Kieselguhr brewing industry
Kieselguhr (diatomaceous earth)
This powder, which is made from diatomite, sedimentary rocks of skeletal remains of unicellular algae, named diatom. Amazingly complicated on the structure skeletons are unusual because they consist of clean silicon oxide – silicate. Many species have circular form but there are elongate or acicular too, but most of skeletons not preserve in the mining and milling processes. Uncountable interconnecting pores and solid, irregular shape are essential for correct work of this wonderful mineral.
For obtaining of high-quality diatomaceous products is required to ensure that:
- Mined diatomite rock is enough clean and without impurities of clay and other minerals
- Kept microporous structure survived
The reality is that only several diatomite deposits in the whole world are enough clean and more over in their mining required high accuracy in order to prevent of pollution. In addition to that particular attention to process of further processing for preserve diatomaceous structure from destruction.
In fact Imerys company explored whole our planet and warrants that it had exploiting only such deposits which are enough clean for production of first-class diatomaceous earth products.
It is the combination of inherently substance – of clean silicate, structure of disrupted diatomite particles and many holes in this structure provide with unique properties, inherent to products from diatomaceous earth. Mineralogical and chemical properties of diatomite rock are explored carefully before their mining. Because the most of our customers has business with beverage and food production, products by Imerys company are correspond according to standards of Food Chemical Codex, US Food and Drugs Administration and Generally Recognized as Safe.
Within beer production kieselguhr is one of the best filter aid. Disposal of several fractions with variety of permeability and particle size at the same time permits to:
- Improve filtration characteristics
- Decrease wearing of filtration equipment
- Increase filtration cycle
