Description

Technical Field

[0001] The present invention relates to the technical field of dealcoholization of alcoholic beverages, in particular to a dealcoholization device and method for producing alcoholic beverages. Background Art

[0002] There is currently a significant increase in market demand for beverages with reduced alcohol content or even complete removal of alcohol. Maintaining an attractive flavor profile that will be accepted by consumers is even more challenging for producing low-alcohol or alcohol-free wines because beer can tolerate harsher treatments. In beer, lost flavor can be partially restored by adding aroma compounds recovered from yeast, but this approach cannot be used to restore the flavor of wine.

[0003] The patent with authorization publication number CN109072148B discloses an apparatus and method for dealcoholization of alcoholic beverages, comprising a first container including a device for receiving an alcoholic beverage, a second container including a device for receiving a fluid, and a third container configured to receive the alcoholic beverage from the first container, wherein the third container is further connected to the second container.

[0004] Although the above patent can conveniently dealcoholize alcoholic beverages under ordinary conditions, so that the ethanol content removed from the alcoholic beverage is forced to be diluted into a fluid so that no ethanol distillate can be made by the machine or taken out from the machine, in the production process of alcoholic beverages, the raw liquid produced after the fermentation of raw materials (such as fruits or grains) usually contains residual solid residues. When a reverse osmosis membrane is used for dealcoholization, these residues will be adsorbed on the membrane surface under the impact of liquid flow, forming a contamination layer, which significantly reduces the permeation efficiency of water and ethanol and affects 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 heat-sensitive flavor substances, and the reverse osmosis membrane will experience performance degradation and structural damage at high temperatures (such as the distillation stage), making it difficult for the two to be used directly in conjunction. Therefore, it is necessary to combine the advantages of different dealcoholization methods. It is particularly important to effectively dealcoholize alcoholic beverages. Summary of the Invention

[0011] Furthermore, a mounting shell is fixedly connected inside the dealcoholization box, the mounting frame is rotatably connected to the top of the mounting shell, a drain pipe is fixedly connected to the bottom of the filter screen, the drain pipe passes through the mounting frame and the bottom of the dealcoholization box in sequence, and is rotatably connected to the mounting frame and the dealcoholization box, and a motor is fixedly connected inside the mounting shell.

[0012] Furthermore, the two driving wheels are coaxially fixed to the output end of the motor, the first driven wheel is coaxially fixed to the mounting frame, a first transmission belt is connected between one of the driving wheels and the first driven wheel, the second driven wheel is coaxially fixed to the sewage pipe, and a second transmission belt is connected between the other driving wheel and the second driven wheel.

[0013] Furthermore, the gear and the second gear ring are both rotatably connected to the bottom of the cover, the water spray pipe is fixedly connected to the second gear ring, and the first gear ring is coaxially fixed to the top of the filter screen.

[0014] Furthermore, a connecting pipe is connected to the sealing cover, and one end of the connecting pipe is fixedly sealed with the water spray pipe, and the other end of the connecting pipe passes through the sealing cover and is rotatably connected to the sealing cover.

[0015] Furthermore, a drain port is sealed at the bottom of the deflector, a cavity is provided in the side wall of the dealcoholization tank, an electric heating tube is provided in the cavity, and the electric heating tube is spirally wound in the cavity.

[0016] The specific steps of the dealcoholization method of the dealcoholization equipment for the production of alcoholic beverages are as follows:

[0017] S1: The raw liquid is injected into the dealcoholization tank from the liquid inlet on the cover. The raw liquid first enters the filter screen. The starting motor drives 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 centrifugal force, the raw liquid passes through the filter screen and enters the installation frame. It is blocked by the reverse osmosis membrane, and the fixed residue in the raw liquid is filtered into the filter screen.

[0018] S2: When the reverse osmosis membrane is used for dealcoholization, another rotating driving wheel drives the first driven wheel to rotate through the first transmission belt. The rotation of the first driven wheel drives the mounting frame and the reverse osmosis membrane to rotate. The ethanol and water in the raw liquid are driven through the reverse osmosis membrane by centrifugal action and are collected between the dealcoholization tank and the mounting shell.

[0019] S3: When dealcoholization is carried out by distillation, the electric heating tube is heated to the boiling point of ethanol, causing the ethanol to vaporize and condense into liquid when it encounters the guide cover. Finally, the higher-purity ethanol is collected in the guide cover and can be discharged and collected through the drain port.

