Technical Field
[0001] This utility model relates to the field of milk storage technology, and in particular to a milk storage device with a sterilization mechanism. Background Technology
[0002] In traditional milk storage facilities, milk often lacks efficient sterilization before storage, making it easy for bacteria and other microorganisms to grow, affecting the milk's hygiene quality and shelf life. Furthermore, if milk remains stagnant for extended periods during storage, a film can easily form on its surface, affecting not only its appearance and taste but also potentially accelerating spoilage.
[0003] Therefore, a milk storage device with a sterilization mechanism is proposed to achieve efficient sterilization and stirring of milk, thereby ensuring the hygiene and safety of milk while effectively preventing milk curdling and improving the storage quality and food safety of milk. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a milk storage device with a sterilization mechanism.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A milk storage device with a sterilization mechanism includes a storage box, four connecting rods fixed to the upper end of the storage box, a sterilization box fixed to the upper end of the four connecting rods, an inlet pipe and an outlet pipe connected to the side wall of the sterilization box, a sterilization mechanism connected to the storage box inside the sterilization box, a stirring mechanism inside the storage box, and a discharge mechanism connected to the bottom of the storage box.
[0007] As a further improvement of this utility model, the sterilization mechanism includes a sterilization tube disposed inside the sterilization chamber. One end of the sterilization tube is connected to a feed pipe, and the other end of the sterilization tube is connected to a connecting pipe. The feed pipe passes through the top of the sterilization chamber and is fixedly connected to the sterilization chamber. The connecting pipe passes through the bottom of the sterilization chamber and the bottom of the storage box. The connecting pipe is fixedly connected to the sterilization chamber and the storage box. A first valve is provided on the connecting pipe.
[0008] As a further improvement of this utility model, the stirring mechanism includes a rotating rod that passes through the upper end of the storage tank. The rotating rod is rotatably connected to the storage tank. A motor is installed at the upper end of the storage tank. The output shaft of the motor is fixedly connected to the upper end of the rotating rod. A stirring rod is fixed on the side wall of the rotating rod.
[0009] As a further improvement of this utility model, the discharge mechanism includes a discharge pipe connected to the bottom of the storage box, a second valve on the discharge pipe, a fixing ring fixedly sleeved on the side wall of the discharge pipe, a cover below the discharge pipe, the cover and the fixing ring being hinged by a damping hinge, a lever fixed on the side wall of the cover, and an ultraviolet sterilization lamp provided at the inner bottom of the cover.
[0010] As a further improvement of this utility model, the sterilization tube has a spiral structure.
[0011] As a further improvement of this utility model, the bottom of the storage box is fixedly connected with four support columns.
[0012] The beneficial effects of this utility model are:
[0013] The sterilization mechanism allows milk to be sterilized before it enters the storage tank. The discharge mechanism closes the cover after the milk is discharged, and the discharge pipe is sterilized by ultraviolet sterilization lamps to prevent bacteria from growing in the discharge pipe.
[0014] By setting up a stirring mechanism, starting the motor drives the rotating rod to rotate, which in turn drives the stirring rod to rotate, thus stirring the milk and preventing the milk from forming a film due to prolonged stillness.
[0015] This invention ensures the sterility of milk before storage through a sterilization mechanism and uses ultraviolet light to sterilize the discharge pipe to prevent bacterial growth. At the same time, the stirring mechanism effectively prevents milk from standing still for a long time and forming a film, thus maintaining the quality of the milk. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figures 1-5 A milk storage device with a sterilization mechanism includes a storage tank 1. Four support columns 5 are fixedly connected to the bottom of the storage tank 1, and four connecting rods 2 are fixed to the upper end of the storage tank 1. The upper ends of the four connecting rods 2 are fixed to the same sterilization chamber 3. A water inlet pipe 4 and a water outlet pipe 7 are connected to the side wall of the sterilization chamber 3. The water inlet pipe 4 is connected to constant temperature hot water, which is introduced into the sterilization chamber 3 through the water inlet pipe 4. The hot water flows out through the water outlet pipe 7, thereby circulating constant temperature hot water inside the sterilization chamber 3. The water temperature is 72-75℃, and the time to pass through the sterilization pipe 20 is 15-30 seconds, achieving efficient sterilization through rapid heat exchange. The sterilization chamber 3 is equipped with a sterilization mechanism connected to the storage tank 1. The storage tank 1 is equipped with a stirring mechanism, and the bottom of the storage tank 1 is connected to a discharge mechanism.
[0024] In this invention, the sterilization mechanism includes a sterilization tube 20 disposed inside the sterilization chamber 3. The sterilization tube 20 has a spiral structure.

The feed pipe 6 passes through the top of the sterilization chamber 3 and is fixedly connected to the sterilization chamber 3. The connecting pipe 9 passes through the bottom of the sterilization chamber 3 and the bottom of the storage tank 1. The connecting pipe 9 is fixedly connected to the sterilization chamber 3 and the storage tank 1. A first valve 10 is provided on the connecting pipe 9. When milk is added to the storage tank 1, the first valve 10 is opened. After the milk filling is completed, the first valve 10 is closed.
[0025] The stirring mechanism includes a rotating rod 17 that runs through the upper end of the storage tank 1. The rotating rod 17 is rotatably connected to the storage tank 1. A motor 8 is installed at the upper end of the storage tank 1. The output shaft of the motor 8 is fixedly connected to the upper end of the rotating rod 17. A stirring rod 18 is fixed on the side wall of the rotating rod 17. By starting the motor 8, the rotating rod 17 is driven to rotate, which in turn drives the stirring rod 18 to rotate. The stirring rod 18 can stir the milk, which can prevent the milk from forming a film due to prolonged stillness.
[0026] The discharge mechanism includes a discharge pipe 11 connected to the bottom of the storage box 1. A second valve 12 is provided on the discharge pipe 11. A fixing ring 13 is fixedly sleeved on the side wall of the discharge pipe 11. A cover 15 is provided below the discharge pipe 11.

[0027] In use, constant-temperature hot water is introduced into the sterilization chamber 3 through the inlet pipe 4 and flows out through the outlet pipe 7, thus circulating constant-temperature hot water inside the sterilization chamber 3. Milk is added through the feed pipe 6, and is heated and sterilized as it flows through the sterilization pipe 20. The sterilized milk then enters the storage tank 1 for storage through the connecting pipe 9. During milk storage, the motor 8 can be started to drive the rotating rod 17 to rotate, which in turn drives the stirring rod 18 to rotate. The stirring rod 18 can stir the milk, preventing the milk from forming a film due to prolonged stillness. When milk needs to be discharged, the cover 15 is rotated open first, and then the second valve 12 is opened to discharge the milk. After the milk is discharged, the cover 15 is rotated closed, and the discharge pipe 11 is sterilized by the ultraviolet sterilization lamp 19 to prevent bacterial growth in the discharge pipe 11.
