Description

Technical Field

[0001] This invention belongs to the technical field of cooling and quick-freezing equipment, and more specifically, it relates to a cooling and quick-freezing equipment for steamed xiaolongbao (soup dumplings). Background Technology

[0002] Cooling is a crucial step in the production and processing of xiaolongbao (soup dumplings). However, existing cooling methods for xiaolongbao have many problems.

[0003] Traditional cooling methods often fail to ensure sufficient contact between cold air and the xiaolongbao (soup dumplings), resulting in uneven cooling and slow cooling of some dumplings, which affects overall production efficiency.

[0004] Moreover, the lack of effective airflow guidance and control measures during the cold air transmission process resulted in excessive cold air impact and uneven flow, which reduced the contact time and area between the cold air and the xiaolongbao, thus affecting the cooling effect.

[0005] In addition, the existing cooling devices are not well-designed in terms of structure, and do not make full use of the internal space of the cooling box, thus failing to achieve efficient circulation and uniform distribution of cold air.

[0006] At the same time, the way the xiaolongbao are placed during cooling is not ideal, which prevents the cold air from fully contacting the bottom of the xiaolongbao, thus limiting the cooling speed and making it difficult to meet the requirements of rapid and uniform cooling.

[0007] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a cooling and quick-freezing device for steamed xiaolongbao, in order to achieve a more practical purpose. Summary of the Invention

[0008] To address the aforementioned technical problems, this invention provides a quick-freezing device for steamed xiaolongbao (soup dumplings) after cooling, thus resolving the aforementioned issues.

[0009] A quick-freezing device for steamed xiaolongbao (soup dumplings) includes a cooling cabinet. A cooling machine is fixedly installed on the top of the inner wall of the cooling cabinet. A cooling box is fixedly installed inside the cooling cabinet. The cooling machine is located above the cooling box. At least two pull frames are equidistantly arranged inside the cooling box. At least two air vents are opened through the left and right sides of the cooling box. Each air vent on the left and right sides of the cooling box is equidistantly distributed vertically. At least two second air guide plates and a third air guide plate are fixedly installed equidistantly on the left and right side walls of the cooling box.

[0010] Preferably, an air inlet is provided on the rear side of the top of the cooling cabinet, a cabinet door is installed on the front side wall of the cooling cabinet, and exhaust ports are provided on both the left and right sides of the cooling cabinet, with each exhaust port being close to the bottom of the cooling cabinet. The air inlet of the cooling machine is connected to the air inlet. A first air guide plate is fixedly installed on the top of the cooling machine. The cross-sectional shape of the first air guide plate is arc-shaped, with the center point of the first air guide plate being higher and the left and right sides being lower. Each second air guide plate is located on the outer wall of the air inlet groove, and an arc-shaped protrusion is fixedly installed above the end of each second air guide plate. The top height of each arc-shaped protrusion is located at the center opening of the air inlet groove.

[0011] Preferably, when a second air guide plate is installed outside the air inlet slot on the left side of the cooling box, a third air guide plate is installed outside the air inlet slot on the right side of the cooling box. Each third air guide plate is located between two second air guide plates. An arc-shaped plate surface is fixedly installed on the side wall of each third air guide plate. The left side of each pull frame is open. Two support rods are fixedly installed at the bottom of each pull frame.

[0012] Preferably, each of the pull frames has an air intake frame installed inside, each air intake frame has two lower grooves, each support rod is located inside the lower groove, each air intake frame has an airflow channel inside, each airflow channel has a V-shaped cross-section, each air intake frame has an air intake pipe fixedly installed on the left side, each air intake frame has an exhaust screen fixedly installed at the upper opening, and each pull frame and exhaust screen has at least two conical blocks fixedly installed on their surfaces.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the fan directs the cooled air downwards, causing it to sink. Simultaneously, the cold air enters the air inlet slot along the second air guide plate and then enters the cooling box. The cold air comes into contact with the steamed buns above the pull frame and exits through the air inlet slot on the right side of the cooling box. This allows the cold air to circulate inside the cooling box, and the circulated air is discharged through the exhaust port. By specially designing the inlet and outlet ports of the cooling box, it is ensured that the steamed buns can be fully contacted by the cold air, thereby improving the cooling speed of the steamed buns.

