Description

Technical Field

[0001] This utility model relates to the field of food production technology, and in particular to a cooling device for baked goods. Background Technology

[0002] As a popular food category, baked goods are increasingly valued for their quality, taste, and freshness as people's living standards improve and their consumption concepts change. After baking at high temperatures, baked goods are usually kept at a high temperature. If they are not cooled down in a timely and effective manner, it will not only affect their taste and quality but may also shorten their shelf life and even cause food safety issues.

[0003] Existing devices for cooling baked goods typically use fans to cool them down. They mainly achieve the purpose of cooling the baked goods by obtaining natural cooling from the outside. However, when the outside temperature is high or the natural cooling obtained by the fan is reduced, the cooling efficiency of the baked goods will decrease.

[0004] The existing patent (publication number: CN222634873U) discloses a cooling device for baked goods in food production, belonging to the field of food production technology. The key technical points of the device include a box body, with several partitions bolted inside the box body. A shell is bolted to the right side of the box body. An interception component and a compensation component are bolted to the two sides inside the shell body, respectively. An air intake fan is bolted to the right side of the shell body. The compensation component includes a first fixing frame, which is bolted to the left side inside the shell body. A coil is bolted to the front side inside the first fixing frame.

[0005] To address the aforementioned issues, existing patents have provided solutions, but these solutions suffer from the problem of not being able to cool the baked goods inside the cooling chamber evenly, resulting in cooling differences among the same batch of food. Additionally, existing cooling devices cannot ventilate the high-temperature gas inside the cooling chamber.

[0006] Therefore, a cooling device for baked goods is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a cooling device for baked goods, which can solve the problem that existing cooling devices for baked goods cannot cool the baked goods inside the cooling box evenly, resulting in cooling differences among the same batch of food. At the same time, existing cooling devices cannot ventilate the high-temperature gas inside the cooling box.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for baking food, comprising a cooling box, wherein two support frames are fixedly connected inside the cooling box, a cooling mechanism is provided inside the cooling box, and a ventilation treatment mechanism is provided in the middle of the cooling box.

[0009] The cooling mechanism includes a mounting frame disposed inside the cooling chamber, the mounting frame being located below the support frame, a plurality of cooling pipes being disposed in the middle of the mounting frame, a plurality of cooling holes being disposed at the top of the cooling pipes, a fan being bolted to the side wall of the cooling chamber, a connector being disposed at the output end of the fan, two diversion pipes being disposed on the side wall of the connector, a horizontal pipe being disposed at the other end of the diversion pipes, the horizontal pipes being connected and cooperating with the plurality of cooling pipes, and a cooling component being disposed inside the cooling pipes.

[0010] Preferably, the cooling assembly includes a cooling pipe disposed inside the cooling tube, with an inlet pipe and an outlet pipe respectively disposed at both ends of the cooling pipe, and a cooling connector disposed at the port of the inlet pipe and the outlet pipe respectively.

[0011] Preferably, the ventilation mechanism includes two ventilation pipes disposed in the middle of the cooling box, one end of each ventilation pipe is provided with a vertical pipe, an air extractor is bolted to the side wall of the cooling box, the input end of the air extractor is connected to the vertical pipe, a processing box is disposed at the bottom of the cooling box, and an air outlet pipe is disposed at the output end of the air extractor, the air outlet pipe extending to the bottom of the processing box.

[0012] Preferably, the top of the cooling tube is provided with multiple protective covers, which are located on top of the cooling holes and are inverted conical in shape.

[0013] Preferably, the cooling box has two flow guides fixedly connected inside, the flow guides are connected to the ventilation pipe, and the flow guides are located above the support frame.

[0014] Preferably, the air inlet end of the fan is provided with a dust cover, and the inside of the dust cover is provided with an air inlet filter.

[0015] Preferably, the interior of the horizontal tube is equipped with an ultraviolet disinfection lamp.

[0016] Preferably, a diverter plate is fixedly connected inside the connector, and the diverter plate is V-shaped.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application incorporates a cooling mechanism. This process involves setting multiple cooling tubes inside the cooling chamber, with multiple cooling holes at the top of each tube. This allows for the simultaneous release of a large amount of low-temperature cold air into the cooling chamber, increasing the contact area and contact opportunities between the cold air and the baked goods. This significantly improves heat exchange efficiency, thereby achieving efficient and rapid cooling of the baked goods. Simultaneously, the circulating flow of coolant within the cooling tubes continuously absorbs heat from the cooling tubes and the surrounding air, further reducing the temperature of the cold air and enhancing the cooling effect.

