Diseño de un secador de bandejas para la deshidratación de plátano en la Parroquia Veracruz del Cantón Pastaza.

Abstract

This research is intended to design and a plantain tray dryer for the dehydration of plantain in Veracruz parish from Pastaza. In this aim, a silulation of drying procedures was carried through the tray dryer from existent lab. Which led us to determine a 50 oC dryng temperatura curve, where the equilibrium wetness accounted for 0,04 kg wáter/kg dried solid and the critica wetness accounted for 0,371 kg wáter/kg dried solid. Thus, these data led us to the further equipment measuring for a 10 kg plantain charge. The dryer consists of a rectangular chamber of 0,92 m high, 0,6 m length, 0,53 m wide, which will have 5 trays of 0,5 m length and 0,4 m wide. The required heating resistance accounts for 880,8 W power and the air circulation into the chamber will be generated by a 1700 rpm ventilator. Glass wool will be used to obtain a 44337,41 W heat and it is advisable to keep in mind hte observance of temperatura at which the plantain must be dried.
