Abstract
A 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.
Claims14
A photo bioreactor for pasteurization of liquid food products, the photo bioreactor comprising:
- a. one or more spiral-shaped tubes extending from an inlet end to an outlet end creating a fluidic pathway;
- and
- b. 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 and light above a wavelength of 300 nm;
- wherein the photo bioreactor further comprises one or more filters positioned between the one or more light sources and the one or more spiral-shaped tubes, wherein the one or more filters prevent the light above a wavelength of 300 nm from reaching the one or more spiral-shaped tubes.
