富氮低氧气调密封储存对初烤散烟的影响

为保障广元市仓储烟叶质量、减少经济损失,开展了富氮低氧气调密封储存对初烤散烟中橘三(C3F)、上橘三(B3F)的影响研究。结果表明,富氮低氧气调密封储存能有效阻止烟叶霉变,并对外观质量有一定提升作用。富氮低氧气调密封储存的烟叶平均每包(40 kg/包)增加的重量明显高于自然环境下储存的烟叶,特别是上橘三(B3F),平均每包烟叶增重量较自然环境储存增加了0.46 kg。由此说明,富氮低氧密封储存技术能有效保障广元市烟叶在仓储过程中的质量。

Determinations of Air Tightness of Covered Slurry Storage Tanks Using Tracer Gas Technique

The objective of this investigation was to study whether it is possible to determine the air tightness of covered slurry storage tanks using tracer gas technique by injection of sulphur hexafluoride （SF6） and measurements of the decay in gas concentrations with an infrared spectrophotometer in the air space above the slurry. By measuring the decay in concentration of injected tracer gas at different occasions, the air exchange rate was determined. Three different types of coverings were studied namely; wooden roof, plastic tent and concrete roof.

减少油料变质的措施

1.合理选用容器 为减少阳光的曝晒,盛油容器的外表要选用银灰色、白色等浅色的油漆,以反射阳光,降低油温。储油容器内不要直接用钢制零件,钢制油罐的内壁要涂防锈层,以避免金属对油料的氧化起催化作用,以减少油料的氧化变质。
