Description

Technical Field

[0001] This application relates to the field of sterilization and filling equipment technology, specifically to a sterilization and filling equipment for dairy products. Background Technology

[0002] Dairy products refer to various foods made from cow's milk or sheep's milk and their processed products as the main raw materials, with or without the addition of appropriate amounts of vitamins, minerals and other auxiliary materials, and processed under the conditions required by laws, regulations and standards. They are also called cream products. In the production and processing of dairy products, filling equipment is required for filling.

[0003] An existing patent (publication number: CN221795165U) discloses a sterilization and filling equipment for dairy products, including a housing. A feed pipe is fixedly connected to the top of the housing, and a filling mechanism is fixedly installed inside the bottom of the housing. A heating and sterilization structure is located inside the housing, and a bearing is fixedly installed inside the top of the housing. This sterilization and filling equipment, through the heating and sterilization structure, activates a rotating motor. The motor drives a rotating shaft to rotate an arc-shaped heating rod (first and second), a heat-conducting pipe, and a telescopic scraping structure. Simultaneously, the arc-shaped heating rods are electrically heated. Then, through stirring, the heat from the arc-shaped heating rods and the heat-conducting pipe is transferred to the dairy products, thus sterilizing them. The sterilization speed is further accelerated by the irradiation of ultraviolet LED sterilization lamps.

[0004] The ultraviolet germicidal LED lamps in the aforementioned comparative documents have poor penetration ability in liquids. For thicker liquid layers, only the surface can be effectively sterilized, and the microorganisms in the deeper layers cannot be inactivated. In order to further optimize the sterilization effect of the device, a sterilization and filling equipment for dairy products is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a sterilization and filling equipment for dairy products, which enables dairy products to form a thin film, thus allowing for more concentrated and effective ultraviolet irradiation, resulting in shorter sterilization time and higher efficiency.

[0006] To achieve the above objectives, this application provides the following technical solution: a sterilization and filling equipment for dairy products, comprising a base, a high-temperature sterilization mechanism, a conveying device, and an ultraviolet sterilization mechanism. The high-temperature sterilization mechanism includes a sterilization tank fixedly connected to the upper surface of the base and a first servo motor installed at the top of the sterilization tank, as well as spiral blades fixedly connected to the output shaft end of the first servo motor. The inner wall of the sterilization tank is equipped with uniformly distributed electric heaters. The conveying device includes a liquid pump, a sterile pipe, and a fan.

[0007] The ultraviolet sterilization mechanism includes an outer shell and a quartz glass roller and a liquid outlet pipe disposed inside the outer shell. The liquid outlet pipe is fixedly connected to one side of the quartz glass roller. The quartz glass roller is rotatably fitted onto the inner wall of the outer shell through the liquid outlet pipe. The interior of the quartz glass roller is provided with a multi-hole atomizing nozzle, which is connected to the output end of a sterile tube. The inner wall of the outer shell is equipped with uniformly distributed ultraviolet lamp modules. A second servo motor is fixedly connected to one side of the outer shell. The output shaft end of the second servo motor and the outer surface of the liquid outlet pipe are both fixedly connected with sprockets. A chain is provided on the outside of the outer shell, and the two sprockets are connected by chain drive.

[0008] The above scheme allows for high-temperature rotary agitation sterilization of dairy products by setting up a high-temperature sterilization mechanism. After preliminary sterilization, the dairy products are conveyed to the ultraviolet sterilization mechanism via a conveying device. The products are then dispersed into a uniform liquid film through a multi-hole atomizing nozzle. This thin-film structure maximizes surface area exposure, which is beneficial for ultraviolet penetration and sterilization. Then, the ultraviolet lamp module and the second servo motor are activated. Since the multi-hole atomizing nozzle is located inside the quartz glass drum, the quartz glass drum rotates when the second servo motor is activated. The uniform rotation of the quartz glass drum ensures that each liquid film is evenly exposed to the irradiation of multiple ultraviolet lamp modules. The sterilization rate of the thin-film flow combined with ultraviolet light is much higher than that of static direct irradiation, achieving a higher quality sterilization process.

