After deep processing, it can be used to make beer. The husks of the cobs can be used to weave daily handicrafts. Before processing corn, the corn kernels need to be peeled off the inedible corn cobs to facilitate subsequent operations. Although most corn threshing work is currently done by mechanical extrusion, since most of the extrusion uses dry corn, the finished product after threshing contains a large amount of corn cob fragments and residues.
