[0039] The following will be combined with the accompanying drawings in 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.

[0040] For examples, see Figure 1 , Figure 2 and Figure 3 As shown, the purpose of this embodiment is to provide a cooked grain cooling device for liquor production, including a device body 1, the device body 1 includes a cooling box 11, the interior of the cooling box 11 forms a cooling chamber 10, one side of the cooling box 11 is connected to a feed pipe 12, the interior of the feed pipe 12 is connected to the cooling chamber 10, a discharge port 13 is provided on the side of the cooling chamber 10 away from the feed pipe 12, a discharge guide plate 14 is provided at the lower end of the opening of the discharge port 13, and the upper end of the inner cavity of the cooling chamber 10 is covered by a combination of multiple leaf plates 15;

[0041] A cooling assembly 2 is provided inside the cooling chamber 10, and the cooling assembly 2 includes a turning-over mechanism 21 and a driving mechanism 22. The driving mechanism 22 is located on the outer wall of the cooling box 11, and the turning-over mechanism 21 is used to place and cool cooked grains. The turning-over mechanism 21 is connected to the driving mechanism 22. When the driving mechanism 22 drives the turning-over mechanism 21 to rotate, the cooked grains can be turned over to prevent sticking. At the same time, the rotation of the turning-over mechanism 21 is also used to drive the cooked grains to be transported.

[0042] When cooling the cooked grain, it is necessary to place the cooked grain on the surface of the turning-over mechanism 21 in the cooling chamber 10. The specific structure of the turning-over mechanism 21 is disclosed below. The turning-over mechanism 21 includes a placing cover 213. The left and right ends of the placing cover 213 are fixedly connected to the inner wall of the cooling chamber 10. The left and right widths of the placing cover 213 are greater than the width of the cooling chamber 10. The placing cover 213 divides the cooling chamber 10 into a turning-over chamber 101 and a driving chamber 102. A plurality of turning wheel groups 211 are arranged inside the driving chamber 102. Bottom air cooling groups 212 are arranged inside the plurality of turning wheel groups 211. A top air cooling component 214 is installed on the top of the cooling box 11.

[0043] See also Figure 2 As shown, the left and right sides of the placement cover 213 are fixedly connected to the cooling chamber 10, one side is close to the feed pipe 12, and the other side is close to the discharge port 13, and the size of the placement cover 213 is wider than the internal size of the cooling chamber 10, so that the placement cover 213 can be set on the surface of multiple wheel groups 211, such as Figure 3 As shown, the installation height of the placement cover 213 is lower than the opening position of the feed pipe 12 , so that when the cooked grain enters the cooling chamber 10 from the feed pipe 12 , it can directly fall onto the surface of the placement cover 213 .

[0044] Next, the specific structure of the wheel assembly 211 is disclosed. The wheel assembly 211 includes a wheel body 31 rotatably mounted inside the driving cavity 102 . The wheel body 31 is used to support the placement cover 213 . A guide bar plate 32 is fixedly mounted on the surface of the wheel body 31 .

[0045] The specific structure of the bottom air cooling group 212 is disclosed below. The bottom air cooling group 212 includes a middle cavity 41 opened inside the flap body 31. The inner wall of the middle cavity 41 is provided with a plurality of flow holes 42. A middle axis 45 is movably provided inside the middle cavity 41. A plurality of wind wheel fans 43 are installed on the surface of the middle axis 45. One end of the middle axis 45 extends out of the surface of the flap body 31. A connecting pipe 44 is fixedly connected to the outer wall of one side of the flap body 31. The connecting pipe 44 is sleeved on the surface of the middle axis 45.

[0046] The driving mechanism 22 includes a cover shell 224, which is fixedly connected to the outer wall of the cooling box 11. A plurality of double gears 221 are arranged inside the cover shell 224. A plurality of inner holes are opened at one end of the cooling box 11 close to the cover shell 224. The connecting pipe 44 and the central axis 45 are both located inside the inner holes. The end of the connecting pipe 44 away from the tipping wheel body 31 is fixedly connected to the outer gear of the double gear 221, and the end of the central axis 45 away from the tipping wheel body 31 is fixedly connected to the inner gear of the double gear 221.

[0047] The multiple double gears 221 are all meshed and connected with the connecting chain 225 , wherein the rotating shaft of one of the double gears 221 is fixedly connected to one of the output shafts of the right angle gear box 223 , and the other output shaft of the right angle gear box 223 is fixedly connected to the output shaft of the driving motor 222 .

