An electric exhaust valve 18 and a reverse air inlet hood 19 are also arranged on the heat storage tank 3. A heat release blower 20 is arranged on the reverse air inlet hood 19. The heat release blower 20 and the electric exhaust valve 18 are both electrically connected to the PLC controller 4;

[0021] Both the outer sides of the above-mentioned sterilization box 2 and the heat storage tank 3 are coated with a heat insulation material layer to reduce the heat exchange between the sterilization box 2 and the heat storage tank 3 and the outside world. The heat insulation material layer is a polyurethane foam layer or an aerogel felt layer.

[0022] A branch pipe 21 is also connected to the air duct 16. An electric valve 22 electrically connected to the PLC controller is provided on the branch pipe 21. The branch pipe 21 extends into the preheating chamber 5 and the outlet of the branch pipe 21 is located outside the preheating chamber 5. The part of the branch pipe 21 located inside the preheating chamber 5 is also of a serpentine coil structure and is arranged at intervals in layers with the discharge pipe 9. A plurality of air flow conversion mechanisms are evenly distributed in the branch pipe 21; the air flow conversion mechanism includes an inner pipe 23 coaxially arranged in the branch pipe 21. One end of the inner pipe 23 facing the incoming air direction is open and the other end is closed. A gas guide cone 24 is coaxially arranged at the closed end.

The inner pipe 23 is fixedly arranged on the inner wall of the branch pipe 21 through a column 26.

[0023] The working principle of this embodiment is as follows:

[0024] The beverage to be sterilized is fed from the raw material tank 1 into the discharge pipe 9 and then sequentially passes through the preheating chamber 5, the heating chamber 6 and the cooling chamber 7 in the sterilization box 2. The beverage is preheated by the heat-conducting liquid in the preheating chamber 5, enters the heating chamber 6 after preheating and is then heated to the rated sterilization temperature by the induction heating coil. The beverage after reaching the rated sterilization temperature flows in the sterilization section 11 for a rated time, such as 10 s - 20 s, to complete sterilization. The PLC controller 4 monitors the temperature of the sterilization section 11 through the electrically connected temperature sensor 12. After sterilization, the beverage enters the cooling chamber 7 for cooling in preparation for filling. The beverage exchanges indirect heat with the air flow in the cooling chamber 7. The temperature of the beverage decreases and the temperature of the air flow increases. The beverage after the temperature is reduced is sent to the filling line, and the heated air flow enters the heat storage tank 3 to release heat to the heat storage bricks 17 and then is discharged from the electric exhaust valve 18;

[0025] When the heat storage tank 3 needs to release heat, the electric exhaust valve 18 is closed, the electric valve 22 on the branch pipe 21 is opened, the blower 20 for heat release is turned on, and the air flow blows against the heat storage bricks 17 in the reverse direction to take away the heat. The heated air flow and the hot air flow sent out from the cooling chamber 7 enter the branch pipe 21 together. The branch pipe 21 releases heat to the heat-conducting liquid in the preheating chamber 5 to realize the utilization of the heat of the heat storage tank 3; it should be particularly noted that the application of the air flow conversion mechanism improves the heat exchange efficiency between the air flow and the branch pipe 21. Specifically, the air flow flows in the branch pipe 21. When passing through the inner pipe 23, the air flow can be forced to blow against the inner wall of the branch pipe 21, avoiding the stable flow of the air flow in the branch pipe 21. Stable flow easily causes the air flow in the central part of the air flow column not to participate in the heat exchange with the branch pipe 21 and directly blow out of the branch pipe 21. Therefore, compared with the prior art, the linkage heat exchange efficiency between the heat storage tank 3 and the preheating chamber 5 in this embodiment is higher;

[0026] In this embodiment, the application of the heat storage tank 3 can store part of the heat of the beverage when the temperature drops after sterilization. When the electricity price is high during the day, the heat storage tank 3 can be controlled to release heat into the preheating chamber 5 of the sterilization tank 2 to increase the preheating temperature of the beverage, thereby reducing the power consumption of the induction heating coil in the downstream heating chamber 6. When the electricity price is low at night, the daily operation mode can be restored, and the induction heating coil is used for heating while the heat storage tank 3 starts to store heat. This embodiment is novel in design, stable and safe in operation, which can not only reduce the production cost of enterprises, but also save energy and reduce pollution, and has strong practicability.

[0027] The embodiments of the present invention are given for purposes of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention so as to design various embodiments with various modifications suitable for specific purposes.
