Process and Equipment to Deactivate Grains

EQUIPMENT TO DEACTIVATE GRAINS which encompasses a basically cylindrical body with vertical displacement of the grains by gravity, characterized by the fact that it presents:

• a) An antechamber (01) disposed on the upper part of the equipment;
• said antechamber provided by side inspection lids (03) and an inverted conic trunk base equipped with a plurality of parallel tubes (02), which are trespassed inwardly in two sections;
• b) An entrance rotating valve (11) triggered by a controlled motor (12) arranged on the base of the antechamber (01);
• c) A condenser (08) connected to the antechamber (01), said condenser (08) equipped with a steam ejector (09) and an escape condenser channel (10) that releases the condensed steam;
• d) A heating cylinder (13) interconnected to the entrance rotating valve (11), said heating cylinder (13) presenting, in the internal region, the disposition of a heating chamber (18) equipped with diametric chutes (14) arranged in a misaligned way, at different angles and levels, of walls in inverted “V”, said heating chamber (18) presenting in the lower part a perforated plate (15) for the escape of the steam which is injected through the steam entrances (16) on the heating cylinder wall (13) under the diametric chutes (14);
• e) Base chutes (17) arranged in ramps and positioned below the diametric chutes (14), said base chutes (17) connected to the multiple rotating valve of the base (19) and triggered by a controlled motor of the base (20);
• f) Cylinders of the heated dishes (21) arranged below the multiple rotating valve of the base (19), said cylinders (21) equipped with an upper heated dish (22), consisting of two metallic disks (23), away from each other, in which spacing (24) steam is introduced, presenting a revolving shovel (25) that spins according to a vertical axis (38) triggered by a motor (39) that drags and mixes the grains by pre-drying chambers (04), including an opening (26) provided with discharge tap (32) for the discharge of the grains over a second heated dish (27) and a third heated dish (28);
• g) escape lower rotating valve (31), triggered by a motor controlled by the lower rotating valve (32), which keeps the vacuum in the pre-drying chamber (04) and regulates the output flow of the grain as well as the time of permanence in said pre-drying chamber (04).

PROCESS TO DEACTIVATE GRAINS USING THE EQUIPMENT CLAIMED IN 3, characterized because it involves the stages of:

• a) Pre-heating the grains in the ante-chamber (01);
• b) The grains are displaced by gravity to the heating chamber placed inside the heating cylinder (13);
• c) The grains are displaced through the heating cylinder (13) through the heated chutes (14), promoting the homogeneous heating and undergoing a moisturizing process as a result of the steam that comes out of the perforated plates (15);
• d) The grains flow through the base chutes (17) to the multiple rotating valve of the base (19), which regulates the flow of the grains;
• e) The grains go to the cylinders of the heated dishes (21) falling over the upper heated dish (22), with a revolving shovel (25), which drags and mixes the grains in the pre-drying chambers (04) and forwards them to an opening (26) over the second heated dish (27), where it undergoes pre-drying under negative pressure, after the opening (26) with the grain mass being deposited over a third heated dish (28);
• f) The grains move on for cooling and/or final drying.
