Description

Technical Field

[0001] This utility model relates to the field of vinegar fermentation tanks, and in particular to an automatic deep liquid vinegar fermentation tank. Background Technology

[0002] The automated deep liquid vinegar fermentation tank is a specialized piece of equipment for the industrial production of vinegar. It uses liquid alcohol (such as rice wine, fruit wine, or saccharified liquid) as a substrate and utilizes the metabolic activity of acetic acid bacteria in a deep liquid environment to convert alcohol into acetic acid. Simultaneously, by integrating components for stirring, aeration, and temperature control, it achieves unmanned operation of the fermentation process. It features high efficiency, large output, and strong product stability, and is widely used in large-scale vinegar production.

[0003] Currently, the basic structure of automated deep-layer liquid vinegar fermentation tanks used in industry typically includes a sealed tank, a top-mounted mechanical stirring system, and temperature sensing elements installed on the side walls. The stirring system usually uses a single rotating impeller, driven by a motor, to ensure uniform mixing of the fermentation broth and increase dissolved oxygen efficiency. Temperature control is achieved through refrigerant circulation within the tank jacket or built-in cooling coils.

[0004] There are unresolved technical bottlenecks: the single rotary stirring mode easily creates mixing dead zones within the tank, leading to uneven distribution of bacteria, oxygen, and nutrients, affecting fermentation efficiency and product quality uniformity; the equipment structure is complex, making cleaning and maintenance difficult, especially the fixed connection between the top cover and the stirring components, resulting in time-consuming and labor-intensive repairs and internal cleaning; furthermore, the lack of varying light exposure during the fermentation stage leads to low yields. Therefore, it is necessary to develop an automated deep-layer liquid vinegar fermentation tank to address the pain points of existing technologies. Utility Model Content

A transmission component is provided at one end of the first fixing plate 11. Quick-release components are provided on both sides of the outer ring of the sealing cover 2.

[0034] The transmission assembly includes a worm gear 13, one end of which is rotatably connected to the first fixed plate 11. A worm 14 is fixedly connected to the bottom of the first gear 6, one end of which is rotatably connected to both the support frame 3 and the second fixed plate 12.

A spring 24 is fixedly connected to one end of the inner wall of the limiting block 21. 4. A sliding plate 23 is fixedly connected to one end of each of the four types of sealing caps 2 and 20. A spring 24 provides continuous elastic force to keep the limiting post 25 locked in the limiting hole 26. Even if the tank 1 vibrates slightly due to stirring, the sealing cap 2 can be stably locked. The outer wall of the sliding plate 23 is slidably connected to the limiting block 21. A limiting post 25 is fixedly connected to one side of each of the four types of sliding plates 23. One end of the sliding plate 23 is slidably connected to the limiting block 21. A limiting hole 26 is opened on one side of each of the four types of limiting frames 20. By pressing the limiting post 25 inward to completely disengage it from the limiting hole 26, the limiting of the sealing cap 2 can be released. The bottom of the sealing cap 2 is fixedly connected to a sliding plate 23. A ring light 28 is fixedly connected to the top of its outer ring, and a ring diffuser 29 is fixedly connected to the top of the ring light 28. The ring diffuser 29 can make the light more uniform. A control console 27 is fixedly connected to one end of the outer ring of the tank 1. The ring light is electrically connected to the control console 27. By providing "energy light" such as green light during the growth period, the cell reproduction is accelerated. During the acid production period, "regulatory light" such as blue light is provided to maximize the acetic acid synthesis rate, which can shorten the entire fermentation cycle. An oxygen supply pipe 22 is fixedly connected to one end of the top of the sealing cap 2 and the other end of the pipe. One end of the oxygen supply pipe 22 can be connected to an external oxygen supply component to supply oxygen to the inside of the tank 1.

[0035] Working principle: The operator injects liquid alcohol raw material and acetic acid bacteria into the tank 1 through the feed inlet on one side of the top of the sealing cover 2. After feeding, the feed inlet is sealed, the bottom of the sealing cover 2 is aligned with the top of the tank 1 and pressed inward to squeeze the limiting post 25. After reaching the appropriate position, the limiting post 25 is released, and the limiting post 25 is locked into the limiting hole 26 by the elastic force of the spring 24. When disassembling, the limiting posts 25 on both sides are squeezed inward to compress the spring 24 and make the limiting post 25 disengage from the limiting hole 26. The handle on the top of the sealing cover 2 is then lifted to remove the sealing cover 2 together with the stirring assembly. After the servo motor 5 starts, its output drives the first gear 6 to rotate. The first gear 6 meshes with the second gear 7, driving the spline sleeve 8 to rotate. Through the spline sleeve 8, the spline rod 10 rotates synchronously, thereby causing the bottom stirring rack 19 to rotate, achieving radial mixing of the raw materials. At the same time, the first gear 6 drives the bottom worm 14 to rotate. The worm 14 meshes with the worm wheel 13, causing the worm wheel 13 to rotate. The first rotating block 15 at the other end of the worm wheel 13 pulls the second rotating block 16 through the connecting rod 17, driving the third gear 18 to reciprocate. The third gear 18 meshes with the gear spur 9, converting the reciprocating rotation into the up-and-down reciprocating movement of the spline rod 10 along the spline sleeve 8, causing the stirring rack 19 to rotate. While rotating, the heating element moves up and down, covering different depths of tank 1. Combined with sterile oxygen supplied through oxygen supply pipe 22, it achieves efficient gas-liquid mixing. Control console 27 adjusts the spectrum type and intensity of the ring light 28 to increase the acid production rate. Temperature, pH, and dissolved oxygen sensors collect real-time data on temperature, pH, and dissolved oxygen concentration within tank 1 and transmit this data to control console 27. Control console 27 analyzes the data and automatically controls the heating plate's on / off state; it also prompts operators to adjust the pH level; and it adjusts the oxygen supply of the oxygen supply components via control console 27 to ensure the fermentation environment remains suitable, guaranteeing the normal growth and metabolism of acetic acid bacteria.
