Description

Technical Field

[0001] The invention relates to the technical field of article cooling, in particular to a spiral cooling tower used for refrigerating articles. Background Art

[0002] At present, after the baked product is taken out of the oven, the evaporation process in the baked product has not yet ended. Depending on the type, size and shape of the baked product, this process will continue for several hours, so the baked product needs to be cooled. This process is usually carried out using a spiral cooling tower, which can effectively reduce the cooling time of the product and improve production efficiency. However, during the use of the current spiral cooling tower, the cold air will heat up after contacting the baked product, resulting in the cold air flowing through the product on the left spiral cooling tower flowing to the right side of the spiral cooling tower. The temperature has changed and is mixed with moisture, resulting in some products being overcooled or overheated, causing product deformation, wrinkled skin or other quality problems; For example, a spiral cooling tower disclosed in the publication number CN214620275U can drive the transmission chain to drive the inner rotating frame to rotate stably through a rotating drive device, and reduce the friction during the rotation process, simplify the transmission structure of the inner rotating frame, and improve the overall transmission efficiency of the inner rotating frame. However, when the cold air is blown onto the baked products placed thereon, the cold air directly passes through the spiral cooling tower and blows onto the products on both sides. The temperature of the cold air blown to the products on both sides is different, causing some products to deform, wrinkle or have other quality problems. The publication number is CN217686. The spiral pasta cooling tower disclosed in 042U can generate reverse counter-flow airflows by the reverse rotation between the first rotating plate and the second rotating plate, so that the counter-flow airflows flow in a horizontal 360° direction after impact, so as to achieve 360° horizontal stable blowing and heat dissipation of the pasta on the spiral rack. However, after the airflow contacts the baked product, the mixed moisture still remains in the cold air, and only the side of the product on the spiral rack close to the inner circle can be cooled, and the side of the outer circle cannot be cooled, resulting in uneven cooling of some products, causing deformation, wrinkling of the skin or other quality problems; Therefore, a spiral cooling tower for refrigerating articles is proposed.

[0010] The present invention provides a spiral cooling tower for refrigerating articles. Compared with the prior art, the spiral cooling tower has the following beneficial effects: (1) The spiral cooling tower used for refrigerating items can ensure that the cold air evenly covers the surface of all baked products by precisely controlling the flow direction of the cold air, thereby accelerating the speed of heat transfer from the product to the surrounding environment. This not only improves the cooling efficiency, but also shortens the cooling time, thereby improving the cooling efficiency. Reasonable diversion design helps to avoid the problem of overcooling or overheating in certain areas, ensuring that every part of the product can get a consistent cooling effect, maintaining product quality, helping to maintain the best texture, color and taste of baked goods, and preventing product deformation, wrinkling of the skin or other quality problems caused by improper cooling. The cold air diversion direction can be adjusted according to different types of baked products, so that the same set of equipment can flexibly respond to the cooling needs of various products, increasing production flexibility.

[0011] (2) The spiral cooling tower used for refrigerating goods can dynamically adjust the cold air supply of each zone to ensure that the products in each zone can obtain the appropriate cooling speed and effect, thereby further reducing product quality problems caused by uneven cooling, such as texture changes and deformation caused by local overheating or overcooling. At the same time, it can better adapt to the needs of products of different types or sizes, and can achieve the ideal cooling effect without frequent adjustments to equipment settings. It improves the flexibility and adaptability of the production line, provides only the right amount of cooling capacity where it is needed, avoids energy waste caused by excessive cooling, and helps reduce overall energy consumption and operating costs.

[0012] (3) The spiral cooling tower used for refrigerating items can maximize the use of cooling resources by recycling the cold air flow. The cold air flow first cools one side and then cools the other side after processing. This ensures that each product surface is fully cooled, improves the overall cooling efficiency, and helps to further achieve a more uniform cooling effect, because both sides of each product can be cooled under the same conditions, reducing the temperature difference caused by unilateral cooling and ensuring the consistency of product quality.

