Description

Technical Field

[0001] The present invention relates to a steaming device, and more particularly to a steaming device, wherein the steam input amount can be reduced by spraying steam from the side of a transfer device for conveying objects to be cooked, and the equipment operation and management costs can be reduced. Background Art

[0002] The steaming device is a device for cooking / sterilizing the food to be cooked, such as dumplings, by applying high-temperature and high-pressure steam to the food to be cooked, for example. The food to be cooked can be cooked / sterilized in the steaming device and then made into a product.

[0003] Figure 1 To illustrate the structure of a steaming device according to the prior art, Figure 2 The diagram shows the structure of a spray device (20) of a steaming device according to the prior art.

[0004] A steaming device according to the prior art comprises a conveying device (10) for conveying an object to be cooked (K), a spraying device (20) for providing steam to the object to be cooked (K), and a main frame (30).

[0005] The transfer device (10) is constructed in the form of a net.

[0006] The spray device (20) comprises a pipeline and a nozzle. The pipeline of the spray device (20) comprises a central pipe (22) parallel to the travel direction of the transfer device (10) and a branch pipe (24) extending from the central pipe (22) in a lateral direction and intersecting the travel direction of the transfer device (10). A nozzle (26) is arranged in the branch pipe (24).

[0007] The main frame (30) is configured as a storage container capable of withstanding high-temperature and high-pressure steam.

[0008] like Figure 1 As shown, in the steaming device according to the prior art, the spraying device (20) is arranged at the lower part of the transfer device (10) (net). Figure 2 As shown, the spraying device (20) includes a branched pipe, and the pipes and nozzles are evenly distributed over the entire area of ​​the lower part of the transfer device (10).

[0009] Therefore, in the steaming device according to the prior art, steam is ejected in the direction toward the ground as shown by arrow L. The ejected steam collides with the lower part of the main frame (30) and then rises and contacts the object to be cooked (K) located above the transfer device (10).

[0010] Therefore, in the steaming device according to the prior art, unnecessary heat dissipation loss of the device occurs. In addition, due to the large distance between the nozzle and the object to be cooked (K), the steam will spray to the floor and wall surfaces, thereby generating heat loss.

[0011] In other words, in the steaming device according to the prior art, only a part of the steam is transferred to the object to be cooked (K), and the remaining steam is lost in the form of equipment / conveyor heat loss or exhaustion loss. Therefore, there is a problem of an increase in the necessary input amount of steam and an increase in equipment operating costs.

[0012] Furthermore, in the prior art, since the steam supply pipe is distributed at the lower part of the transfer device (10), when organic matter (oil, solid matter, etc.) and the like fall from the object to be cooked (K), these matters may firmly adhere to the pipe and the nozzle under the net. At this time, the organic matter may be carbonized due to the high temperature (99° C. or higher) and may remain. Therefore, there is a problem that the nozzle is clogged or the product is contaminated by carbonized matter.

[0013] Therefore, in order to prevent nozzle clogging and maintain product quality, it is necessary to regularly clean and manage the organic matter. At this time, the existing steaming device has many places to be cleaned because the pipelines are distributed in a range corresponding to the entire area of ​​the net. In addition, in order to access the pipelines, the net of the steaming device must be completely disassembled and reassembled after cleaning, which requires a lot of manpower and time.

[0014] Therefore, it is necessary to develop a steaming device that can reduce steam input and reduce operating and management costs. Summary of the invention

DETAILED DESCRIPTION

[0040] Hereinafter, embodiments according to the present invention will be described with reference to the accompanying drawings.

[0041] Figure 3 FIG. 1 is a diagram showing the structure of a steaming device according to an embodiment of the present invention. Figure 4 This is a diagram showing an example of the appearance of a main frame (100) of a steaming device according to an embodiment of the present invention. Figure 5 2 is a diagram showing the structure of an injection device (300) of a steaming device according to an embodiment of the present invention. Figure 6 To magnify Figure 3 Region A of FIG. 1 shows in detail the structure of the injection device ( 300 ) of the steaming device according to one embodiment of the present invention.