[0015] In this invention, the arc-shaped convex plate can reduce the impact force of cold air and improve the smoothness of airflow. The cold air flows out through the air vent groove on the right side of the cooling box along the pull frame. After the cold air flows out, it comes into contact with the third air guide plate and flows downward along the arc-shaped plate surface. The arc-shaped plate surface can turn the airflow direction. The cold air flows down the arc-shaped plate surface to the next air vent groove. By using the air vent groove and the arc-shaped plate surface to guide and control the cold air, the contact time and area between the cold air and the xiaolongbao can be increased, thereby increasing the cooling speed of the xiaolongbao.

[0016] In this invention, since the inner wall of the cooling box is a straight wall, the use of an arc-shaped plate to change the direction of airflow can increase the speed of airflow at the corner, thereby further improving the cooling circulation capacity.

[0017] In this invention, the bottom of the xiaolongbao (soup dumpling) contacts multiple conical blocks, which can support the xiaolongbao, creating a certain gap between the xiaolongbao and the surface of the air intake frame. When cold air comes into contact with the xiaolongbao, it can not only contact the surface of the xiaolongbao but also the bottom of the xiaolongbao. By using cold air circulation from both the top and bottom sides, the cooling speed of the xiaolongbao can be further improved.

[0018] In this invention, when cold air circulates, it enters the air intake frame through the air intake pipe, then enters the airflow channel, flows within the airflow channel, and then flows upward through the exhaust net. The cold air passes through the exhaust net and contacts the bottom of the xiaolongbao, and the flow speed of the cold air decreases at the bottom of the xiaolongbao. At this time, the contact time between the cold air and the xiaolongbao can be increased, thereby improving the cooling speed inside the xiaolongbao. Attached Figure Description

[0026] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0027] Please see Figures 1-6 This invention provides a quick-freezing device for steamed xiaolongbao (soup dumplings), comprising a cooling cabinet 1, a cooling machine 14 fixedly installed on the top of the inner wall of the cooling cabinet 1, and a cooling box 15 fixedly installed inside the cooling cabinet 1. The cooling machine 14 is located above the cooling box 15. At least two pull frames 3 are equidistantly arranged inside the cooling box 15. A fan transmits the cooled air from the cooling machine 14 downwards, causing the cold air to sink. Simultaneously, the cold air enters the air inlet groove 16 along the second air guide plate 2 and then passes through the air inlet. The air enters the cooling chamber 15 through the slot 16. The cold air comes into contact with the small steamed buns above the pull frame 3 and exits through the air vent slot 16 on the right side of the cooling chamber 15. This allows the cold air to circulate inside the cooling chamber 15. At least two air vent slots 16 are provided on both the left and right sides of the cooling chamber 15, and each air vent slot 16 on the left and right sides of the cooling chamber 15 is equidistant vertically. At least two second air guide plates 2 and a third air guide plate 2 are fixedly installed equidistantly vertically on the left and right side walls of the cooling chamber 15. 2. An air inlet 13 is provided on the rear side of the top of the cooling cabinet 1. A cabinet door 11 is installed on the front side wall of the cooling cabinet 1. Exhaust outlets 12 are provided on both the left and right sides of the cooling cabinet 1, and each exhaust outlet 12 is close to the bottom of the cooling cabinet 1. The air inlet of the cooling machine 14 is connected to the air inlet 13. A first air guide plate 18 is fixedly installed on the top of the cooling machine 14. The cross-sectional shape of the first air guide plate 18 is arc-shaped. Cold air moves to the surface of the arc-shaped convex plate 21, and the arc-shaped convex plate 21 can slow down the flow of cold air. The impact of cold air improves the smoothness of airflow. The cold air flows out through the air outlet groove 16 on the right side of the cooling box 15 along the pull frame 3. After the cold air flows out, it comes into contact with the third air guide plate 22. The first air guide plate 18 is high at the center point and low on the left and right sides. Each second air guide plate 2 is located on the outer wall of the air outlet groove 16, and an arc-shaped protrusion plate 21 is fixedly installed above the end of each second air guide plate 2. The top height of each arc-shaped protrusion plate 21 is located at the center of the air outlet groove 16.

