| Characteristics： | |
| Silica gel for Beer is a kind of non-crystalline micro-porous solid |
| powder, its pore diameter is 8-16 nm. 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 is justified |
| through practice that beer silica gel is the safest beer stabilizer
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. |
| How to Use: |
| 1.HY-950 is suitable for use on brewery production lines equipped
with diatomite filter. |
| Likewise, it can be filled into the diatomite precoating tank and
feeder of the filter. The |
| amount of filling is recommended as follows |
| | HY-950 | Diatomite | 1st precoating | Nil | 500g/m 2 filtering area | 2nd precoating | 50g/m 2 filtering area | 200-300g/m 2 | Main material filtering | 30-100g/HL | 80-100g/HL |
|
|
| (HL:per hundred liters of beer) |
| 2. Fill HY-950 in batches or continuously after fermenting and
before filtering. Filling in |
| batches: charges into the tank that is filled up with beer, keep
adsorbing for at least 5 |
| minutes. HY-950 silica gel can totally removed during filtering. |
| Continuous filling; continuously fills into beer at the given
amount and passes through a |
| container that can maintain it at a minimum of 3 minutes then to
the filter. |
| Filling amount is 300-500 ppm. |
| Filling amount can be determined using "acceleration testing
method". The method is also |
| used to check the stabilization effect. |
| Take two bottles of beer and measure them with a turbid measuring
gauge at the room |
| temperature (the values measured are the initial turbid level),
soak the specimens at below |
