Nalco 1072 (Kieselsol or SilicaSol)

Nalco 1072 kieselsol is a liquid colloidal suspension of silicon dioxide, which is extremely effective in chillproofing and has been used in production of “vegan-friendly” beers. The resulting silica/protein complexes form relatively compact sediment cakes (tank bottoms) that aid in separation from the stabilized beer. Nalco 1072 is a ready-to-use solution that offers convenience in use.

Preparation of Stabilizers

These solutions come ready-made and can be added as described in the dosing section below.

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 kieselsol slurry 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.