[0019] 2. This application incorporates a ventilation system. Through the coordinated operation of an exhaust fan, ventilation pipe, vertical pipe, and air guide hood, the hot air accumulated around the baked goods can be quickly extracted from the cooling chamber. The air guide hood effectively guides and concentrates the hot air, preventing localized accumulation within the cooling chamber. This allows the heat inside the cooling chamber to dissipate promptly, improving cooling efficiency and ensuring that the baked goods achieve the desired cooling effect in a shorter time, thus reducing the adverse effects of high temperatures on food quality.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 6 This utility model provides a technical solution:

[0031] A cooling device for baking food includes a cooling box 1, two support frames 2 are fixedly connected inside the cooling box 1, a cooling mechanism 3 is provided inside the cooling box 1, and an air exchange mechanism 4 is provided in the middle of the cooling box 1.

[0032] The cooling mechanism 3 includes a mounting frame 31 located inside the cooling box 1. The mounting frame 31 is located below the support frame 2. Multiple cooling pipes 32 are provided in the middle of the mounting frame 31. Multiple cooling holes 33 are provided at the top of the cooling pipes 32. A fan 34 is bolted to the side wall of the cooling box 1. A connector 35 is provided at the output end of the fan 34. Two diversion pipes 36 are provided on the side wall of the connector 35. A horizontal pipe 37 is provided at the other end of the diversion pipe 36. The horizontal pipe 37 is connected and cooperates with the multiple cooling pipes 32. A cooling component 38 is provided inside the cooling pipe 32.

[0033] Specifically, such as Figure 4 As shown, the cooling assembly 38 includes a cooling pipe 381 disposed inside the cooling pipe 32. The two ends of the cooling pipe 381 are respectively provided with an inlet pipe 382 and an outlet pipe 383, and a cooling connector 384 is respectively provided at the port of the inlet pipe 382 and the outlet pipe 383.

[0034] Specifically, such as Figure 3 As shown, the top of the cooling tube 32 is provided with multiple protective covers 6, which are located on top of the cooling hole 33 and are inverted conical in shape.

[0035] Specifically, such as Figure 3 As shown, the air inlet end of the fan 34 is equipped with a dust cover 8, and the inside of the dust cover 8 is equipped with an air inlet filter 9.

[0036] Specifically, such as Figure 3 As shown, an ultraviolet disinfection lamp 10 is installed inside the horizontal tube 37.

[0037] Specifically, such as Figure 3 As shown, a diverter plate 11 is fixedly connected inside the connector 35, and the diverter plate 11 is V-shaped.

[0038] In use, the external coolant supply system connects to the cooling connectors 384 at both ends of the cooling pipe 381, delivering low-temperature coolant from the inlet pipe 382 into the cooling pipe 381. The coolant flows within the cooling pipe 381. Because the coolant temperature is lower than the ambient temperature, it continuously absorbs heat from the cooling pipe 32 and the surrounding air, creating a low-temperature environment inside the cooling pipe 32. The coolant is then discharged through the outlet pipe 383, allowing for coolant circulation. The fan 34 draws in outside air through a dustproof cover and an air intake filter 9 at its air inlet. The air intake filter 9 filters the air. The air is cleaned by removing tiny particles, impurities, and some bacteria, ensuring that the air entering the fan 34 is relatively clean and preventing contamination of the subsequent cooling process and baked goods. The fan 34 compresses the intake air and outputs it from the output end. The air enters the connector 35, and the V-shaped splitter plate 11 evenly distributes the airflow into the two splitter pipes 36 on both sides, preventing eddies and congestion at the connector 35 and ensuring that the two splitter pipes 36 receive a stable and similar flow rate. The split airflow enters the two splitter pipes 36 respectively and then converges into the horizontal pipe 3. In section 7, the horizontal tube 37 is connected to multiple cooling tubes 32, and the airflow is further divided into each cooling tube 32. Since the cooling tubes 32 have cooling pipes 381 that continuously absorb heat, the airflow is rapidly cooled during its flow within the cooling tubes 32, forming a low-temperature cold airflow. The low-temperature cold airflow flows out from the cooling hole 33. The inverted conical structure of the protective cover 6 can guide and diffuse the cold airflow to a certain extent, allowing the cold airflow to be distributed more evenly and widely into the interior space of the cooling box 1. At the same time, the protective cover 6 can also prevent crumbs and other debris from falling directly into the cooling box. To prevent blockage of the cooling hole 33 and ensure smooth cooling, an ultraviolet disinfection lamp 10 is installed inside the horizontal tube 37. When the airflow passes through the horizontal tube 37, the ultraviolet light emitted by the ultraviolet disinfection lamp 10 will disinfect bacteria, viruses and other microorganisms in the airflow, reduce the content of microorganisms in the airflow, further ensure the hygiene and safety of baked goods during the cooling process, and reduce the risk of food spoilage due to microbial contamination. In this way, uniform cooling of baked goods inside the cooling box 1 is achieved, and the uniformity of cooling of baked goods is improved.

