Application
The static TPX mixer is used for continuous mixing of different
combinations of liquids, gasses, and particles. It is also well suited
for ensuring an equal mixing temperature by for example direct
steam injection. The static mixer can be used for both pre-and
post-mixing. It can be used for mixing of dairy products such as
cream and milk by standardisation, starter culture and milk, and fat
and recombined milk.
The TPX static mixer is characterised by low energy consumption.

The mixer is an in-line mixer and has no moving parts. The static
mixing element in the mixer housing ensures that the liquids are

stainless steel AISI 316 L / DIN1.4404.
• Contains of four helical mixing elements. If more mixing
elements are required, more mixers can be serial
connected.
• Seal material in EPDM or FPM (Viton), FDA quality

separated, spread, rotated, and whirled so that they are properly
mixed. This takes place with a minimum of pressure loss. The
liquid flow is ensured by either a pump or by gravitation.
The mixing elements are twisted 180o to the left and right
alternately and are adjacent in 90o angles to each other.
The mixing takes place by either laminar or turbulent flow. For high
viscosity products the aim is laminar flow, whereas mixing of low
viscosity products is preferred by turbulent flow. For low viscosity
products and turbulent flow four mixing elements will be sufficient
to ensure a homogeneous mixture.

For laminar flow the liquid will be divided in two by each mixing
element and simultaneously the direction in which the liquid
rotates will change. The division of flow, the number of liquid flow
