[0005] It further includes a humidification chamber fixedly installed at the bottom end of the fermentation chamber. Both sides of the top end of the humidification chamber are provided with pipelines. The two pipelines respectively penetrate through the upper lapping bodies in sequence until they extend into the adjusting cavities at the top ends of the lapping bodies. A docking device is arranged in each of the plurality of adjusting cavities. The docking device is used to connect or block the pipeline with the air vent. The bottom end of the left pipeline is communicated with an air pump, and the exhaust end of the air pump extends deep into the inner bottom end of the humidification chamber.

[0006] In one embodiment, the docking device includes a docking pipe communicated with the pipeline located in the adjusting cavity. An air vent cover is connected to the end of the docking pipe and covers the air vent. An electromagnetic valve is fixedly installed on the docking pipe.

[0007] In one embodiment, a trigger ventilation switch is provided in the adjustment cavity. The trigger ventilation switch includes a sealing plate. The sealing plate is disposed at the port of the ventilation hood. One side of the sealing plate contacts the hood opening of the ventilation hood, and the other side of the sealing plate contacts the inner wall of the adjustment cavity. An interface is formed on the sealing plate, and the interface is docked and communicated with the ventilation port.

[0008] Two support rods are fixedly connected to the bottom of the sealing plate. The two support rods penetrate through the overlapping body and extend into the docking opening. The bottom of the two support rods is fixedly connected with a trigger plate. The front end of the trigger plate has a guiding surface. The bottom of the trigger plate is placed on the top edge of the placing tray.

[0009] In one embodiment, overlapping grooves are formed at the edges on both sides of the top of the placing tray. The trigger plate is placed in the overlapping grooves, and a pressure sensor is fixedly installed at the bottom of the trigger plate.

[0010] In one embodiment, a support spring is sleeved on the surface of the support rod. The two ends of the support spring are respectively fixedly connected to the bottom end of the inner wall of the adjustment cavity and the sealing plate.

[0011] In one embodiment, guiding inclined surfaces are formed at both the front and rear ends of the trigger plate.

[0012] In one embodiment, a first support body and two second support bodies are provided at the bottom of multiple placing trays. The first support body is fixedly connected between the two overlapping bodies and the inner wall of the fermentation box, and the two second support bodies are fixedly connected between the front sides of the two overlapping bodies and the inner wall of the fermentation box.

[0013] In one embodiment, the second support body has an installation cavity. A placing rod is rotatably connected between the installation cavity and the two second support bodies. The placing plate is placed between the two placing rods.

[0014] In one embodiment, two support shafts are rotatably connected to the top of the second support body. Limit columns are fixedly connected to the surfaces of the two support shafts.

[0015] In one embodiment, a rapid fermentation method for bread dough, according to the rapid fermentation device for bread dough as claimed in the claims, is characterized by comprising the following steps:

[0016] Step 1, installing the placing tray: Open the box door, and insert the placing tray with the dough placed thereon into the two docking openings at the same height.

[0017] Step 2, humidification: close the box door, start the docking device in the adjustment chamber where the shelf tray is located, start the air pump, and the air pump sucks air from the pipe connected to the air pump, forming a negative pressure in the pipe. The air above the shelf tray will enter the pipe through the vent and the docking device. The air pump discharges the sucked gas into the water stored in the humidification chamber. The gas that has come into contact with the water passes through the water and enters the pipe on the right. The humidified water passes through the docking device and the vent in turn and enters the space above the shelf tray for humidification. The air above the shelf tray is circulated and humidified.

[0018] Step 3: Fermentation: The dough will ferment in the humidified space until fermentation is completed, open the door and take out the shelf tray.

[0019] The above-mentioned rapid fermentation device and method for bread dough can quickly divert the humidified gas to the top of the shelf tray during the entire humidification process, thereby directly humidifying the air above the shelf tray, and during the humidification process, the air above the shelf tray is circulated and humidified, which is beneficial to quickly humidify the environment around the dough above the shelf tray, solves the problem of needing to diffuse the humidified gas from the bottom of the fermentation box to the top of the shelf tray layer by layer, and is beneficial to speed up the humidification speed. In the humidification process, through the setting of the docking device, the humidified airflow can be diverted only to the position where the shelf tray is installed according to the installation of the shelf tray, and the humidification position is clear.

