Technical Field

[0001] This utility model relates to the field of camel milk powder processing technology, specifically to a preheating and sterilization device for camel milk powder processing. Background Technology

[0002] Currently, common dairy product preheating and sterilization equipment typically employs an integrated heating structure, which involves heating the entire tank uniformly by installing heating pipes or steam jackets at the bottom or outer wall of the tank. This heating design is prone to causing significant temperature differences between the top and bottom of the tank when processing highly viscous or heat-sensitive emulsions like camel milk. Especially when the liquid is not fully flowing, the upper part of the tank often heats up more slowly, while the lower part is prone to overheating. This results in uneven heating of some camel milk, incomplete sterilization, and even quality problems such as protein denaturation or charring.

[0003] Therefore, there is an urgent need for a preheating and sterilization device for camel milk powder processing to solve the above-mentioned technical defects. Utility Model Content

[0015] Please see Figure 1-4 This utility model provides an embodiment of a preheating and sterilization device for camel milk powder processing, comprising a heating and sterilization tank 1, a stirring assembly at the top of the heating and sterilization tank 1, a heating assembly at the lower inner wall periphery of the heating and sterilization tank 1, and a steam assembly on the left side of the heating and sterilization tank 1; the stirring assembly includes a stirring shaft 12 fixedly and rotatably connected to the center of the heating and sterilization tank 1, a drive motor 6 fixedly connected to the top of the heating and sterilization tank 1, a drive gear 5 fixedly connected to the output shaft of the drive motor 6, a driven gear 4 meshing with the bottom end of the drive gear 5, the bottom end of the driven gear 4 being fixedly sleeved with the stirring shaft 12, and a gearbox 3 installed outside the drive gear 5 and the driven gear 4; the heating assembly includes a heating cavity 11 surrounding the inside of the heating and sterilization tank 1, and distributed electric heating tubes 8 welded inside the heating cavity 11; Specifically, such as Figure 1 and Figure 4 As shown, hot water in the water tank 17 is drawn by the water pump 18 and introduced into different areas of the heating chamber 11 through two sets of water pipes 19 to achieve circulating heating. Electric heating tubes 8 are evenly arranged inside the heating chamber 11. The electric heating tubes 8 are installed in sections at the top, middle and bottom of the heating chamber 11 to heat the camel milk liquid at different heights. A temperature sensor 9 is installed near each set of electric heating tubes 8 to monitor the liquid temperature in real time. The PLC controller 10 receives the temperature signals from each set of temperature sensors 9 and performs segmented temperature control according to the set temperature zone to ensure that the entire tank of camel milk liquid is heated evenly and to avoid incomplete sterilization caused by temperature differences between the top and bottom, thereby ensuring a stable sterilization effect before subsequent spray drying.

[0016] The heating element 8 is assembled in sections on the upper, middle and lower inner walls of the heating chamber 11, and a set of temperature sensors 9 are installed on the side wall at the location of each section of the heating element 8. Furthermore, each section of heating element 8 is powered independently, and the corresponding temperature sensor 9 monitors the liquid temperature of that section in real time.

[0017] A scraper 13 is fixedly connected to the left side of the stirring shaft 12. The side wall of the scraper 13 is processed with high-temperature resistant silicone, and the silicone side is attached to the inner wall of the heating sterilization tank 1. Specifically, such as Figure 1 and Figure 2 As shown, the drive motor 6 is fixedly installed on the top of the heating sterilization tank 1. The output shaft of the drive motor 6 is connected to the drive gear 5, which drives the driven gear 4 to rotate through gear meshing. The driven gear 4 is fixedly sleeved with the stirring shaft 12 to form a stable transmission structure. The stirring shaft 12 is arranged vertically along the center of the heating sterilization tank 1, and a scraper 13 is fixedly connected to its left side. The scraper 13 is arranged in close contact with the inner wall of the heating chamber 11. The side wall is covered with a high-temperature resistant silicone layer, which can gently scrape the inner wall during the stirring process to prevent the camel milk from adhering to or sintering on the tank wall at high temperature, thereby improving the uniformity of stirring and the efficiency of heating, and ensuring the continuity and cleanliness of the sterilization process.

