FIELD: agriculture. ^ SUBSTANCE: several stages of drying are successively installed one after another in the moving flow of the heat carrier as flat oblique oscillating sieves or conic sieves rotating with a constant speed through which a drying object is directed as a flow with a constant or variable speed, constant or variable density and with a capability of controlling the speed and density of the drying object and the heat carrier and the heat carrier temperature is elevated from stage to stage at an equal value. To do that it is passed successively through each stage of heating. It is controlled by means of sensors installed one at a time on the first stages of drying, on the one before the last - two at a time, on the last one - four at a time in equal increments evenly in the volume of the drying stage and on the last three drying stages automatic samplers are installed one at a time on each stage and that supply the electric drive and the automatic control system whose operation is programmed input into the on-board computer and the openings of all the sieves are oval of the same or different sizes and place them on the sieves in parallel rows in equal increments equal to 2-3 lengths of the biggest faction of the drying mixture and the openings of every following row by height is shifted relatively to the previous one at half the increment between rows which is equal 3-4 lengths of the opening and the length of the opening is 2-3 times the size of the longest length of the longest component of the drying mixture. ^ EFFECT: improved quality of grain drying. |
