Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing technology, specifically a fermentation temperature control device for making grain pastries. Background Technology
[0002] In the production of grain-based pastries, the fermentation process is extremely sensitive to temperature. A suitable and stable temperature is crucial for ensuring effective fermentation and improving the quality of the final product. Traditional grain-based pastry fermentation relies heavily on ambient temperature, which is difficult to control precisely and is greatly affected by season, region, and diurnal temperature variations. At low temperatures, the fermentation process is slow, taking significantly longer and resulting in low efficiency. Insufficient fermentation can also lead to poor texture and a lack of proper fluffiness and flavor. Conversely, high temperatures can easily cause over-fermentation, leading to sourness and spoilage of the dough, severely impacting the quality of the final product.
[0003] To address these issues, while some fermentation equipment exists on the market, most offer only basic heating and lack the intelligent, real-time adjustment capabilities to adapt to temperature changes, resulting in poor temperature control accuracy. Furthermore, kneading and fermentation typically require separate equipment or locations, making the process cumbersome, increasing the risk of contamination during dough transfer, and adding to labor and time costs. Therefore, developing an integrated fermentation temperature control device that can precisely control temperature, automatically adapt to environmental temperature changes, and also incorporate kneading functions is urgently needed. This is of great significance for improving the efficiency and quality of grain-based pastry production and promoting the development of the pastry industry. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0025] This utility model provides an improved fermentation temperature control device for making grain-based pastries. The technical solution of this utility model is as follows:
[0026] like Figure 1 - Figure 6 As shown, a fermentation temperature control device for making grain pastries includes a first cavity 1, a transparent cavity 2 fixedly connected to the upper end of the first cavity 1, a second cavity 3 fixedly connected to the upper end of the transparent cavity 2, an annular plate 4 fixedly connected to the upper end of the second cavity 3, two symmetrically arranged limiting grooves 5 opened at the upper end of the annular plate 4, a first conductive hole 6 opened at the upper end of the annular plate 4, a second conductive hole 7 opened at the upper end of the annular plate 4, a first conductive block 8 fixedly connected to the inner wall of the first conductive hole 6, a second conductive block 9 fixedly connected to the inner wall of the second conductive hole 7, a first wire 10 fixedly connected to the lower end of the first conductive block 8, a second wire 11 fixedly connected to the lower end of the second conductive block 9, an annular heater 12 fixedly connected to the inner wall of the first cavity 1, the first wire 10 fixedly connected to the positive electrode of the annular heater 12, and the second wire 11 fixedly connected to the negative electrode of the annular heater 12.
[0027] Furthermore, a cover plate 13 is provided at the upper end of the annular plate 4, and a rotating rod 14 is rotatably connected to the lower end of the cover plate 13. Multiple sets of parallel kneading rods 15 are fixedly connected to the surface of the rotating rod 14. A servo motor 16 is fixedly connected to the upper end of the cover plate 13. The output end of the servo motor 16 passes through the upper end of the cover plate 13 and is fixedly connected to the upper end of the rotating rod 14. Two limiting blocks 17 that match the limiting groove 5 are fixedly connected to the lower end of the cover plate 13. A protective box 18 is fixedly connected to the upper end of the cover plate 13. A temperature conducting pipe 19 is fixedly connected to the upper end of the cover plate 13. One end of the temperature conducting pipe 19 passes through the upper end of the cover plate 13 and extends into the interior. A cylinder 20 is provided inside the protective box 18. The cover plate 13 is provided at the upper end of the annular plate 4. The cover plate 13 is connected to the kneading rods 15 through the rotating rod 14 and is driven by the servo motor 16. This design enables the device to not only have fermentation temperature control but also knead dough, integrating kneading and fermentation functions together. This reduces the footprint of the equipment, improves the efficiency of grain pastry production, and allows the kneading process to be completed inside the device, avoiding potential contamination during dough transfer.
[0028] Furthermore, the other end of the temperature-conducting tube 19 is fixedly connected to the left end of the cylinder 20. A piston plate 21 is slidably connected to the inner wall of the cylinder 20. Silicone oil 22 is provided on the left side of the piston plate 21. A round rod 23 is fixedly connected to the right end of the piston plate 21. The right end of the round rod 23 penetrates the inner wall of the cylinder 20 and extends to the outside. A return spring 24 is sleeved on the surface of the round rod 23. A first conductive sheet 25 is fixedly connected to the right end of the round rod 23. There are two symmetrically arranged second conductive sheets 27 on the left side of the first conductive sheet 25. A plastic rod 26 is fixedly connected to the left end of each of the two second conductive sheets 27. The other end of the plastic rod 26 is fixedly connected to the right end of the cylinder 20. A temperature control structure consisting of a protective box 18, a temperature-conducting tube 19, a cylinder 20, a piston plate 21, silicone oil 22, a round rod 23, a return spring 24, a first conductive sheet 25, and a second conductive sheet 27 is provided on the cover plate 13. This structure utilizes the thermal expansion and contraction properties of silicone oil 22. By moving the piston plate 21, the first conductive sheet 25 is brought into contact with or separated from the second conductive sheet 27, thereby achieving automatic control of the circuit of the ring heater 12. This allows for precise control of the fermentation temperature, ensuring the stability and consistency of the fermentation effect.
