Silica Gel for Beer
Characteristic:
Silica gel for beer is a kind of non-crystalline and micro-porous
solid powder, pore diameter is 8-16 nm. The chemical molecular
formula is mSiO2穘H2O. It is nontoxic, tasteless, flame-resisting
and non-explosive, and it is insoluble in water or any other
solvent (except for caustic soda and hydrofluoric acid). It does
not react with any acid, alkali or salt, so has high stability
under hot and cold atmosphere and is harmless to human body, mainly
used in beer industry.
Technical Data:
ITEM | Specifications |
Pore volume, ml/g | 0.9-1.5 |
Specific surface area, m2/g | 300-600 |
Size (D50), 祄 | 7-15 |
pH | 3-6 |
Moisture, % = | 8.0 |
Heavy metal (by Pb), % = | 0.003 |
Lead (Pb), % = | 0.001 |
Arsenic (As), % = | 0.0003 |
Note:
1. Due to large specific surface area and pored structure, it can
prolong beer storage period by 180-240 days and keep beer from
being cold muddy.
2. It does not affect the beer foam or taste.
3. It helps improving the filter promoting effect. It can be a good
promoter with diatomite filter, and make beer brighter and clearer.
4. While used, the amount of fine diatomite can be reduced
according to the amount of beer silica gel, in order not to affect
the filtered amount.
5. If the starting filter pressure is too fast and affects the
output, we can supply of fast filtering speed
