Description

Technical Field

[0001] The present invention relates to the technical field of wine fermentation, and particularly to a wine fermentation device with a detection function. Background Art

[0002] A wine fermentation tank is a container specifically designed for the wine fermentation process. During the wine brewing process, fermentation is a crucial step. During wine fermentation, the "pomace" composed of grape skins, seeds, and stems naturally floats on the wine due to its lower density, forming a "cap". When a cap plate is used to try to press this layer of pomace into the wine, the bottom layer of the pomace is often tightly compressed due to the buoyancy of the wine, hindering the effective penetration of the wine into the pomace. This situation limits the full contact between the wine and the pigments, flavor substances, tannins, and other components rich in the pomace, thereby weakening the extraction effect of these important components.

[0003] Furthermore, when separating the wine in the fermentation tank from the pomace subsequently, the pomace accumulates and forms a blockage at the filter device or the drainage pipe outlet, hindering the smooth outflow of the wine, resulting in a significant reduction in the wine drainage speed, and requiring frequent cleaning of the filter or the pipe, reducing the wine drainage efficiency.

[0022] The pump spraying assembly includes a pump 201, a liquid suction pipe 202, a liquid discharge pipe 203 and a three-way valve 204; the pump 201 is fixedly connected to the fermentation tank 1; the liquid suction pipe 202 is fixedly connected to the pump 201; the liquid suction pipe 202 communicates with the lower part of the fermentation tank 1; the liquid discharge pipe 203 is fixedly connected to the pump 201; the upper part of the liquid discharge pipe 203 is fixedly connected to the can lid 2; a telescopic part 20301 is arranged on the liquid discharge pipe 203; the three-way valve 204 is fixedly connected to the liquid discharge pipe 203.

[0023] The pump spraying assembly further includes a liquid outlet cover 205; the liquid outlet cover 205 is fixedly connected to the liquid discharge pipe 203; the liquid outlet cover 205 is located above the pressure cap plate 5; the liquid outlet cover 205 is arranged in an inclined shape that fits the upper side of the pressure cap plate 5.

[0024] The plugging assembly includes an annular slide rail 301, an electric slider 302 and a plugging plate 303; the annular slide rail 301 is fixedly connected inside the fermentation tank 1; two symmetrically arranged electric sliders 302 are slidably connected to the annular slide rail 301; a plugging plate 303 is fixedly connected to all the electric sliders 302 together; the plugging plate 303 is arranged in a curved arc shape; a storage groove 1003 is opened on the fermentation tank 1; the discharge groove 1002 communicates with the storage groove 1003.

[0025] An upward protrusion 6001 is arranged below each stirring roller 6; a plurality of notches 7002 that fit with the protrusions 6001 are opened on the lower side of the filter plate 7.

[0026] The bottom of the discharge groove 1002 is arranged in an inclined shape that gradually decreases towards the center of the fermentation tank 1, which is beneficial to preventing pulp from remaining in the discharge groove 1002.

[0027] It further includes a support assembly, and the support assembly includes a third telescopic driving member 401 and a support block 402; a plurality of third telescopic driving members 401 arranged in a circular array are fixedly connected to the fermentation tank 1, and the third telescopic driving member 401 is an electric push rod; a plurality of cavities 1004 arranged in a circular array are opened inside the fermentation tank 1; a support block 402 is slidably connected to each cavity 1004; the telescopic end of each third telescopic driving member 401 is fixedly connected to a support block 402.

[0028] When fermenting wine, control the telescopic driving member 1 to drive the tank lid 2 to rise, so that the tank lid 2 drives the pressing cap plate 5 to rise through the telescopic driving member 2 101 until the pressing cap plate 5 disengages from the fermentation tank 1. Subsequently, the crushed grape pulp mixed with yeast is transported into the fermentation tank 1 through an external feeding device, causing the pulp to accumulate on the upper side of the filter plate 7. After the transportation of the pulp and juice is completed, control the telescopic driving member 1 to drive the tank lid 2 to descend and cover the upper side of the fermentation tank 1, so that the tank lid 2 drives the pressing cap plate 5 into the fermentation tank 1. Since the pulp has a lower specific gravity, when the pulp ferments in the fermentation tank 1, it will float on the surface of the juice, forming a layer of wine cap. It should be noted that after the pulp floats to the surface of the juice, its height is lower than the discharge groove 1002. At this time, control the telescopic driving member 2 101 to drive the sealing cover 102 and the motor 103 inside it to descend, so that the motor 103 drives the pressing cap plate 5 and the stirring roller 6 to descend together. The floating pulp is pressed into the juice through the pressing cap plate 5. During this process, the juice surges through the filter holes on the pressing cap plate 5 to the upper side of the pressing cap plate 5, enabling the pigments and aromatic substances in the pulp to come into full contact with the juice, which is conducive to accelerating the dissolution of the active ingredients. When the pressing cap plate 5 presses the floating pulp into the juice, control the motor 103 to drive the pressing cap plate 5 and the stirring roller 6 to rotate, so that the stirring roller 6 fully stirs and mixes the pulp pressed into the juice, preventing the pulp from being pressed into the juice by the pressing cap plate 5 and then accumulating tightly under the influence of buoyancy, avoiding the juice from being unable to enter the inside of the pulp for full contact, and improving the extraction effect of the juice on the internal components of the pulp. When the juice ferments in the fermentation tank 1, the carbon dioxide sensor 4 is used to detect the carbon dioxide content in the fermentation tank 1 in real time, and the residual sugar content can be estimated, and the operation nodes such as cap pressing and cooling can be planned in advance, which can significantly improve the controllability of the fermentation process and the quality of the wine.

