Perlite Filter Aid for Breweries

Perlite is the generic name for a naturally occurring siliceous volcanic rock, which we take into our new a modern factory outside Copenhagen in shiploads. Here we are manufacturing the filter Perlite in one of our special kilns at temperatures of around 1100o C, whereby the original raw material is expanding up to 20 times its original volume, and we achieve a new product : a white, sterile granular with many properties and many areas of use.

Especially around the equipment of the company Nordisk Perlite, the particles are in a special form and structure, which means that you can get a filter cake with infinitive myriads of microscopic channels, which achieves an optimum flow rate and clarity of the liquid. This results to the following:

    High quality of filtration
    Optimum flow rates
    Colour of the Perlite is white
    Very low density 90-100 kg/m3 i.e., 1 bag of Perlite (14/17 kg replaces 1 bag of other types filter-aids, like Kieselguhr (23 kg or more)
    Average Particle size from 7µ – 35µ = covering from the finest to the coarsest products on the market.
    Perlite filter aid qualities is an amorphous material, without crystalline particles, i.e., no lung injuries, no allergy, no skin irritation ,when using our products and qualities.
    pH value: 6.5 – 7.5
    Chemically inert
    Virtually Insoluble
    Sterile
    Perlite does not impart taste, odour, colour and is listed in the US Food Chemical Codex, recognized by the U.S. Food and Drug
    Administration (FDA)
    Easy to clean the filter cloth
    DIOXIN & PCB’s. Figures tested are significantly below current and proposed limits according to the EU Directive 2002/32/EU

Greater efficiency

In almost every major industrial filtration application, our Perlite filter aid has proved remarkably efficient. The ability to filter “hard-to-clarify” liquids while maintaining maximum “flow rates” has built a record of performance unequalled by most competitive filter aids.
There is a Perlite filter aid quality for filtration of all kind of beers.
Filtration of beer and the way filtration is done differs from brewery to brewery!

It is cost effective to change filter aid media from diatomite earth or Kieselguhr to Perlite filter aid. Our Perlite is on average 20 – 25% lighter in weight than the diatomite material. At filtration properties one looks at the volumes rather than weight, which is why the consumption of the “filtering aid” is reduced considerable. The cost savings are around 20 – 25% when using our Perlite filter aid.

Perlite Filter aid is a filter aid, which over the last 50 years has proven itself being a superb material within a number of industries, i.e.

    Chemical Industries
    Food processing- & drink industries
    Pharmaceutical Industries
    Water treatment and others

Grade Selection

Clarity is considered by many engineers to be the most important measure of efficiency in filter aid filtration. A high quality filter aid is most important for uniform results day after day. Selection of the particular type and grade of filter aid having the correct particle size and distribution is a major factor. After these come many considerations such as the quantity of filter aid to be used; flow rate needed to meet plant production schedules, equipment limitations and general filtration conditions. All of these can best be resolved by tests using the actual liquid involved.
