Calculation of Moisture Content and Drying Rate during Microwave Drying

Abstract

Convectional dryerswork at high temperature and usually lead to loss of quality for sensitivebiomaterial products (especially in nutrition). In this way the researchersfound the microwave power more effective and suitable for drying processes. Someof microwave drying advantages include the following: short drying time, highquality of product, low operating temperature, flexibility in producing widerange of products and easier process controlling. The article calculated themoisture content and drying rate during drying process. Microwave power, holdertray speed, dimension of samples, irradiation time were considered; under theseconditions experiments were done and the results show that microwave method hasmore advantages as comparing with convectional methods.

“…These studies have different directions. Some of them focus on the design of technical equipment [14; 15], others investigate drying methods and their combinations [2; 8-11; 16], examine the effect of different pre-treatment methods [16][17][18], investigate the influence of different drying parameters and conditions [7; 12; 15; 19-25], and improve mathematical models [26][27][28].…”
