Description

Technical Field

[0001] The invention relates to the technical field of fruit wine production equipment, in particular to a fruit wine fermentation device with the functions of enhancing aroma and color. Background Art

[0002] The principle of fruit wine fermentation is mainly based on the alcohol fermentation of yeast. During the fermentation process of fruit wine, raw materials such as grape skins produce carbon dioxide gas during fermentation. These gases cause the skin residue to float and gather on the surface of the liquid, forming a layer of bubbles. This phenomenon prevents the tannins, pigments and other phenolic substances in the peel from fully contacting with the fermentation liquid, making it difficult for these beneficial ingredients to be effectively leached. In order to fully extract the pigments and functional substances in the skin residue, corresponding measures need to be taken to ensure that these ingredients can fully contact with the fermentation liquid.

[0003] To this end, the Chinese patent with the authorization announcement number CN218969181U discloses a fruit wine fermentation device with the function of online flavor enhancement and color enhancement, which can not only realize the enhancement or optimization of the color, fruit aroma and flavor of the fruit wine by extracting the exogenous substances in the extraction tank, but also can realize the "capping" of the mash in the fermentation tank by the reflux of the extracting liquid, thereby increasing the dissolution of its color, aroma and flavor. The brewing tank can realize a separate "capping" operation by bypassing the circulation, that is, through the spraying of the first spraying device, the peel floating in the brewing tank is again contacted with the fermentation liquid in the fermentation tank to realize the extraction of pigments and flavor substances, and the "capping" operation during the main fermentation period can be realized without extracting exogenous pigments and aroma substances.

[0004] However, the capping operation by spraying or pipe spraying requires precise control of parameters such as liquid flow, pressure and spraying time, otherwise the consistency and stability of the capping effect cannot be ensured. In addition, too many pipes, valves and other equipment may leak or be incompletely cleaned, which may introduce pollutants and affect the quality and safety of the fruit wine. Summary of the invention

[0005] In view of the above problems, a fruit wine fermentation device with aroma and color enhancement function is provided, which solves the problem that the consistency and stability of the capping effect cannot be controlled by spraying capping through a fermentation tank, a built-in pump and a material feeding mechanism.

[0006] In order to solve the problems of the prior art, the present invention provides a fruit wine fermentation device with the function of enhancing aroma and color, including a fermentation tank, a built-in pump is arranged in the fermentation tank, the built-in pump includes a top cover, a first rotating shaft is rotatably arranged on the top cover, a paddle is sleeved on the first rotating shaft, a rotating drive component for driving the first rotating shaft is provided on the fermentation tank, a material shifting mechanism for shifting scum is provided on the top cover, and a transmission mechanism is also provided on the top cover, and the material shifting mechanism is transmission-connected to the first rotating shaft through the transmission mechanism.

[0007] Preferably, the charging mechanism includes at least two charging components. Each charging component includes a pulley and a transmission belt. There are two pulleys which are rotatably arranged on the top cover. The pulley is drivingly connected to the first rotating shaft through a transmission mechanism. The transmission belt connects the two pulleys. Through holes for the fermentation liquid to pass through are formed in the transmission belt, and bristles are arranged on the transmission belt.

[0008] Preferably, the transmission mechanism includes a first transmission component and a synchronous transmission component. The first rotating shaft is drivingly connected to the synchronous transmission component through the first transmission component. The pulleys of multiple charging components are drivingly connected through the synchronous transmission component.

A second transmission component is provided on the top cover. The mounting shaft is drivingly connected to the first rotating shaft through the second transmission component, and through holes for the fermentation liquid to pass through are formed in the top cover.

[0010] Preferably, a mounting strip is provided on the top cover, and comb teeth are arranged on the mounting strip. When the transmission belt rotates, the comb teeth rub against the bristles.

[0011] Preferably, a cover is provided on the top cover to shield the transmission mechanism.

[0012] Preferably, there are at least three built-in pumps, and multiple built-in pumps are arranged in a circular array about the axis of the fermentation tank.

[0013] Preferably, a support frame is arranged in the fermentation tank, and the built-in pump is arranged on the support frame. A bottom sieve for filtering scum is provided at the bottom of the built-in pump.

[0014] Preferably, a linear drive component for controlling the lifting of the support frame is provided on the fermentation tank.

