Description

Technical Field

[0001] This utility model relates to a fermentation device, specifically a fermentation device for plum production, belonging to the technical field of plum production equipment. Background Technology

[0002] Preserved plums are a popular snack, prized for their sweet and sour taste and moderate saltiness. Long-term consumption is believed to have benefits such as strengthening the stomach, astringing the lungs, warming the spleen, stopping bleeding, reducing phlegm, reducing swelling, detoxifying, and quenching thirst. Currently, some manufacturers are fermenting preserved plums during production to enhance their flavor and acidity, making them even more delicious and thirst-quenching. However, the market lacks specialized equipment for preserved plum fermentation, resulting in high costs and inconsistent fermentation quality.

[0003] Chinese patent CN210736745U discloses a fermentation device for plum production, including a lower tank and an upper tank. The upper tank has a bowl-shaped groove vertically connected to the top center, which is wider at the top and narrower at the bottom. Although this application uses a rotating shaft to drive a stirring paddle to stir the plums inside the tank, making them mix more evenly with the fermentation agent and improving the efficiency and quality of fermentation, this application only uses the paddle for unidirectional stirring. This not only results in low mixing efficiency, but also makes it difficult to stir the plums deposited at the bottom of the tank. This leads to poor mixing between the plums at the bottom and the fermentation agent, resulting in a decrease in the overall fermentation effect.

[0004] Therefore, a fermentation device for plum production is proposed here. Utility Model Content

[0005] This invention proposes a fermentation device for plum production to solve the problems of low mixing efficiency of unidirectional stirring in the prior art, and difficulty in stirring the plums deposited at the bottom of the tank, resulting in poor mixing effect between the plums at the bottom and the fermentation agent, thus reducing the overall fermentation effect.

[0006] This utility model is achieved through the following technical solution: a fermentation device for plum production, including a tank and a heat exchange tube sleeved on the outer surface of the tank. A pressure relief component is also fixed on the upper surface of the tank. A stirring component and a bottom mixing component are also installed inside the tank. The bottom mixing component moves inside the tank through the stirring component.

[0007] The stirring assembly includes a fixed sleeve fixed to the upper surface of the tank, a motor is sleeved inside the fixed sleeve, a first bevel gear is fixed to the output shaft of the motor, a first stirring rod is provided on the side of the motor, a fermentation chamber is opened inside the tank, the lower end of the first stirring rod is rotatably connected to the inner wall of the fermentation chamber, and a second bevel gear is fixed to the top of the first stirring rod, and the first bevel gear meshes with the second bevel gear.

[0008] Furthermore, the stirring assembly also includes a second stirring rod sleeved on the surface of the first stirring rod, a stirring paddle fixed on the surface of the second stirring rod, the lower end of the second stirring rod passing through the inside of the fermentation chamber, a side scraper fixed on the side of the first stirring rod, and a third bevel gear fixed on the surface of the second stirring rod, the first bevel gear meshing with the third bevel gear.

[0009] Furthermore, a support rod is fixed to the side of the first stirring rod, and a first auger is rotatably connected to the surface of the support rod. A spur gear is fixed to the upper end of the first auger, and a toothed plate is fixed to the inner wall of the fermentation chamber. The spur gear meshes with the toothed plate. There are two support rods, two first augers, and two spur gears, and they are symmetrically arranged on both sides of the first stirring rod.

[0010] Furthermore, the bottom mixing assembly includes a housing fixed to the inner wall of the fermentation chamber, the lower end of the first stirring rod passing through the inside of the housing, and a second auger passing through the side of the housing, one end of the second auger being rotatably connected to the inner wall of the fermentation chamber.

[0011] Furthermore, a fourth bevel gear is fixed to the other end of the second auger, and a fifth bevel gear is fixed to the lower end of the first stirring rod, with the fourth bevel gear meshing with the fifth bevel gear.

[0014] This utility model provides a fermentation device for plum production, which has the following beneficial effects:

[0015] The fermentation device for plum production uses a motor to drive the first bevel gear to rotate, which in turn drives the second and third bevel gears to rotate. This causes the first and second stirring rods to rotate synchronously in opposite directions, generating stronger shear and flow during the stirring process. This promotes full contact between the raw materials, thereby improving mixing efficiency, effectively avoiding dead corners in the mixing container, ensuring that each area is fully stirred, reducing the uneven distribution of components during fermentation, and improving the fermentation quality of the plums.

[0016] This fermentation device for plum production can effectively stir the plums deposited at the bottom of the tank through the bottom mixing group, which can promote the contact between the fermentation agent and the bottom deposited plums, so that they are evenly mixed with the fermentation agent, thereby accelerating the fermentation process, improving acid production efficiency and overall fermentation effect. In addition, the mixing also helps the gas dispersion, enhances oxygen transmission, and is conducive to aerobic fermentation. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0030] Please see Figures 1-5 The present invention proposes the following implementation scheme: a fermentation device for plum production, including a tank 1 and a heat exchange tube 4 sleeved on the outer surface of the tank 1. A pressure relief component 5 is also fixed on the upper surface of the tank 1. A stirring component 2 and a bottom mixing component 3 are also installed inside the tank 1. The bottom mixing component 3 moves inside the tank 1 through the stirring component 2.

