Description

Technical Field

[0001] This utility model relates to the field of fermentation equipment technology, and in particular to a kelp vinegar fermentation tank. Background Technology

[0002] Kelp vinegar is a specialty vinegar product made primarily from kelp. It combines the nutrition of marine ingredients with traditional fermentation techniques, offering both flavor and health benefits. In recent years, it has become increasingly popular among consumers. Kelp vinegar uses high-quality kelp as its core ingredient. Kelp is rich in iodine, alginic acid, mannitol, dietary fiber, various minerals, and vitamins. It is also combined with rice and sorghum grains to provide a sugar source for fermentation. Fermentation tanks are required during the processing and fermentation of kelp vinegar.

[0003] During the fermentation of kelp vinegar, the activity of acetic acid bacteria is extremely sensitive to temperature. However, most existing fermentation tanks use simple jacketed temperature control, which only has a single jacket on the outside of the tank to circulate hot or cold water. This makes it impossible to accurately control the temperature uniformity inside the tank. The current solution is to replace the single jacket with a double or multi-layer spiral jacket structure to increase the heat exchange area and equip it with a high-precision temperature sensor and intelligent temperature controller to control the temperature difference inside the tank. However, there is still the problem of unreasonable stirring intensity. In high-viscosity fermentation liquid, there will be dead zones in the stirring, resulting in uneven mixing of materials. Nutrients cannot be fully transferred to the acetic acid bacteria, affecting the fermentation efficiency and making it difficult to reach the optimal state of fermentation. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a kelp vinegar fermentation tank, including a protective frame 1, a preparation mechanism 2 is provided inside the protective frame 1, the preparation mechanism 2 is used to improve fermentation efficiency, and an injection mechanism 3 is provided on the front side of the top wall of the protective frame 1, the injection mechanism 3 is used to precisely control the amount of air injected.

[0032] The preparation mechanism 2 includes a double-shell 201. A top cover 202 is rotatably mounted on the top of the double-shell 201. A connecting shell 203 is connected to the right side of the double-shell 201, through which the fermentation broth can be circulated and injected. A filter plate 204 is fixedly mounted on the left side of the connecting shell 203, which can prevent the fermentation material from entering. A guide shell 205 is connected to the right side of the connecting shell 203. An annular nozzle 206 is connected to the bottom left end of the guide shell 205, so that the broth enters the guide shell 205 through the connecting shell 203 and is then output through the annular nozzle 206. Subsequently, the fermentation broth is agitated by the stirring component 207 and re-enters the connecting shell 203 to complete the circulation. The bottom wall of the annular nozzle 206 is fixedly mounted on the double-shell 201. The bottom wall of the double-shell 201 is equipped with a stirring component 207, which improves fermentation efficiency and avoids the existence of dead zones in the stirring. The stirring component 207 includes a servo motor 2071. The outer wall of the servo motor 2071 is fixedly connected to the bottom of the double-shell 201, so that the rotating column 2072 with multi-functional stirring blades 2073 completes the stirring under the drive of the servo motor 2071, thereby promoting the fermentation process. The output end of the servo motor 2071 is fixedly connected to the rotating column 2072. Two stirring blades 2073 are fixedly connected to the outer wall of the rotating column 2072. Multiple arc-shaped grooves 2074 are opened on one side of the stirring blades 2073. The opening of multiple arc-shaped grooves 2074 improves the dissolved oxygen distribution effect.

[0033] Specifically, the preparation mechanism 2 within the protective frame 1 constructs a fermentation environment through a double-layered shell 201 and supporting components, improving fermentation efficiency. The top cover 202, rotatably mounted on the top of the double-layered shell 201, facilitates opening and closing. The connecting shell 203 on the right serves as a circulation channel for the fermentation broth, while the filter plate 204 fixed on its left prevents fermentation material from entering, ensuring unobstructed circulation. The guide shell 205 on the right side of the connecting shell 203 connects to the annular nozzle 206 at the bottom. The fermentation broth flows through the connecting shell 203 into the guide shell 205, and then is evenly output to the interior of the double-layered shell 201 by the annular nozzle 206, achieving broth circulation. The stirring component 207 at the bottom of the double-layered shell 201... To further enhance the fermentation effect, the servo motor 2071 is fixed to the bottom of the double-layer shell 201 on its outer wall, serving as a power source to drive the rotating column 2072 connected to the output end to rotate. The rotating column 2072 drives the two stirring blades 2073 fixed on the outer wall to rotate, stirring the fermentation liquid and fermentation material inside the double-layer shell 201. Multiple arc-shaped grooves 2074 opened on one side of the stirring blades 2073 change the liquid flow path during the stirring process, promote the mixing of air and fermentation liquid, improve the uniformity of dissolved oxygen distribution, avoid stirring dead zones, and accelerate the fermentation process. After being stirred by the stirring component 207, the fermentation liquid re-enters the circulation path through the connecting shell 203. All components work together to ensure that the fermentation process is carried out efficiently and stably.

[0034] Reference Figure 1 , Figure 2 and Figure 5 The injection mechanism 3 includes a connecting plate 301, the bottom of which is fixedly connected to the front side of the top wall of the protective frame 1. An electric push rod 302 is fixedly connected to the front side of the connecting plate 301. Activation of the electric push rod 302 causes the push plate 303 to move. The front end of the electric push rod 302 is fixedly connected to the push plate 303. The middle front side of the double-layer shell 201 is connected to the injection shell 304. A connecting rod 305 is fixedly connected to the bottom rear side of the push plate 303, thereby driving the push plate 303 to move. The rod 305 completes the sliding displacement, and the rear end of the connecting rod 305 is fixedly connected to the silicone scraper column 306. The outer wall of the silicone scraper column 306 is slidably connected to the inner wall of the injection shell 304. Then, the injection shell 304 is injected with air through the opening of the solenoid valve 307. Thus, under the displacement of the silicone scraper column 306, the air inside can be accurately injected into the interior of the double shell 201, so as to achieve the purpose of dynamically adjusting the ventilation according to the fermentation stage and improve the gas utilization rate. The left side of the injection shell 304 is connected to the solenoid valve 307.

