中文摘要: 采用变压差组合干燥技术对北冬虫夏草子实体快速干燥。以水分含量 5 %为终点，研究梯度干燥的起始温度、 变压差干燥的干燥温度、一次脉冲次数、真空干燥时间、二次脉冲次数。最佳工艺条件为：梯度干燥起始温度 45 ℃，每 4 h 升高 5 ℃，烘干约 810 min。均湿 12 h 后，进行变压差干燥。条件为干燥温度 55 ℃，一次脉冲 5 次，真空干燥 40 min，二 次脉冲 5 次。此方法较常压干燥法干燥时间缩短 6 h，干燥后的北冬虫夏草子实体在感官上明显优于常压干燥产品。
Abstract:This study used differential pressure combined drying technology to quick drying the Cordyceps militaris. With moisture content of 5 % as the end point，researched the temperature of gradient drying starting， the temperature of differential pressure drying，the number of first time pulse，the time of vacuum drying and the number of second pulse . The optimum technological conditions was：the temperature of gradient drying starting was 45 ℃，increased 5 ℃ every 4 h，dried about 810 min. Averaged wet after 12 hours，started differential pres－ sure drying. The condition was： the temperature of differential pressure drying was 55 ℃，the number of first time pulse was 5 times，the time of vacuum drying was 40 min，the number of second pulse was 5 times. This method's drying time compared with ambient pressure drying shorten 6 h，dried C.militaris was obviously better then Conventional product.
