[0020] Example 2:

[0021] Please see Figures 1-4 This utility model discloses a sterilization device for food production, comprising a condenser tank 5 with three sets of heat exchange tubes 51 inside; the water inlet end of the heat exchange tubes 51 is fixedly connected to an electromagnetic pneumatic valve 52; the front side of the electromagnetic pneumatic valve 52 is fixedly connected to a preheating water tank 53; the front side of the preheating water tank 53 is fixedly connected to a water inlet pipe 54; a through hole is provided on the left side wall of the preheating water tank 53, and the preheating water tank 53 is fixedly connected to a temperature sensor 55 through the through hole; the water outlet at the top of the heat exchange tubes 51 is fixedly connected to a water outlet pipe 56; the left side of the water outlet pipe 56 is fixedly connected to the right side of a water pump 57; the left side of the water pump 57 is fixedly connected to the water filling point of a steam boiler 6; the valve body of the electromagnetic pneumatic valve 52 is covered with a heat insulation layer; the preheating water tank 53 is equipped with an electric heating tube, which provides a stable heat source in cooperation with the temperature sensor 55; the water outlets of the three sets of heat exchange tubes 51 are connected in series through the water outlet pipe 56.

[0022] The working principle of a sterilization device for food production based on the above embodiments is as follows: First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation. Secondly, this sterilization device generates high-temperature steam through a steam boiler 6, which is then transported to the guide ring 11 inside the sterilization tank 1 via a reversing valve 7. The steam, controlled by the reversing valve 7, can enter the guide ring 11 from two different directions. After passing through the slots 12 inside the guide ring 11, it drives the vortex blades 14 to rotate along the bearing 13, causing the spray pipe 15 to rotate synchronously. The spray holes 16 on the surface of the spray pipe 15 adopt a conical design with decreasing aperture to increase the water flow velocity and enhance the impact force. During rotation, high-temperature water or steam is sprayed... The spray is evenly sprayed into the inner cavity of the sterilization tank 1, covering the food surface and complex structural areas to avoid localized high temperatures. At this time, the rotation trajectory of the spray pipe 15 is constrained by the limiting ring 17 to ensure spray stability. During the sterilization process, the high-temperature steam that has been sterilized enters the condenser tank 5 through the exhaust pipe 4. Since the steam temperature in the condenser tank 5 is higher at the bottom than at the top, a stepped temperature difference is required for the cold water to be heated to maximize the heat conversion efficiency. Therefore, the external cold water inlet pipe 54 enters the preheating water tank 53. The temperature sensor 55 in the preheating water tank 53 first detects the temperature of the cold water to be heated in real time. The electric heating tube in the preheating water tank 53 raises the temperature of the cold water to be heated to a suitable temperature. By setting up three sets of preheating water tanks 53, the water flowing into the corresponding heat exchange tubes 51 is input with a gradient of equal temperature difference. After the cold water temperature reaches the expected value, the temperature sensor 55 sends a signal to the electromagnetic pneumatic valve 52 to open the valve and control the flow rate of the cold water to be heated. The cold water then heats the high-temperature steam in the condenser tank 5 through the three sets of heat exchange tubes 51. The heat exchange is achieved by setting three sets of independently circulating heat exchange tubes 51 at the middle and output ends of the steam flow. The segmented heat exchange causes the steam to cool down in stages, avoiding the phenomenon of reverse heating of the steam at the middle and output ends due to the internal temperature of the heat exchange tubes 51. The waste heat is recovered to preheat the cold water to be heated. The water after heat conversion is sent back to the steam boiler 6 by the water pump 57 for recycling, forming a closed-loop energy system. Through the synergistic effect of dynamic spraying, heat recovery and intelligent control, this device achieves dual optimization of efficient sterilization and energy utilization.

[0023] This invention provides an improved sterilization device for food production. The device uses a steam boiler 6 to generate high-temperature steam. A reversing valve 7 controls the steam to flow from two different directions through a guide ring 11, driving the vortex blades 14 to rotate. This rotates the spray pipes 15, which have tapered spray holes 16 on their surface, and under the constraint of a limiting ring 17, evenly sprays a high-temperature medium, achieving dynamic sterilization. After sterilization, the steam is introduced into a condenser 5. A preheating water tank 53 intelligently regulates the temperature of the cold water, utilizing a stepped temperature difference to allow the cold water to efficiently exchange heat with the steam through heat exchange pipes 51, recovering waste heat. The preheated water is then pumped back to the steam boiler 6 for circulation, forming a closed-loop energy-saving system.
