Pure steam cleaning (PS cleaning) uses a specified boiler system to generate pure steam at a temperature of 121°C or higher using RO water (RO membrane treated water) as the raw water, and fills various products and containers for cleaning and sterilization.
Pure steam generator (boiler, tank, etc.)
Condition of inner surface of container after electropolishing (EP) and before PS cleaning (1) (Before installation)
Electrolytic solution and other substances adhering to the surface after cleaning after electropolishing are blown off by high-pressure washing.
Condition of inner surface of container after electropolishing (EP) and before PS cleaning (2) (Before installation)
If you look closely at the inner surface of the tank, you can see that even after cleaning, some electrolyte and other contaminants have adhered to the tank.
Interior view of the tank after pure steam cleaning (PS cleaning) (After installation)
Pure steam cleaning (PS cleaning) and re-cleaning is repeated several times to float and remove various contaminants and clean the inside of the container.
Filter for rinsing liquid
The inspection takes place after the last rinse wash is completed. The rinse effluent is passed through a filter and the cleanliness of the container is measured by the amount of dust remaining in the filter.
Pure steam cleaning (PS cleaning) improves the quality of the final processed product by removing components, dust, etc. associated with the processing of the product. It also provides excellent stability of surface quality in long-term use.
*In this case, VINA ASTEC is in charge of the pure steam cleaning, but is not involved in the manufacturing of the tank itself.
