Description

Technical Field

[0001] This utility model relates to the field of pastry production technology, specifically a rotary oven for pastry baking. Background Technology

[0002] In the pastry baking industry, the performance of baking equipment directly affects the quality of pastries. Rotary ovens, in particular, are widely used in the large-scale production of various pastries because they can heat pastries more evenly through the rotation of the turntable inside the oven. However, existing rotary ovens still generally suffer from uneven heating during actual baking, which has become a key factor restricting the improvement of pastry quality. In terms of heat source layout, traditional rotary ovens mostly use single or symmetrically distributed heating tubes as heat sources. Heat is transferred to the surface of the pastries through air conduction and radiation. However, due to dead zones in the airflow inside the oven, the temperature is higher in areas close to the heat source and lower in areas farther away from the heat source. This results in pastries in different locations having different shades of browning and significant differences in doneness during baking.

[0003] To effectively solve the problem of uneven heating during the baking process in existing rotary ovens, improve the consistency of pastry quality, and meet the high quality requirements of large-scale production, we propose a rotary oven for pastry baking. Utility Model Content

[0023] In use, place the tray containing the pastries on the second turntable 8, open the oven door 4, push the mounting plate 17 onto the first turntable 7, and restrict the position of the mounting plate 17 by the limit strip 16. Then close the oven door 4, start the baking assembly to bake the pastries. At the same time, the drive mechanism drives the first turntable 7 to rotate, which in turn drives the mounting plate 17 to rotate, which in turn drives the tray on the second turntable 8 to rotate. Under the action of the rotation mechanism, the second turntable 8 rotates, which in turn drives the tray to rotate, so that the pastries on the second turntable 8 are heated from all directions. This solves the problem of uneven heating in the baking process of existing rotary ovens, improves the consistency of the quality of finished pastries, and meets the high requirements of large-scale production for pastry quality.

[0024] The drive mechanism includes a motor 6, which is fixedly installed inside the housing 1. A rotating gear 10 is fixedly connected to the output end of the motor 6. A gear ring 11 is fixedly connected to the bottom of the first turntable 7, and the gear ring 11 meshes with the rotating gear 10. Starting the motor 6 drives the rotating gear 10 to rotate, which in turn drives the gear ring 11 to rotate, and the rotation of the gear ring 11 drives the first turntable 7 to rotate.

[0025] The self-rotating mechanism includes a sleeve 19, which is fixedly mounted on a mounting plate 17. A fixing plate 14 is fixedly fitted over the sleeve 19. A fixing rod 24 is rotatably mounted on the mounting plate 17. The sleeve 19 is fitted over the fixing rod 24. Several sets of driving bevel gears 29 are fixedly fitted over the fixing rod 24. Several sets of rotating rods 18 are rotatably mounted on the sleeve 19. A driven bevel gear 28 is fixedly connected to one end of the rotating rod 18 near the fixing rod 24. The driven bevel gear 28 meshes with the driving bevel gear 29. The mounting plate 17... Several sets of positioning rods 20 are fixedly connected to the upper part. A protective cover 21 is fixedly connected to one end of the positioning rod 20 near the sleeve 19. An installation rod 23 is rotatably passed through the protective cover 21. The top of the installation rod 23 is fixedly connected to the bottom of the second turntable 8. A first bevel gear 26 is fixedly connected to the bottom of the installation rod 23. A second bevel gear 27 is fixedly connected to one end of the driven bevel gear 28 away from the fixed rod 24. The second bevel gear 27 meshes with the first bevel gear 26. A fixing mechanism for fixing the position of the fixed rod 24 is installed on the housing 1.

[0026] The fixing mechanism fixes the fixing rod 24. The rotating mounting plate 17 drives the rotating rod 18 to rotate, which in turn drives the driven bevel gear 28 to rotate around the driving bevel gear 29. This causes the driven bevel gear 28 to rotate on its own axis. The driven bevel gear 28 drives the second bevel gear 27 and the first bevel gear 26 to rotate, which in turn drives the mounting rod 23 to rotate. The rotation of the mounting rod 23 causes the second turntable 8 to rotate on its own axis.

[0027] The fixing mechanism includes a connecting rod 12, which is fixedly connected to the bottom of the inner cavity of the housing 1. A circular plate 13 is fixedly connected to the top of the connecting rod 12. Two sets of limiting blocks 15 are fixedly connected to the top of the circular plate 13. A connecting plate 22 is fixedly connected to the bottom of the fixing rod 24. The connecting plate 22 matches the limiting blocks 15.

[0028] After the mounting plate 17 is pushed into the housing 1, the connecting plate 22 is locked between the two sets of limiting blocks 15. The circular plate 13 is fixed to the limiting blocks 15 by the connecting rod 12. The fixing of the limiting blocks 15 fixes the connecting plate 22, which in turn fixes the fixing rod 24.

[0029] The baking components include a partition 25, which is fixedly connected to the inner wall of the box 1. A hot air blower 5 is fixedly installed on the top of the partition 25. A hot air plate 9 is fixedly connected to the inner wall of the box 1. Several sets of ventilation holes are opened on the hot air plate 9. Several sets of heat dissipation holes 2 are opened on the left side of the box 1. The heat dissipation holes 2 correspond to the motor 6.

[0030] The hot air generated by the hot air blower 5 is blown onto the mounting plate 17 through the ventilation holes on the hot air plate 9 to bake the pastries. At the same time, the heat dissipation holes 2 can dissipate heat from the motor 6 to prevent the motor 6 from overheating. A step 3 is fixedly installed on the front side of the housing 1, and the step 3 is provided with a slope. This facilitates pushing the mounting plate 17 into the housing 1.

[0031] Working principle: In use, place the tray containing pastries on the second turntable 8, open the door 4, and push the mounting plate 17 onto the first turntable 7. The position of the mounting plate 17 is restricted by the limiting strip 16. After the mounting plate 17 is pushed into the box 1, the connecting plate 22 is locked between the two sets of limiting blocks 15. The circular plate 13 is fixed to the limiting blocks 15 by the connecting rod 12. The fixing of the limiting blocks 15 fixes the connecting plate 22, which in turn fixes the fixing rod 24. Then the door 4 is closed. Then the hot air blower 5 is turned on. The hot air generated by the hot air blower 5 through the ventilation holes on the hot air plate 9 onto the mounting plate 17 to bake the pastries. At the same time, the motor 6 is started to drive the rotating gear 10 to rotate, which drives the gear ring 11 to rotate. The rotation of the gear ring 11 drives the first turntable 7. The rotation of the mounting plate 17 causes the mounting plate 17 to rotate, which in turn causes the tray on the second turntable 8 to rotate. The fixed rod 24 secures the driving bevel gear 29. The rotating mounting plate 17 drives the rotating rod 18 to rotate, causing the driven bevel gear 28 to rotate around the driving bevel gear 29. This causes the driven bevel gear 28 to rotate, which in turn drives the second bevel gear 27 and the first bevel gear 26 to rotate, which in turn drives the mounting rod 23 to rotate. The rotation of the mounting rod 23 causes the second turntable 8 to rotate, which in turn drives the tray to rotate. This ensures that the pastries on the second turntable 8 are heated evenly, thus solving the problem of uneven heating in existing rotary ovens during baking, improving the consistency of the finished pastry quality, and meeting the high quality requirements of large-scale production. Simultaneously, the heat dissipation holes 2 can dissipate heat from the motor 6, preventing overheating and extending the equipment's lifespan.
