STERILIZATION OF LIQUIDS USING ULTRA-VIOLET LIGHT

摘要

A sterilizer for milk and other liquids is disclosed, the sterilizer having an elongate outer housing (12) with a manifold (16) at each end. Diary fittings (20) forming the inlet to and outlet from the sterilizer protrude from the manifolds (16). A sheath (26) of stainless steel extends along the housing (12) and a UV light fluorescent tube extends along the sheath. The sheath has an internal configuration providing protuberances over which the liquid to be sterilized flows. This imparts turbulence to the flowing liquid or, if the inlet manifold (16) and fitting (20) are themselves arranged to impart turbulence in the form of a swirling motion of the incoming liquid, help to maintain the turbulence throughout the length of the sheath (26).