[0042] The steaming device according to an embodiment of the present invention comprises: a main frame (100); a transfer device (200) which passes through the main frame (100) and moves the object to be cooked; and a spray device (300) which is located in the main frame (100) and on the side of the transfer device (200).

[0043] The main frame (100) is configured to have a container shape having an internal space. The internal space of the main frame (100) can be used as a steam space filled with high-temperature and high-pressure steam. The main frame (100) can be formed of a material having strength. Therefore, the high-temperature and high-pressure steam can be filled in the interior of the main frame (100). At both ends of the main frame (100), there may be an inlet and an outlet through which the transfer device (200) described below can pass. In the accompanying drawings, the specific shape of the main frame (100) is omitted, and the main frame (100) may have any structure in which the transfer device (200) is movable and can be filled with high-temperature and high-pressure steam. Figure 4 An example of the appearance of the main frame (100) is shown. However, the appearance and configuration of the main frame (100) are not limited to Figure 4 In addition, although the internal structure of the main frame (100) is not illustrated, the internal structure of the main frame (100) will obviously be clearly understood by ordinary technicians.

[0044] The transfer device (200) is located in the main frame (100) and passes through the main frame (100).

[0045] The transfer device (200) is a device capable of moving the food to be cooked placed on the transfer device (200). According to an embodiment, the transfer device (200) may be a device in the form of a conveyor belt that moves in a predetermined direction. Figure 3 and Figure 5 As shown by arrow F.

[0046] According to an embodiment, the transfer device (200) may include a transfer line. The transfer line may include a predetermined belt line, on which the object to be cooked may be placed.

[0047] According to an embodiment, the transfer line may be a net. In other words, the object to be cooked may be placed on the net. Therefore, not only the upper surface of the object to be cooked but also the lower surface of the object to be cooked may be in contact with the steam. Therefore, more efficient steaming may be performed. In addition, the contact area between the object to be cooked and the transfer line may be reduced. Therefore, the object to be cooked may be prevented from adhering to the transfer line.

[0048] The transfer line may include a plurality of transfer lines. The plurality of transfer lines may be arranged in multiple layers at predetermined intervals in a vertical direction. The object to be cooked may be placed on each transfer line. Therefore, a plurality of objects to be cooked may be simultaneously moved while steaming is performed.

[0049] The spraying device (300) includes a pipe portion (310) extending in the same direction as the conveying direction of the object to be cooked, and a nozzle portion (320) connected to the pipe portion (310) and receiving steam and spraying the steam to the outside.

[0050] The pipe part (310) may include a predetermined pipe. The pipe part (310) may be connected to an external steam generating device to receive steam, and may transmit the received steam.

[0051] According to the embodiment, Figure 3 As shown, the pipe part (310) may be provided at the side of the transfer device (200). Here, the side refers to the edge along two side directions. In other words, the pipe part (310) may be located at the ends of the transfer device (200) in two side directions, and the pipe part (310) may extend in the same direction as the conveying direction of the transfer device (200) conveying the object to be cooked. In other words, the pipe part (310) may extend in a direction parallel to the extension direction (travel direction) of the transfer device (200).

[0052] Here, Figure 3 The tube (310) is shown to be located inside the edges of the two lateral directions of the transfer device (200). However, the present invention is not limited thereto. In other words, the tube (310) may be located outside the edges of the two lateral directions of the transfer device (200), or the tube (310) may be located at a position overlapping with the edges of the two lateral directions of the transfer device (200).

[0053] Furthermore, as described above, when a plurality of transfer lines are provided, the tube portion (310) may be located between the plurality of transfer lines in the vertical direction.

[0054] The nozzle part (320) is a predetermined nozzle device connected to the pipe part (310). The nozzle part (320) may include a plurality of nozzle parts. In other words, a plurality of nozzle parts (320) may be connected to one pipe part (310).

