Description

Technical Field

[0001] The invention relates to the technical field of air-drying air-dried chicken, in particular to a fermentation-controlled circulating air-drying system for air-dried chicken. Background Art

[0002] Air-dried chicken is a traditional delicacy. This kind of chicken is easy to preserve and fresh, mellow, tender, suitable for all ages, and deeply loved by local people. There are many ways to make air-dried chicken, including pickling, braising, air-drying and smoking, and it can be cooked in a variety of ways such as steaming or frying, among which a special air-drying technology is involved.

[0003] For example, a Chinese patent with publication number CN116897987A discloses a closed-loop green preparation device and process for air-dried chicken, including an air-drying box, a fan, a filtering device and a supporting mechanism. When in use, the filtering device removes the odor generated by the air-dried chicken during the drying process, and the supporting device opens the air-dried chicken from the inside so that the inside of the air-dried chicken is in direct contact with the air, thereby increasing the contact area between the air-dried chicken and the circulating airflow and improving the drying efficiency of the air-dried chicken.

[0004] However, the above-mentioned air-dried chicken closed-loop green preparation device still has some shortcomings in actual use:

[0005] 1. Firstly, the above-mentioned prior art only uses a supporting device to open the air-dried chicken from the inside so that the inside of the air-dried chicken can be in contact with the air, thereby improving the air-drying efficiency inside the air-dried chicken. However, the air flow rate inside the air-dried chicken is still much lower than the air flow rate outside the air-dried chicken, resulting in uneven air-drying, which will eventually make the taste and flavor inside and outside of the air-dried chicken inconsistent, affecting the product quality.

[0006] 2. Secondly, the above-mentioned prior art only uses a supporting device to open the air-dried chicken from the inside to increase the contact area between the air-dried chicken and the circulating airflow. However, the air flow rate is not enhanced, the air-drying time is not greatly improved, and the air-drying efficiency is still very low.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing air-drying technology for air-dried chicken. Summary of the invention

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-Figure 8While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0036] The embodiment of the present application discloses a fermentation-controlled circulating air-drying system for air-dried chicken, which explains that the fermentation-controlled circulating air-drying system for air-dried chicken is mainly used in the air-drying process of air-dried chicken, and can avoid the problem of uneven air-drying of the air-dried chicken in terms of technical effect, thereby ensuring the consistency of the taste and flavor of the air-dried chicken and improving the quality of the air-dried chicken; further, the present invention can greatly increase the air flow rate around the air-dried chicken, thereby improving the air-drying efficiency, shortening the drying time of the air-dried chicken, and thus saving time cost.

[0037] Embodiment 1:

[0038] Reference Figure 1 and Figure 2 As shown, a fermentation-controlled circulating air-drying system for air-dried chicken comprises a closed box 1, a bracket 2 and an air-drying mechanism 3. The closed box 1 is arranged on the ground to provide a closed sterile environment. A plurality of brackets 2 distributed in a matrix are arranged in the closed box 1. The bracket 2 serves as a carrier to carry the air-drying mechanism 3. The air-drying mechanism 3 is arranged on the top of the bracket 2. The air-drying mechanism 3 has the functions of hanging the air-dried chicken, driving the air-dried chicken to rotate and accelerating the air flow rate.

