稻谷真空干燥工艺参数对糙米爆腰增率的影响
|
摘要
采用二次正交回归旋转的设计试验方法,建立了以糙米爆腰增率作为目标函数的数学模型,旨在为有效地确定稻谷真空低温薄层干燥的最佳工艺及真空干燥机的结构设计提供参考。实验研究表明:干燥时间、真空度和干燥温度是影响稻谷真空干燥糙米爆腰率增加的重要影响因素,3因素影响的先后次序应为干燥温度、干燥时间、真空度;干燥温度和干燥时间正相关于爆腰增率,而真空度与之呈负相关。
In this paper,a mathematical model for the target function on the crackle ratio incrementof brown rice is established by using the method of quadratic orthogonal rotation design. In order to determine the best drying process and the design of vacuum dryer for rice low temperature vacuum. Studies have shown that drying time,vacuum pressure,and drying temperature are three most important factors for the crackle ratio increment affect of paddy rice vacuum drying,affect the order as the drying temperature,drying time,vacuum pressure,and the drying temperature and drying time and the crackle ratio increment were positively correlated,and vacuum degree and a negative correlation.
