Description: Characteristics:
Silica gel for Beer is a kind of non-crystalline micro-porous solid powder,its pore diameter is 8-16nm.Its
chemical molecular formula is mSiO2.nH2O,insoluble in
water or any other solvent (except the caustic alkali and hydrofluoric acid). It does not react with any acid, alkali or salt. It is nontoxic, tasteless,flame-resisting and nonexplosive.It possesses high stability under hot or cold atmosphere and is harmless to human body,mainly used in
beer industry.
Use:
1. It has large specific surface area and numerous fine-pored structure.It adsorbs the proteins which cause
beer turbid and removes them through filtering,just within several minutes,thus prolonging
beer storage period by 180-240 days and keeping
beer from being cold muddy.
2. It does not affect the
beer foam or taste.Thanks to its superior physical and
chemical properties,it does not have any adverse effect on the
beer foam or taste.It generally recognized by the world
beer industry.
3. It helps improve the
filter promoting effect.It is chemically stable,contains no
beer soluble substances,Its surface area and porous structure are both superior to diatomite.It is a kind of ideal
filter promoter in aiding diatomite filter,making
beer brighter and clearer.