[0015] Preferably, a liquid level sensor for detecting the water level is provided on the top cover.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: 1. The present invention realizes the function of controlling the floating dregs to flow with the liquid through the fermentation tank, the built-in pump and the charging mechanism, thereby achieving the cap pressing effect. At the same time, the charging action of the charging mechanism can prevent the floating dregs from contacting and being broken by the impeller of the built-in pump, thereby avoiding the cell structure in the peel from being broken and affecting the taste and aroma of the fruit wine. While ensuring the quality of the fruit wine, the problem that the consistency and stability of the cap pressing effect cannot be controlled by spraying is solved. Compared with the traditional cap pressing operation, the method of cap pressing through the liquid flow can increase the dissolution of color and flavor in the pomace, and improve the flexibility and controllability of the fermentation process. At the same time, when the floating dregs flow with the liquid and reach above the built-in pump, the floating dregs are deflected to the side of the built-in pump by the charging mechanism on the top cover, thereby preventing the floating dregs from contacting and being broken by the impeller and stabilizing the fermentation quality of the fruit wine.

[0017] 2. The present invention realizes the function of skimming scum through a pulley and a transmission belt. And through the control of the transmission mechanism, while the first rotating shaft drives the paddle to rotate, it also drives the pulley to rotate. The pulley drives the transmission belt to rotate, and then the bristles attached to the transmission belt deflect the scum flowing towards the paddle along with the fermentation broth to both sides of the top cover, preventing the scum from contacting the rotating paddle and being broken, and stabilizing the fermentation quality of the fruit wine.

[0018] 3. The present invention realizes the function of synchronously rotating the pulleys of multiple feeding components through the first transmission component and the synchronous transmission component, and further realizes the effect of synchronously controlling the operation of multiple feeding components when the rotation driving component drives the first rotating shaft and the paddle to rotate. It can more precisely control the flow direction and speed of the fermentation broth. It helps to form a stable negative pressure area at the top cover, and more effectively attracts the floating scum above and the flow of the fermentation broth. At the same time, the process of the fermentation broth flowing into the built-in pump from the through holes of the transmission belt is smoother, reducing the hydrodynamic disorder and energy loss.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figures 1-3 : A fruit wine fermentation device with the function of enhancing aroma and color, comprises a fermentation tank 1, a built-in pump 2 is arranged in the fermentation tank 1, the built-in pump 2 comprises a top cover 21, a first rotating shaft 22 is rotatably arranged on the top cover 21, a paddle 221 is sleeved on the first rotating shaft 22, a rotating drive component 11 for driving the first rotating shaft 22 is arranged on the fermentation tank 1, a material shifting mechanism 3 for shifting scum is arranged on the top cover 21, and a transmission mechanism 4 is also arranged on the top cover 21, and the material shifting mechanism 3 is transmission-connected to the first rotating shaft 22 through the transmission mechanism 4.

[0033] The present invention realizes the function of controlling the scum to flow with the liquid through turbulence through the fermentation tank 1, the built-in pump 2 and the material-dispensing mechanism 3, thereby achieving the capping effect. At the same time, the material-dispensing action of the material-dispensing mechanism 3 can prevent the scum from contacting with the paddle 221 of the built-in pump 2 and being broken, thereby preventing the cell structure in the peel from being broken and affecting the taste and aroma of the fruit wine. While ensuring the quality of the fruit wine, the problem that the consistency and stability of the capping effect cannot be controlled by spraying for capping is solved. The rotary drive assembly 11 includes a rotary drive 111 and a main shaft 112 that is transmission-connected to the driving end of the rotary drive 111. The main shaft 112 penetrates the cover of the fermentation tank 1 and extends into the interior of the fermentation tank 1. The main shaft 112 is transmission-connected to the first rotating shaft 22, and the main shaft 112 is transmission-connected to the material-dispensing mechanism 3 through the transmission mechanism 4. A cylindrical shell for wrapping the blades 221 is connected to the top cover 21, a transmission shaft 25 is rotatably arranged on the shell, a bevel gear 24 is sleeved on the main shaft 112 and the first rotating shaft 22, first bevel gears 251 are sleeved on both ends of the transmission shaft 25, and two first bevel gears 251 are respectively meshed and connected with two bevel gears 24. A controller for human-machine interaction is provided on the fermentation tank 1, and the rotation driver 111 is preferably a servo motor, and the rotation driver 111 is electrically connected to the controller.

