[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] See also Figures 1-8 The present invention provides a technical solution: a beverage sterilizing device, comprising a high-temperature sterilizing section 1, a plurality of ultraviolet sterilizing sections 2 installed at the end of the high-temperature sterilizing section 1, a liquid inlet box 3 connected to the beverage passage inside the high-temperature sterilizing section 1 installed at the front end, and a liquid outlet box 4 connected to the beverage passage inside the ultraviolet sterilizing section 2 located at the very end. Beverages can enter the high-temperature sterilizing section 1 through the liquid inlet box 3 for high-temperature sterilization. After high-temperature sterilization, the beverages enter the ultraviolet sterilizing section 2 for ultraviolet sterilization, forming a synergistic sterilization effect, making the sterilization effect more thorough and expanding the sterilization spectrum.

[0028] The high-temperature sterilization part 1 includes a first cylinder 11, in which a plurality of heat exchange cylinders 12 capable of circulating beverages are fixedly arranged, and the two ends of the plurality of heat exchange cylinders 12 are respectively connected to the liquid inlet box 3 and the ultraviolet sterilization part 2, and an adjusting baffle 13 is slidingly arranged in the first cylinder 11, and a plurality of openings 131 are opened on the adjusting baffle 13, and the plurality of heat exchange cylinders 12 are placed in the plurality of openings 131. The side of the adjusting baffle 13 close to the liquid inlet box 3 is a heating zone 14, and the length of the heating zone 14 can be changed by changing the position of the adjusting baffle 13. The beverage in the heat exchange cylinder 12 can be heated by filling hot air into the first cylinder 11. Since the flow rate of the beverage is fixed when it flows in the heat exchange cylinder 12, the time the beverage is in the heating zone 14 can be changed by changing the length of the heating zone 14, thereby adjusting the heating time of the beverage, so as to facilitate the sterilization of beverages with different formulas and ensure that the nutrients in different beverages will not be destroyed due to too long heating time; the ultraviolet sterilization part 2 includes a second cylinder 21 and a spoiler box 22. The box 22 is installed at the front end of the second cylinder 21. A plurality of ultraviolet sterilization cylinders 23 capable of circulating beverages are fixedly arranged in the second cylinder 21. Before the beverage enters the ultraviolet sterilization cylinder 23, it will be disturbed by the flow disturbance box 22, which has a mixing effect, so that the substances in the beverage enter the ultraviolet sterilization cylinder 23 after being mixed. The ultraviolet sterilization cylinder 23 is made of a transparent material that allows ultraviolet light to pass through. A plurality of ultraviolet sterilization lamps 24 are arranged on the outside of the ultraviolet sterilization cylinder 23. When the beverage enters the ultraviolet sterilization cylinder 23, the ultraviolet light on the outside of the ultraviolet sterilization cylinder 23 is emitted. The ultraviolet light emitted by the external sterilization lamp 24 can pass through the ultraviolet sterilization cylinder 23 and irradiate the beverage to sterilize the beverage; the cross-sections of the heat exchange cylinder 12 and the ultraviolet sterilization cylinder 23 are both flat rectangles, which reduces the thickness of the beverage channel while ensuring the flow rate. When the beverage is in the heat exchange cylinder 12, the heating area increases, making the beverage easier to heat. When the beverage is in the ultraviolet sterilization cylinder 23, because the beverage is thin, the ultraviolet light can more easily irradiate the inside of the beverage, thereby improving the sterilization effect and ensuring the sterilization quality.

[0029] Furthermore, the ultraviolet sterilization tube 23 is wavy in shape composed of multiple arc segments 25, and multiple ultraviolet sterilization lamps 24 are respectively arranged on the inner side of each arc segment 25. The wavy ultraviolet sterilization tube 23 increases the length of the beverage channel, increases the time the beverage stays in the ultraviolet sterilization tube 23, and improves the sterilization effect. Setting the ultraviolet sterilization lamp 24 on the inner side of the arc segment 25 can efficiently utilize ultraviolet light.

[0030] Specifically, the spoiler box 22 includes a box body, in which a plurality of staggered spoilers 221 are fixedly arranged. The spoilers 221 can block the flowing beverage and achieve turbulent mixing of the beverage. Flow ports 222 are provided on both end surfaces of the box body for entering or discharging beverages.

[0031] Specifically, a plurality of hot air distribution holes 111 are provided on the two side walls of the first cylinder 11 that are perpendicular to the heat exchange cylinder 12. The plurality of hot air distribution holes 111 are connected to the heating zone 14. A hot air cover 15 that is buckled onto the outside of the plurality of hot air distribution holes 111 is fixedly provided on the upper and lower sides of the first cylinder 11. After the hot air pipe is connected to the hot air cover 15, hot air can be filled into the heating zone 14 through the hot air distribution holes 111 on one side, so that the hot air flows outside the heat exchange cylinder 12, thereby heating the heat exchange cylinder 12. The hot air after heat exchange is discharged through the hot air distribution holes 111 on the other side. The hot air can also flow evenly in the heating zone 14 through the hot air distribution holes 111.

