Description

Technical Field

[0001] The utility model relates to the technical field of wine brewing, and more particularly, to a wine fermentation tank. Background Art

[0002] Wine is a fermented wine with a certain alcohol content, which is brewed from grapes or grape juice through all or part of alcoholic fermentation.

[0003] Since grape skins contain important components such as tannins, pigments, and aromatic substances, when brewing red wine, grape juice and grape skins are put into a container together, and maceration and fermentation are carried out simultaneously to extract tannins, pigments, and aromatic substances from the grape skins, so as to make the wine have a better flavor. During the fermentation process, a large amount of carbon dioxide gas and heat are generated. The carbon dioxide gas will push the grape skins to the top of the liquid surface, forming a "cap", which causes the grape skins and grape juice to not fully contact, affecting the maceration effect. In addition, the formed "cap" will affect the dissipation of heat, resulting in too high a fermentation temperature, thus affecting the quality of the finished product; in the existing fermentation equipment during the fermentation process, it is usually necessary to frequently open the lid manually to press the cap formed inside to below the liquid surface, and continuous "cap pressing" is carried out to ensure full contact between the grape skins and grape juice. This method has low efficiency due to the need to frequently open the tank for cap pressing operations, and frequent opening of the tank may also affect the normal progress of the fermentation work. In addition, since fermentation is usually carried out in a closed container, a large amount of gas and heat generated during the fermentation process will increase the air pressure inside the container, resulting in the risk of being injured by air pressure impact when opening the lid manually, and if the fermentation equipment cannot be depressurized in time during the fermentation process, there is even a risk of explosion. Therefore, there are certain safety hazards in the existing fermentation equipment. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a wine fermentation tank that is convenient for cap pressing work and has high safety.

[0005] The purpose of this application is achieved through the following technical solutions:

[0006] A wine fermentation tank, comprising a tank body, a pressure relief component and a pressing cap mechanism. The tank body is provided with a feed inlet and a discharge outlet. A pressure relief groove for installing the pressure relief component is arranged at the top of the tank body. An air outlet hole is opened at the bottom of the pressure relief groove. The pressure relief component comprises an end cover, an elastic member, a push block and a sealing ring which are arranged in sequence from top to bottom. A first pressure relief hole is opened on the end cover. The sealing ring is located at the bottom of the pressure relief groove and surrounds the air outlet hole. The bottom of the push block abuts against the sealing ring. Two ends of the elastic member respectively abut against the push block and the end cover. The pressing cap mechanism comprises a pressing cap driving member and a pressing plate connected to the output end of the pressing cap driving member. The pressing plate is located inside the tank body, and a plurality of filter holes are evenly distributed on the pressing plate.

[0007] In the above technical solution, before fermentation, raw materials enter the inner cavity of the tank body through the feed inlet, and the finished product after fermentation is discharged through the discharge outlet at the bottom of the tank body. When red wine is fermented, a wine cap will be formed at the top of the liquid level in the tank body. By driving the pressing plate to press down through the pressing cap driving member, the wine cap at the top can be pressed into the liquid level, so that the grape skins and grape juice are in full contact, in order to extract more tannins, pigments and aromas. Among them, a plurality of filter holes are provided on the pressing plate, through which grape juice can pass, thereby reducing the resistance during the movement of the pressing plate, avoiding excessive agitation of the internal wine liquid, and ensuring the normal progress of fermentation; the pressure relief groove at the top of the tank body is provided with an air outlet hole, and the air outlet hole connects the pressure relief groove with the inner cavity of the tank body. In the initial state, the elastic member is in a compressed state. Under the elastic force of the elastic member, the push block presses the sealing ring tightly on the outer peripheral side of the air outlet hole, thereby sealing the air outlet hole. During the fermentation process, when the gas generated inside the tank body reaches the critical value, the push block will be pushed up through the air outlet hole. At this time, the elastic member is compressed, and there is insufficient sealing amount between the push block and the sealing ring to generate a gap, so that a part of the gas leaks out from this gap and is discharged to the outside of the tank body through the first pressure relief hole at the top of the end cover. After the air pressure inside the tank body returns to normal, the elastic member rebounds, and the push block continues to press the sealing ring tightly to seal the air outlet hole. By setting the pressure relief component, the air pressure inside the tank body can be automatically adjusted to keep the air pressure inside the tank body in a stable state all the time, avoiding the possibility of staff being injured or explosion caused by too high air pressure, and effectively improving safety.

