When a drying step is needed, the engineer must choose the most adequate equipment, which must fit into the whole process. He must compare the advantages and disadvantages among the many available choices considering both technical and economic aspects. Some authors describe the dryer selection. Even though each author develops his or her own dryer selection, a general guideline in their dryer selection models may be identified. Every author establishes a query or a flowchart by which through its inquiry we are guided to the most appropriate equipment. From a brief review, one may notice two basic procedures for dryer selection: analytical by which a series of process decision eliminates the inappropriate equipment to the problem solution, leading to the best solution; numeric - by which each equipment is awarded a sum of points according to its adequacy to the problem solution, the solution showing the highest sum is assumed the best solution. In this paper the results achieved in a new dryer selection was conceived by ALONSO [2].