[0035] Specifically, the injection mechanism 3 is installed on the front side of the top wall of the protective frame 1 to achieve precise control of the air injection volume. The bottom of the connecting plate 301 is fixed to the front side of the top wall of the protective frame 1. The electric push rod 302 fixed on the front side serves as a power source. After starting, it drives the push plate 303 connected to the front end to make linear displacement. The injection shell 304 connected to the middle of the front side of the double shell 201 is used to temporarily store and transport air. The solenoid valve 307 connected to its left side controls the air inflow. The connecting rod 305 fixed to the bottom of the rear side of the push plate 303 moves in coordination with the silicone scraper column 306 connected to the rear end. The outer wall of the injection shell 304 slides against the inner wall. When the solenoid valve 307 is opened and air enters the injection shell 304, the electric push rod 302 drives the push plate 303 to move forward. Through the connecting rod 305, the silicone scraper 306 slides inside the injection shell 304, accurately pushing the air inside the shell into the double-layer shell 201. By adjusting the displacement and speed of the electric push rod 302, the volume of air injected each time can be controlled, so as to dynamically adjust the ventilation according to the oxygen demand at different stages of fermentation, avoid air waste, improve gas utilization, and provide a suitable oxygen environment for the fermentation process.

[0036] Reference Figure 1 , Figure 4 and Figure 5 A control switch 4 is fixedly connected to the right side of the flow guide shell 205. The control switch 4 is electrically connected to the servo motor 2071, the electric push rod 302 and the solenoid valve 307 respectively. A sealing ring 208 is fixedly connected to the inner top wall of the top cover 202. The bottom of the sealing ring 208 is engaged with the top of the double shell 201. The injection mechanism 3 also includes a sealing ring 308. The outer wall of the sealing ring 308 is fixedly connected to the front side of the inner wall of the injection shell 304.

[0037] Specifically, the control switch 4, which is electrically connected to the servo motor 2071, the electric push rod 302 and the solenoid valve 307 respectively, enables the control switch 4 to open and close the equipment. The sealing ring 208 can improve the sealing performance between the double shell 201 and the top cover 202, and the sealing ring 308 can increase the sealing effect of the injection shell 304.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The stirring assembly 207 also includes two scrapers 20755, with the adjacent sides of the two scrapers 20755 respectively rotatably connected to one side of the corresponding stirring blade 2073; a plurality of connecting seats 5 are fixedly connected to the bottom of the outer wall of the protective frame 1, and a support column 6 is fixedly connected inside the connecting seat 5.

[0039] Specifically, the scraper 2075 can reduce the amount of material adhering to the inner wall of the double shell 201, and the connection between the connecting seat 5 and the support column 6 can improve the stability of the fermenter.

[0040] Working principle: The double-shell 201 serves as the main fermentation container. The top cover 202, which is rotatably mounted on the top, facilitates opening and closing. The right side of the double-shell 201 is connected to the connecting shell 203. The filter plate 204 fixed on the left side of the connecting shell 201 prevents fermented material from entering the circulation channel. The right side is connected to the guide shell 205. The annular nozzle 206 at the bottom left end of the guide shell 205 is fixed to the inner bottom wall of the double-shell 201. In the stirring assembly 207, the servo motor 2071, fixed to the bottom of the double-shell 201, drives the rotating column 2072 at the output end to rotate. The rotating column 2072 drives the outer wall... The fixed stirring blade 2073 rotates, and the arc-shaped groove 2074 on the stirring blade 2073 optimizes dissolved oxygen distribution during rotation. During the operation of the stirring assembly 207, the fermentation broth flows through the connecting shell 203 into the guide shell 205, and is then sprayed out by the annular nozzle 206. Under the agitation of the stirring blade 2073, it re-enters the connecting shell 203, forming a circulating flow field. This circulation mechanism eliminates dead zones in the stirring process, ensuring that nutrients and dissolved oxygen are evenly distributed within the double-layered shell 201. Combined with the filter plate 204, this prevents blockage of the circulation channels, ensuring a smooth and efficient fermentation process. This improves fermentation efficiency and avoids the poor results of mixed fermentation.

[0041] Furthermore, the injection mechanism 3 enables precise control of the aeration rate. The bottom of the connecting plate 301 is fixed to the front side of the top wall of the protective frame 1. The outer wall of the silicone scraper 306 slides against the inner wall of the injection shell 304, which is connected to the middle of the front side of the double-layer shell 201. When the solenoid valve 307 is opened, air enters the shell through the left side of the injection shell 304. At this time, the electric push rod 302 is activated, which drives the push plate 303 to move, causing the connecting rod 305 and the silicone scraper 306 to slide inside the injection shell 304, pushing the air inside the shell into the double-layer shell 201. By controlling the extension and retraction length and speed of the electric push rod 302, the amount of air pushed by the silicone scraper 306 can be adjusted. The aeration rate can be dynamically adjusted according to the actual needs of different fermentation stages, avoiding the problem of inflexible control of the aeration rate, achieving precise gas supply, effectively improving gas utilization, and providing a suitable oxygen environment for the fermentation process.

[0042] 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.