[0039] The air-drying mechanism 3 includes a connecting shaft 30, a load-bearing plate 31, a rotating fan blade 32, a load-bearing ring 33, a load-bearing frame 34 and a semicircular hook 35. A plurality of connecting shafts 30 equidistantly distributed along the length direction of the bracket 2 are passed through the top of the bracket 2. The connecting shaft 30 is installed on the top of the bracket 2 through a bearing, and can rotate around an axial direction, and the axial direction is perpendicular to the top of the bracket 2. The horizontally placed load-bearing plate 31 is arranged at one end of the connecting shaft 30 away from the top of the bracket 2, and the load-bearing plate 31 is used to bear the load-bearing ring 33. The rotating fan blade 32 is horizontally arranged on the connecting shaft 30, and the center of the rotating fan blade 32 is located at the connecting shaft 30. On the axis line of the connecting shaft 30, the rotating fan blades 32 are located between the load-bearing plate 31 and the top of the bracket 2. The rotating fan blades 32 are used to provide an airflow from top to bottom to accelerate the air flow rate around the air-dried chicken. The load-bearing ring 33 is horizontally sleeved on the connecting shaft 30 and is located between the rotating fan blades 32 and the load-bearing plate 31. A number of load-bearing frames 34 distributed in a ring shape are arranged on the outer ring surface of the load-bearing ring 33. The load-bearing frame 34 is used to carry the semicircular hooks 35 and the air-dried chicken, and has strong rigidity. A number of semicircular hooks 35 are evenly spaced on the load-bearing frame 34, and the semicircular hooks 35 are used to hang the air-dried chicken.

[0040] First, the air-dried chicken is hung on the semicircular hook 35. The hung air-dried chicken should avoid mutual interference, and there should be enough space between the air-dried chickens to facilitate air flow, so as to prevent the air circulation from being affected by hanging the air-dried chickens too densely, resulting in a reduction in air flow rate and affecting the air-drying efficiency.

[0041] Reference Figure 3 As shown, the bracket 2 is also provided with a DC motor 20 for providing the power required for the connection shaft 30 to rotate. The DC motor 20 is arranged at the top of the bracket 2, and its output end passes through the top of the bracket 2 and is coaxially connected to a connection shaft 30 on the corresponding bracket 2. The DC motor 20 is used to provide power to drive the connection shaft 30 to rotate.

[0042] It should be noted that the DC motor 20 is an existing known structure and is an electric motor that converts electrical energy into mechanical energy. It has the advantages of high efficiency, energy saving, environmental protection, and easy maintenance, and is widely used in industrial production, transportation, medical equipment and other fields.

[0043] During the specific implementation process, when all the air-dried chickens are hung, the DC motor 20 is started, and the output shaft of the DC motor 20 rotates at a high speed, thereby driving the connecting shaft 30 to rotate synchronously, and finally the connecting shaft 30 drives the bearing plate 31 to rotate synchronously.

[0044] Replay Figure 3 A transmission gear 300 is also provided on the connecting shaft 30, and its rotation center is located on the axis of the connecting shaft 30. The transmission gear 300 and the connecting shaft 30 remain stationary or rotate synchronously, and a transmission belt 301 is meshed with the transmission gear 300.

[0045] In the specific implementation process, when the connecting shaft 30 rotates, it drives the transmission gear 300 to rotate synchronously, and the transmission gear 300 drives the transmission belt 301 to rotate, so that the remaining transmission gears 300 engaged on the transmission belt 301 start to rotate, and finally these transmission gears 300 drive the corresponding connecting shaft 30 to rotate.

[0046] It should be noted that only one connecting shaft 30 on a bracket 2 is installed with a DC motor 20, and the other connecting shafts 30 are driven by the transmission belt 301 to keep synchronous rotation, and the structures of the connecting shafts 30 except the DC motor 20 are the same.

[0047] Reference Figure 5 As shown, two semicircular lower friction plates 310 are also provided on the load-bearing plate 31, and the two lower friction plates 310 are connected by bolts and nuts to form a complete circular ring. The two lower friction plates 310 are sleeved on the connecting shaft 30 and are located at the top of the load-bearing plate 31; two semicircular upper friction plates 330 are also provided on the load-bearing circular ring 33, and the two upper friction plates 330 are connected by bolts and nuts to form a complete circular ring. The two semicircular upper friction plates 330 are sleeved on the connecting shaft 30 and are located at the bottom of the load-bearing circular ring 33.

