Research on Microwave Drying Process of Carrot under Different Humidity

Abstract:

To study the effect of different environment humidity on microwave drying process of carrot，moisture of different humidity（30%、50%、70%、90%） flowed the surface of carrot for different time（0.5、1.0、1.5 h）. Humidity and drying characteristic curves were analyzed and the quality of dried carrot was compared. Results showed that，the quality of dried carrot was related to the high humidity maintenance interval and the drying time. In order to improve the quality of dried carrot，longer humidification time and lower humidity of moisture should be selected. It was improved that humidification under 30%、50%、70% for 1.5 h got the better quality of dried carrot.