[0008] Further, a protruding limiting ring is arranged on the peripheral side of the push block. The elastic member is sleeved on the push block, and two ends of the elastic member respectively abut against the end face of the limiting ring and the bottom of the end cover.

[0009] In the above technical solution, the elastic member is sleeved on the push block, the top end of the elastic member is higher than the top of the push block, and abuts against the bottom of the end cover.

[0010] Further, the outer diameter of the limiting ring is matched with the width of the pressure relief groove, and a plurality of second pressure relief holes are opened on the limiting ring.

[0011] In the above technical solution, the outer diameter of the limit ring matches the width of the pressure relief groove to prevent the push block from deflecting during movement. The limit ring is provided with a second pressure relief hole for the leaked gas to pass through.

[0012] Further, an installation groove is provided at the top of the tank body, and the installation groove is distributed around the outside of the pressure relief groove. The end cover is installed in the installation groove and covers the opening of the pressure relief groove.

[0013] In the above technical solution, the end cover is fixedly installed on the top of the tank body through the installation groove. After installation, the end cover covers the opening of the pressure relief groove, so that the top of the elastic member abuts against the bottom surface of the end cover.

[0014] Further, a sealing groove for installing the sealing ring is formed at the bottom of the pressure relief groove, and the sealing groove surrounds the air outlet hole.

[0015] In the above technical solution, the sealing ring is fixedly installed in the sealing groove to prevent the sealing ring from being lifted when the push block moves, avoiding subsequent sealing failure.

[0016] Further, a protruding portion is provided at the edge position of the bottom surface of the pressing plate.

[0017] In the above technical solution, the protruding portion helps to gather the grape skins so that all of them are pressed below the liquid level by the pressing plate, avoiding the grape skins being stuck in the gap between the pressing plate and the side wall of the tank body.

[0018] Further, a filter screen and a control valve are installed at the discharge port. The filter screen is arranged at the top of the discharge port, and the control valve is used to control the opening and closing of the discharge port.

[0019] In the above technical solution, the filter screen can prevent the grape skins from passing through. After fermentation is completed, the control valve is opened, and the fermented wine liquid is discharged from the discharge port for subsequent bottling and other operations. The grape skins remain inside the tank body under the action of the filter screen and wait for subsequent cleaning.

[0020] Further, a switchable discharge door is provided on one side of the bottom of the tank body.

[0021] In the above technical solution, the discharge door is rotatably installed on the side wall of the tank body. After all the fermented wine liquid is discharged, the discharge door can be opened to clean the grape skin residue inside.

[0022] Further, a feeding mechanism is provided on one side of the tank body away from the discharge door. The feeding mechanism includes a top-pushing driving member arranged outside the tank body and a push plate connected to the output end of the top-pushing driving member. The top-pushing driving member drives the push plate to approach and move away from the discharge door.

[0023] In the above technical solution, after the wine liquid is discharged, the pushing drive member can drive the push plate to push the grape skin dregs at the bottom of the tank out from the discharge door. Compared with manual operation, the cleaning efficiency can be effectively improved.

[0024] Furthermore, a temperature regulating pipe is provided inside the tank. The inlet end and the outlet end of the temperature regulating pipe are both installed on the side wall of the tank, and a temperature sensor for detecting the internal temperature of the tank is provided outside the tank.

[0025] In the above technical solution, by introducing a heat-conducting fluid into the temperature regulating pipe, the temperature of the internal wine liquid can be adjusted during the fermentation process to ensure the normal progress of fermentation. The temperature sensor can detect the temperature of the wine liquid inside the tank to facilitate timely detection of whether the temperature is abnormal.

[0026] Compared with the prior art, the beneficial effects of the present application are as follows:

[0027] Through the provided cap pressing mechanism, the present application can automatically press the wine cap formed on the top of the liquid surface under the liquid surface, so that the grape skins are fully in contact with the grape juice, ensuring the effect of skin maceration to extract more tannins, pigments and aromas, improving the quality of the finished wine, and without the need for manual opening of the fermentation tank multiple times for cap pressing, which is more convenient to use and has higher efficiency; through the provided pressure relief component, the present application can automatically adjust the air pressure inside the tank to keep the air pressure inside the tank in a stable state all the time, avoiding the risk of injury to workers caused by too high air pressure inside the tank or explosion, and effectively improving safety.

Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Generally, the components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0035] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0036] Please refer to Figures 1 to 2 , this embodiment provides a wine fermentation tank, which includes a tank body 1, a pressure relief component 2, and a cap pressing mechanism 3. The tank body 1 is provided with a feed inlet 11 and a discharge outlet 12. A pressure relief groove 13 for installing the pressure relief component 2 is provided at the top of the tank body 1. An air vent hole 131 is opened at the bottom of the pressure relief groove 13. The pressure relief component 2 includes an end cover 21, an elastic member 22, a pusher block 23, and a sealing ring 24 arranged in sequence from top to bottom. A plurality of first pressure relief holes 211 are opened on the end cover 21. The sealing ring 24 is located at the bottom of the pressure relief groove 13 and surrounds the air vent hole 131. The bottom of the pusher block 23 abuts against the sealing ring 24. The two ends of the elastic member 22 respectively abut against the pusher block 23 and the end cover 21. The cap pressing mechanism 3 includes a cap pressing driving member 31 and a pressing plate 32 connected to the output end of the cap pressing driving member 31. The cap pressing driving member 31 is located at the top of the tank body 1. The pressing plate 32 is located inside the tank body 1. A plurality of filter holes are evenly distributed on the pressing plate 32.

[0037] In this embodiment, before fermentation, the raw materials enter the inner cavity of the tank body 1 through the feed port 11, and the finished products after fermentation are discharged through the discharge port 12 at the bottom of the tank body 1. When fermenting red wine, a wine cap will be formed at the top of the liquid level in the tank body 1. By driving the pressing plate 32 to press down through the wine cap driving member 31, the wine cap at the top can be pressed into the liquid level, so that the grape skins and grape juice are in full contact, in order to extract more tannins, pigments and aromas. Among them, a plurality of filter holes are provided on the pressing plate 32 for the grape juice to pass through, thereby reducing the resistance of the pressing plate 32 during movement and avoiding excessive agitation of the internal wine liquid to ensure the normal progress of fermentation; the pressure relief groove 13 at the top of the tank body 1 is provided with an air outlet 131, and the air outlet 131 communicates the pressure relief groove 13 with the inner cavity of the tank body 1. In the initial state, the elastic member 22 is in a compressed state. Under the elastic force of the elastic member 22, the push block 23 presses the sealing ring 24 tightly on the outer peripheral side of the air outlet 131, thereby sealing the air outlet 131. During the fermentation process, when the gas generated inside the tank body 1 during fermentation reaches the critical value, the push block 23 will be pushed up through the air outlet 131. At this time, the elastic member 22 is compressed, and the sealing amount between the push block 23 and the sealing ring 24 is insufficient to generate a gap, so that a part of the gas leaks out from this gap and is discharged to the outside of the tank body 1 through the first pressure relief hole 211 at the top of the end cover 21. After the air pressure inside the tank body 1 returns to normal, the elastic member 22 rebounds, and the push block 23 continues to press the sealing ring 24 tightly to seal the air outlet 131. By setting the pressure relief assembly 2, the air pressure inside the tank body 1 can be automatically adjusted to keep the air pressure inside the tank body 1 in a stable state all the time, avoiding the possibility of staff being injured or explosion caused by too high air pressure, and effectively improving safety.

[0038] Specifically, the elastic member 22 in this embodiment is selected as a spring. In addition to the spring, other elastic parts that meet the conditions can also be selected.

[0039] It should be noted that most red wine fermentations require the addition of grape skins for maceration. The grape skins are pushed to the liquid level by the gas generated during fermentation, so a wine cap will be generated and the wine cap pressing work needs to be carried out by starting the wine cap pressing mechanism 3. While the white wine fermentation process only uses grape juice for fermentation, so no wine cap will be generated and no wine cap pressing work is required. This fermentation tank can be used for the fermentation of red wine or white wine.

[0040] Please refer to Figure 2 , in this embodiment, a protruding limiting ring 231 is provided on the periphery of the push block 23. The elastic member 22 is sleeved on the push block 23, and the top end of the elastic member 22 is higher than the top of the push block 23 by a certain distance, so that the two ends of the elastic member 22 are respectively abutted against the end face of the limiting ring 231 and the bottom of the end cover 21. Among them, a spacing is reserved between the push block 23 and the end cover 21 for the push block 23 to be pushed up to ensure the normal progress of the pressure relief work.

[0041] Please refer toFigure 2 , in this embodiment, the outer diameter of the limiting ring 231 matches the width of the pressure relief groove 13 to prevent the push block 23 from deflecting during movement. A plurality of second pressure relief holes 2311 are provided on the limiting ring 231 for the leaked gas to pass through. The second pressure relief holes are distributed at the outer side of the sealing ring 24.

