Drying temperature significantly affects the drying time and drying rate. For example, straw with initial moisture content of 25% lost its 38.6% of water when drying in 60 ° C after 274 seconds, while in 120 ° C, 45.9% of the water will be removed after 153 seconds. Because temperature difference is the main driving force of straw drying, so drying in a higher temperature is needed to remove moisture more thoroughly. As can be seen from Table 2, the final moisture content is 6.3% for drying in 80 ° C, and only 1.1% in 120 ° C. |
