(Aging Apparatus under Below-zero Condition and Aging Method therewith)

The present invention relates to aging, and more particularly, to an ultra-low-temperature aging method capable of aging meat at a temperature below a freezing point and a method of aging using the same.

When slaughtering livestock, post stiffness occurs immediately after slaughter but gradually softens and flavor improves over time. The period during which these changes are progressed is called the aging period, and leaving the meat during that period is called aging.

Aging can be classified into dry aging and wet aging. Dry ripening means naturally evaporating and leaving the moisture of meat, while wet ripening means putting it in a plastic bag or a sealed plastic container to keep the moisture in a preserved state.

The main body 110 may be constructed of a rectangular heat insulating structure having a front side opened and a side side and a rear side closed, and a storage room may be provided therein. The storage room can store aged objects in some areas. The aged object may be meat such as beef, pork, chicken, and fish such as mackerel and lobster. The object to be aged can remain unfrozen even at a temperature below the freezing point of the object to be aged in the storage chamber.

The main body 110 may include a first separator plate 121 and a second separator plate 125 therein.

The first separator plate 121 may be installed in a vertical direction to separate the storage chamber into a first space S10 in the direction of the door 140 and a second space S20 in the direction of the cooling unit 160. [ The first space S10 occupies most of the space in the storage room and the second space occupies some space in the direction away from the door 140. [ The second space S20 is an area in which the inside air or the outside air cooled by the cooling unit 160 moves. The first separator plate 121 may have a plurality of first through holes H10. The first through-hole H10 can move the cool air in the second space to the first space.

The second separator plate 125 may be vertically spaced apart from the first separator plate 121 in the direction of the door 140. The second separation plate 125 may form a maturation space S11 for storing the aged object in the first space and a cold transition space S13 between the aged space and the first separation plate 121. [ The cold transfer space is an area where the inside air circulates and is cooled by being mixed with cold air flowing through the first through hole H10 of the first separator plate 121. [ The second separator plate 125 may include an inner air inlet IN10 having a shape of a slit, a tube, or the like, for example, on the upper side or the lower side. The inner air of the aging space can be moved to the cold transfer region through the inner air inlet IN10. Although the figure shows that the inside air is introduced, it may be brought out. However, it may be preferable to construct it so that it is easy to cause natural convection in the aging space. 2 separator 125 may have a plurality of second through holes H20. The second through-hole H20 can move the inner air cooled in the cold transfer space to the aging space in the door 140 direction. Of course, if the internal air cooled through the internal air inlet IN10 is discharged, the second air hole H20 moves the internal air of the aging space to the cold transfer space.

A shelf support part for supporting the shelf 130 may be provided on the inner wall of the main body 110 constituting the storage room.

The shelf 130 stores the object to be aged, and can be coupled to the shelf support portion provided on the inner wall of the storage chamber and can be seated. The shelves 130 may be vertically spaced and stacked. The shelf 130 may have a contact blocking portion 131 protruding upward along the edge. The contact blocking portion 131 can prevent the aging object loaded on the shelf 130 from contacting the inner wall of the storage chamber. The inner wall of the storage chamber is lower in temperature than the aging space, so that when the aging object comes into contact with the inner wall of the storage chamber, the aging object can be frozen, and the contact blocking portion 131 can block such contact.

The door (140) is coupled to the front of the main body (110) to selectively open and close the front opening of the storage compartment. The door 140 may be rotatably coupled with the front side of the main body 110 on one side thereof as a rotational axis. The door 140 has a heat insulating structure, and at least a part of the door 140 can be made of a transparent material that can identify the inside of the storage compartment. The transparent material may be glass, and in this case, it can be composed of heat-strengthening glass. The heat-strengthening glass is a thermally insulated coil inserted between multiple glasses, which can be used to control the temperature and humidity of the storage compartment.

The inner air circulating fan 151 is located on the upper inner wall of the storage room to smoothly move the air in the aging space to the space between the first partition plate 121 and the second partition plate 125 have. The internal air circulation fan 151 can be positioned above the storage compartment. The internal air heated in the aging space moves upward by the convection, and when the internal air circulating fan 151 moves to the cold transfer space, the internal air can be cooled down in the cold transfer space and move downward.

