黄秋葵热风干燥工艺研究
Study on drying process by hot air for okra
摘要
Abstract
In order to seek the further processing technology of Okra after large scale planting,the drying process was researched by using the GZ-1 hot air convection drying apparatus.The specific energy consumption factor was presented from the formula of energy consumption,as an evaluation factor of energy consumption.The effects of different drying air temperature,wind speed and the layer number of laying on drying rate were tested.The drying rate,energy consumption,color and the change of polyphenols content were taken as the evaluation indexes.The optimum hot air drying conditions were temperature 80 ℃,double layer laying,wind speed 1.2 m/s at first,then reducing wind speed to 0.8 m/s when the wet basis moisture content is less than 53％.Under these conditions,the better color index,higher flavonoids and polyphenols content and higher energy efficiency were obtained.关键词
