Embodiment 1

[0024] See also figure 1 with figure 2 , the embodiment of the present invention provides a sterilization system applied to a freeze-drying cabinet, including a controller 1, a hydrogen peroxide device 3 and a pure steam device 4 respectively connected to the freeze-drying cabinet 2. The hydrogen peroxide device 3 is connected to the freeze-drying cabinet 2 through the first steam inlet pipe 5 , and the pure steam device 4 is connected to the freeze-drying cabinet 2 through the second steam inlet pipe 6 . The freeze-drying cabinet 2 is also provided with an exhaust pipe 7 connected to the first steam inlet pipe 5 and a drain pipe 8 connected to the second steam inlet pipe 6 . A first control valve 9 is installed on the first steam inlet pipe 5, a second control valve 10 is installed on the second steam inlet pipe 6, a third control valve 11 is installed on the exhaust pipe 7, and a first control valve 11 is installed on the drain pipe 8. Four control valves 12 . The hydrog...

Embodiment 2

[0032] In the present embodiment, except the concentration of the hydrogen peroxide gas delivered by the hydrogen peroxide device 3, the pressure in the freeze-drying cabinet 2 during the delivery of the hydrogen peroxide gas, the temperature of the steam delivered by the pure steam device 4 and the process of delivering the pure steam Except that the pressure in the middle freeze-drying cabinet 2 is different, others are all the same as in Example 1.

[0033] In this embodiment, the hydrogen peroxide gas delivered by the hydrogen peroxide device 3 has a concentration of 300 ppm. The temperature of the steam delivered by the pure steam device 4 is 130°C.

[0034] In this embodiment, the pressure in the freeze-drying cabinet 2 is maintained at 7.5 Pa during the process of transporting the hydrogen peroxide gas. During the process of transporting pure steam, keep the pressure in the freeze-drying cabinet 2 at 0.15 MPa.

Embodiment 3

[0036] In this embodiment, except that the concentration of the hydrogen peroxide gas delivered by the hydrogen peroxide device 3 and the temperature of the steam delivered by the pure steam device 4 are different, everything else is the same as that of the embodiment 1.

[0037] In this embodiment, the hydrogen peroxide gas delivered by the hydrogen peroxide device 3 has a concentration of 400 ppm. The temperature of the steam delivered by the pure steam device 4 is 145°C.

[0038] In this embodiment, during the process of transporting the hydrogen peroxide gas, the pressure in the freeze-drying cabinet 2 is kept at 10 Pa. During the process of transporting pure steam, keep the pressure in the freeze-drying cabinet 2 at 0.2 MPa.

Abstract

The invention discloses a sterilization system applied to a freeze-drying cabinet and a sterilization method of the sterilization system. The sterilization system comprises a controller, a hydrogen peroxide device and a pure steam device, wherein the hydrogen peroxide device and the pure steam device are connected with the freeze-drying cabinet, the hydrogen peroxide device is connected with the freeze-drying cabinet through a first steam inlet pipe, the pure steam device is connected with the freeze-drying cabinet through a second steam input pipe, and the freeze-drying cabinet is provided with an exhaust pipe and a drain pipe; a first control valve is mounted on the first steam inlet pipe, a second control valve is mounted on the second inlet pipe, a third control valve is mounted on theexhaust pipe, a fourth control valve is mounted on the drain pipe, and the hydrogen peroxide device, the pure steam device, the first control valve, the second control valve, the third control valveand the fourth control valve are connected with the controller. The sterilization effect of the freeze-drying cabinet is improved, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of freeze-drying cabinets, in particular to a sterilization system applied to a freeze-drying cabinet and a sterilization method thereof. Background technique [0002] Freeze-drying cabinets are widely used in bioengineering, pharmaceutical industry, food industry and other fields. Freeze-drying cabinets need to be sterilized. At present, the online sterilization methods of freeze-drying cabinets include steam sterilization, ethylene oxide sterilization, and vaporization process. methods such as hydrogen peroxide sterilization. Steam sterilization is widely used without pollution, but the pressure difference of this method changes greatly, which may cause leakage or corrosion, and the sterilization cycle is long; the ethylene oxide used for ethylene oxide sterilization is flammable and flammable. Explosive toxic substances have certain safety hazards and the sterilization cycle is long; vaporized hydrogen p...
