIGS. 2 and 3, the sterilizer 100 includes an enclosure 110, a door 120, and a control module 130.

First, the enclosure 110 is formed with an empty interior in order to introduce the inner packaged raw materials inside, and includes an opening (not shown) on one side to allow the inner packaged raw materials to be introduced from the outside. A door 120 is provided in this opening, and the door 120 is combined with the housing to prevent foreign substances from entering from the outside and at the same time prevents the pressure increased during cooking from escaping to the outside.

Next, the control module 130 is for controlling the temperature and pressure inside the enclosure and includes a temperature indicator 131, a pressure indicator 132, and a control panel 133. First, the temperature indicator 131 is digitally displayed as shown in FIG. 3, and this temperature indicator 131 displays the internal temperature of the enclosure 110. The internal temperature of the enclosure 110 may be 120 to 180 degrees. In addition, the sterilizer 100 checks the internal temperature of the enclosure 110 through the temperature indicator 131, and automatically lowers or raises the internal temperature depending on the raw materials present inside, thereby cooking the raw materials at the optimal temperature. can do. And as shown in FIG. 3, the pressure indicator 132 may display the internal pressure of the enclosure 110 in an analog manner. This pressure indicator 132 may indicate a warning when the pressure inside the enclosure 110 is higher than the reference pressure.

Next, as shown in FIG. 3, the control panel 133 includes a plurality of dials to control the temperature and pressure inside the enclosure 110. That is, the user checks the situation inside the enclosure 110 through the temperature indicator 131 and the pressure indicator 132, and controls the temperature and pressure inside the enclosure 100 using the dial on the control panel 133. You can control it.

In addition, the control panel 133 may be provided with a panel that can check the microbial concentration or contamination state inside the sterilizer 100, and the inside of the enclosure 110 is displayed as normal, normal, or dangerous depending on the contamination state. It can be provided to the user, and if the contamination is dangerous, the sterilizer 100 is automatically operated to clean the inside of the enclosure 110.

Next, in the residual moisture removal step (S150), when the purlin step (S140) is completed, the metal present inside the inner packaging material is detected using a metal detector, and the inner packaging material for which metal detection has been completed is cooled. At this time, when cooling is performed, moisture is formed on the outside of the inner packaging paper due to the temperature difference between the inside and the outside. To remove this residual moisture, a method of drying the outside of the raw material after the washing step (S120) is used. Use the same method to remove residual moisture existing on the outside of the inner packaging paper. In addition, sterilization can prevent the reproduction of microorganisms present inside the inner packaging material, further increasing the expiration date of cooked raw materials.

Next, in the shipping step (S160), the inner packaging paper from which cooking and residual moisture has been removed is externally packaged and shipped. At this time, the outer packaging is packaged by putting a plurality of pieces in one outer packaging according to the number selected by the user or purchaser. The outer packaging used here may be an outer packaging such as a box, plastic, or skintec.

According to this embodiment of the present invention, by using a moisture-free cooking method, it is possible to prevent the softness caused by using water and increase the taste and sweetness, and by using a sterilizer capable of moisture-free cooking, moisture-free cooking can be carried out safely.

The inner packaging material in the present invention has a coating liquid applied to the surface of the packaging material to prevent the input of external moisture, and may include a waterproofing material (GS) and a functional additive (G) applied to the outer surface of the packaging material.

In the present invention, a coating liquid is applied to the surface of the packaging material to discharge moisture existing inside the packaging material to the outside and prevent the input of external moisture.

Referring to Figure 8, the functional additive (G) includes a first cushioning material (G1) containing 0.1 parts by weight of polyurethane foam; An inner covering material (G2) containing 0.1 part by weight of polypropylene relative to 0.1 part by weight of the polyurethane foam and surrounding the first cushioning material (G1); An outer shell material (G3) that includes 0.1 part by weight of latex and surrounds the inner shell material (G2), is fibrous, and is mixed with the waterproofing material (GS); A second cushioning material (G4) containing 0.2 parts by weight of tetradecane and disposed between the inner shell material (G2) and the outer shell material (G3); A plurality of posts (G5) containing 0.1 part by weight of aluminum and provided on the outside of the outer shell material (G3); A plurality of coupling members (G6) containing 0.1 part by weight of styrene butadiene rubber and provided on the outside of each of the plurality of posts (G5), the width of which decreases toward the outside; An anionic polymer material (G7) containing 0.1 part by weight of p-styrenesulfonic acid (SSNa) and provided on either end of the outer shell material (G3); and a cationic material (G8) that includes 0.1 part by weight of polyethyleneimine and is provided on the other end of both ends of the outer shell material (G3).

