Description

Technical Field

[0001] The present invention relates to the technical field of alcohol beverage dealcoholization, and specifically to a dealcoholization device and method for alcohol beverage production. Background Art

[0002] Currently, the market demand for beverages with reduced alcohol content or even complete removal of alcohol has increased significantly. For the production of low-alcohol or alcohol-free wines, it is even more challenging to maintain attractive flavor characteristics that will be acceptable to consumers. Since beer can tolerate rougher treatment, in beer, the lost flavor can be partially restored by adding aroma substances recovered from yeast, but this method cannot be used to restore the flavor of wine.

[0003] The patent with the authorization announcement number CN109072148B discloses a device and method for alcohol beverage dealcoholization, including a first container including means for receiving an alcohol beverage, a second container including means for receiving a fluid, and a third container configured to receive the alcohol beverage from the first container, and the third container is further connected to the second container.

[0004] Although the above patent can conveniently dealcoholize alcohol beverages under ordinary conditions, so that the ethanol content removed from the alcohol beverage is forced to be diluted into a fluid, so that no ethanol distillate can be manufactured or taken out of the machine, during the production process of alcohol beverages, the original liquid produced after the fermentation of raw materials (such as fruits or grains) usually contains residual solid residues. When dealcoholization is carried out using a reverse osmosis membrane, these residues will adsorb on the membrane surface under the impact of liquid flow, forming a pollution layer, significantly reducing the permeation efficiency of water and ethanol, and affecting the dealcoholization effect. At the same time, a single dealcoholization technology has limitations: although the distillation method can effectively dealcoholize, the heating process will cause the loss of thermosensitive flavor substances, and the reverse osmosis membrane will show performance attenuation and structural damage at high temperatures (such as in the distillation link), resulting in difficulty in directly using the two in cooperation. Therefore, it is particularly important to effectively dealcoholize alcohol beverages by combining the advantages of different dealcoholization methods. Summary of the Invention

[0009] Furthermore, an installation shell is fixedly connected inside the alcohol removal tank. The installation frame is rotatably connected to the top of the installation shell. A sewage discharge pipe is fixedly connected to the bottom of the filter screen. The sewage discharge pipe sequentially penetrates through the bottom of the installation frame and the alcohol removal tank and is rotatably connected to the installation frame and the alcohol removal tank. A motor is fixedly connected inside the installation shell.

[0010] Furthermore, both of the driving wheels are coaxially and fixedly connected to the output end of the motor. The first driven wheel is coaxially and fixedly connected to the installation frame. A first transmission belt is connected in transmission between one of the driving wheels and the first driven wheel. The second driven wheel is coaxially and fixedly connected to the sewage discharge pipe. A second transmission belt is connected in transmission between the other driving wheel and the second driven wheel.

[0011] Furthermore, both the gear and the second toothed ring are rotatably connected to the bottom of the cover. The water spray pipe is fixedly connected to the second toothed ring. The first toothed ring is coaxially and fixedly connected to the top of the filter screen.

[0012] Furthermore, a connecting pipe is connected to the cover, and one end of the connecting pipe is fixedly sealed with the water spraying pipe. The other end of the connecting pipe penetrates through the cover and is rotatably connected to the cover.

[0013] Furthermore, a liquid discharge port is hermetically connected to the bottom of the flow guiding cover. A cavity is formed inside the side wall of the alcohol removal tank. An electric heating pipe is arranged inside the cavity, and the electric heating pipe is spirally wound inside the cavity.

