Abstract
Description
Technical Field
[0001] This utility model relates to the field of canned food production technology, and in particular to a food can drying device. Background Technology
[0002] During the production process of canned food, after sterilization and cleaning, residual moisture often remains on the surface. Drying is necessary to ensure the product's appearance quality and shelf life. Traditional canning equipment typically uses a box-type drying structure, where a large number of cans are placed in a sealed box and dried using a hot air circulation system.
[0003] Existing drying devices typically suffer from the following technical drawbacks: 1. Hot air struggles to penetrate the gaps between cans, resulting in drying dead zones. Existing box-type drying devices usually arrange cans densely on trays or conveyor belts before sending them into the drying chamber for hot air drying. Due to the small gaps between cans, the hot air encounters significant resistance during flow, making it difficult to fully penetrate the internal areas of the can stack; 2. Traditional drying chambers are usually large in volume to accommodate batch production of cans, but the large internal space leads to uneven hot air distribution. After hot air enters from the air inlet, the airflow easily diffuses in all directions due to the open space inside the chamber. Utility Model Content

[0020] Example 1
[0021] like Figures 1-4 As shown in the figure, the food can drying device proposed in this embodiment includes a base plate 1, a turntable 2, a drying device, a pre-drying device, and multiple placement trays 11.
[0022] The chassis 1 is equipped with a mounting frame 5 and a bracket 4 at its upper and lower ends, respectively. It should be noted that a PLC controller is installed on the mounting frame 5. The turntable 2 is rotatably mounted on the chassis 1. Multiple limit holes 201 are opened along the annular array on the turntable 2. At least four limit holes 201 are provided. This arrangement ensures that the device has at least feeding, pre-drying, secondary drying and unloading stations. The various processes do not interfere with each other, which improves work efficiency. A servo motor 3 is installed on the chassis 1 to drive the rotation of the turntable 2.
[0023] The lower end of the placement tray 11 is provided with a limit frame 24, and multiple limit rings 22 are provided on the placement tray 11. Multiple through holes 111 are provided on the placement tray 11. In order to facilitate the staff to lift the placement tray 11, handles are installed at both ends of the placement tray 11.
[0024] The drying device includes a mounting plate 6, an electric push rod 10, and multiple drying components. The mounting plate 6 is located above the turntable 2 and has a top cover 14. The electric push rod 10 is mounted on the mounting frame 5 and its output shaft is connected to the top cover 14. When the placement tray 11 moves to the position directly below the mounting plate 6, multiple drying components are set up one-to-one with multiple limiting rings 22. The drying components include an outer cover 7, a second nozzle 16, and a second nozzle connecting pipe 18. The outer cover 7 is located below the mounting plate 6, and the third nozzle 17 is located at the top of the inner wall of the outer cover 7. The second nozzle 16 has a ring structure and is located inside the outer cover 7. An elastic component is connected between the second nozzle 16 and the outer cover 7. The elastic component includes a guide rod 20, a spring 21, and a limiting block. The guide rod 20 moves through the mounting plate 6 and the upper end of the outer cover 7. The two ends of the guide rod 20 are connected to the second nozzle 16 and the limiting block, respectively. The spring 21 is sleeved on the guide rod 20.
[0025] The mounting frame 5 is equipped with a heating device for supplying hot air to multiple second nozzles 16 and multiple third nozzles 17. The heating device includes a heating box 8 and a fan 9. Both the heating box 8 and the fan 9 are mounted on the mounting frame 5. An electric heater is installed inside the heating box 8. A pipe is connected between the output end of the fan 9 and the inner cavity of the heating box 8. The other end of the heating box 8 is connected to a first high-temperature resistant hose. The other end of the first high-temperature resistant hose is connected to a distributor. The distributor is installed inside the top cover 14. The second nozzles 16 and the third nozzles 17 are respectively connected to a second nozzle connecting pipe 18 and a third nozzle connecting pipe 19. Both the second nozzle connecting pipe 18 and the third nozzle connecting pipe 19 movably pass through the mounting plate 6. The input ends of the second nozzle connecting pipe 18 and the third nozzle connecting pipe 19 are connected to multiple output ends of the distributor via second high-temperature resistant hoses.
[0026] The pre-drying device includes a connecting pipe 12 and multiple first nozzles 15. The input end of the connecting pipe 12 passes through the chassis 1 and is flush with the upper end of the chassis 1. The input end of the connecting pipe 12 is located directly below the mounting plate 6. Multiple first nozzles 15 are arranged side by side above the turntable 2. The input ends of multiple first nozzles 15 are all connected to the output end of the connecting pipe 12. It should be noted that there are three first nozzles 15. The output end of the connecting pipe 12 is connected to a four-way connector, and the three first nozzles 15 are connected to the three output ends of the four-way connector through branch pipes 13.
[0027] In this embodiment, the worker places multiple cans to be dried on the placement tray 11, so that the bottom of the multiple cans is placed inside the multiple limiting rings 22 respectively, which is used to limit the cans. Then, the placement tray 11 is placed above the limiting hole 201 of the corresponding side feeding area, so that the limiting frame 24 is placed inside the limiting hole 201, which is used to limit the horizontal movement of the placement tray 11.
[0028] The servo motor 3 drives the turntable 2 to rotate intermittently. The single rotation angle of the turntable 2 is 360 / N, where N is the number of limiting holes 201. When the placement tray 11 rotates to the position directly below the mounting plate 6, the turntable 2 stops rotating. Then, the electric push rod 10 drives the mounting plate 6 to move downwards, and the outer cover 7 gradually moves downwards until it contacts the upper surface of the placement tray 11. At this time, multiple cans are located inside multiple outer covers 7. The outer covers 7 prevent hot air from escaping quickly and improve the utilization efficiency of hot air. Meanwhile, a heating device delivers hot air to multiple second nozzles 16 and third nozzles 17. The hot air ejected from the third nozzle 17 blows towards the top of the can, while the hot air ejected from the second nozzles 16 blows towards the periphery of the can. As the mounting plate 6 continues to move downward, the outer cover 7 is limited by the placement plate 11 and cannot continue to move downward. At this time, the spring 21 is compressed, and the second nozzle 16 moves downward relative to the outer cover 7, thereby increasing the range of movement of the outer cover 7 and allowing the surface water stains of the can to be fully dried.
[0029] During the drying process, the hot air discharged through the through hole 111 enters the limiting hole 201 at the bottom and finally flows through the connecting pipe 12 to multiple branch pipes 13. The multiple branch pipes 13 are set up as the next station of the material discharge area, thereby enabling the pre-drying of multiple cans, reducing the time of secondary drying, and effectively improving energy utilization efficiency.
[0030] After the drying process is completed, drive the mounting plate 6 to move upward and reset, then drive the turntable 2 to rotate to the next station. At this time, the operator can remove the dried canned goods together with the placement tray 11.
[0031] Example 2
[0032] like Figure 4 As shown, the food can drying device proposed in this embodiment has multiple notches 221 on the limiting ring 22 compared to the first embodiment. A wire mesh frame 23 is provided on the inner side of the limiting ring 22, and there is a gap between the wire mesh frame 23 and the placement tray 11. With the above structure, the hot air inside the outer cover 7 can be blown to the bottom of the can through the notches 221 and the gap below the wire mesh frame 23, so as to reduce the drying dead corners and allow the surface of the can to be fully dried.
[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
