Description

Technical Field

[0001] This utility model relates to the technical field of vinegar brewing, specifically to a fermentation heating device for vinegar brewing. Background Technology

[0002] Vinegar, with its sour and mellow taste and fragrant and mild aroma, is an indispensable condiment in cooking. Its main components are acetic acid and higher alcohols. Vinegar is primarily made from rice or sorghum. Proper fermentation converts liquids containing carbohydrates (sugar, starch) into alcohol and carbon dioxide. The alcohol then combines with oxygen in the air under the action of certain bacteria to produce acetic acid and water. Therefore, the vinegar-making process is essentially the further oxidation of alcohol into acetic acid. The vinegar-making process requires containers for storage, necessitating a fermentation tank.

[0003] Utility model patent CN215517354U discloses a fermentation tank for vinegar brewing with temperature control capabilities, belonging to the technical field of vinegar brewing. It addresses the problem of existing technologies lacking temperature control, making it difficult to accurately control the temperature inside the tank during brewing. This leads to brewing failures due to excessively high or low temperatures, increasing raw material waste. The tank includes a base with the fermentation tank body fixedly mounted on top; a feed inlet fixedly mounted above the fermentation tank body; an air pump mounted to the right of the feed inlet; and a cold water tank mounted at the rear end of the fermentation tank body. This temperature-controlled fermentation tank for vinegar brewing, compared with existing devices, can detect the internal temperature of the fermentation tank in real time through temperature detection components. Cold water from the cold water tank can be transported to the cooling chamber through water injection pipes, thereby reducing the temperature of the cooling chamber and thus cooling the inside of the fermentation tank. Heating components can heat the heating chamber, and the heated chamber can transfer the temperature to the inside of the fermentation tank, thereby raising the temperature of the fermentation tank and thus achieving temperature controllability.

[0004] However, the above patent still has shortcomings: although the patent can stir the raw materials for vinegar making, it cannot enable the raw materials for vinegar making inside the device to circulate up and down. As a result, when the raw materials are fermenting, the temperature inside and at the bottom of the raw materials is much higher than at the top, which makes the internal temperature of the raw materials for vinegar making inconsistent and prone to rancidity or off-flavors. Utility Model Content

As a result, during the fermentation of the raw materials for vinegar brewing, the temperature inside and at the bottom of the raw materials is much higher than that at the top, which makes the internal temperature of the raw materials for vinegar brewing inconsistent and easily leads to problems such as rancidity or off-flavors.

[0027] like Figure 4 As shown, the stirring mechanism 7 includes: a rotating pipe 6 located inside the fermentation tank 2, with threaded ribbons 9 on both sides, the ribbons 9 being adapted to the fermentation tank 2; stirring rods 10 fixedly connected to both ends of the ribbons 9; the stirring rods 10 being fixedly connected to the rotating pipe 6 via first fixing rings 11; a second fixing ring 12 is provided at the top of one of the first fixing rings 11, the second fixing ring 12 being fixed to the outer surface of the rotating pipe 6; anchor-type stirring blades 13 are fixedly connected to both sides of the second fixing ring 12, the anchor-type stirring blades 13 cooperating with the ribbons 9 and the stirring rods 10; a first synchronous pulley 14 is fixedly connected to the outer surface of the rotating pipe 6 located outside the fermentation tank 2; the first synchronous pulley 14 is connected to a second synchronous pulley 16 via a synchronous belt 15; a rotating shaft 17 is fixedly connected to the center of the second synchronous pulley 16; the rotating shaft 17... The top end passes through the fixing frame 33 and extends to the motor 18. The motor 18 is fixedly connected to the fixing frame 33, and the fixing frame 33 is fixedly connected to the fermentation tank 2. The rotating shaft 17 is fixedly connected to the output end of the motor 18. When the motor 18 is started, the output end of the motor 18 drives the rotating shaft 17.

[0028] like Figures 2 to 4As shown, the oxygenation mechanism 8 includes: a support frame 19 rotatably connected to the outer surface of the top of the rotating pipe 6, the support frame 19 being fixedly connected to the fermentation tank 2; four oxygenation discs 20 are uniformly fixedly connected to the outer surface of the rotating pipe 6 inside the fermentation tank 2; a plurality of oxygenation holes 21 are uniformly opened on the outer surface of the oxygenation discs 20; a filter screen 22 is fixedly connected to the inner wall of the oxygenation discs 20, and the filter screen 22 cooperates with the oxygenation holes 21; a connector 23 is fixedly connected to the support frame 19 near the rotating pipe 6.

When the air pump 25 is started, the air pump 25 draws external control and delivers air through the air supply pipe 24 and the connector 23 to the interior of the oxygenation plate 20. Then, the air is delivered to the interior of the raw material through the filter screen 22 and the oxygenation hole 21, thereby oxygenating the bacteria inside the raw material.

[0029] like Figure 5 As shown, a spiral heating tube 26 is installed inside the heating tank 3. The heating tube 26 is fixed to the outer surface of the fermentation tank 2. A temperature sensor 27 is installed on one side of the support frame 19.

[0033] Working principle: Starting motor 18 drives shaft 17, which in turn drives second synchronous pulley 16. Second synchronous pulley 16 drives first synchronous pulley 14 via synchronous belt 15. First synchronous pulley 14 drives rotating pipe 6, which in turn drives first fixed ring 11 and second fixed ring 12. First fixed ring 11, while rotating, drives screw ribbon 9 via stirring rod 10. Screw ribbon 9 continuously transports the raw material from the bottom of fermentation tank 2 to the top, causing the raw material to circulate up and down inside fermentation tank 2. Meanwhile, second fixed ring 12... The anchor-type stirring blade 13 agitates the raw materials, allowing for vertical circulation of the raw materials within the device. This ensures a more uniform temperature inside the raw materials, preventing spoilage or off-flavors. This addresses the problem that existing fermentation heating devices for vinegar production, while capable of agitating the raw materials, lack vertical circulation, resulting in inconsistent temperatures at the bottom and inside of the raw materials during fermentation, which can easily lead to spoilage or off-flavors.

[0034] The air pump 25 is started. The air pump 25 draws in external control and delivers air through the air supply pipe 24 and connector 23 to the interior of the oxygenation plate 20. Then, the air is delivered to the interior of the raw material through the filter screen 22 and oxygenation hole 21, thereby oxygenating the microbial community inside the raw material. This can supply a large amount of oxygen to the raw material inside the device, which is conducive to the reproduction and survival of microorganisms, improves the quality of the finished product, and solves the problem that the existing fermentation heating device for vinegar brewing cannot supply oxygen to the interior and bottom of the raw material, affecting the reproduction and survival of microorganisms and resulting in poor quality of the finished product.