[0020] After the trigger plate is lifted up, when the overlapping groove is aligned with the trigger surface, the trigger plate will be inserted into the overlapping groove, and the pressure sensor will contact the bottom surface of the overlapping groove. The pressure sensor detects the pressure and triggers the solenoid valve next to it to connect the docking pipe and cooperate with the docking port to achieve connection. Therefore, on the one hand, the installation position of the shelf plate is positioned, and on the other hand, the docking device is triggered to connect the pipeline and the vent, achieving double protection. After the installation of the shelf plate is automatically identified, the docking device connects the pipeline and the vent, achieving double protection of mechanical control of the sealing plate and sensor control of the pressure sensor, avoiding the situation where the pipeline and the vent are connected for no reason.

[0021] The first support body, the second support body, the two overlapping bodies and the shelf tray form an isolation layer as a whole, which divides the space in the fermentation box, so that the space above each shelf tray exists independently, and the space between adjacent shelf trays is completely isolated, which is beneficial to concentrate the circulating humidified gas in a limited space, which is beneficial to quickly humidify the area near the dough.

[0040] The following is combined with Figures 1 - 10Describe a rapid fermentation device and method for bread dough of the present invention.

[0041] As Figures 2 to 10 shown, in one embodiment, a rapid fermentation device for bread dough includes a fermentation chamber 1, a chamber door 2 is hinged to the front of the fermentation chamber 1, lap joints 3 are provided on both sides of the inner wall of the fermentation chamber 1, a plurality of docking ports 4 are opened on the side walls of the lap joints 3, a plurality of adjustment chambers 5 are opened inside the lap joints 3, the plurality of adjustment chambers 5 are respectively arranged above the plurality of docking ports 4, air vents 6 are opened on the inner side walls of the adjustment chambers 5, and a shelving tray 7 is placed in the docking ports 4 on the two lap joints 3 at the same height;

[0042] It further includes a humidification chamber 8, the humidification chamber 8 is fixedly installed at the bottom end of the fermentation chamber 1, two pipes 9 are provided on both sides of the top end of the humidification chamber 8, the two pipes 9 respectively penetrate through the upper lap joints 3 in sequence until they extend into the adjustment chambers 5 at the top of the lap joints, a docking device is provided in each of the plurality of adjustment chambers 5, and the docking device is used to connect or block the pipe 9 with the air vent 6, wherein the bottom end of the left pipe 9 is communicated with an air pump 10, and the exhaust end of the air pump 10 extends deep into the inner bottom end of the humidification chamber 8.

[0043] It should be understood that during the fermentation process, the chamber door 2 is opened, a plurality of shelving trays 7 are installed in the fermentation chamber 1 and arranged at different heights, then the chamber door 2 is closed, the docking device in the adjustment chamber 5 where the shelving tray 7 is installed is activated, the air pump 10 is activated, the air pump 10 sucks air from the pipe 9 communicated with it, a negative pressure is formed in the pipe 9, the air above the shelving tray 7 will enter the pipe 9 through the air vent 6 and the docking device, the air pump 10 discharges the inhaled gas into the water stored in the humidification chamber 8, the gas after contacting the water enters the right pipe 9 through the water, and the humidified water enters the space above the shelving tray 7 through the docking device and the air vent 6 in sequence for humidification, and the air above the shelving tray 7 is circulated and humidified;

[0044] During the entire humidification process, the humidified gas can be quickly split and flow to the space above the shelving tray 7, thereby directly humidifying the air above the shelving tray 7, and during the humidification process, the air above the shelving tray 7 is circulated and humidified, which is beneficial to quickly humidify the environment around the dough on the shelving tray 7, solves the problem that the humidified gas needs to be diffused layer by layer from the bottom end of the fermentation chamber 1 to the space above the shelving tray 7, and is beneficial to accelerating the humidification speed;

[0045] And during the humidification process, through the setting of the docking device, according to the installation of the shelving tray 7, only the humidified air flow can be split and flow to the position where the shelving tray 7 is located, and the humidification position is clear.

