Abstract
Description
Technical Field
[0001] This application relates to the field of alcoholic beverage brewing technology, and in particular to a stirred fruit wine fermentation device. Background Technology
[0002] In traditional fruit wine brewing, fruit pomace is typically sealed together with other raw materials in a reaction vessel. Fermentation extracts fruit aromas and other substances, transforming them into the wine. This process generates a large amount of gases such as carbon dioxide, which rise to the surface as bubbles due to density differences and are released through a pressure relief mechanism at the top of the reaction vessel.
[0003] However, as the bubbles rise, they exert a pushing force on the pomace. When the pushing force that pushes the pomace upward is greater than the resistance that causes the pomace to sink, the pomace will continue to move upward and form a surface accumulation, causing the pulp to float or even float to the surface of the liquid. This prevents the pulp from fermenting fully and affects the brewing of fruit wine.
[0004] To address the above issues, the traditional solution is to open the reactor and push down the fruit pomace floating on the liquid surface to force it to settle. However, opening the reactor is not only relatively troublesome, but also makes it easier for outside air to enter the reactor, affecting the fermentation process. Therefore, this application proposes a new technical solution. Utility Model Content
[0005] In order to facilitate the settling of fruit pomace floating on the liquid surface in a relatively enclosed space, this application provides a stirred fruit wine fermentation device.
[0006] This application provides a stirred fruit wine fermentation device, which adopts the following technical solution:
[0007] A stirring fruit wine fermentation device includes a tank, a cover that fits over the top of the tank, and a pressure relief mechanism fixed to the cover.

The rotating shaft penetrates the cover vertically, and the cover is equipped with a drive unit for driving the rotating shaft to rotate. The spiral blade is fixed to the rotating shaft in a spiral shape, and the blade width of the spiral blade gradually decreases from the top to the bottom.
[0008] The pressure relief mechanism includes a one-way valve, with the valve facing upward and a test control mechanism above it for assisting in observing the amount of carbon dioxide gas discharged.

One end of the spring is fixed to the pressure push plate, and the other end is fixed to the inner wall of the cover. The self-resetting push button switch is installed on the inner wall of the cover with its trigger end facing the pressure push plate. The self-resetting push button switch is connected in series with the power supply circuit of the motor. A corrugated plate structure is fixed to the edge of the pressure push plate. The corrugated plate structure is arranged around the pressure push plate and its upper end is fixed to the inner wall of the cover. A manual switch is connected in parallel with the self-resetting push button switch. The manual switch is installed on the outside of the tank.
[0011] Optionally, the cover is provided with a bracket, and a placement box is provided at the top of the bracket. The placement box is located above the valve port of the one-way valve and has a through hole. The pH test paper is fixed inside the placement box, and the test end of the pH test paper is placed above the through hole of the placement box. The wetting component is located on the top of the pH test paper and abuts against the pH test paper.
[0012] Optionally, the wetting component includes an absorbent sponge and a water storage box. The absorbent sponge is in contact with the pH test paper. The placement box is rectangular in top view and has an opening at the top. The absorbent sponge is located inside the placement box.

As the spiral blade rotates, the fruit pomace floating on the liquid surface settles along the surface of the spiral blade. A sealing unit is provided between the rotating shaft and the cover to reduce the possibility of external gas entering the tank. The fruit pomace can settle in a relatively sealed environment, reducing the impact of fruit pomace floating on the fruit wine brewing process. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0023] This application discloses a stirred fruit wine fermentation device.
[0024] Reference Figure 1 and Figure 2 The stirred fruit wine fermentation device includes a tank 1, a cover 2 that fits on top of the tank 1, and a pressure relief mechanism fixed to the cover 2. The tank 1 and cover 2 are circular when viewed from above. The tank 1 is placed in the working area with multiple supports. The tank 1 is equipped with a rotary pushing mechanism 4, which assists in the settling of fruit pomace floating above the liquid surface. The rotary pushing mechanism 4 includes a rotating shaft 41 and a spiral blade 42. The rotating shaft 41 vertically penetrates the cover 2, and a sealing unit is provided between the rotating shaft 41 and the cover 2. The sealing unit can be a bearing and a corresponding shaft seal structure. The cover 2 is equipped with a drive unit 5 for driving the rotating shaft 41 to rotate. The drive unit 5 can be a (reduction) motor 53, and the output shaft of the motor 53 is fixedly connected to the rotating shaft 41 via a coupling. The spiral blade 42 spirally surrounds the rotating shaft 41, and the inner side of the blade is fixed to the rotating shaft 41. The blade width of the spiral blade 42 gradually decreases from the top to the bottom, forming a spiral downward cone shape.
