Description
Technical Field
[0001] This utility model relates to the technical field of fermentation temperature control devices, and in particular to a vinegar fermentation temperature control device. Background Technology
[0002] The main raw materials for edible vinegar fermentation are grains with high starch content, such as rice, wheat, and corn. First, these raw materials are processed to turn them into saccharified starch. Then, yeast and water are added for fermentation. During fermentation, the yeast converts the saccharified starch into ethanol and carbon dioxide. Acetic acid fermentation is the process of converting ethanol in the alcoholic fermentation liquid into acetic acid. The temperature for acetic acid fermentation is generally between 30 and 35°C, and the fermentation time is usually between 5 and 7 days. The flavor of acetic acid is affected by the fermentation temperature. Large temperature fluctuations can easily affect the taste of acetic acid. Nowadays, fermentation tanks are generally used as temperature control devices for vinegar fermentation.
[0003] For example, Chinese utility model patent application number 202323549151.6 discloses a vinegar fermentation temperature control device, including: a fermentation tank and an electric heater; the fermentation tank has a stainless steel inner liner, a heat insulation layer and an outer shell in sequence from the inside to the outside, and multiple heat-conducting pipes are arranged around the circumference of the fermentation tank. The electric heater has multiple heating rods, which are inserted and fixed from the ends of the heat-conducting pipes. This utility model sets heat-conducting pipes in the tank body, and the heating rods can be inserted into the heat-conducting pipes to heat the local fermentation liquid more quickly. The heated fermentation liquid is quickly spread by stirring with a stirring blade, so that the fermentation liquid heats up evenly. Three temperature sensors detect the temperature changes in the upper, middle and lower areas. Heating stops when the temperature of all three areas reaches the fermentation temperature. If one area is lower than the fermentation temperature, the electric heater and stirring blade are turned on, thereby reducing temperature fluctuations and improving the fermentation quality of acetic acid. Fiberglass is set in the jacket of the fermentation tank. The low thermal conductivity of fiberglass can play a role in heat preservation, reducing heat loss and saving energy.
[0004] However, in the aforementioned vinegar fermentation temperature control device, the temperature varies in different areas of the liquid inside the tank during use, and even with stirring, microbial cells or metabolic products still accumulate on the inner wall of the tank, affecting the reaction rate. Therefore, those skilled in the art have provided a vinegar fermentation temperature control device to solve the problems mentioned in the background art. Utility Model Content

[0036] The auxiliary fermentation mechanism 5 includes a fixed shell 51. A mounting pad 52 is fixed to the inner wall of one side of the fixed shell 51. A servo motor 53 is fixed to one side of the mounting pad 52. A rotating frame 54 is fixed to the outer side of the output shaft of the servo motor 53. One end of the rotating frame 54 is rotatably connected to a transmission connecting frame 55 via a rotating shaft. One end of the transmission connecting frame 55 is rotatably connected to a movable metal rod 58 via a rotating shaft. A reinforcing plate 56 is fixed to the inner bottom wall of the fixed shell 51. A guide sleeve 57 is fixed to the outer side of the reinforcing plate 56. A movable metal block 59 is fixed to the outer side of the movable metal rod 58. A metal sliding sleeve 510 is fixed to the bottom of the movable metal block 59. The shell 51 and the support frame 4 are fixedly connected to ensure a stable connection between the support frame 4 and the fixed shell 51. A diagonal brace 512 is fixed to the inner wall of one side of the fixed shell 51, and a metal rail 511 is fixed to the top of the diagonal brace 512 to ensure the stability of the support structure of the diagonal brace 512 on the metal rail 511. The metal sliding sleeve 510 and the metal rail 511 are sliding fit components. The guide sleeve 57 has a through hole inside to accommodate the movement of the movable metal rod 58. The guide sleeve 57 limits the movement of the movable metal rod 58. A limiting hole is opened inside the fixed shell 51, and the size of the limiting hole is adapted to the size of the movable metal rod 58.
[0037] The temperature control and maintenance mechanism 6 includes a fixed bracket 61, a protective sleeve 62 fixed to the top of the fixed bracket 61, a movable sleeve 63 rotatably connected to the outer side of the protective sleeve 62 via a rotating shaft, a reinforcing sleeve 64 fixed to the inner bottom of the movable sleeve 63, a fixing pad 65 fixed to the outer side of the protective sleeve 62, a fixing threaded post 66 fixed to one side of the fixing pad 65, a limit sleeve 69 fixed to the outer side of the movable sleeve 63, a shim 67 movablely adjusted to the outer side of the fixing threaded post 66, a positioning threaded sleeve 68 threadedly connected to the outer side of the fixing threaded post 66, the fixed bracket 61 and the fermentation tank 1 fixedly connected, one side of the reinforcing sleeve 64 fitting against the heating tube 3, and a through hole for accommodating the heating tube 3 to pass through the interior of the fixed bracket 61.
[0038] Working principle: The vinegar solution undergoes fermentation and temperature control within the fermentation tank 1. Temperature control is achieved through heating elements 3. During fermentation, the stirring motor at the top of the fermentation tank 1 is periodically activated, driving the stirring frame to agitate the vinegar solution. Simultaneously, the servo motor 53 within the fixed shell 51 is activated. The output shaft of the servo motor 53 rotates, driving the rotating frame 54 to rotate. This causes the transmission connecting frame 55 to move the moving metal rod 58 horizontally back and forth. The moving metal block 59 drives the metal sliding sleeve 510 to move back and forth outside the metal track 511, serving a guiding function. After the moving metal rod 58 moves back and forth, one end of it intermittently impacts the outer wall of the fermentation tank 1. The mechanical vibration generated by this impact damages the microbial cells or metabolic cells on the inner wall of the fermentation tank 1. The device can reduce the deposition of metabolic products and decrease local concentration differences, allowing for more thorough contact between microorganisms and thus increasing the reaction rate. It is equipped with a temperature control and maintenance mechanism 6. The fermenter 1 is heated and its temperature is controlled by the heating pipe 3. After the heating pipe 3 is installed and fixed to the fermenter 1, it passes through the fixed support 61. Then, the movable sleeve 63 on the outside of the protective sleeve 62 is rotated, allowing the limiting sleeve 69 to be movably fitted onto the outside of the fixed threaded post 66. A gasket 67 can then be movably fitted onto the outside of the fixed threaded post 66, and a positioning threaded sleeve 68 is threadedly connected to the fixed threaded post 66. This facilitates a stable connection between the movable sleeve 63 and the protective sleeve 62, and ensures that the corresponding surface of the reinforcing sleeve 64 is tightly pressed against the outside of the heating pipe 3, strengthening the external support and protection of the heating pipe 3 and ensuring stable heating and temperature control effects.