[0039] Specifically, such as Figure 6As shown, the ventilation treatment mechanism 4 includes two ventilation pipes 41 located in the middle of the cooling box 1. One end of each ventilation pipe 41 is provided with a vertical pipe 42. An air extractor 43 is bolted to the side wall of the cooling box 1. The input end of the air extractor 43 is connected to the vertical pipe 42. A treatment box 44 is provided at the bottom of the cooling box 1. An air outlet pipe 45 is provided at the output end of the air extractor 43. The air outlet pipe 45 extends to the bottom of the treatment box 44.

[0040] Specifically, such as Figure 6 As shown, two flow guides 7 are fixedly connected inside the cooling box 1. The flow guides 7 are connected to the ventilation pipe 41 and are located above the support frame 2.

[0041] During use, the heat emitted by baked goods, as well as any odors and moisture that may be generated, will accumulate inside the cooling chamber 1. After the exhaust fan 43 starts operating, it will create a negative pressure environment inside the cooling chamber 1, causing air to flow from the outside towards the exhaust fan 43. The guide shroud 7 is located above the support frame 2, allowing the guided and gathered airflow to smoothly enter the ventilation pipe 41. The airflow entering the ventilation pipe 41 flows along the ventilation pipe 41 to the vertical pipe 42 connected to one end. After the exhaust fan 43 pressurizes the intake airflow, it discharges the airflow through the exhaust pipe 45 at its output end. The exhaust pipe 45 extends to the bottom of the processing box 44 located at the bottom of the cooling chamber 1. The airflow enters the processing box 44 from the end of the exhaust pipe 45, and the processing box 44 performs heat exchange treatment on the high-temperature gas.

[0042] By adopting the above technical solution, the problem that existing baking food cooling devices cannot uniformly cool the baking food inside the cooling box 1 is solved, resulting in cooling differences among the same batch of food. At the same time, the existing cooling devices cannot exchange the high-temperature gas inside the cooling box 1.

[0043] Working Principle: In use, the external coolant supply system connects to the cooling connectors 384 at both ends of the cooling pipe 381, supplying low-temperature coolant from the inlet pipe 382 into the cooling pipe 381. The coolant flows within the cooling pipe 381. Because the coolant temperature is lower than the ambient temperature, it continuously absorbs heat from the cooling pipe 32 and the surrounding air, creating a low-temperature environment inside the cooling pipe 32. The coolant is then discharged through the outlet pipe 383, allowing for coolant circulation. The fan 34 compresses the intake air and outputs it from the outlet. The air enters the connector 35, and the V-shaped splitter plate 11 evenly distributes the airflow into the splitter pipes 36 on both sides. The horizontal pipe 37 connects to multiple cooling pipes 32, further splitting the airflow. Entering each cooling pipe 32, the low-temperature cold air flows out from the cooling hole 33, uniformly cooling the food inside the cooling box 1. At the same time, the vacuum pump 43 creates a negative pressure environment inside the cooling box 1, causing air to flow from the outside towards the vacuum pump 43. The guide shroud 7 is located above the support frame 2, allowing the guided and gathered airflow to smoothly enter the ventilation pipe 41. The airflow entering the ventilation pipe 41 flows along the ventilation pipe 41 to the vertical pipe 42 connected to one end. After the vacuum pump 43 pressurizes the intake airflow, it discharges the airflow through the outlet pipe 45 set at its output end. The outlet pipe 45 extends to the bottom of the processing box 44 set at the bottom of the cooling box 1. The airflow enters the processing box 44 from the end of the outlet pipe 45, and the processing box 44 performs heat exchange treatment on the high-temperature gas.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
