Diseño y Construcción de un Secador por Fluidización para Deshidratación de Trigo (Triticum vulgare)

Abstract

The objective of this thesis is to design and build a fluidized dryer for the dehydration of wheat (Triticum vulgare), making the material suspended, swirling with it, forming the fluidized bed. The equipment is designed and built with a cylindrical drying chamber made of AISI 304 and 430 stainless steel, being a batch type discontinuous dryer, with dimensions of: 70.0 cm in height and 19.6 cm in diameter, multiple burners that heat air, circulated through a tube (sweet iron), driven by a 3600 rpm veterol, a manual sensor to regulate the temperature, and a digital time controller that controls the temperature and time. The analyses for the design and construction of the equipment were carried out in the Chemistry Laboratory of the Faculty of Sciences School of Chemical Engineering. The fluidization dryer operates at a temperature (60 C), with a capacity (10 Kg/h), at a NRe (711.22 turbulent regime) product of swirling, with a fluidized bed height of 12cm, drying at a speed (4.478 Kg/m2h) in a maximum drying time = 5 min per Kg, reaching a humidity of 12.7% b. s. obtaining a yield 10 times higher than that of trays, taking into consideration the physical and chemical properties of wheat, established by the standards, satisfactorily fulfilling the proposed objectives.