[0028] When a second air guide plate 2 is installed outside the air vent 16 on the left side of the cooling box 15, a third air guide plate 22 is installed outside the air vent 16 on the right side of the cooling box 15. Each third air guide plate 22 is located between two second air guide plates 2. An arc-shaped plate surface 23 is fixedly installed on the side wall of each third air guide plate 22. The left side of each pull frame 3 is open. Two support rods 31 are fixedly installed at the bottom of each pull frame 3. The bottom of the xiaolongbao (soup dumpling) contacts multiple conical blocks 37. The multiple conical blocks 37 can support the xiaolongbao, so that a certain gap is formed between the xiaolongbao and the surface of the air intake frame 32. When cold air comes into contact with the xiaolongbao, the cold air can not only contact the surface of the xiaolongbao. The surface can also reach the bottom of the xiaolongbao, and the cold air circulation on both sides can further improve the cooling speed of the xiaolongbao. Each pull frame 3 is equipped with an air intake frame 32, and two lower grooves 33 are opened below each air intake frame 32. Each support rod 31 is located inside the lower groove 33. Each air intake frame 32 is provided with an air flow channel 34. The cross-sectional shape of each air flow channel 34 is V-shaped. An air intake pipe 35 is fixedly installed on the left side of each air intake frame 32. An exhaust net 38 is fixedly installed at the opening above each air intake frame 32. At least two conical blocks 37 are fixedly installed on the surface of each pull frame 3 and exhaust net 38.

[0029] Working principle:

[0030] The first step involves the user opening the cabinet door 11 to cool and freeze the xiaolongbao (soup dumplings). The user then pulls out the pull-out frame 3, places the xiaolongbao on it, and returns the frame 3 to the cooling box 15. The user then closes the cooling cabinet 1, starts the cooling machine 14, which is equipped with a fan that directs the cooled air downwards. The cold air sinks and enters the air vent 16 through the second air guide plate 2, then through the air vent 16 into the cooling box 15. The cold air contacts the xiaolongbao above the pull-out frame 3 and exits through the air vent 16 on the right side of the cooling box 15. This allows the cold air to circulate within the cooling box 15, and the circulating air is then discharged through the exhaust port 12. By specially designing the inlet and outlet ports of the cooling box 15, the user ensures that the xiaolongbao are fully exposed to the cold air, thus increasing the cooling speed.

[0031] In the second step, when the cold air sinks and comes into contact with the first air guide plate 18, the cold air will sink along both sides of the first air guide plate 18 and come into contact with the second air guide plate 2. The surface of the second air guide plate 2 is arc-shaped, so the cold air will move along the surface of the second air guide plate 2. The cold air moves to the surface of the arc-shaped convex plate 21. The arc-shaped convex plate 21 can reduce the impact force of the cold air and improve the smoothness of the air flow. The cold air flows out along the pull frame 3 and then through the air outlet groove 16 on the right side of the cooling box 15. After the cold air flows out, it comes into contact with the third air guide plate 22. The cold air flows downward along the arc-shaped plate surface 23. The arc-shaped plate surface 23 can turn the direction of air flow. The cold air flows down along the arc-shaped plate surface 23 to the next air outlet groove 16. By using the air outlet groove 16 and the arc-shaped plate surface 23 to guide and control the cold air, the contact time and area between the cold air and the xiaolongbao can be increased, thereby increasing the cooling speed of the xiaolongbao.

[0032] Since the inner wall of the cooling chamber 15 is a straight wall, the use of the curved plate 23 to change the direction of airflow can increase the speed of airflow at the corner and further improve the cooling circulation capacity.

[0033] Third, after the xiaolongbao is placed above the pull frame 3, the bottom of the xiaolongbao comes into contact with multiple conical blocks 37. The multiple conical blocks 37 can support the xiaolongbao, so that a certain gap is formed between the xiaolongbao and the surface of the air intake frame 32. When cold air comes into contact with the xiaolongbao, the cold air can not only come into contact with the surface of the xiaolongbao, but also with the bottom of the xiaolongbao. The cold air is circulated from the top and bottom sides, which can further improve the cooling speed of the xiaolongbao.

[0034] When cold air circulates, it enters the air intake frame 32 through the air intake pipe 35 and then enters the air flow channel 34. The cold air flows in the air flow channel 34 and then flows upward through the exhaust net 38. The cold air passes through the exhaust net 38 and comes into contact with the bottom of the xiaolongbao. The cold air will slow down at the bottom of the xiaolongbao, which can increase the contact time between the cold air and the xiaolongbao and improve the cooling speed inside the xiaolongbao.

Many modifications and variations will be apparent to those skilled in the art.
