ANALYSIS OF LABORATORY MODEL OF CORN RESERVOIR DRYER WITH FIXED BED
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 10
Abstract
Drying of agricultural products is one of the most important steps in whole production process. In order to ensure the safety of final product storage and increase storage life, drying agricultural products is necessary. The purpose of this study is to evaluate the function of laboratory dryer with fixed bed. To achieve this goal, some experiments were performed at different temperatures, heights and initial moistures. The experiments at five different temperatures (70, 80, 90, 100 and 110˚C) and the height of product in the reservoir in four different levels (20, 40, 60 and 80 cm) were performed and the effect of temperature and height of product layer on the duration of drying was investigated. Furthermore the effect of these factors on changes of water content was checked. The results showed that by increasing the inlet air temperature, duration of experiments decreases and gradient of water content changes increases while by increasing height of product layer, duration of experiments increases and gradient of water content changes decreases.
