Description

Technical Field

[0001] This utility model relates to the field of vinegar brewing technology, specifically a high-efficiency mixing device for raw materials used in vinegar fermentation. Background Technology

[0002] Vinegar is an acidic condiment. Depending on the production method, there are brewed vinegar and artificially synthesized vinegar. Brewed vinegar is made by fermenting starchy grains, sugars, and edible alcohol through microorganisms. Vinegar made by mixing koji involves mixing koji, yeast, and yeast liquid into the raw materials and stirring 2 to 3 times to make them uniform. The device used for mixing koji is called a koji mixing device.

[0003] However, current mixing equipment suffers from insufficient intelligence in material handling, as its stirring speed cannot be dynamically adjusted according to changes in the material's state. During the mixing stage, a higher speed is required for thorough mixing; however, during fermentation, the speed must be reduced to avoid mechanical shearing damage to yeast activity. Existing solutions rely solely on manual experience for staged speed adjustments. This crude control method not only leads to unstable mixing and fermentation quality but also results in significant energy waste. Therefore, this invention provides a high-efficiency mixing device for vinegar fermentation raw materials to address the aforementioned problems. Utility Model Content

The outer wall of the main stirring blade has multiple pressure relief grooves arranged linearly and are inclined. The sliding rod is slidably connected to the inner wall of the pressure relief groove near the mounting sleeve. The two ends of the electric telescopic rod are fixedly connected to the wall surfaces opposite to the sliding rod and the mounting sleeve.

[0010] As a further embodiment of this utility model, the conveying assembly includes a main conveying pipe, a gas collecting pipe, and an exhaust pipe. The main conveying pipe is installed at the axial position of the inner wall of the stirring shaft. One end of the gas collecting pipe is installed on the inner wall of the main stirring blade, and the other end of the gas collecting pipe passes through the mounting sleeve and the stirring shaft and is connected to the inner wall of the main conveying pipe. Both ends of the exhaust pipe are connected to the pressure-bearing sleeve and the gas collecting pipe, respectively.

When this utility model is used, the angle of the main stirring blade can be dynamically adjusted according to the pressure of the material at different stages through the set control components and rotation components. During the mixing stage, the angle of the main stirring blade is increased to facilitate the exchange of materials at different liquid levels and improve the mixing effect. During the fermentation stage, the angle of the main stirring blade is decreased to avoid excessive shear force that could affect the survival of yeast and thus affect the fermentation effect.

[0031] 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.

[0032] Please see Figure 1 and Figure 3 In this embodiment of the present invention, a high-efficiency mixing device for raw materials for vinegar fermentation includes a fermentation tank 10. A support leg 12 is installed at the bottom of the fermentation tank 10, and a drive motor 20 is installed at the top of the fermentation tank 10. A stirring shaft 21 for transmission is installed at the output end of the drive motor 20. A stirring component for mixing and fermenting materials is installed on the stirring shaft 21. A feed inlet 11 and a discharge inlet 13 for feeding and discharging materials are respectively installed at the top and bottom of the fermentation tank 10. A solenoid valve for controlling the opening and closing is installed in the discharge inlet 13. Raw materials are added to the inner wall of the fermentation tank 10 through the feed inlet 11. The stirring shaft 21 is driven to rotate by starting the drive motor 20. The rotation of the stirring shaft 21 can mix and ferment the raw materials through the stirring component on it. After processing, the solenoid valve can be opened to discharge the raw materials.

