Description

Technical Field

[0001] This utility model relates to the field of steam sterilization equipment technology, and in particular to a high-efficiency sterilization equipment. Background Technology

[0002] In industries with extremely high hygiene requirements, such as medical, food, and pharmaceutical, sterilization equipment is a key facility for ensuring product quality and safety. Among them, high-temperature steam sterilization equipment is widely used for the sterilization of various items due to its advantages such as thorough sterilization and no residue. This type of equipment generates high-temperature, high-pressure steam, utilizing the penetrating power and high temperature characteristics of steam to kill microorganisms on the surface and inside of items, thereby achieving aseptic standards. Currently, traditional high-temperature steam sterilization equipment has a relatively simple steam supply design, typically delivering steam into the sterilization chamber through a single steam pipe or a few nozzles. This results in uneven steam distribution within the sterilization chamber. Some areas have sufficient steam, while corners or areas where items are piled up are difficult for steam to reach, creating sterilization dead zones. This prevents items from being fully and thoroughly sterilized, posing safety hazards. In terms of the efficiency of item placement and processing, traditional equipment typically uses fixed single-layer or a few-layer shelves, resulting in limited space for item placement, a small number of items that can be sterilized at one time, and low equipment utilization. Moreover, these shelves are mostly fixed inside the sterilization chamber and cannot be moved or rotated, keeping the items stationary throughout the sterilization process. This further exacerbates the problem of uneven steam contact and affects the sterilization effect. Utility Model Content

[0003] This invention solves the problems in related technologies and proposes a highly efficient sterilization device.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A high-efficiency sterilization device includes a sterilization cabinet, an inner sterilization shell installed in the sterilization cabinet, the inner sterilization shell being fixedly connected to the sterilization cabinet, an air supply rack inserted into the inner sterilization shell, the air supply rack being detachably fixedly connected to the inner sterilization shell, a high-temperature steam generator cooperating with the air supply rack installed in the inner sterilization shell, a sealing cover installed at the head of the inner sterilization shell, a multi-layer rack rotatably installed at the center of the lower end face of the sealing cover, and a drive motor for driving the multi-layer rack to rotate being fixedly installed on the upper end face of the sealing cover.

[0008] As a preferred embodiment, the head of the vertical shell is provided with a sealing block, which is integrally formed with the vertical shell, and an extension pressure plate is also fixedly installed on the inner side of the sealing block.

[0009] As a preferred embodiment, the multi-layer display rack includes a central rotating rod and display trays, wherein the display trays are evenly fitted onto the central rotating rod and are fixedly connected to the central rotating rod.

[0010] As a preferred embodiment, the sealing cover includes a round cover plate, a knob holder, and a retaining plate corresponding to the right-angle retaining groove. The round cover plate is pressed against the upper end face of the extended pressure plate, the knob holder is vertically fixed to the upper end face of the round cover plate, and the retaining plate is integrally formed and disposed on the outer side of the round cover plate.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application uses a drive motor to rotate the multi-layer rack, allowing items to be evenly contacted by high-temperature steam, avoiding sterilization dead zones. Simultaneously, the structural design of the gas supply rack ensures that steam is evenly distributed within the sterilization inner shell, further improving the sterilization effect and ensuring thorough sterilization of items. The gas supply rack and sterilization inner shell are detachably and fixedly connected, and the sealing cover achieves quick installation and removal through the cooperation of right-angle slots and plates, facilitating equipment maintenance and item loading and unloading, and improving work efficiency. The multi-layer rack design increases the storage space for items, allowing for the sterilization of more items at once, improving equipment utilization. The sealing design between the sealing cover, the gas supply rack, and the sterilization inner shell, as well as the sealing block and extended pressure plate at the vertical shell head, effectively prevent steam leakage, improve steam utilization, and reduce energy consumption.