[0048] Replay Figure 5In order to allow the lower friction plate 310 to be installed on the load-bearing plate 31 and the upper friction plate 330 to be installed on the load-bearing ring 33, positioning columns 3100 are also provided on the upper friction plate 330 and the lower friction plate 310. The positioning columns 3100 are arranged on the arc surfaces of the upper friction plate 330 and the lower friction plate 310, and positioning grooves 3101 for the positioning columns 3100 to be engaged are opened on the load-bearing plate 31 and the load-bearing ring 33.

[0049] It should be noted that this structure has the function of facilitating installation and disassembly. When installation is required, the positioning columns 3100 of the two upper friction disks 330 are clamped with the positioning grooves 3101 of the load-bearing ring 33, and the upper friction disks 330 are fitted with the bottom of the load-bearing ring 33, and tightened with bolts and nuts; similarly, the positioning columns 3100 of the two lower friction disks 310 are clamped with the positioning grooves 3101 of the load-bearing disk 31, and the lower friction disk 310 is fitted with the top of the load-bearing disk 31, and the installation can be completed by tightening the bolts and nuts; when disassembly is required, just loosen the bolts and nuts, pull out the upper friction disk 330 and the lower friction disk 310 horizontally, and the disassembly can be completed.

[0050] Secondly, under the clamping action of the positioning column 3100 and the positioning groove 3101, the upper friction plate 330 and the load-bearing ring 33 keep rotating synchronously, and the lower friction plate 310 and the load-bearing plate 31 keep rotating synchronously.

[0051] Finally, the contact surface between the upper friction disc 330 and the lower friction disc 310 is designed to be a rough surface, and friction is generated when the two rotate. In the initial state, when the load-bearing disc 31 rotates at a high speed, under the clamping action of the positioning column 3100 and the positioning groove 3101, it drives the lower friction disc 310 to rotate synchronously at a high speed. Then, under the friction force of the lower friction disc 310, the upper friction disc 330 begins to rotate accordingly, and then the upper friction disc 330 drives the load-bearing ring 33 to rotate synchronously, and the load-bearing ring 33 drives the load-bearing frame 34 to rotate synchronously, and finally the load-bearing frame 34 drives the semicircular hook 35 to rotate synchronously.

[0052] During the specific implementation process, when the load-bearing plate 31 rotates rapidly, it drives the lower friction plate 310 to rotate synchronously. Under the action of the friction force between the upper friction plate 330 and the lower friction plate 310, the upper friction plate 330 starts to rotate in the same direction but at different speeds. Then the upper friction plate 330 drives the load-bearing ring 33 to rotate synchronously, and then the load-bearing frame 34 installed on the load-bearing ring 33 rotates synchronously. Finally, the semicircular hook 35 installed on the load-bearing frame 34 keeps rotating synchronously, so the air-dried chicken hung on the semicircular hook 35 rotates synchronously therewith.

[0053] Reference Figure 4As shown, the speed control unit 4 for adjusting the rotation speed of the air-dried chicken in the present invention comprises a pressure ring 40, a square column 41 and a hydraulic cylinder 42. The pressure ring 40 is sleeved on the connecting shaft 30 and is located on the top of the load-bearing ring 33 to provide a vertical downward pressure. A plurality of square columns 41 distributed along the length direction of the bracket 2 are arranged on the outer ring surface of the pressure ring 40 and are integrally connected with the pressure ring 40. Two symmetrically distributed hydraulic cylinders 42 are arranged on the bracket 2, and their output ends abut against the top of the square column 41. When the output ends thereof move downward, the output ends of the hydraulic cylinders 42 directly abut against the square column 41 and cannot move. Therefore, when the output ends of the hydraulic cylinders 42 have a tendency to move downward, it will be converted into a downward thrust and provided on the square column 41 and the pressure ring 40.

