Abstract: In order to promote the control precision of moisture content in tobacco strips and reduce steam and water consumption during strip redrying, the moistening system in the reordering section of strip redryer was modified by isolating water from steam, multi-zone multi-point injection and precise control of water supply. The pipeline system for steam-water mixing nozzle was removed, and steam pipeline and water pipeline were controlled separately. The system automatically controls the water supply to the high pressure water atomizing nozzle according to the moisture content in the strips at outlet to achieve the precise control of temperature and water application. A KG235C strip redryer was tested, the results showed that the heating and humidifying in the reordering section were controlled automatically, the precision of moisture control reached 0.1%. The coefficient of variation of moisture content in strips increased by 0.42 percentage points, steam and water consumption reduced by 35.2% and 85.3% respectively. This technology provides a support for promoting the homogenization of tobacco strips.