The internal air circulating fan 151 can move the internal air of the aging space to the cold transfer space at the lower end of the storage compartment when the second air separator 125 has the internal air inlet IN10 at the lower end thereof. In this case, a separate blowing fan may be provided at the lower end of the cold transition space.

It may be preferable that the internal air circulating fan 151 does not directly blow wind into the aging space. For this purpose, the internal air circulating fan 151 preferably introduces the internal air into the cold transfer space. When the cooled internal air in the cold transfer space is discharged, the air flow direction is directed toward the wall of the storeroom, The air guide portion may be spaced apart at a predetermined interval so that the cooled inside air is blown between the storage chamber wall and the air guide portion.

The inner air circulating fan 151 may also function to circulate the inside air. In this case, the circulating speed of the circulating fan is adjusted to set the circulating speed of the inside air to, for example, 0.5 to 3.5 m / s, 2.5 m / s.

When the evaporator 165 is positioned on the lower side or the side of the main body 110, a separate cool air circulating fan for moving the cool air upward may be provided.

The temperature sensor 170 can be installed in the aging space or the cold transfer space of the storage room, the cold air passage of the cooling unit 160, and the like. The temperature sensor 170 can measure the temperature values of the aging space, the cold transition space, and the cold moving path.

The control unit 180 controls the cooling unit 160 and the like on the basis of the temperature value received from the temperature sensor 170 to adjust the temperature of the storage room, especially the aging space, in the range of -4 to 0 占 폚, In the range of -5 to 0 ° C. When the temperature of the aging space falls below -2 DEG C, the control unit 180 can control the temperature by setting an error range for temperature control so as to restore the temperature to -2 DEG C. [ For example, if the error range is set to ± 0.5 ° C, the control unit 180 can stop the cooling unit 160 when the temperature of the ripening space becomes -2.5 ° C, and when the temperature of the ripening space becomes -1.5 ° C The cooling unit 160 can be operated. The control unit 180 sets the upper temperature limit value to 0 占 폚 to maintain the zero-temperature condition.

The controller 180 controls the temperature of the internal air to be minimized by sequentially changing the first and second separator plates 121 and 125 having the first and second through holes H10 and H20 described above, And circulating the inside air to the fan 151 to minimize the temperature difference according to the position of the inside air.

The ultra low temperature aging board of the first embodiment may further include an external air inlet IN30 and an external air inlet fan 155. [ The external air inlet IN30 is a passage for communicating the outside of the main body 110 with the cooling unit 160, and may be formed in the form of a slit, a tube, or the like. The external air suction fan 155 is installed adjacent to the external air inlet IN30 to smoothly move the air outside the main body 110 toward the evaporator 165 of the cooling unit 160. [

The ultra low temperature aged ware of the first embodiment may have a wood panel on the inner wall of the storage room, preferably the inner wall of the aged space. The wood panel can be made of wood such as oak, white wood. Wood panels can perform functions such as deodorization, antibacterial and humidity control, and can enhance the flavor by pilling the wood fragrance during aging (especially, in the case of dry aging).

The ultra-low temperature aging board of the first embodiment can be provided with a heater. The heater can serve to minimize temperature changes in the storage compartment. The heater can be installed in the cold transferring space S13 between the first and second separating plates 121 and 125 and the cold moving path of the cooling unit 160, that is, the second space S20.

The ultra-low temperature aging of the first embodiment may include an oxygen generator. The oxygen generator supplies oxygen to the maturing space, which keeps the color of the meat red and improves the meat taste.

2 is a detailed view showing the first and second separation plates in the ultra-low temperature aging furnace of the first embodiment.

As shown in FIG. 2, the first separator plate 121 may include a plurality of first through holes H10, and the second separator plate 125 may include a plurality of second through holes H20. The first through hole H10 of the first separator plate 121 moves the cool air generated by the cooling unit 160 to the cold air transition space and the second through hole H20 of the second separator plate 125 moves the cold air The inside air which is mixed with the inside air and the cold air is moved to the aging space. The first and second through holes H10 and H20 may have various shapes such as a circle, an ellipse, and a square.

