Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermented bean curd technology, and in particular to a low-cost fermented bean curd fermentation reaction device. Background Technology
[0002] In food factories, when producing fermented bean curd, a low-cost flavored fermented bean curd fermentation reactor is needed to effectively control the temperature and humidity during fermentation, providing a relatively stable environment for the fermented bean curd and making the fermentation process more uniform and stable.
[0003] When using this device, the marinated tofu blocks are first laid flat on the tray of the device, and then mold seeds, such as Aspergillus or Aspergillus, are evenly sprinkled on the surface of the tofu to allow it to ferment. The tray is then placed on the shelf inside the device, which provides a relatively stable environment for the tofu to ferment. During the fermentation process, in order to make the fermentation process more even, the tofu at the bottom needs to be moved to the top to prevent over-fermentation or uneven fermentation.
[0004] Considering that the tofu inside the device is usually turned over manually by alternating the top and bottom of the container, this process is not only labor-intensive, especially during large-scale production where a large number of workers are needed to ensure production, but also inefficient, leading to increased turning time and the potential for external contaminants such as dust and bacteria to pollute the fermentation environment and affect the quality of the fermented tofu. Therefore, a low-cost flavored fermented tofu fermentation reactor is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a low-cost flavored fermented bean curd fermentation reaction device, which aims to improve the existing technology where the tofu is manually replaced from top to bottom during the turning operation. This not only increases labor intensity, but is also inefficient, especially in large-scale production. Furthermore, the extended operation time may allow external contaminants, such as dust and bacteria, to enter the fermentation environment, thereby affecting the quality of the fermented bean curd.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a low-cost flavored fermented bean curd fermentation reaction device, comprising a shell, a motor fixedly connected to the rear end of the outer surface of the shell, a rotating frame fixedly connected to the output shaft of the motor, the outer surface of the rotating frame rotatably connected to the inner surface of the shell, a rotating shaft rotatably connected to the inner surface of the rotating frame, a tray fixedly connected to the bottom end of the outer surface of the rotating shaft, and a temperature and humidity control component provided on the inner surface of the shell.
[0007] As a further description of the above technical solution:
[0008] The temperature and humidity control component includes a heating lamp, a humidifier, and a control panel. The outer surface of the heating lamp is fixedly connected to the top of the inner surface of the housing, the outer surface of the humidifier is fixedly connected to the bottom of the inner surface of the housing, and the outer surface of the control panel is fixedly connected to the right side of the outer surface of the housing.
[0009] As a further description of the above technical solution:
[0010] A threaded rod is rotatably connected to the left side of the inner surface of the rotating frame. A connector is threaded through and threaded to the outer surface of the threaded rod. The bottom end of the connector is inserted into the left side of the inner surface of the rotating shaft. The outer surface of the connector is slidably connected to the left side of the inner surface of the rotating frame. Multiple sets of connectors are provided.
[0011] As a further description of the above technical solution:
[0012] A second bevel gear is fixedly connected to the middle of the outer surface of the threaded rod. A first bevel gear meshes with the bottom of the outer surface of the second bevel gear. An operating rudder is fixedly connected to the left side of the outer surface of the first bevel gear. The outer surfaces of the first bevel gear and the second bevel gear are rotatably connected to the left side of the inner surface of the rotating frame.
[0013] As a further description of the above technical solution:
[0014] A sealing door is hinged to the front end of the outer surface of the housing, and the right side of the outer surface of the sealing door is fixedly connected to the right side of the front end of the housing by a pin.
[0015] As a further description of the above technical solution:
[0016] An operating door is slidably connected to the middle of the inner surface of the sealed door, and there are two sets of operating doors.
[0017] As a further description of the above technical solution:
[0018] A counterweight is fixedly connected to the bottom of the outer surface of the tray.
[0019] As a further description of the above technical solution:
[0020] A triangular connecting rod is fixedly connected to the bottom of the outer surface of the rotating shaft and the top of the tray.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, by providing a rotating frame and trays, when it is necessary to turn the tofu over, the rotating frame is driven to rotate by starting the motor, so that multiple sets of trays at the bottom of the rotating frame are simultaneously replaced with the trays at the top, so as to achieve a quick turning operation, avoid a large amount of manual operation, reduce the intensity of manual labor, reduce the waste of human resources, and thus achieve the effect of reducing labor costs.
