Working Principles of Dry Heat Sterilization Cabinet
1. The dry heat sterilization box adopts the dry heat sterilization method, which refers to the method of sterilization using high-temperature dry hot air. This method applies to the sterilization of high-temperature-resistant glass and metal products, as well as oils and fats that do not allow the penetration of humid and hot gases (such as oil-based ointment mechanisms, injection oils, etc.), and high-temperature-resistant powdered chemical drugs. It is suitable for high-temperature-resistant glassware, porcelain, glassy syringes, etc., but not for the sterilization of rubber, plastics, or most drugs.
2. In dry and hot conditions, due to the poor heat penetration and strong heat resistance of microorganisms, they must be exposed to high temperatures for a long time to achieve sterilization. Therefore, the temperature used for dry hot air sterilization is generally higher than that for wet-hot sterilization. To ensure sterilization effectiveness, it is generally stipulated that sterilization should be carried out at 135–140 degrees Celsius for 3-5 hours; sterilization at 160–170 degrees Celsius for 2-4 hours; and sterilization at 180–200 degrees Celsius for 0.5–1 hour can kill all microorganisms, including spores.

Mechanical System Structure and Performance Characteristics
Sealing Door
| No. | Contents | Parameter Description |
| 1 | Material Quality | The door panel is made of 316L stainless steel material, and the reinforcing ribs are made of Q235B material. |
| 2 | Door Components | After welding, the door components are subjected to vibration stress relief treatment to eliminate welding stress, effectively improving the structural stability and performance of the door components. |
| 3 | Opening and Closing Doors | Adopting pneumatic lifting technology, the equipment is designed to be maintenance-free within its lifespan.
Simple and easy to use, it greatly reduces the labor intensity of operators opening and closing doors. |
| 4 | Sealing Ring | The newly customized high-quality and tear-resistant silicone rubber material mushroom-shaped double-layer door sealing ring has a better sealing effect and longer service life. Due to the good adhesion between this sealing ring and the side wall of the sealing groove, it ensures a sterilization effect. The sealing ring can withstand a temperature of 300 ℃. |

Safety Interlocking |
When the door does not enter the main triangle position, the door cannot be lifted or lowered. |
| The program can only be started when the door is lowered to its normal sealed position and sealed properly. | ||
| The sealing door cannot be started without closing the program; Once the program starts and runs, the sealed door is locked and cannot be opened, ensuring safe operation. | ||
| Double-hinged motorized door with locking device, double door interlocking. | ||
| Equipped with a door switch memory system, it is used when the front and rear doors are in different purification areas, and sterilization is not completed, so the doors on the low-level purification area side cannot be opened. |
