谷物干燥机烘干温度对种子发芽率的影响分析

针对谷物干燥机烘干后的种子存在着发芽率降低的问题,本研究对影响种子发芽率的诸多因素进行了归纳,对温度参数进行检测,试验前后的种子发芽率,温度参数对烘干种子发芽率的影响进行了研究,提出了一种谷物干燥机烘干温度分析方法,利用合理布置的比对温度传感器,对谷物干燥机内的实时温度进行了监测。研究结果表明,烘干后种子发芽率降低的主要原因是谷物干燥机的机配温度传感器存在误差,影响烘干温度的准确性;谷物干燥机热风道结构的设计,温度最高位置会导致相邻谷物温度超差;谷物干燥机内温度分布不均匀导致局部谷物温度超差及机配温度传感器在谷物干燥机内的布置不合理,未反应机内最高温度。

Quality appraisal of the seed grain dryer

Aiming at the drying seed germination rate is decreased after dried by seed grain dryer,the various factors that affecting the seed germination was summarized,the temperature parameters and the seed germination after drying were tested,the influence of temperature parameters to the dried seed germination was analysed.an analysis method of the grain dryer drying temperature was proposed,the logical layout temperature sensor was used,and the real time temperature in the grain dryer was monitored.The results showed that,the main reason of seed germination decreased after drying are these the temperature sensors in the machine have deviation,affect the accuracy of drying temperature;because of the hot air channel structure design,the highest temperature point will leading the adjacent grain temperature increased;uneven distribution in the machine led to local grain temperature higher than other parts;unreasonable temperature sensor arrangement,can not feedback the real highest temperature.Through the boot test of grain dryer drying the seed,detected the temperature parameters,compared the seed germination after drying,to analysis the effects of temperature parameters to the dried seed germination.