[0054] It should be noted that when it is necessary to adjust the rotation speed of the semicircular hook 35, it is only necessary to adjust the downward thrust of the output end of the hydraulic cylinder 42. When the thrust of the output end of the hydraulic cylinder 42 increases, the thrust acting on the square column 41 and the pressure ring 40 increases, and then the thrust of the pressure ring 40 acting on the load-bearing ring 33 increases. Because the pressure increases, the friction force will become larger, so the friction force between the pressure ring 40 and the load-bearing ring 33 increases, and the kinetic energy of the load-bearing ring 33 is consumed during rotation through the friction force, thereby achieving the effect of reducing the rotation speed of the load-bearing ring 33; on the contrary, when the thrust of the output end of the hydraulic cylinder 42 decreases, the rotation speed of the load-bearing ring 33 will increase.

[0055] During the specific implementation process, when the semicircular hook 35 rotates, it drives the air-dried chicken to rotate. When the air-dried chicken rotates too fast, it will cause the equipment to be unstable and easily cause damage to the equipment. At the same time, there is a risk of the air-dried chicken being thrown out; when the air-dried chicken rotates too slowly, the air flow slows down, and there is a difference in wind speed inside and outside the air-dried chicken, resulting in uneven drying.

[0056] Therefore, when it is necessary to adjust the speed of the air-dried chicken, the thrust at the output end of the hydraulic cylinder 42 is increased, and the speed of the air-dried chicken is reduced; the thrust at the output end of the hydraulic cylinder 42 is reduced, and the speed of the air-dried chicken is increased.

[0057] Reference Figure 6 As shown, due to the long-term friction between the upper friction plate 330 and the lower friction plate 310, debris is generated. Therefore, an upper protective cover 340 and a lower protective cover 341 are also provided on the load-bearing frame 34. The upper protective cover 340 and the lower protective cover 341 are sleeved on the load-bearing frame 34. The upper protective cover 340 and the lower protective cover 341 are connected by bolts and nuts, and the upper protective cover 340 and the lower protective cover 341 form a cylindrical shell sleeved on the load-bearing frame 34, which is wrapped with a load-bearing ring 33, a load-bearing plate 31, an upper friction plate 330 and a lower friction plate 310 to prevent the generated debris from falling onto the air-dried chicken, thereby preventing the debris from affecting the appearance and taste of the air-dried chicken.

[0058] Reference Figure 7 As shown, the sliding assembly 5 for moving the bracket 2 in the present invention includes a mushroom-shaped disc 50, an annular pulley 51, a connecting block 52 and a circular pulley 53. A plurality of mushroom-shaped discs 50 distributed in a rectangular shape are arranged at the bottom of the bracket 2, and the tail of the mushroom-shaped disc 50 touches the bottom of the bracket 2. The annular pulley 51 is sleeved on the mushroom-shaped disc 50 and is located between the mushroom-shaped disc 50 and the bracket 2. The symmetrically distributed connecting blocks 52 are arranged on the outer ring surface of the annular pulley 51. The circular pulley 53 is arranged on the connecting block 52 through a bearing and is located between the two connecting blocks 52.

[0059] It should be noted that the annular pulley 51 is used for 360° rotation in the horizontal direction, and the circular pulley 53 is used for 360° rotation in the vertical direction. The combination of the two enables the sliding assembly 5 to rotate without dead angles, thereby enabling the bracket 2 to move freely in the closed box 1.

[0060] Embodiment 2:

[0061] Replay Figure 1 On the basis of the first embodiment, in order to make the air in the closed box 1 flow faster, specifically, a row of circulation fans 6 are also provided in the closed box 1, and the circulation fans 6 include an outlet fan and an inlet fan, and the outlet fan and the inlet fan are both provided in the closed box 1.

[0062] It should be noted that the circulating fan 6 is an existing known structure, which consists of a fan body, a motor, a variable frequency speed regulation system, an inlet electric baffle and a detection system. It meets the needs of different application scenarios by delivering gas with a specific temperature and specific humidity to the outside.

[0063] Reference Figure 8 As shown, in order to extend the service life of the circulation fan, a number of limit blocks 60 are arranged at equal intervals on the outer wall of the circulation fan 6, and the air outlet and air inlet of the circulation fan 6 are both provided with a protective cover 61 for filtering the circulating air in the closed box 1. The protective cover 61 also has a limit groove 62 for rotatably installing the protective cover 61 and the limit block 60.

