Technical Field

[0001] This utility model relates to the field of concentrated beverage production technology, specifically a beverage concentration device. Background Technology

[0002] Concentrated beverages are drinks made by removing water from fruits. They are usually used to make concentrated fruit juices. Because water is removed, concentrated beverages are usually more sugary and acidic, and have a richer taste, which makes them popular with some people. In the prior art, patent publication number CN218686366U discloses a concentrated evaporation device for concentrated juice, including a tank body, a tank cover at the upper end of the tank body, several support legs fixedly installed at the lower end of the tank body, a motor fixedly installed on the bottom surface of the tank body, a through hole opened on the bottom surface of the tank body, the output shaft of the motor body being rotatably connected to the inner wall of the through hole, a stirring rod provided inside the tank body, the lower end of the stirring rod being fixedly connected to the output shaft of the motor body, heating rods fixedly installed on both sides inside the tank body, a discharge pipe with a valve fixedly installed at the lower end of one side of the tank body, the discharge pipe communicating with the inside of the tank body, and a cooling device provided on the upper side of one side of the tank body; The above-mentioned concentration and evaporation equipment has some problems in actual use. For example, steam may come into contact with the upper tank wall and liquefy into water, flowing back into the concentrated juice, slowing down the concentration rate. The slowed concentration speed may cause the caramel produced during concentration to stick to the tank wall, resulting in a poor concentration effect. To address this, we propose a beverage concentration device. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6This embodiment provides a technical solution: a beverage concentration device, including a concentration tank 1, with a bracket fixedly connected to the lower side of the concentration tank 1. An inspection port is opened on the front side of the concentration tank 1, and a sealing plate is fixedly connected to the front side of the inspection port by bolts. A rubber sealing gasket is provided on the stepped surface of the rear side of the sealing plate, and the surface of the rubber sealing gasket contacts the interior of the inspection port to achieve a sealing function. A controller 12 is provided on the front side of the bracket, and the input terminal of the controller 12 is electrically connected to an external power source. The device also includes a drainage mechanism 2 and an anti-stick structure 4. A steam heating jacket 6 is provided on the inner wall of the concentration tank 1. The air inlet of the steam heating jacket 6 is connected to an external steam generator, and the water outlet of the steam heating jacket 6 is connected to an external sealed storage tank. The water tank and the concentration tank 1 are equipped with a pressure regulating pipe 7 on the front side. The front end of the pressure regulating pipe 7 is connected to an external negative pressure pump. The concentration tank 1 is equipped with a pressure regulating valve 8 on the upper side. The concentration tank 1 is equipped with a pressure gauge 9 on the right side (the pressure gauge 9 is a conventional negative pressure gauge, and the pressure information inside the concentration tank 1 can be judged in real time by visual observation). The measuring end of the pressure gauge 9 extends into the interior of the concentration tank 1. The input end of the pressure regulating valve 8 is electrically connected to the output end of the controller 12. The concentration tank 1 is equipped with an inlet pipe 10 on the upper right side and an outlet pipe 11 on the lower right side. The inlet pipe 10 and the outlet pipe 11 are connected to each other. Both the middle and middle sections of the concentration tank 1 are equipped with solenoid valves connected in series. The right end of the inlet pipe 10 is connected to an external liquid supply device, and the right end of the outlet pipe 11 is connected to an external collection device. The input ends of both solenoid valves are electrically connected to the output end of the controller 12. When the concentration device is needed, the external liquid supply device is adjusted to discharge a specified amount of unconcentrated beverage into the concentration tank 1 through the inlet pipe 10. Then, the external negative pressure pump can be adjusted to extract the gas inside the concentration tank 1, creating a negative pressure environment inside the concentration tank 1. At this time, the pressure inside the concentration tank 1 drops to about 0.02 MPa. The boiling point of the beverage is around 60℃. At this point, the external steam generator can be adjusted to discharge high-temperature steam into the steam heating jacket 6. The high-temperature steam then contacts the inner wall of the steam heating jacket 6, releases heat, and transforms into liquid water. The heat is dissipated into the interior of the concentration tank 1. The liquefied water is discharged into the external water storage tank through the outlet of the steam heating jacket 6. At this time, the temperature inside the concentration tank 1 gradually rises. When the temperature inside the concentration tank 1 exceeds 60℃, the unconcentrated beverage begins to boil, and the water in the unconcentrated beverage begins to vaporize and rise as steam. Drainage mechanism 2: Located on the upper side of the concentration tank 1, the drainage mechanism 2 includes a cover plate 21, inclined guide channels 22, drain outlets 23, a bottom temporary storage tank 24, and a distilled water outlet pipe 25. The cover plate 21 is fixedly connected to the upper end of the concentration tank 1. The inner arc surface of the cover plate 21 is fixedly connected with evenly distributed inclined guide channels 22. The lower side wall of the inclined guide channels 22 is provided with evenly distributed drain outlets 23. The lower side of the inner arc surface of the cover plate 21 is provided with a bottom temporary storage tank 24. The inside of the cover plate 21 is provided with a