Filter aid for the filtration of beer

摘要

The invention relates to a filter aid for filtering a liquid, such as beer, in a filtration device working on a defined filtration velocity, said filter aid consists essentially of particles of a material A, wherein the flotation velocity UoA is measured as <DF>UoA = d<2> Ag DIVIDED 18 mu ( rho - rho a), </DF> wherein dA is the diameter of the particle, mu is the viscosity of the fluid, rho is the density of the fluid and rho a is the density of the particle. The invention further relates to the use of said filter aid as a precoating material in a candle filtration device and to the candle filtration device comprising a number of candles provided with a precoat consisting essentially of the filter aid according to the invention and to a filtrated liquid, for example alcohol and more in particular beer, obtained via a filtration method using a candle filtration device.