[0032] Specifically, a plurality of cold air distribution holes 211 are provided on the two side walls of the second cylinder 21 perpendicular to the ultraviolet sterilization cylinder 23, and the plurality of cold air distribution holes 211 are connected to the interior of the second cylinder 21. Cold air covers 26 that are buckled on the outside of the plurality of cold air distribution holes 211 are fixedly provided on the upper and lower sides of the second cylinder 21. After the cold air pipe is connected to the cold air cover 26, cold air can be filled into the second cylinder 21 through the cold air distribution holes 211 on one side, so that the cold air flows outside the ultraviolet sterilization cylinder 23, thereby cooling the beverage flowing in the ultraviolet sterilization cylinder 23, preventing the temperature in the beverage from being heated for too long due to the inability to quickly reduce the temperature of the beverage. By cooling the beverage, the cooling speed of the beverage can be increased. At the same time, the ultraviolet sterilization lamp 24 is in the cooling gas, preventing the service life of the ultraviolet sterilization lamp 24 from being reduced due to excessive temperature. Finally, the cold air can be discharged through the cold air distribution holes 211 on the other side, and the cold air can be evenly flowed in the second cylinder 21 through the cold air distribution holes 211.

[0033] Specifically, a guide rod 16 is fixedly provided on the inner wall surface of one side of the first cylinder 11 that is horizontal to the heat exchange cylinder 12, and the adjusting baffle 13 is slidably installed on the guide rod 16. The guide rod 16 is used to limit the moving distance of the adjusting baffle 13 to prevent it from moving to the hot air distribution hole 111. A threaded rod 17 is also rotatably provided in the first cylinder 11, and the threaded rod 17 is threadedly connected to the adjusting baffle 13. A motor 18 is fixedly provided on the outside of the first cylinder 11, and one end of the threaded rod 17 is connected to the power output end of the motor 18. After starting the motor 18, the threaded rod 17 can be driven to rotate, and the axis of the adjusting baffle 13 is driven to move by the rotation of the threaded rod 17, thereby changing the position of the adjusting baffle 13.

[0034] The working principle and use process of the present invention are as follows: the beverage supply pipe is connected to the liquid inlet tank 3, the beverage discharge pipe is connected to the liquid outlet tank 4, the hot air supply pipe and the hot air discharge pipe are respectively connected to the hot air covers 15 on the upper and lower sides of the first cylinder 11, the cooling supply pipe and the cold air discharge pipe are respectively connected to the cold air covers 26 on the upper and lower sides of the second cylinder 21, and the ultraviolet sterilization lamp 24 and the motor 18 are connected to the power supply; when the beverage is sterilized, the beverage is transported by an external water pump, the beverage enters the heat exchange cylinder 12 through the liquid inlet tank 3, and the hot air is transported to the heating area 14 in the first cylinder 11 through the hot air supply pipe. When the beverage in the heat exchange cylinder 12 passes through the heating area 14, it will be heated to achieve high-temperature sterilization of the beverage. Then the beverage enters the spoiler box 22, passes through the spoiler plate 221 to turbulently mix the beverage, and then enters the ultraviolet sterilization cylinder 23, where the beverage is sterilized by the ultraviolet light emitted by the ultraviolet sterilization lamp 24. Cold air is injected into the second cylinder 21, and the beverage flowing inside is heat-exchanged through the ultraviolet sterilization cylinder 23 to cool the beverage, thereby preventing the beverage from being heated for too long due to the inability to quickly reduce the temperature inside the beverage. The beverage can be sterilized and cooled multiple times by the ultraviolet sterilization parts 2 at several locations, and finally the beverage is discharged through the liquid outlet box 4, completing the sterilization and cooling of the beverage; by arranging the ultraviolet sterilization lamp 24 in the second cylinder 21, overheating of the ultraviolet sterilization lamp 24 can be avoided, the service life is increased, and the space in the second cylinder 21 is reasonably utilized, reducing the overall size of the device; when it is necessary to change the heating time of the beverage, the motor 18 drives the threaded rod 17 to rotate to change the position of the adjustment baffle 13 in the first cylinder 11, and then change the length of the heating zone 14, so as to adjust the heating time of the beverage without affecting the flow rate of the beverage, and ensure that the nutrients in different beverages will not be destroyed due to excessive heating time.

[0035] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
