Description

Technical Field

[0001] The utility model belongs to the technical field of food processing equipment, and in particular relates to a steamed bun cooling device. Background Art

[0002] Instant steamed dumplings refer to dumplings that are pre-wrapped and steamed, then quickly frozen at low temperatures, and then packaged and sold. They are one of the quick-frozen foods. The dumplings need to be cooled after steaming and before quick-freezing, otherwise the skin of the dumplings will collapse and the quality will be affected. Cooling equipment is used to cool the dumplings. Existing cooling equipment generally places the dumplings in a cooling box, and then sprays atomized pure water into the cooling box to absorb the heat of the dumplings, so as to achieve the purpose of cooling the dumplings. In this way, during the cooling process of the dumplings, it is necessary to continuously spray water into the cooling box to improve the cooling efficiency. Therefore, water will adhere to the skin of the dumplings. If the water is not released in time, the dumplings will have rotten skin and collapsed skin, affecting the quality of the dumplings. In addition, it will also cause ice chips to appear on the surface of the dumplings after subsequent quick freezing.

[0018] The following are examples and the attached Figure 1-Figure 4The structure is shown in the figure, and the technical solution of the utility model is further specifically described.

[0019] Embodiment: A steamed dumpling cooling device comprises a mounting frame 1, on which a mesh-type conveyor belt 2 is provided, a cooling box 3 is fixed on the top of the mounting frame 1, and five exhaust fans 4 are arranged in a row on the top of the cooling box 3, and an air collecting hood 5 is fixed on the top of the cooling box 3 and located outside the exhaust fans 4, the air collecting hood 5 is connected to an exhaust duct 6, and the other end of the exhaust duct 6 is connected to a three-way interface 13, and air outlet boxes 7 are symmetrically fixed on both sides of one end of the top of the mounting frame 1, and two of the air outlet boxes 7 are connected to an air inlet duct 9 connected to the exhaust duct 6, and the two air inlet ducts 9 are connected to the three-way interface 13, and the opposite sides of the two air outlet boxes 7 are vertically arrayed with a plurality of downwardly inclined air guide plates 8, such as Figure 2 As shown, after the exhaust fan 4 draws the air out of the cooling box 3 and sends it into the two air outlet boxes 7 through the air inlet pipe 9, the air guide plate 8 can blow the wind downward to the surface of the dumplings placed on the conveyor belt 2 to pre-cool the dumplings, thereby avoiding the large temperature change after the dumplings enter the cooling box 3, which may cause the skin of the dumplings to collapse. A rectangular groove is provided at the bottom of the mounting frame 1, and a water collecting bucket 10 is fixed at the bottom of the mounting frame 1 and located on the rectangular groove. A drain port 15 is provided at the bottom of the water collecting bucket 10, and one side of the water collecting bucket 10 is connected to an air inlet pipe 12 for the entry of cold air. A guide plate 11 is fixed on the top of the water collecting bucket 10, and the guide plate 11 is inclined from high to low from the middle to the two sides. The specific shape is as shown in the figure. Figure 3 and Figure 4 As shown, the guide plate 11 is provided with guide holes 14 in a rectangular array.

[0020] The inner top wall of the cooling box 3 is an arc-shaped concave surface protruding upward, and the inner bottom wall of the mounting frame 1 and the part located in the cooling box 3 are inclined from high to low from both sides to the middle, so that when the dumplings are cooled, the heat in the dumplings is condensed into condensed water on the inner top wall of the cooling box 3 when it encounters cold, and then slides along the arc-shaped concave surface to the two side walls of the cooling box 3, and then flows along the side walls to the inner bottom wall of the mounting frame 1, and finally flows along the inner bottom wall of the mounting frame 1 to the rectangular groove, and finally flows into the water collecting bucket 10 and is discharged through the drain port 15, thereby avoiding the problem of condensed water dripping on the surface of the dumplings, causing the dumplings to rot and the skin to collapse.

[0021] The working principle of this utility model:

[0022] When in use, the utility model is connected to an external refrigeration device through an air inlet pipe 12, and cold air is first delivered to the water collecting bucket 10 through the external refrigeration device, and the exhaust fan 4 is turned on to extract the air in the cooling box 3 to form a local negative pressure, thereby guiding the cold air to rise to pre-cool the cooling box 3. After the cooling box 3 is pre-cooled, the conveyor belt 2 is started, and the tray with the steamed buns is placed on the conveyor belt 2. The air delivered by the exhaust fan 4 passes through the exhaust pipe 6 and the two air inlet pipes 9 and is blown out from the two air outlet boxes 7 obliquely downward to pre-cool the steamed buns, and then the steamed buns are transported by the conveyor belt 2 into the cooling box 3. The cooled steamed buns are sent out of the cooling box 3 by a conveyor belt to be collected by an operator or the device is connected to a quick-freezing device, and the cooled steamed buns are directly sent into the quick-freezing device for quick freezing. The heat emitted by the steamed buns during the cooling process will condense into condensed water on the top of the cooling box 3 after encountering the cold air in the cooling box 3. The condensed water slides along the inner top wall of the cooling box 3 to the side wall of the cooling box 3 and then flows downward to the inner bottom wall of the mounting frame 1 and finally flows into the water collecting bucket 10 and is discharged through the drain port 15, thereby preventing the condensed water from dripping on the surface of the steamed buns and affecting the quality of the steamed buns.

[0023] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
