Drum dryer for drying the particulate products

For raise effectiveness drying process drum-type installation in which drum the mechanism of creation of various zones providing a necessary temperature and hydrodynamic regime of process of drying in process of product passage on a drum and changes in it of a relationship of various forms of communication of a moisture, and also a process intensification at last stage of drying by creation разряжения in a continuous technological stream of drying is provided is offered. The drum provides formation of a zone of separation of heat-transfer agent by means of the dissector, zones of intensive drying by disposing lobate nozzles in chessboard order with a dividing ring, zones of separation of the completed heat-transfer agent from жома as a result of separator installation in which the elliptic disk having cuts on a straight line from edge to the centre places, with formation of the triangular slot for passage dried pulp and heat-transfer agent, and also zones the final drying by performance of a section of a drum matching to a zone perforated on which length are had spring-loaded lobate nozzles representing the blades connected bow-shaped rod with metal plates, had with outer side of a drum and under the form repeating its contour, thus the bow-shaped rod from the interior of a drum which ends are supplied by springs rest against overhead and bottom persistent screw nuts, and blades and metal plates are installed with possibility of twirl concerning a fastening place on a drum and supplied by reinforcing ribs.
