Description

Technical Field

[0001] This utility model relates to the field of high-temperature sterilization equipment technology, specifically a high-temperature sterilization equipment for pre-prepared food processing. Background Technology

[0002] Pre-prepared meals are semi-finished or finished foods made from various raw materials such as water and poultry, combined with various seasonings and auxiliary materials, and after a series of pre-selection and preparation processes, they are delivered to consumers. Due to their convenience, they are popular among some consumers. The production process of pre-prepared meals includes raw material processing, packaging, and storage. In order to ensure the safety of pre-prepared meals, sterilization treatment is required during processing.

[0003] Existing technologies, such as the high-temperature sterilization equipment for pre-prepared food processing disclosed in CN222340497U, complete the high-temperature sterilization of pre-prepared food through the cooperation of a high-temperature tank, a cooling component, a high-temperature sterilization component, and a moving frame. However, during the sterilization process, the pre-prepared food tends to accumulate together, making it impossible to sterilize it completely, thus affecting the sterilization effect and causing certain adverse effects on users. In order to overcome the shortcomings of existing technologies, we propose a high-temperature sterilization equipment for pre-prepared food processing. Utility Model Content

[0044] Bottom heat conduction cavity 2: fixed to the bottom of the high-temperature sterilization tank 1, connected to the side of the water tank 3, and connected to the inside of the tank through equidistant heat conduction pipes 14 on the top surface, so as to conduct the high-temperature steam generated by the water tank 3 to the sterilization tank and provide a heat transfer channel for the sterilization process.

[0045] Stirring drive motor 13: Fixed in the motor mounting frame 12 above the top cover plate 9, the output shaft vertically passes through the cover plate and is connected to the stirring rod 17 through a coupling to provide a power source for stirring;

[0046] Internal stirring rod 17: The surface of the stainless steel shaft is welded with spiral blades, and the bottom end of the rod is equipped with a bearing seat that is rotatably connected to the bottom of the tank to ensure stirring stability;

[0047] Bottom heating element 21: U-shaped tubular electric heating elements are evenly arranged at the bottom of the water tank 3, and the surface is covered with an insulating layer. They are connected to the power supply through the wiring terminals to realize heat energy conversion.

[0048] Heat pipe 14: It is vertically installed between the bottom heat conduction cavity 2 and the sterilization tank 1. The pipe wall is provided with heat dissipation fins, and the interior is hollow to form a steam channel. The top corresponds to the heat conduction pipe mounting hole 18 on the top of the tank.