serpentine cooling coil 3. The inlet and outlet are connected to an external condensate circulation system. A distilled water outlet pipe 25 is provided on the right side of the inclined guide trough 22. The front of the distilled water outlet pipe 25 is connected to an external sealed water storage tank. The drainage mechanism 2 also includes a rotating rod 26, an inclined frame 27, and scrapers 28. The rotating rod 26 is rotatably connected to the middle of the upper side wall of the cover plate 21. The inclined frame 27 is fixedly connected to the outer arc surface of the rotating rod 26. Scrapers 28 are evenly distributed and fixedly connected to the outer surface of the inclined frame 27. All scrapers 28 extend to the inclined guide trough at the same height. Inside the cover plate 22, the lower end of the inclined frame 27 extends into the bottom temporary storage tank 24. A motor 5 is located on the top of the cover plate 21. The output shaft of the motor 5 is fixedly connected to the upper end of the rotating rod 26. The input end of the motor 5 is electrically connected to the output end of the controller 12. This allows for the control of the external condensate circulation equipment, continuously circulating the condensate inside the serpentine cooling coil 3 to reduce the surface temperature of the cover plate 21. At this time, steam contacts the inner arc surface of the cover plate 21, liquefies upon cooling, and this liquid flows into the inclined guide water tank 22, then along... As the water leaks downwards through the drain 23, the liquid water will eventually fall into the bottom temporary storage tank 24 and then flow into the external sealed water storage tank along the distilled water outlet pipe 25. During this period, the controller 12 needs to be adjusted and the motor 5 is turned on. The output shaft of the motor 5 rotates and drives the rotating rod 26 to rotate. During this period, the inclined frame 27 will rotate around the rotating rod 26. During this period, the scraper 28 will scrape off the water droplets adhering to the inner wall of the inclined guide water tank 22, so that the water droplets will quickly leak down through the drain 23, fall into the bottom temporary storage tank 24 and be discharged. Anti-sticking structure 4: It includes a rectangular fixed cylinder 41, a rectangular sliding cylinder 42, a height adjusting frame 43, and a scraper 44. The rectangular fixed cylinder 41 is fixedly connected to the upper side of the inside of the concentration tank 1. The rectangular sliding cylinder 42 is slidably connected inside the concentration tank 1. The height adjusting frame 43 is fixedly connected to the lower side of the rectangular sliding cylinder 42. The scraper 44 is fixedly connected to the outer surface of the height adjusting frame 43 and is evenly distributed. Nylon scraper blades are fixedly connected to the outer arc surface of the scraper 44. The anti-sticking structure 4 also includes an inclined groove 45, a rotating column 46, and a cylindrical slider 47. The rotating column 46 is rotatably connected to the inside of the rectangular sliding cylinder 42. The cylindrical slider 47 is fixedly connected to the outer arc surface of the rotating column 46. The inclined groove 45 is opened on the inner arc surface of the rectangular sliding cylinder 42. The inclined slide 45 is an inclined elliptical slide (the inner wall shape of which is consistent with the outer shape of the cylindrical slider 47). The outer arc surface of the cylindrical slider 47 is slidably connected to the inner arc surface of the inclined slide 45. The upper end of the rotating column 46 is fixedly connected to the lower end of the rotating rod 26. During the rotation of the rotating rod 26, the rotating column 46 will be driven to rotate, causing the cylindrical slider 47 to rotate around the central axis of the rotating column 46. During this period, the cylindrical slider 47 and the inclined slide 45 maintain a sliding connection. As the cylindrical slider 47 rotates around the central axis of the rotating column 46, it pulls the rectangular slide cylinder 42 up and down, causing the rectangular slide cylinder 42 to move back and forth up and down inside the rectangular fixed cylinder 41. During this process, the rectangular fixed cylinder 41 is moved upwards and downwards. The scraper moves up and down, causing the nylon scraper on the scraper 44 to scrape the inner wall of the concentration tank 1 repeatedly. This prevents the beverage from undergoing the Maillard reaction and producing caramel that adheres to the inner wall of the concentration tank 1. During the continuous boiling of the beverage, the water in the beverage is rapidly lost, and the remaining beverage is the concentrated beverage. At this time, the controller 12 can be adjusted, and the pressure regulating valve 8 will operate. The pressure regulating valve 8 restores the air pressure inside the concentration tank 1 to the normal atmospheric pressure standard. (The pressure regulating valve 8 is installed in series. It is installed on the pressure regulating pipe set on the front upper side of the concentration tank 1. During operation, the actual pressure is fed back in real time by the pressure sensor inside the pressure regulating valve 8. The pressure sensor here is bidirectionally electrically connected to the controller 12.) The strain gauge inside the device deforms under stress, causing a change in its resistance. The controller 12 detects this resistance information to obtain pressure information. After comparing the set value, the controller 12 drives the electric actuator to precisely adjust the valve core opening to control the flow rate. By adjusting the linkage mechanism between the spring tension and the valve position, the air pressure inside the concentration tank 1 is stabilized at about 0.02 MPa. When a normal pressure is required, the pressure regulating valve 8 can be fully opened to restore the air pressure inside the concentration tank 1. Then, the solenoid valve on the liquid outlet pipe 11 opens to discharge the concentrated beverage out of the equipment. (After a period of use, the sealing plate on the inspection port needs to be manually opened to manually clean the small amount of caramel adhering to the surface of the nylon scraper.)