[0009] Furthermore, the liquid pump is installed in the liquid outlet at the bottom of the sterilization tank, one end of the sterile tube is connected to the output end of the liquid pump, and the outer surface of the sterile tube is fixedly connected to the inner wall of the outer shell.

[0010] Using the above method, starting the liquid pump can transport the dairy products that have undergone high-temperature sterilization in the sterilization tank to the porous atomizing nozzle through a sterile tube.

[0011] Furthermore, the fan is installed in the inner wall of the base, and the fan is located below the sterile tube.

[0012] The above solution allows for the appropriate cooling of dairy products transported in aseptic tubes by installing fans, creating suitable conditions for subsequent ultraviolet sterilization.

[0013] Furthermore, a first sealed bearing is fixedly connected to the outer surface of the sterile tube, and the outer surface of the first sealed bearing is fixedly connected to the inner wall of the quartz glass cylinder.

[0014] The above scheme, by setting the first sealed bearing, enables the quartz glass roller to rotate more stably outside the sterile tube.

[0015] Furthermore, a second sealed bearing is fixedly connected to the outer surface of the liquid outlet pipe, and the outer surface of the second sealed bearing is fixedly connected to the inner wall of the outer casing.

[0016] The above solution, by setting up an outlet pipe and a second sealed bearing, enables the quartz glass roller to rotate more stably inside the outer shell, allowing the film sprayed from the porous atomizing nozzle to continuously tumble on the inner wall of the quartz glass roller, exposing more surface area and avoiding sterilization blind spots caused by suspended particles blocking or insufficient local light.

[0017] Furthermore, a one-way valve is installed at the output end of the liquid outlet pipe.

[0018] The above solution enables one-way transport of sterilized dairy products by setting a one-way valve, facilitating the filling process.

[0019] Furthermore, the top of the sterilization tank is equipped with a liquid injection port, and the inner wall of the liquid injection port is threaded with a sealing plug.

[0020] The above solution allows for the convenient addition of dairy products requiring sterilization to the high-temperature sterilization unit by setting up an injection port, while ensuring a tight seal during sterilization.

[0021] Furthermore, support columns are fixedly connected to the four corners of the bottom surface of the base.

[0022] The above solution allows the device to be placed more stably on the contact surface by setting up support columns.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects: This sterilization and filling equipment for dairy products employs a high-temperature sterilization mechanism for high-temperature rotary stirring sterilization. After preliminary sterilization, the dairy products are conveyed to the ultraviolet sterilization mechanism via a conveying device. During this process, multi-hole atomizing nozzles disperse the dairy products into a uniform liquid film, increasing the surface area and facilitating ultraviolet penetration and sterilization. After activating the ultraviolet lamp module and the second servo motor, the multi-hole atomizing nozzles are located inside the quartz glass drum. The activation of the second servo motor drives the quartz glass drum to rotate at a uniform speed. This uniform rotation ensures that each liquid film is evenly exposed to the ultraviolet lamp module, thereby achieving efficient thin-layer flow ultraviolet sterilization. This sterilization method, combining thin-layer flow and ultraviolet irradiation, not only improves the sterilization rate but also ensures the sterilization quality. Attached Figure Description

[0026] In the picture: Detailed Implementation The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figure 1 and Figure 2 This embodiment of a dairy product sterilization and filling device includes a base 1, a high-temperature sterilization mechanism 2, a conveying device 3, and an ultraviolet sterilization mechanism 4. The high-temperature sterilization mechanism 2 includes a sterilization tank 201 fixedly connected to the upper surface of the base 1, a first servo motor 202 installed at the top of the sterilization tank 201, and a spiral blade 204 fixedly connected to the output shaft end of the first servo motor 202. The inner wall of the sterilization tank 201 is equipped with uniformly distributed electric heaters 203. By setting the electric heaters 203, the dairy products inside the sterilization tank 201 can be heated to achieve the effect of high-temperature sterilization. Simultaneously, the first servo motor 204 is activated. Machine 202 can drive electric heater 203 to stir the dairy products inside sterilization tank 201, so that the dairy product fluid forms a multi-layer mixture in sterilization tank 201, the heating is more uniform, and the effect of high temperature sterilization is optimized. The top of sterilization tank 201 is equipped with liquid injection port 205, and the inner wall of liquid injection port 205 is threaded with a sealing plug. By setting liquid injection port 205, it is convenient to add dairy products to be sterilized into high temperature sterilization mechanism 2, and the sealing is ensured during sterilization. Support columns 5 are fixedly connected to the four corners of the bottom surface of base 1. By setting support columns 5, the device can be placed more stably on the contact surface.