[0013] (4) The spiral cooling tower used for refrigerating items can flexibly adjust the cooling parameters according to the characteristics and cooling requirements of different baked products by adjusting the air volume and wind direction. Accurately controlling the direction and intensity of the cold air flow can help overcome the problem of cooling dead corners caused by irregular product shapes or placement positions, so that each product can be cooled evenly and effectively to avoid local overheating or overcooling. Different baked products have different optimal cooling conditions. By setting up an auxiliary mechanism with adjustable functions, the production line can be quickly switched to a cooling mode suitable for different types of products, thereby improving the versatility and adaptability of the production line.

[0014] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In the embodiments of the present application, the devices or elements referred to or implied must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise precisely and specifically specified.

[0019] See also Figures 1 to 3 , Figures 5 to 8 , Embodiment 1: A spiral cooling tower for refrigerating goods, comprising a cooling room 1 forming a closed cooling space, a cooling unit 11 located at the top of the cooling room 1 for refrigeration, a feeding unit 12, a discharging unit 13 and a screw conveyor 14 located in the cooling room 1 for conveying products to be cooled, a flow guide assembly for guiding the flow of cold air is arranged in the cooling room 1, and the flow guide assembly comprises: a power motor 2, an output shaft 21, a power gear 22, a driven gear 23, a rotating shaft 24, a support rod 25, a flow guide plate 26, a guide rod 27, and a flow guide cover 28; The bottom of the power motor 2 is fixedly mounted on the bottom of the inner wall of the cooling room 1 through a motor box, and the power motor 2 is used to drive the guide plate 26 to change its position; One end of the output shaft 21 is fixedly mounted on the output end of the power motor 2 through a coupling, and the output shaft 21 is used to transmit the power output by the power motor 2; The bottom of the power gear 22 is fixedly mounted on the end of the output shaft 21 away from the power motor 2; The driven gear 23 is meshedly connected with the power gear 22, and the driven gear 23 is used to change the rotation speed while transmitting the power required for the operation of the guide assembly; One end of the rotating shaft 24 is movably mounted on the bottom of the inner wall of the cooling room 1 through shaft gears, and the side wall of the rotating shaft 24 is fixedly connected to the other end of the support rod 25. The rotating shaft 24 is used to provide support for the support rod 25. One end of the rotating shaft 24 is fixedly penetrated in the driven gear 23, and the rotating shaft 24 provides support for the driven gear 23. One end of the support rod 25 is fixedly mounted on the guide plate 26. The support rod 25 provides support for the guide plate 26 and drives the guide plate 26 to rotate under the drive of the power motor 2. The guide plate 26 is slidably mounted on the guide cover 28 to deliver cold air to the product; One end of the guide rod 27 is fixedly mounted on the bottom of the guide plate 26, and the other end of the guide rod 27 is slidably inserted into the guide cover 28. The guide rod 27 is used to limit the moving direction of the guide plate 26. The guide hood 28 is located directly below the cooling unit 11 and at the center of the screw conveyor 14 to guide the cold air flow to cool the product.

[0020] When in use, the control center controls the cooling unit 11 to operate, so that the cooling unit 11 conveys cold air to the screw conveyor 14 in the cooling room 1, and then the control center controls the feeding unit 12 to convey the baked products to be cooled, such as bread, hamburgers, toast, cakes, moon cakes, etc., to the screw conveyor 14 in the cooling room 1, so that the screw conveyor 14 drives these baked products to spirally move in the cooling room 1 and cool them until they are conveyed to the discharging unit 13, and then conveyed to the outside of the cooling room 1 through the discharging unit 13; In the process of cooling these baked products for refrigeration, the cold air blown out by the cooling unit 11 is drained through the drainage cover 28, and the power motor 2 is started by the control center, and the power motor 2 drives the output shaft 21 to rotate, the output shaft 21 drives the power gear 22 to rotate, the power gear 22 drives the driven gear 23 to rotate, the driven gear 23 drives the rotating shaft 24 to rotate, the rotating shaft 24 drives the support rod 25 to rotate, and the support rod 25 drives the guide plate 26 to rotate; Eighty percent of the cold air delivered by the cooling unit 11 is directed downward through the drainage cover 28. During the process, the rotating guide plate 26 will deliver the cold air from the drainage cover 28 to the screw conveyor 14, so that the cold air can fully cool one half of the baked products on the screw conveyor 14. Then, the remaining cold air fully cools the other half of the baked products on the screw conveyor 14 from the outside of the drainage cover 28, so that the baked products can be quickly and fully cooled and then delivered to the outside of the cooling room 1 by the discharging unit 13; During the rotation of the guide plate 26, the guide plate 26 drives the guide rod 27 to rotate synchronously, and the guide rod 27 is slidably adapted to the guide cover 28, so that the guide rod 27 can make a circular motion along the guide cover 28, thereby supporting and limiting the guide plate 26, so that the guide plate 26 can also make a circular motion along the guide cover 28, and the rotation direction is opposite to the feeding direction of the screw conveyor 14, so that the cold air flow can quickly flow away from the baked products, perform heat exchange, and thus take away the heat from the baked products.

