摘要: 对罗非鱼片进行了热风薄层干燥实验,通过实验数据建立了罗非鱼片的热风干燥的水分比与干燥时间关系的数学模型,根据建立的模型进行了拟合检验,结果显示模型的预测值与实测值拟合良好。此外,还研究了罗非鱼片热风薄层干燥过程中的能耗特点,结果表明,热风薄层干燥罗非鱼片的单位能耗降湿量最低为423.4g/kW·h,最高为1147.7g/kW·h。鱼片越小,每批干燥量越少,则单位能耗降湿量越大。

Abstract: Thin layer hot-air drying of fresh tilapia fillets at different temperatures was investigated. Meanwhile the suitable mathematical model which can be used to describe the relationship of moisture ratio and drying time was established in this paper. The proof test results showed that the model was good due to the predicted values consistent with the observed values. In addition, the characteristics of energy consumption of the thin layer hot-air drying of tilapia fillets were also researched. It wasfound that the minimum and maximum moisture removal quantity per energy consumption was 423.4 g per kilowatt and 1147.7 g per kilowatt, respectively. The fewer quantities of fillets during drying were, the higher moisture removal quantity per energy consumption was.
