稻穀儲存損耗與單位體積重量變化量測之探討

Abstract

本計畫運用所開發之系統進行穀堆重量連續量測，該系統包括承載平台、重量感測模組與膨脹氣囊。榖包堆疊在榖堆承載平台上，可連續監測榖堆之重量與體積變化，繼而建立倉儲榖稻在不同儲存時間因環境條件變化造成損耗之預測模式與單位體積重量之估算公式，確實掌握榖倉榖堆損耗情形，使公糧管理步上更科學化與合理化的境界。今年度的主要工作將著重在增加測試樣本，以修正損耗預測模式與單位體積重量之估算公式。

Asystem for continuously measuring weight of grain stored in the granary is proposed here. The system consists of platform, AreoJack, and weighing module. The system is designed to avoid an effect of stress creeping. The packs of grain will be put on the platform.The weight and volume will be monitored continuously. The loss of grain due to changes of environmental factors during storage can be predicted. And, the formula for predicting unit volume weight will be established in this study. Therefore, the management for grain storage can be more scientific and reasonable. In Year 2012, the major work will be to increase number of experimental samples and to use these data to modify the prediction model for grain loss as well as the fomula for computing the unit volume weight.
