Patent attributes
Grain dryer of the type comprising a vertical main structure consisting of a central body through which the grain to be dried passes, a front hot air intake chamber and a rear used air outlet chamber, being that the main body has in its upper part an entrance from where wet grains are loaded, underneath which there is a loading hopper that communicates with the central body, wherein the grain descends along the central body within which it is dried during its fall by a flow of hot air that passes through the mass of grain, finally exiting through a discharge hopper arranged at the lower end of the dryer, the dryer of the invention being characterized in that it allows to significantly reduce the energy consumption in order to obtain a better quality of grain and a process much faster than conventional ones due to the arrangement of one or more preheating chambers without extraction of moisture from the grain.
