加料引射蒸汽压力对料液施加均匀性的影响

Effect of Casing Flavour Injection Steam Pressure onthe Uniformity of Casing Application

对不同加料引射蒸汽压力下的料液施加均匀性、烟叶筒壁黏附量、加料喷射状态等进行了分析研究,结果表明,1.2×10^(2)~1.8×10^(2) kPa的加料引射蒸汽压力范围内,设置不同的加料引射蒸汽压力,料液的雾化效果和喷料观察正常,加料流量正常,出料烟叶温度和水分正常,但是加料均匀系数和筒壁黏附量均有不同,具体表现在随着加料引射蒸汽压力设置值从1.7×10^(2)/1.8×10^(2) kPa逐渐降低到1.2×10^(2)/1.3×10^(2) kPa,加料烟叶样品呈现标准偏差降低,加料均匀系数升高,烟叶筒壁黏附量降低的良好趋势。通过试验测定,在1.2×10^(2)~1.8×10^(2) kPa的加料引射蒸汽压力范围内,1.2×10^(2)/1.3×10^(2) kPa时的加料均匀性较好,筒壁烟叶黏附量较少;1.7×10^(2)/1.8×10^(2) kPa时的加料均匀性较差,筒壁烟叶黏附量较多。同时,通过研究可看到,在加料技术标准制定时,有必要结合现有直观观察为主的加料技术标准要求,引入加料均匀性化学数据分析方法,从直观现象观察和科学数据分析的角度综合评价加料均匀性,确定一个加料均匀性较好的加料引射蒸汽压力标准值,以提高加料均匀性、降低加料烟叶筒壁黏附量,进而提高加料和卷烟产品品质。

Studying the uniformity of casing application and the adhesion amount of casing cylinder within the spraying state of casing as different casing flavour injection steam pressure,the result showed that the casing flow rate was normal within different casing flavour injection steam pressure and parameter,the atomization effect and the observation of normal casing flavour injection,the temperature and moisture of the discharged tobacco leaf was normal within the pressure range of 1.2×10^(2)~1.8×10^(2) kPa for casing flavour injection steam pressure.The uniformity coefficient of casing and the adhesion amount of casing cylinder was different.Specifically,as the steam pressure setting value of casing flavour injection gradually decreases from 1.7×10^(2)/1.8×10^(2) kPa to 1.2×10^(2)/1.3×10^(2) kPa,the standard deviation of the casing tobacco sample showed a good trend of decreasing.The uniformity coefficient of casing showed a good trend of increasing,as same time the adhesion amount of casing cylinder shows a good trend of decreasing.Through experimental measurements,it was found that within the steam pressure range of 1.2×10^(2)~1.8×10^(2) kPa,the uniformity of casing was good at 1.2×10^(2)/1.3×10^(2) kPa with less the adhesion amount of casing cylinder.The uniformity of casing was unsatisfactory at 1.7×10^(2)/1.8×10^(2) kPa,throwing up more the adhesion amount of casing cylinder.The studying confirming that when formulating casing technology standards,it was necessary to combine existing intuitive observation based casing technology standard requirements and introducing chemical data analysis methods for casing uniformity.By determining a standard value for casing flavour injection steam pressure with good the uniformity of casing to improve the uniformity of casing,it draw into comprehensively evaluate casing uniformity from the perspective of intuitive phenomenon observation and scientific data analysis.Thereby improving the quality of casing and cigarette products,it reduce the adhesion amount of casing cylinder.