[0033] The stirring assembly includes mounting sleeves 23 linearly arranged on the outer wall of a stirring shaft 21. A connector 26 is fixedly connected to one end of the mounting sleeve 23 on the outer wall of the stirring shaft 21. The connector 26 consists of a connecting ring fixedly connected to the outer wall of the stirring shaft 21 and arc-shaped mounting blocks installed at both ends of the connecting ring. The mounting blocks are connected to the mounting sleeve 23 by bolts. Multiple main stirring blades 24 arranged in a circular pattern are rotatably connected to the outer wall of the mounting sleeve 23. Multiple rotating seats 80 arranged in a circular pattern are fixedly connected to the outer wall of the mounting sleeve 23. The inner wall of the rotating seat 80 has a through rotating hole, and the inner wall of the rotating hole is rotatably connected to... There is a rotating pin 82. The main stirring blade 24 is fixedly connected to a rotating block 81 near the end of the mounting sleeve 23. The rotating block 81 is fixedly connected to the outer wall of the rotating pin 82. When the main stirring blade 24 rotates, it drives the rotating pin 82 to rotate in the rotating hole in the rotating seat 80 through the rotating block 81. The main stirring blade 24 rotates in the vertical direction around the axis of the rotating pin 82. The outer wall of the mounting sleeve 23 is equipped with a rotating assembly for driving the main stirring blade 24 to rotate. The angle of the mounting sleeve 23 is adjusted by the rotating assembly, so that the raw materials can be rotated to different angles in different mixed fermentation states to adapt to the processing of the raw materials.

[0034] The main stirring blade 24 is equipped with a pressure-bearing component that generates air pressure changes by extruding materials on one side of the rotation direction. When the main stirring blade 24 rotates to mix the materials, the pressure-bearing component is subjected to the extrusion of the materials.

[0035] A partition 16 for matching installation is installed at the bottom of the inner wall of the fermentation tank 10. An overflow groove for liquid to pass through is opened on the outer wall of the partition 16. A control box 40 is installed at the bottom of the partition 16. A control component for adjusting the output power of the rotating component and the drive motor 20 is installed in the control box 40. A conveying component connected to the control box 40 and the pressure-bearing component is installed in the stirring shaft 21. The air pressure generated at the pressure-bearing component is conveyed to the control component through the conveying component. The control component adjusts the drive motor 20 and the rotating component, and then adjusts the rotation speed and angle of the main stirring blade 24 to adapt to different mixing states of materials.

[0036] For more details, please refer to Figure 2The fermentation tank 10 has an annular temperature control sleeve 30 fitted onto its outer wall. The temperature control sleeve 30 has a cavity inside. A second vent 34, connected to the cavity, is installed on one side of the top of the temperature control sleeve 30. Support plates 31 are bolted to both sides of the outer wall of the temperature control sleeve 30. A cold air fan 32 and a hot air fan 33 are respectively installed on the top of the support plates 31. The cold air fan 32 is located on the top support plate 31. The output ends of both the hot air fan 33 and the cold air fan 32 are connected to the cavity via pipes. Specifically, when the raw materials are in the mixing stage, the hot air fan 33 is turned on to deliver hot air to the cavity. The inner wall of the temperature control sleeve 30 is heated by hot air, which is lighter than air. The hot air rises upon entering the sleeve and is then expelled through the second exhaust port 34. This hot air heats the materials in the fermentation chamber 10, improving mixing efficiency. When the materials are in the fermentation stage, the cooler 32 is turned on. The cooler delivers cooling air to the cavity inside the temperature control sleeve 30. Since the cold air is heavier than air, it sinks and fills the cavity in the temperature control sleeve 30, thus cooling the materials and preventing excessively high temperatures from killing the yeast and affecting the fermentation effect.

[0037] See Figure 7 and Figure 8 The control assembly includes a conductive sleeve 42 and a control box 70. The conductive sleeve 42 is installed at both ends of the inner top wall of the control box 40. A mounting ring 41 is fitted onto the outer wall of the conductive sleeve 42 and is fixedly connected to the inner top wall of the control box 40. The conductive sleeve 42 is filled with an electrolyte solution. A negative electrode plate 43 and a positive electrode plate 44 are slidably connected to both ends of the conductive sleeve 42 via rods. The negative electrode plate 43 and the positive electrode plate 44 form a closed circuit through the conductive sleeve 42 and the internal electrolyte solution. The control box 70 is fixedly connected to both ends of the inner bottom wall of the control box 40. A fixed disk 71 is fixedly connected to the middle of the inner wall of the control box 70. The fixed disk 71 is slidably connected along its axis. A connecting rod 74 is provided, with a second piston plate 72 and a third piston plate 73 fixedly connected to its two ends respectively. The top of the control box 70 is equipped with a second piston plate 72 that communicates with the inner wall of the conductive sleeve 42. When a change in air pressure occurs in the control box 70, gas can enter between the fixed plate 71 and the third piston plate 73 and compress the third piston plate 73. The third piston plate 73 is compressed and moves downward, which in turn drives the second piston plate 72 to move downward through the connecting rod 74, thereby reducing the air pressure in the conductive sleeve 42. The negative electrode plate 43 and the positive electrode plate 44 move towards each other through the rod, reducing the distance between the negative electrode plate 43 and the positive electrode plate 44 and reducing the resistance between them.

