Abstract
Because of the increasing demand of corn by‐products the starch industry processes larger quantities of corn. The increasing use of combine‐harvesters and hot air dryers set the problem to find out conditions which do not alter the intrinsic value of the kernels and to define new quality criteria. An experimental research programm with a laboratory pilot plant gave the following main results:Preliminary storage conditions before drying affect the corn quality. When corn is dried in one stage drying affects the starch yield. Classical commercial gradings are not sufficient to estimate the wet‐milling properties, and have to be extended by physico‐chemical tests.