[0029] Furthermore, a third conductive block 28 and a fourth conductive block 29 are fixedly connected to the upper end of the cover plate 13. A third wire 30 is fixedly connected to the surface of the second conductive piece 27 on the left side. The other end of the third wire 30 is fixedly connected to the side wall of the third conductive block 28. The cover plate 13 is equipped with the third conductive block 28 and the fourth conductive block 29, and the second conductive piece 27 on the left side is connected to the third conductive block 28 through the third wire 30. This design makes the circuit connection between the temperature control structure and the ring heater 12 more reasonable and stable, ensuring that the temperature control signal can be accurately transmitted to the ring heater 12, thereby achieving effective control of the heating process.
[0030] Furthermore, the lower end of the third conductive block 28 penetrates the upper end of the cover plate 13 and extends downwards, matching the inner wall of the second conductive hole 7. Similarly, the lower end of the fourth conductive block 29 penetrates the upper end of the cover plate 13 and extends downwards, matching the inner wall of the first conductive hole 6. The lower ends of the third conductive block 28 and the fourth conductive block 29 respectively match the inner walls of the second conductive hole 7 and the first conductive hole 6. This matching design ensures a tight and reliable circuit connection between the cover plate 13 and the annular plate 4, preventing circuit failures caused by loose connections and improving the stability and reliability of the device.
[0031] Furthermore, a fourth wire 31 is fixedly connected to the side wall of the fourth conductive block 29, and a fifth wire 32 is fixedly connected to the surface of the second conductive piece 27 on the right side. The other ends of the fourth wire 31 and the fifth wire 32 are fixedly connected to the same plug 33. The fourth conductive block 29 is connected to the same plug 33 via the fourth wire 31, and the second conductive piece 27 on the right side is connected to the same plug 33 via the fifth wire 32. This unified power connection method makes the power supply of the device simpler and more convenient, facilitating operation and maintenance, while also reducing the complexity of circuit wiring and lowering the probability of failure.
[0032] Furthermore, one end of the return spring 24 is fixedly connected to one end of the piston plate 21, and the other end of the return spring 24 is fixedly connected to the inner wall of the cylinder 20. The return spring 24 can promptly pull the piston plate 21 back to its initial position when the silicone oil 22 contracts, ensuring that the temperature control structure can quickly respond to temperature changes, allowing the annular heater 12 to turn on or off in a timely manner, thus improving the sensitivity and accuracy of temperature control.
[0033] Working principle: When plug 33 is connected to the power supply, the current flows sequentially through the fourth wire 31 and the fourth conductive block 29 into the first conductive hole 6, through the first conductive block 8 and the first wire 10 to reach the positive terminal of the annular heater 12, flows out from the negative terminal of the annular heater 12, and then through the second wire 11, the second conductive block 9, the third conductive block 28 and the third wire 30 to form a complete circuit. At this time, the annular heater 12 is started and begins to provide heat for the fermentation of the grain dough.
[0034] When the ambient temperature drops, the temperature-conducting tube 19 senses the low temperature, and the silicone oil 22 inside it contracts upon cooling. Under the elastic force of the return spring 24, the piston plate 21 moves to the left, causing the connected rod 23 and the first conductive plate 25 at the right end of the rod 23 to move to the left. When the first conductive plate 25 contacts the second conductive plate 27 on the left, the circuit is connected, the current flows normally, and the annular heater 12 continues to maintain a heating state, thus maintaining a suitable fermentation temperature.
[0035] If the ambient temperature rises, the silicone oil 22 expands due to heat, pushing the piston plate 21 to slide to the right, and the round rod 23 and the first conductive plate 25 also move to the right. Until the first conductive plate 25 contacts the second conductive plate 27 on the right, at which point the current forms a short circuit through the fifth wire 32 and the fourth wire 31, the circuit of the annular heater 12 is cut off, and heating stops.
[0036] If kneading is required, the servo motor 16 on the cover plate 13 is turned on. The output of the servo motor 16 drives the rotating rod 14 to rotate, and the multiple sets of parallel kneading rods 15 fixed on the surface of the rotating rod 14 rotate accordingly to stir and knead the dough. At the same time, the limiting block 17 at the lower end of the cover plate 13 cooperates with the limiting groove 5 on the annular plate 4 to ensure the stability of the cover plate 13 during the kneading process and improve the kneading effect.
[0037] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
