Abstract
An improved radial flow cell, comprising two or more sets of inlet port-groove-dam devices for improving the efficiency of radial flows and an efficient filtration device consisting of a micropore membrane and a steel screen support of low retention volume, is useful for aseptic and continuous in-line filtration of heterogeneous mixtures containing high concentrations of solids especially those resulting from fermentation processes.
Claims2
An improved radial flow cell of the type having
- (a) a feeding plate with means for feeding a heterogeneous broth;
- (b) a filter plate with means for filtration;
- and
- (c) a sealing means for securing the feeding plate and the filtrate plate together so as to form a leak-proof cell, wherein the improvement comprises means for feeding which further comprises
- (1) two or more circumferentially located inlet ports for feeding a heterogeneous broth;
- (2) a circular groove for receiving via connecting orifices the broth from the inlet ports and thereby generating a radial flow of broth;
- (3) a dam attached to the periphery of the bottom surface of the feeding plate and facing the connecting orifices for enlarging the radius of the radial flow from the circular groove;
- and
- (4) two or more outlet ports with enlarged openings to facilitate the exit of the concentrated process stream.
