Description

Technical Field

[0001] The present invention relates to the technical field of food fermentation, in particular to a high-efficiency and uniform fermentation device for food processing. Background Art

[0002] Fermented foods refer to foods processed and made using beneficial microorganisms. They possess unique flavors, such as yogurt, cheese, fermented glutinous rice, kimchi, soy sauce, vinegar, rice wine, beer, and wine. The current winemaking process involves placing pre-treated grapes into a sealed container, adding a predetermined amount of brewer's yeast, and then sealing the container. As fermentation progresses, gases such as carbon dioxide produced by the yeast gradually rise, causing the grape skins to form a cap and float on the surface of the liquid. To ensure the quality of the wine, regular capping is required to press the floating grape skins back into the liquid, allowing pigments, tannins, and other substances in the grape skins to fully dissolve. Currently, capping requires staff to open the sealed container and use a specialized capping device to press the grape skins. This process allows air to enter the sealed container, exposing substances in the grape skins to air, increasing the risk of oxidation and affecting the quality of the wine. Summary of the Invention

[0003] The present invention provides a high-efficiency uniform fermentation device for food processing, which can overcome certain defects of the prior art.

[0004] According to the present invention, an efficient and uniform fermentation device for food processing includes a device body, which includes a tank body and a drive assembly. An inner tank is formed inside the tank body, and a stirring mechanism that cooperates with the drive assembly is provided in the inner tank. The drive assembly is used to drive the stirring mechanism to rotate.

[0005] The stirring mechanism includes a first piston disc that cooperates with the inner wall of the inner tank. The first piston disc is provided with a cylinder along the axis. An air cavity is formed in the cylinder. The air cavity has an opening that opens downward. A trigger assembly and a pressure sensor are provided in the air cavity. The trigger assembly is used to close the opening. The pressure sensor is used to send a start instruction to the controller when gas pushes the trigger assembly.

[0006] An air port is provided at the air cavity, and an exhaust component is provided at the air port, and the exhaust component is used to discharge the gas in the air cavity; wherein, when the trigger component is in a closed state with respect to the opening, the air port is located above the trigger component.

[0007] The present invention discloses an efficient and uniform fermentation device for food processing. Gases such as carbon dioxide generated during the fermentation process rise. When the gas enters the air cavity and pushes the trigger component, the pressure sensor sends a start instruction to the controller. After receiving the instruction, the controller activates the drive component, so that the stirring mechanism can automatically stir the grape mixture inside the inner tank according to the gas generated by the fermentation. There is no need for manual regular capping operations, ensuring the efficient progress of the fermentation process. At the same time, the traditional capping operation requires opening the sealed container, causing outside air to be injected, increasing the risk of oxidation of substances in the grape skin. The present device replaces part of the traditional capping operation with the stirring action of the stirring mechanism. It can achieve a similar capping effect without opening the sealed container, reducing the chance of grape skins coming into contact with air and the risk of substance oxidation, which is conducive to ensuring the quality of brewed wine.

[0008] It is understood that the exhaust assembly can exhaust the gas in the air cavity when the gas reaches a certain level. This helps maintain the air pressure balance in the inner tank, avoids excessive pressure in the inner tank due to excessive gas, and ensures the safety and stability of the fermentation process.

[0009] Preferably, the trigger assembly includes a baffle slidably arranged in the air cavity, and a spring is provided between the baffle and the air cavity, and the spring is used to provide an elastic force to keep the baffle pressed toward the opening.

[0010] The sliding of the baffle is detected by a pressure sensor, which converts this signal into an electrical signal and sends a start command to the controller. During wine fermentation, when the pressure in the air chamber reaches a certain level, causing the baffle to slide, the controller activates the stirring mechanism to stir the wine while the exhaust assembly exhausts the gas.

[0011] Specifically, when the gas pressure is too high, the baffle is pushed up and the spring is compressed. When the bottom of the baffle exceeds the bottom of the gas port, the gas is discharged through the gas port. When the pressure drops, the spring rebounds and the baffle recloses the opening, which helps to maintain the pressure in the inner tank stable, avoid damage to the inner tank due to excessive pressure, and create a stable environment for fermentation.

[0012] Preferably, an annular groove is formed on the top wall of the first piston disc, a mounting ring is rotatably provided on the groove, a cavity is formed between the mounting ring and the groove, the exhaust assembly includes a connecting pipe for connecting the air port and the cavity, and an air pipe is provided on the top wall of the tank body and connected to the mounting ring and connected to the cavity, a one-way air valve is provided on the air pipe, and the one-way air valve is used to discharge the gas in the air cavity in one direction.