[0034] In the working state, the operator sends a signal to the rotary driver 111 through the controller. After receiving the signal, the rotary driver 111 drives the main shaft 112 to rotate. The main shaft 112 drives the first rotating shaft 22 to rotate through the transmission of the bevel gear 24 and the first bevel gear 251. The first rotating shaft 22 drives the paddle 221 to rotate, and then promotes the fermentation liquid to flow inside the fermentation tank 1. When the fermentation liquid flows, it will drive the upper layer of scum to flow, thereby achieving the effect of pushing the scum into the fermentation liquid to ensure uniform contact during the fermentation process. Let the wine and the peel get full contact, so as to extract more tannins, pigments and flavor substances. Compared with the traditional capping operation, the capping method through liquid flow can increase the dissolution of color and flavor in the peel residue and improve the flexibility and controllability of the fermentation process. At the same time, when the scum reaches the top of the built-in pump 2 with the flow of liquid, the scum is pushed to the side of the built-in pump 2 by the material-diverting mechanism 3 on the top cover 21, thereby preventing the scum from contacting with the paddle 221 and being broken, and stabilizing the fermentation quality of the fruit wine.

[0035] Reference Figures 3-5 The material-prying mechanism 3 includes at least two groups of material-prying components 31, and the material-prying component 31 includes a pulley 311 and a transmission belt 312. Two pulleys 311 are rotatably arranged on the top cover 21, and the pulley 311 is connected to the first rotating shaft 22 through the transmission mechanism 4. The transmission belt 312 connects the two pulleys 311. A through hole is opened on the transmission belt 312 for the fermentation liquid to pass through, and bristles 3121 are arranged on the transmission belt 312.

[0036] As the first embodiment of the material-dispensing mechanism 3, the present invention realizes the function of removing the scum through the pulley 311 and the transmission belt 312, and through the control of the transmission mechanism 4, the first rotating shaft 22 drives the pulley 311 to rotate while driving the blade 221 to rotate, and the pulley 311 drives the transmission belt 312 to rotate, and then the bristles 3121 attached to the transmission belt 312 are used to push the scum that flows to the blade 221 along with the fermentation liquid to the two sides of the top cover 21, so as to prevent the scum from contacting with the rotating blade 221 and being broken, thereby stabilizing the fermentation quality of the fruit wine. The top cover 21 is disc-shaped, and the transmission belt 312 extends radially along the top cover 21. Multiple groups of material-dispensing mechanisms 3 are distributed in a circular array along the axis of the top cover 21. During operation, when the rotary drive assembly 11 drives the first rotating shaft 22 and the paddle 221 to rotate, the rotating paddle 221 pushes the fermentation liquid to flow, thereby forming a negative pressure at the top cover 21, attracting the scum and fermentation liquid above to flow, and forming a suction port at each transmission belt 312, and the fermentation liquid flows into the built-in pump 2 from the through hole of the transmission belt 312. At the same time, the first rotating shaft 22 drives the pulley 311 to rotate through the transmission mechanism 4, and the pulley 311 drives the transmission belt 312 to rotate, so that the bristles 3121 of the part of the transmission belt 312 located above the top cover 21 always move outward from the center position of the top cover 21, thereby pushing the scum close to the top cover 21 with the flow of the fermentation liquid away, and preventing the scum from approaching the rotating paddle 221. The fermentation liquid enters the built-in pump 2 from the through hole on the transmission belt 312, and flows out from the bottom of the paddle 221 under the push of the built-in pump 2.

[0037] Reference Figures 3-7 The transmission mechanism 4 includes a first transmission assembly 41 and a synchronous transmission assembly 42. The first rotating shaft 22 is transmission-connected to the synchronous transmission assembly 42 through the first transmission assembly 41. The pulleys 311 of the multiple groups of material-shifting assemblies 31 are transmission-connected through the synchronous transmission assembly 42.

[0038] The present invention realizes the function of synchronously rotating the pulleys 311 of multiple material feeding components 31 by driving the first rotating shaft 22 through the first transmission component 41 and the synchronous transmission component 42. Furthermore, when the rotary drive component 11 drives the first rotating shaft 22 and the paddle 221 to rotate, the working of multiple material feeding components 31 can be synchronously controlled. It can more effectively cooperate to promote the flow of the fermentation liquid and the scum, thereby improving the processing efficiency of the entire system. The first transmission component 41 includes a first rotating gear 411, a planetary gear 412, a mounting ring 413, and a first toothed ring 414. The first rotating gear 411 is sleeved on the first rotating shaft 22. The planetary gear 412 and the mounting ring 413 are both rotatably arranged on the top cover 21. The first toothed ring 414 is sleeved on the mounting ring 413, and the axis of the mounting ring 413 is collinear with the axis of the first rotating shaft 22. The planetary gear 412 is meshed with both the first rotating gear 411 and the first toothed ring 414. The synchronous transmission component 42 includes a second toothed ring 421, a second rotating shaft 422, and a second rotating gear 423. The second toothed ring 421 is sleeved on the mounting ring 413. The second rotating shaft 422 is rotatably arranged on the top cover 21, and the second rotating shaft 422 is in transmission connection with the pulley 311. The second rotating gear 423 is sleeved on the second rotating shaft 422, and the second rotating gear 423 is meshed with the second toothed ring 421.

