  • the invention relates to a method and a device for precoat filtration of a non-filtrate, which is preferably beer.
  • This precoat filter is constructed in the form of a horizontal filter. It contains a filter vessel and in this arranged on a common shaft horizontal filter elements having at least on their upper side a porous liquid-permeable Anschwemmunterlage for filter aid.
  • the precoat underlay is a finely porous membrane which replaces the first alluvium of the otherwise usual filter aid.
  • the filter cartridge is intended for suspended installation in a filter vessel. It has an end piece for connecting the filter candle to a dividing wall of a precoat candle filter, preferably to a connecting piece arranged in the dividing wall. Furthermore, it contains a candle wall, which forms an active filter layer together with a washed-on precoat layer. Furthermore, it contains a closure piece for separating a candle interior from a non-filtrate space, wherein a dip tube is arranged inside the candle, which, when used as intended, extends from outside the end piece through the dividing wall and the end piece into a lower end portion of the candle interior.
  • At least one opening in the dip tube is provided. Between the dip tube and the tail a gap is formed.
  • These measures are intended to make available a filter candle which retains only a small residual amount of filtrate and can be vented as completely as possible. Furthermore, these measures should provide a precoat candle filter, which at a phase change, z. B. of water on beer, the lowest possible phase cut allows.
  • the object of the invention is to provide a method and a device for precoat filtration of a non-filtrate, in which the oxygen uptake and beer losses are further reduced.
  • the advantages of the invention are, in particular, that it is not necessary to pre-soak in a conventional precoat filtration for applying a filter aid, since the filter medium used for precoat filtration, which is preferably a number of filter cartridges, is already from the beginning a filter aid is provided.
  • This filter aid is advantageously pressed onto the filter medium or fired on this.
  • Such a filter medium can be applied directly to the liquid to be filtered, which is preferably beer, without the need for pre-infiltration.

If a high turbidity level of the filtered unfiltered material is measured, then the number of filter cartridges used for filtration is selected to be large. If, on the other hand, a low degree of turbidity of the filtered unfiltered material is measured, then the number of filter cartridges used for filtering is chosen to be small.
  • the number and selection of the filter cartridge modules used for the filtration can be changed depending on the measured turbidity level and / or on a pressure difference.
