FIELD: heating, drying.
SUBSTANCE: invention relates to agriculture and may be used for grain drying, bulk and granulated materials dehydration. The essence of the invention is the design of drain dryer consisting of two drying ducts with boxes, air-distributing system, deflection blades, exhaust unit, heat generator and drying zone. There is a bladed exhaust unit being installed in the first and second zone basis. The unit is provided with movable toothed bars and rotary sections capable of opening at an angle 40°. In addition the opening angle for the central rotary section is 90° due to directional installation of the toothed bars restricting their movement by end contact.
EFFECT: intensification of grain drying process.
