FUNDAMIX® Vibromixer

Improve your bioreactor mixing by oscillation, not stirring

Mixing by vibration

The FUNDAMIX® is a sophisticated mixing device where the mixing effect is generated by high frequency vibration created by an electromagnetic drive. The vibration is transferred through the length of a shaft to a perforated mixing plate with conical bores. The oscillation of the plate causes the liquid to be pumped through the conical holes, creating a flow according to the Bernoulli effect.

The FUNDAMIX® membrane sealing unit options offer a low maintenance solution perfectly suited for a sterile environment. The absence of rotating parts results in the seal being guaranteed with use of a simple membrane, capable of withstanding both full vacuum and pressure up to 5 bar g or higher upon special request. The membrane seal design does not generate any friction unlike rotating devices and is well suited for both CIP & SIP processes.

Mixing devices are designed according to the customer and process requirements to guarantee optimal mixing performance, constructed according to the hygienic design principles and supplied with all supporting documentation.

The flow direction can be adapted to suit the application or desired mixing effect, the mixing direction depends on the orientation of the conical bores. The FUNDAMIX® mixing technique generates fast, homogenous product dispersion without a vortex and if required, with minimal surface movement.

We offer a wide range of control equipment, from standalone devices to bespoke control cabinets. Our range of controllers are well suited for integration with existing PLC systems via a selection of communication interfaces.

Where mixing conditions are changing, we have developed an amplitude monitor that provides real time measurements from an accelerometer fixed to the mixing device shaft, a set amplitude from 0-4mm can be defined via the controller interface and the device will make the required power adjustments to maintain the set point within an accuracy of 0.1mm.

For devices that are to be installed within an explosive environment we are able to provide ATEX certified equipment for zones 1 & 2.

Types of Mixing Plates

Stirrer Plate Type A

Type A with the conical bores facing upwards is the preferred standard. Type A has higher efficiency due to upward flow through the whole vessel. The plate can be mounted very low, so the mixable heel volume is reduced to a minimum.

Stirrer Plate Type B

Mixer type B with the conical bores facing downwards is chosen if the product tends to sediment, creates foaming or if no air is to be introduced during mixing. The distance to the bottom of the vessel is about the diameter of the plate.

Stirrer Plate Type B with Gas Dispersion

If gas is required, then it can be injected through the shaft with mixer plate type B. The liquid flows downwards distributing the fine gas bubbles in the vessel generating an excellent gas dispersion. Another well proven set up is to inject the gas between two plates to break the bubbles.
