Optimization of variable-temperature drying process for high moisture wheat based on response surface methodology
To optimize the variable-temperature drying process of high-moisture wheat,reduce energy con-sumption and drying time,and enhance the post-drying quality,the effects of stage Ⅰ temperature(40-60℃),moisture conversion point(15%-19%),and stage Ⅱ temperature(45-65℃)on the drying rate,post-drying quality(color difference,hardness,sedimentation value,and seed vigor),as well as mi-crostructural changes of high-moisture wheat were investigated.The results showed that the optimal varia-ble-temperature drying parameters for high-moisture wheat were a stage Ⅰ variable-temperature of 46℃,a moisture conversion point 16%,and a stage Ⅱ temperature of 56℃.Under these conditions,the high-moisture wheat achieved a comprehensive score of 0.826,indicating good drying quality.The average error between the experimental and predicted values from the response surface methodology was 1.67%.This study provides a theoretical reference for the variable-temperature drying technology of high-moisture wheat.