[0023] 2. In this utility model, a triangular structure is formed between the tray and the rotating shaft through a triangular bracket. When the rotating frame drives the tray to flip and move, the tray will always remain in a downward state due to gravity because of the balance of the triangle, so that the tray can always be kept horizontal and prevent the tofu from scattering when the tray is flipped.
[0024] 3. In this utility model, by providing a threaded rod and plug-in parts, when the rotating frame is in a vertical state, rotating the operating rudder will drive the threaded rod to rotate, and the threaded rod will simultaneously drive multiple sets of plug-in parts to plug into the rotating shaft on the tray, thereby fixing multiple sets of trays at the same time. This prevents the trays from shifting or misaligning due to external forces such as vibration or tilting, thus preventing the tofu from scattering or being damaged during fermentation.

[0034] 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.
[0035] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a low-cost flavored fermented bean curd fermentation reactor, comprising a shell 1. A motor 9 is fixedly connected to the rear end of the outer surface of the shell 1, providing a fixed support for the motor 9. The output shaft of the motor 9 is fixedly connected to a rotating frame 7, enabling the motor 9 to drive the rotating frame 7 to rotate together, thus avoiding the need for extensive manual operation. The outer surface of the rotating frame 7 is rotatably connected to the inner surface of the shell 1, allowing the rotating frame 7 to rotate along the inner surface of the shell 1. A rotating shaft 12 is rotatably connected to the inner surface of the rotating frame 7, allowing the rotating shaft 12 to rotate along the inner surface of the rotating frame 7. A tray 8 is fixedly connected to the bottom end of the outer surface of the rotating shaft 12, enabling the rotating shaft 12 to rotate while rotating. The inner surface of the outer shell 1 is equipped with a temperature and humidity control component to control the temperature and humidity inside the outer shell 1, providing a relatively stable environment for the fermented bean curd and making the fermentation process more uniform and stable. The temperature and humidity control component includes a heating lamp 6, a humidifier 16, and a control panel 5. The outer surface of the heating lamp 6 is fixedly connected to the top of the inner surface of the outer shell 1, so that the heating lamp 6 can increase the temperature inside the outer shell 1. The outer surface of the humidifier 16 is fixedly connected to the bottom of the inner surface of the outer shell 1, so that the humidifier 16 can increase the humidity inside the outer shell 1. The outer surface of the control panel 5 is fixedly connected to the right side of the outer surface of the outer shell 1, so that the control panel 5 can control the motor 9, the heating lamp 6, and the humidifier 16.
[0036] Reference Figure 4 - Figure 6A threaded rod 10 is rotatably connected to the left side of the inner surface of the rotating frame 7, allowing the threaded rod 10 to rotate along the left side of the inner surface of the rotating frame 7. A connector 11 is threaded through and threaded onto the outer surface of the threaded rod 10, allowing the threaded rod 10 to rotate and drive the connector 11 to move vertically. The bottom end of the connector 11 is inserted into the left side of the inner surface of the rotating shaft 12, fixing the rotating shaft 12 at a specified angle to prevent rotation. The outer surface of the connector 11 is slidably connected to the left side of the inner surface of the rotating frame 7, allowing the connector 11 to move vertically along the left side of the inner surface of the rotating frame 7. Multiple sets of connectors 11 are provided, allowing multiple sets of connectors 11 to simultaneously fix multiple sets of rotating shafts. The effect of shaft 12 is that a second bevel gear 15 is fixedly connected to the middle of the outer surface of the threaded rod 10, so that when the second bevel gear 15 rotates, it can drive the threaded rod 10 to rotate together. The bottom end of the outer surface of the second bevel gear 15 meshes with a first bevel gear 14, so that when the first bevel gear 14 rotates, it can drive the second bevel gear 15 to rotate together due to meshing with the second bevel gear 15. An operating rudder 13 is fixedly connected to the left side of the outer surface of the first bevel gear 14, so that when the operating rudder 13 is rotated, it can drive the first bevel gear 14 to rotate together. The outer surfaces of the first bevel gear 14 and the second bevel gear 15 are both rotatably connected to the left side of the inner surface of the rotating frame 7, so that the first bevel gear 14 and the second bevel gear 15 can both rotate along the left side of the inner surface of the rotating frame 7.
