In addition, the U-shaped connecting pipe 7 serves as a connecting bridge between the serpentine sterilization tube body 2 and the drying connection box body 12, so that the air flows from top to bottom first, and then from bottom to top. When the air moves from bottom to top, the gravity of water is used to separate the gas and liquid. The U-shaped connecting pipe 7 is not only cooled to liquefy the steam, but also bears the role of gas-liquid separation. Then, the sterilized air enters the interior of the drying connection box 12 through the first fixed pipe 13, and absorbs moisture in the air through the drying plate 14; then enters the interior of the filtering connection box 16 through the second fixed pipe 15, undergoes three-level filtration through the filter mesh layer 17, the activated carbon filter layer 18 and the HEPA filter layer 19, and is finally discharged through the air outlet installation box 20.
