Along with the decision to install a grain dryer, comes the need to decide on the type of dryer to install. Grain dryers come in three broad categories; static batch dryers, recirculating batch driers, and continuous flow dryers [continuous- flow dryer]. The decision as to which is the best type for any particular farm, will depend on a number of factors and it is probably easier to consider the characteristics of each drying system and then apply them to the needs of the particular farm.