[0055] like Figures 6 to 8 As shown, according to an embodiment of the present invention, the nozzle portion (320) may be configured as a through hole formed in the tube portion (310). In other words, according to an embodiment, the nozzle portion (320) may have a spray hole configured in the form of a through hole that passes through the side of the tube portion (310) and has a penetration direction (direction angle) in a specific direction.

[0056] like Fig. 9 As shown, according to an embodiment of the present invention, each nozzle portion (320) may have a configuration including a nozzle body (322) protruding from the tube portion (310) and a spray hole (324) formed in the nozzle body (322). In other words, the configuration of the nozzle portion (320) is not limited thereto, and any nozzle that can spray steam transmitted from the tube portion (310) may have an integral structure.

[0057] The nozzle part (320) is opened toward the inner side of the transfer device (200). Therefore, the nozzle part (320) can spray steam from the outer side of the transfer device (200) toward the inner side of the transfer device (200).

[0058] When the steaming device according to the prior art in which the spraying device (300) is disposed below the transfer device (200) and provides steam in an upward direction is compared with the steaming device according to the embodiment of the present invention, the steaming device according to the embodiment of the present invention has the following effects.

[0059] As described above, in the embodiment of the present invention, the pipe part (310) and the nozzle part (320) constituting the injection device (300) are located at both sides of the transfer device (200). Therefore, steam is provided by a side injection method in which steam is injected from the left and right sides of the transfer device (200) toward the center thereof.

[0060] Therefore, in the steaming device according to the embodiment of the present invention, the humidity and temperature of the internal space of the main frame (100) can be quickly increased by steam, and unnecessary equipment heat dissipation loss can be reduced. In addition, in the steaming device according to the embodiment of the present invention, since the steam input amount can be reduced, the steaming efficiency can be improved compared with the steaming device according to the prior art.

[0061] In addition, in the steaming device according to the embodiment of the present invention, compared with the steaming device according to the prior art, since the heat dissipation loss of the equipment is reduced and the steam input amount is reduced, the number of pipes and nozzles required to supply steam to the same amount of steamed objects can be reduced.

[0062] In addition, in the steaming device according to the embodiment of the present invention, the spraying device (300) is located at both sides of the transfer device (200). Therefore, even if various by-products (e.g., various organic substances produced by dumpling wrappers / stuffings, etc.) produced by the cooked food fall, the by-products will not affect the spraying device (300).

[0063] Therefore, the equipment operation and management costs of the steaming device can be reduced.

[0064] According to an embodiment, the nozzle portion (320) may include a plurality of nozzle portions. In other words, one tube portion (310) may have a plurality of nozzle portions (320). In this case, the plurality of nozzle portions (320) may be arranged to be separated from each other by a predetermined distance. For example, the distance between the nozzle portions (320) may be 8.5 cm.

[0065] At this time, at least one of the plurality of nozzles (320) can spray steam in a first direction, and at least one of the plurality of nozzles (320) can spray steam in a second direction. At this time, the first direction has a first angle with the horizontal plane, the second direction has a second angle with the horizontal plane, and the size of the first angle can be different from the size of the second angle. The horizontal plane can refer to a ground plane or an upper surface of the transfer device (200).

[0066] In other words, the nozzle portion (320) may be described as including at least one first nozzle portion (320A) and at least one second nozzle portion (320B), and the opening direction of the first nozzle portion (320A) may be different from the opening direction of the second nozzle portion (320B).

[0067] Here, the opening direction refers to the penetration direction of the through hole constituting the nozzle portion (320). Since the first nozzle portion (320A) and the second nozzle portion (320B) have different opening directions, the injection direction of the steam ejected from the first nozzle portion (320A) may be different from the injection direction of the steam ejected from the second nozzle portion (320B). In other words, the nozzle portion (320) may include a nozzle portion (320) having different injection directions of the ejected steam. That is, the first nozzle portion (320A) and the second nozzle portion (320B) may have substantially the same configuration and may be conceptually distinguished according to different opening directions. In other words, the first nozzle portion (320A) differs from the second nozzle portion (320B) in the penetration direction of the through hole and its steam injection direction.