[0014] The alcohol removal method of the alcohol removal equipment for alcohol beverage production is as follows: S1: Inject the stock solution into the alcohol removal tank from the liquid inlet on the cover. The stock solution first enters the filter screen. Start the motor to drive the driving wheel to rotate. The driving wheel drives the second driven wheel to rotate through the second transmission belt. The rotating second driven wheel drives the sewage pipe and the filter screen to rotate. With the help of the centrifugal force, the stock solution is driven to pass through the filter screen and enter the mounting rack. Blocked by the reverse osmosis membrane, the fixed residues in the stock solution are filtered into the filter screen. S2: When using the reverse osmosis membrane for alcohol removal, another rotating driving wheel drives the first driven wheel to rotate through the first transmission belt. The rotating first driven wheel drives the mounting rack and the reverse osmosis membrane to rotate. With the help of the centrifugal force, the ethanol and water in the stock solution are driven to pass through the reverse osmosis membrane and are centrally collected between the alcohol removal tank and the mounting shell. S3: When using the distillation method for alcohol removal, heat the electric heating pipe to heat the temperature to the boiling point of ethanol, so that ethanol vaporizes, condenses into a liquid state when encountering the flow guiding cover, and finally the ethanol with higher purity is centrally collected inside the flow guiding cover and can be discharged and collected through the liquid discharge port later. S4: When cleaning the filter screen, inject water into the water spraying pipe through the connecting pipe. The rotating filter screen drives the first toothed ring to rotate. The rotating first toothed ring drives the second toothed ring to rotate in the opposite direction through the meshing gear. The rotating second toothed ring drives the water spraying pipe to make a circular motion, so as to wash away the residues remaining on the side wall of the filter screen and discharge them through the sewage pipe. S5: When replacing the reverse osmosis membrane, open the cover, push the push block to drive the mounting ring to rotate. The rotating mounting ring drives the guiding block to stretch the third spring. At the same time, the guiding block pushes the L-shaped plate to move. The L-shaped plate drives the clamping block to retract into the mounting groove and compresses the first spring, so that the clamping block moves away from the top of the reverse osmosis membrane. At this time, the compressed second spring resets and pushes the top plate to move upward. The top plate pushes the reverse osmosis membrane out. After replacement, the reset first spring and third spring drive the clamping block to position the reverse osmosis membrane.

[0015] Beneficial effects: 1. By setting the filter screen to filter the solid residues in the stock solution, it prevents the fixed residues from adsorbing on the surface of the reverse osmosis membrane during alcohol removal, reducing the permeation efficiency of water and ethanol. Then, the electric heating pipe and the flow guiding cover are used to purify the removed ethanol and water. The electric heating pipe and the reverse osmosis membrane form a height difference, preventing high temperature from affecting the performance and structure of the reverse osmosis membrane.

[0016] 2. By setting a speed-changing component to adjust the rotation speeds of the filter screen and the reverse osmosis membrane, under the drive of the motor, the rotation speed of the reverse osmosis membrane is greater than that of the filter screen. The slowly rotating filter screen can prevent solid residues in the stock solution from adsorbing on the mesh wall and blocking the mesh holes, so as not to affect the normal filtration of the filter screen. The rapidly rotating reverse osmosis membrane can provide a greater centripetal force, which helps ethanol and water to pass through the reverse osmosis membrane and improves the alcohol removal efficiency.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As shown Figures 1-8 in the figure, the present invention provides a dealcoholization device for alcohol beverage production, including a dealcoholization tank 1. A diversion cover 2 is fixedly connected to the top of the dealcoholization tank 1. A cover 4 is threadedly connected to the top of the diversion cover 2. A liquid inlet 26 is provided on the cover 4. An installation frame 7 is arranged in the dealcoholization tank 1. A reverse osmosis membrane 12 is installed on the installation frame 7. A plurality of limiting mechanisms are arranged between the reverse osmosis membrane 12 and the installation frame 7. The limiting mechanism includes a clamping block 14, an L-shaped plate 15 and a first spring 16. The L-shaped plate 15 is fixedly connected between the clamping block 14 and the first spring 16. A drain port 3 is hermetically connected to the bottom of the diversion cover 2. A cavity is formed in the side wall of the dealcoholization tank 1. An electric heating tube 10 is arranged in the cavity, and the electric heating tube 10 is spirally wound in the cavity. By arranging a filter screen 8 to filter the solid residues in the stock solution, it is prevented that the fixed residues adsorb on the surface of the reverse osmosis membrane 12 during dealcoholization, reducing the permeation efficiency of water and ethanol. Then, the separated ethanol and water are purified by the electric heating tube 10 and the diversion cover 2. A height difference is formed between the electric heating tube 10 and the reverse osmosis membrane 12 to prevent high temperature from affecting the performance and structure of the reverse osmosis membrane 12. The top of the diversion cover 2 is conically inclined. Ethanol liquefies and adheres to the diversion cover 2, and will slide into the diversion cover 2 for collection due to the action of gravity. The diversion cover 2 is made of metal material, and the specific model selection adopts the existing technology in the field, so it will not be elaborated in detail here.

