Title:
GAS STERILIZING SYSTEM
Document Type and Number:
Japanese Patent JP2664019
Kind Code:
B2
Abstract:
PURPOSE: To enable easily handling a gas having the nature of killing bacteria by providing a computer means which executes a predetermined step sequence so that an article processing device is put into cyclic action.
CONSTITUTION: Sensor inputs 5 including signals related to temperature, pressure, moisture, and sterilizing gas concentration within a chamber 10 are fed from the chamber 10 to a control circuit 100. A valve and pump portion 20 includes a chlorine dioxide gas source 22, steam, and nitrogen 24. The valve and pump portion 20 includes a valve controlled by numerous steps of sequence control and a vacuum pump for imparting necessary conditions to the inside of the sterilizing chamber 10 at the proper time. A control signal 7 is fed to the valve and pump portion 20 and the chamber 10 by an electronic control circuit 100 to control elements, and signals 8 fed back from the elements are fed to the control circuit 10. The electronic control circuit 100 has a computer means for executing a predetermined step sequence so that an article processing device is put into cyclic action.
