微波—热风联合干燥法在竹笋湿法制粉中的工艺优化
Process Optimization of Microwave-hot Air Combined Drying for Wet Grinding of Bamboo Shoots
摘要
Abstract
The influence of microwave power density on the drying characteristics and qual-ity of bamboo shoots powder,as well as the influence of hot air temperature on the afore-mentioned characteristics and quality,was studied.Orthogonal tests were carried out for the microwave-hot air combined drying method,with the influence of microwave power density,water content at the conversion point,and drying temperature of hot air.Follow-ing the identification of the optimal drying process,an analysis was conducted to evaluate the quality of the subjected bamboo shoots powder samples.The optimal conditions for the microwave-hot air combined drying method for processing bamboo shoots powder are determined to be a microwave power density of 11.2 W/g,a conversion point water con-tent of 5 g/g,and a hot air temperature of 95℃.Under these conditions,the drying time of the produced bamboo shoots powder is significantly shortened while maintaining the color and luster,reducing the browning degree,and preserving all the nutrients and physi-cochemical indexes.关键词
