• 中文摘要： 本文主要建立一批次乾燥系統之數學模式來模擬在起始期、恆速期及第一減速期物料之乾燥行為。此模式同時考慮物料特性及系統操作條件,例如溼度、空氣溫度及空氣流速等。在模式中引進Nu/sub 0/、Sh/sub 0/及Le三個重要的無因次參數來描述乾燥曲線的行為。文中亦探討物料厚度及空氣流速對羊毛物料乾燥之影響。將此模式在極限操作條件下之結果與Chen及 Pei模式在固定條件下之結果比較來印證所提模式之正確性。
• 英文摘要： A mathematical model was developed for simulating the drying behaviors of materials during the initial rate period, the constant rate period, and the first falling rate period in batch drying system. The developed model was considered in regard to both the characteristics of material and the dynamic characteristics of material and the dynamic changes of operational conditions for the system, i.e. humidity, air temperature and air flow rate, etc. Three important dimensionless parameters values Nu/sub 0/, Sh/sub 0/ and Le were introduced to describe the characteristics of drying curves. The effects of material's thickness and the flow rate of the inlet air were also studied for wool. The proposed model was identified by comparing the results under the conditions of limiting operation with those of Chen & Pei's model under the conditions of constant drying.
