摘要
为解决滚筒式回潮机在生产过程中因潮气排放造成的蒸汽耗量大、能源消耗高及在制品加工质量不稳定等问题,通过单因素和正交试验考察了影响排潮风量和松散效果的关键工艺参数(蒸汽施加比例、水施加比例、热风风速、水的引射蒸汽压力和环境温度),采用最小二乘法进行回归分析,确定了当潮气排放量为0时的最优工艺参数组合,并进行了生产验证。结果表明:①热风风速和水的引射蒸汽压力是影响潮气排放量的主要工艺参数。②环境温度为28℃时,满足松散回潮工序潮气零排放条件的最优工艺参数组合为:热风风速0.088 m/s、蒸汽施加比例2.74%、水的引射蒸汽压力0.15 MPa。③与传统方法相比,采用潮气零排放的松散回潮方法后,出口烟叶的温度和含水率CPK值均大幅提高;板结烟叶质量从平均5.3 kg/批降到2.1 kg/批;蒸汽总用量减少58.8%,风机总功率由原来的11.15 k W下降到0.04 k W。
During the running of conditioning cylinder, moisture exhaust results in high steam and energy consumption and inconsistent tobacco quality, therefore the key parameters influencing exhausted moisture volume and loosening effect were investigated via single factor and orthogonal experiments. The optimal technical parameters at zero moisture exhaust were determined by regression analysis with least square method,and production validation was conducted. The results showed that: 1) Hot air velocity and steam pressure for water ejection were the key parameters influencing exhausted moisture volume. 2) When the ambient temperature was 28 ℃, the optimal technical parameters at zero moisture exhaust were hot air velocity 0.088 m/s,steam application rate 2.74%, steam pressure for water ejection 0.15 MPa. 3) Comparing with traditional method, the CPK values of temperature of and moisture content in output lamina increased obviously, the amount of tobacco cake reduced from 5.3 to 2.1 kg/batch, the total consumption of steam saved by about58.8%, and the total power of fan decreased from 11.15 to 0.04 k W.
