METHOD OF PERIODIC REMOVAL OF EXCESS MOISTURE FROM GRAIN MASS AT BULK METHOD OF STORAGE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC A01F25/08 

FIELD: agriculture.

SUBSTANCE: method of periodic removal of excess moisture from the grain mass at a bulk method of storage consists in the fact that the periodic removal of excess moisture from the grain mass is carried out throughout the volume simultaneously in successive cycles changing in the direction by air flow of different temperatures. The device for implementing the method is a system of active ventilation with the channels extending through the volume of the grain mass. The channels consist of at least one or several interconnected cylindrical perforated air-ducts, at that the air-ducts are placed in the mesh sleeve mounted with clips along its length. At the ends of the channels the inflators are installed, which are connected directly to the channel if there is one channel in the system, or through the collectors if the system consists of several channels. For periodic alternate supply of airflow of different temperatures into the channels there are air dampers mounted in the connecting element in front of the inflators.

EFFECT: invention provides avoiding excessive drying of grain mass throughout the volume and increase in efficiency of the process of active ventilation.
