Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] See also Figure 1-3 , the utility model provides a technical solution for a sterilization device for milk production:

[0015] A sterilization device for milk production includes a tank body 1, comprising an inner layer 1.1 and an outer layer 1.2; an electromagnetic heating coil 2 is disposed between the inner layer 1.1 and the outer layer 1.2; and a liquid inlet pipe 3, an exhaust pipe 4, a first water immersion sensor 5, a temperature sensor 6, and a mixer 7 are disposed at the top of the tank body 1. A sanitary pump 8 is mounted on the liquid inlet pipe 3, and a safety valve 9 is mounted on the exhaust pipe 4, enhancing the safety of the heating process of the tank body 1. The mixer 7 has a stirring rod 7.1 positioned within the bottom of the tank body 1, and is affixed with multiple S-shaped stirring blades 7.2. The mixer 7 stirs clockwise, causing the milk in the tank body 1 to diffuse and flow from the center to the edge, making the milk easier to stir and evenly heated. A second water immersion sensor 10 is provided at the bottom of the tank body 1, a liquid outlet pipe 11 is provided at the bottom of the tank body 1, and a solenoid valve 12 is installed on the liquid outlet pipe 11. The electromagnetic heating coil 2, the first water immersion sensor 5, the temperature sensor 6, the mixer 7, the sanitary pump 8, the second water immersion sensor 10 and the solenoid valve 12 are respectively electrically connected to the PLC control module 13 through lines.

[0016] The device is basically in a sealed state as a whole, which avoids manual milk addition and reduces the entry of foreign matter. It can realize the automatic work process of adding milk, heating, stirring and releasing milk, and improves production efficiency.

[0017] The working principle is as follows: the safety pump 8 delivers the milk into the tank body 1 through the liquid inlet pipe 3. As the liquid level inside the tank body 1 rises, when the first water immersion sensor 5 contacts the milk, it will send the detected electrical signal to the PLC control module 13. The PLC control module 13 controls the sanitary pump 8 to stop working, the PLC control module 13 controls the electromagnetic heating coil 2 to start heating, and the PLC control module 13 controls the blender 7 to start stirring. During the stirring process, the milk in the middle of the tank body 1 will diffuse and flow from the center to the edge under the action of the stirring blades 7.2. At the same time, the milk at the bottom of the tank body 1 replenishes the milk lost in the middle of the tank body 1, achieving The milk is heated evenly in the circulation flow. When the temperature of the milk reaches the specified temperature, the temperature sensor 6 sends the detected electrical signal to the PLC control module 13. The PLC control module 13 controls the mixer 7 to turn off and stop the electromagnetic heating coil 2 from continuing to heat. At the same time, the PLC control module 13 controls the solenoid valve 12 on the liquid outlet pipe 11 to open, so that the sterilized milk flows out of the liquid outlet pipe 11 for collection. When the milk in the tank body 1 is exhausted, the second water immersion sensor 10, because it is not in contact with the milk, sends the detected electrical signal to the PLC control module 13. The PLC control module 13 controls the solenoid valve 12 to close.

[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
