Desenvolvimento de um secador de grãos de leito fixo em escala reduzida

Abstract

With the increase in technologies in the post-harvest area, it is necessary for the Agricultural Engineering course to have subsidies, such as equipment, that can simulate activities carried out at an industrial level, providing students with knowledge about their functionalities, and preparing them for the job market with a broader view of these equipment. In this sense, the present work aimed to build a fixed-bed grain dryer on a reduced scale using low-cost, yet functional and efficient materials. In this work it is possible to visualize all the steps that were used for its development, such as projection, construction and validation. Once construction was complete, the equipment was put to the test, resulting in data such as air flow, drying temperature and drying efficiency. However, after the completion of this work, the equipment will be donated to the Agricultural Engineering course at the Federal University of Pampa to help teachers in the area teach their practical classes and make them more dynamic. In addition, the equipment will also assist in the simulation of product drying tests, providing students with a better perspective of the operating principle of a grain/seed dryer, also enabling the development of research and course completion work, using the equipment.