[0021] See also Fig. 9 , Fig.10 The present invention provides a second embodiment, which is different from the first embodiment in that the technical solution includes: The cooling room 1 is provided with an enhancement component for changing the air volume of the guide component, and the enhancement component includes: a sliding column 3, an electromagnet 31, a magnet 32, an expansion plate 33, a spring 34, and a compensation plate 35; One end of the sliding column 3 is fixedly mounted on the inner wall of the guide plate 26; The electromagnet 31 is fixedly mounted on the sliding column 3; The magnet 32 ​​is slidably disposed on the sliding column 3, and the magnet 32 ​​and the electromagnet 31 are magnetically matched, and the magnet 32 ​​and the electromagnet 31 are matched to change the position of the expansion plate 33; One end of the spring 34 is fixedly mounted on the expansion plate 33, and the other end of the spring 34 is fixedly mounted on the inner wall of the guide plate 26. The spring 34 is used to apply a resetting elastic force to the expansion plate 33; One end of the compensation plate 35 is slidably abutted against the expansion plate 33, and the outer wall of the other side of the compensation plate 35 is hinged to the outer wall of the guide plate 26 through a torsion spring. The compensation plate 35 is used to reduce the air volume loss; The expansion plate 33 is slidably mounted in the guide plate 26 to change the flow rate of cold air received by the product.

[0022] When in use, the internal space of the cooling room 1 is divided into zones, and the temperature is monitored in each zone occupied by the screw conveyor 14; When switching to a different baked product or the cooling of the current product is uneven, the control center starts the enhancement component, and the electromagnet 31 is energized to make the magnetism between the electromagnet 31 and the magnet 32 ​​repel each other. The magnet 32 ​​can move to the side away from the electromagnet 31 through the repulsive force. At the same time, the magnet 32 ​​is slidably adapted to the sliding column 3, so that the magnet 32 ​​can only move in a straight line along the sliding column 3 when moving. By changing the repulsive force between the electromagnet 31 and the magnet 32, the distance that the magnet 32 ​​moves along the sliding column 3 is controlled. The magnet 32 ​​drives the expansion plate 33 to move synchronously, and the expansion plate 33 moves out from the guide plate 26, so that more cold air can be drawn out from the guide cover 28 at the guide plate 26 of this layer. At the same time, the expansion plate 33 squeezes the compensation plate 35 during the moving process, so that the compensation plate 35 turns outward with the torsion spring as the axis, so as to prevent the airflow from flowing from between the expansion plate 33 and the guide plate 26 to other places, thereby reducing the airflow loss; At the same time, the spring 34 applies a pulling force to the expansion plate 33 on the side where the guide plate 26 is located, so that when the magnetism between the electromagnet 31 and the magnet 32 ​​disappears or weakens, the expansion plate 33 can be retracted into the guide plate 26 under the action of the spring 34.