[0046] As Figure 5 、 Figure 6 、 Figure 8 andFigure 9 As shown, in one embodiment, the docking device includes a docking pipe 11. The docking pipe 11 is communicated with a pipe 9 located in the adjustment chamber 5. An air vent hood 12 is communicated with the end of the docking pipe 11. The air vent hood 12 covers the air vent 6. A solenoid valve 13 is fixedly installed on the docking pipe 11. It should be understood that when it is necessary to humidify the space above the shelving tray 7, the solenoid valve 13 on the docking pipe 11 close to the upper part of the shelving tray 7 is opened. Then, the air pump 10 is started. The air pump 10 sucks air from the pipe 9 communicated with the air pump 10, and a negative pressure is formed in the pipe 9. The air above the shelving tray 7 will enter the pipe 9 through the air vent 6 and the docking device. The air pump 10 discharges the inhaled gas into the water stored in the humidification chamber 8. The gas after contacting the water enters the pipe 9 on the right side through the water. The humidified water enters the space above the shelving tray 7 through the docking pipe 11, the air vent hood 12 and the air vent 6 in sequence, and the humidified gas is guided to the space where the dough is placed, realizing purposeful humidification.

[0047] As Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, in one embodiment, a trigger ventilation switch is arranged in the adjustment chamber 5. The trigger ventilation switch includes a sealing plate 14. The sealing plate 14 is arranged at the port of the air vent hood 12. One side of the sealing plate 14 contacts the hood opening of the air vent hood 12, and the other side of the sealing plate 14 contacts the inner wall of the adjustment chamber 5. A docking port 15 is opened on the sealing plate 14, and the docking port 15 is docked and communicated with the air vent 6;

[0048] Two support rods 16 are fixedly connected to the bottom of the sealing plate 14. The two support rods 16 penetrate through the overlapping body 3 and then extend into the docking opening 4. The bottom of the two support rods 16 is fixedly connected with a trigger plate 17. The bottom of the trigger plate 17 is placed on the top edge of the shelving tray 7. It should be understood that during the process of inserting the shelving tray 7 into the docking opening 4, the shelving tray 7 will push the trigger plate 17 upward. The trigger plate 17 supports the sealing plate 14 through the support rods 16, so that the docking port 15 is aligned with the air vent 6, realizing docking and communication. When the shelving tray 7 is not installed, the air vent 6 is always blocked, preventing the humidified gas from being drained without reason and concentrating the humidified gas at the position where the dough is located.

[0049] As Figure 1 , Figure 2 , Figure 9 and Figure 10As shown, in one embodiment, overlapping grooves 18 are provided at the edges of both sides of the top of the shelf tray 7, the trigger plate 17 is mounted in the overlapping grooves 18, and a pressure sensor 26 is fixedly installed at the bottom of the trigger plate 17. It should be understood that after the trigger plate 17 is lifted up, when the overlapping grooves 18 are aligned with the trigger plate 17, the trigger plate 17 will be inserted into the overlapping grooves 18, and the pressure sensor 26 will contact the inner bottom surface of the overlapping grooves 18. The pressure sensor 26 detects the pressure and triggers the solenoid valve 13 on the side to connect the docking pipe 11, and cooperate with the docking port 15 to achieve communication. Therefore, on the one hand, the installation position of the shelf tray 7 is positioned, and on the other hand, the docking device is triggered to connect the pipeline 9 with the vent 6, achieving double protection. After the installation of the shelf tray 7 is automatically identified, the docking device connects the pipeline 9 with the vent 6, achieving double protection of the mechanical control of the sealing plate 14 and the sensor control of the pressure sensor 26, avoiding the situation where the pipeline 9 and the vent 6 are connected without reason.