[0038] See Figure 6The pressure-bearing assembly includes a pressure-bearing sleeve 60, a pressure-bearing membrane 61, and a first piston plate 62. The pressure-bearing sleeve 60 is installed on one side of the main stirring blade 24 in the direction of rotation. An air chamber is opened inside the pressure-bearing sleeve 60. The first piston plate 62 is slidably connected to the inner wall of the air chamber on the pressure-bearing sleeve 60. The first piston plate 62 can adjust the gas in the air chamber by moving within the air chamber. The pressure-bearing membrane 61 is installed at one end of the pressure-bearing sleeve 60. The pressure-bearing sleeve 60 is concave and elastic. When the pressure-bearing sleeve 60 rotates with the main stirring blade 24, the pressure-bearing membrane 61 can be deformed towards the first piston plate 62 by the pressure of the material. The first piston plate 62 slides within the pressure-bearing sleeve 60 due to the pressure of the deformed pressure-bearing membrane 61.

[0039] See Figure 5 The rotating assembly includes a sliding rod 83 and an electrically driven telescopic rod 84. The sliding rod 83 is electrically driven. The negative plate 43 and the positive plate 44 are connected in series with the circuit of the sliding rod 83 in the same path. When the resistance at the negative plate 43 and the positive plate 44 changes, the current in the circuit of the sliding rod 83 changes accordingly, thus changing the telescopic amount at the sliding rod 83. The outer wall of the main stirring blade 24 has multiple linearly arranged pressure relief grooves 25, which are inclined. The sliding rod 83 is slidably connected to the side near the mounting sleeve 23. The inner wall of the pressure relief groove 25 has an electric telescopic rod 84 with both ends fixedly connected to the opposite wall surfaces of the sliding rod 83 and the mounting sleeve 23. When the electric telescopic rod 84 extends or retracts, it can drive the sliding rod 83 to move closer to the mounting sleeve 23. The sliding rod 83 is limited in its sliding within the pressure relief groove 25. The inclined design of the pressure relief groove 25 allows the main stirring blade 24 to rotate through the vertical displacement of the sliding rod 83. Thus, the angle of the main stirring blade 24 can be adjusted by extending or retracting the electric telescopic rod 84.

[0040] See Figure 4 , Figure 6 and Figure 7 The conveying assembly includes a main conveying pipe 50, a gas collecting pipe 51, and an exhaust pipe 52. The main conveying pipe 50 is installed on the inner wall of the stirring shaft 21 at the axial position. The gas collecting pipe 51 is a flexible hose. One end of the gas collecting pipe 51 is installed on the inner wall of the main stirring blade 24, and the other end of the gas collecting pipe 51 passes through the mounting sleeve 23 and the stirring shaft 21 and is connected to the inner wall of the main conveying pipe 50. The two ends of the exhaust pipe 52 are connected to the pressure-bearing sleeve 60 and the gas collecting pipe 51, respectively. When the first piston plate 62 moves and generates a change in air pressure, the gas at the bottom of the pressure-bearing sleeve 60 can be conveyed to the inner wall of the gas collecting pipe 51 through the exhaust pipe 52, and then conveyed to the inner wall of the main conveying pipe 50 through the gas collecting pipe 51.

[0041] The conveying assembly also includes a connecting pipe 53 and a diverting pipe 54. The connecting pipe 53 is fixedly connected to the bottom inner wall of the control box 40. The bottom end of the main conveying pipe 50 passes through the stirring shaft 21 and the control box 40 and is connected to the connecting pipe 53. The diverting pipe 54 is fixedly connected to both ends of the connecting pipe 53 and is connected to the bottom of the control box 70. The connection between the diverting pipe 54 and the control box 70 is located between the fixed plate 71 and the third piston plate 73. When gas enters the inner wall of the main conveying pipe 50, it can be conveyed through the connecting pipe 53 and the diverting pipe 54 to the fixed plate 71 and the third piston plate 73 on the control box 70, which can squeeze the third piston plate 73 and drive the third piston plate 73 to slide.

