FIELD: elongated material drying processes used for heating drums of smoothing and finishing machines in textile engineering and pulp-and-paper industry, drums in polymeric film production, and also for drying of sewing articles after washing, for example, of passenger's bed cloths in railway transport, as well as in depot.
SUBSTANCE: method involves exposing drum inner surface to infrared radiation with restricted wavelength, said radiation being emitted from three linear emitters arranged in parallel with axis of rotation in spaced relation with respect to rotating cylindrical surface; furnishing linear emitters with reflectors and attaching to immovable pin so that they define apexes of isosceles triangles, which may be rotated relative to pin with following fixing thereof; connecting emitters through voltage regulator to power supply network as parallel electric resistors. Method provides for simultaneous maximal heating of drum cylindrical wall in the region thereof contacting with material to be dried.
EFFECT: simplified adjustment procedure, reduced power consumption and increased efficiency in utilizing of electric energy, and wider operational capabilities.