[0013] By arranging a rotatable mounting ring at the groove of the top wall of the first piston disc and forming a cavity with the groove, a gas discharge cavity is formed in combination with the connecting pipe and the air pipe, so that when the first piston disc rotates, the air pipe can still discharge the gas in the cavity.

[0014] The setting of the one-way air valve ensures that the gas can only be discharged from the air cavity through the air pipe in one direction, avoiding the overpressure that may be caused by gas accumulation in the inner tank, and also preventing external gas from flowing back into the tank body, thereby improving the safety of the brewing process.

[0015] Preferably, a water storage cavity is formed between the inner wall of the tank body and the inner tank, the water storage cavity is filled with liquid, and a constant temperature component is provided in the water storage cavity, and the constant temperature component is used to heat the liquid.

[0016] The water storage chamber formed between the inner wall of the tank and the inner tank, and the liquid filled therein, provide a stable heat conduction medium for the constant temperature component. By heating the liquid in the water storage chamber, the constant temperature component can evenly transfer heat, ensuring that the temperature of various parts of the inner tank remains consistent, avoiding local overheating or overcooling, and can achieve temperature control of the wine or fermentation materials in the inner tank.

[0017] Preferably, a liquid cavity is formed above the air cavity, and a second piston disc is slidably provided in the liquid cavity. A rotating shaft that passes through the cylinder body and the tank body is formed at the top wall of the second piston disc. A spline portion is formed on the outer wall of the rotating shaft located inside the inner tank, and a spline groove that cooperates with the spline portion is formed on the top wall of the cylinder body.

[0018] By arranging the rotating shaft, the spline portion and the spline groove, the rotating shaft can synchronously drive the cylinder to rotate when rotating, thereby facilitating stirring in the inner tank.

[0019] Preferably, the rotating shaft is connected to the output end of the driving assembly, and a circumferentially distributed wave groove is formed on the inner wall of the inner tank, and a convex portion that cooperates with the wave groove is formed on the outer wall of the first piston disc. The wave groove is used to drive the first piston disc to rotate and move up and down along the wave groove when the driving assembly drives the rotating shaft to rotate.

[0020] When the driving assembly drives the rotating shaft to rotate, the first piston disc not only rotates with the rotating shaft, but also moves up and down along the wave groove, so that the stirring arm can move back and forth in the height direction, further improving the stirring effect.

[0021] Preferably, a liquid inlet is formed on the inner wall of the liquid cavity, and a drug administration component is provided at the liquid inlet. The drug administration component includes an addition tank provided on the top wall of the tank body for containing the medicine and an infusion tube connecting the addition tank and the liquid inlet.

[0022] By providing the dosing component, medicine can be conveniently added to the liquid cavity during the brewing process, and air will not enter the liquid cavity when dosing, reducing the risk of oxidation of the substances therein.

[0023] It can be understood that there is no need to set up an additional pumping mechanism to replenish the medicine, which improves the practicality of the device.

[0024] Preferably, a liquid outlet is formed on the inner wall of the liquid cavity, a delivery pipe is provided at the liquid outlet, a stirring arm is provided at the delivery pipe and is in contact with the inner wall of the inner tank, and a plurality of penetration holes are formed on the outer wall of the delivery pipe.

[0025] Through the above structure, the device can add the medicine while stirring, further improving the fermentation effect.

[0026] Preferably, a second one-way valve is provided in the delivery tube, and a first one-way valve is provided in the infusion tube. The second one-way valve is used to discharge the liquid in the liquid cavity in one direction, and the first one-way valve is used to discharge the medicine in the addition tank in one direction into the air cavity.

[0027] By setting the second one-way valve and the first one-way valve, the first piston disc moves back and forth up and down while rotating, thereby causing the second piston disc to move back and forth in the liquid cavity, so that the medicine in the addition tank can be drawn into the liquid cavity and pressed into the inner tank through the delivery pipe, and the medicine can be delivered without opening the inner tank.

[0028] Preferably, an extension portion is formed on the top wall of the baffle and extends through the air cavity into the liquid cavity. A movable disk located in the liquid cavity is provided on the extension portion, and a vertebral body is formed on the top wall of the movable disk.

[0029] Through the above structure, when the baffle moves, it can drive the movable plate to move upward, so that the movable plate can reduce the liquid cavity space, and then discharge the residual medicine in the liquid cavity through the delivery tube, thereby improving the utilization rate of the medicine.