[0029] When the pressing cap plate 5 presses the cap of the pulp, control the pump 201 to suck the juice and yeast mud at the bottom of the fermentation tank 1 through the liquid suction pipe 202, and pump and discharge it from the upper part of the fermentation tank 1 through the liquid discharge pipe 203, so that the juice and yeast mud at the bottom of the fermentation tank 1 come into contact with the pulp and juice at the upper part of the fermentation tank 1, which is conducive to accelerating the dissolution of pigments and aromatic substances in the pulp and improving the fermentation effect of the juice. During the pumping and spraying process, the pressing cap plate 5 drives the stirring roller 6 to fully stir and mix the juice, pulp and yeast mud, preventing the yeast mud from accumulating tightly due to the influence of the buoyancy of the pulp and avoiding the yeast mud from being unable to deposit normally downward, enhancing the mixing effect of the juice, pulp and yeast mud, and thus enhancing the fermentation effect of the juice.

[0030] When the pressing cap plate 5 presses the pulp, some smaller pulp is likely to surge upwards from the filter holes on the pressing cap plate 5 along with the juice to the upper side of the pressing cap plate 5. After the pressing cap plate 5 completes one pressing operation, control the second telescopic driving member 101 to drive the sealing cover 102 and the motor 103 to rise, so that the motor 103 drives the pressing cap plate 5 to rise from the juice. When the pressing cap plate 5 rises, it drives the pulp that has surged to the upper side of the pressing cap plate 5 to rise together. When the edge of the pressing cap plate 5 rises to the position of the discharge groove 1002, control the motor 103 to drive the pressing cap plate 5 to rotate. While ensuring the mixing effect of the juice, pulp and yeast mud, the pulp on the upper side of the pressing cap plate 5 moves towards the edge of the pressing cap plate 5 under the action of centrifugal force and is flung from the edge of the pressing cap plate 5 into the discharge groove 1002. At the same time, the juice pumped out from the drain pipe 203 flushes the upper side of the pressing cap plate 5, so that the juice flows towards the edge of the pressing cap plate 5 under the action of centrifugal force and is flushed into the discharge groove 1002, flushing the pulp remaining on the pressing cap plate 5 from the discharge groove 1002 into the pulp floating under the pressing cap plate 5, preventing the pulp from remaining on the upper side of the pressing cap plate 5 and not being able to contact the juice, avoiding the oxidation reaction of the pulp, and further avoiding the contamination of the wine in the fermentation tank 1 by the oxidized pulp, ensuring the quality of the brewed wine. At the same time, since the pressing cap plate 5 is set in a frustum shape, when the pressing cap plate 5 rises and rotates, it is beneficial to enhance the cleaning effect of the remaining pulp on its upper side.

[0031] It is also considered that when the pressing cap plate 5 presses the pulp, some pulp is likely to get stuck in the filter holes on the pressing cap plate 5 along with the surging of the juice, resulting in a decrease in the permeability of the pressing cap plate 5. At the same time, the pulp remaining in the filter holes is prone to oxidation and deterioration, affecting the quality of the fermented wine. Therefore, after the pressing cap plate 5 rises and rotates and the juice pumped out from the drain pipe 203 finishes cleaning the upper side of the pressing cap plate 5, control the second telescopic driving member 101 to drive the pressing cap plate 5 to continue to rise, so that the upper side of the pressing cap plate 5 fits with the liquid outlet cover 205. It should be noted that the pressure of the juice pumped by the pump 201 into the drain pipe 203 is relatively large. After the juice pumped out from the drain pipe 203 enters the liquid outlet cover 205, the juice in the liquid outlet cover 205 can only be discharged from the filter holes on the pressing cap plate 5. Therefore, the pressure in the liquid outlet cover 205 is also relatively large. When the filter holes blocked by the pulp rotate to the lower side of the liquid outlet cover 205 along with the pressing cap plate 5, the pulp stuck in the filter holes is flushed downward by the pressure of the juice inside the liquid outlet cover 205, realizing the cleaning work of each filter hole on the pressing cap plate 5, preventing the pulp from remaining in the filter holes and undergoing oxidation and deterioration, and avoiding affecting the quality of the fermented wine.