[0064] This structure has the function of convenient disassembly and installation. When installing the protective cover 61, it is only necessary to align the entrance of the limit groove 62 of the protective cover 61 with the limit block 60, and then move the protective cover 61 according to the path of the limit groove 62. Under the action of gravity, the limit block 60 abuts against the terminal end of the limit groove 62, so that the protective cover 61 is installed on the circulating fan 6; similarly, when uninstalling the protective cover 61, the limit block 60 is moved to the entrance of the limit groove 62 of the protective cover 61 according to the path of the limit groove 62.

[0065] During the specific implementation process, after the air-dried chicken is hung, the circulating fan 6 is started to blow out gas with a specific temperature and specific humidity. The gas outlet continuously outputs gas, and the gas inlet continuously inhales gas, so that the gas in the closed box 1 circulates.

[0066] Driven by the DC motor 20, the air-dried chicken keeps rotating, so that the surrounding air is blown toward the air-dried chicken evenly. At the same time, the rotating fan blades 32 on the connecting shaft 30 rotate rapidly under the drive of the DC motor 20, providing air blowing from top to bottom to the air-dried chicken, accelerating the flow of air around the air-dried chicken, and making the flow direction of air around the air-dried chicken more varied, so that the taste and flavor of the air-dried chicken are more balanced after drying.

[0067] During operation: First, the air-dried chickens are hung on the semicircular hooks 35. The hung air-dried chickens should not interfere with each other, and there should be enough space between the air-dried chickens.

[0068] Step 2: When all the air-dried chickens are hung, start the DC motor 20, and the output shaft of the DC motor 20 rotates at a high speed, thereby driving the connecting shaft 30 to rotate synchronously, and finally the connecting shaft 30 drives the load-bearing plate 31 to rotate synchronously. At the same time, the connecting shaft 30 drives the transmission gear 300 to rotate synchronously, and the transmission gear 300 drives the transmission belt 301 to rotate, so that the remaining transmission gears 300 engaged on the transmission belt 301 start to rotate, and finally these transmission gears 300 drive the corresponding connecting shafts 30 to rotate.

[0069] Step 3: When the load-bearing plate 31 rotates rapidly, it drives the lower friction plate 310 to rotate synchronously. Under the action of the friction force between the upper friction plate 330 and the lower friction plate 310, the upper friction plate 330 starts to rotate in the same direction but at different speeds. Then the upper friction plate 330 drives the load-bearing ring 33 to rotate synchronously, and then the load-bearing frame 34 installed on the load-bearing ring 33 rotates synchronously. Finally, the semicircular hook 35 installed on the load-bearing frame 34 keeps rotating synchronously, so the air-dried chicken hanging on the semicircular hook 35 rotates synchronously.

[0070] Step 4: When it is necessary to adjust the speed of the air-dried chicken, increase the thrust at the output end of the hydraulic cylinder 42 to reduce the speed of the air-dried chicken; reduce the thrust at the output end of the hydraulic cylinder 42 to increase the speed of the air-dried chicken.

[0071] Step 5: Start the circulating fan 6 to blow out gas with a specific temperature and a specific humidity. The gas outlet continuously outputs gas, and the gas inlet continuously inhales gas, so that the gas in the closed box 1 circulates; driven by the DC motor 20, the air-dried chicken keeps rotating, so that the surrounding gas is evenly blown to the air-dried chicken. At the same time, the rotating fan blades 32 on the connecting shaft 30 are driven by the DC motor 20 to rotate rapidly, providing gas blowing from top to bottom to the air-dried chicken, accelerating the flow of air around the air-dried chicken, and making the gas flow direction around the air-dried chicken more varied, so that the taste and flavor of the air-dried chicken are more balanced after air drying.

[0072] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