[0048] The placement cover 213 is made of breathable material.

[0049] After being steamed, the cooked grain enters the cooling chamber 10 through the feed pipe 12. Initially, the cooked grain is accumulated on the surface of one end of the placement cover 213 close to the feed pipe 12. Then, the drive motor 222 is started, and the cooling chamber 10 is cooled. Figure 2 , Figure 6 and Figure 7 As shown, after the driving motor 222 is started, it will drive one of the double gears 221 to rotate. Since the multiple double gears 221 are meshed with each other through the connecting chain 225, when one of the double gears 221 rotates, the other double gears 221 will also operate at the same speed and in the same direction. Figure 8 and Fig.10 As shown, the surface of each double gear 221 is connected to a wheel body 31 through a connecting pipe 44, so that when the double gear 221 rotates, the wheel body 31 will also rotate synchronously. During the rotation of the wheel body 31, the guide bar plate 32 connected to its surface will scrape the placement cover 213, so that the cooked grains accumulated on one side of the feed pipe 12 can be turned over and transported toward the end close to the discharge port 13. During this turning and transporting process, the cooling position of the cooked grains is constantly changed, thereby reducing the situation where the cooked grains stick to each other. In addition, combined with Figure 5 As shown, the plurality of wheel bodies 31 rotate clockwise to continuously push the cooked grains toward the discharge port 13. Thus, the cooked grains can be collected in time after being cooled to a certain degree, thereby effectively reducing the overcooling of the cooked grains and ensuring product quality.

[0050] Combination Figure 6 and Figure 8As shown, the inner gear of the double gear 221 is fixedly connected to the middle shaft 45. When the double gear 221 rotates, the middle shaft 45 will rotate synchronously in the middle cavity 41 opened in the middle of the flap body 31. The rotation of the middle shaft 45 can drive the multiple wind wheel fans 43 fixed on its surface to rotate together. The wind flow formed by the rotation of the multiple wind wheel fans 43 will be blown out from the multiple flow holes 42 opened on the surface of the flap body 31. The blown air enters the driving cavity 102, causing the overall temperature of the driving cavity 102 to drop.

[0051] Since the driving chamber 102 and the cover shell 224 are interconnected, the lowered temperature in the driving chamber 102 can be diffused into the cover shell 224, thereby cooling the cover shell 224. In this way, the adverse effect of the heat generated by the double gears 221 and the connecting chain 225 during the rotation on the cooked grain cooling effect can be reduced, thereby ensuring the smooth progress of the cooked grain cooling process.

[0052] The above-mentioned placement cover 213 is preferably made of food-grade nylon mesh. Food-grade nylon mesh is a mesh material woven from nylon fibers. Nylon fibers have good softness. After being woven into a mesh, it is light and soft. The mesh structure reduces the possibility of cooked grains and materials coming into contact with a large area and sticking together. At the same time, the nylon mesh has good air permeability.

[0053] like Figure 1 As shown, a top air cooling component 214 is installed on the top of the cooling box 11, and the top air cooling component 214 includes a support plate, and two cooling fans are installed inside the support plate. The two cooling fans are driven by a motor. When the two cooling fans rotate, the wind force generated by the rotation of the two cooling fans can pass through the gap between the leaf plates 15 and enter the interior of the cooling chamber 10, thereby achieving the effect of auxiliary cooling of the turning cold chamber 101.

[0054] See also Figure 3 As shown, by means of the top air cooling component 214 and the placement cover 213 made of breathable material, the two cooperate with each other to achieve two-way air cooling of the cooked grain. Specifically, the top air cooling component 214 blows out cold air, and the cold air enters the cooling chamber 101 to cool the cooling chamber 101, while the breathable material of the placement cover 213 allows the air in the driving chamber 102 to enter and contact the cooked grain. On the other hand, the heat dissipated by the cooked grain can also be dissipated outward through the breathable material, which is equivalent to constructing a cooling path from the bottom. The synergistic effect of the upper and lower parts greatly improves the cooling efficiency of the cooked grain.

[0055] It should be noted that the overall length of the equipment body 1 and the number of the wheel bodies 31 are not fixed, but need to be determined based on the results of the cooling test of the cooked grain. Through the cooling test, the cooling time of the cooked grain in the cooling chamber 10 can be accurately controlled to ensure that the cooked grain is in a suitable temperature range when it arrives at the discharge port 13. The length shown in the figure is for reference only.