[0032] As the grape juice continues to ferment in the fermentation tank 1, the grape juice gradually turns into wine. After the fermentation work is completed, it is necessary to separate the wine in the fermentation tank 1 from the pomace produced after the fermentation of the pulp. First, open the three-way valve 204 to block the connection between the pump 201 and the drain pipe 203, and control the pump 201 to discharge the wine in the fermentation tank 1 to the external container through the three-way valve 204 by the suction pipe 202. During this process, the filter plate 7 blocks the pomace in the fermentation tank 1 to prevent the pomace from blocking the suction pipe 202, ensuring smooth drainage and improving the drainage efficiency. During the drainage process, control the motor 103 to drive the pressure cap plate 5 and the stirring roller 6 to rotate, so that the stirring roller 6 is aligned with the through groove 7001. Then, control the telescopic driving member two 101 to drive the pressure cap plate 5 and the stirring roller 6 to descend, so that the stirring roller 6 passes through the through groove 7001. Taking the top-down view as the reference, control the motor 103 to drive the pressure cap plate 5 and the stirring roller 6 to rotate clockwise, so that the lower part of the L-shaped stirring roller 6 hooks the lower side of the filter plate 7, and the protrusion 6001 is inserted into the notch 7002. Then, control the telescopic driving member two 101 to drive the pressure cap plate 5 and the stirring roller 6 to rise, so that the stirring roller 6 drives the filter plate 7 to rise together. At this time, the pomace inside the fermentation tank 1 is located between the pressure cap plate 5 and the filter plate 7. When the telescopic driving member two 101 drives the pressure cap plate 5 and the filter plate 7 to rise, control the electric slider 302 to drive the sealing plate 303 to slide on the annular slide rail 301, so that the sealing plate 303 moves from the storage groove 1003 to the discharge groove 1002 to block the discharge groove 1002, preventing the pomace from getting stuck in the discharge groove 1002 when the subsequent pressure cap plate 5 and the filter plate 7 rise through the discharge groove 1002, ensuring the cleaning effect of the pomace.

[0033] After the telescopic end of the second telescopic driving member 101 is completely retracted, control the first telescopic driving member 3 to drive the tank cover 2 to start rising, so that the tank cover 2 drives the second telescopic driving member 101 to rise, and then the second telescopic driving member 101 drives the pressing cap plate 5 and the filter plate 7 to continue rising. During the rising process of the tank cover 2, the upper part of the liquid discharge pipe 203 is driven by the tank cover 2 to rise together, and the telescopic part 20301 is stretched. When the filter plate 7 rises above the support block 402, control the third telescopic driving member 401 to drive the support block 402 to extend out of the cavity 1004. Subsequently, control the second telescopic driving member 101 to drive the pressing cap plate 5 and the filter plate 7 to descend, so that the filter plate 7 is supported by the support block 402. Then control the second telescopic driving member 101 to drive the pressing cap plate 5 and the stirring roller 6 to continue descending, so that the pressing cap plate 5 approaches the filter plate 7. At this time, the liquid level of the wine in the fermentation tank 1 is lower than the filter plate 7. The pomace is squeezed on the filter plate 7 through the pressing cap plate 5, and a large amount of residual wine liquid in the pomace is squeezed out, so that the wine liquid flows from the filter holes on the filter plate 7 into the wine in the fermentation tank 1, improving the extraction effect of the wine, preventing wine waste, and at the same time accelerating the separation efficiency of the wine and the pomace. When the pressing cap plate 5 and the filter plate 7 lift the squeezed pomace out of the fermentation tank 1, the pomace is received and collected by an externally provided pomace receiving container. Since the filter plate 7 is arranged in a frustum shape, it is convenient for the pomace to separate from the filter plate 7. When the wine liquid in the fermentation tank 1 is discharged, open the sludge discharge port 1001 to discharge the dead yeast mud accumulated at the bottom of the fermentation tank 1, and complete the separation work of the wine and the pomace.

[0034] Embodiment 2

[0035] On the basis of Embodiment 1, as Figures 1-3 and Figure 6 shown, it further includes a collection system. The collection system includes a collection frame 501 and a liquid outlet pipe 502; the upper part of the outer side of the fermentation tank 1 is fixedly connected with the collection frame 501; the inner wall of the collection frame 501 is coated with an anti-adhesion coating; the bottom of the collection frame 501 is arranged in an inclined shape; the bottom of the collection frame 501 is fixedly connected with the liquid outlet pipe 502; the liquid outlet pipe 502 is located at the lowest point of the inclined bottom of the collection frame 501.

[0036] A number of isolation covers 50101 are arranged on the collection frame 501; the surfaces of the isolation covers 50101 are coated with an anti-adhesion coating.

[0037] When the pressing cap plate 5 and the filter plate 7 lift the squeezed pomace out of the fermentation tank 1, the pomace is received and collected by the collection frame 501, so that the residual wine in the pomace flows along the inclined bottom of the collection frame 501 to the liquid outlet pipe 502, and then flows from the liquid outlet pipe 502 into an externally provided collection container, further enhancing the extraction effect of the wine and reducing wine waste. When the pomace enters the collection frame 501, the outer side of the fixed end of the first telescopic driving member 3 is covered by the isolation cover 50101 to prevent the pomace from adhering to the first telescopic driving member 3, facilitating subsequent cleaning of the pomace.