[0068] Here, the nozzle part (320) spraying steam in a predetermined direction is not limited to spraying steam in a specific direction and a specific spatial range. Basically, because the steam sprayed from the nozzle part (320) is diffused.

[0069] As described in the above embodiment, since the nozzle part (320) with different spraying directions is provided, steam can be supplied three-dimensionally and the food to be cooked can be steamed uniformly. Therefore, the steaming efficiency can be improved.

[0070] According to a specific embodiment, Figures 6 to 8 As shown, the nozzle portion (320) may include a first nozzle portion (320A), a second nozzle portion (320B) and a third nozzle portion (320C). Figure 6 yes Figure 3 A magnified image of area A. Figure 7 A diagram showing the tube portion (310) viewed from the direction in which the nozzle portion (320) is formed, and Figure 8 Shown from Figure 7 The formation position of each nozzle part (320) when viewed in the XX direction.

[0071] At this time, the first nozzle part (320A) may spray steam in a first direction (W1) indicated by an arrow F1. In addition, the second nozzle part (320B) may spray steam in a second direction (W2) indicated by an arrow F2. Furthermore, the third nozzle part (320C) may spray steam in a third direction (W3) indicated by an arrow F3.

[0072] Here, spraying the steam in a specific direction may mean that, as described above, the spray hole (324) provided in the nozzle part faces a specific direction and guides the steam spray in the corresponding direction.

[0073] like Figure 8 As shown, the first direction (W1) may have a first angle (A) with the horizontal plane (L), the second direction (W2) may have a second angle (B) with the horizontal plane (L), and the third direction (W3) may have a third angle (C) with the horizontal plane (L). The first angle (A), the second angle (B) and the third angle (C) may be different in size from each other.

[0074] Therefore, the nozzle part (320) can spray in at least three directions.

[0075] Therefore, three-dimensional supply of steam is possible, and the food to be cooked can be uniformly steamed. Therefore, the steaming efficiency can be improved. In particular, when there are three spraying directions as in the present embodiment, the temperature deviation of the left, middle and right sides of the transfer device (200) can be reduced.

[0076] According to a more specific embodiment, the first angle (A), the second angle (B) and the third angle (C) may be respectively 0° to 90°.

[0077] According to an embodiment, the first angle (A), the second angle (B) and the third angle (C) may be 0°, 22.5° and 45° respectively. However, the present invention is not limited thereto, and each angle may be changed according to process conditions and the like.

[0078] Here, each angle is downward from the horizontal plane (L), such as Figure 8 shown.

[0079] Therefore, the first nozzle part (320A) can supply steam to the object to be cooked located at a position relatively far from the pipe part (310) (i.e., the object to be cooked located in the middle of the transfer line). And the third nozzle part (320C) can supply steam to the object to be cooked located at a position relatively close to the pipe part (310) (i.e., the object to be cooked located outside the transfer line). Therefore, a uniform steaming effect can be provided for a plurality of objects to be cooked on the transfer line.

[0080] In addition, according to one embodiment, the nozzle portion (320) may include a nozzle array (320L) in which a first nozzle portion (320A), a second nozzle portion (320B) and a third nozzle portion (320C) are arranged in sequence, and a plurality of the nozzle arrays (320L) may be disposed along the tube portion (310).

[0081] Therefore, steam can be supplied uniformly and three-dimensionally as described above, and the steaming effect can be further improved.

[0082] Comparison and contrast between the steaming device according to the embodiment of the present invention and the steaming device according to the prior art are described below.

