Study of resistance characteristics during ventilation in corn
The changes of resistance characteristics in corn under suction and push-in ventilation modes were studied by the testing device of ventilation performance parameter,the results showed that the surface wind speed of grain was positively cor-related with the resistance of unit grain layer and the resistance of net,and the polynomial quadratic function has higher fitting degree.The ventilation uniformity of corn is positively correlated with the grain layer thickness.The thicker the grain layer,the better ventilation uniformity.
