Fibrous deposits formation preventing device for use during filtration of e.g. wort, has scrapper member carrying out intermittent/continuous scrapping or chopping action in common input plane of beam of capillary or tubular membrane

摘要

The device has a filtration module (4) filtering turbid liquid containing organic particles e.g. precursor of fibrous materials. A functional unit i.e. scrapper member, (5) carries out an intermittent/continuous scrapping or chopping action in a common input plane (PE) of a beam of a capillary or tubular membrane (3) of the filtration module or in a plane parallel to the plane (PE). The member with a scrapping flange (2) circulates at a determined distance with respect to the plane or in the plane, where the member is pivoted around a perpendicular axis and centered with respect to the plane. An independent claim is also included for a filtration system comprising a tangential filtration module.
