Protosol

Clarifies and helps filtration capacity

Overview

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

Principle

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 optimisation 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.

Packaging and 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.
Protosol is available in 5kg and 25kg package sizes.
