A filter aid for use in connection with the filtration of liquids is provided. In particular, a filter useful in connection with the filtration of beer is provided. In addition, a method of filtering liquids is provided. According to the method, a filter aid comprising angular, isotropic particles is introduced to a liquid before the liquid is passed through a filter. In particular, a method for filtering beer comprising the introduction of angular, isotropic particles as a filter aid to a stream of unfiltered beer such that a filtration cake comprising filter aid and solids filtered from the beer is formed.

Filter aid used in alluviation

Brewing method in which a suspension of cereals having undergone traditional mashing is boiled in the same kettle as that in which mashing is carrier out, with no hops present. Filtration in the method of the invention is carried out using a thin filter bed, i.e. a filter bed with a thickness between 20 mm and 60 mm, preferably on the order of 40 mm. The method is preferably carried out in an installation that includes a mash tub and at least one and preferably two or three kettles in which mashing and boiling takes place, the kettles being followed by a filter and preferably by a buffer tank and then by a cooler.

Filtration adjuvants, filtration supports, filtration process using them

There is disclosed a filtering method comprising using a filter-press-type device in the chambers whereof filtering means divide a compartment for material to be filtered from a filtrate-collecting compartment, compressing the possibly-washed material to be filtered by reducing the volume of the compartments for material to be filtered, discharging washing solute and filtrate which have passed through the filtering means, and dismantling said filter-press. The method makes use of filter means which are resistant and undistortable under the method conditions, and retains the filtering means in a relative position to the filtering chamber axis which is identical during all the filtering steps.
