Description

Technical Field

[0001] This utility model relates to the field of brewing, and in particular to a distillation device for baijiu (Chinese liquor). Background Technology

[0002] In existing brewing processes, the method involves mixing raw materials such as mash, crushed and moistened grains, and rice husks, then loading them into a still. Steam is then introduced into the bottom of the still for distillation. During the mixing and loading process, a mixer is used to stir the mixture, which is then transferred to the still via a grab bucket. Steam is then introduced into the still for distillation. Each still is distilled, and the mixture is unloaded after each distillation, repeating the process. The still, as a key piece of equipment in the distillation process, has its design and performance significantly impacting the entire process. Currently, there are many problems with the stills and related equipment used in the brewing industry that urgently need to be addressed.

[0003] During the distillation of baijiu (Chinese white liquor), although the liquid components in the mash evaporate to form baijiu vapor under high temperatures, due to various factors, some baijiu vapor still contains small amounts of baijiu liquid, water vapor, or other liquid media. These liquid media are not well separated, ultimately affecting the taste of the finished baijiu. Furthermore, in traditional distillation equipment, the lid of the still is typically designed with a single structure, lacking an efficient heat management mechanism. This allows heat from the steam inside the still to easily dissipate through the lid, reducing distillation efficiency, increasing production costs, and making it difficult to ensure complete distillation, resulting in inconsistent liquor quality. Simultaneously, when the grain packing material inside the still is unevenly distributed, the steam generation rate varies significantly in local areas. For example, high-density areas evaporate slowly, further exacerbating the heat transfer imbalance and steam distribution fluctuations, affecting distillation stability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a liquor distillation device in light of the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A distillation apparatus for baijiu (Chinese liquor) includes a main body comprising a tank, a lid-lifting device, a lid unit that can be sealed or detachably connected to the tank via the lid-lifting device, a condenser disposed outside the tank, a steam supply pipeline connected between the condenser and the lid unit, and a liquor receiving unit connected to the condenser. A condensation unit is disposed on the side of the lid unit closest to the tank. A steam outlet is disposed on the lid unit. A water vapor separation device for separating steam from water vapor is disposed between the steam outlet and the steam supply pipeline.

[0007] The aforementioned components achieve the following effects: The tank body serves as a storage container for the distilled spirits; the lifting cap device allows for easy repositioning of the cap unit, enabling users to place it on top of the tank during distillation and remove it when not in use; the steam delivery channel, interconnected with the condenser, allows the distilled spirit vapor to enter the condenser for cooling and liquefaction; and... The system incorporates a receiving unit, allowing liquefied liquor to be stored within it. A condensing unit, located near the tank body, condenses and liquefies the distilled liquor vapor and water vapor, allowing them to fall into the tank, thus achieving secondary distillation and isolating some water vapor. A steam outlet facilitates the transport of distilled liquor vapor. Finally, a water vapor separator separates the steam and water vapor entering the steam outlet, preventing excessive water vapor from liquefying and affecting the taste of the liquor.

[0008] Preferably, the condensation unit includes, but is not limited to, a condenser tube arranged in a spiral shape inside the cover unit, wherein the condenser tube extends outward from the cover unit and is provided with an inlet and an outlet; and a condensing medium is provided outside the condenser tube.

[0009] The effects achieved by the above-mentioned components are as follows: By incorporating condenser tubes, which are not limited to those arranged in a spiral shape within the cap unit, the cooling effect is improved, significantly increasing the contact area and contact time between the condenser tubes and the condensing medium. This allows water vapor to be more fully condensed and liquefied when it comes into contact with the cap unit, falling into the tank. The liquor vapor can adhere to the lower surface of the cap unit, optimizing the distillation effect and contributing to improved liquor quality and yield. The inclusion of a condensing medium enhances the condensation and cooling effect. The presence of inlet and outlet water allows for the connection of external circulating water through the condenser tubes to achieve efficient heat exchange, enabling precise control of condensation temperature and rate, and enhancing the condensation effect.

