Description

The invention relates to grain drying devices used in agriculture and in the harvesting system.

The aim of the invention is to increase productivity.

The drawing shows a grain dryer, vertical section.

The grain dryer consists of a bunker 1, ° C of two drying and cooling shafts 2 located under the bunker 1, one pressure chamber 3, located between the shafts 2, two discharge chambers 4 located on the outer sides of the shafts 2, two additional discharge chambers 5, on the one side to the shaft 2, and on the other to the pressure chamber 3. The pressure chamber 3 and the discharge chambers 4 and 5 are divided into two compartments, which together with the shafts form two zones: the upper drying zone and the lower cooling zone B mines 2 horizontal rows placed under d conductive 6 and 7, duct exhausts. The inlet ducts 6 are connected at one end to the pressure chamber 3 patr with the slabs 8, and the opposite ends of the ducts 6 are plugged. The discharge ducts 7 are connected at one end with the discharge chambers 4, and the other end with additional discharge chambers 5.

The drying agent. (Air) enters the layer of grain from the pressure chamber 3 through nozzles 8 and supply rods 6, and leaves the grain layer

5 through the outlet box 7 to the outlet chambers 4 and 5, with both ends of each outlet box 7 open. Due to the fact that the spent drying agent leaves the mines through

0 both ends of the outgoing box 7, its speed can be increased theoretically twice, and practically by 70-90%. Consequently, through a certain grain volume of the grain dryer shafts, it is possible to skip almost twice the drying agent, which leads to an intensification of the drying process, and therefore to an increase in the productivity of the grain dryer.

The processed grain enters from the hopper 1 into the drying and cooling chambers 2, where it is first dried with a hot drying agent (in the upper

25), then (in the lower zone) is blown with atmospheric air, the cooling pans are taken out of the mines by means of exhaust devices (not shown) in the lower part of the mines 2.

30 In the proposed grain dryer, the productivity is increased by 30-50% compared to the known dryers, where the drying: agent leaves the discharge boxes in one

35 side.
