Abstract: This study was aimed to optimize the belt drying process conditions ofChuan-XiongConcrete. On the basis of the single factor experiment with drying temperature, feeding speed, drying time as three main variables and the transfer rate of ferulic acid as variable, the optimization of the belt drying process conditions ofChuan-XiongConcrete was identified using Box-Behnken Design. The results showed that the optimal drying parameters were as follows. The feeding speed was 1 kg·h-1. The drying temperature was 95℃. The drying time was 90 min. The transfer rate of ferulic acid was 95.48%. Three verification experiments were taken under these technological parameters. And the average transfer rate of ferulic acid was 95.71%, which was close to the predicted value of the model. It was concluded that the belt drying process of Chuan-Xiong Concrete was steady and feasible, which can be used in the drying process ofChuan-XiongConcrete.