The weight parts of the functional additives (G) such as polypropylene, latex, tetradecane, aluminum, styrene butadiene rubber, p-styrenesulfonic acid, polyethylene imine, etc. are described based on 0.1 parts by weight of the polyurethane foam.

As described above, the first cushioning material (G1) includes polyurethane foam and is disposed inside the inner shell material (G2), which will be described later. Polyurethane foam is used in various fields and is porous, so it was used as a functional additive (G) to add cushioning and sound insulation.

It is preferable that the above-described polyurethane foam contains 0.1 parts by weight. If it is less than 0.1 part by weight, the above-mentioned cushioning and soundproofing effects cannot be sufficiently expected, and if it exceeds 0.1 part by weight, there is a risk of the inner shell material (G2), which will be described later, bursting and leaking from the inner shell material (G2).

The inner shell material (G2) described above is disposed inside the outer shell material (G3), which will be described later, and includes 0.1 part by weight of polypropylene as described above, and surrounds the first cushioning material (G1).

If the polypropylene is less than 0.1 part by weight, it may not sufficiently surround the first cushioning material (G1), and there is a risk that the first cushioning material (G1) may be lost. If it exceeds 0.1 part by weight, the weight of the functional additive (G) may be excessive. It can be improved.

The polypropylene is manufactured in the form of a film and can be wrapped around the first cushioning material (G1) by heat fusion or the like. That is, the first cushioning material (G1) may be disposed inside the inner skin material (G2).

The outer shell material (G3) is a stretchable material containing 0.1 part by weight of latex, and may be fibrous while surrounding the inner shell material (G2) (the inner shell material (G2) and the second cushioning material (G4) described later). The outer covering material (G3) described above is mixed with the waterproofing material (GS) described above.

Since the above-mentioned outer covering material (G3) is fibrous, it can add toughness to the functional additive (G).

As will be explained in more detail in the following description, the second cushioning material (G4) is disposed between the outer shell material (G3) and the inner shell material (G2). Accordingly, the outer shell material (G3) wraps the second cushioning material (G4). If the latex is less than 0.1 part by weight, there is a risk that the second cushioning material (G4) may be lost because it cannot sufficiently surround the second cushioning material (G4), and if it exceeds 0.1 part by weight, the own weight of the functional additive (G) If it is excessively increased, the dispersibility of the functional additive (G) may be reduced.

The second cushioning material (G4) contains 0.2 parts by weight of tetradecane and is disposed between the inner shell material (G2) and the outer shell material (G3).

Tetradecane is a phase change material (PCM) with a melting point of about 4~6℃.

A phase change material is an energy storage material that can actively store and release heat without external factors in the form of latent heat without a change in temperature when the phase changes depending on the surrounding temperature.

In general, latent heat, which is heat that enters and exits without a temperature change when a phase change occurs, has a significantly higher amount of heat than sensible heat, which is heat that enters and exits with a temperature change without accompanying a phase change. This feature can be used to store high amounts of thermal energy or maintain temperature.

The second buffer (G4) described above includes, in addition to tetradecane, undecane, dodecane, tridecane, pentadecane, hexadecane, It may further include one or more of heptadecane, octadecane, nonadecane, eicosane, and triacontane. The melting point of the second buffer (G4) can be adjusted within the range of 1 to 30°C, which is room temperature.

The second cushioning material (G4) can surround the inner shell material (G2) in a solid state and can be accommodated inside the outer shell material (G3). The latex can be wrapped around the solid second cushioning material (G4) on a sheet and fixed by various known methods such as adhesive or fusion (thermal fusion) to wrap the second cushioning material (G4).

The first buffer G1 described above may contract or expand as the temperature changes. In particular, the volume of air accommodated in the pores may also contract or expand. When the above-mentioned first cushioning material (G1) is contracted, the cushioning effect for alleviating shock is reduced.

At this time, the second buffer material (G4) supplies latent heat to the first buffer material (G1), thereby suppressing heat shrinkage of the second buffer material (G4), thereby suppressing a decrease in the buffering properties of the second buffer material (G4). .

In addition, as the second cushioning material (G4) absorbs external heat, the first cushioning material (G1) expands as the temperature increases, thereby damaging the inner shell material (G2) and preventing it from being discharged to the outside.

As described above, the second buffer (G4) has a melting point of 4 to 6°C, so it can prevent the waterproofing material (GS) from falling below 0°C and prevent condensation from forming, and the waterproofing material (GS) can prevent thermal expansion or By suppressing heat shrinkage, the waterproofing material (GS) can be prevented from becoming wrinkled or cracked.

