Description

Technical Field

[0001] This utility model belongs to the technical field of fermentation tanks for pickling and marinating, and specifically relates to a fermentation tank for pickling and marinating with a stirring structure. Background Technology

[0002] A fermentation tank with a turning mechanism is an advanced device designed to address many problems associated with traditional fermentation methods for pickled vegetables. It mainly consists of the fermentation tank body, a reinforced top frame, a turning mechanism, and a pulsating fermentation device. The fermentation tank body provides the fermentation space, and the reinforced top frame enhances structural stability. The turning motor in the turning mechanism drives the turning output shaft to rotate via a reducer, causing the stirring rollers and turning blades to stir and turn the pickled vegetables and fermentation liquid, effectively solving the problem of uneven fermentation in traditional methods and improving product quality and taste.

[0003] However, traditional fermentation methods for pickled vegetables have significant shortcomings. Most traditional fermentation tanks lack specialized agitation devices, making it difficult for the pickled vegetables to obtain sufficient oxygen during fermentation. Insufficient oxygen greatly reduces fermentation efficiency, prolongs fermentation time, and increases production costs and cycles. Furthermore, incomplete fermentation frequently occurs, directly affecting product quality and resulting in poor taste and flavor. In addition, traditional fermentation tanks are often structurally simple, failing to consider how to better meet the oxygen requirements during fermentation or to effectively address issues such as uneven fermentation, making them unsuitable for the high-quality pickled vegetable production requirements of the modern food processing industry. Utility Model Content

[0004] The purpose of this invention is to provide a fermentation tank for pickling with a stirring structure, in order to solve the problem that most traditional fermentation tanks mentioned in the background art lack a dedicated agitation fermentation device. This makes it difficult for pickled vegetables to obtain sufficient oxygen during the fermentation process. Due to insufficient oxygen, the fermentation efficiency is greatly reduced, the fermentation time is prolonged, and the production cost and production cycle are increased.

Both gas collecting pipes are placed close to the inner wall of the bottom end of the fermentation tank body. Multiple bubble nozzles are equidistantly arranged at the top ends of both gas collecting pipes.

[0007] Preferably, the fermentation tank body has perforations inside near the lower left and lower right front ends, and sealing sleeves are installed in the perforations. The two sealing sleeves are respectively fitted onto the outside of the front ends of the two gas collecting pipes, and the connection between the gas collecting pipes and the sealing sleeves is further reinforced with sealant.

[0008] Preferably, the agitated fermentation device further includes an air-blowing pipe A, an air inlet, a pump box, an air outlet, and an air-blowing pipe B.

An air-blowing pipe B is connected between the valve body inlet of check valve B and the air inlet at the right end of the pump box.

[0009] Preferably, blowers are provided on both the left and right sides of the center inside the pump box. The air outlets of the two blowers are connected to the air outlets at the left and right ends of the pump box, respectively. The air inlets of the two blowers are connected to the two air inlets at the top of the pump box, respectively. The blowers are electrically connected to an external control power supply via wires.

[0010] Preferably, a drain outlet is provided on the lower side of the center of the right end of the fermentation tank body. The drain outlet is close to the bottom of the fermentation tank body and is connected to the inside of the fermentation tank body. An external flange is provided on the outside of the right end of the drain outlet.

[0015] This invention adds a connected agitator to the front and bottom of a fermentation tank with a stirring structure. The agitator, with a gas collecting pipe and bubble nozzle at the bottom of the tank, blows gas and generates numerous bubbles. These bubbles, as they rise, cause the fermentation liquid and pickled vegetables to tumble, resulting in a more uniform fermentation process. Working in conjunction with the stirring mechanism, where the stirring rollers and blades further enhance the uniformity of fermentation and prevent over- or under-fermentation that can occur in traditional fermentation tanks, the quality of the pickled vegetables is improved. A blower pump pumps air into the gas collecting pipe through the blowing pipe, providing ample oxygen for the fermentation process. During fermentation, microorganisms require oxygen for respiration; a sufficient oxygen supply promotes their growth and metabolism, accelerating the fermentation process. Simultaneously, the oxygen in the bubbles dissolves better in the fermentation liquid, improving oxygen utilization. Attached Figure Description

[0020] 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.

