FIELD: food industry.
SUBSTANCE: invention relates to food industry. According to proposed method disinfection of a liquid product with controlled film thickness and exposure to ultraviolet radiation takes place inside a vertical working cylinder, where a required film thickness of falling fluid is formed, determining its consumption. Optical characteristics of emitter and receiver are matched, and source of ultraviolet radiation disinfects liquid product on entire thickness of layer thereof.
EFFECT: method considerably improves quality of treatment of liquid product with considerable reduction of power consumption.
