Diseño y Construcción de un Secador tipo Armario para la deshidratación hasta el diez por ciento de Berro, Espinaca, Zanahoria.

Abstract

It was designed and built a dryer type cabiner for dehydration watercress, spinach and carrots to ten percent, the equipment will be at the Laboratory of Industrial Processes of the Chemical Engineering School, Science Faculty of the Higher Polytechnic of Chimborazo to the academic and practical development of students in Unit Operations. For equipment design, engineering calculations, psychometric charts and laboratory testing were used, in order to acquire data for correct sizing. For the construction and assembly of the equipment was used: drying chamber, fan, electric heater, temperature controller, and six stainless steel trays. Built and assembled the dryer type cabinet, equipment validation tests were performed, resulting in the identification of process variables such as humidity, wind speed and drying time. With an efficiency of 93,36 % and dryer performance of 52,80 % vegetables. The construction of the upright type dryers are useful to preserve the nutrients in food, preventing those not degraded and proliferate by the presence of microorganisms. The dryer type cabinet can be used for dryer vegetables that are raw material in cosmetic and food industries purposes.
