The control system of the aeration and preservation of stored grain by measuring gas

摘要

It is described a control system of the aeration and preservation of stored grain by measurement of gases, the object of this privilege of the invention.Aims at solving the problems described in the state of the art through a system equipped with a tube sampler (10) of gas fixed in the roof of the silo bulk carrier through a coupler got to(11), and is composed of a perforated stainless steel tube (12) wrapped in a particulate filter (13) to clean the air aspirated from the powder contained in the silo.Directing the air through a flexible tube (20), and a metal housing (40) containing exhaust gas sensor (41) and (30).It carries out the measurement of samples of different types of gases generated in the environments of storage of grain, in order to verify the presence of CO2 (carbon dioxide) in these environments.Since CO2 is a by-product of respiration of microorganisms. Ensuring an anticipation in decision-making in the aeration of grain or other measure that is necessary to up to five (5) weeks.