[0025] The pressure relief mechanism includes a one-way valve 3, which can be a hydraulically controlled one-way valve 3, thus facilitating the control of the closure of the valve port. The valve of the one-way valve 3 is positioned upwards, and a test control mechanism 6 for assisting in the observation of the amount of carbon dioxide gas discharged is located above the valve. The test control mechanism 6 includes pH test paper and a wetting component that contacts the pH test paper. The wetting component wets the pH test paper. When carbon dioxide is discharged through the one-way valve 3, it is absorbed by the wetted pH test paper at the top. Carbon dioxide reacts with water to form an acid, so the presence of carbon dioxide can be observed by the color of the pH test paper. For example, by comparing the color of the test paper with a standard color chart, if the pH value is below 5.5 and does not recover for 30 seconds, it is determined that carbon dioxide is being discharged. Further inference suggests that the fermentation inside the tank 1 produces carbon dioxide. As the carbon dioxide rises and is discharged, it pushes the fruit pomace upwards, at which point the rotating shaft 41 can be controlled to start working, and the fruit pomace is transported below the liquid surface through the spiral blade 42.
[0026] With the above configuration, the motor 53 drives the gear set and the rotating shaft 41 to rotate, thereby causing the spiral blade 42 to rotate. As the spiral blade 42 rotates, the fruit residue floating on the liquid surface settles down along the surface of the spiral blade 42. Since a sealing unit is provided between the rotating shaft 41 and the cover 2, the fruit residue can settle in a relatively sealed environment.
[0027] By using the test control mechanism 6 above the one-way valve 3, observe whether carbon dioxide is emitted. If so, it can be inferred that fermentation is taking place inside the tank 1. Push the fruit residue upwards to make it float, and then control the motor 53 to work. This way, the motor 53 does not need to be in operation at all times, reducing energy waste.
[0028] Reference Figure 2 The drive unit 5 includes a gear set and a motor 53. The gear set includes a first gear 51 and a second gear 52. The diameter of the first gear 51 is larger than the diameter of the second gear 52. The first gear 51 is fitted and fixed to the rotating shaft 41, and the second gear 52 is fitted and fixed to the output shaft of the motor 53. The first gear 51 and the second gear 52 mesh, so that when the motor 53 rotates, it can drive the first gear 51 and the second gear 52 to rotate. Since the diameter of the first gear 51 is larger than the diameter of the second gear 52, it plays a certain role in speed reduction.
[0029] Reference Figure 3The inner side of the cover 2 is provided with a pressure push plate 21, a spring, and a self-resetting button switch. The pressure push plate 21 extends along the inner wall of the cover 2, that is, it fits the curvature of the cover 2 and is located on the side of the inner wall of the cover 2, which helps the pressure push plate 21 to press the self-resetting button switch. One end of the spring is fixed to the pressure push plate 21, and the other end is fixed to the inner wall of the cover 2. When the spring is in its natural state, the pressure push plate 21 is away from the cover 2, that is, when the spring is in its natural state, the self-resetting button switch is not pressed or triggered. The self-resetting button switch is installed on the inner wall of the cover 2 with the trigger end facing the pressure push plate 21. The self-resetting button switch is connected in series with the power supply circuit of the motor 53, so that the operation of the motor 53 can be controlled by the self-resetting button switch. A corrugated plate 22 structure is fixed to the edge of the pressure push plate 21, and the corrugated plate 22 structure is arranged around the pressure push plate 21 and the upper end is fixed to the inner wall of the cover 2.
[0030] With the above setup, when carbon dioxide and other gases are produced inside tank 1 due to fermentation, the carbon dioxide rises and fills the interior of tank 1. Since it is the initial stage of brewing, the hydraulic check valve 3 is closed, so the carbon dioxide and other gases temporarily remain inside tank 1, increasing the internal pressure. When the pressure reaches a threshold sufficient to push the pressure push plate 21, it is assumed that the pomace has risen under the upward push of the bubbles. At this point, the internal pressure of tank 1 increases, simultaneously pushing the pressure push plate 21 upward, thereby triggering the self-resetting button switch, turning on motor 53, causing the spiral blade 42 to rotate, and conveying the pomace pushed upward by the bubbles downward. If the pressure inside the tank continues to increase, the hydraulic check valve 3 will be triggered to open and release pressure.
