Description

Technical Field

[0001] The utility model relates to the field of sterile tanks, in particular to a high-sealing stainless steel sterile tank. Background Art

[0002] Sterile tanks are widely used in multiple fields such as medical and health, food processing, laboratories, etc. A sterile tank is a container used to store and transport sterile items. It is usually made of high-quality stainless steel or other materials that are resistant to high temperatures and corrosion to ensure that the internal environment always remains sterile. In the medical and health field, sterile tanks are used to store and transport sensitive drugs such as blood, vaccines, and antibiotics to ensure the effectiveness of these drugs during transportation and storage. In the food processing field, sterile tanks are used to store and transport various food raw materials and semi-finished products to ensure the freshness and taste of the food. In the laboratory field, sterile tanks are used to store and transport microbial samples to ensure the accuracy of experimental results.

[0003] During the use of a sterile tank, high-temperature and high-pressure conditions are used to achieve aseptic operation. In a sterile tank, through heating and pressurization, the air and microorganisms inside the container are killed, thus achieving an aseptic effect. The high-temperature and high-pressure conditions can effectively destroy the cell walls and membrane structures of microorganisms, making them lose the ability to grow and reproduce, thereby achieving the purpose of sterility. Secondly, the sterile tank ensures the effect of aseptic operation through a sealed method. In a sterile tank, sealing is a very important link. Only by ensuring good sealing performance of the sterile tank can the intrusion of external air and microorganisms be effectively prevented, ensuring that the substances inside the container are in a sterile state. Therefore, the sealing performance of the sterile tank is crucial for aseptic operation.

[0004] After searching the prior art, most sterile tanks adopt a single-layer structure. Secondly, the sterile tank ensures the effect of aseptic operation through a sealed method. In a sterile tank, due to the easy leakage of air at the internal discharge port and feed port of the single-layer sterile tank, a good sealing effect cannot be achieved, resulting in the inability of the sterile tank to achieve an aseptic effect. Moreover, in a single-layer sterile tank, due to the relatively thin tank wall, the heat preservation performance of the sterile tank is poor. Therefore, the following utility model patent is proposed. Summary of the Utility Model