The first through-hole H10 and the second through-hole H20 may be arranged to be shifted from each other in the horizontal direction. Through this zigzag arrangement, it is possible to prevent the cold air, which has moved to the cold transferring space through the first through hole H10, from moving into the aging space through the second through hole H20 without being sufficiently mixed with the inside air in the cold transferring space And further, it is possible to improve the mixing of the cold air and the internal air in the cold transfer space.

The first embodiment is provided with a through hole opening / closing part B10 which can be engaged with the first and second through holes H10 and H20 of the first and second separator plates 121 and 125 to close the first and second through holes H10 and H20 can do. If it is difficult to connect the through-hole opening / closing portion B10 to the first through-hole H10 of the first separator plate 121, only the second through-hole H20 of the second separator plate 125 is allowed to communicate with the through- B10). The through-hole opening / closing part B10 may be an elastic stopper made of an elastic material such as rubber or silicone.

As shown in Fig. 3, in the first embodiment, the contact blocking portion 131 of the shelf 130 may be a network of a mesh structure. The mesh size of the mesh may vary depending on the size of the aged object. The mesh may be made of iron, plastic, wood or the like.

4 is a cross-sectional view showing a modified example of the ultra-low temperature aged hull of the first embodiment.

As shown in Fig. 4, the ultra-low temperature aging board of the first embodiment may be provided with an auxiliary blowing fan 157. Fig. The auxiliary blowing fan 157 can be used for supplementing the internal air circulation function of the internal air circulating fan 151.

 The auxiliary blowing fan 157 can be installed at the lower end of the storage room. The auxiliary blowing fan 157 can raise the cold inside air moving downward by the natural convection so as to evenly mix the inside air in the aging space. As a result, it is possible to increase the circulation speed of the internal air and to minimize the temperature deviation according to the position of the aging space, and as a result, the aging of the aged object can be effectively performed.

In addition, the auxiliary blowing fan 157 can be configured not to directly inject wind into the aging space. To this end, the auxiliary blowing fan 157 may guide the air blowing direction toward the wall of the storage room, or may be spaced apart from the wall of the storage room by a predetermined distance to allow the air to be blown to move between the storage room wall and the air guide .

The remaining constituent elements are the same as the constituent elements explained in Fig. 1, so that the description of the remaining constituent elements will be replaced with the corresponding explanation of Fig.

Fig. 5 is a cross-sectional view showing another modified example of the ultra-low-temperature aging crown of the first embodiment.

As shown in Fig. 5, the ultra-low temperature aging board of the first embodiment may include a cold air outlet OUT10 and a cold air discharge fan 159. [

The cool air discharge port OUT10 selectively discharges the cool air generated by the cooling unit 160 by cooling the inside air to the outside. The cool air discharge port OUT10 has a shape such as a slit or a tube at one side of the cool air passage, . The cold air outlet OUT10 can be selectively opened and closed through a cap or the like. When the cool air is discharged to the outside through the cool air outlet (OUT10), the cool air temperature is lowered and the temperature of the aging space can be raised. Further, when the cool air is discharged to the outside through the cool air outlet (OUT10), the inside air is reduced, and as a result, the inside air in the aged space is reduced, and a vacuum effect can be seen in aging.

The cool air discharge fan 159 is provided adjacent to the cool air discharge port OUT10 to facilitate the discharge of the cool air.

The remaining constituent elements are the same as the constituent elements explained in Fig. 1, so that the description of the remaining constituent elements will be replaced with the corresponding explanation of Fig.

FIG. 6 is a cross-sectional view showing a cryogenic aging cow of the second embodiment according to the present invention, and FIG. 7 is a detailed view showing the cryogenic temperature aging cow of the second embodiment.

The method of generating cold air in the ultra-low temperature aging of the second embodiment is different from that of the first embodiment. Hereinafter, parts different from those of the first embodiment will be mainly described, and description of the same similar components will be omitted from the related description of the first embodiment.

