摘要
在连续式辣椒干燥机上进行了板椒干燥实验,研究热风温度对辣椒干燥规律的影响,达到保持辣椒干燥品质、提高干燥速率、减少干燥时间、节省干燥成本的目的。通过改变干燥机中循环热风的温度,测量不同时段辣椒的质量、色泽等参数,分析不同热风温度下辣椒的色泽、干燥的均匀性和干燥速率的变化特点。实验结果表明:随着热风温度的升高,辣椒的干燥速率逐渐加快,表面的明度与红色度逐步升高,而干燥的均匀性则逐渐降低。综合考虑辣椒的干燥效率和干燥品质,热风温度采用65℃辣椒能够保证辣椒良好的色泽和均匀性,并能达到较好的干燥速率。
Drying capsicum on continuous dryer and research the temperature of hot air influence on capsicum,in order to keep the capsicum quality,improve the drying rate,reduce the drying time,save the cost of drying.Changing the temperature of hot air and measure weight,dry uniformity and drying rate to compare the change characteristics.The experimental results show that,with the rise of air temperature the drying rate was accelerated,surface brightness and red degree was accelerated,while dry uniformity was reduced.Considered the drying efficiency and quality,60℃ and 65℃ of temperature can ensure capsicum color and drying uniformity,and can achieve good drying rate.
