The developed storage system involves the use of a convective coolant flow in two directions: centralized - for continuous removal of moisture from the surface of bulk products and the creation of necessary microclimate conditions and local – for excitement and continuous updating of raw materials layers when removing moisture to the surface. Such a granary scheme with active ventilation by the convective flow of the coolant makes it possible to preserve the basic properties of the product with minimal losses over a long period. The local method of cooling is achieved using special pulsed pneumatic single bubblers, which are placed on both sides of the pallet with products, placed in bulk, opposite each other. As a result of the interaction of counterpropagating pneumatic waves and their superposition, standing waves are formed, which transfer kinetic energy both in the longitudinal and in the flows, which in turn touch the grain mass. Under such conditions of storage of the grain mass, the caking and activation of undesirable microbiological processes are practically excluded. This system does not provide for the use of sufficiently metal-consuming and energy-intensive mechanical means of affection of grain products; therefore, it is distinguished by high reliability and competitiveness, which was confirmed by the results of implementation in farms. The use of this method allows you to quickly reduce the initial temperature of the batch of grain, and thereby prevents losses that result from the storage process.
