一、引言 种子烘干是种子加工作业中的重要环节。在设计种子烘干机时,必须用试验的方法测得该种子的干燥曲线;在使用种子烘干机时,又必须根据种子的不同初始状态确定最佳工艺参数,以便准确地控制烘干时间获得最佳的干燥质量,最低的能量消耗。因此,在设计和使用种子烘干机前都必须进行大量的试验研究工作。由于在进行烘干试验过程中,要随时监测大量的数据;同时,每进行一次试验都要对工艺参数(如温度、风量等)进行调节, I. Introduction Seed drying is an important part of seed processing operations. When designing a seed dryer, the drying curve of the seed must be measured experimentally. When using a seed dryer, the optimum process parameters must also be determined according to different initial states of the seed in order to accurately control the drying time Get the best dry quality, the lowest energy consumption. Therefore, a great deal of experimental work must be done before designing and using seed dryers. Due to the drying process in the test, to monitor a large number of data at any time; at the same time, each test should be carried out on the process parameters (such as temperature, air volume, etc.)
