[0005] A rotating motor has its rotating end extending through the cooking chamber into its interior. A rotating shaft is fixed to the rotating end of the motor. A support plate is fixedly connected to the end of the rotating shaft away from the motor. The sidewall of the support plate is rotatably and sealingly connected to the inner wall of the movable opening. Multiple placement components are arranged in a circular array around the rotating shaft on its sidewall. Each placement component is used to hold tuna pieces. The bottom of each placement component is fixedly connected to the rotating shaft, and one end of each placement component is fixedly connected to the support plate. Multiple openings are provided on the support plate corresponding to the placement components.
[0006] In some embodiments, multiple support columns are provided, and the tops of the multiple support columns are fixedly connected to the bottom of the cooking chamber.

[0008] In some embodiments, the bottom surface of the heating plate matches the shape of the top surface of the groove, and the bottom of the heating plate abuts against the top of the groove.
[0009] In some embodiments, the discharge pipe coincides with the axis of the cooking chamber.
[0010] In some embodiments, two spray heads are symmetrically arranged about the axis of the cooking chamber. The mounting ends of both spray heads are fixedly connected to the inner wall of the cooking chamber. Both spray heads are connected to the water inlet pipe and are inclined downwards.
[0011] In some embodiments, the filter plate is located on top of the two spray nozzles, the sidewall of the filter plate is fixedly connected to the inner wall of the cooking chamber, and the outer diameter of the filter plate matches the inner diameter of the cooking chamber.
[0012] In some embodiments, the rotating motor coincides with the transverse axis of the movable port.
[0013] In some embodiments, the placement component includes:
[0014] A connecting rod is provided, which is perpendicular to the rotating shaft, and one end of the connecting rod is fixedly connected to the side wall of the rotating shaft.
[0015] The placement frame has multiple first ventilation holes, the other end of the connecting rod is fixedly connected to the side wall of the placement frame, the placement frame is arranged parallel to the rotating shaft, one end of the placement frame has a placement opening, and the end of the placement frame near the placement opening is fixedly connected to the support plate.
[0016] A sliding plate is provided with multiple second ventilation holes. The outer diameter of the sliding plate matches the inner diameter of the placement frame. The bottom of the sliding plate is slidably connected to the bottom wall inside the placement frame. A baffle is fixedly connected to one end of the sliding plate.

[0018] Compared with existing technologies, the advantages of this invention are as follows: By driving a rotating shaft with a rotating motor, multiple placement components (placement frames) rotate within the steaming chamber, ensuring uniform heating of the tuna chunks during steaming and avoiding localized overheating or undercooking. Combined with the steam generated by the heating plate and spray nozzles, an all-around thermal circulation is formed, further improving the uniformity and efficiency of steaming. The design of the movable port and support plate allows for easy insertion and removal of the sliding plate containing the tuna chunks, simplifying the complex loading and unloading process in traditional steaming equipment. The coordinated design of the sliding plate and baffle (operated via a pull port) makes loading and unloading of tuna chunks more efficient, especially suitable for large-scale continuous production. The spray nozzle design not only assists in generating steam but also allows for water replenishment or cleaning during steaming, enhancing the equipment's versatility. The filter plate effectively filters impurities, ensuring a clean steaming environment while preventing direct contact between the tuna chunks and the spray nozzles, thus preventing physical damage. The inclusion of a pressure gauge and pressure relief valve allows for precise control of pressure and temperature within the cooking chamber, preventing cooking failures due to excessively high or low pressure. The control panel integrates control functions for the heating plate and rotating motor, offering simple operation and easy automation. The fitted design of the heating plate with the grooves reduces heat loss and improves thermal efficiency.