[0021] A filter screen 8 is arranged in the installation frame 7. A speed change assembly is arranged between the filter screen 8 and the reverse osmosis membrane 12. The speed change assembly includes a first driven wheel 22, a second driven wheel 24 and two driving wheels 21. By arranging the speed change assembly to adjust the rotation speeds of the filter screen 8 and the reverse osmosis membrane 12, an installation shell 6 is fixedly connected in the dealcoholization tank 1. The installation frame 7 is rotatably connected to the top of the installation shell 6. A sewage discharge pipe 9 is fixedly connected to the bottom of the filter screen 8. The sewage discharge pipe 9 sequentially penetrates through the bottom of the installation frame 7 and the dealcoholization tank 1, and is rotatably connected to the installation frame 7 and the dealcoholization tank 1. A motor 11 is fixedly connected in the installation shell 6. Both driving wheels 21 are coaxially fixed to the output end of the motor 11. The first driven wheel 22 is coaxially fixed to the installation frame 7. A first transmission belt 23 is connected between one of the driving wheels 21 and the first driven wheel 22. The second driven wheel 24 is coaxially fixed to the sewage discharge pipe 9. A second transmission belt 25 is connected between the other driving wheel 21 and the second driven wheel 24. Driven by the motor 11, the rotation speed of the reverse osmosis membrane 12 is greater than that of the filter screen 8. The filter screen 8 rotating at a low speed can prevent the solid residues in the stock solution from adsorbing on the mesh wall and blocking the mesh holes, so as not to affect the normal filtration of the filter screen 8. The reverse osmosis membrane 12 rotating at a high speed can provide a greater centripetal force, which helps ethanol and water to pass through the reverse osmosis membrane and improves the dealcoholization efficiency.

[0022] Below the cover 4, there is a water spray pipe 5. A linkage mechanism is provided between the water spray pipe 5 and the filter screen 8. The linkage mechanism includes a first gear ring 13, a gear 28, and a second gear ring 29. The gear 28 meshes and drives between the first gear ring 13 and the second gear ring 29. Both the gear 28 and the second gear ring 29 are rotatably connected to the bottom of the cover 4. The water spray pipe 5 is fixedly connected to the second gear ring 29. The first gear ring 13 is coaxially fixed to the top of the filter screen 8. A connecting pipe 27 is connected to the cover 4, and one end of the connecting pipe 27 is fixedly sealed with the water spray pipe 5. The other end of the connecting pipe 27 penetrates through the cover 4 and is rotatably connected to the cover 4. The connecting pipe 27 is arranged in an "L" shape. A plurality of high-pressure nozzles are hermetically connected to the water spray pipe 5. A solenoid valve is provided on the sewage discharge pipe 9 to control the flow of fluid. The high-pressure nozzles and the solenoid valve are both existing devices and will not be elaborated here. During use, water is injected into the connecting pipe 27 through an external water pipe and sprayed out through the high-pressure nozzles on the water spray pipe 5. The rotating filter screen 8 drives the first gear ring 13 to rotate. The rotating first gear ring 13 drives the second gear ring 29 to rotate in the opposite direction through the meshing gear 28. The rotating second gear ring 29 drives the water spray pipe 5 to perform a circular motion, thereby flushing the residue on the side wall of the filter screen 8 and discharging it through the sewage discharge pipe 9.