[0056] In order to allow the cooled cooked grain to be discharged more smoothly and reduce the situation where the discharge port 13 is blocked by accumulation, the end of the placement cover 213 close to the discharge port 13 is in an inclined state.

[0057] The improvements are: See Figure 4 As shown, one end of the placement cover 213 close to the discharge port 13 is designed to be in an inclined state. With the natural traction of gravity, the cooked grains will smoothly flow along the inclined surface toward the discharge port 13, achieving rapid discharge and ensuring the smoothness of the entire cooked grain cooling and discharge process.

[0058] In order to further enhance the air cooling effect at the bottom of the cooked grain, the inner walls of the plurality of flow holes 42 are all outwardly expanded structures to expand the blowing area of ​​the air cooling.

[0059] The improvement lies in: combining Fig. 9 It can be seen that the inner walls of the multiple circulation holes 42 are designed as an outward expansion structure, so that when the cold air flows through the circulation holes 42, the blowing path is widened, and can act on the cooked grain over a large area, effectively expanding the blowing area of ​​the air cooling, and ultimately achieving an increase in the air cooling area and improving the cooling effect.

[0060] During the turning and conveying of cooked grains, the turning wheel body 31 drives the guide strips 32 to continuously scrape the placement cover 213. The placement cover 213 is made of a breathable material and is relatively thin. The guide strips 32 can easily scratch the surface of the cooked grains when scraping frequently, which can easily damage the internal structure of the cooked grains and cause the loss of nutrients. Therefore, the ends of the multiple guide strips 32 away from the turning wheel body 31 are fixedly connected with side strips 5, and the surfaces of the multiple side strips 5 are all smooth structures.

[0061] The improvements are: See Figure 5 Combined with Figure 8 As shown, a plurality of guide plates 32 are fixedly connected to one end away from the turning wheel body 31 with a side strip 5, and the surface of the side strip 5 is a smooth structure. When the guide plates 32 push the cooked grains to move, the smooth side strips 5 can reduce the hard friction with the cooked grains to a certain extent, thereby reducing the scraping damage to the cooked grains.

[0062] In summary, the working principle of this scheme is as follows: after being steamed, the cooked grain enters the cooling chamber 10 through the feed pipe 12. Initially, the cooked grain will accumulate on the surface of one end of the placement cover 213 close to the feed pipe 12. Then, the driving motor 222 is started to drive one of the double gears 221 to rotate. Since the multiple double gears 221 are meshed with each other through the connecting chain 225, when one of the double gears 221 rotates, the other double gears 221 will also operate at the same speed and in the same direction. The surface of each double gear 221 is connected to a wheel body 31 through a connecting pipe 44, which makes the double gear 221 When rotating, the wheel body 31 will also rotate synchronously. During the rotation of the wheel body 31, the guide bar plate 32 connected to its surface will scrape the placement cover 213, so that the cooked grains accumulated on one side of the feeding pipe 12 can be turned over and transported toward the end close to the discharge port 13. During this turning and transporting process, the cooling position of the cooked grains is constantly changed, thereby reducing the situation where the cooked grains stick to each other. The multiple wheel bodies 31 all rotate clockwise and continuously push the cooked grains toward the discharge port 13. In this way, the cooked grains can be collected in time after being cooled to a certain degree, effectively reducing the situation where the cooked grains are overcooled and ensuring the product quality.

[0063] The inner gear of the double gear 221 is fixedly connected to the central shaft 45. When the double gear 221 rotates, the central shaft 45 will rotate synchronously in the central cavity 41 opened in the middle of the flap body 31. The rotation of the central shaft 45 can drive the multiple wind wheel fans 43 fixed on its surface to rotate together. The wind flow formed by the rotation of the multiple wind wheel fans 43 will be blown out from the multiple flow holes 42 opened on the surface of the flap body 31. The blown air enters the driving cavity 102, causing the overall temperature of the driving cavity 102 to drop.

[0064] The top wind cooling component 214 blows out cold air, which enters the cooling chamber 101 to cool the cooling chamber 101. The breathable material of the placement cover 213 allows the air in the driving chamber 102 to enter and contact the cooked grains. On the other hand, the heat emitted by the cooked grains can also be dissipated outwards through the breathable material, which is equivalent to constructing a cooling path from the bottom. The synergistic effect of the upper and lower parts improves the cooling effect of the cooked grains.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
