GRAIN IN CAPACITY STORAGE METHOD IN THE CONTROLLED GAS ENVIRONMENT AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC A01F25/14 

FIELD: agriculture.

SUBSTANCE: invention relates to the agricultural products, mainly grain, storage technology. Grain storage method involves the use of capacity, which is installed in the container body at the bottom. Capacity is made in the form of a skirt of elastic material, on outer side covering the frame of hollow annular polyethylene rims and vertical hollow aeration polyethylene tubes. Together with the skirt container is tightly closed on top with a plastic lid in the shape of a dome. In the center the lower annular rim is connected to a small hollow ring by means of radial beam polyethylene tubes with holes. Skirt bottom central part is made with a sleeve for the products unloading, located coaxially with a hole in a small hollow ring. Attached to the skirt middle part annular rims are made with fitted with the nozzles system holes. Via the air duct pipe the upper annular rim is connected to the reversing switch with impeller for the cold compressed air supply and performance of the forced air circulation in the skirt with the grain material in height. Air duct pipe is also connected to the second pipe with a reversing switch and a vacuum pump for the atmospheric air removal. At the top the polyethylene cover has a side loading opening with a sealing cover, and is also equipped with the low pressure relief valve and the air pressure sensor. Grain material purging is carried out depending on the its breathing intensity at a relative humidity of air, set in the range of 60–65 %, the average speed of not more than 0.1 m/s, until the grain specified final moisture content achievement, not exceeding 13–14 %.

EFFECT: this method and device for its implementation allow to eliminate the grain losses from the mold formation during storage while maintaining its appearance.
