Referring to FIG. 1, the individual quick freezing apparatus 1 according to the present invention is provided under the transfer part 11 and the transfer part 11 for transferring the refrigeration object 100, A blowing unit 12 for injecting cold air upward toward the freezing object 100, and a cooling unit 13 connected to the air blowing unit 12 and an air passage to cool air toward the air blowing unit 12. And a case 14 for accommodating the transfer part 11, the blower part 12, and the cooling part 13, and to cool the air passing through the cooling part 13 by using a refrigerant cycle. And a compressor 131, a heat dissipation unit 132, and an expansion unit 133 connected to the cooling unit 13 and the refrigerant passage 130. The frozen object 100 may correspond to a variety of objects needing a freezing operation, as well as agricultural products such as onions, strawberries and the like, such as fish.

The transfer part 11 is installed inside the case 14 in the form of a porous conveyor belt. An inlet 141 is formed at one side of the case 14 so that the inlet end 111 of the transfer part 11 is formed. Is exposed to the outside, the outlet 142 is formed on the other side of the case 14 is exposed to the outlet end 112 of the transfer unit 11 to the outside. In addition, the individual quick freezing apparatus 1 may further include a drive motor 113 connected to the transfer unit 11 to provide power for the operation of the transfer unit 11, that is, the conveyor belt. Therefore, after the refrigeration object 100 is placed on the inlet end 111 of the transfer unit 11, while passing through the cooling space 10 inside the case 14 in accordance with the operation of the transfer unit (11). The object to be frozen and completed to freeze may be discharged to the outside through the outlet 112 of the transfer unit 11.

The blower 12 is provided in the form of a fan that sucks air in both axial directions and discharges in the lateral direction. That is, intake ports for air suction are formed on both side surfaces of the blower unit 12, and discharge holes for air discharge are formed on the upper surface of the blower unit 12. Then, the transfer part 11 is placed above the blower part 12, so that the air of the blower part 12 is discharged upward toward the transfer part 11. For example, the blower 12 may be various fans within a range in which air is sucked in the axial direction and discharged in the lateral direction, such as a sirocco fan. In addition, a blower motor 121 mechanically connected to the blower 12 may be further provided as a power source for the operation of the blower 12.

At this time, since the conveying part 11 is provided with a porous conveyor belt, the air of the blowing part 12 may directly reach the freezing object 100 through the conveying part 11.

The cooling unit 13 is provided with a fin-tube type heat exchanger capable of cooling air by using a refrigerant, and both sides of the upper side of the transfer unit 11 corresponding to the ceiling of the transfer unit 11 and the case 14. It is installed in plurality in the plurality to form a cooling space 10 for the freezing object 100 to pass along with the transfer unit (11). The cooling unit 13 may be provided as a single heat exchanger on both sides of the transfer unit 11, respectively, but may be provided in plurality along the transfer unit 11 so that the cooling space 10 can be long.

Fins of the cooling unit 13 are installed side by side in the transverse direction with respect to the conveying unit 11, the air passing through the conveying unit 11 and the freezing object 100 in the transverse direction of the conveying unit 11 It guides through the cooling part 13. In addition, the air introduced into the cooling unit 13 is discharged downward of the cooling unit 13 is configured to be sucked into the suction port of the blower (12).

That is, the air passing through the transfer part 11 and the freezing object 100 is separated into two air flows toward each cooling part 13 provided on both sides of the transfer part 11 and the freezing object 100 to flow. It cools down. The cool air cooled while passing through the cooling units 13 is simultaneously introduced into the blower unit 12 through both suction ports of the blower unit 12 and combined. Then, the air passing through the blower 12 is injected upward toward the transfer unit 11 and the freezing object 100 again. Accordingly, the circulation passage of the cold air forcedly flowed by the blower 12 is formed to surround the upper surface of the cooling space 10, that is, the transfer part 11.

In this case, the blower 12 may be provided along the transfer part 11 such that cold air may be injected toward the freezing object 100 while the freezing object 100 is transferred along the transfer part 11. Can be deployed. In addition, the blowing unit 12 is continuously along the conveying unit 11 so that cold air can be continuously injected into the freezing object 100 while the freezing object 100 is conveyed along the conveying unit 11. It can be arranged as.

In addition, in order to efficiently cool and circulate the cold air toward the freezing object 100, the cooling unit 13 includes the transfer unit 11 over the entire section in which the blower unit 12 is disposed along the transfer unit 11. It can be installed continuously at a point adjacent to).

Meanwhile, the cooling unit 13 may be connected to the compressor 131, the heat dissipation unit 132, the expansion unit 133, and the refrigerant passage 130 to form a refrigerant cycle. Therefore, in the compressor 131, the heat dissipation unit 132, the expansion unit 133, and the cooling unit 13, compression-condensation-expansion-evaporation of the refrigerant occurs, respectively, so that the refrigerant cycle can be performed. Here, in the cooling unit 13, the air passing through the freezing object 100 is cooled by the refrigerant. That is, while passing through the cooling unit 13, the refrigerant absorbs heat from the air and evaporates.

Here, the cooling unit 13 is installed inside the case 14, but the compressor 131, the heat dissipation unit 132, and the expansion unit 133 may be installed outside the case 14. . Since the compressor 131 is installed outside the case 14, it is possible to prevent the cooling performance of the individual quick freezing apparatus 1 from being lowered by the heat generated by the compressor 131. In addition, since the heat dissipation unit 132 is installed outside the case 14, heat of the refrigerant passing through the heat dissipation unit 132 may be easily absorbed by the outside air.

