Description
Technical field
This utility model relates to bactericidal unit, especially a kind of vacuum type steriliser for vacuum equipment.
Background technology
Chinese Pharmacopoeia is as further improving, in 2010 editions appendix sterilizations clear and definite aseptic freeze-dried be one of sterile production technique the most widely, be used for the device of the online sterilization of vacuum equipment by the chamber inner surface sterilization to vacuum equipment, create a gnotobasis that is suitable for pharmaceutical production, avoid in the freezing dry process medicine being caused the risk of microbial contamination.
At present online sterilizing methods mainly contains three kinds of steam sterilizations, ethylene oxide sterilizing, vaporized hydrogen peroxide sterilization.In above-mentioned three kinds of methods, the online sterilizing methods of oxirane because the high pressure of gas existence itself, the problem such as inflammable, explosive, poisonous substantially stop using at present; Steam sterilization is because easily so that produce larger pressure reduction variation in the sterilization chamber, equipment is needed certain requirement of withstand voltage, and damp and hot steam gas easily destroys the stainless passivating film of vacuum equipment chamber inner surface, cause shortened equipment life, and its energy consumption is high, need complicated pressure vessel and tubing, after the steam sterilization sterilization, need its cooling of wait consuming time before the use vacuum equipment in addition; And the vaporized hydrogen peroxide sterilization technology, because sterilization process good reproducibility, the method that safe, sterilising cycle is short, the harmless advantage such as pollution-free becomes pharmacopoeia of each country, GMP, disinfecting technical specification recommends, range of application is also extensive.
The problem that existing vaporized hydrogen peroxide bactericidal unit exists is: because employing is online sterilization under normal pressure, affected by internal structure and the turnover gas interface position of vacuum equipment, exist the interior sterilizing gas of chamber of vacuum equipment evenly not distribute, this is just so that sterilize not thorough in the vacuum equipment chamber, there is the sterilization dead angle, in freezing dry process, medicine has the hidden danger of microbial contamination.
The utility model content
The purpose of this utility model is: a kind of vacuum type steriliser is provided, sterilizing gas can evenly be distributed in the chamber of vacuum equipment, there is not the sterilization dead angle, sterilizes more thorough, avoid in the freezing dry process medicine being caused the risk of microbial contamination, the sterilization good reproducibility, safe, energy consumption is low, and operating cost is low, sterilising cycle is short, and is harmless pollution-free.
For achieving the above object, this utility model can be taked following technical proposals:
A kind of vacuum type steriliser of this utility model, comprise the intake interface, electromagnetic valve, preheater, vaporization pump, air filter for removing bacteria, electrodynamic valve and the interface of giving vent to anger that connect successively by pipeline, described intake interface is connected with compressed-air actuated source of the gas by pipeline, described vaporization pump is connected with the hydrogen peroxide medicine system by pipeline, the described interface of giving vent to anger is connected with the chamber of vacuum equipment through control valve by connection tube, described chamber is connected with the vacuum pump of vacuum equipment by the first bye-pass, and chamber is connected with the exhaust pump of vacuum equipment by the second bye-pass.
Also comprise the PLC electrical apparatus control system, described PLC electrical apparatus control system is electrically connected with the control system of vacuum equipment by communication interface and data wire.
Be connected with pressure regulator valve A, effusion meter and pressure regulator valve B between described electromagnetic valve and the preheater in turn.
Described electromagnetic valve is the sanitation-grade electrical ball valve; Described intake interface, the interface of giving vent to anger are the sanitation-grade quick coupling device; Described connection tube is connecting hose.
Comprise that also the color touch that is arranged on the vacuum type steriliser housing is shielded and the mini-printer of the every sterilizing parameter record of printout.
Compared with prior art the beneficial effects of the utility model are: owing to adopting technique scheme, the described interface of giving vent to anger is connected with the chamber of vacuum equipment through control valve by connection tube, described chamber is connected with the vacuum pump of vacuum equipment by the first bye-pass, chamber is connected with the exhaust pump of vacuum equipment by the second bye-pass, this structure has been utilized the original vacuum pump of vacuum equipment, to the chamber evacuation, then the hydrogen peroxide steam that passes into high concentration carries out sterilization treatment to the vacuum equipment chamber, after finishing, sterilization passes through repeatedly evacuation and emptying, with discharges such as hydrogen peroxide residual in the vacuum equipment chamber and catabolites thereof.Compare with online sterilization under the normal pressure of prior art, being more evenly distributed of this utility model sterilizing gas sterilized more thorough, there is not the sterilization dead angle, create a gnotobasis that is suitable for pharmaceutical production, avoid vacuum equipment medicine to be caused the risk of microbial contamination, and, the utlity model has the sterilization good reproducibility, safe, energy consumption is low, and operating cost is low, sterilising cycle is short, harmless free of contamination advantage after the sterilization.
