(54) DRYER FOR AGRICULTURAL NRODUCT

measures, plan view; on fng. 7 - swivel guides.

Drying chambers 1 with inclined grating bottoms: am 2 for bulk material and with horizontal bottoms-racks 3 for packaged material are located on both sides of the corridor divided by horizontal partitions 4 into compartments 5 and 6. The compartments 5 are connected to gas ducts 7, each of which has own fan 8. Flue ducts are connected by a common collector 9, in which a three-position valve 10 is installed. At nomosh, and this valve the coolant can be directed from each fan 8 to both compartments 5 at once (Fig. 5), as well as from both valves tori - either the lower or upper compartment B 5 (respectively Figure 1 and Figure 4..). In the compartments 5 rotary distributors 11 are installed to evenly distribute the tenon carrier to the chambers 1.

The compartments 5 are communicated with chambers with noraems 12, overlapped with rotary valves 13 with sealing aprons around the perimeter. Each valve 13 has an individual actuator 14, for example, from an actuator (pneumatic, hydraulic, electromechanical). Hatches 15 are installed to exit the spent heat carrier from the dryer. Hatches 16 are installed in bulk for loading chambers 1 and conveyors 17 and 18 are installed, and hatches 19 and conveyors 20 are installed for unloading.

For loading and unloading chambers with packaged material, the dryer has a closure, with openings 21, through which the monorail 22 is used, which is used for mechanization of loading and unloading operations.

Rotary distributors II are two 2.5 mm thick planes of sheet steel, bent along an arc, connected to an angle of 23 by hinges 24. The angle between the planes is manually regulated during the start-up works using left and right thread m and nuts 25. Corner 23 is rigidly fixed to the overlapping compartments. The compartments 6 are connected to the atmosphere by means of valves 26.

In accordance with the position of the shutter 10 shown in FIG. 3, and the position of the valves 13 shown in FIG. 2, the heat source is supplied from both fans 8 through ducts 7 through a collector 9 into the lower compartment 5, from which it is fed through chambers 1 located but one side of the corridor, then through the upper compartment 5 it passes into chambers 1 located on the other side of the corridor, and through the pizhiiy compartment 6 is emitted into the atmosphere. With the position of the valve 10 according to FIG. 4, the material is purged in the chambers in the opposite direction. With the middle position of the valve 10 (Fig. 5), the coolant in parallel and simultaneously enters the chambers 1, located on both sides of the corridor, and the exhaust is emitted immediately from the compartments 6 to the atmosphere.

This dryer allows high-quality drying of various types of agricultural and agricultural products, including

elite seeds of parental forms of hybrid corn.
