How the
Sanifoil Works:
- The leading edge is curved slightly upward, effectively captures CIP spray and redirects solution to the underside of the blade.
- The impeller-to-shaft union's strength is derived from its curved shape.
- The portion of the impeller closest to the hub is configured in a CIP-friendly vertical position to offset the slower relative speed near the center.
- The trailing edge is tapered to create an axial flow pattern, causing robust agitation and a uniform velocity across the length of the blade.
- The top surface of the hub is pitched for complete drainage allowing the cleaning surface to flow underneath the hub.
Sanitary Sanifoil Mixer Impeller
Canby, Oregon, March 2005 - JVNW has today received a patent for it’s Sanifoil Impeller. The new impeller was designed in response to increased demand for
improved clean-in-place (CIP) performance of top entering mixers.
The sleek “S” shaped design creates agitation patterns identical to standard impellers. The difference lies in the accessibility of the
underside of the blade to CIP cleaning solutions during the vessel cleaning process.
What:
The Sanifoil has been undergoing testing for nearly two years and is a combination of an Axial Flow and Radial Impeller blade that,
during the CIP process, allows the entire underside of the blade to be thoroughly exposed to the cleaning solution.
Why:
The underside of an impeller within a sealed pharmaceutical vessel is a cleaning challenge for the processor. Standard impeller designs
often create a CIP “shadow”, an area that is not reached during the cleaning cycle and is difficult to clean. The Sanifoil impeller
design has eliminated impeller CIP shadows.
Sanifoil Impeller comes standard in all JVNW mixing vessels.
