[0002] In the production and processing of steamed buns, the cooling process is crucial. However, there are many problems with the existing steamed bun cooling methods.

[0003] Traditional cooling methods usually cannot ensure that the cold air is in full contact with the dumplings, resulting in uneven cooling. Some dumplings cool slowly, affecting overall production efficiency.

[0004] Moreover, during the cold air transmission process, there is a lack of effective airflow guidance and control measures, which causes the cold air to have excessive impact force and uneven flow, reducing the contact time and area between the cold air and the dumplings, affecting the cooling effect.

[0005] In addition, the existing cooling device is not rational in structural design, and the internal space of the cooling box is not fully utilized, and the efficient circulation and uniform distribution of cold air cannot be achieved.

[0006] At the same time, the placement of the dumplings during cooling is not ideal, and the cold air cannot fully contact the bottom of the dumplings, resulting in limited cooling speed and difficulty in meeting the needs of fast and uniform cooling.

[0007] Therefore, in view of this, the existing structure and defects are studied and improved, and a device for cooling and quick freezing of steamed dumplings after steaming is provided, in order to achieve a purpose with more practical value. Summary of the invention

Exhaust ports 12 are provided on both sides of the cooling cabinet 1, and each exhaust port 12 is close to the bottom of the cooling cabinet 1. The air inlet of the cooling machine 14 is connected with the air inlet 13. A first air guide plate 18 is fixedly installed above the cooling machine 14. The cross-section of the first air guide plate 18 is arc-shaped. The cold air moves to the surface of the arc-shaped convex plate 21, and the arc-shaped convex plate 21 can slow down the The impact force of cold air improves the smoothness of air flow, and the cold air flows along the pulling frame 3 and then flows out through the air outlet groove 16 on the right side of the cooling box 15. After flowing out, the cold air contacts the third air guide plate 22, and 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 convex plate 21 is fixedly installed above the end of each second air guide plate 2, and the top height of each arc-shaped convex plate 21 is located at the center opening of the air outlet groove 16.

[0028] When the second air guide plate 2 is installed outside the air outlet groove 16 on the left side of the cooling box 15, the third air guide plate 22 is installed outside the air outlet groove 16 on the right side of the cooling box 15. Each third air guide plate 22 is located between the two second air guide plates 2. The side wall of each third air guide plate 22 is fixedly installed with an arc-shaped plate surface 23. The left side of each pulling frame 3 is in an open state. Two supporting rods 31 are fixedly installed at the bottom of each pulling frame 3. The bottom of the steamed bun contacts a plurality of conical blocks 37. The plurality of conical blocks 37 can prop up the steamed bun, so that a certain gap is formed between the steamed bun and the surface of the air inlet frame 32. When the cold air contacts the steamed bun, the cold air can not only contact the surface of the steamed bun, but also the surface of the air inlet frame 32. The surface can also contact the bottom of the steamed buns, and cold air is circulated on the upper and lower sides, so as to further improve the cooling speed of the steamed buns. An air intake rack 32 is installed inside each pulling frame 3, and two lower grooves 33 are provided under each air intake rack 32. Each support rod 31 is located inside the lower groove 33. An air flow channel 34 is provided inside each air intake rack 32, and the cross-section 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 rack 32, and an exhaust net 38 is fixedly installed at the opening above each air intake rack 32. At least two conical blocks 37 are fixedly installed on the surface of each pulling frame 3 and the exhaust net 38.

[0029] Working principle:

[0030] In the first step, when the user cools down and quickly freezes the steamed buns, the user opens the cabinet door 11, then pulls out the pulling frame 3, places the steamed buns on the pulling frame 3, then puts the pulling frame 3 back into the cooling box 15, closes the cooling cabinet 1, and starts the cooling machine 14. The cooling machine 14 is provided with a fan, and the fan transmits the air refrigerated by the cooling machine 14 downward, and the cold air settles downward. At the same time, the cold air enters the air port groove 16 along the second air guide plate 2, and then enters the cooling box 15 through the air port groove 16. The cold air contacts the steamed buns above the pulling frame 3, and the cold air is discharged from the air port groove 16 on the right side of the cooling box 15 along the pulling frame 3. In this way, the cold air circulates inside the cooling box 15, and the circulating air will be discharged through the exhaust port 12. By specially designing the inlet and outlet holes of the cooling box 15, it can be ensured that the steamed buns can be fully contacted by the cold air, thereby improving the cooling speed of the steamed buns.

[0031] In the second step, when the cold air sinks and contacts the first air guide plate 18, the cold air will sink along the two sides of the first air guide plate 18 and contact 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 and move 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 pulling frame 3 and then through the air outlet groove 16 on the right side of the cooling box 15. After flowing out, the cold air contacts 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, and 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 regulate the cold air, the contact time and area between the cold air and the steamed buns can be increased, thereby increasing the cooling speed of the steamed buns.

[0032] Since the inner wall of the cooling box 15 is a straight wall, the arc-shaped plate surface 23 is used to change the air flow direction, which can increase the speed of air flow at the corner and further improve the cooling cycle capacity.

[0033] In the third step, after the steamed buns are placed on the pulling frame 3, the bottom of the steamed buns contacts the multiple conical blocks 37. The multiple conical blocks 37 can prop up the steamed buns, so that a certain gap is formed between the steamed buns and the surface of the air inlet frame 32. When the cold air contacts the steamed buns, the cold air can contact not only the surface of the steamed buns but also the bottom of the steamed buns. The cold air circulates on both sides, thereby further improving the cooling speed of the steamed buns.

[0034] When the cold air circulates, it will enter the air intake frame 32 through the air intake pipe 35, and the cold air will enter the air flow channel 34. The cold air will flow in the air flow channel 34, and then flow upward through the exhaust net 38. The cold air passes through the exhaust net 38 and contacts the bottom of the steamed buns. The cold air will reduce the flow speed at the bottom of the steamed buns. At this time, the contact time between the cold air and the steamed buns can be increased, thereby increasing the cooling speed inside the steamed buns.

[0035] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