[0010] Preferably, the water vapor separation device includes either a spiral structure or a baffle structure.

[0011] The effect achieved by the above components is that by setting different structures for the water vapor separation device, different structures can be used to isolate water vapor when distilling different distillation processes or different grains, thereby increasing the versatility of the structure in use.

[0012] Preferably, the spiral structure is formed by a plurality of uniformly arranged curved baffles spiraling upwards.

[0013] The effect achieved by the above-mentioned components is as follows: by setting up a spiral structure and the baffle is spirally upward, the water vapor is blocked by the curved baffle and cannot rise, thus playing the role of blocking water vapor.

[0014] Preferably, the baffle structure includes multiple baffles fixed on the inner wall of the channel, the baffles being of different lengths and arranged at an angle.

[0015] The effect achieved by the above-mentioned components is that by setting up a baffle structure with the baffle plate set at an angle, water vapor is blocked by the angled baffle plate and cannot rise, thus playing the role of blocking water vapor.

[0016] Preferably, a spraying device is rotatably arranged inside the cover unit; the spraying device includes a liquid inlet pipe, a rotating structure located at the lower end of the liquid inlet pipe, and a spraying pipe connected to the liquid inlet pipe through the rotating structure; a spraying nozzle is eccentrically arranged on the spraying pipe.

[0017] The effects achieved by the above components are as follows: by setting up a rotatable spray pipe device, users can add water to the grain inside the tank without opening the cover unit, and the rotating structure makes the watering more uniform; the spray nozzle is set off eccentrically so that the water sprayed out can drive the spray pipe to rotate with the rotating structure during the spraying process.

[0018] Preferably, a temperature and pressure control structure is provided at any position on the steam outlet; the temperature and pressure control structure includes a temperature control unit and a pressure control unit; the temperature control unit is obstructed at the upper end of the water-vapor separator; the pressure control unit is provided at any position on the steam outlet.

[0019] The aforementioned components achieve the following effects: by setting up a temperature control unit, they can detect the temperature inside the steam outlet; by setting up a pressure control unit, they can detect the pressure generated inside the equipment during the distillation of baijiu.

[0020] Preferably, a flow guiding structure is provided below the steam inlet; the flow guiding structure includes a funnel-shaped flow guiding cover that expands outward from top to bottom and is provided below the steam inlet, and the flow guiding cover is fixedly connected to the inner wall of the cover unit by several support legs.

[0021] The effect achieved by the above components is that, by setting up a flow guiding structure, the liquor vapor or water vapor will not directly enter the steam outlet, thus preventing the temperature from being too high or the pressure from being too high.

[0022] Preferably, the condenser is provided with a delivery pipe; both the water inlet and the water outlet are connected to the condenser through the delivery pipe; and a three-way valve is provided on the delivery pipe.

[0023] The aforementioned components achieve the following effects: by setting up a delivery pipe, they serve to transport the liquid inside the condenser; by setting up a three-way valve, they allow the liquid to be transported or canceled through the three-way valve.

[0024] Preferably, the cover unit is also provided with a water inlet pipe connected to the liquid inlet pipe.

[0025] The effect achieved by the above-mentioned components is that, by setting up a water inlet pipe, water can enter the liquid inlet pipe through the water inlet pipe and then be sprayed out from the spray device, thus playing the role of introducing water.

