Abstract

Based on a microwave drying system，automatically and continuously regulating microwave power and temperature control, a drying model composed of three different temperature and power controls was used to investigate the potato chips. After analyzing the drying quality and energy consumption of the three drying models, a good microwave drying process for potato chips was found. The research showed that the microwave drying without temperature control was easy to overheat in the last drying stage and made the product burnt. However, the optimal temperature control effect and product quality could be obtained by combining the variable microwave power with the feedback temperature control based on the scheduled power distribution. Moreover, in the microwave drying process, taking the temperature control scheme of variable power could save about 35% energy consumption than fixed microwave power.
