中文摘要 | 本文主要在探討大氣溫濕度對低溫通風後之貯穀穀層間穀溫變動之影響。本試驗 貯存稻穀之圓筒高度3.5公尺,直徑0.35公尺。低溫通風後貯穀初溫介於16.6℃∼17.9℃, 靜置回溫試驗設定的條件為大氣溫度與貯穀初溫之溫差介於8.0℃∼14.7℃,大氣濕度介於 70.2%∼81.0%。當環境溫度與貯穀初溫之溫差愈大時,貯穀回溫速率愈快。同時環境溫度與 貯穀初溫之溫差愈低時,大氣濕度對貯穀回溫速率影響較明顯。因此低溫通風後的貯倉稻穀 仍須注意穀溫受環境溫濕度變動之影響。另外由標準迴歸係數值指出回溫速率受到環境溫度 與貯穀初溫之溫差影響較穀層高度為大。靜置回溫速率之逐步迴歸公式為: 回溫速率=(0.013)×(環境溫度與貯穀初溫之溫差)-(0.00017)×(穀層高度) -0.0058 |
英文摘要 | The objective of this study was to study the effect of ambient air on the warming rate of stored paddy after chilling . The size of the experimental ailo was 3.50m in hight and 0.35m in diameter. The initial temperature of the stored paddy after chilling was kept between 16.6℃ and 17.9℃ in this study. To study the warming rate of stored paddy after chilling process, the temperature difference between the ambient air temperature and the initial paddy temperature after chilling was kept between 8.0℃ and 14.7℃ and the ambient air humidity was kept between 70.2% and 81.0%. The warming rate increase with the increasing of the temperature difference between the ambient air and the initial temperature of the stored paddy. When the temperature difference between the ambient air and the initial temperature of the stored paddy is small, the ambient air humidity will significantly control the warming rate. Therefore, the influence of the ambient air humidity on the temperature of the stored paddy after chilling should be considered. The standard regression coefficients indicate that the temperature difference between the ambient air and the initial temperature of the stored paddy have more significant influence on the warming rate than the paddy depth. A step-by- step regression equation for measuring the warming rate of the stored paddy after chilling was developed as following: warming rate=(0.013) x (temperature difference between ambient air and initial temperature of paddy) - (0.00017) x (paddy depth) - 0.0058 |
