Abstract
A filter candle for a precoated filter for filtering and/or stabilizing fluids, especially beer, the filter candle comprising a tubular filter body that is formed from a spirally wound wire, with gaps being provided between the wire windings as fluid passages. To improve the adhesion of the precoated filter in such a filter candle, the surface of the wound wire that rests against the exterior of the filter body is inclined by an angle α relative to the longitudinal axis of the filter candle.
Claims7
A filter candle (1) for a precoated filter for filtering and/or stabilizing fluids, comprising:
- a tubular filter body (2) formed from a spirally wound wire (17) and having gaps provided between the wire windings as fluid passages,
- the surface (20) of the wound wire (17) that is the exterior of the filter body (2) being inclined by an angle α relative to the longitudinal axis (L) of the filter candle (1), and
- the wire (17) having a substantially triangular, inwardly tapering cross-section, with the baseline (f) of the triangle being the exterior of the filter body (2), thereby resulting in an offset of the surface (20) of successive wire windings.
A precoated filter for filtering and/or stabilizing fluids, comprising:
- a filter vessel (13) including an unfiltrate chamber (15) in which filter candles are arranged for filtering fluids, each filter candle having a tubular filter body (2) formed from a spirally wound wire (17), and having gaps (11) provided between the wire windings as fluid passages, the surface (20) of the wound wire (17) that is the exterior of the filter body (2) being inclined by an angle α relative to the longitudinal axis (L) of the filter candle (1), and the wire (17) having a substantially triangular, inwardly-tapering cross-section, with the baseline (f) of the triangle being the exterior of the filter body (2), thereby resulting in an offset of the surfaces (20) of successive wire windings.
