Methods of Grain Drying

So far, drying systems have not been classi‡ed systematically. However, drying methods can be broadly classi‡ed on the basis of either the mode of heat transfer to the wet solid or the handling characteristics and physical properties of the wet material. †e ‡rst method of classi‡cation reveals dierences in dryer design and operation, while the second method is most useful in the selection of a group of dryers for preliminary consideration in a given drying problem.
