Beverage Clarification

Clarification, or separation of suspended solids from wine, is an extremely critical step in the processing of wine.

  • Not only is it important to leave the special flavour components untouched but also the disposal of filter aids, such as diatomaceous earth and sheet filters is becoming increasingly problematic in view of growing awareness of ecological and human health issues. Furthermore, the individual filtration steps that membrane filtration replaces are batch operated and need a lot of human attention and manual work.

Membrane Filtration: Advantages in Wine Production

  • Many manufacturers of automated filtration systems all over Europe use 3M™ Liqui-Flux™ Beverage Membrane Modules as original equipment in their processes.

    The advantages of using 3M™ Liqui-Flux™ Beverage Membrane Modules are:

    • One single step instead of several process steps
    • Low fouling tendency
    • No need for additional filter aids
    • Suitable for completely automated production plants
    • Easy to change from one to another type of wine
    • Low losses of wine
    • Wine filtration costs are reduced
    • No health hazards such as those associated with diatomaceous earth

    To further illustrate how simple and useful cross flow clarification with 3M™ Liqui-Flux™ Beverage Membrane Modules is, the following flow chart provides an overview of the wine making flow chart process.

Membrane filtration and advantages in wine production
  • The traditional fining after fermentation often involves a series of centrifugation and diatomaceous earth filtration steps to obtain the desired wine quality. The use of 3M™ Liqui-Flux™ Beverage Membrane Modules for microfiltration in a cross-flow system reduces the number of individual steps significantly and provides a durable economical solution for your wine clarification process.
