Avaliação das unidades armazenadoras de arroz no município de Alegrete – RS

Abstract

Grain storage is a very important step in production, because during storage there are several chemical reactions that degrade the stored material. The procedures that aim to update the activities of storage and conservation of agricultural products have been one of the main demands of the related sectors. This work consisted of the evaluation of 12 storage units in the municipality of Alegrete – RS. The study was carried out through visual inspection of the storage silos and for ventilation systems the evaluation was carried out by measuring wind speed and flow. Of the evaluated storage units, all have vertical silos and most of them have a thermometry system. The flow rates show that more than half of the units have air mass flow values within the established values and all have an electrical resistance humidity meter. Therefore, most of the units meet the minimum standards established for grain storage. For units that have obtained any value below the table, it will be communicated to carry out the appropriate procedures to correct the problem.