[0028] Please see Figure 2 , Figure 3 and Figure 4 The conveying device 3 includes a liquid pump 301, a sterile tube 302, and a fan 303. The ultraviolet sterilization mechanism 4 includes a housing 401 and a quartz glass roller 402 and a liquid outlet pipe 403 disposed inside the housing 401. The liquid outlet pipe 403 is fixedly connected to one side of the quartz glass roller 402. The quartz glass roller 402 is rotatably sleeved on the inner wall of the housing 401 through the liquid outlet pipe 403. The interior of the quartz glass roller 402 is provided with a multi-hole atomizing nozzle 404, which is connected to the output end of the sterile tube 302. When the liquid pump 301 is started, the dairy products that have undergone high-temperature sterilization inside the sterilization tank 201 can be conveyed to the multi-hole atomizing nozzle 404 through the sterile tube 302. In the multi-hole atomizing nozzle 404, the dairy product can be dispersed into a uniform film and sprayed onto the inner wall of the quartz glass drum 402. The outer surface of the liquid outlet pipe 403 is fixedly connected to a second sealing bearing 406, and the outer surface of the second sealing bearing 406 is fixedly connected to the inner wall of the outer shell 401. By setting the liquid outlet pipe 403 and the second sealing bearing 406, the quartz glass drum 402 can rotate more stably inside the outer shell 401. When convenient, the film sprayed by the multi-hole atomizing nozzle 404 continuously flips on the inner wall of the quartz glass drum 402, exposing more surface area and avoiding sterilization blind spots caused by suspended particles or insufficient local light.

[0029] Please see Figure 2 , Figure 3 and Figure 4 The inner wall of the outer casing 401 is equipped with uniformly distributed ultraviolet lamp modules 407. The ultraviolet lamp modules 407 use 200-280 nm UVC lamps and 190-220 nm UV lamps. The combination of nm deep ultraviolet LEDs provides supplementary sterilization for heat-resistant spores and bacterial spores that were not completely killed by high-temperature sterilization. A second servo motor 408 is fixedly connected to one side of the outer shell 401. Sprockets 409 are fixedly connected to the output shaft end of the second servo motor 408 and the outer surface of the liquid outlet pipe 403. A chain 410 is provided on the outside of the outer shell 401. The two sprockets 409 are connected by the chain 410. When the second servo motor 408 is started, it will drive the corresponding sprocket 409 to rotate. The chain 410 can make the other sprocket 409 rotate, which can make the liquid outlet pipe 403 rotate. When the liquid outlet pipe 403 rotates, the quartz glass roller 402 will rotate together. A one-way valve 411 is installed at the output end of the liquid outlet pipe 403. By setting the one-way valve 411, the sterilized dairy products can be transported in one direction, which facilitates the filling process.

[0030] Please see Figure 1 , Figure 2 and Figure 3A liquid pump 301 is installed in the liquid outlet at the bottom of the sterilization tank 201. One end of the sterile tube 302 is connected to the output end of the liquid pump 301. The outer surface of the sterile tube 302 is fixedly connected to the inner wall of the outer shell 401. Starting the liquid pump 301 can transport the dairy products that have undergone high-temperature sterilization in the sterilization tank 201 through the sterile tube 302 to the multi-hole atomizing nozzle 404. The fan 303 is installed in the inner wall of the base 1 and is located below the sterile tube 302. By setting the fan 303, the dairy products transported in the sterile tube 302 can be cooled appropriately, creating suitable conditions for the subsequent ultraviolet sterilization mechanism 4. A first sealed bearing 405 is fixedly connected to the outer surface of the sterile tube 302. The outer surface of the first sealed bearing 405 is fixedly connected to the inner wall of the quartz glass roller 402. By setting the first sealed bearing 405, the quartz glass roller 402 can rotate more stably outside the sterile tube 302.

