INTENSIFICATION OF THE ABSORPTION OF OXYGEN BY WATER USING A ROTOR-PULSATING APPARATUS

One of the important components quality food products is water used. A common way to remove unwanted impurities from aeration, i.e. oxidation chemical compounds in by oxygen. Aeration devices with mechanical energy input comparison other groups devices, namely gas phase and liquid phase, have low power consumption additional mixing processed medium. The work presents a study oxygen absorption an experimental setup rotor-pulsating apparatus for treatment beverage production technology. In this paper, technological parameters aeration model aqueous solution certain concentration sodium sulfide as aerator are determined. allows conducting research several modes consists particular vessel, apparatus, two ejectors - one at entrance rotor-pulsating, outlet, recirculation pipeline. Air atmosphere enters each through separate air duct. studied took place mode 20 minutes. Determination mass transfer rate determined iodometric titration method on sulfite. Experiments were conducted without using catalyst. It that when placing ejector unit inlet angular rotor velocity 240.02; 270.18, 300.02 s-1, 1.39; 1.49 1.73 kg m3/h. At location outlet under same conditions 1.17; 1.36 1.63 m3/h respectively. However, second scheme exceeds first 50%.
