As cleanliness is a priority for the pharmaceutical manufacturer, an important feature of any IBC system is the ability to wash containers to a consistent, repeatable standard, both externally and internally. An extensive selection of washing systems has been created to suit the diverse needs of the market — and to minimize production downtime. These range from simple internal wash systems to fully automatic washing, drying and cooling booths.
Wash stations may be single entry or pass through, loaded by pallet truck, AGV or conveyor. They can be manually operated or fully automated for PLC-based wash cycle selection. Metering controls the addition of detergents or sanitizing fluid to the system and, if needed, purified or municipal water. A standalone service module supplies air drying and cooling, as well as housing a heat exchanger, valves, pumps and detergent tanks. Depending on throughput demands, single or multiple units may be used.
BUCK® Valve Washing
Although it is important to handle and transfer powders in a contained way to prevent operator exposure, it is equally important to be able to wash the IBC and the containment valves in place without the need for operator intervention. All the BUCK® IBCs and their passive valves are designed to be fully cleaned in place (CIP) within the Buck Wash Station.
CIP of the Passive Valve is achieved using the Buck Wash Active Valve. The wash valve assembles are mounted in the top and bottom of the booth to wash the IBC’s passive valves (inlet and outlet). The wash valve assemblies automatically dock with the Passive Valves on the IBC and open the valve, allow for the main wash nozzle to be inserted into the IBC and for the wash water to drain away. The unique cruciform wash disc allows coverage of the external face of the passive valve, whilst the dirty internal face is cleaned using strategically placed wash nozzles.
The Active Wash Valves can easily allow ‘Internal Only’ washing of the IBC. The IBC can be loaded onto a wash stand. The Active Wash Valves are then docked. Wash water is contained within the system. With the containment valves of the system preventing the contamination of the external surfaces, clients now have the opportunity to remove the wash booth that provides the external washing, saving on upfront capital costs, space and ongoing maintenance costs.