On the other hand, the individual quick freezing apparatus 1 is installed adjacent to the conveying unit 11 so that the freezing object 100 can be uniformly spread over the entire conveying unit 11, It further includes a vibration generating unit 15 for generating a vibration for applying an external force to the freezing object (100). The vibration generating unit 15 may be applied to various vibration generating devices such as a vibrator within a range capable of applying an external force to the refrigeration object (100).

The vibration generating unit 15 is installed below the transfer unit 11 to generate a vibration to apply an external force up and down the transfer unit 11. Therefore, the freezing object 100 seated on the transfer part 11 may be spread over the entire upper surface of the transfer part 11 due to the vibration generated by the vibration generating part 15. In addition, by applying an external force up and down to the transfer unit 11 and the freezing object 100, since the freezing object 100 is floated from the transfer unit 11, evenly across the entire surface of the freezing object 100. There is an advantage that cold can hit.

In addition, the vibration generating unit 15 is continuously installed along the conveying unit 11 so that the freezing object 100 can support while the refrigeration object 100 is transported along the conveying unit 11. Can be. In addition, the vibration generating unit 15 has a center of the transfer unit 11 so that the freezing object 100 can be spread more quickly when the freezing object 100 is introduced into the cooling space 10. As a reference, it may be concentrated and installed below the transfer part 11 corresponding to the inflow side of the cooling space 10.

In addition, the blowing unit and the vibration to act on the freezing object 100 at the same time to maximize the diffusion and flotation effect of the freezing object 100, the vibration generating unit 15 is the blowing unit on the conveying unit (11) It can be installed to overlap with (12). That is, the vibration generating unit 15 may be installed at an adjacent point or overlapping the discharge port of the blower (12). Therefore, not only the cold air of the blower 12 injected upward, but also the vibration generated by the vibration generating unit 15 acts together, so that the freezing object 100 is more effectively diffused and supported throughout the transfer unit 11. Can be.

Meanwhile, the cooling space 10 is divided into a primary cooling unit 101, a secondary cooling unit 102, and a tertiary cooling unit 103, and the primary cooling unit 101 is cooled by the refrigeration. The temperature of the object 100 is gradually lowered, and in the secondary cooling unit 102, the temperature of the freezing object 100 reaches a freezing point, and the freezing of the freezing object 100 proceeds. In the secondary cooling unit 103, the temperature of the freezing object 100 frozen in the secondary cooling unit is lowered to a freezing state.

Here, the vibration generating unit 15 may be centrally installed so as to overlap the blower 12 below the transfer unit 11 corresponding to the secondary cooling unit 102. For example, in a state where a total of six blowers 12 are continuously installed in the cooling space 10, the space in which the first blower 12 is installed from the inflow side of the cooling space 10 is the primary cooling unit. Corresponding to 101, the space in which the second and third blowers 12 are installed corresponds to the secondary cooling unit 102, and the space in which the fourth to sixth blowers 12 are installed is the third cooling unit 103. Assume that the vibration generating unit 15 may be installed to overlap the second and third blowers 12.

In general, the freezing object 100 may include water in the process of being washed in advance, or may contain water itself. By the way, when the temperature of the freezing object 100 reaches a freezing point while the freezing object 100 is cooled in this state, a problem of sticking between adjacent freezing objects 100 occurs while water freezing occurs. Can be.

However, in the present invention, since the vibration generating unit 15 is intensively installed in the secondary cooling unit 102 where substantially freezing of the freezing object 100 is performed, the freezing object 100 sticks to each other. The phenomenon can be minimized, there is an advantage that the freezing object 100 can be frozen more independently and uniformly.

According to the present invention, since the plurality of refrigeration objects 100 are supported by the cold air injected upwards from below, the refrigeration quality between the plurality of refrigeration objects 100 may be uniformly distributed throughout the transfer part 11. There is an advantage that can be ensured more uniformly.

In addition, since the attitude of the refrigeration object 100 is continuously changed as the refrigeration object 100 is supported by the cold air sprayed upwards, uniform refrigeration is made throughout the single refrigeration object 100, thereby reducing moisture and There is an advantage that circular preservation can be effectively implemented.

In addition, since the blower 12 and the vibration generator 15 are installed to overlap the transfer unit 11, the blower 12 and the vibration generator 15 are not only upwardly cooled by the blower 12 but also by the vibration generator 15. By vibrating together, there is an advantage that can further maximize the diffusion and flotation effect of the refrigeration object (100). That is, the freezing object 100 is spread more quickly and uniformly throughout the transfer part 11, the freezing quality between the entire freezing object 100 can be ensured uniformly. In addition, since the separation support effect of the freezing object 100 is further maximized, the airtight time of the freezing object 100 is increased and the frequency of change of posture is increased, so that the same on the whole of the single freezing object 100 is uniform. Cooling is made that the water and the original blood preservation of the frozen object 100 can be effectively implemented.

In addition, the vibration generating unit 15 is concentrated on one side of the transfer unit 11 corresponding to the inflow side of the cooling space 10, the refrigeration object 100 flowing into the cooling space 10. This has the advantage of being able to spread more quickly and uniformly.

In addition, after the cool air circulation passage by the blower 12 passes through the cooling space 10, the cooling space 10, that is, the freezing object 100 is formed along the outer side of the cooling space 10. Since it is formed to surround the upper surface of the transport portion 11 is seated, by increasing the thermal insulation effect of the cooling space 10 can be more effectively preserved the low temperature state of the cooling space 10, the energy efficiency can be maximized There is an advantage to that.

As such, within the scope of the basic technical idea of the present invention, many modifications are possible to those skilled in the art, and the scope of the present invention should be interpreted based on the appended claims. will be.
