[0020] The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments of the specification. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. In the following description, reference is made to "some embodiments", which describes a subset of all possible embodiments, but it should be understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

[0021] Example 1

[0022] Combined with reference to Figures 1 to 3 The present invention provides an automatic continuous sterilizer, comprising a sterilizing barrel 1, a sterilizing tank 2, and a storage barrel 3. A feed port 4 is provided at the top of the sterilizing barrel 1. A heating pipe 5 and a temperature sensor 11 are located within the sterilizing barrel 1. A solenoid valve 6 is located at the bottom of the sterilizing barrel 1. The solenoid valve 6 is connected to a first discharge pipe 16, which is connected to the sterilizing tank 2. An ultraviolet sterilization lamp 7 is located within the sterilizing tank 2. The outlet of the sterilizing tank 2 is connected to a second discharge pipe 17, which is connected to the storage barrel 3. Beverage enters the sterilizing barrel 1 through the feed port 4. The heating pipe 5 heats the beverage. The temperature sensor 11 ensures that the beverage is at the appropriate temperature, ensuring both sterilization and a pleasant taste. After maintaining the sterilization temperature for a certain period of time, the solenoid valve 6 is opened, allowing the beverage to flow through the sterilizing tank 2, undergo a secondary sterilization process under the irradiation of the ultraviolet sterilization lamp 7, and finally flow into the storage barrel 3 through the second discharge pipe 17.

[0023] Preferably, an isolation plate 15 is provided in the sterilization tank 2. The isolation plate 15 divides the sterilization tank 2 into an installation chamber 18 and a circulation chamber 19. The ultraviolet sterilization lamp 7 is installed in the installation chamber 18. The beverage flows through the circulation chamber 19 and is sterilized by the ultraviolet sterilization lamp 7. The isolation plate 15 does not hinder the passage of light from the ultraviolet sterilization lamp 7. The inlet of the circulation chamber 19 is connected to the first discharge pipe 16, and the outlet of the circulation chamber 19 is connected to the second discharge pipe 17. The sterilization tank 2 is divided into two parts by the isolation plate 15. The ultraviolet sterilization lamp 7 is installed in the installation chamber 18, which is convenient for installation and subsequent maintenance. Due to the function of the isolation plate 15, the circulation chamber below is not contaminated. At the same time, the isolation plate is made of a transparent material that can well allow ultraviolet rays to penetrate for sterilization. It is preferably made of quartz glass, which basically does not weaken the sterilization effect of the ultraviolet sterilization lamp 7.

[0024] Preferably, the ultraviolet sterilization lamps 7 are arranged in multiple rows in the installation chamber 18, so that the beverage can be fully irradiated by the ultraviolet sterilization lamps 7 while flowing through the circulation chamber 19. The ultraviolet sterilization lamps 7 are arranged and installed throughout the installation chamber 18 to ensure that the beverage can be continuously irradiated and sterilized while flowing through the circulation chamber 19, thereby ensuring the sterilization effect of the ultraviolet sterilization lamps.

[0025] Preferably, a flow controller 12 is provided at the inlet of the flow chamber 19 to control the flow rate of the beverage in the flow chamber 19. The flow controller 12 allows the beverage to flow through the flow chamber 19 at a slower speed, thereby controlling the flow rate. Less beverage flows through the flow chamber 19 at the same time, reducing the depth of the beverage and ensuring the effect of ultraviolet sterilization.

[0026] Preferably, a rotating shaft 8 is provided in the sterilizing barrel 1, and a stirring rod 9 is connected to the rotating shaft 8. By stirring the beverage in the sterilizing barrel 1, the beverage can be heated evenly, and the sterilization effect will not be achieved due to insufficient temperature in some areas, nor will the taste of the beverage be affected due to excessive temperature in some areas.

[0027] Preferably, the barrel wall of the sterilizing barrel 1 is covered with an insulation layer 10. Covering the insulation layer 10 can avoid heat dissipation and save energy during the heating and subsequent insulation stages of the beverage.

[0028] Preferably, the heating tubes 5 are multiple, and the heating tubes 5 are arranged and distributed along the inner side of the barrel wall of the sterilizing barrel 1. The heating tubes 5 in the sterilizing barrel 1 are multiple, which can increase the temperature of the beverage faster and save time.

[0029] Preferably, a cooling pipe 14 is provided in the storage barrel 3, and the cooling pipe 14 is connected to the cooling device 13. After being cooled by the cooling device 13, the cold water passes through the cooling pipe 14 to cool the beverage in the storage barrel 3. Cooling the sterilized beverage can prevent the beverage from being affected by excessively high temperature for too long and at the same time, the beverage can be stored for a longer period of time after cooling.

[0030] Example 2

[0031] See attached Figure 3 This embodiment differs from the first embodiment in that a concave mirror 20 is provided within the installation chamber 18, and the ultraviolet sterilization lamp 7 is mounted below the reflective surface of the concave mirror 20. The ultraviolet light emitted by the ultraviolet sterilization lamp 7 is reflected from both sides and directed toward the flow chamber 19 below. The concave mirror 20 allows the ultraviolet light emitted by the ultraviolet sterilization lamp 7 to be directed toward the beverage below as much as possible, thereby enhancing the ultraviolet sterilization effect and ensuring that the beverage flowing through is evenly sterilized by the ultraviolet light.

[0032] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. The scope of protection of the present utility model should be based on the scope of protection of the claims.