[0037] In order to further understand the content of the present invention, the present invention is described in detail with reference to the embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0038] Example 1

[0039] See also Figure 1-6 This embodiment provides a high-efficiency uniform fermentation device for food processing, which includes a device body 100, which includes a tank body 110 and a drive assembly 250. An inner tank 210 is formed inside the tank body 110, and a stirring mechanism 240 that cooperates with the drive assembly 250 is provided in the inner tank 210. The drive assembly 250 is used to drive the stirring mechanism 240 to rotate;

[0040] The stirring mechanism 240 includes a first piston disc 350 that cooperates with the inner wall of the inner tank 210. The first piston disc 350 is provided with a cylinder 410 along the axis. The cylinder 410 defines an air cavity 430. The air cavity 430 has an opening 411 that opens downward. A trigger assembly and a pressure sensor are provided in the air cavity 430. The trigger assembly is used to close the opening 411. The pressure sensor is used to send a start command to the controller when gas pushes the trigger assembly.

[0041] An air port 610 is provided at the air cavity 430 , and an exhaust component is provided at the air port 610 , which is used to discharge the gas in the air cavity 430 ; wherein, when the trigger component is in a closed state with respect to the opening 411 , the air port 610 is located above the trigger component.

[0042] The present invention discloses an efficient and uniform fermentation device for food processing. Gases such as carbon dioxide generated during the fermentation process rise. When the gas enters the air cavity 430 and pushes the trigger assembly, the pressure sensor sends a start command to the controller. After receiving the command, the controller activates the drive assembly 250, allowing the stirring mechanism 240 to automatically stir the grape mixture inside the inner tank 210 according to the gas production during fermentation. This eliminates the need for manual periodic capping operations, ensuring efficient fermentation. Meanwhile, the traditional capping operation requires opening the sealed container, which causes outside air to enter and increases the risk of oxidation of substances within the grape skins. The present device replaces part of the traditional capping operation with the stirring action of the stirring mechanism, achieving a similar capping effect without opening the sealed container. This reduces the chance of grape skins coming into contact with air, reduces the risk of substance oxidation, and helps ensure the quality of the wine.

[0043] It is understood that, through the provision of the exhaust assembly, when the gas in the air cavity 430 reaches a certain amount, the exhaust assembly can exhaust the gas in the air cavity 430. This helps to maintain the air pressure balance in the inner tank 210, avoid excessive pressure in the inner tank 210 due to excessive gas, and ensure the safety and stability of the fermentation process.

[0044] In this embodiment, the trigger assembly includes a baffle 460 slidably disposed in the air cavity 430 , and a spring 470 is disposed between the baffle 460 and the air cavity 430 . The spring 470 is used to provide an elastic force to keep the baffle 460 pressed toward the opening 411 .

[0045] The sliding of baffle 460 is sensed by a pressure sensor, which converts this signal into an electrical signal and sends a start command to the controller. During wine fermentation, when the pressure in air chamber 430 reaches a certain level, causing baffle 460 to slide, the controller activates stirring mechanism 240 according to the command to stir the wine while the exhaust assembly exhausts the gas.

[0046] Specifically, when the gas pressure is too high, the baffle 460 is pushed up and the spring 470 is compressed. When the bottom of the baffle 460 exceeds the bottom of the gas port 610, the gas is discharged through the gas port 610; when the pressure drops, the spring 470 rebounds and causes the baffle 460 to re-close the opening 411, which helps to maintain the pressure in the inner tank 210 stable, avoid damage to the inner tank 210 due to excessive pressure, and create a stable environment for fermentation.

[0047] In this embodiment, a ring-shaped groove 630 is formed at the top wall of the first piston disc 350, and a mounting ring 640 is rotatably provided at the groove 630. A cavity is formed between the mounting ring 640 and the groove 630. The exhaust component includes a connecting pipe 620 for connecting the air port 610 and the cavity, and an air pipe 510 provided at the top wall of the tank body 110 and connected to the mounting ring 640 and connected to the cavity. A one-way air valve 520 is provided at the air pipe 510, and the one-way air valve 520 is used to discharge the gas in the air cavity 430 in one direction.

[0048] By setting a rotatable mounting ring 640 at the groove 630 on the top wall of the first piston disc 350, and forming a cavity with the groove 630, combined with the connecting pipe 620 and the air pipe 510, a gas discharge cavity is formed, so that when the first piston disc 350 rotates, the air pipe 510 can still discharge the gas in the cavity.

[0049] The setting of the one-way air valve 520 ensures that the gas can only be discharged from the air cavity 430 through the air pipe 510 in one direction, avoiding the overpressure situation that may be caused by gas accumulation in the inner tank 210, and also preventing external gas from flowing back into the tank body 110, thereby improving the safety of the brewing process.

[0050] In this embodiment, a water storage chamber 220 is formed between the inner wall of the tank body 110 and the inner tank 210. The water storage chamber 220 is filled with liquid. A constant temperature component 230 is provided in the water storage chamber 220. The constant temperature component 230 is used to heat the liquid.

