A hydraulic cylinder is provided at the rear side of the sterilizer body, and the hydraulic rod of the hydraulic cylinder extends into the sterilizer body and is connected to a push plate. The push plate is directly opposite the rear side of the metal mesh box.

[0004] Regarding the aforementioned technologies, the applicant believes that in existing sterilization tanks, all the food packets to be sterilized are piled up inside the metal mesh box, and the food packets are squeezed against each other. The steam is not effective in sterilizing the food packets squeezed to the innermost part. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a high-temperature sterilization autoclave for prepared meal kits.

[0006] The high-temperature sterilization autoclave for ready-to-eat meals provided in this application adopts the following technical solution: A high-temperature sterilization autoclave for prepared meals includes a pot body with an open end and a lid for sealing the opening. A steam pipe is installed inside the pot body for spraying steam into the interior. A guide rail is fixed to the bottom of the pot body, and a metal mesh box is slidably mounted on the guide rail. The metal mesh box comprises several parallel rectangular boxes and a frame connecting the boxes. Several steam holes are provided around the sides and bottom of each box. Prepared meals to be sterilized are placed vertically inside the corresponding boxes. The frame is fitted onto the upper side wall of the boxes. A sterilization trough is reserved between adjacent boxes. Several sterilization tubes extending into the sterilization trough are fixed to the steam pipe.

[0007] Furthermore, the box is provided with several vertical partition nets, which are inclined along the length of the box and divide the interior of the box into multiple independent placement cavities.

[0008] Furthermore, a sliding groove is provided on the upper end face of the frame, and a connecting ear is fixed on the box body, which is engaged in the sliding groove and facilitates the adjustment of the distance between two adjacent boxes. The frame body is also provided with a locking assembly to prevent the box body from detaching from the frame body.

[0009] Furthermore, the locking assembly includes a pressure rod slidably disposed on the frame and used to press the connecting ear, a drive bar perpendicular to the pressure rod is fixed on the pressure rod, a drive groove is formed on the drive bar along the length direction, a screw is threadedly connected to the frame, and a drive block for pressing the drive plate is fixed at the end of the screw.

[0010] Furthermore, the upper end face of the guide rail is provided with a track groove along the length direction, and rollers that are rolled and disposed in the track groove are fixed at the bottom of the box on both sides.

[0011] Furthermore, an elastic fixing member is provided on the side of the pot body away from the lid. The elastic fixing member includes a spring fixed to the rear wall of the pot body. The free end of the spring is provided with an abutment plate, which abuts against the side wall of the metal mesh box away from the lid.

[0012] Furthermore, the pot lid has an annular sealing groove on the side facing the pot body, and an inflatable silicone rubber sealing ring is provided in the annular sealing groove. An inflation valve communicating with the inflatable silicone rubber sealing ring is provided on the outside of the pot lid.

[0013] In summary, this application includes at least one of the following beneficial technical effects: The metal mesh cage features a multi-cell independent design with pre-drilled sterilization tanks between adjacent cells. The sterilization pipes on the steam pipes extend directly into these tanks, allowing steam to be sprayed directly from the sides of the meal packs. Simultaneously, steam holes are located around the sides and bottom of the cage, enabling steam to penetrate from multiple directions—top, bottom, and sides—in conjunction with the vertically placed meal packs. Compared to traditional stacking methods, the increased contact area between steam and each meal pack effectively solves the problem of incomplete sterilization of the internal meal packs, reducing the microbial residue rate significantly.