[0039] When the rotary drive component 11 drives the first rotating shaft 22 to rotate, the first rotating shaft 22 drives the first rotating gear 411 to rotate. The first rotating gear 411 drives the first toothed ring 414 to rotate through the planetary gear 412. The first toothed ring 414 drives the mounting ring 413 and the second toothed ring 421 to rotate. The second toothed ring 421 drives the second rotating gear 423 to rotate. The second rotating gear 423 drives the second rotating shaft 422 to rotate. The second rotating shaft 422 transmits the torque to the pulley 311, and then drives the transmission belt 312 to rotate for material feeding work. Through the synchronous rotation of multiple transmission belts 312, the energy waste and efficiency reduction caused by non-synchronization are avoided. And by using the synchronous transmission component 42 to synchronously control multiple material feeding components 31, the flow direction and speed of the fermentation liquid can be controlled more precisely. It helps to form a stable negative pressure area at the top cover 21, and more effectively attracts the scum and fermentation liquid above to flow. At the same time, the process of the fermentation liquid flowing into the built-in pump 2 from the through holes of the transmission belt 312 is also smoother, reducing the hydrodynamic disorder and energy loss.

[0040] Refer to Figure 8 and Figure 9 : A bracket 32 is provided on the top cover 21. A mounting shaft 321 is rotatably arranged on the bracket 32. A sieve plate 322 is sleeved on the mounting shaft 321. A second transmission component 43 is provided on the top cover 21. The mounting shaft 321 is in transmission connection with the first rotating shaft 22 through the second transmission component 43, and a through hole for the fermentation liquid to pass through is provided on the top cover 21.

[0041] As a second embodiment of the material-dispensing mechanism 3, the present invention realizes the function of removing scum through the bracket 32, the mounting shaft 321, the screen plate 322 and the second transmission assembly 43. The second transmission assembly 43 includes a third rotating shaft 431, a third rotating gear 432, a fourth rotating shaft 433 and a first bevel gear 251. The third rotating shaft 431 is rotatably arranged on the top cover 21, the third rotating gear 432 is sleeved on the third rotating shaft 431, and the third rotating gear 432 is transmission-connected with the first rotating shaft 22. The fourth rotating shaft 433 is rotatably arranged on the bracket 32, the fourth rotating shaft 433 is transmission-connected with the third rotating shaft 431, the fourth rotating shaft 433 and the mounting shaft 321 are both sleeved with a second bevel gear 434, and the two second bevel gears 434 are meshed and connected. In this embodiment, the third rotating shaft 431 is transmission-connected with the first rotating shaft 22 through the first transmission assembly 41. In the working state, when the first rotating shaft 22 rotates, the third rotating gear 432 is driven to rotate through the first transmission assembly 41, and the third rotating gear 432 drives the third rotating shaft 431 to rotate. The third rotating shaft 431 drives the fourth rotating shaft 433 to rotate through the synchronous belt, and the fourth rotating shaft 433 drives the mounting shaft 321 and the sieve plate 322 to rotate through the second bevel gear 434, and the scum is pushed away by the sieve plate 322, so that only the fermentation liquid passes through the sieve plate 322 and enters the housing of the built-in pump 2 from the through hole of the top cover 21.

[0042] Reference Figure 4 and Figure 10 : A mounting strip 33 is provided on the top cover 21 , and comb teeth 331 are provided on the mounting strip 33 . When the transmission belt 312 rotates, the comb teeth 331 rub against the bristles 3121 .

[0043] The present invention realizes the function of cleaning the scum adhering to the bristles 3121 of the transmission belt 312 through the mounting strip 33 and the comb teeth 331. As the transmission belt 312 rotates, the bristles 3121 on the transmission belt 312 will push the scum impacted by the water flow onto the transmission belt 312 to the two sides of the top cover 21. As the transmission belt 312 continues to work, some scum will still adhere to the bristles 3121, and move to the inside of the housing of the built-in pump 2 with the bristles 3121. For this purpose, a mounting strip 33 with comb teeth 331 is provided on the top cover 21. When the bristles 3121 on the transmission belt 312 located on the upper part of the top cover 21 enter the lower part of the top cover 21, they will first rub against the comb teeth 331, and then peel off the scum adhering to the bristles 3121.

