The non-transparent liquid UV sterilizer is a new high-tech product developed by the company. It targets industries like beverages, dairy products, and oils—where liquids have complex properties (non-transparency, viscosity, chromaticity, temperature) and existing disinfection processes are complex and costly. Combining UV sterilization’s advantages (convenience, speed, no impact on product active ingredients), it identifies the relationship between UV sterilization factors (irradiation distance/time, liquid thickness, temperature) and bacterial rate for non-transparent liquids through experiments.
