Abstract

894,695. Drying apparatus. LOESCHE, E. G. Oct. 6, 1960 [Oct. 21, 1959], No. 34332/60. Class 34(2) In a granule drying apparatus the granules pass downwardly through the upper part of an upright shaft, then form a free slope on an upwardly tapering cone in the shaft, and pass downwardly into a lower part of the shaft where they are cooled by air which is introduced into the lower part of the shaft, drawn by an exhaustor through a duct placed in the central part of the shaft while hot gas from a burner is passed into the mass of granules through the free slope and then ascends through the upper part of the shaft while drying the granules. The kiln comprises a pre-drying shaft 13 having at its lower end a displaceable telescopic ring 18 which alters the angle of slope of the granulate in the upper part of the annular drying zone 2 to maintain unobstructed outlets 8 in an annular channel 7 through which hot gases from a heating device 6 tangentially enter the drying zone. A cone-shaped part 10 is mounted on an axiallyextending exhaust pipe 9 in the drying zone to upwardly deflect the hot gases from the outlets 8 and to provide a shoot for the downwardly moving granulate, and the pipe 9 has a lower tube section 11 which terminates in a funnel-shaped opening 12 above a cooling air inlet 15 in the base of the kiln to collect the air to cool the material in the lower part of the kiln, the pipe 9, and the part 10 before recirculation to the heating device 6. A discharge device (not shown) beneath the kiln comprises a vibrating screen shoot to grade the granulate, which shoot is cooled and the dust removed by the cooling air before entering the inlet 15.
