[0003] As a key device, the food quick-freezing air cooler can quickly lower the temperature of food and achieve the freezing effect of food. Its working principle is usually to spray the cooling air flow directly onto the surface of the food, and use conduction and convection to quickly take away the heat from the food, so that the food can be quickly cooled and frozen. This technology can effectively retain the nutritional content and taste of the food while extending the shelf life of the food. The existing quick-freezing device sprays cold air onto the surface of the food, but the cold air continuously blows from one direction of the food to the food, causing a single direction of the food to be frozen, which in turn causes the freezing rate of different positions of the food to be inconsistent, and the food has the problem of uneven freezing.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Embodiment 1:

[0036] Reference Figure 1-11 A food quick-freezing air cooler, comprising a channel 1 with openings at both ends, a refrigeration device 2 installed on the channel 1, a conveying mechanism 3 for driving food to move installed in the channel 1, an air pump 4 fixedly installed on the channel 1, an air inlet pipe of the air pump 4 is connected to the cold air of the refrigeration device 2, an air cavity 5 is provided in the channel 1, a pipe 6 is connected and fixedly connected to the air cavity 5, an exhaust pipe of the air pump 4 is connected and fixedly connected to the pipe 6, an upper end of the pipe 6 is open and a sealing plug 7 is provided in the open end;

[0037] The air cavity 5 is arranged at the upper end of the conveying mechanism 3, and a plurality of evenly distributed air outlets 8 are provided at the bottom of the air cavity 5. A plurality of evenly distributed extension tubes 9 are penetrated on both sides of the bottom of the air cavity 5, and a plurality of evenly distributed exhaust holes 10 are provided on the opposite sides of the extension tubes 9 on both sides. The exhaust holes 10 at the upper end are connected with the air cavity 5, and a connecting piece 11 is provided above the air cavity 5. The connecting piece 11 is fixedly connected to the plurality of extension tubes 9 and the sealing plug 7, and a plurality of springs 12 are fixedly connected to the connecting piece 11, and the lower ends of the springs 12 are all fixedly connected to the air cavity 5.

[0038] The refrigeration device 2 and the air pump 4 work, and the air pump 4 guides the cold air into the pipe 6, enters the air cavity 5 through the pipe 6, and then is discharged into the channel 1 through the multiple exhaust holes 10.

[0039] Among them, the conveying mechanism 3 includes a plurality of rollers 13 located in the channel 1 and distributed equidistantly, the rollers 13 are rotatably mounted on the channel 1, a first synchronous belt mechanism 14 is installed between adjacent rollers 13, and adjacent rollers 13 are driven by the first synchronous belt mechanism 14, a driven wheel 15 is fixedly mounted on the rotating shaft of the roller 13 located on one side, a first motor 16 is fixedly mounted on the channel 1, a driving wheel 17 is fixedly mounted on the output shaft end of the first motor 16, and the driving wheel 17 is meshed with the driven wheel 15. The conveying mechanism 3 also includes a plurality of center rollers 18, which are respectively arranged between adjacent rotating rollers 13. The center rollers 18 are rotatably installed in the channel 1. A second belt mechanism 19 is installed between adjacent center rollers 18. The adjacent center rollers 18 are driven by the second belt mechanism 19. A first gear 20 is fixedly installed on the rotating shaft of the center roller 18 located on one side, a second motor 21 is fixedly installed on the channel 1, and a second gear 38 is fixedly installed on the output shaft end of the second motor 21, and the second gear 38 is meshed with the first gear 20.

[0040] The first motor 16 drives the driving wheel 17 to rotate, and the driving wheel 17 drives the driven wheel 15 to rotate, which can drive the rotating shaft of the roller 13 on one side to rotate. The roller 13 on one side rotates and is transmitted to the adjacent roller 13 through the first synchronous belt mechanism 14, which can drive multiple rollers 13 to rotate synchronously in the same direction. The food is placed on the roller 13 on one side, and the food can be driven to move to one side in the channel 1 through the multiple rotating rollers 13. The multiple exhaust holes 10 discharge cold air, and the cold air blows to the upper side of the food. During the movement of the food, the food is continuously cooled by the cold air, thereby realizing the quick freezing of the food. At the same time, the food can be continuously placed on the roller 13 on one side, and a large number of foods can be quickly frozen.