As shown in Figs. 6 and 7, the second embodiment can have one separator plate 126 for separating the storage chamber. In the second embodiment, the portion corresponding to the first separator plate 121 of the first embodiment may be a plate or a wall of the evaporator which is integrally formed with the evaporator 166. The plate may be a separate plate to be combined with the evaporator 166, but since it can also be seen as an evaporator wall, in the second embodiment, the portion that generates cold is referred to as the evaporator wall.

The separation plate 126 may form a maturing space for storing the aging object in the storage room and a cold transfer space between the aging space and the evaporator wall 122. The separator plate 126 may be configured in the same manner as the second separator plate 125 of the first embodiment. However, in the second embodiment, the internal air moved to the cold transfer space may be cooled by the evaporator wall 122 and then moved to the aging space through the through hole H20 of the separator plate 126. As described above, the second embodiment takes a method in which the inside air is cooled in the evaporator wall 122 and then returned to the aging space without the process of mixing the inside air and the cool air.

The temperature sensor 170 may be installed in the aging space or the cold transfer space of the storage room, the evaporator wall 122, and the like.

8 is a cross-sectional view showing a modified example of the ultra-low temperature aged core according to the second embodiment.

As shown in Fig. 8, the ultra-low temperature aging board of the second embodiment may be provided with an auxiliary blowing fan 157. Fig. The auxiliary blowing fan 157 is the same as the auxiliary blowing fan 157 in Fig.

A method of ultra-low temperature aging of meat or the like using the ultra-low temperature aged hull of the first and second embodiments described above will be exemplified as follows.

The control unit 180 controls the cooling unit 160 based on the temperature value received from the temperature sensor 170 to maintain the temperature of the ripening space in the range of -4 to 0 占 폚. For example, the control unit 180 sets the temperature of the fermentation space at -2 ° C for the beef, and controls the temperature of the cooling unit 160 at -2 ° C to 0.5 ° C, that is, -2.5 ° C Off and can be turned on at -1.5 [deg.] C. Even under this control, the temperature of the aging space can be changed from -2.5 ° C and -1.5 ° C down to -3.8 ° C, up to -0.5 ° C, and even down to -4 ° C and up to 0 ° C. In spite of this temperature change, the control unit 180 continuously controls the temperature of the maturing space to keep the frozen point of the beef at -2 DEG C, so that even when the temperature change occurs, the temperature change amount and the change rate are minute, Beef can be kept in a freezing state, that is, in a supercooled state.

Furthermore, the ultra-low temperature aging method according to the present invention can circulate the air inside the aging space to prevent freezing of beef. Even if the internal temperature of the aging space falls below -2 캜, which is the freezing point of the beef, circulating the inside air makes the temperature of the inside air uniform in the aging space, and as a result, , Which can substantially help to keep the beef in a non-frozen state, i.e., in a supercooled state.

In this way, while controlling the temperature of the aging space around the freezing point of the beef, the controller 180 operates the internal air circulation fan 151 to continuously circulate the internal air while minimizing the temperature change amount and the rate of change . The auxiliary blowing fan 157 can be operated when the internal air circulation fan 151 does not have enough internal air circulation. It is preferable to adjust the circulation speed of the internal air to a range of 2 to 2.5 m / s, and if this control is difficult, it may be adjusted to a range of 0.5 to 3.5 m / s.

In the ultra-low temperature aging method according to the present invention, the vinyl packaging shuts off the cool air to some extent in the case of wet aging by wrapping with vinyl or the like. Thus, the controller 180 controls the temperature of the aging space to be lower than the dry aging, It can be controlled within the range of 5 to 0 占 폚.

The freezing point of pork and chicken is -2.8 ℃, -1.7 ~ -2.2 ℃, which is slightly different from the freezing point of beef. However, while maintaining the temperature of aging room in the range of -4 ~ 0 ℃, Pork and chicken can be stored, that is, aged, in a state of not freezing, that is, in a supercooled state.

Although the present invention has been described based on various embodiments, it is intended to exemplify the present invention. Those of ordinary skill in the art will appreciate that variations and modifications may be made to the embodiments based on the above embodiments.