[0016] The working principle of the beverage concentration equipment provided by this utility model is as follows: When the concentration equipment is needed, the external liquid supply device is adjusted to discharge a specified amount of unconcentrated beverage into the concentration tank 1 through the liquid inlet pipe 10. Then, the external negative pressure pump is adjusted to extract the gas inside the concentration tank 1, so that the inside of the concentration tank 1 is in a negative pressure environment. At this time, the pressure inside the concentration tank 1 drops to about 0.02 MPa, and the boiling point of the beverage is about 60℃. At this time, the external steam generator is adjusted to discharge high-temperature steam into the steam heating jacket 6. Then, the high-temperature steam contacts the inner wall of the steam heating jacket 6, releases heat, and turns into liquid water. The heat is dissipated into the inside of the concentration tank 1, and the liquefied water flows along the steam heating jacket. The outlet of the jacket 6 drains into the external water storage tank. At this time, the temperature inside the concentration tank 1 gradually rises. When the temperature inside the concentration tank 1 exceeds 60℃, the unconcentrated beverage begins to boil, and the water in the unconcentrated beverage begins to vaporize, turning into steam that rises upwards. At this point, the external condensate circulation equipment can be adjusted to continuously circulate the condensate inside the serpentine cooling coil 3, thereby reducing the surface temperature of the cover plate 21. The steam then contacts the inner arc surface of the cover plate 21, liquefies upon cooling, and flows into the inclined guide water tank 22, then leaks downwards along the drain outlet 23. This liquid water eventually falls into the bottom temporary storage tank 24, and then flows into the external sealed water storage tank along the distilled water outlet pipe 25. During this period, it is necessary to... To control the controller 12, the motor 5 operates. The output shaft of the motor 5 rotates, causing the rotating rod 26 to rotate. During this time, the inclined frame 27 rotates around the rotating rod 26. Meanwhile, the scraper 28 scrapes away water droplets adhering to the inner wall of the inclined guide channel 22, allowing the water droplets to quickly drain down the drain outlet 23, fall into the bottom storage tank 24, and be discharged. During the rotation of the rotating rod 26, the rotating column 46 rotates, causing the cylindrical slider 47 to rotate around the central axis of the rotating column 46. During this time, the cylindrical slider 47 maintains a sliding connection with the inclined slide 45. As the cylindrical slider 47 rotates around the central axis of the rotating column 46, it pulls the rectangular slide cylinder 42 up and down, causing the rectangular slide cylinder 42 to move within the rectangular fixed cylinder 45. The device moves up and down repeatedly, causing the rectangular fixed cylinder 41 to move up and down repeatedly, which in turn causes the nylon scraper on the scraper 44 to scrape the inner wall of the concentration tank 1 repeatedly. This prevents the beverage from undergoing the Maillard reaction and producing caramel that sticks to the inner wall of the concentration tank 1. During the continuous boiling of the beverage, the water in the beverage is quickly lost, and the remaining beverage is the concentrated beverage. At this time, the controller 12 can be adjusted to operate the pressure regulating valve 8. During operation, the pressure sensor inside the pressure regulating valve 8 provides real-time feedback on the actual pressure. After comparing the actual pressure with the set value, the controller 12 drives the electric actuator to precisely adjust the valve core opening to control the flow rate. Through the linkage mechanism of adjusting the spring tension and the valve disc position, the gas pressure inside the concentration tank 1 is finally stabilized at 0.At approximately 0.02 MPa, when normal pressure is required, simply fully open the pressure regulating valve 8 to release the pressure inside the concentration tank 1. The pressure regulating valve 8 restores the pressure inside the concentration tank 1 to normal atmospheric pressure. Then, the solenoid valve on the outlet pipe 11 opens, discharging the concentrated beverage out of the equipment.

[0017] It is worth noting that the core chip of the controller 12 disclosed in the above embodiments is a single-chip microcomputer, specifically the S7-200. The motor 5, pressure regulating valve 8, and solenoid valve can be freely configured according to the actual application scenario. It is recommended that the motor 5 be an RF series vertical flange mounted helical gear reducer motor, the pressure regulating valve 8 be a ZDLP-16C model electric single-seat regulating valve, and the solenoid valve be a VFS5110-5EB-06 model metal-sealed solenoid valve. The controller 12 controls the operation of the motor 5, pressure regulating valve 8, and solenoid valve using methods commonly used in the prior art.