[0041] By providing the extension tube 9 and the exhaust hole 10, the extension tube 9 is connected with the air cavity 5, and the cold air in the air cavity 5 can enter the multiple extension tubes 9, and then be discharged from the exhaust hole 10 on the side of the extension tube 9, so that the cold air is blown to both sides of the food, thereby improving the freezing efficiency of the two sides of the food, which not only improves the freezing rate of the food, but also makes the temperature of the food more uniform.

[0042] The second motor 21 drives the second gear 38 to rotate, and the second gear 38 drives the first gear 20 to rotate. The first gear 20 rotates synchronously with the rotating shaft of the middle roller 18 on one side. The middle roller 18 on one side drives the adjacent middle roller 18 to rotate through the second belt mechanism 19, thereby driving multiple middle rollers 18 to rotate synchronously, and the middle roller 18 and the rotating roller 13 turn in the same direction, so that the food on the rotating roller 13 can move more smoothly.

[0043] A guide plate 22 is provided between the center roller 18 and the adjacent rotating roller 13. The guide plate 22 is fixedly connected to the lower end of the extension tube 9. The sealing plug 7 is made of magnet material. An electromagnet 23 is fixedly installed in the channel 1. The electromagnet 23 is set toward the sealing plug 7. When the electromagnet 23 is energized, a repulsive force can be applied to the sealing plug 7.

[0044] The food is then guided by a plurality of guide plates 22 to further improve the smoothness of the food moving in the channel 1. Since the outer surfaces of the rotating roller 13 and the middle roller 18 are in direct contact with the food, the outer surfaces of the rotating roller 13 and the middle roller 18 are easily adhered to food, dust or other pollutants. The pollutants on the rotating roller 13 and the middle roller 18 need to be cleaned in time. If not, the pollutants will adhere to the roller surface more firmly, making it difficult to clean the rotating roller 13 and the middle roller 18.

[0045] When the food freezing work is suspended, the electromagnet 23 is energized so that the electromagnet 23 exerts a repulsive force on the sealing plug 7, so that the sealing plug 7 moves downward and blocks the connecting port between the pipeline 6 and the exhaust pipe of the air pump 4, thereby isolating the air cavity 5 from the outside world, avoiding heat exchange between the higher temperature air outside and the lower temperature air in the channel 1, and the channel 1 is in a heat-insulating state.

[0046] At the same time, the sealing plug 7, the connecting piece 11, the extension tube 9 and the guide plate 22 move synchronously, so that the guide plate 22 moves downward, the multiple springs 12 are compressed, and the bottom ends of the guide plate 22 contact the adjacent rollers 13 and the middle roller 18, and then drive the multiple rollers 13 and the middle roller 18 to rotate. There is an extrusion force between the guide plate 22 and the rollers 13 and the middle roller 18. The guide plate 22 can scrape off the pollutants adhering to the surface of the rollers 13 and the middle roller 18, and can clean the pollutants on the rollers 13 and the middle roller 18 in time to avoid the pollutants remaining for a long time and adhering to the roller surface more firmly. The cleaning method is convenient and the cleaning range covers the roller surface, and the cleaning effect is good. After the cleaning is completed, the electromagnet 23 is powered off, and the elastic force of the multiple springs 12 drives the sealing plug 7, the connecting piece 11, the extension tube 9 and the guide plate 22 to reset.

[0047] Embodiment 2:

[0048] Reference Figure 1-12As another preferred embodiment of the present invention, the difference from Embodiment 1 lies in that the interiors of the rotating roller 13 and the middle roller 18 are hollow, the interiors of the rotating shafts at both ends of the rotating roller 13 and the middle roller 18 are hollow, the rotating roller 13 and the middle roller 18 are connected with the rotating shafts thereon, a plurality of evenly distributed air grooves 24 are provided on the rotating roller 13 and the middle roller 18, the rotating roller 13 and the middle roller 18 are connected with the outside through the air grooves 24, a plurality of evenly distributed strip grooves 25 are provided on the guide plate 22, the strip grooves 25 penetrate the guide plate 22, a plurality of air ducts 26 are connected and fixedly installed on the air cavity 5, the other end of the air duct 26 is rotatably installed on the rotating shaft of the rotating roller 13, and the air duct 26 is connected with the rotating shaft of the rotating roller 13.

[0049] Among them, two first blocking parts 27 are provided between adjacent rollers 13, and the two first blocking parts 27 are located at both ends of the rollers 13. The first blocking parts 27 can block the area between the two adjacent rollers 13 and the center roller 18. The first blocking parts 27 are fixedly connected to the inner wall of the channel 1, and the rotating shaft of the center roller 18 passes through the first blocking parts 27.