[0021] This utility model provides, for example Figure 1-3 The fermentation tank with a stirring structure shown includes a fermentation tank body 1 and a reinforcing top frame 2 set at the top of the fermentation tank body 1. Screw fixing plates 6 are set at the center of the top of the front and rear ends and the left and right ends of the reinforcing top frame 2. Vertical supports 5 are welded to the top of each of the four screw fixing plates 6. A frame plate 8 is set on the upper side of the center of the reinforcing top frame 2. Horizontal supports 7 are welded to the left and right ends and the front and rear ends of the frame plate 8. The four horizontal supports 7 are fixedly connected to the four vertical supports 5 respectively. A stirring mechanism 9 is set on the frame plate 8. The stirring mechanism 9 includes a stirring motor 10, a reducer 11, a stirring output shaft 12, stirring blades 13, and a stirring roller 14. The reducer 11 is fixed to the top of the frame plate 8 by flanges and screws. The stirring motor 10 is set at the top of the reducer 11. The stirring motor 10 and the reducer 11 are connected by a transmission. The bottom end of the output shaft of the reducer 11 is connected by a coupling. The shaft is connected to a turning output shaft 12, which is vertically inserted into the center of the fermentation tank body 1. Multiple sets of turning blades 13 and stirring rollers 14 are arranged on the lower side of the center of the turning output shaft 12. The multiple sets of turning blades 13 and stirring rollers 14 are arranged alternately. When the turning output shaft 12 rotates, it can be stirred by the stirring rollers 14. When the turning output shaft 12 rotates, it can be turned up and down by the turning blades 13. The turning motor 10 in the turning mechanism 9 provides power. After being reduced by the reducer 11, it drives the turning output shaft 12 to rotate. The function of the stirring rollers 14 is to stir the fermentation liquid and pickled vegetables in the horizontal direction, so that they are fully mixed and promote the uniform distribution of fermentation substances. The turning blades 13 turn up and down in the vertical direction to prevent the pickled vegetables from piling up at the bottom and ensure that all parts can be in full contact with the fermentation liquid, thereby improving the uniformity and efficiency of fermentation.

[0022] like Figure 1 and Figure 2As shown, a drain outlet 4 is located on the lower side of the center of the right end of the fermentation tank body 1. The drain outlet 4 is close to the bottom of the fermentation tank body 1 and is connected to the interior of the fermentation tank body 1. An external flange is provided on the outside of the right end of the drain outlet 4. The drain outlet 4 is fixedly connected to the external sewage pipe through the external flange on the right end and multiple screws. The stirring motor 10 in the stirring mechanism 9 provides power. After being reduced by the reducer 11, it drives the stirring output shaft 12 to rotate. The function of the stirring roller 14 is to stir the fermentation liquid and pickled vegetables in the horizontal direction, so that they are fully mixed and promote fermentation. To ensure uniform distribution of the fermentation liquid, the stirring blades 13 vertically stir the fermented vegetables, preventing them from piling up at the bottom and ensuring that all parts are in full contact with the fermentation liquid, thereby improving the uniformity and efficiency of fermentation. When using this fermentation tank with a stirring structure, first check whether the fermentation tank body 1, the reinforced top frame 2, the stirring mechanism 9, and the drain outlet 4 are intact, and ensure that the stirring motor 10, the reducer 11, and other equipment are operating normally and that the connections are firm and reliable. Then, put the fermented vegetables and fermentation liquid into the fermentation tank body 1, and pay attention to controlling the fermentation process. The ratio of pickled vegetables to fermentation liquid is adjusted to ensure fermentation effectiveness. When stirring is required, the stirring motor 10 is activated. The stirring motor 10 drives the stirring output shaft 12 to rotate via the reducer 11. The stirring roller 14 begins to stir the fermentation liquid and pickled vegetables, ensuring they are evenly mixed. The stirring blades 13 tumble the mixture from top to bottom, ensuring the pickled vegetables are fully fermented at different depths. The speed and running time of the stirring motor 10 are adjusted according to the actual situation. The intensity and frequency of stirring can be appropriately adjusted by observing the fermentation status of the pickled vegetables to achieve the best fermentation effect. During the process, regularly observe parameters such as temperature and humidity in the fermentation tank, as well as the fermentation status of the pickled vegetables. If necessary, make appropriate adjustments and interventions. After fermentation is complete, open the drain outlet 4 and connect it to the external sewage pipe through the external flange and screws to discharge the waste liquid after fermentation, keeping the fermentation tank clean and hygienic. After fermentation is complete, the fermentation tank needs to be cleaned and disinfected to remove residual pickled vegetables and fermentation liquid. At the same time, check and maintain components such as the stirring mechanism 9 and the drain outlet 4 to ensure that the equipment operates normally the next time it is used.

