    Study on the enhancement of mass transfer in convective drying process of cut tobacco

    LI Bin; LIU Ze; YU Chuanfang; ZHU Wenkui; WANG Hongsheng
    Zhengzhou Tobacco Research Institute of CNTC, Zhengzhou, Henan, China
    The cylinder drier is widely used in the tobacco primary process. It combines the convective heat from the hot air inside the cylinder with the conductive heat from the cylinder wall to dry cut tobacco. Most of the former researches have focused on...

    Research on X-ray attenuation method for non-destructive detection of lamina density variation rate (DVR) in cases

    LI Bin; FENG Qian; LIU Gangyi; LIU Ze; HU Qixiu; CHEN Liangyuan
    Zhengzhou Tobacco Research Institute of CNTC, Zhengzhou, Henan, China
    The density deviation is one of the significant factors that influences the tobacco aging and primary process. For example, the phenomena of oil loss, caking, or even carbonization takes place easily in the aging process because of the large density...