[0050] Among them, a second blocking member 28 is arranged in the channel 1, and the second blocking member 28 is located at the lower ends of multiple rollers 13. The second blocking member 28 can block the air permeable grooves 24 in the lower half areas of multiple rollers 13. The second blocking member 28 is hollow inside, and multiple entrances 37 are opened at the upper end of the second blocking member 28. The entrances 37 are located between adjacent rollers 13, and the upper end of the second blocking member 28 is arranged in an arc shape; arc blocks 29 are hinged on both sides of the second blocking member 28, and the arc blocks 29 on both sides are mirror-distributed. The arc blocks 29 can block the air permeable grooves 24 at the upper side positions of the rollers 13, and a limiting rod 30 is passed through the arc block 29, and both ends of the limiting rod 30 pass through the channel 1.

[0051] The cold air is introduced into the roller 13 through the air duct 26, and the cold air in the roller 13 can be discharged into the channel 1 through the multiple air permeable grooves 24. Then, through the blocking effect of the arc blocks 29 and the second blocking member 28 on both sides, part of the cold air in the roller 13 can be discharged upward and partly discharged into the cavity between adjacent rollers 13. The cold air in the cavity between adjacent rollers 13 enters the middle roller 18 and is discharged through the air permeable grooves 24 above the middle roller 18. At the same time, the cold air in the cavity can also be discharged through the strip grooves 25 on the guide plate 22. Therefore, during the quick-freezing process, the bottom surface of the food is exposed to the cold air at the same time. Combined with the aforementioned top surface and side surface exposure, the temperature of the food can be quickly and evenly reduced, thereby achieving the quick-freezing effect more quickly.

[0052] Secondly, if the quick freezing process is uneven, large ice crystals may form, which will have a negative impact on the taste and texture of the food. The cold air acts evenly on all sides of the food, which helps to slow down the formation of ice crystals and thus maintain the quality of the food.

[0053] refer to Fig.11 and Fig.12 The guide plate 22 contacts the adjacent rollers 13 and the middle roller 18, and the rollers 13 and the middle roller 18 are in a rotating state and rotate counterclockwise. The guide plate 22 can scrape off the pollutants adhered to the surfaces of the rollers 13 and the middle roller 18, and the pollutants slide along the outer walls of the rollers 13 to the gaps between the rollers 13, and move toward the inlet 37 under their own weight, thereby collecting the pollutants inside the second blocking member 28, and then by taking out the limiting rods 30 on both sides and rotating the arc blocks 29 on both sides to separate the arc blocks 29 from the rollers 13, the second blocking member 28 can be taken out of the channel 1, and the garbage inside the second blocking member 28 can be cleaned.

[0054] Among them, a first scraper 31 is arranged inside the rotating roller 13, and a support rod 32 is fixedly connected to the first scraper 31. The support rod 32 passes through the rotating shaft on the rotating roller 13 and is fixedly connected to the channel 1. A second scraper 33 is arranged inside the middle roller 18, and a connecting rod 34 is fixedly connected to the channel 1. The connecting rod 34 passes through the rotating shaft on the middle roller 18 and is fixedly connected to multiple second scrapers 33.

[0055] During the cleaning process of the rotating roller 13 and the middle roller 18, a small amount of pollutants can fall into the rotating roller 13 and the middle roller 18 through the air-permeable groove 24, and the pollutants in the middle roller 18 can be discharged through the air-permeable groove 24 without being accumulated therein. After the second blocking member 28 is removed, the pollutants in the rotating roller 13 can be discharged through the air-permeable groove 24, and the pollutants will not be accumulated in the rotating roller 13. When the rotating roller 13 and the middle roller 18 are rotating, the first scraper 31 and the second scraper 33 can scrape the pollutants inside the rotating roller 13 and the middle roller 18 respectively to prevent the pollutants from adhering to the inner walls of the rotating roller 13 and the middle roller 18.

[0056] A storage tank 35 is placed in the channel 1, and the storage tank 35 is located at the lower end of one side of the arc block 29. Sealing curtains 36 are installed at both ends of the channel 1. A protective cover 39 is installed on the channel 1, and the first motor 16, the second motor 21, the first synchronous belt mechanism 14 and the second belt mechanism 19 are all located inside the protective cover 39. The protective cover 39 can protect the structure inside.