[0023] See also Figure 4 , Fig.11 The present invention provides a third embodiment, which is different from the second embodiment in that the technical solution includes: A reflux assembly for changing the cooling area of ​​the product is provided in the cooling room 1, and the reflux assembly includes: a driving gear 4, a transmission gear 41, a transmission shaft 1 42, a driven gear 43, a transmission shaft 2 44, a support plate 45, an air induction plate 46, an air breaking plate 47, a contact plate 48, a scraper 49, and an air collecting plate 410; The driving gear 4 is meshed with the transmission gear 41, and the driving gear 4 is fixedly mounted on the rotating shaft 24; One end of the transmission shaft 42 is movably mounted on the bottom of the inner wall of the cooling room 1 through a bearing, and the other end of the transmission shaft 42 is fixedly mounted on the bottom of the transmission gear 41; The driven gear 43 is meshedly connected with the transmission gear 41; The bottom of the second transmission shaft 44 is movably mounted on the bottom of the inner wall of the cooling room 1 through a bearing, and the other end of the second transmission shaft 44 is fixedly mounted on the bottom of the passive gear 43; One end of the support plate 45 is fixedly mounted on the side wall of the second transmission shaft 44; The air guide plate 46 is located outside the screw conveyor 14 and is provided with openings on both sides to process and guide the air blown out by the guide plate 26; Both ends of the wind-breaking plate 47 are fixedly mounted at one side opening of the wind-inducing plate 46, and the wind-breaking plate 47 changes the flow direction of the gas entering the wind-inducing plate 46; One end of the contact plate 48 is fixedly mounted inside the air induction plate 46, and a protrusion is provided on the surface of the contact plate 48, and the contact plate 48 is used to increase the contact area with the airflow; The side wall of the scraper 49 is slidably mounted on the support plate 45, and the scraper 49 is used to collect the water vapor in the air induction plate 46; The outer wall of the air collecting plate 410 is fixedly installed at the opening on the other side of the air inducing plate 46, and the air collecting plate 410 is used to change the flow direction of the airflow.

[0024] When in use, while the power motor 2 drives the rotating shaft 24 to rotate through the output shaft 21, the power gear 22, and the driven gear 23, the rotating shaft 24 synchronously drives the driving gear 4 to rotate, and the driving gear 4 drives the transmission gear 41 to rotate, and the transmission shaft 1 42 provides a supporting force for the transmission gear 41, and the transmission gear 41 drives the driven gear 43 to rotate, and the transmission shaft 2 44 provides a supporting force for the driven gear 43, and the driven gear 43 drives the transmission shaft 2 44 to rotate synchronously, and the support plate 45 is driven to rotate through the transmission shaft 2 44, and the support plate 45 drives the scraper 49 to rotate synchronously; The fixed plate of the screw conveyor 14 provides support for the air induction plate 46, and the air induction plate 46 provides support for the air breaking plate 47. At the same time, the air breaking plate 47 guides the cold and warm air flows mixed with the heat of the baked products to flow toward the middle and lower part of the air induction plate 46. This part of the air flow will blow on the contact plate 48, and the contact area with the cold and warm air flows will be increased through the contact plate 48, so that the warm air flow in it contacts the contact plate 48 with a lower temperature, so that the water vapor in the cold and warm air flows condenses on the surface of the contact plate 48, and finally drips to the bottom of the inner wall of the air induction plate 46. After the support plate 45 drives the scraper 49 to rotate, the scraper 49 can gather the water vapor in the bottom of the inner wall of the air induction plate 46 into water droplets and then scrape them to one place, and a water flow hole can be opened at the bottom of the inner wall of the air induction plate 46 to make the water droplets flow to the outside of the cooling room 1 through the water flow hole and the water flow pipe; The driven gear 43 is a half gear. When the driven gear 43 and the transmission gear 41 are not in meshing state, the transmission shaft 44 is reset with itself as the axis under the action of the spiral spring, so that the scraper 49 is reset from one end of the air induction plate 46 to the other end, and the water droplets collected in the air induction plate 46 are fully discharged by the scraper 49 scraping back and forth; At the same time, the cold air flow that has lost its water vapor and cooled down after condensation flows back to the baked products on the screw conveyor 14 through the air collecting plate 410, thereby cooling down the other side of the baked products.