[0042] For more details, please refer to Figure 3 A fixing ring is installed on the top of the inner wall of the fermentation tank 10. Rotating door plates 14 are rotatably connected to the inner rings on both sides of the fixing ring. The rotating door plates 14 are driven by electricity to rotate and divide the internal space of the fermentation tank 10 into two chambers: a temporary storage chamber at the top and a fermentation chamber at the bottom. Multiple auxiliary stirring blades 22 arranged in a circle are fixedly connected to the outside of the stirring shaft 21 at the temporary storage chamber. The fermentation tank 10 has a first exhaust port 15 for gas discharge on one side of the temporary storage chamber. Specifically, when the material enters the fermentation tank 10 through the feed inlet 11, it can be stored in the temporary storage chamber. At this time, the auxiliary stirring blades 22 rotate with the stirring shaft 21 to premix the material and preheat the material in the temporary storage chamber by the heat generated by the material in the fermentation tank 10. When the material in the fermentation chamber is discharged, the rotating door plate 14 is rotated and opened by electricity to put the material into the fermentation chamber for processing. By stirring and preheating the material, the fermentation efficiency of the material can be improved.

[0043] The working principle of this utility model is as follows: When fermentation is required, the raw materials are added to the inner wall of the fermentation tank 10 through the feed inlet 11 and the drive motor 20 is turned on. The drive motor 20 drives the main stirring blade 24 to rotate through the stirring shaft 21 and the mounting sleeve 23 on it to mix the materials and assist the materials in fermentation. When the fermentation is completed, the materials can be discharged by opening the solenoid valve on the discharge port 13 at the bottom of the fermentation tank 10.

[0044] When the material is in the mixing stage, the pressure on the main stirring blade 24 is relatively large. The material squeezes the pressure film 61 on the main stirring blade 24, causing the pressure film 61 to deform and push the first piston plate 62 to move. The first piston plate 62 moves and transports the gas at the bottom of the pressure sleeve 60 through the exhaust pipe 52, the gas collecting pipe 51 and the main conveying pipe 50 to the connecting pipe 53. The gas is then transported to the control box 70 through the diversion pipe 54 to squeeze the third piston plate 73. The movement of the third piston plate 73 drives the second piston plate 72 to move through the fixed plate 71, reducing the gas pressure in the conductive sleeve 42. The negative electrode plate 43 and the positive electrode plate 44 slide closer to each other in the conductive sleeve 42 through the rod to reduce the resistance, thereby increasing the output current at the drive motor 20, which in turn increases the speed at the main stirring blade 24 and drives the electric telescopic rod 84 to retract and increase the angle of the main stirring blade 24.

[0045] When the material is in the fermentation stage, the pressure on the main stirring blade 24 caused by the material compression decreases. By following the above steps, the output current of the drive motor 20 can be reduced, thereby reducing the speed of the main stirring blade 24, and the amount of contraction of the electric telescopic rod 84 can be reduced, thereby reducing the angle of the main stirring blade 24.

[0046] When this utility model is in use, the resistance at the negative electrode plate 43 and the positive electrode plate 44 can be dynamically adjusted according to the pressure of the material at different stages through the control components and pressure-bearing components. Then, the speed of the main stirring blade 24 can be adjusted by adjusting the output current at the drive motor 20. The speed of the main stirring blade 24 can be dynamically adjusted according to the pressure of the material at different stages, so as to avoid the main stirring blade 24 speed being too fast or too slow, which would affect the fermentation effect and cause energy waste.

[0047] Through the set control and rotation components, the angle of the main stirring blade 24 can be dynamically adjusted according to the pressure of the material at different stages. During the mixing stage, the angle of the main stirring blade 24 is increased to facilitate the exchange of materials at different liquid levels and improve the mixing effect. During the fermentation stage, the angle of the main stirring blade 24 is decreased to avoid excessive shear force that could affect the survival of yeast and thus the fermentation effect.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
