Abstract: The disclosure provided herein is directed to a grain dryer, that dries grains such as soy, corn, rice, etc., that may comprise of three or more grain drying towers capable of being arranged in diverse geometric formats, for example, triangular, square, pentagonal, hexagonal, etc. The grain drying towers may comprise airducts arranged transversally in relation to each other and with each airduct containing multiple openings that may be arranged in each of its six faces. Faces of the airducts have interspaced openings where some regions of the airduct may or may not have an opening.

Abstract: The disclosure provided herein is directed to an agricultural products cleaning machine for cleaning agricultural products, such as grains in general, whereby the agricultural products are thrown against a sieve system with curved sieves in the shape of a volute by a grain transport and elevation system or bucket elevator. When thrown, the agricultural products move along as a spiral curtain which collides with the curved surface of the sieve, promoting the separation of agricultural products from impurities.

Abstract: A tower used to extend the life of the grains in the period of their storage, through procedures of grain humidification, sterilization, cooling, freezing and drying, which can be applied together or separately according to with the need of each particular cultivation, offering a multifunctional tower of high performance and low fuel & energy consumption, low noise and eco-friendly, not contaminating the grains that make the heat exchange with steam.

Abstract: The present invention proposes a drying tower with grain flow in parallel and sinuous in combination with reverse and radial crossed air flows in form of “Z” oblique for the implementation in the drying of grains, seeds, fodder, and fruit. Therefore, the grains are firstly submitted to a first stage of parallel grains flow and reverse crossed air flow in order to standardize the different degrees of humidity of the grains and of their impurities. In a second moment, these grains are submitted to a sinuous grains flow and radial air flow in the form of oblique “Z”. Such implementation in drying processes of grains upgrades substantially the drying time and the energy spent for such process, generating in this way profit for the food industries.

Abstract: High performance grains dryer fed by a heat generating source through hot air stabilizers linked to the drying column and the dryer tower, which is constituted by a series of parallel ducts, between which passes the downstream vertical now of grains, unevenly set in oblique alignment and fed so that each duct that operates as hot air entry presents laterally adjacent ducts that operate as used air exit, causing the appearance of air lows crossed to the right, crossed to the left, concurrent and countercurrent, the adopted air flows varying along the drying tower, decreasing along the same, while the perimeter walls of the dryer are equipped with particles separators that generate air flow to the dryer and separate the particles expelled by the drying process, re-conducting them to the burning in the furnace through return ducts.

Abstract: A high-precision, multidirectional air cross-stream grain drier without gradients comprises a continuous drier (1) with internal paths (2) for the grain stream defined between air ducts that fractionate the drying air stream, forming drying air inlets (3) and air outlets (4) arranged in parallel on either side of the grain flow paths (2) and alternating on different levels in such a manner that air streams from the right and from the left are alternatively and successively applied to the same grain stream column, along its entire path.

Abstract: The invention relates to a V-shaped trough comprising two vertical side walls joined by two converging top walls, said walls being provided with a plurality of openings, thereby making the grain columns between the rows of troughs smaller inside the tower and increasing the sped of drying, since the thickness of the grain columns is reduced, thus shortening the drying time.

Abstract: A measurement pendulum for stored grains mass in which a pendulum type measurer (1) formed by a protection structure (2), holds sensors (3) in its inside that have the direct interface with the outside through one or more transversal passages (4), provided of a porous protection (5) in order to measure the desired variables from the interstitial air that crosses the porous protection (5), and represents the grains characteristics in the outside.

Abstract: Integrated aerator for storage and drying silos installed directly over the silo's grains unloading tunnel (1), which is used for the air captation and using the same for drying and conservation of agricultural products stored in the mentioned silo, this aerator being made-up by a modular structure (2) provided of an inferior opening for air captation (3), over which is positioned a rotor (4) associated to a rotation shaft (5) with rotation bearings (6), a set that is driven by a motor (7), in a form to capture air through the opening (3), and blowing the same through a perimeter structure of shutters (8) and exits (9), which direct the blown air directly inside the silo.

Abstract: A grain dryer has three levels of modulated air chambers; a multi-perforated chamber holding grains which surround all three levels of the modulated air chambers; an intermediate air passage; partition walls and a set of central fans to direct airflow cross-upwardly in an S-shape inside the grain dryer; and an external chamber to exhaust air out to the ambient, minimizing heat loss, and thereby increasing the effiency of moisture exhange between grains and air.