[0025] See also Fig.12 , Fig.13 , the embodiment of the present invention also provides another embodiment different from the above-mentioned embodiment, in which the scraper 49 is no longer directly fixed on the support plate 45; The reflux assembly also includes an auxiliary mechanism for changing the direction of the airflow, which includes: electromagnet 2 5, magnetic ring 51, adjustment plate 52, fixing rod 53, mounting plate 54, mounting shaft 55, telescopic rod 1 56, telescopic rod 2 57, and connecting ring 58. One end of the electromagnet 2 5 is fixedly mounted on the support plate 45; Magnetic coordination between the magnetic ring 51 and the electromagnet 2 5; The side wall of the adjustment plate 52 is fixedly connected to the side wall of the magnetic ring 51, and the side wall is hinged to one end of the wind collecting plate 410 through a hinge. The adjustment plate 52 provides support for the magnetic ring 51, and the adjustment plate 52 can change its angle under the drive of the magnetic ring 51; The auxiliary mechanism also includes: a fixed rod 53, a mounting plate 54, a mounting shaft 55, a telescopic rod 1 56, and a telescopic rod 2 57; One end of the fixing rod 53 is fixedly mounted on one end of the mounting plate 54 away from the mounting shaft 55; The mounting plate 54 is fixed on the mounting shaft 55; Both ends of the mounting shaft 55 are movably mounted in the support plate 45 through bearings, and the support plate 45 is provided with mounting holes that match the movable path of the mounting plate 54; One end of the telescopic rod 56 is fixedly mounted on the end of the fixed rod 53 away from the mounting plate 54; One end of the telescopic rod 2 57 is slidably inserted into the telescopic rod 1 56 , and the other end of the telescopic rod 2 57 is fixedly mounted on the scraper 49 .

[0026] When in use, when switching to a different baked product or the cooling of the current product is uneven, the control center controls the auxiliary mechanism to start, thereby energizing the electromagnet 2 5, so that the magnetic relationship between the electromagnet 2 5 and the magnetic ring 51 is changed, and the electromagnet 2 5 magnetically attracts or repels the magnetic ring 51, so that the magnetic ring 51 can drive the adjustment plate 52 to flip around the hinge as the axis, and at the same time, one end of the adjustment plate 52 will slide and abut against the fixed rod 53 or the end of the scraper 49 close to the fixed rod 53; When the adjustment plate 52 flips toward the side close to the scraper 49 under the action of magnetic force, the fixing rod 53 is provided with supporting force through the mounting plate 54, and the fixing rod 53 provides supporting force to the mounting shaft 55, and the supporting plate 45 provides supporting force to the mounting shaft 55, so that the fixing rod 53 and the mounting plate 54 flip around the mounting shaft 55 as the axis, and at the same time, the telescopic rod 1 56 and the telescopic rod 2 57 are separated from each other, so that the flow direction of the cold air flowing out through the air collecting plate 410 can be changed. At the same time, since the distance between the air collecting plate 410 and the adjustment plate 52 is reduced, the air volume is reduced to a certain extent, so that the wind direction and flow rate can be changed according to the cooling conditions of different products; When the adjustment plate 52 flips to the side away from the scraper 49 under the action of magnetic force, the mounting plate 54 and the fixing rod 53 can also flip with the mounting shaft 55 as the axis. At the same time, the telescopic rod 1 56 and the telescopic rod 2 57 are close to each other, so that the flow direction of the cold air flowing out through the air collecting plate 410 can be changed. At the same time, due to the increase in the distance between the air collecting plate 410 and the adjustment plate 52, the air output and flow rate are increased to a certain extent.

[0027] In another embodiment different from the aforementioned embodiment, the contact plate 48 is changed into a porous material plate, and the temperature of the porous material plate is maintained at a low temperature. At the same time, a knocking component is arranged on the surface of the porous material plate so that the knocking component can shake off the condensed water vapor in the porous material plate and collect the water vapor in the air induced plate 46.

[0028] In summary, the technical solution disclosed in the above-mentioned embodiments of the present invention has at least the following advantages: by precisely controlling the flow direction of cold air, it is ensured that the cold air evenly covers the surface of all baked products, thereby accelerating the speed of heat transfer from the product to the surrounding environment, which not only improves the cooling efficiency, but also shortens the cooling time, thereby improving the cooling efficiency. Reasonable diversion design helps to avoid the problem of overcooling or overheating in certain areas, ensures that each part of the product can obtain a consistent cooling effect, maintains product quality, helps to maintain the best texture, color and taste of baked food, prevents product deformation, wrinkling of the skin or other quality problems caused by improper cooling, and can adjust the cold air diversion direction according to different types of baked products, so that the same set of equipment can flexibly respond to the cooling needs of various products, increasing production flexibility; By dynamically adjusting the cold air supply to each zone, it is ensured that the products in each area can obtain the appropriate cooling speed and effect, thereby further reducing product quality problems caused by uneven cooling.