[0020] S4: When cleaning the filter, water is injected into the water spray pipe through the connecting pipe. The rotating filter drives the first gear ring to rotate. The rotating first gear ring drives the second gear ring to rotate in the opposite direction through the meshing gear. The rotating second gear ring drives the water spray pipe to make a circular motion, thereby washing away the residue remaining on the side wall of the filter and discharging it through the sewage pipe.

[0021] S5: When replacing the reverse osmosis membrane, open the cover, push the push block to drive the installation ring to rotate, the rotating installation ring drives the guide block to stretch the third spring, and at the same time the guide block pushes the L-shaped plate to move, the L-shaped plate drives the card block to retract into the installation groove and compress the first spring, so that the card block moves away from the top of the reverse osmosis membrane. At this time, the compressed second spring resets and pushes the top plate up, and the top plate pushes the reverse osmosis membrane out. After replacement, the reset first spring and the third spring drive the card block to position the reverse osmosis membrane.

[0022] Beneficial effects: 1. The solid residue in the raw liquid is filtered by setting a filter to prevent the fixed residue from being adsorbed on the surface of the reverse osmosis membrane during dealcoholization, thereby reducing the permeation efficiency of water and ethanol. The ethanol and water removed are then purified by the electric heating tube and the guide cover. The electric heating tube and the reverse osmosis membrane form a height difference to prevent high temperature from affecting the performance and structure of the reverse osmosis membrane.

[0023] 2. The speed of the filter and reverse osmosis membrane is adjusted by setting the speed change component. Driven by the motor, the speed of the reverse osmosis membrane is greater than the speed of the filter. The low-speed rotating filter can prevent the solid residue in the raw liquid from being adsorbed on the mesh wall and clogging the mesh holes, so as not to affect the normal filtration of the filter. The high-speed rotating reverse osmosis membrane can provide greater centripetal force, which helps ethanol and water pass through the reverse osmosis membrane and improve the dealcoholization efficiency.

The ethanol and water removed are then purified by the electric heating tube 10 and the flow guide 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 flow guide cover 2 is conically inclined, and the ethanol liquefies and adheres to the flow guide cover 2. It will slide into the flow guide cover 2 due to the action of gravity and be collected. The flow guide cover 2 is made of metal material, and the specific selection adopts the existing technology in this field, so it will not be described in detail.

[0035] A filter screen 8 is provided in the mounting frame 7, and a speed change assembly is provided 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.

A motor 11 is fixedly connected in the mounting shell 6, and the two driving wheels 21 are coaxially fixed with the output end of the motor 11.

Driven by the motor 11, the rotation speed of the reverse osmosis membrane 12 is greater than the rotation speed of the filter screen 8. The low-speed rotating filter screen 8 can prevent the solid residue in the raw liquid from being adsorbed on the mesh wall and clogging the mesh holes, so as not to affect the normal filtration of the filter screen 8. The high-speed rotating reverse osmosis membrane 12 can provide greater centripetal force, which helps ethanol and water to pass through the reverse osmosis membrane and improve the dealcoholization efficiency.

[0036] A water spray pipe 5 is provided below the cover 4, and 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 is meshed and transmitted between the first gear ring 13 and the second gear ring 29. The gear 28 and the second gear ring 29 are both rotatably connected to the bottom of the cover 4, and 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 passes 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 sealed and connected to the water spray pipe 5. A solenoid valve is provided on the sewage pipe 9 to control the circulation of the fluid. The high-pressure nozzle and the solenoid valve are both existing devices and will not be elaborated on here.

[0037] During use, water is injected into the connecting pipe 27 through an external water pipe, and is sprayed out through the high-pressure nozzle on the water spray pipe 5. The rotating filter screen 8 drives the first gear ring 13 to rotate, and 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 washing away the residue remaining on the side wall of the filter screen 8 and discharging it through the sewage pipe 9.

