| 摘 要： | 苜蓿干燥是苜蓿加工的重要环节.利用GZ-1型干燥试验装置,进行紫花苜蓿的薄层干燥试验, 探讨了热风温度、热风速度和初始质量对干燥速率的影响.结果表明,热风温度、热风速度和苜蓿初始质量对干燥速率的影响显著.用多元回归方法和BP神经网络建立苜蓿干燥的模型,并对结果进行对比.结果表明,BP神经网络模型预测的含水率精度明显高于多元回归模型.

| Abstract: | Alfalfa drying is an important process in processing of alfalfa.This research aims at discussing the influence of hot blast temperature,hot blast speed and initial mass on the rate of drying by utilizing GZ-1 drying device to conduct the thin layer drying experiment of alfalfa.The result indicates that the temperature and speed of hot wind and the initial quality of alfalfa had an obvious influence on speed of drying.Through multiple regression method and BP network,we set up a model of alfalfa drying,and m... |