[0018] A water tank 17 is provided at the bottom of the heating sterilization tank 1, and a water pump 18 is installed at the top of the water tank 17. The output end of the water pump 18 is connected to two sets of water pipes 19 through a diversion valve, and each set of water pipes 19 is connected to the heating chamber 11. Specifically, such as Figure 1 and Figure 3 As shown, the hot water stored in the water tank 17 is pressurized and output by the water pump 18, and then introduced into two sets of water pipes 19 through the diversion control valve. The water pipes 19 are arranged around the heating chamber 11, and the hot water forms a circular circulation path in the heating chamber 11, which not only improves the heat transfer efficiency, but also facilitates temperature difference control of different heating areas. Combined with the segmented heating electric heating tube 8 and the multi-point temperature sensor 9, the camel milk liquid can be heated evenly in a stable water bath environment.

[0019] A steam generator 20 is installed on the left side of the heating and sterilization tank 1. The output end of the steam generator 20 is connected to a booster pump 21. The output end of the booster pump 21 is connected to a steam nozzle 22 through a pipe. The steam nozzle 22 is fixedly installed on the upper left side of the inner wall of the heating and sterilization tank 1. An air valve 2 is installed on the top left side of the heating and sterilization tank 1. An inlet 7 is installed on the upper front wall of the heating and sterilization tank 1. A PLC controller 10 is installed on the right side wall of the heating and sterilization tank 1. An outlet 14 is opened at the bottom of the heating and sterilization tank 1. A material pipe 16 is fixedly connected to the bottom of the outlet 14. A flow valve 15 is installed at the material pipe 16. Furthermore, a gas valve 2 is installed on the top left side of the heating sterilization tank 1 to regulate the pressure inside the tank, ensuring gas balance and preventing overpressure during high-temperature sterilization; a feed inlet 7 is provided on the upper front wall of the tank to facilitate the injection of camel milk; a PLC controller 10 is installed on the right side wall, integrating various sensor data inputs and actuator outputs to achieve intelligent control of components such as the electric heating tube 8, steam nozzle 22, and stirring shaft 12; a discharge port 14 is opened at the bottom of the tank for discharging the camel milk after sterilization; a feed pipe 16 is connected below the discharge port 14, and a flow valve 15 is provided on it to precisely control the discharge speed and batch.

[0020] Working Principle: The operator injects the camel milk liquid to be processed into the heating and sterilization tank 1 through the feed inlet 7, and then starts the PLC controller 10. The system begins to run according to the set program. In the preheating stage, water in the water tank 17 is pressurized by the water pump 18 and sent into two sets of water pipes 19. The hot water enters the heating chamber 11 to form a circular circulation path, which makes the wall of the heating chamber 11 heat up rapidly. At this time, the segmented electric heating tubes 8 heat in segments according to the instructions of the PLC controller 10. The heating intensity is dynamically adjusted according to the temperature signal fed back by the temperature sensors 9 of each segment, forming precise temperature control in the upper, middle and lower areas. The heat is conducted to the inside of the tank through the heating chamber 11, so that the camel milk liquid gradually heats up to the set preheating temperature range. During the heating process, the drive motor 6 drives the active gear 5 to rotate, which meshes with the driven gear 4 to make the stirring shaft 12 rotate. The stirring shaft 12 rotates at high speed along the center of the tank, driving the scraper 13 to scrape lightly on the inner wall. The high-temperature resistant silicone covering the outside of the scraper 13 adheres to the inner wall of the tank, which can effectively prevent Camel milk liquid coagulates or adheres at high temperatures, which simultaneously improves heat transfer efficiency, ensuring uniform heating of the liquid throughout the tank and preventing localized overheating or undercooling. Once the camel milk liquid reaches the set preheating temperature, the PLC controller 10 controls the steam generator 20 to start operating. The steam generator 20 heats the water and converts it into high-temperature steam, which is then pressurized by the booster pump 21 and atomized and sprayed out through the steam nozzles 22. The steam nozzles 22 are located on the upper left inner wall of the heating and sterilization tank 1, enabling the high-temperature steam to be evenly sprayed onto the surface of the camel milk liquid and the space above it, achieving rapid high-temperature sterilization. Throughout the process, the gas valve 2 adjusts the pressure inside the tank in real time to prevent excessive steam from causing overpressure and ensure safe operation of the equipment. After sterilization, the PLC controller 10 shuts down the heating and steam modules and opens the flow valve 15 below the bottom outlet 14, allowing the preheated and sterilized camel milk liquid to be orderly discharged through the feed pipe 16, facilitating connection to the next step of spray drying or packaging, thus achieving continuous and standardized camel milk powder production.
