苜蓿段长度对干燥速度与悬浮速度影响的试验

Experimental Study on the Effect of Alfalfa's Length on Drying Rate and Floating Velocity

在薄层干燥试验台上进行薄层干燥试验,研究不同长度苜蓿段在压扁和未压扁两种情况下含水率及干燥速度随时间的变化规律。并在悬浮试验台上做悬浮试验,研究苜蓿段长度对悬浮速度的影响。

Thin-layer drying experiment of alfalfa was done on thin-layer drying experiment table to study different lengths of alfalfa＇s moisture content and drying rate changing with the time under the two circumstances of crushed stem and the uncrushed stem. At the same time the floating experiment was done on the floating experiment table to study the effect of alfalfa＇s length on the floating velocity to provide basis for choosing technical parameters during alfalfa＇s drying.
