Technical Field
[0001] This utility model relates to the field of food processing technology, specifically to a fermentation box for processing flour-based foods. Background Technology
[0002] In the food processing industry, starter fermentation is a core process that affects the taste, flavor and quality of flour-based foods (such as bread and steamed buns). The post-fermentation processing is crucial for maintaining the stability of starter quality. With the expansion of industrial production scale, flour-based food processing places higher demands on the efficiency, hygiene and quality consistency of starter processing. It is necessary to quickly inhibit yeast activity after fermentation to avoid secondary fermentation, while isolating external microbial contamination and maintaining appropriate moisture and softness of the starter, laying the foundation for subsequent dough kneading and shaping.
[0003] Taking the processing of starter dough in bread making as an example, traditional processes use independent fermentation equipment. After the starter dough has fermented, it needs to be manually transferred to refrigeration equipment for cooling, and then placed in an aerated preservation device to inhibit unwanted bacteria and prevent secondary fermentation. During the transfer, the starter dough is directly exposed to air, making it highly susceptible to contamination by unwanted bacteria, which can lead to off-flavors and spoilage in the bread. Furthermore, traditional equipment lacks coordination; the refrigeration equipment cannot accurately control the temperature, and the aerated equipment cannot operate synchronously with the cooling process. Temperature fluctuations and residual oxygen often result in secondary fermentation of the starter dough, leading to a coarse texture and collapsed appearance in the finished bread, severely impacting product quality and market competitiveness. Therefore, we need to propose a fermentation box for processing flour-based foods. Utility Model Content

Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-5This utility model provides a technical solution: a fermentation box for processing dough-based foods, comprising a first box 1 and a second box 2. The second box 2 is installed on top of the first box 1. The interior of the first box 1 has a hollow groove 3, providing a sealed space for dough fermentation. The hollow groove 3 inside the first box 1 is used to accommodate the dough and supporting components, ensuring that the fermentation process takes place in a stable environment. The second box 2 provides a mounting carrier for the air inflation component, vacuum pump 20, pressure detector 24, and controller 25, realizing the integrated layout of the equipment's functional modules. A cooling component for cooling the interior of the hollow groove 3 is installed on the outside of the first housing 1. One end of the cooling component extends into the interior of the hollow groove 3. The cooling component includes a semiconductor cooler 4, a first air outlet duct 5, and a fan 6. A fixing plate 7 is installed on the outside of the first housing 1. The semiconductor cooler 4 is installed on the outside of the first housing 1 through the fixing plate 7. The fixing plate 7 is used to fix the semiconductor cooler 4 and ensure that the semiconductor cooler 4 is stable in position during equipment operation. After the semiconductor cooler 4 is powered on, one end generates cold energy to provide a cold source for the cooling component, and the heat generated at the other end is dissipated through the heat dissipation fins 8, fan 9, and heat pipe 28 to maintain its stable operation. The hot end of the semiconductor cooler 4 is equipped with heat dissipation fins 8 and fan 9. The heat dissipation fins 8 increase the heat dissipation area of the hot end of the semiconductor cooler 4, accelerate the heat dissipation speed, and ensure the cooling efficiency of the semiconductor cooler 4. When the fan 9 is running, it generates airflow, accelerates the airflow on the surface of the heat dissipation fins 8, and further improves the heat dissipation effect of the hot end of the semiconductor cooler 4. The hot end of the semiconductor cooler 4 is connected to the heat pipe 28. The auxiliary heat dissipation fins 8 and fan 9 conduct and dissipate the heat from the hot end of the thermoelectric cooler 4, maintaining a stable operating temperature. The exhaust end of the fan 6 is connected to the cold end of the thermoelectric cooler 4. When the fan 6 is running, it draws in the cold energy generated by the thermoelectric cooler 4 and delivers it to the first exhaust duct 5, providing power for the transfer of cold energy. One end of the first exhaust duct 5 is connected to the exhaust end of the fan 6, and the other end of the first exhaust duct 5 is connected to the hollow groove 3. Under the action of the fan 6, the first exhaust duct 5 dissipates the cold energy generated by the thermoelectric cooler 4. The cold air is delivered to the hollow groove 3. The valve 10 controls the delivery and amount of cold air in the first air outlet duct 5 by opening or closing and adjusting the opening degree. The surface of the first air outlet duct 5 is equipped with the valve 10. The semiconductor cooler 4 generates cold air, which is delivered to the first air outlet duct 5 by the fan 6. The cold air is then introduced into the hollow groove 3 by the first air outlet duct 5. At the same time, the heat dissipation fins 8 and fan 9 of the hot end of the semiconductor cooler 4 work with the heat dissipation pipe 28 to dissipate heat. The valve 10 controls the delivery of cold air in the first air outlet duct 5, and finally achieves the cooling of the inside of the hollow groove 3.
[0017] The interior of the second chamber 2 contains an aeration assembly for filling the space where the fermented dough is located with nitrogen to isolate oxygen, inhibit bacterial contamination, and assist in terminating secondary fermentation. The aeration assembly includes a nitrogen cylinder 11 and a first gas supply pipe 12. The nitrogen cylinder 11 is located inside the second chamber 2, and the exhaust end of the nitrogen cylinder 11 is connected to one end of the first gas supply pipe 12. The end of the first gas supply pipe 12 away from the nitrogen cylinder 11 passes through the second chamber 2 and extends into the interior of the first chamber 1. A gas leak detector 13 is installed on the surface of the first gas supply pipe 12. Nitrogen is stored in the nitrogen cylinder 11 and transported to the interior of the first chamber 1 through the first gas supply pipe 12. The gas leak detector 13 monitors whether the first gas supply pipe 12 is leaking, thus achieving the filling of nitrogen into the space where the fermented dough is located. The nitrogen cylinder 11 is installed horizontally inside the second chamber 2 to store nitrogen and provide a nitrogen source for the aeration assembly, meeting the need to fill the interior of the first chamber 1 with nitrogen.
