For example, air outlets are vertically aligned to each other in these kinds of grain dryers, and an aspiration turbine is connected with each one of said air outlets, which aspirate air used in the drying process and expels it out.
2. Description of the Prior Art.
As anybody having skill in the art knows, grains do not have to be stored if they are not dry, being allowed certain percentage of humidity, for example, less than 15~.
as a limit to consider said grains dry, this value depends on several factors, such as the climatic conditions of the corresponding region. In artificial grain drying techniques, the air expelled by drying machines by means of its turbines includes a lot of particles in suspension, which affect the environment next to the dryers. This situation generates conflict zones because of the contamination of the atmosphere, specially when these machines are disposed near houses, offices, ways, just to mention some examples selected between diverse concrete examples.
In order to solve such disadvantages, the air used during the process of drying of grains is has to be filtered or to purified in an efficient and safe way, so as separating the particles in suspension. The disposition of the present invention has been developed with that purpose; the structure of the disposition of the present invention presents a conformation that lets to reduce considerably the solid concentration in the air expelled by the dryer.
To achieve that effect, it was taken on count the necessity to satisfy two essential aspects, such as to catch the greater amount of particles possible and to avoid dryer's turbines to lose efficiency. In this last aspect, it is possible to indicate that the efficiency losses of dryer's turbines reduce the drying air volume and, consequently, said losses reduce the production measured in ton/hr (ton/hour), is to say tons per hour, of dried grain.
Because of it previously explained, it is emphasized that in the proposed embodiment, as the following description will be make evident, it have been contemplated and adjusted each one of the dimensions of the parts that compose it, having achieved in that way beside the point satisfactory results.
