[0017] The original high-temperature sterilization equipment is to load the packaged products into food trays and push them into the sterilization equipment for sterilization. During this process, the products need to be loaded onto trays and then the filled food trays are pushed into the sterilization equipment for sterilization. This requires a lot of manpower to load the products into food trays and then push the food trays into the sterilization equipment, which consumes manpower and requires a lot of space and time for loading and unloading trays.

[0018] like Figure 1-Figure 3 As shown, the present embodiment provides a vertical continuous sterilizer for soft-packaged food, including a plurality of vertical sterilization tanks 100, the vertical sterilization tanks 100 are hollow, and openings are provided at both upper and lower ends of the vertical sterilization tanks 100. Considering the automatic opening and closing of the openings of the vertical sterilization tanks 100, hydraulic door opening devices 140 are provided at the openings at the upper and lower ends of the vertical sterilization tanks 100. Considering the automatic transportation of food cans, a feeding device 130 is provided on one side of the top of the vertical sterilization tank 100. Considering the discharge of warm water in the vertical sterilization tank 100, a hot water tank 150 is provided on one side of the bottom of the vertical sterilization tank 100. Considering the cooling, transportation and packaging of food cans, a buffer cooling tank 110 is provided at the bottom of the vertical sterilization tank 100, and an underwater conveyor 120 is provided in the buffer cooling tank 110.

[0019] The improvement of this embodiment lies in that a feeding device 130 is arranged on one side of the vertical sterilization tank 100, and an underwater conveyor 120 is arranged in the buffer cooling tank 110. The feeding device 130 and the underwater conveyor 120 are used to realize automatic upper feeding, lower discharging and product in and out sterilization, without manual loading and pushing of the tray into the sterilization equipment, thus saving manpower and space.

[0020] Considering the introduction of sterilizing and cooling the food in the vertical sterilizing tank 100 and the introduction of the feeding device 130 and the hydraulic door opening device 140, the second embodiment of the utility model is shown.

[0021] One side of the top of the vertical sterilizing tank 100 is connected to an external steam device, one side of the bottom of the vertical sterilizing tank 100 is connected to a hot water tank 150, and the other side of the bottom of the vertical sterilizing tank 100 is connected to a cold water device. The control system controls the steam device to inject high-temperature steam into the vertical sterilizing tank 100. While the high-temperature steam is injected, the warm water in the vertical sterilizing tank 100 is discharged to the hot water tank 150 due to the pressure. When the high-temperature sterilization process of the food tank is completed, the control system controls the cold water device to inject cooling water from the bottom of the vertical sterilizing tank 100 to cool the food tank. The feeding device 130 includes a conveyor belt 130 for conveying food. 1. A blocking member 132 is provided on one side of the opening at the top of each vertical sterilizing tank 100. The blocking member 132 changes the conveying direction of food on the conveyor belt 131 so that the food is conveyed into the vertical sterilizing tank 100. At the same time, after the vertical sterilizing tank 100 is filled with food cans, the blocking member 132 is controlled by the system to rotate so that the food cans on the conveyor belt 131 are not blocked and are conveyed to the next vertical sterilizing tank 100. The hydraulic door opening device 140 includes a cover plate 141 for closing the opening and a hydraulic rod 142 for driving the cover plate 141 to move. The cover plate 141 is moved by the hydraulic movement of the hydraulic rod 142, thereby closing the opening.

[0022] In summary, the working principle of this solution is as follows:

[0023] After the vertical sterilizing tank 100 is filled with water having a temperature equal to the initial temperature of the food cans, the conveyor belt 131 delivers the food cans into the vertical sterilizing tank 100 from the inlet at the top of the vertical sterilizing tank 100, and the warm water acts as a buffer to prevent damage to the food cans; when the food cans are full of the vertical sterilizing tank 100, the top inlet is closed by the hydraulic rod 142 of the hydraulic door opening device 140, and the sterilization process begins. The system begins to inject steam from the top. Since the steam has pressure, the warm water in the vertical sterilizing tank 100 can be discharged into the hot water tank 150, and the steam puts the food cans in high temperature to achieve a sterilization effect; when the high-temperature sterilization process of the food cans is completed, cooling water is injected from the bottom of the vertical sterilizing tank 100, and the temperature of the food cans decreases accordingly, and the pressure cooling process is entered; when the temperature of the food cans decreases to the set value, the cooling process is completed, and the hydraulic rod 142 of the hydraulic door opening device 140 is opened. 42, so that the outlet at the bottom of the vertical sterilization tank 100 is opened, and the cooled food cans slowly fall due to the effect of gravity and the resistance of warm water, and scatter onto the underwater conveyor 120 of the buffer cooling tank 110, while the cooling water in the vertical sterilization tank 100 will not fall due to the vacuum effect. At the same time, the duration and temperature of this process are uniformly controlled by the control center; after the food cans in the vertical sterilization tank 100 are emptied, the system will automatically control the hydraulic door opening device 140 on the top, remove the cover plate 141 from the opening on the top of the vertical sterilization tank 100, reload the food cans and circulate back and forth. The sequential circulation of multiple vertical sterilization tanks 100 will realize a continuous sterilization process, and the underwater conveyor 120 can receive food cans of any size. During the entire travel process of the food cans until they reach the outlet, the underwater conveyor 120 is always in underwater operation, thereby ensuring that the food cans will not be contaminated.