[0018] The first housing 1 is equipped with a blowing assembly that works in conjunction with the inflation assembly. One end of the inflation assembly is connected to one end of the blowing assembly. The blowing assembly includes a second air outlet pipe 14 and a jet pipe 15. The second air outlet pipe 14 is installed horizontally inside the first housing 1. The end of the first gas supply pipe 12 away from the nitrogen cylinder 11 is connected to one end of the second air outlet pipe 14. A connecting shaft 16 is installed inside the first housing 1. The other end of the connecting shaft 16 is connected to the surface of the second air outlet pipe 14. The jet pipe 15 is evenly connected to the surface of the second air outlet pipe 14. The second air outlet pipe 14 receives the nitrogen delivered by the first gas supply pipe 12 and sprays it evenly into the space where the dough is located through the jet pipe 15. The connecting shaft 16 fixes the position of the second air outlet pipe 14 to achieve uniform distribution of nitrogen.
[0019] Electric slide rails 17 are symmetrically installed on the inner wall of the first box 1. A support plate 18 is installed inside the first box 1. The surface of the support plate 18 is used to place dough. The position is adjusted by the electric slide rails 17 to provide stable support for dough fermentation. Square grooves 19 are symmetrically opened on one side of the support plate 18. The square grooves 19 are all adapted to the electric slide rails 17. The electric slide rails 17 are controlled by the controller 25 to achieve reciprocating motion, which drives the support plate 18 to move up and down and adjust the position of the dough inside the first box 1.
[0020] The second housing 2 is equipped with a vacuum pump 20, which is controlled by a controller 25 to extract air from the first housing 1 and reduce the air pressure inside the cavity. The suction end of the vacuum pump 20 is connected to a suction pipe 21, which is used to deliver air from the first housing 1 to the vacuum pump 20, providing a channel for the suction process. One end of the suction pipe 21 away from the suction end of the vacuum pump 20 extends into the interior of the first housing 1. The exhaust end of the vacuum pump 20 is connected to an exhaust pipe 22, and the other end of the exhaust pipe 22 extends to the outside of the second housing 2. The exhaust pipe 22 discharges the air extracted from the first housing 1 by the vacuum pump 20 to the outside of the equipment. A filter box 23 is connected between the vacuum pump 20 and the suction pipe 21. The filter box 23 filters the air delivered to the vacuum pump 20 by the suction pipe 21, removes impurities from the air, and protects the vacuum pump 20 from damage.
[0021] The second chamber 2 is equipped with a pressure detector 24 and a controller 25. The pressure detector 24 detects the air pressure inside the first chamber 1 in real time and transmits the detection data to the controller 25 to provide a basis for air pressure regulation. The first chamber 1 is equipped with a vision sensor 26 and a temperature sensor 27. The vision sensor 26 captures images of the fermentation status of the dough inside the first chamber 1 in real time and transmits the image data to the controller 25 to provide a visual basis for judging the fermentation status of the dough. The temperature sensor 27 detects the temperature inside the first chamber 1 in real time and transmits the temperature data to the controller 25 to provide data support for the cooling component to regulate the temperature. The controller 25 is electrically connected to the pressure detector 24, the vision sensor 26, and the temperature sensor 27, respectively. The controller 25 is also electrically connected to the vacuum pump 20, the electric slide rail 17, and the fan 6, respectively.
[0022] After the equipment is started, the controller 25 receives the initial image of the dough from the vision sensor 26, the initial temperature from the temperature sensor 27, and the initial air pressure of the first chamber 1 from the pressure detector 24 to complete the initial monitoring. If the controller 25 needs to adjust the position of the dough, it instructs the electric slide rail 17 to move the support plate 18 adapted through the square groove 19 to adjust the dough to a suitable fermentation position. After the dough fermentation is completed, the controller 25 starts the vacuum pump 20 to draw air from the first chamber 1 through the suction pipe 21. The air is filtered by the filter box 23 and discharged through the exhaust pipe 22. When the pressure detector 24 detects that the air pressure has reached the preset value, the controller 25 stops the vacuum pump 20.
[0023] Subsequently, the controller 25 starts the inflation assembly. Nitrogen from the nitrogen cylinder 11 is delivered to the second air outlet pipe 14 through the first gas supply pipe 12 and the gas leak detector 13 monitors for leaks. It is then evenly sprayed onto the dough through the jet pipe 15. The connecting shaft 16 fixes the second air outlet pipe 14. The inflation stops after the nitrogen concentration reaches the standard. If the temperature sensor 27 detects that the temperature is too high, the controller 25 starts the fan 6, opens the valve 10, and fixes the cooling capacity of the semiconductor cooler 4 with the fixing plate 7. The cooling is delivered to the hollow groove 3 through the fan 6 and the first air outlet pipe 5. The hot end is cooled by the heat dissipation fins 8, the fan 9, and the heat dissipation pipe 28. After the temperature reaches the standard, the fan 6 is stopped, the valve 10 is closed, and the semiconductor cooler 4 is stopped. Throughout the process, the controller 25 receives data from each sensor and adjusts the operation of the components in real time to ensure the stability of the dough post-processing.
