Análisis estadístico exploratorio de dos tipos de secado de quinua

Abstract

This paper "Analysis statistical exploration of two types of drying of quinoa" allows performing validation statistical type dryer having a high efficiency, performance in this type of cereal drying (Chenopodium quinoa Willd). Dryer trays and a solar dryer greenhouse were used for the effect; the experiment was conducted with three types of samples, one with shell and other scarified. Quinoa was subjected to drying at three different temperatures 30, 40 and 60 °C into the dryer trays at a speed of air of 1.85 m/s, however in the dryer solar carried out on three different days in which the solar irradiation had an average of 4.64 (kWh/m 2 /d), with the results obtained was performed a linear regression with R 2 between 0.95 to 0.99 being the nearest model Page and Henderson and Pabis. Evaluated the results of the two types of dryers was found having better performance the trays when working at temperatures above 40 ° C. It is suggested to conduct a study of the kinetics of drying of the quinoa with a nutritional analysis of the product after drying as the germination.