[0038] like Figures 1 to 5 As shown, this utility model provides

[0039] A distillation apparatus for baijiu (Chinese liquor) includes a main body 1, which comprises a tank 11, a lid-lifting device 12, a lid unit 2 that can be sealed or detachably connected to the tank 11 via the lid-lifting device 12, a condenser 13 disposed outside the tank 11, a steam transmission pipeline 14 connecting the condenser 13 and the lid unit 2, and a liquor receiving unit 15 connected to the condenser 13. A condensing unit 21 is disposed on the side of the lid unit 2 closest to the tank 11. The lid unit 2 is equipped with... Steam outlet 3; A water vapor separation device 4 for separating steam and water vapor is provided between the steam outlet 3 and the steam pipeline 14; After the grain is placed in the tank 11 for distillation and heating, it is atomized into liquor vapor. The liquor vapor is condensed and liquefied through the condensation unit 21 and then distilled again and liquefied into water vapor. The distilled liquor vapor enters the steam outlet 3, and after passing through the water vapor separation device 4 and the steam pipeline 14, it enters the condenser 13 for condensation and liquefaction, and then flows to the liquor receiving unit 15 to form liquor. The tank 11 serves as a storage unit for the distilled liquor. The lifting cap device 12 allows for easy repositioning of the cap unit 2. When distillation is needed, the cap unit 2 can be placed on top of the tank 11 using the lifting cap device 12; when distillation is not needed, the cap unit 2 can be removed from the tank 11 using the lifting cap device 12. A steam delivery channel, connected to the condenser 13, allows the distilled liquor vapor to enter the condenser 13 for cooling and liquefaction. The receiving unit 15 allows the liquefied liquor to enter and be stored. A condensing unit 21 is provided on the side of the cover unit 2 near the tank body 11, which allows the distilled liquor vapor and water vapor to be condensed and liquefied, falling into the tank body 11, thus achieving secondary distillation and isolating some water vapor. A steam outlet 3 is provided to transport the distilled liquor vapor. A water vapor separator 4 is provided to separate the steam and water vapor entering the steam outlet 3, preventing excessive water vapor from condensing and affecting the taste of the liquor.

[0040] The condensing unit 21 includes, but is not limited to, a condenser tube 22 arranged in a spiral shape within the cover unit 2. The condenser tube 22 extends outward from the cover unit 2 and is provided with an inlet 23 and an outlet 24. A condensing medium is provided outside the condenser tube 22. By providing the condenser tube 22, and by including, but not limited to, its spiral arrangement within the cover unit 2, the cooling effect is improved, significantly increasing the contact area and contact time between the condenser tube 22 and the condensing medium. This allows water vapor to be more fully condensed and liquefied when it comes into contact with the cover unit 2, falling into the tank 11. The liquor vapor can adhere to the lower surface of the cover unit 2, optimizing the distillation effect and helping to improve the quality and yield of the liquor. The condensing medium improves the condensation and cooling effect. The inlet 23 and outlet 24 allow external circulating water to be connected through the condenser tube 22 for efficient heat exchange, enabling precise control of the condensation temperature and rate, and enhancing the condensation effect.

[0041] The condensing medium described in this utility model can be any medium that can be used for cooling and temperature reduction. This medium will not be specifically described in this utility model. The cooling medium is a conventional and well-known structural technology for those skilled in the art.

[0042] The cover unit 2 is provided with a heat insulation layer 25, which is located above the condensation unit 21. The heat insulation layer 25 can effectively reduce heat loss in the tank 11, reduce energy consumption, and maintain a stable high temperature environment in the tank 11, which is conducive to continuous distillation.

[0043] The water vapor separation device 4 includes either a spiral structure 41 or a baffle structure 42. By providing different structures for the water vapor separation device 4, different structures can be used to isolate water vapor when distilling different processes or different grains, thus improving the versatility of the structure in use.

[0044] The spiral structure 41 is formed by a number of uniformly arranged curved baffles 43 spiraling upwards. By setting the spiral structure 41 and the baffles 43 spiraling upwards, water vapor is blocked by the curved baffles 43 and cannot rise, thus blocking water vapor. When the liquor vapor enters the spiral structure 41 upwards, it generates a vapor vortex and centrifugal force under the action of the spiral structure 41. The liquid medium in the liquor vapor is thrown onto the inner wall of the steam outlet 3 under the action of centrifugal force. The liquid medium slides down along the inner wall of the steam outlet 3 and the baffles 43, while the liquor vapor continues to rise along the steam outlet 3.