[0031] It should be noted that by using the liquid pump 301 and the porous atomizing nozzle 404 together, dairy products can be dispersed into a uniform film, maximizing the surface area of ​​the liquid. The film thickness is usually controlled within 0.05-0.2 mm of the effective penetration depth of ultraviolet light, thus ensuring that ultraviolet light can completely cover every layer of fluid. The dairy products flow on the inner wall of the quartz glass drum 402, causing the film to continuously rotate and expose more surface area, avoiding sterilization blind spots caused by suspended particles or insufficient local light. In the film state, ultraviolet irradiation is more concentrated and effective, with shorter sterilization time and higher efficiency. Even high-viscosity dairy products, such as cream or fermented milk, can receive sufficient ultraviolet irradiation after being sprayed into a film, expanding the applicability of the device.

[0032] In this embodiment, a sterilization and filling equipment for dairy products can perform high-temperature rotary agitation sterilization of dairy products by setting a high-temperature sterilization mechanism 2. The dairy products that have undergone preliminary sterilization can be transported to the ultraviolet sterilization mechanism 4 through the conveying device 3, and dispersed into a uniform liquid film through the porous atomizing nozzle 404. This thin film structure maximizes the surface area exposure, which is conducive to ultraviolet penetration and sterilization. Then, the ultraviolet lamp module 407 and the second servo motor 408 are started. Since the porous atomizing nozzle 404 is located inside the quartz glass roller 402, the second servo motor 408 will cause the quartz glass roller 402 to rotate when it is started. The uniform rotation of the quartz glass roller 402 can make each layer of liquid film evenly exposed to the irradiation of multiple ultraviolet lamp modules 407. The sterilization rate of thin-layer flow combined with ultraviolet light is much higher than that of static direct irradiation, achieving a higher quality sterilization work.

[0033] The working principle of the above embodiment is as follows: First, the electric heater 203 is turned on to preheat the inside of the sterilization tank 201. Then, the dairy products to be sterilized are added to the sterilization tank 201 through the liquid inlet 205, and the heating temperature of the electric heater 203 is increased. At the same time, the first servo motor 202 is started. When the first servo motor 202 is started, it can drive the spiral blade 204 to rotate. The rotation of the spiral blade 204 can agitate the dairy products inside the sterilization tank 201, so that the dairy products can be heated more evenly, which is convenient for high-temperature sterilization. After high-temperature sterilization, the liquid pump 301 and the blower 303 can be started. When the liquid pump 301 is started, the dairy products in the sterilization tank 201 can be transported to the multi-hole atomizing nozzle 404 through the aseptic tube 302. The dairy products are sprayed in the form of a thin film onto the inner wall of the quartz glass roller 402 through the multi-hole atomizing nozzle 404. The start of the blower 303 can appropriately agitate the dairy products transported in the aseptic tube 302. Cooling facilitates the sterilization of dairy products in the ultraviolet sterilization unit 4. Then, the ultraviolet lamp module 407 and the second servo motor 408 are activated. When the ultraviolet lamp module 407 is activated, it irradiates and sterilizes the dairy products in the quartz glass drum 402. The activation of the second servo motor 408 causes the corresponding sprocket 409 to rotate. The chain 410 drives the sprocket 409 on the surface of the liquid outlet pipe 403 to rotate, which in turn causes the quartz glass drum 402 to rotate. When the quartz glass drum 402 rotates, each layer of liquid film is evenly exposed to the irradiation of multiple ultraviolet lamp modules 407, and the film continuously flips, exposing more surface area and improving sterilization quality. Finally, the sterilized dairy products are connected to external aseptic equipment for filling via the liquid outlet pipe 403 and the one-way valve 411. It should be noted that the one-way valve 411 is normally closed.
