Abstract
A cassette system capable of a germicidal treatment of highly opaque liquids, featuring a filter, which prevents wavelengths above the UV-C spectrum reaching the liquid being treated, one or more spiral-shaped tubes extending from an inlet end to an outlet end creating a fluidic pathway, and one or more light sources illuminating the one or more spiral-shaped tubes, wherein the one or more light sources emit light in a wavelength range between 180-300 nm.
Claims16
A photo bioreactor for pasteurization of a liquid food product, the photo bioreactor comprising:
- a cassette mounting frame;
- one or more spiral-shaped tubes extending from an inlet end to an outlet end creating a fluidic pathway;
- at least two cassettes extending from a first end to a second end;
- and
- one or more filters;
- wherein the cassette mounting frame has cassette receiving openings into which each of the at least two cassettes are removably mounted,
- wherein each of the at least two cassettes comprises one or more light sources-illuminating the one or more spiral-shaped tubes, wherein the one or more light sources emit light in a wavelength range between 180-300 nm,
- wherein one or more of the one or more spiral-shaped tubes are positioned between two of the at least two cassettes and do not surround either of the two of the at least two cassettes,
- wherein the one or more filters are positioned between the one or more light sources and the one or more spiral-shaped tubes, and
- wherein the one or more filters prevent light above a wavelength of 300 nm from reaching the one or more spiral-shaped tubes.