[0037] Reference Figure 1 , Figure 4 , Figure 7A sealing door 2 is hinged to the front end of the outer surface of the outer shell 1, so that when the sealing door 2 is closed, a sealed space is formed inside the outer shell 1 to prevent external contaminants from contaminating the fermenting tofu. The right side of the outer surface of the sealing door 2 is fixedly connected to the right side of the front end of the outer shell 1 by a pin 4, so that the sealing door 2 can be fixed to the sealing door 2 by the pin 4 when closed, preventing the sealing door 2 from opening during fermentation. An operating door 3 is slidably connected to the middle of the inner surface of the sealing door 2, so that the operating door 3 can move laterally along the middle of the inner surface of the sealing door 2, and can operate the operating rudder 13 when the operating door 3 is opened. There are two sets of operating doors 3, so that when the rotating frame 7 rotates and drives the operating rudder 13 to another position, one set of operating doors 3 can be opened to operate the operating rudder 13. The operation is effective because a triangular connecting rod is fixedly connected to the bottom of the outer surface of the rotating shaft 12 and the top of the tray 8, so that the rotating shaft 12 and the tray 8 can form a triangle due to the triangular connecting rod. Since the vertex of the triangle is used as the rotation point, and the triangle also has the property of balance, the tray 8 can always maintain a downward state due to gravity, so that the tray 8 can always maintain a horizontal state. A counterweight 17 is fixedly connected to the bottom of the outer surface of the tray 8, and there are two sets of counterweight 17. The two sets of counterweight 17 are fixed to the bottom sides of the tray 8. Through the design of the two sets of counterweight 17, the weight on both sides of the tray 8 is increased and the weight on both sides is made the same, so that the tray 8 can maintain a horizontal state when rotating and moving. At the same time, the weight of the counterweight 17 is much higher than the weight of the tray 8 and the tofu on the tray 8, so that the tofu placed on the tray 8 will not affect the horizontal effect of the tray 8.
[0038] Working principle: When using the device, first place the pickled tofu blocks on the tray 8, then manually spray mold seeds on the surface of the tofu, then close the sealing door 2 to keep the inside of the outer shell 1 in a sealed state to prevent external contaminants from contaminating the tofu, and then control the heating lamp 6 and humidifier 16 through the control panel 5 to adjust the temperature and humidity inside the outer shell 1 to a suitable level for tofu fermentation.
[0039] When a cage-twisting operation is required, first open the top operating door 3 to allow the operating rudder 13 to rotate outside the outer shell 1. When the operating rudder 13 is rotated clockwise, the threaded rod 10 will rotate counterclockwise under the drive of two sets of bevel gears. This allows the threaded rod 10 to simultaneously disengage multiple sets of connectors 11 from the left side of the inner surface of the rotating shaft 12. The rotating shaft 12 then rotates along the inner surface of the rotating frame 7 under the influence of the weight of the tray 8. Then, start the motor 9 to drive the rotating frame 7 to rotate counterclockwise, causing the tray 8 at the bottom of the outer shell 1 to rotate to the top of the inner surface of the outer shell 1. When moved by the rotating frame 7, the tray 8 will always remain horizontal due to gravity to prevent the tofu from slipping off the tray 8. When the bottom tray 8 rotates to the top, the motor 9 is stopped, and then the bottom operating door 3 is opened. The operating rudder 13 is rotated counterclockwise to drive the threaded rod 10 to rotate clockwise. The threaded rod 10 drives multiple sets of plug-in parts 11 to plug into the inner surface of the rotating shaft 12 to fix the rotating shaft 12. This prevents the tray from shifting or becoming misaligned due to external forces such as vibration or tilting, thus preventing the tofu from scattering or being damaged during fermentation.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
