ABV Protosol (5kg)

Protosol is a specifically selected colloidal silica sol, which promotes sedimentation of proteins and other solids from beer and wort. Protosol effectively clarifies wort and beer at very low addition rates, enabling increased throughput of your brewery without the need for investment in tank or filtration capacity.

PRICINIPLE
The negatively-charged silica particles in Protosol associate to form hydrogel in the beer and this then interacts with the insoluble beer haze-forming particles. The resultant flocs precipitate to form sediment.

TREATMENT RATES
Protosol is typically added to beer at rates in the range 20–200ml/hl. The level of solids in the beer will determine the required addition rate. The correct addition rate is best identified by performing a lab-scale optimization test and assessing for clarity and sediment compaction.

APPLICATION
Protosol can be added to the chilled beer in-line during transfer from fermenter to maturation tank, to ensure thorough mixing with the beer.

STORAGE
Protosol should be stored at a temperature of 5-50°C. If allowed to freeze, irreversible precipitation will occur. Do not store in direct sunlight or bright light. Under ideal conditions, Protosol has a shelf life of 18 months in ideal conditions from manufacturing date.
