Description
Technical field
It the utility model is related to freeze dryer field, more particularly to a kind of freeze dryer with hydrogen peroxide sterilization.
Background technology
In production fields such as biological products, blood product, medicines, to ensure such as protein, micro- of the main component in product
Biology etc. is not denatured or lost biologos, keeps original character, generally most of product need to be freeze-dried
Processing.Before freezing every time, freeze drying box, cooling cylinder and the pipeline of freeze dryer are required to be rinsed with high temperature injection with water, to ensure to freeze
The cleaning of the casing and pipeline of dry machine.After the completion of on-line cleaning, the sterilizing that carried out disinfection to the casing and pipeline of freeze dryer is also needed, really
Protect the cleaning of equipment, pipeline.
Now in production fields such as biological products, blood product, medicines, freeze dryer typically using pure steam on-line cleaning and
It is online to sterilize, cooled after the completion of sterilization using the natural type of cooling, because body of freeze dryer and pipeline have heat-insulation layer, led
Temperature fall time length is caused, influences the arrangement of production；And general body of freeze dryer and pipeline are non-pressure equipment, the steam pressure being passed through
Can not be too big so that the sterilization of body of freeze dryer and pipeline is not thorough.
Utility model content
In view of the above-mentioned problems, the utility model purpose is to provide a kind of freeze dryer with hydrogen peroxide sterilization, passed through
Oxidation hydrogen (VHP) carries out disinfection sterilizing to body of freeze dryer and pipeline, to solve the problems of the prior art.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of freeze dryer with hydrogen peroxide sterilization, including freeze dryer, vaporized hydrogen peroxide sterilizer, the gasification peroxide
Change hydrogen sterilizer gas outlet to connect by the freeze drying box of admission line and freeze dryer, the condenser of freeze dryer by discharge duct with
Exhaust fan is connected, and control valve is equipped with the admission line, discharge duct.
A kind of preferred scheme of the present utility model, high efficiency particulate air filter is equipped with the admission line, discharge duct.
Another preferred scheme of the present utility model, the air inlet of the vaporized hydrogen peroxide sterilizer are provided with rotary-type remove
Wet machine.
Another preferred scheme of the present utility model, set between high efficiency particulate air filter and exhaust fan on the discharge duct
There is catalyst decomposer.
Another preferred scheme of the present utility model, the control valve on the admission line, discharge duct is manual ball
Valve.
Freeze dryer of the utility model with hydrogen peroxide sterilization, peroxide is produced by vaporized hydrogen peroxide (VHP) sterilizer
Change hydrogen, hydrogen peroxide gas is passed through the freeze drying box of freeze dryer, condenser carries out disinfection to the casing and pipeline of freeze dryer
Sterilize, the gas after sterilization is discharged through discharge duct, shortens the sterilization cycle.Vaporized hydrogen peroxide (VHP) is one
Kind of strong oxidizer, the oxygen molecule (ecological oxygen) of release can penetrate and destroy the cell membrane and cell membrane of microorganism, into intracellular
Portion, the enzyme system of microorganism is aoxidized, hinder the basic metabolic function of bacterium (enzyme) or influence their membrane configuration
So as to cause cell death.Destruction to all the components in microbial cell is all irreversible, ensure that the thorough of sterilization
Property.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order that technological means of the present utility model and implementation are apparent to, it is further with reference to specific embodiment
Illustrate the utility model.
Referring to Fig. 1, the freeze dryer of the present utility model with hydrogen peroxide sterilization, including freeze dryer 30, vaporized hydrogen peroxide