[0023] An installation groove is opened at the top of the mounting frame 7. The L-shaped plate 15 is slidably connected in the installation groove. The end of the first spring 16 is fixedly connected to the inner wall of the installation groove. An installation ring 17 is rotatably connected in the installation groove. A plurality of guide blocks 30 are fixedly connected to the installation ring 17. The guide blocks 30 are designed in a right trapezoid shape, and the side close to the L-shaped plate 15 is an inclined surface. A plurality of connecting plates 33 are fixedly connected in the installation groove. An arc-shaped rod 31 is fixedly connected to the side wall of the guide block 30, and the arc-shaped rod 31 slidably penetrates through the connecting plate 33. A third spring 32 is sleeved on the arc-shaped rod 31, and both ends of the third spring 32 are fixedly connected to the connecting plate 33 and the guide block 30 respectively. A plurality of arc-shaped holes are opened at the top of the installation groove. A plurality of push blocks 18 are fixedly connected to the top of the installation ring 17, and the plurality of push blocks 18 slide in the plurality of arc-shaped holes respectively. Below the reverse osmosis membrane 12, there is a top plate 19, and the top plate 19 is slidably connected to the mounting frame 7. A second spring 20 is provided at the bottom of the top plate 19, and both ends of the second spring 20 are fixedly connected to the top plate 19 and the mounting frame 7 respectively. During use, push the push block 18 to drive the installation ring 17 to rotate. The rotating installation ring 17 drives the guide block 30 to stretch the third spring 32. At the same time, the inclined surface of the guide block 30 pushes the L-shaped plate 15 to move. The L-shaped plate 15 drives the latch 14 to retract into the installation groove and compress the first spring 16, so that the latch 14 moves away from the top of the reverse osmosis membrane 12. At this time, the compressed second spring 20 resets and pushes the top plate 19 upward. The top plate 19 pushes the reverse osmosis membrane 12 out. After the reverse osmosis membrane 12 is taken out, release the push block 18. At this time, the stretched third spring 32 and the compressed first spring 16 drive the guide block 30 and the latch 14 to reset respectively. When installing a new reverse osmosis membrane 12, press the reverse osmosis membrane 12 into the installation frame 7. During this process, the bottom of the reverse osmosis membrane 12 presses the inclined surface of the latch 14, so that the latch 14 retracts into the installation groove and compresses the first spring 16. When the installation is about to be completed, the bottom of the reverse osmosis membrane 12 will press the top plate 19 to compress the second spring 20. When the reverse osmosis membrane 12 is installed, the top of the reverse osmosis membrane 12 moves below the latch 14. At this time, the latch 14 is no longer squeezed. The compressed first spring 16 resets and pushes the latch 14 out of the installation groove, so that the latch 14 moves above the reverse osmosis membrane 12. The bottom of the latch 14 limits the reverse osmosis membrane 12. It should be noted that the top of the latch 14 is designed to be inclined. When the latch 14 is at the maximum limit of protruding from the installation groove, the inclined surface end of the latch 14 is still inside the installation groove, ensuring that when installing the reverse osmosis membrane 12, the bottom of the reverse osmosis membrane 12 can contact the inclined surface of the latch 14.

[0024] The method for alcohol removal of the alcohol removal equipment for alcohol beverage production is as follows: S1: Inject the stock solution from the liquid inlet 26 on the sealing cover 4 into the alcohol removal tank 1. The stock solution first enters the filter net 8. Start the motor 11 to drive the driving wheel 21 to rotate. The driving wheel 21 drives the second driven wheel 24 to rotate through the second transmission belt 25. The rotating second driven wheel 24 drives the sewage pipe 9 and the filter net 8 to rotate. With the help of centrifugal force, the stock solution is driven to pass through the filter net 8 and enter the installation frame 7. Blocked by the reverse osmosis membrane 12, the fixed residues in the stock solution are filtered into the filter net 8. It should be noted that the motor 11 is connected to an external power supply through a wire. The external power supply includes a storage battery for providing electrical energy for the motor 11 and a control switch for controlling its start and stop. The external power supply is a prior art. The specific model and specification of the motor 11 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the prior art in this field, so it will not be elaborated in detail.