[0083] In the steaming device according to the prior art, the steam supply pipe (spraying device (20)) is distributed below the net (transferring device (10)). Therefore, in the steaming device according to the prior art, the steam is sprayed in the direction of the ground, and the sprayed steam collides with the lower part of the net and rises, and contacts the to-be-cooked object located above the net. In addition, since the distance between the nozzle and the to-be-cooked object is large, the steam is sprayed toward the floor and wall surfaces, thereby generating heat loss. Therefore, unnecessary equipment heat dissipation loss is generated, and the steam input amount is increased.

[0084] In contrast, in the steaming device according to the embodiment of the present invention, the pipe part (310) of the spraying device (300) is installed on both sides of the transfer device (200), and the pipe part (310) extends in a direction parallel to the moving direction of the transfer device (200). Therefore, in the steaming device according to the present invention, steam is sprayed from both sides of the transfer device (200), so that the sprayed steam can directly contact the object to be cooked at a relatively close distance. Therefore, the heat dissipation loss of the equipment can be reduced, and the amount of steam input can be reduced.

[0085] In addition, in the steaming device according to an embodiment of the present invention, the steam injection angle of the nozzle portion (320) is a predetermined angle from the horizontal plane (according to one embodiment, 0°, 22.5° and 45°), and since the nozzle portions (320) have a predetermined distance from each other (according to one embodiment, 8.5 cm), the deviation of the steam injected toward the left side, right side, and central part of the transfer device (200) can be minimized.

[0086] Therefore, the basic unit of steam can be reduced by about 15% to 20% compared with the existing usage. Here, the basic unit of steam means the amount of steam per kg required per ton of steamed material.

[0087] In other words, the basic unit of steam of the steaming device according to the prior art is 837.11 kg / ton, while the basic unit of steam of the steaming device according to the embodiment of the present invention can be about 697.74 kg / ton. In other words, the steaming device according to the embodiment of the present invention can reduce the amount of steam. Therefore, it can be confirmed that, compared with the steaming device using the injection device (20) having the existing pipeline structure, in the steaming device including the injection device (300) according to the present invention, the amount of steam required to maintain the same set temperature is reduced by about 16%.

[0088] Furthermore, in the steaming apparatus according to the embodiment of the present invention, as the number of the nozzle parts (320) is reduced, the convenience of operation and management of the steaming apparatus can be significantly improved.

[0089] In the steaming device according to the prior art, since the steam supply pipe is distributed below the net (transfer device (10)), when organic matter generated by the food to be cooked falls, the organic matter may firmly adhere to the pipe and nozzle under the net. At this time, the organic matter may be carbonized due to the high temperature (99°C or higher) and may remain. Therefore, in order to prevent the nozzle from being blocked and maintain the product quality, it is necessary to regularly clean and manage the organic matter. At this time, there are many places in the existing steaming device that need to be cleaned, such as Figure 2 As shown, because the pipelines are distributed in a range corresponding to the entire area of ​​the net. In addition, in order to access the pipelines, the net of the steaming device should be disassembled and reassembled after cleaning, which requires a lot of manpower and time.

[0090] In contrast, in the steaming device according to the embodiment of the present invention, the pipe part (310) and the nozzle part (320) are located on the left and right sides of the transfer device (200) instead of being located below it. Therefore, there may be no organic matter accumulated on the pipe part (310) and the nozzle part (320), or the amount of organic matter accumulated on the pipe part (310) and the nozzle part (320) can be greatly reduced. In addition, in the steaming device according to the embodiment of the present invention, when cleaning, without disassembling the transfer device (200), only the pipe part (310) and the nozzle part (320) located on the left and right sides of the transfer device (200) are cleaned, thereby significantly improving the manpower and time required for cleaning.

[0091] Table 1 below shows the effects of the steaming device according to an embodiment of the present invention compared with the prior art in a tabular form.

[0092]

[0094] As shown in the above table, it can be confirmed that, compared with the steaming device according to the prior art, the steaming device according to the embodiment of the present invention has the effects of reducing the amount of steam used, reducing the management points according to the number of nozzles, eliminating the need for disassembly for cleaning, reducing cleaning time and manpower, and preventing organic matter from falling and contaminating the injection device (300).