[0050] like Figure 5 and Figure 6 As shown, in one embodiment, a support spring 19 is sleeved on the surface of the support rod 16, and the two ends of the support spring 19 are respectively fixedly connected to the bottom end of the inner wall of the adjustment chamber 5 and the sealing plate 14. It should be understood that by providing the support spring 19, elastic support is provided for the sealing plate 14, and when the overlapping groove 18 and the trigger plate 17 are connected, the support spring 19 can be pulled to pull the trigger plate 17 into the overlapping groove 18 to form a snap connection, thereby positioning the installation position of the shelf plate 7, which is conducive to maintaining the stability of the shelf plate 7.

[0051] like Figure 8 As shown, in one embodiment, both front and rear ends of the trigger plate 17 are provided with guiding slopes 1701 . It should be understood that when the trigger plate 17 enters the overlapping groove 18 , under the guidance of the guiding slopes 1701 , the trigger plate 17 is facilitated to be smoothly inserted into the overlapping groove 18 .

[0052] As shown in the figure, in one embodiment, the bottom of the plurality of shelf trays 7 are provided with a first support body 20 and two second support bodies 21, the first support body 20 is fixedly connected between the two overlapping bodies 3 and the inner wall of the fermentation box 1, and the two second support bodies 21 are fixedly connected between the front sides of the two overlapping bodies 3 and the inner wall of the fermentation box 1. It should be understood that after the shelf tray 7 is installed, the first support body 20, the second support body 21, the two overlapping bodies 3 and the shelf tray 7 as a whole form an isolation layer, which separates the space in the fermentation box 1, so that the space above each shelf tray 7 exists independently, and the space between adjacent shelf trays 7 is completely isolated, which is conducive to concentrating the circulating humidified gas in a limited space, and is conducive to rapid humidification near the dough.

[0053] like Figure 2 ,Figure 3 and Figure 7 As shown in Figure 7 , in one embodiment, the second support 21 has a mounting cavity 22. A placing rod 23 is rotatably connected both inside the mounting cavity 22 and between two second supports 21. The placing tray 7 is placed on the two placing rods 23. It should be understood that by providing the placing rod 23, the function of supporting the bottom of the placing tray 7 is achieved.

[0054] As Figure 2 and Figure 3 As shown in Figure 3 , in one embodiment, two support shafts 24 are rotatably connected to the top of the second support 21. Limit posts 25 are fixedly connected to the surfaces of the two support shafts 24. It should be understood that by providing the limit posts 25, the placing tray 7 is guided and limited before entering the docking interface 4, so that the placing tray 7 is aligned with the docking interface 4, which is beneficial for the placing tray 7 to smoothly enter the docking interface 4 and determines the edge position in contact with the trigger plate 17, providing favorable conditions for the docking of the trigger plate 17 and the docking groove 18.

[0055] As Figure 1 As shown in Figure 1 , in one embodiment, a method for rapid fermentation of bread dough includes the following steps:

[0056] Step 1, install the placing tray 7: Open the box door 2 and insert the placing tray 7 with the dough into the two docking interfaces 4 at the same height.

[0057] Step 2, humidify: Close the box door 2, start the docking device in the adjustment cavity 5 where the placing tray 7 is located, start the air pump 10. The air pump 10 sucks air from the pipeline 9 communicated with the air pump 10, and a negative pressure is formed in the pipeline 9. The air above the placing tray 7 will enter the pipeline 9 through the ventilation port 6 and the docking device. The air pump 10 discharges the inhaled gas into the water stored in the humidification chamber 8. The gas after contacting the water enters the right pipeline 9 through the water. The humidified water enters the space above the placing tray 7 through the docking device and the ventilation port 6 in sequence for humidification, and the air above the placing tray 7 is circulated and humidified.

[0058] Step 3, ferment: The dough will ferment in the humidified space until the fermentation is completed. Open the box door 2 and take out the placing tray 7.

[0059] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described.
