中文摘要 | 此研究用以探討循環式乾燥機應用於稻穀乾燥之作業成本,並以數學公式量化各 影響因子。乾燥機作業性能資料則來自官方之性能測定資料。乾燥機之售價與容積重為包含 四次方之多項式關係。10 噸以上之大型機器,SS 廠牌之乾燥作業成本為 480-550 元 / 噸 ,SC 廠牌之成本為 440-730 元 / 噸。 單項成本方面,利息、維護與油電成本占總成本之 比例不因大型化而改變。折舊成本之比例因大型化而增大,勞力成本之比例則相對減低。乾 燥機之售價以每噸容量固定補助之方式,約可降低作業成本約 25%。由容基重與售價之關係 ,國內循環式乾燥機之大型化極限以 30 噸左右為合理範圍。利用量化各影響因子之成本分 析公式,可合理化評估作業成本,以提供代乾中心濕穀收購之合理計價。 |
英文摘要 | The operating costs of rice circulating dryers were studied in this study. These factors affecting the operating costs were quantified by mathematical equations. The performance data of dryers were adopted from the official information. For the dryers that its capacity higher tan 10 tons, costs were from 480 to 550 NT$/ton SC-type dryers, and from 440 to 730 NT$/ton for SS-type dryers. As the increase of capacity, the ratio of interest, maintenance, and oil costs were not affected, the ratio of depreciation cost was increased, however, those of labor was decreased. The cost would reduce 25% due to the effect of subsidy of purchasing costs by goveronmental policy. the capacity of largest dryers were limited at nearly 30 tons from the analyisis of the relationships between the capacity and purchasing price. The cost equations of this study provide a reasonable way to evaluate the drying cost of wet grains for drying centers. |