[0031] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4 The stirring assembly 2 includes a fixing sleeve 201 fixed to the upper surface of the tank 1. A motor 202 is fitted inside the fixing sleeve 201. A first bevel gear 203 is fixed to the output shaft of the motor 202. A first stirring rod 204 is provided on the side of the motor 202. A fermentation chamber 101 is opened inside the tank 1. The lower end of the first stirring rod 204 is rotatably connected to the inner wall of the fermentation chamber 101. A second bevel gear 205 is fixed to the top of the first stirring rod 204, and the first bevel gear 203 meshes with the second bevel gear 205. The stirring assembly 2 also includes a second stirring rod 206 fitted onto the surface of the first stirring rod 204. A stirring paddle 2061 is fixed to the surface of the second stirring rod 206. The lower end of the second stirring rod 206 passes through the interior of the fermentation chamber 101. A side scraper 2041 is fixed to the side of the first stirring rod 204. A third bevel gear 207 is fixed to the surface of the second stirring rod 206, and the first bevel gear 203 meshes with the third bevel gear 207. The first stirring rod 204 also has... A support rod 2042 is fixed, and a first auger 2043 is rotatably connected to the surface of the support rod 2042. A spur gear 2044 is fixed to the upper end of the first auger 2043. A toothed plate 102 is fixed to the inner wall of the fermentation chamber 101. The spur gear 2044 meshes with the toothed plate 102. There are two support rods 2042, two first augers 2043, and two spur gears 2044, which are symmetrically arranged on both sides of the first stirring rod 204. The fermentation device for plum production drives the first bevel gear 203 to rotate through the motor 202. The first bevel gear 203 drives the second bevel gear 205 and the third bevel gear 207 to rotate, thereby causing the first stirring rod 204 and the second stirring rod 206 to rotate synchronously in opposite directions. During the stirring process, stronger shearing and flow are generated, which promotes full contact between raw materials, thereby improving mixing efficiency, effectively avoiding dead corners in the mixing container, ensuring that each area is fully stirred, reducing the uneven distribution of components during fermentation, and improving the fermentation quality of plums.

[0032] Please refer to this carefully. Figure 2 , Figure 3 and Figure 5 The bottom mixing assembly 3 includes a housing 301 fixed to the inner wall of the fermentation chamber 101. The lower end of the first stirring rod 204 passes through the inside of the housing 301, and a second auger 302 passes through the side of the housing 301. One end of the second auger 302 is rotatably connected to the inner wall of the fermentation chamber 101. A fourth bevel gear 303 is fixed to the other end of the second auger 302, and a fifth bevel gear 304 is fixed to the lower end of the first stirring rod 204. The fourth bevel gear 303 and the fifth bevel gear 304 mesh with each other. This fermentation device for plum production can effectively stir the plums deposited at the bottom of the tank through the bottom mixing assembly, which can promote the contact between the fermentation agent and the plums deposited at the bottom, so that they are evenly mixed with the fermentation agent, thereby accelerating the fermentation process, improving the acid production efficiency and the overall fermentation effect. In addition, the mixing also helps the gas dispersion, enhances the oxygen transmission, and is conducive to the aerobic fermentation.

[0033] Please refer to this carefully. Figure 1 and Figure 3 The pressure relief assembly 5 includes an exhaust pipe 501 that passes through the upper surface of the pipe body. A cover plate 502 overlaps the upper surface of the exhaust pipe 501. A telescopic rod 503 is fixed to the lower surface of the cover plate 502. The lower end of the telescopic rod 503 is fixed to the upper surface of the tank body 1. A spring 504 is also sleeved on the surface of the telescopic rod 503. There are two telescopic rods 503 and two springs 504, which are symmetrically arranged on both sides of the cover plate 502. A feed pipe 7 passes through the upper surface of the tank body 1. A discharge pipe 6 passes through the side of the tank body 1. A solenoid valve is installed on the surface of the discharge pipe 6.

[0034] In use, this invention involves first placing the device in a designated location and connecting it to an external control device and a 220V mains power supply. The control device can be a conventional, known device such as a computer. Then, the operator controls the motor 202 via the control device. The motor 202 drives the first bevel gear 203 to rotate, which in turn drives the second bevel gear 205 to rotate. The second bevel gear 205 then drives the first stirring rod 204 to rotate. The first stirring rod 204 drives the side scraper 2041 and the first auger 2043, both fixed to its side, to rotate. The system can scrape off the preserved plums and fermentation agents adhering to the inner wall of the fermentation chamber 101. Since the gear fixed at the top of the first auger 2043 meshes with the toothed plate 102, the first auger 2043 can rotate on its own while following the rotation of the first stirring rod 204, thereby conveying the preserved plums at the bottom back to the top. At the same time, the first bevel gear 203 drives the third bevel gear 207 to rotate, the third bevel gear 207 drives the second stirring rod 206 to rotate, and the second stirring rod 206 drives the stirring paddle 2061 fixed on the side to rotate, thereby mixing the preserved plums and fermentation agents in the fermentation chamber 101.

[0035] During the rotation of the first stirring rod 204, it can drive the fifth bevel gear 304 to rotate, which in turn drives the fourth bevel gear 303 to rotate, thereby driving the second auger 302 to rotate. This effectively stirs the plums deposited at the bottom of the tank, promotes the contact between the fermentation agent and the plums deposited at the bottom, and ensures that they are evenly mixed with the fermentation agent, thereby accelerating the fermentation process and improving the acid production efficiency and overall fermentation effect.

[0036] The heat exchange tube 4 can heat the tank 1 to maintain a suitable fermentation temperature in the fermentation chamber 101. When a large amount of gas is produced during fermentation, the internal pressure of the fermentation chamber 101 becomes too high, and the gas is discharged through the exhaust pipe 501. At the same time, the telescopic rod 503 and the spring 504 can make the cover plate 502 block the exhaust pipe 501 to prevent external dust or debris from entering the fermentation chamber 101 through the exhaust pipe 501.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