[0045] The baffle structure 42 includes multiple baffle plates 43 fixed to the inner wall of the channel. The baffle plates 43 are of different lengths and are arranged at an angle. By setting up the baffle structure 42 and the baffle plates 43 are arranged at an angle, water vapor is blocked by the inclined baffle plates 43 and cannot rise, thus blocking water vapor. When the liquor vapor in the steam outlet 3 flows upward and hits the baffle structure 42, the liquid medium in the liquor vapor is thrown onto the inner wall of the steam outlet 3 under the action of centrifugal force. The liquid medium slides down along the inner wall of the steam outlet 3 and the baffle plates 43, while the liquor vapor continues to rise along the steam outlet 3. The baffle plates 43 are made of high temperature and corrosion resistant materials.

[0046] A spraying device 5 is rotatably installed inside the cover unit 2. The spraying device 5 includes an inlet pipe 51, a rotating structure 52 located at the lower end of the inlet pipe 51, and a spraying pipe 53 connected to the inlet pipe 51 via the rotating structure 52. A spraying nozzle 54 is eccentrically arranged on the spraying pipe 53. By providing a rotatable spraying pipe 53, the user can add water to the grain stored in the tank 11 without opening the cover unit 2. The rotating structure 52 ensures more even watering. The eccentric arrangement of the spraying nozzle 54 allows the sprayed water to drive the spraying pipe 53 to rotate along with the rotating structure 52 during spraying. The rotating structure 52 in this invention can be any rotatable component structure, and this invention does not limit the structure to a single type. The rotation method and function are conventional and well-known technologies and structures for those skilled in the art, and do not require further description.

[0047] A temperature and pressure control structure 31 is located at any position on the steam outlet 3. The temperature and pressure control structure 31 includes a temperature control unit 32 and a pressure control unit 33. The temperature control unit 32 is located at the upper end of the water-vapor separation device 4. The pressure control unit 33 is located at any position on the steam outlet 3. By setting up the temperature control unit, the temperature inside the steam outlet 3 is detected. By setting up the pressure control unit 33, the pressure generated inside the equipment during the distillation of baijiu is detected.

[0048] A flow guiding structure 6 is provided below the steam outlet 3. The flow guiding structure 6 includes a funnel-shaped flow guide hood 61 that expands outward from top to bottom below the steam outlet 3. The flow guide hood 61 is fixedly connected to the inner wall of the lid unit 2 by several support legs 62. By providing the flow guiding structure 6, the liquor vapor or water vapor will not directly enter the steam outlet 3, preventing excessively high temperature or pressure. A flow channel for the liquor vapor is formed between the outer wall of the flow guide hood 61 and the inner wall of the lid unit 2, and the flow channel connects the interior of the inner wall of the lid unit 2 and the interior of the steam outlet 3.

[0049] The condenser 13 is provided with a delivery pipe 16; the inlet 23 and outlet 24 are both connected to the condenser 13 through the delivery pipe 16; a three-way valve 17 is provided on the delivery pipe 16. The delivery pipe 16 serves to deliver liquid inside the condenser 13; the three-way valve 17 allows the liquid to be delivered or canceled through the three-way valve 17.

[0050] The cover unit 2 is also provided with a water inlet pipe 18 connected to the liquid inlet pipe 51. By providing the water inlet pipe 18, water can enter the liquid inlet pipe 51 through the water inlet pipe 18 and then be sprayed out from the spray device 5, which serves to introduce water.

[0051] The temperature control unit 32 includes a temperature valve 34, which is located inside the steam outlet 3 and the bottom of the temperature valve 34 does not contact the water vapor separation device 4. The outer edge of the temperature valve 34 is fixedly connected to the inner wall of the steam outlet 3. The liquor vapor passing through the water vapor separation device 4 can only pass through the temperature valve 34 and continue to rise along the steam pipeline 14 when the temperature valve 34 is open.