[0031] Since the above setup will lock the gas inside the tank 1, for safety reasons, a safety valve should be added for pressure relief. When the pressure reaches a threshold that may be dangerous (i.e., excessive pressure may cause an explosion), the safety valve needs to automatically relieve the pressure, thereby further improving the safety of this application.
[0032] The self-resetting button switch is connected in parallel with a manual switch. The manual switch is installed outside the tank 1. Thus, when the air pressure inside the tank 1 is insufficient for the pressure push plate 21 or when internal parts malfunction, the motor 53 can be controlled by the external manual switch.
[0033] The cover 2 is provided with a support 61, which can be columnar and has multiple supports, which are fixed in a ring around the one-way valve 3 on the outside of the one-way valve 3. The top of the support 61 is provided with a placement box 62, which is hollow inside and open at the top. The placement box 62 is located above the valve port of the one-way valve 3 and has a through hole at the bottom. The pH test paper is fixed inside the placement box 62 and located at the bottom. The test end of the pH test paper is located above the through hole of the placement box 62. The wetting component is located on the top of the pH test paper and abuts against the pH test paper, so that the gas can be absorbed and detected by the moistened pH test paper when it is discharged.
[0034] In another embodiment of this application, in order to facilitate the absorption of gas by the moistened pH test paper, the top of the valve port of the one-way valve 3 abuts against the bottom of the placement box 62, or a transparent cover can be installed to prevent gas from escaping. The top of the transparent cover abuts against the bottom of the placement box 62, and the top of the transparent cover is open and the opening covers the through hole at the bottom of the placement box 62 to ensure that the pH test paper can come into contact with carbon dioxide. Small holes are opened on the side of the transparent cover to ensure that the gas is not discharged too quickly.
[0035] Due to the auxiliary function of the transparent cover, the gas discharged by the one-way valve 3 will remain inside the transparent cover. Since the exhaust port of the transparent cover is small, the gas inside the transparent cover will be more abundant than when there is no transparent cover, which makes it easier for the pH test paper to absorb carbon dioxide in the gas and perform detection. Moreover, the transparent material makes it easier to observe the color change of the pH test paper. Therefore, the placement box 62 can also be transparent to facilitate observation and comparison of colors.
[0036] With the above settings, when the hydraulic check valve 3 reaches the threshold for opening the valve port, gas is discharged from the valve port. The pH test paper is located above the valve port, and carbon dioxide can be detected by the moistened pH test paper. Whether carbon dioxide is discharged can be observed by replacing the pH test paper regularly. If carbon dioxide is discharged continuously, it can be inferred that fermentation is ongoing inside the tank 1, and gas is escaping and pushing the fruit residue upward. At this time, the gas inside has been discharged through the check valve 3 to relieve pressure, and it may not be possible to trigger the self-resetting button switch to rotate the spiral blade 42. In this case, the spiral blade 42 can be rotated by pressing the manual switch to help the fruit residue settle.
[0037] In another embodiment of this application, reference is made to Figure 1 The wetting component includes an absorbent sponge and a water storage box 63. The absorbent sponge is in contact with the pH test paper. The placement box 62 is rectangular in top view and open at the top. The absorbent sponge is located inside the placement box 62 and above the pH test paper. The water storage box 63 is located at the top of the absorbent sponge and is ring-shaped, which makes it easier to evenly wet the absorbent sponge. The water storage box 63 is located inside the opening of the placement box 62. The ring-shaped water storage box 63 does not fit into the rectangular placement box 62, making it easier to pick up. The side wall of the water storage box 63 is provided with multiple water outlets, and the top has a water inlet covered with a sealing cap. Thus, when water is not needed from the water storage box 63, water can remain in the water storage box 63 under atmospheric pressure. The water storage box 63 is flexible, so when needed, the water can be squeezed by hand to dispense water. As can be seen from the above, the diameter of the water storage box 63 should be smaller than the length and width of the placement box 62, so that when the placement box 62 is placed in, water will not be squeezed out due to the side wall of the water storage box 63 being squeezed against the inner wall of the placement box 62.
[0038] With the above settings, the water storage box 63 eliminates the need to frequently add water to moisten the pH test paper. The water storage box 63 is equipped with a sealing cap to keep the water inside, and the water storage box 63 is designed to be flexible so that it can be squeezed to dispense water.