[0042] Please refer to Figure 2 , in this embodiment, an installation groove 14 is provided at the top of the tank body 1. The installation groove 14 is distributed around the outer side of the pressure relief groove 13. The end cover 21 is fixedly installed on the top of the tank body 1 through the installation groove 14. After installation, the end cover 21 covers the opening of the pressure relief groove 13, so that the top of the elastic member 22 abuts against the bottom surface of the end cover 21.

[0043] Specifically, the installation groove 14 can be connected to the installation groove 14 by means of spinning, welding, etc. As long as it is ensured that the end cover 21 is fixed in the vertical direction after installation to ensure the limiting effect on the elastic member 22.

[0044] Please refer to Figure 2 , in this embodiment, a sealing groove 14 for installing the sealing ring 24 is opened at the bottom of the pressure relief groove 13. The sealing groove 14 surrounds the air outlet hole 131. The sealing ring 24 is fixedly installed in the sealing groove 14. Thus, when the push block 23 moves, it can prevent the sealing ring 24 from adhering to the bottom of the push block 23 and being lifted by the push block 23, avoiding the subsequent failure of the sealing effect.

[0045] Please refer to Figure 1 , in this embodiment, a protruding portion 321 is provided at the edge position of the bottom surface of the pressing plate 32. The protruding portion 321 helps to gather the grape skins and prevent the grape skins from moving outward and getting stuck in the gap between the pressing plate 32 and the side wall of the tank body 1 when the grape skins are pressed below the liquid level.

[0046] Please refer to Figure 1 , in this embodiment, a filter screen 121 and a control valve 122 are installed at the discharge port 12. The filter screen 121 is arranged at the top of the discharge port 12 and can block the passage of grape skins. The control valve 122 is used to control the opening and closing of the discharge port 12. When the fermentation is completed, the control valve 122 is opened, and the fermented wine liquid is discharged from the discharge port 12 for subsequent bottling and other operations. The grape skins remain inside the tank body 1 under the action of the filter screen 121 and wait for subsequent cleaning.

[0047] Specifically, in this embodiment, the control valve 122 is selected as an electromagnetic valve and can be controlled by a computer program to achieve more precise control.

[0048] Please refer to Figure 1, in this embodiment, an openable discharge door 15 is provided on one side of the bottom of the tank body 1. The top side of the discharge door 15 is rotatably installed on the side wall of the tank body 1. A handle is provided on the outer side of the discharge door 15 to facilitate the opening and closing of the discharge door 15. After all the fermented wine liquid is discharged, the discharge door 15 can be opened to clean the grape skin residue at the bottom inside the tank body 1.

[0049] Please refer to Figure 1 , in this embodiment, a feeding mechanism 4 is provided on the side of the tank body 1 away from the discharge door 15. The feeding mechanism 4 includes a top-pushing driving member 41 provided outside the tank body 1 and a push plate 42 connected to the output end of the top-pushing driving member 41. The push plate 42 is of an "L" shape, and the bottom of the push plate 42 is close to the bottom inside the tank body 1. The top-pushing driving member 41 drives the push plate 42 to approach and move away from the discharge door 15. After the wine liquid inside the tank body 1 is discharged, the top-pushing driving member 41 can drive the push plate 42 to push the grape skin residue at the bottom of the tank body 1 out from the discharge door 15, and the grape skin residue is cleaned through the feeding mechanism 4. Compared with manual operation, the cleaning efficiency can be effectively improved and time can be saved.

[0050] Please refer to Figure 1 , in this embodiment, a temperature regulating pipe 5 is provided inside the tank body 1. The inlet end and the outlet end of the temperature regulating pipe 5 are both installed on the side wall of the tank body 1. By introducing a heat-conducting fluid into the temperature regulating pipe 5, the temperature of the wine liquid inside can be adjusted during the fermentation process to ensure the normal progress of fermentation. A temperature sensor 6 for detecting the internal temperature of the tank body 1 is provided outside the tank body 1. The temperature sensor 6 can detect the temperature of the wine liquid inside the tank body 1 to facilitate timely detection of whether the temperature is abnormal.

[0051] Specifically, the temperature regulating pipe 5 in this embodiment is a disc-shaped copper pipe. Copper has excellent heat-conducting performance, and the coiled pipe structure can effectively increase the contact area with the liquid, resulting in better heat-conducting effect.