The second buffer (G4) described above is preferably disposed outside the first buffer (G1). Since the first buffer (G1) has insulation performance, the second buffer (G4) is positioned outside the first buffer (G1). ) When placed on the inside, it is difficult to expect the above-mentioned effect because heat exchange between the waterproofing material (GS) and the second buffering material (G4) is hindered.

As described above, the second buffer (G4) contains 0.2 parts by weight of tetradecane. If it is less than 0.2 parts by weight, it is difficult to expect a heat buffering effect, and if it exceeds 0.2 parts by weight, the inside of the outer shell material (G3) difficult to be placed in.

The anionic polymer material (G7) is provided on either end (left end in FIG. 8) of both ends of the outer shell material (G3) and may include p-styrenesulfonic acid, in addition to the hydrogel pre-polymer. It may further include. The anionic polymer material (G7) may be a mixture of p-styrenesulfonic acid and hydrogel pre-polymer (1:19 ratio) and UV cured.

It is preferable that 0.1 parts by weight of p-styrenesulfonic acid be included. However, if less than 0.1 parts by weight is used, the negative charge is not sufficient, and if it exceeds 0.1 parts by weight, the weight of the functional additive (G) is excessively increased and dispersibility is reduced. There is a problem.

The cationic material (G8) may be provided on the other end (right end in FIG. 8) of both ends of the outer shell material (G3).

Polyethyleneimine, included in the cationic material (G8), is a polymer obtained by polymerizing ethyleneimine and is known to have the highest cation density among existing materials.

Illustratively, each of the above-mentioned cationic material (G8) and anionic polymer material (G7) is piled up on a polyethylene (PE) film or latex and heat-sealed to the above-mentioned outer covering material (G3) or attached by an adhesive or the like to the outer covering material. It may be provided outside (G3).

The posts G5 include 0.1 part by weight of aluminum and are provided on the outside of the outer cover material G3. The posts G5 may have a pillar shape and may be arranged in plural numbers at predetermined intervals on the outer surface of the outer cover material G3. Aluminum is used because it is a light metal. If it exceeds 0.1 part by weight, the functional additive (G) becomes too heavy and dispersibility is reduced, and if it is less than 0.1 part by weight, the length or width is excessively reduced, which reduces durability.

Exemplarily, the inner end of the post G5 may be attached to the outside of the outer covering material G3 using a known adhesive or the like. As another example, the outer covering material G3 may have a fitting groove recessed from the outer surface to the inside, and the inner end of the post G5 may be inserted into the fitting groove.

Each of the plurality of coupling members (G6) is provided on the outer side of each of the plurality of posts (G5), and the width may decrease toward the outer side.

Here, the inner side may refer to the center side of the functional additive (G), and the outer side may refer to the radial direction side from the center side.

The waterproofing material (GS) may contain a number of units (GU) of the functional additive (G), and the above-described units (GU) are separated from neighboring units (GU) by shear force when stirring in the waterproofing material (GS), causing the waterproofing material (GU) to be separated from the waterproofing material (GS). GS), functional additives (G), and other additives can be improved in agitation.

After mixing or in the process of applying the waterproofing material (GS) to the packaging material, neighboring units (GU) become closer to each other due to electrostatic attraction between the anionic polymer material (G7) and the cationic material (G8). , the above-described coupling member (G6) of one of the neighboring units (GU) (hereinafter referred to as the first unit) is elastically deformed (compressed) by including styrene butadiene rubber (SBR), thereby forming the neighboring unit ( It enters between a plurality of coupling members (G6) provided on the outside of another one of the GUs (hereinafter referred to as the second unit).

When the binding member (G6) of the first unit passes between the binding members (G6) of the second unit, the anionic polymer material (G7) of the first unit and the cationic material (G8) of the second unit are electrostatically charged. They may be attached to each other by attraction, and the coupling member (G6) of the first unit may be elastically restored to its original shape with a width that decreases toward the outside.

At this time, the inner end of the above-mentioned first unit coupling member (G6) and the inner ends of the second unit coupling members (G6) are mutually supported and locked (locking coupling), thereby preventing the first and second units from being separated from each other. Thus, neighboring units (GU) are bonded to each other, and the electrostatic attraction of the neighboring units (GU) prevents the waterproofing material (GS) from expanding due to heat, and toughness can be added to the waterproofing material (GS).

The present invention described above with reference to the accompanying drawings is capable of various modifications and changes by those skilled in the art, and such modifications and changes not limited by the claims should be construed as being included in the scope of rights of the present invention.