[0038] A mounting groove is provided on the top of the mounting frame 7, and the L-shaped plate 15 is slidably connected in the mounting groove. The end of the first spring 16 is fixedly connected to the inner wall of the mounting groove. A mounting ring 17 is rotatably connected in the mounting groove. A plurality of guide blocks 30 are fixedly connected to the mounting ring 17. The guide blocks 30 are designed in a right-angled trapezoidal 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 mounting groove. An arc rod 31 is fixedly connected to the side wall of the guide block 30, and the arc rod 31 slides through the connecting plate 33. A third spring 32 is sleeved on 31, and the two 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 mounting groove, and a plurality of push blocks 18 are fixedly connected to the top of the mounting ring 17, and the plurality of push blocks 18 slide in the plurality of arc-shaped holes respectively.

A second spring 20 is provided at the bottom of the top plate 19, and the two ends of the second spring 20 are fixedly connected to the top plate 19 and the mounting frame 7 respectively.

[0039] When in use, push the push block 18 to drive the mounting ring 17 to rotate, and the rotating mounting 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, and the L-shaped plate 15 drives the card block 14 to retract into the mounting groove and compress the first spring 16, so that the card block 14 is removed from the top of the reverse osmosis membrane 12. At this time, the compressed second spring 20 is reset to push the top plate 19 to move upward, and the top plate 19 pushes the reverse osmosis membrane 12 out. After the reverse osmosis membrane 12 is taken out, the push block 18 is released. At this time, the stretched third spring 32 and the compressed first spring 16 respectively drive the guide block 30 and the card block 14 to reset. When installing a new reverse osmosis membrane 12, the reverse osmosis membrane 12 is pressed into the mounting frame 7. In this process, the bottom of the reverse osmosis membrane 12 squeezes the tilt of the card block 14 14, and the bottom of the block 14 is limited to the reverse osmosis membrane 12. It should be noted that the top of the block 14 is tilted. When the block 14 is at the maximum limit of stretching out the mounting groove, one end of the inclined surface of the block 14 is still in the mounting groove. When the reverse osmosis membrane 12 is installed, the top of the reverse osmosis membrane 12 moves to the bottom of the block 14.

[0040] The specific steps of the dealcoholization method of the dealcoholization equipment for the production of alcoholic beverages are as follows:

[0041] S1: The raw liquid is injected into the dealcoholization tank 1 from the liquid inlet 26 on the cover 4. The raw liquid first enters the filter 8. The starting motor 11 drives 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 8 to rotate. With the help of centrifugal action, the raw liquid is driven to pass through the filter 8 and enter the mounting frame 7. It is blocked by the reverse osmosis membrane 12, and the fixed residue in the raw liquid is filtered into the filter 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 battery for providing electrical energy to 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 specifications of the motor 11 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the prior art in this field, so it will not be described in detail.

[0042] S2: When the reverse osmosis membrane 12 is used for dealcoholization, another rotating driving wheel 21 drives the first driven wheel 22 to rotate through the first transmission belt 23, and the rotating first driven wheel 22 drives the mounting frame 7 and the reverse osmosis membrane 12 to rotate. The ethanol and water in the raw liquid are driven to pass through the reverse osmosis membrane 12 by means of centrifugal action and are collected between the dealcoholization box 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.

[0043] S3: When dealcoholization is carried out by distillation, the electric heating tube 10 is heated to the boiling point of ethanol, so that the ethanol is vaporized and condensed into liquid when it encounters the guide cover 2. Finally, the ethanol with higher purity is collected in the guide cover 2 and can be discharged and collected through the drain port 3.

[0044] S4: When cleaning the filter screen 8, water is injected 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 perform a circular motion, thereby washing away the residue remaining on the side wall of the filter screen 8 and discharging it through the sewage pipe 9.

[0045] 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, and 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, and the L-shaped plate 15 drives the card block 14 to retract into the mounting groove and compress the first spring 16, so that the card block 14 is moved away from the top of the reverse osmosis membrane 12. At this time, the compressed second spring 20 is reset to push the top plate 19 to move upward, and the top plate 19 pushes the reverse osmosis membrane 12 out. After replacement, the reset first spring 16 and the third spring 32 drive the card block 14 to position the reverse osmosis membrane 12.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.

Finally, the ethanol with higher purity is collected in the guide cover (2) and can be discharged and collected through the drain port (3) later. S4: When cleaning the filter (8), water is injected into the water spray pipe (5) through the connecting pipe (27), and the rotating filter (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, thereby washing away the residue remaining on the side wall of the filter (8) and discharging it through the sewage 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, and 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, and 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 the third spring (32) drive the clamping block (14) to position the reverse osmosis membrane (12).
