Britesorb A100 Hydrogel
Britesorb A100 – Silica Hydrogel is an amorphous silica powder, which is non-dusting and free flowing, and has a moisture content of approximately 65%. BRITESORB A100 works through size exclusion. The surface of BRITESORB A100 is engineered with a moderately sized porosity, which selectively allows for the internal adsorption of haze-forming proteins while retarding the entry of larger, foam-positive proteins. An excellent choice for chillproofing lighter style beers, BRITESORB A100 has a high permeability factor that allows for faster filtration rates and longer filter runs. powder, and inorganic filter aids.

Preparation of Stabilizers
The amorphous powder should be mixed with deoxygenated water at a 10% w/w ratio. (1 kg powder: 10 liters DAW or ~8 lb: 10 USG DAW). The use of a CO2 sparger in the slurry water will help to deoxygenate the water. Agitate slurry for at least 20 minutes prior to addition.
Dosing of Stabilizers
- Inline Method: Slurry is dosed proportionally into the beer stream by means of a metering pump. The products are allowed react with the beer. Depending upon contact time required for each product a buffer tank may be utilized. Resultant sediments can be removed via centrifuge and/or filtration.
- Batch Method: Add the Silica Hydrogel into the product while filling the finishing tank. Add the stabilizing agent proportionally during the fill or as a single shot method through the spray ball arm. Once the stabilizing agent has reacted with the respective protein or tannin, it will settle to the bottom of the tank as sediment. Settling times vary due to tank geometry and stabilizer/protein/tannin complex size. The stabilized beer can be separated from the sediment prior to filtration and any leftover sediment is easily removed during CIP. Inadvertent over-dosing or contact time of several days causes no negative effects in the beer.