[0051] The water storage chamber 220 formed between the inner wall of the tank body 110 and the inner tank 210, and the liquid filled therein, provide a stable heat conduction medium for the constant temperature component 230. By heating the liquid in the water storage chamber 220, the constant temperature component 230 can evenly transfer heat, ensuring that the temperature of various parts of the inner tank 210 remains consistent, avoiding local overheating or overcooling, and thus achieving temperature control of the wine or fermentation materials in the inner tank 210.

[0052] Example 2

[0053] Seen in Figure 2-6 This embodiment also provides a high-efficiency uniform fermentation device for food processing, which differs from Example 1 in that a liquid cavity 420 is formed above the air cavity 430, and a second piston disc 440 is slidably provided in the liquid cavity 420. A rotating shaft 310 that passes through the cylinder 410 and the tank body 110 is formed at the top wall of the second piston disc 440, and a spline portion 330 is formed on the outer wall of the rotating shaft 310 located inside the inner tank 210, and a spline groove that cooperates with the spline portion 330 is formed on the top wall of the cylinder 410.

[0054] By configuring the rotating shaft 310 , the spline portion 330 and the spline groove, the rotating shaft 310 can synchronously drive the cylinder 410 to rotate when rotating, thereby facilitating stirring of the inner tank 210 .

[0055] In this embodiment, the rotating shaft 310 is connected to the output end of the driving assembly 250, and a circumferentially distributed wave groove is formed on the inner wall of the inner tank 210. A convex portion that cooperates with the wave groove is formed on the outer wall of the first piston disc 350. The wave groove is used to drive the first piston disc 350 to rotate while moving up and down along the wave groove when the driving assembly 250 drives the rotating shaft 310 to rotate.

[0056] When the driving assembly 250 drives the rotating shaft 310 to rotate, the first piston disc 350 not only rotates with the rotating shaft 310, but also moves up and down along the wave groove, so that the stirring arm 370 can reciprocate in the height direction, further improving the stirring effect.

[0057] In this embodiment, a liquid inlet 422 is formed on the inner wall of the liquid cavity 420, and a drug delivery component is provided at the liquid inlet 422. The drug delivery component includes an addition tank 340 for holding the medicine provided on the top wall of the tank body 110 and an infusion tube 341 connecting the addition tank 340 and the liquid inlet 422.

[0058] By providing the dosing assembly, it is possible to conveniently add medicine to the liquid cavity during the brewing process, and it can be ensured that air does not enter the liquid cavity 420 when dosing, thereby reducing the risk of oxidation of the substances therein.

[0059] It can be understood that there is no need to set up an additional pumping mechanism to replenish the medicine, which improves the practicality of the device.

[0060] In this embodiment, a liquid outlet 421 is formed on the inner wall of the liquid cavity 420, a delivery pipe 360 is provided at the liquid outlet 421, a stirring arm 370 is provided at the delivery pipe 360 and is in contact with the inner wall of the inner tank 210, and a plurality of penetration holes are formed on the outer wall of the delivery pipe 360.

[0061] Through the above structure, the device can add the medicine while stirring, further improving the fermentation effect.

[0062] In this embodiment, a second one-way valve 490 is provided in the delivery tube 360, and a first one-way valve 450 is provided in the infusion tube 341. The second one-way valve 490 is used to discharge the liquid in the liquid cavity 420 in one direction, and the first one-way valve 450 is used to discharge the medicine in the addition tank 340 into the air cavity 430 in one direction.

[0063] By setting the second one-way valve 490 and the first one-way valve 450, the first piston disc 350 moves back and forth up and down while rotating, so that the second piston disc 440 moves back and forth in the liquid chamber 420, and then the medicine in the addition tank 340 can be drawn into the liquid chamber 420 and pressed into the inner tank 210 through the delivery pipe 360, and the medicine can be delivered without opening the inner tank 210.

[0064] In this embodiment, an extension portion is formed on the top wall of the baffle 460 and extends through the air cavity 430 into the liquid cavity 420. A movable disk 480 is provided in the liquid cavity 420 at the extension portion, and a cone portion is formed on the top wall of the movable disk 480.

[0065] Through the above structure, when the baffle 460 moves, it can drive the movable plate 480 to move upward, so that the movable plate 480 can reduce the space of the liquid cavity 420, and then discharge the residual medicine in the liquid cavity 420 through the delivery tube 360, thereby improving the utilization rate of the medicine.

[0066] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on one or several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the scope of protection of the present application.

[0067] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The embodiments shown in the embodiments are only part of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the above and, without departing from the purpose of the present invention, designs a structure and embodiment similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