[0025] S2: When de-alcoholizing with the reverse osmosis membrane 12, another rotating driving wheel 21 drives the first driven wheel 22 to rotate through the first transmission belt 23. Rotating the first driven wheel 22 drives the mounting bracket 7 and the reverse osmosis membrane 12 to rotate. With the help of centrifugal force, ethanol and water in the stock solution are driven to pass through the reverse osmosis membrane 12 and are centrally collected between the de-alcoholization tank 1 and the mounting shell 6, which is convenient for the electric heating tube 10 to heat the ethanol and water. There is a height difference between the installation position of the electric heating tube 10 and the installation position of the reverse osmosis membrane 12, which can prevent high temperature from affecting the performance and structure of the reverse osmosis membrane 12.

[0026] S3: When de-alcoholizing by distillation method, heat the electric heating tube 10 to the boiling point of ethanol to vaporize the ethanol. The vaporized ethanol condenses into liquid when it meets the deflector 2. Finally, the ethanol with higher purity is centrally collected in the deflector 2 and can be discharged and collected through the drain port 3 later.

[0027] S4: When cleaning the filter screen 8, inject water into the water spray pipe 5 through the connecting pipe 27. The rotating filter screen 8 drives the first gear ring 13 to rotate. The rotating first gear ring 13 drives the second gear ring 29 to rotate in the opposite direction through the meshing gear 28. The rotating second gear ring 29 drives the water spray pipe 5 to make a circular motion, so as to wash away the residues remaining on the side wall of the filter screen 8 and discharge them through the sewage pipe 9.

[0028] S5: When replacing the reverse osmosis membrane 12, open the cover 4, push the push block 18 to drive the mounting ring 17 to rotate. The rotating mounting ring 17 drives the guide block 30 to stretch the third spring 32. At the same time, the guide block 30 pushes the L-shaped plate 15 to move. The L-shaped plate 15 drives the clamping block 14 to retract into the installation groove and compress the first spring 16, so that the clamping block 14 moves away from the top of the reverse osmosis membrane 12. At this time, the compressed second spring 20 resets and pushes the top plate 19 to move up. The top plate 19 pushes out the reverse osmosis membrane 12. After replacement, the reset first spring 16 and third spring 32 drive the clamping block 14 to position the reverse osmosis membrane 12.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

The rotating first driven wheel (22) drives the mounting bracket (7) and the reverse osmosis membrane (12) to rotate. With the aid of the centrifugal action, the ethanol and water in the original liquid are driven to pass through the reverse osmosis membrane (12) and are centrally collected between the de-alcoholization tank (1) and the mounting shell (6). S3: When de-alcoholizing by means of the distillation method, heat the electric heating pipe (10) to heat the temperature to the boiling point of ethanol, so that ethanol vaporizes, condenses into a liquid state when encountering the flow guide cover (2), and finally the ethanol with higher purity is centrally collected in the flow guide cover (2), and can be discharged and collected through the liquid discharge port (3) subsequently. S4: When cleaning the filter net (8), inject water into the water spray pipe (5) through the connecting pipe (27). The rotating filter net (8) drives the first toothed ring (13) to rotate. The rotating first toothed ring (13) drives the second toothed ring (29) to rotate in the opposite direction through the meshing gear (28). The rotating second toothed ring (29) drives the water spray pipe (5) to make a circular motion, so as to wash away the residues remaining on the side wall of the filter net (8) and discharge them through the sewage discharge pipe (9). S5: When replacing the reverse osmosis membrane (12), open the cover (4), push the push block (18) to drive the installation ring (17) to rotate. The rotating installation ring (17) drives the guide block (30) to stretch the third spring (32). At the same time, the guide block (30) pushes the L-shaped plate (15) to move. The L-shaped plate (15) drives the clamping block (14) to retract into the installation groove and compress the first spring (16), so that the clamping block (14) moves away from the top of the reverse osmosis membrane (12). At this time, the compressed second spring (20) resets and pushes the top plate (19) upward. The top plate (19) pushes the reverse osmosis membrane (12) out. After replacement, the reset first spring (16) and third spring (32) drive the clamping block (14) to position the reverse osmosis membrane (12).
