摘要
【目的】开展生物质成型颗粒烘烤烟叶效果试验,为烟叶烘烤的减工降本、提质增效提供参考。【方法】选取标准气流下降式密集烤房,设常规燃煤烘烤和生物质颗粒燃料烘烤2个处理,对比分析两种处理的烘烤用时、烘烤成本及烤后烟叶的经济性状、化学成分和评吸质量。【结果】使用生物质颗粒燃料烘烤烟叶可节省烘烤时间,其中添加燃料、清灰时间较燃煤处理节省14 h以上。生物质颗粒燃料烘烤处理的用电成本和燃料成本高于燃煤处理,但人工成本可节省177.50~180.00元/炉,每千克干烟叶烘烤成本较燃煤处理平均降低0.16元。与常规燃煤烘烤处理相比,生物质颗粒燃料烘烤处理可提高烤后烟叶的均价、上等烟比例、中上等烟比例等指标,其烟叶化学成分含量适宜、比例协调,特别是中部叶烟碱和总氮含量较低,钾含量较高,淀粉含量较低,烤后烟叶的感官评吸质量相对较优。【结论】烟叶烘烤中使用生物质颗粒燃料替代燃煤可实现减工降本、提质增效。在相应政策扶持下,生物质颗粒燃料烘烤烟叶技术可进一步推广应用。
【Objective】The experiment was conducted to study the effects of biomass pellet fuel on tobacco curing so as to provide reference for reducing tobacco curing cost and improving the quality and efficiency.【Method】The treatments of conventional coal curing and biomass pellet curing were set to compare the curing time,curing cost,economic characters,chemical components and smoking quality of flue-cured tobacco by using the standard airflow descending bulk curing barn.【Result】The use of biomass pellet fuel could save curing time,especially adding fuel and cleaning ash time was saved for more than 14 h compared with coal treatment.Although the fuel cost and electricity cost of biomass pellet fuel were higher than that of coal treatment,but the labor cost was saved from 177.50 to 180.00 yuan/oven,so the total cost for 1 kg dry tobacco leaves was 0.16 yuan lower than that of coal treatment.Compared with the conventional coal curing,the use of biomass pellet fuel could also increase average price,proportion of superior leaf and proportion of medium and superior leaf.The chemical component contents were proper and in harmonious proportion.Medium tobacco leaf contained low content of nicotine,total nitrogen and starch,and high potassium content,the sensory evaluation of cured-tobacco was also superior.【Conclusion】Biomass pellet fuel can be used instead of coal in tobacco curing,which can reduces the amount of labor and output,and improves the quality of tobacco leaves.Under the support of the corresponding policy,the technology of biomass pellet fuel on tobacco curing can be further applied.