[0039] Reference Figure 1 The placement box 62 is also provided with a drainage channel 64. The bottom surface of the placement box 62 is set at an angle. The drainage channel 64 is fixed at the end with a larger angle, that is, at the end with a lower height of the placement box 62, so that excess water can be discharged through the drainage channel 64. The drainage channel 64 is open at both ends and open at the top. A wastewater box 65 is provided at the bottom of the drainage channel 64 away from the opening of the placement box 62. The wastewater box 65 is located directly below the opening of the drainage channel 64. When water flows out, it can be automatically discharged into the wastewater box 65. The wastewater box 65 can be cleaned periodically.
[0040] With the above settings, if too much water comes out when the water storage box 63 is squeezed, some of the excess water can be diverted into the drainage channel 64 by the inclination of the placement box 62, and then discharged through the drainage channel 64. This reduces the possibility of excessive moisture or even leakage of the pH test paper. The water content is sufficient but not excessive, which further ensures the accuracy of the test and effectively prevents the concentration of carbon dioxide in the water from decreasing due to excessive moisture. This improves the accuracy of the pH test paper test and further optimizes the solution.
[0041] Reference Figure 1 The absorbent sponge is angled against one side of the bottom surface of the placement box 62, and the angle matches the angle of the bottom surface of the placement box 62. The upper part of the absorbent sponge is horizontal, so the water storage box 63 is also horizontal when placed on top of the absorbent sponge. This effectively prevents the water storage box 63 from being placed at an angle. However, when the water storage box 63 is not full, some of the water outlets are not sealed, causing air to enter the interior. This prevents the water from being locked in the water storage box 63, effectively preventing the water storage box 63 from automatically discharging and leaking water.
[0042] Reference Figure 1 and Figure 2 This application also includes a cleaning component, which includes a scraper and a fixing frame 7. The height of the fixing frame 7 should be greater than at least two-thirds of the height of the tank 1 or greater than the height of the wine during brewing in most cases. The scraper is adhered to the fixing frame 7 and one side of the scraper abuts against the inner wall of the tank 1. The side of the fixing frame 7 near the inner wall of the tank 1 is the same length as the scraper, thereby facilitating the fixing of the scraper. One end of the fixing frame 7 is fixed to the rotating shaft 41. The end of the fixing frame 7 connected to the rotating shaft 41 can be multiple horizontal connecting rods, such as three connecting rods (upper, middle, and lower) along the axial direction of the rotating shaft 41. The ends of the three connecting rods close to the inner wall of the tank 1 are all fixed to the vertically set fixing rod for adhering the scraper, thereby making the scraper more securely fixed and not generating excessive resistance when rotating, nor hindering the sedimentation of the internal fruit pomace.
[0043] With the above settings, if the pomace floats to the surface, some of the pomace will adhere to the inner wall of the tank 1. As the spiral blade 42 rotates, it can be scraped off by the scraper and then allowed to settle. This also facilitates cleaning of the tank 1 after brewing and prevents too much pomace from adhering to the inner wall of the tank 1.
[0044] A filter screen is detachably connected inside the tank body 1. It can be connected by snapping on the edge of the filter screen. For example, the filter screen has buckles on the edge. To remove it, press the buckle protrusions on both sides. A liquid outlet pipe 8 is set at the bottom of the tank body 1. The liquid outlet pipe 8 is equipped with a valve for control. It can be opened when liquid needs to be discharged. The filter screen is fixed to the inner wall of the tank body 1 and located above the liquid outlet pipe 8. When the wine is brewed and discharged, the filter screen can filter out the fruit pomace, making the wine clearer.
[0045] Implementation
[0046] The crushed fruit pulp or pomace is poured into tank 1, followed by the wine. Fermentation begins. After a period of fermentation, the gas pressure pushes the pressure plate 21, triggering the self-resetting button switch. The motor 53 then starts working. When the gas level inside the tank reaches the specified threshold, the hydraulic check valve 3 opens to release the internal air pressure. Simultaneously, the water storage box 63 is periodically squeezed to allow the pH test paper to absorb the released gas. The presence of carbon dioxide is observed. If carbon dioxide is present, the gear on the top of the lid 2 or the motor 53 is checked for operation. If not, the motor 53 is manually operated via an external switch, and the pH test paper is replaced for future use. After fermentation is complete, the liquid is discharged by opening the valve on the outlet pipe 8.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