[0052] The temperature valve 34 is equipped with a temperature sensing unit and a first control unit. The first control unit, the temperature sensing unit, and the temperature valve 344 are all electrically connected to each other. When the temperature sensing unit senses that the temperature of the liquor vapor inside the steam outlet 3 is greater than 80°C, the first control unit controls the temperature valve 34 to open, and the liquor vapor continues to rise along the steam pipeline 14 through the temperature valve 34.

[0053] The temperature sensing unit is a temperature sensor that can sense temperature and convert it into a usable output signal. This utility model uses a contact temperature sensor. The first control unit is a high-temperature and high-pressure resistant electronic control board. The electronic control board integrates an input device and an output device. The temperature valve 34 is a pneumatic large-orifice butterfly valve. The contact temperature sensor is electrically inductively connected to the input device on the electronic control board, and the pneumatic large-orifice butterfly valve is electrically inductively connected to the output device on the electronic control board. The working principle is that when the contact temperature sensor senses that the temperature of the liquor vapor inside the steam outlet 3 is greater than 80°C, the contact temperature sensor transmits the temperature sensing signal to the input device on the electronic control board. The electronic control board converts this signal and outputs it from the output device to the pneumatic large-orifice butterfly valve, which is then activated and opened.

[0054] The pressure control unit 33 includes a high-pressure valve 35 and a low-pressure valve 36. The high-pressure valve 35 is located on the outer wall of the steam outlet 3, and the low-pressure valve 36 is located on the temperature valve 34. The pressure control unit 33 also includes a pressure sensing unit and a second control unit located on the inner wall of the steam outlet 3. The pressure sensing unit, the second control unit, the high-pressure valve 35, and the low-pressure valve 36 are all electrically inductively connected. The pressure sensing unit senses the pressure inside the steam outlet 3. When the pressure is high, the second control unit controls the high-pressure valve 35 to open and release pressure. When the pressure is low, the second control unit controls the low-pressure valve 36 to open and release pressure.

[0055] Specifically, when the pressure sensing unit senses that the pressure inside the steam outlet 3 is greater than 0.7 MPa, it is considered high pressure, and the second control unit controls the high pressure valve 35 to open and release pressure; when the pressure sensing unit senses that the pressure inside the steam outlet 3 is greater than 0.1 MPa and less than 0.7 MPa, it is considered low pressure, and the second control unit controls the low pressure valve 36 to open and release pressure.

[0056] The pressure sensing unit is a pressure sensor that can sense pressure signals and convert them into usable output electrical signals according to a certain rule. This invention uses a gas pressure sensor for measuring vapor pressure, which can measure and control gas pressure in the range of 100 kPa to 10 MPa. The second control unit is a high-temperature and high-pressure resistant electronic control board, which integrates input and output devices. Both the high-pressure valve 35 and the low-pressure valve 36 are small-orifice electrically controlled valves. The gas pressure sensor is electrically inductively connected to the input device on the electronic control board, and the small-orifice electrically controlled valves are electrically inductively connected to the output device on the electronic control board. The working principle is as follows: when the gas pressure sensor senses that the pressure inside the steam inlet 3 is greater than 0.7 MPa, the gas pressure sensor transmits the pressure sensing signal to the input device on the electronic control board. The electronic control board converts this signal and outputs it from the output device to the high-pressure valve 35, which is then activated to open and release pressure. When the gas pressure sensor senses that the pressure inside the steam inlet 3 is greater than 0.1 MPa and less than 0.7 MPa, the gas pressure sensor transmits the pressure sensing signal to the input device on the electronic control board. The electronic control board converts this signal and outputs it from the output device to the low-pressure valve 36, which is then activated to open and release pressure.

[0057] In this utility model, the specific electrical working control principle and signal sensing and transmission principle inside the temperature and pressure control structure 31 are technical means commonly used and easily conceived by those skilled in the art, so they will not be described in detail.