[0057] The multiple rotating rollers 13 can drive the food to move to one side in the channel 1. After being driven to the rollers 13 at the other end, the food can slide into the storage groove 35. The storage groove 35 can collect the food after quick freezing. The sealing curtains 36 on both sides can seal the two ends of the channel 1 to slow down the heat exchange rate between the inside of the channel 1 and the outside.

[0058] Overall working principle:

[0059] The refrigeration device 2 and the air pump 4 are working, and the air pump 4 guides the cold air into the pipe 6, and enters the air cavity 5 through the pipe 6, and then is discharged into the channel 1 through the multiple exhaust holes 10. The first motor 16 drives the driving wheel 17 to rotate, and the driving wheel 17 drives the driven wheel 15 to rotate, which can drive the rotating shaft of the roller 13 on one side to rotate. The roller 13 on one side rotates and is transmitted to the adjacent roller 13 through the first synchronous belt mechanism 14, which can drive multiple rollers 13 to rotate synchronously in the same direction, and the second motor 21 drives the second gear 38 to rotate, and the second gear 38 drives the first gear 20 to rotate. The first gear 20 and the rotating shaft of the middle roller 18 on one side rotate synchronously, and the middle roller 18 on one side drives the adjacent middle roller 18 to rotate through the second belt mechanism 19, so that multiple middle rollers 18 can be driven to rotate synchronously, and the middle roller 18 and the roller 13 have the same direction. The food is placed on the roller 13 on one side, and the multiple rotating rollers 13 and the middle roller 18 can drive the food to move smoothly to one side in the channel 1. The food is guided by multiple guide plates 22 to further improve the smoothness of the movement of the food in the channel 1.

[0060] Multiple exhaust holes 10 discharge cold air, which blows toward the upper side of the food. During the movement of the food, the food is continuously cooled by the cold air, thereby achieving quick freezing of the food. At the same time, the food can be continuously placed on the rotating roller 13 on one side to perform quick freezing of large quantities of food.

[0061] The cold air in the air cavity 5 can enter into the multiple extension tubes 9 and then be discharged from the exhaust holes 10 on the sides of the extension tubes 9, so that the cold air is blown to both sides of the food, thereby improving the freezing efficiency of the two sides of the food.

[0062] At the same time, the cold air is introduced into the roller 13 through the air guide 26, and the cold air in the roller 13 can be discharged into the channel 1 through the multiple air permeable grooves 24, and then through the blocking effect of the arc blocks 29 and the second blocking member 28 on both sides, the cold air in the roller 13 can be partially discharged upward and partially discharged into the cavity between adjacent rollers 13, and the cold air in the cavity between adjacent rollers 13 enters the middle roller 18 and is discharged through the air permeable groove 24 above the middle roller 18. At the same time, the cold air in the cavity can also be discharged through the strip groove 25 on the guide plate 22. Therefore, during the quick-freezing process, the bottom surface of the food is exposed to the cold air at the same time. Combined with the aforementioned top surface and side surface exposure, the temperature of the food can be quickly and evenly reduced, thereby achieving the quick-freezing effect more quickly.

[0063] When the food freezing work is suspended, the electromagnet 23 is energized so that the electromagnet 23 exerts a repulsive force on the sealing plug 7, so that the sealing plug 7 moves downward and blocks the connecting port between the pipeline 6 and the exhaust pipe of the air pump 4, thereby isolating the air cavity 5 from the outside world, avoiding heat exchange between the higher temperature air outside and the lower temperature air in the channel 1, and the channel 1 is in a heat-insulating state.

[0064] At the same time, the sealing plug 7, the connecting piece 11, the extension tube 9 and the guide plate 22 move synchronously, so that the guide plate 22 moves downward, the multiple springs 12 are compressed, and the bottom ends of the guide plate 22 contact the adjacent rollers 13 and the middle roller 18, and then drive the multiple rollers 13 and the middle roller 18 to rotate. There is an extrusion force between the guide plate 22 and the rollers 13 and the middle roller 18. The guide plate 22 can scrape off the pollutants adhering to the surface of the rollers 13 and the middle roller 18, and can clean the pollutants on the rollers 13 and the middle roller 18 in time to avoid the pollutants remaining for a long time and adhering to the roller surface more firmly. The cleaning method is convenient and the cleaning range covers the roller surface, and the cleaning effect is good. After the cleaning is completed, the electromagnet 23 is powered off, and the elastic force of the multiple springs 12 drives the sealing plug 7, the connecting piece 11, the extension tube 9 and the guide plate 22 to reset.
