Effect of Kernel Moisture Content to the Result of Bare Hand Threshing of Corn Ear Interval

Abstract:

Corn is one of the world's three major grain crops, corn harvest is an important way to improve the yield of corn, and threshing is an important post-harvest. Therefore, the study of threshing corn ear is particularly important. This article is to find the best threshing moisture of corn ear and the method of reducing the loss of kernels damaged, experiment on Xun Dan 20 and Ning Yu 524 two varieties of corn ear kernels are carried out, arrange in the order interval, and different varieties of seed corn ear conducted bare hand threshing test in different moisture content. Then MATLAB software for data processing and analysis, obtain the effect of moisture on the threshing of corn ear. The conclusions shows that, whether corn ear in which moisture content, the contact force needed on the initial part of threshing ear kernel is larger than the terminal part of the threshing ear kernel. In contrast, the threshing rate on the terminal part of the threshing ear kernel is larger than the initial part of threshing ear kernel in the threshing rate. Too low or too high moisture content is not easy to threshing corn ear, the ear is suitable for threshing kernel when the moisture content of ear kernel at 12%~18%.Ear varieties has a great influence on threshing contact force needed.