[0058] In this invention, the condenser 13 is externally connected to an inlet water supply. After passing through the three-way valve 17 from the delivery pipe 16, the fluid enters the condenser 13 and the inlet 23 respectively. After entering the condenser 13, the fluid cools and liquefies the liquor vapor and enters the condensation unit 21 to cool and liquefy the water vapor in the cap unit 2. The fluid then enters the delivery pipe 16 through the outlet 24, and the fluid in the condenser 13 is also discharged. Subsequently, it is discharged through the three-way valve 17 to form the condensation channel 7.

[0059] In this utility model, the liquor vapor in the cover unit 2 passes through the guide structure 6, the steam outlet 3, the temperature and pressure control unit 33, the steam pipeline 14, the condenser 13 and the liquor receiving unit 15 in sequence to form the liquefaction channel 8.

[0060] In this invention, water enters the position of the liquid inlet pipe 51 through the water inlet pipe 18, and then is discharged through the spray nozzle 54 on the spray device 5 to form the water spray channel 9.

[0061] Figure 5 In the diagram, B is the unit module that supplies water to the spray device 5; C is the unit module that supplies water to and drains the condenser 13.

[0062] In this embodiment: The user first places the grain to be distilled into the tank 11, and then places the lid unit 2 above the tank 11 using the lid lifting device 12. At this time, fluid can enter the liquid inlet pipe 51 through the water inlet pipe 18, and then the water enters the spray pipe 53 and is sprayed through the spray nozzle 54. Because the rotating structure 52 is set and the spray nozzle 54 is eccentrically set, the spray pipe 53 will rotate and spray water inside the lid unit 2. At this time, the grain in the tank 11 will undergo distillation. Because the boiling point of water is different from that of alcohol, during the distillation process, water vapor and liquor vapor will rise together. At this time, the liquor vapor will... First, the water vapor adheres to the lower surface of the cover unit 2. Then, it liquefies through the condensation unit 21 and falls back into the tank 11, thus forming a secondary distillation effect. The liquor vapor in the cover unit 2 impacts the guide hood 61, where it is buffered and diffuses downwards along the wall of the guide hood 61 until it exits. Since the liquor vapor still needs to rise, it enters the flow channel between the outer wall of the guide hood 61 and the inner wall of the cover unit 2. The liquor vapor rises along the flow channel to the steam outlet 3. As it rises along the water vapor separation device 4 in the steam outlet 3, it continuously impacts the baffle 43. Under the action of the vapor separator 4, a vapor vortex and centrifugal force are generated. The liquid medium in the liquor vapor is thrown onto the inner wall of the steam outlet 3 under the action of centrifugal force. The liquid medium slides down the inner wall of the steam outlet 3, while the liquor vapor continues to rise along the vapor separator 4. At this time, the liquor vapor after the liquid medium has been separated by the vapor separator 4 has a higher purity. The liquor vapor rises along the steam outlet 3 towards the temperature valve 34. The temperature sensing unit senses the temperature of the liquor vapor in the steam outlet 3. When the temperature of the liquor vapor reaches above 80°C, the temperature sensing unit sends an electrical sensing signal to the first control unit. After receiving the signal, the first control unit continues to transmit the converted signal to the temperature valve 34. Valve 34, the temperature valve 34, opens after receiving a signal, allowing the liquor vapor to continue rising along the steam delivery channel. Simultaneously, the pressure sensing unit senses the pressure of the liquor vapor inside the steam delivery port 3. When the pressure is greater than 0.7 MPa, it is considered high pressure, and the second control unit sends a signal to control the high pressure valve 35 to open and release pressure. When the pressure sensing unit senses that the pressure inside the steam delivery port 3 is greater than 0.1 MPa and less than 0.7 MPa, it is considered low pressure, and the second control unit sends a signal to control the low pressure valve 366 to open and release pressure. The liquor vapor enters the condenser 13 through the delivery pipe 16 for cooling and liquefaction, and finally enters the liquor receiving unit 15 to form liquor.
