Abstract

A filter for solid matter, e.g. fruit pulp, contained in a liquid the freezing point of which is lower than that of water comprises discrete particles of ice maintained at a temperature below 0 DEG C. The filtrate is recovered by melting the ice. The ice particles may be contained between sheets of screen cloth and the liquid filtered upwardly. Specification 617,776, [Group VI], is referred to.ALSO:Solid matter such as fruit pulp contained in fruit juices which have been concentrated by freezing as described in Specification 617,776 is separated by passing the liquid through a filter bed comprising discrete particles of ice maintained at a temperature below 0 DEG C. The filtrate is recovered by melting the ice.
