ACCELERATED DRYING SYSTEM OF VOLUME GRAIN BY CLOSED AIR CIRCUIT WITH CONTROLLED HEATING, MAINTENANCE AND COOLING STEPS

摘要

represented by an inventive solution in the agribusiness sector, notably in the rice processing sector and more specifically in a closed-circuit batch volume accelerated drying system, equipment and process of rice grains, whose inventive concept is to make it viable The accelerated drying of grains at temperatures above the glass transition temperature of the grain, without compromising the quality of the obtained dry grains, therefore, in contradiction to what is known in the literature regarding grain drying, and to make this objective feasible, accelerated drying process is conceived, which comprises as main steps the controlled heating, maintenance and cooling of the grains, which in turn is operational only with the use of a drying equipment composed of operational devices for: grain drying, transport and rice circulation, air circulation affecting the grains must be dried; heating and cooling air circulation drying air, drying air relative humidity control and even operational control of the devices.
