REMOVAL OF WEIGHED FRACTIONS FROM GAS EMISSIONS IN JET-BUBBLE CONTACTORS

Abstract

The production of dry milk products involves energy-intensive drying units where fine particles (0-30 μm) are often lost through exhaust air. While primary purification via cyclone banks achieves an efficiency of 95-97.7%, actual product losses can exceed 1% of the dryer's capacity, especially in older systems. Given that fine particles under 5 μm are prone to escaping these systems, there is a clear economic and environmental imperative to implement a second stage of purification. The analysis of experimental data reveals that the efficiency of capturing dry milk from the air stream is at least 99%.