[0044] Reference Figure 4 : A cover 211 for shielding the transmission mechanism 4 is provided on the top cover 21.

[0045] The present invention realizes the function of enclosing the transmission mechanism 4 through the cover 211 to prevent the scum from contacting the transmission mechanism 4. In order to drive the material stirring mechanism 3 by the rotation of the first rotating shaft 22, it is necessary to set the transmission mechanism 4 on the top cover 21. Once the scum contacts the gears or other moving parts of the transmission mechanism 4, it will also break under the pulling action. Therefore, a cover 211 for shielding the transmission mechanism 4 is provided to avoid the direct contact between the scum and the moving parts during the flow process.

[0046] Refer to Figure 2 and Figure 3 : There are at least three built-in pumps 2, and the multiple built-in pumps 2 are distributed in a circular array about the axis of the fermentation tank 1.

[0047] The present invention realizes the function of zoning operation by setting multiple built-in pumps 2. When only a single built-in pump 2 is set, the distribution of its negative pressure area is distributed around the main shaft 112, and a vortex will be formed around the axis of the main shaft 112. The scum will flow towards the center of the vortex under the impact, and then wind around the main shaft 112, resulting in the rupture of substances such as fruit peels under the rotational pulling action of the main shaft 112, affecting the quality of fruit wine fermentation. The circular array distribution of multiple built-in pumps 2 can ensure that the fluid in the fermentation tank 1 is subjected to a more uniform acting force. This helps to reduce the vortex and dead corners in the fluid, and improve the uniformity and mixing effect of the fermentation broth.

[0048] Refer to Figure 2 and Figure 11 : A support frame 12 is arranged in the fermentation tank 1, the built-in pump 2 is arranged on the support frame 12, and a bottom sieve 23 for filtering scum is provided at the bottom of the built-in pump 2.

[0049] The present invention realizes the function of supporting the built-in pump 2 and filtering the scum from the bottom of the built-in pump 2 through the support frame 12 and the bottom sieve 23. In order to improve the pressing effect, the rotary drive assembly 11 is usually set to work in a pulsed manner, that is, the main shaft 112 is controlled to rotate forward and reverse periodically through the rotary driver 111, and then the built-in pump 2 is controlled to perform periodic suction work, so that the scum is subjected to suction and thrust actions, and the scum is controlled to float up and down in the fermentation broth. Therefore, a bottom sieve 23 is provided at the bottom of the built-in pump 2. And because the scum will be subjected to alternating suction and thrust, it also avoids the scum adhering to the top cover 21, and can better carry out the fermentation work.

[0050] Refer to Figure 2 and Figure 11 : A linear drive assembly 13 for controlling the lifting of the support frame 12 is provided on the fermentation tank 1.

[0051] The present invention realizes the function of controlling the height of the built-in pump 2 through the linear drive assembly 13. The linear drive assembly 13 includes a guide rod and a screw rod, and a servo motor for driving the screw rod to rotate is provided on the fermentation tank 1. During fermentation production, the liquid level in the fermentation tank 1 will change. In order to better adapt to this change and maintain the stable operation of the built-in pump 2, a linear drive assembly 13 for adjusting the height of the built-in pump 2 is provided. The linear drive assembly 13 controls the lifting of the support frame 12, thereby driving the built-in pump 2 to lift. In this way, during the capping operation, the built-in pump 2 can be maintained at an appropriate working position, and stable feeding is performed through the feeding mechanism 3 to ensure the smooth progress of the fermentation process.

[0052] Referring to Figure 4 : A liquid level sensor 212 for detecting the water level is provided on the top cover 21.

[0053] The present invention realizes the function of sensing the change of the liquid level inside the fermentation tank 1 through the liquid level sensor 212, and cooperates with the linear drive assembly 13 to automatically control the height of the built-in pump 2. The liquid level sensor 212 is preferably a float type sensor. And the liquid level sensor 212 is electrically connected to the controller. During the fermentation process, the float type liquid level sensor 212 equipped on the top cover 21 monitors the change of the liquid level inside the fermentation tank 1 in real time and feeds back the signal to the controller; the controller judges whether it is necessary to adjust the height of the built-in pump 2 according to the preset liquid level parameters and sends a signal to the linear drive assembly 13. After receiving the signal, the linear drive assembly 13 drives the support frame 12 and the built-in pump 2 to lift to an appropriate position to ensure that the built-in pump 2 can operate in the best working state, and both the pumping efficiency and the head are optimized, so as to realize continuous stable capping operation and efficient material mixing.

[0054] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
