[0033] It can be understood that aseptic tank 1 is a kind of container for storing and processing material under aseptic condition, in the application scenario of the embodiment, aseptic tank 1 is used to buffer the dairy product supplied by feed valve group 2 after sterilization treatment.
[0034] The sterile tank 1 is provided with a containing cavity for containing dairy products, and the feeding port and the discharging port are communicated with the containing cavity, the discharging port can be arranged at the lowest end of the sterile tank 1, and the feeding port can be arranged at the side of the discharging port.
[0035] The dairy product feeding system provided by the utility model can be set to the first feeding state in the initial feeding stage, so that the feeding of the sterile tank 1 through the first feeding valve F1 and the stable feeding of the filling machine 5 through the second feeding valve F2 are realized, after the set liquid level in the sterile tank 1 is reached, the dairy product feeding system can be set to the second feeding state, the feeding of the sterile tank 1 through the first feeding valve F1 by the feeding valve group 2, and the feeding of the filling machine 5 by the sterile tank 1 along the second pipeline 20, and when the feeding valve group 2 stops feeding, the dairy product feeding system can also work in the third feeding state, so that the stable feeding of the filling machine 5 through the sterile tank 1 is realized, and the three feeding states can all avoid the foam in the sterile tank 1.
[0036] As can be seen, the utility model realizes the purpose of starting the filling machine 5 when there is no liquid level in the sterile tank 1, reduces the feeding waiting time, improves the equipment operation efficiency, ensures the stability of the feeding flow, effectively avoids the foam in the sterile tank 1 during the feeding process, and is beneficial to ensuring the stable filling work of the filling machine 5.
[0037] In some embodiments, as shown in Figure 1 The sterile tank 1 also has a ventilation interface, the ventilation interface is communicated with the compressed gas source 4 through the third pipeline 30, and the compressed gas source 4 is used for inputting sterile compressed gas into the sterile tank 1 through the third pipeline 30.
[0038] It can be understood that the containing cavity of the sterile tank 1 is communicated with the ventilation interface, and the ventilation interface can be arranged at the top end of the sterile tank 1. The compressed gas source 4 can be a gas source device capable of providing sterile compressed air or compressed nitrogen.
[0039] When the dairy product feeding system works in the second feeding state or the third feeding state and based on the feeding of the sterile tank 1 to the filling machine 5, the compressed gas source 4 inputs sterile compressed gas into the sterile tank 1 through the third pipeline 30, the sterile compressed gas drives the dairy products in the sterile tank 1 to be output from the discharging port, and then reaches the filling machine 5 through the second feeding valve F2, so as to meet the filling work requirements of the filling machine 5.
[0040] In some embodiments, as shown in Figure 1As shown, the second feed valve F2 is a two-position three-way solenoid directional valve, and has a first switching state and a second switching state; when the second feed valve F2 is in the first switching state, the feed valve group 2 and the filling machine 5 are connected; when the second feed valve F2 is in the second switching state, the discharge port and the filling machine 5 are connected.
[0041] Understandably, the second feed valve F2 has a first port, a second port and a third port. The first port is connected to the feed valve group 2, the second port is connected to the discharge port of the aseptic tank 1, and the third port is connected to the filling machine 5.

The feeding valve group 2 feeds the aseptic tank 1 through the first feeding valve F1, and the second feeding valve F2 is in the first switching state, that is, the first port and the third port of the second feeding valve F2 are connected, so that the feeding valve group 2 feeds the filling machine 5 through the second feeding valve F2.
[0043] After the set liquid level is reached in the sterile tank 1, the first feed valve F1 can be used to control the first pipeline 10 between the feed valve group 2 and the sterile tank 1 to be open or closed, depending on whether the feed side of the feed valve group 2 is stopped. The second feed valve F2 is in the second switching state, that is, the second port and the third port of the second feed valve F2 are connected, so that the sterile tank 1 can supply material to the filling machine 5 through the second feed valve F2.

This design can form a steam barrier between the second valve K2 and the third valve K3 to prevent the dairy product from flowing between the first valve K1 and the fourth valve K4, and at this time, the cleaning operation can be performed on the feeding device 6.

When the ultra-high-temperature sterilization machine is feeding, the feeding pipeline is open, and the return pipeline is closed; when the ultra-high-temperature sterilization machine is cleaned, both the feeding pipeline and the return pipeline are open to form a closed cleaning loop of the ultra-high-temperature sterilization machine and the first valve K1.