[0023] like Figure 1 and Figure 3As shown, a pulsating fermentation device 3 is connected to the front end and bottom end of the fermentation tank body 1. The pulsating fermentation device 3 includes a check valve A15, a check valve B20, a gas collecting pipe 22, and a bubble nozzle 23. Check valves A15 and B20 are respectively installed near the lower left and lower right front ends of the fermentation tank body 1. The installation of check valves A15 and B20 can prevent the fermentation liquid from flowing back into the blower pump and the gas collecting pipe 22, ensuring the normal operation of the device. Both check valves A15 and B20 have valve body outlets at their rear ends. Gas collecting pipes 22 are connected to the valve body outlets of both check valves A15 and B20. Both gas collecting pipes 22 are placed close to the inner wall of the bottom end of the fermentation tank body 1. The placement of the gas collection pipes ensures that the bubbles are evenly distributed at the bottom of the fermentation tank, promoting thorough mixing of the fermentation liquid and pickled vegetables and improving fermentation uniformity. Multiple bubble nozzles 23 are equidistantly positioned at the top of each of the two gas collection pipes 22. These nozzles generate a large number of fine bubbles, increasing the contact area between the bubbles and the fermentation liquid and pickled vegetables, improving oxygen solubility, and accelerating the fermentation process. The fermentation tank body 1 has perforations near the lower left and lower right front ends, with sealing sleeves installed within these perforations. These two sealing sleeves are respectively fitted onto the outer ends of the two gas collection pipes 22, and the connection between the gas collection pipes 22 and the sealing sleeves is further reinforced with sealant. The use of sealing sleeves and sealant ensures the airtightness of the connection between the gas collection pipes 22 and the fermentation tank body 1, preventing gas leakage.

[0024] like Figure 1 and Figure 3As shown, the agitated fermentation device 3 also includes an air blasting pipe A16, an air inlet 17, a pump box 18, an air outlet 19, and an air blasting pipe B21. A pump box 18 is located at the center of the outer wall at the front end of the fermentation tank body 1. Air inlets 17 are located on both the left and right sides of the center of the top of the pump box 18, and air outlets 19 are located at both ends of the pump box 18. Check valves A15 and B20 both have valve body inlets at their tops. The valve body inlet of check valve A15 is connected to the air inlet 17 at the left end of the pump box 18. A blower pipe B21 connects the valve body inlet of the check valve B20 to the air inlet 17 at the right end of the pump box 18. Blower pumps are installed on both sides of the center of the pump box 18. The air outlets of the two blower pumps are connected to the air outlets 19 at the left and right ends of the pump box 18, respectively. The air inlets of the two blower pumps are connected to the two air inlets 17 at the top of the pump box 18, respectively. The blower pumps are electrically connected to an external control power supply via wires. The fermentation device 3 is activated by the blower pumps. Air is drawn in through inlet 17, pressurized by the pump, and discharged through outlet 19. Air then enters check valves A15 and B20 via blast pipes A16 and B21, respectively, and then enters collection pipe 22. Collection pipe 22 is placed against the inner wall of the bottom of fermentation tank 1. Gas is blown into the bottom of fermentation tank 1 through bubble nozzle 23 at the top, generating numerous bubbles. As these bubbles rise, they cause the fermentation liquid and pickled vegetables to tumble, promoting uniform distribution of fermentation substances and increasing oxygen supply, thus accelerating the fermentation process. The combined use of the agitator fermentation device 3 and the stirring mechanism 9 makes the fermentation process more efficient. The stirring mechanism 9 continuously stirs and turns the pickled vegetables, while the bubbles generated by the agitator fermentation device 3 further promote the flow and mixing of the fermentation liquid. This dynamic fermentation environment facilitates full contact between microorganisms and pickled vegetables, accelerating the fermentation reaction. Compared to traditional static fermentation methods, this significantly shortens fermentation time and improves production efficiency.
