Diseño Concurrente de una Secadora Vertical Intermitente para Arroz.

Abstract

The present work reflects the concurrent design of a vertical intermittent rice dryer whit a capacity of 20 ton and a reduction of 2% per hour, in which the fundamental design parameters are: drying temperature, grain humidity and pressure losses among others which influence directly on the efficiency of the machine. There the concurrent design intervenes upon carrying out the theoretical design and verifying it with different CAD programs which permit to conduct an analysis of the designed elements and compare the results, reaching an acceptable error margin taking these data as valid for the equipment design. To innovate the existing rice drying machines a scale prototype has been constructed in order to carry out experimental test determining the optimum drying time reducing the humidity percentages to acceptable values for silo storage. The experimental results show a great constructed prototype efficiency and stimulate further construction and improvement of such drying systems. Complementary different elements and necessary machinery such as: vibrator transporter, bucket elevators, straw dryer, double-ear fan and air ducts to complete the drying system and optimize the process, were selected. With the construction designs of the different constituting elements it impossible to carry out a correct designed machine manufacture optimizing manufacturing material and time.
