ORSCH offers a Wash-in-Place and high-containment execution (WipCon®) which permits a containment level of OEB 4 or OEB 5.
The WipCon® execution is designed and built based on two main technical requirements: dust tightness suitable for OEB 4 and OEB 5 (compression zone as an isolator with inflatable seals) and Wash-in-Place functionality with comprehensive sealing. The glove ports, RTP, and negative pressure control are included as standard in the WipCon® execution. It is important to note that PPE is not required for any aspect of the WipCon® setup, operation, or cleaning.
All KORSCH models configured with WipCon® technology include compression zones of certified stainless steel and special plastic materials that are suitable for washing using hot water up to 60° Celsius with acidic or alkaline detergents.
The WIP cleaning sequence begins with a prewash cycle which removes any residual powder and airborne particulate from the compression zone. The initial prewash and wetting the interior of the press makes it possible to dismantle certain components, including the compression tools, via the glove ports and RTP. This makes further cleaning easier. Depending on cleaning requirements and solubility of the active material, dismantled machine components can also be removed from the compression zone in a contained manner via an RTP prior to the full WIP sequence.
In subsequent wash cycles, all tubes are wetted completely, and a series of spray nozzles are activated in the compression zone for a preset time duration. The WIP sequence also incorporates the peripheral equipment including the deduster, metal detector,
