Hygienic and low on maintenance

Fluitec CSE-W and CSE-X mixers destined for the food processing industry have electropolished surfaces and are manufactured with dairy couplings or Tri-Clamp connections, so that they are suitable for use in sterile areas.

Static mixers are a particularly efficient alternative for the following types of process:

– Admixing aroma compounds
– Diluting extracts
– Heating and cooling chocolate masses
– Gasifying beer, wine, juices or coffee extracts
– Pasteurising foods with steam
– Making mustard, fruit yoghurt or jams

CSE-W and CSE-X mixers traditionally play an important part in many different applications.

In no other industry does the quality of the end product more closely depend on the process components than in pharmaceuticals and biotechnology.

The individual quality requirements of each process are determined by the following factors:

– Process stability / quality assurance (contamination, dead spots, dead legs, etc.)
– GMP and CIP aspects
– Cost effectiveness with regard to plant engineering and operation

In order to meet the process requirements the surface finish of the mixers are of absolute importance to reduce or eliminate product contamination. Two qualities are defined for the pharmaceutical industry: Swiss Finish 1 and Swiss Finish 2.

Swiss Finish 1 (low-cost version)

This is a TIG welded mixer (141), assembled by qualified welders, with a maximum ferrite content in the weld seams of 1.5 to 2% (< 3%). The welds, which have a fine ground finish, are pickled and then electropolished, so that the surfaces in contact with the medium have a roughness RA < 0.8 μm while those not required to contact the medium have a roughness RA > 0.8 μm. The ports are prepared for orbital welding and adequately protected for transport. All medium contacting parts are newly stamped, labelled and identified in the documentation with an EN 10204- 3.1 certificate. The mixer is accompanied by a declaration of conformity based on the PED as well as an in-process inspection plan.

Swiss Finish 2 (high-end version)

This is an orbitally welded mixer with a maximum ferrite content in the weld seams of < 0.5%. The welds are unfinished and electropolished, so that the surfaces in contact with the medium have a roughness Ra < 0.8 μm while those not required to contact the medium have a roughness Ra > 0.8 μm. The ports are prepared for orbital welding and adequately protected for transport. All medium contacting parts are newly stamped, labelled and identified in the documentation with an EN 10204- 3.1 certificate. The mixer is accompanied by a declaration of conformity based on the PED as well as an in-process inspection plan. The ferrite content measurement at the weld is invoiced on an actual cost basis.
